When it comes to security, access is everything. But many security leaders today don't focus on the importance of privileged access. Here are five ways to ensure you control access to confidential data and why practicing the principles of least privilege is imperative today.

When it comes to security, managing access is a foundational capability—whether you’re talking about a physical space or your cloud infrastructure. If you were securing an office, you wouldn’t give every employee a master key that can open the front door, the mailbox, and the safe. Likewise, when you’re securing your cloud infrastructure, you should limit employees’ access based on their role and what they require to do their job. 

This concept is known as the principle of least privilege, which NIST’s Computer Security Resource Center defines as: “A security principle that restricts the access privileges of authorized personnel… to the minimum necessary to perform their jobs.” In practice, this means assigning credentials and privileges only as needed to both users and services, and removing any permissions that are no longer necessary. 

Keeping the principle of least privilege in mind, here are five practical tips to minimize the surface area of exposed resources on Google Cloud Platform (GCP) and defend against some common attacks. 

Avoid excessive use of broad primitive roles

Primitive roles like Owner and Editor grant wide-ranging access to all project resources. To tighten access security, consider using more specific predefined roles in Cloud Identity and Access Management (IAM), or defining custom roles that are better suited to your organization. For example, if you have a Cloud SQL database, instead of granting the project-wide Editor role to everybody, you could grant the cloudsql.editor role to users who create new databases, cloudsql.client to those who only need to connect to existing databases, and limit cloudsql.admin to database administrators.

Our policy design page has some sample structures and policies for different types of organizations, including startups, large enterprises, and education and training customers.

Assign roles to groups, not individuals

If you assign an IAM role directly to an individual, they retain the rights granted by that role even if they change roles, move around your organization, or no longer require them. A safer and more maintainable option is to place users into logical groups. For example, to manage databases, you could create db-editorsdb-viewers, and db-admins groups, and let users inherit roles from these groups:

Groups can be created within the Admin Console for any G Suite domain, or federated from an external tool like Active Directory. By using groups for ownership, you can also avoid “orphaned” projects and resources—where a project or resource has a single owner who leaves the organization. 

You can assign roles at the organization, folder, project, or resource level. This lets larger organizations easily manage roles for, say, a specific developer team or the entire accounting department. Be aware, however, that a child resource cannot limit roles granted by a parent: a user’s project-level cloudsql.viewer role, for example, will override any resource-level restrictions on any database in the same project.

Reduce the risks of default service account behavior

Service accounts are a special type of account intended for apps that need to access data. If the app’s own private credentials are compromised, however, the attacker then has all the access granted to the app by the service account’s roles.

The Compute Engine default service account, which has the editor role, is enabled for all instances created in a project unless you specify otherwise.

Creating a custom service account to use for creating instances and limiting its roles to the minimum necessary significantly reduces risk. For example, many apps using Cloud SQL only need the cloudsql.client role that lets them connect to an existing database.

An alternative approach is to grant the instance service account minimal privileges and create dedicated service accounts for your apps. This gives you more fine-grained control over each app’s privileges, although you will need to carefully manage the service account credentials.

Reduce risk and control access to your project by using networking features

To enable inter-resource communication, new GCP projects initially have a default network connecting all resources in that project. This is convenient for development, but in this default configuration, if an attacker gains unauthorized access to one resource, they may be able to reach others as well.

To limit this risk, don’t use the default network in production and explicitly specify accepted source IP ranges, ports, and protocols in network firewalls. You should also separate sensitive apps into individual virtual private clouds (VPCs), and if inter-app connectivity is required, use a Shared VPC. In each VPC, use different subnets for public facing services (e.g., web servers and bastion hosts) and private backend services. Allocate public IPs only to instances in the public subnet and add firewall rules with network tags to control which services can communicate with each other. Finally, grant permission to create or modify firewalls and routes only to those directly responsible for the network.

The Secure Instances and Apps with Custom Networks codelab walks you through setting up the public/private subnet configuration above. The Policy design for customers article we mentioned earlier also contains sample network designs for common use cases. For guidance on the tradeoffs of single, multiple, and shared VPCs, see Best practices and reference architectures for VPC design.

Consider using managed platforms and services

If you deploy and manage your own applications, you are responsible for security configuration, including the maintenance of accounts and permissions. You can limit your responsibilities by hosting your apps on managed platforms like Cloud RunApp Engine, or Cloud Functions, or by using fully managed services for databases and processing frameworks like Cloud SQL for MySQL and Postgres, Cloud Dataproc for Hadoop and Spark, and Cloud Memorystore for Redis.

A final note

Security is a priority in all aspects of Google Cloud, but cloud security is a shared responsibility, and ultimately you are responsible for making the right configuration and product choices for your organization to protect your data on GCP. These tips are a great starting point to help reduce your attack surface and help you make more informed risk decisions.

The most insightful time you'll spend today!

The 2022's National Retail Federation (NRF) highlighted emerging themes and technologies dictating the retail industry. The way ahead is in digital along with a mix of physical stores, customer focused web apps, Metaverse and hybrid channels!

For a look ahead at the trends that will animate the retail industry this year, let’s take a look back at the 2022 National Retail Federation (NRF) “Big Show” in NYC.

Attendees at January’s event were treated to tangible examples of how retail challenges are being solved today, including new solutions to help them parse customer expectations and buying patterns, adapt stores into omni-channel experience hubs, and improve data visibility and actionability.

NRF 2022 also took the “omni-channel everything” theme of last year’s show to the logical next level: Enabling the best hybrid experiences. The message came through loud and clear of the importance of integration and interoperability in this new hybrid world – making everything work well together.

The need for modern digital infrastructure to enable this blending of physical and digital retail smoothly is paramount. To that end, technology vendors demonstrated how digital transformation initiatives, such as contactless and real time IoT and mobile applications, need to be built on cloud, edge, and secure connectivity to allow retailers to achieve the modern seamless hybrid retail that today’s consumer wants.

Other prominent themes and technologies highlighted at NRF included: extending engagement in the metaverse, sustainability, physical and digital security, and the agility and adaptability imperative.

The Metaverse and Hybrid (Omni-channel) Experiences


Today, the metaverse is an extension of our lives, enhanced by technology, which exists as a series of virtual worlds. In the future, the metaverse will be an interconnected, endless world where digital and physical lives fully converge. Imagine waiting for an appointment at a real booth on the NRF show floor while your avatar roams a fully fleshed-out digital NRF, meeting other virtual attendees, stopping for coffee at the digital Starbucks, and paying for a coffee that an in-the-flesh Starbucks employee brings to them. Digital and physical selves merge seamlessly in the metaverse, as the worlds draw closer together.

In the metaverse, brands have a digital presence, too. Nike filed seven trademarks late last year, including those for “Nike,” “Just Do It,” and its swoosh logo, and posted openings for virtual designer roles, indicating its intent to make and sell virtual branded sneakers and apparel. It subsequently purchased RTFKT Studios, a company that already makes and sells NFTs and digital sneakers. (In one collaboration with teenage artist FEWOCiOUS, the company sold 600 pair/NFTs of sneakers in just six minutes to the tune of more than $3.1 million.)

The metaverse also opens possibilities for gathering data about consumers and product demand. Imagine a sneaker drop in the virtual world. Certain styles of new kicks sell like gangbusters, giving the brand insight into what might sell IRL, intelligence that leads to trend-right production and less inventory headed for markdown or landfills. The metaverse can be a vehicle for more sustainable operations.

The metaverse further bridges the narrowing gap between digital worlds and physical worlds. Most consumers aren’t outfitting an avatar, but they are moving between online and offline and expect retailers to accommodate those hybrid omni-channel journeys seamlessly. Those demands have accelerated around last-mile delivery and experiences such as buying online and picking up in store (BOPIS) or at curbside, shopping in store and returning merchandise online, adding items to a BOPIS purchase when at the store, or communicating a substitution to the third-party grocery delivery service

Hybrid experiences open opportunities to please the consumer in new ways, but they also add expense and complexity. The need to meet this demand while enabling profitability was a major theme behind many of the technologies discussed at NRF. These included artificial intelligence (AI) for recommending the right product, return logistics software for defining and guiding product-specific reverse logistics workflows, order orchestration and fulfillment applications for omni-channel shopping, and last-mile delivery visibility for optimizing customer experience, to name a few. Also on display were task management applications help to improve and optimize in-store employee engagement, as well as touch-free applications to allow for faster payments and customer self-service checkout. RFID continues to improve inventory accuracy and inventory locating on the shelf, throughout the store, and the supply chain.

Sustainability


NRF 2022 saw a strong focus on sustainability. An NRF/IBV study released at the show highlighted the significant embrace of sustainable shopping by consumers. According to the survey, 62% of shoppers are “willing to change their purchasing habits to reduce environmental impacts.” About half indicated a willingness to pay a premium – on average a 70% premium – for sustainable products and brands.

Retailers are working to improve sustainability and reduce carbon footprint across operations by using sustainable sourcing through the supply chain, the store, and even returns. Tech vendors unveiled a variety of solutions enabled by cloud/edge, AI, computer vision, and IoT/RFID to allow retailers to effectively measure and record their environmental efforts, with the goal of reducing their impact.

Several cloud and digital infrastructure providers showcased sustainability clouds and other technology aimed at asset management with the goal of reducing energy consumption, water usage, waste. Examples included using IoT sensors to reduce water usage, optimizing re-use of store assets, and dashboards that allow retailers to accurately monitor and measure carbon output. However, such sustainability solutions can be most successful when running on the next-generation digital infrastructure that helps retailers better compete and differentiate in today’s omni-channel world.

Physical and Digital Security


According to a 2021 NRF survey, 57% of U.S. retailers reported the pandemic led to an increase in organized retail crime, while 50% reported an increase in shoplifting. When IDC’s Future Enterprise Resiliency & Spending Survey, Wave 10 (November 2021) asked retailers which digital infrastructure investments would provide the greatest strategic advantage in 2022, their #1 response was “cybersecurity and recovery investments.”

A wide range of technology vendors acknowledged retailer concerns with regards to security, fraud, and loss prevention:

  • Networking, connectivity, and edge vendors highlighted multilayer security solutions that promise to protect data from a range of IoT applications that utilize customer and associate data. Many offer security consulting services to address varied threats including ransomware, retail crime, and loss prevention.
  • Security and e-commerce security vendors showcased solutions to prevent fraud and abuse in e-commerce applications as well as omni-channel applications such as BOPIS and curbside pickup, using AI-based analysis for identifying “bad”/risky customers and mitigating risk.
  • Cloud vendors highlighted how retail clouds provide consistent, reliable identity management and data security.
  • POS/payments/store technology vendors emphasized their ability to handle payments securely from any platform with multifactor tokenization, improved identity techniques such as biometrics and voice authentication, as well as AI-enabled and computer vision solutions for loss prevention at checkout and at the door.

The Agility and Adaptability Imperative


On display at the show were multiple flavors of the digital infrastructure technology that retailers need to achieve agile, personalized, data-driven, integrated seamless operations across the many channels of today’s retail landscape. The emphasis was apt. More than half of retailers plan to boost investment in business agility and operational agility over the next 12 months, according to IDC’s Future Enterprise Resiliency & Spending Survey, Wave 10 (November 2021).

Technology vendors highlighted their connectivity investments to enable business and operational agility and their technology investments for better ease of integration, scalability, and the ability to more easily swap out or mix and match applications with integrated platforms, open systems, hybrid cloud, and retail industry clouds.

Vendors also showed off infrastructure to better harness data while enabling its visibility, maximizing its value, and providing the data-driven personalization essential for competitive advantage and differentiation. Highlights included fast, secure connectivity, 5G and Wifi-6, and edge- and cloud-enabled data and AI platforms to generate real-time insights – all designed to enable today’s omni-channel retail.

Advice for the technology buyer


Retailers should consider these key themes from NRF 2022 when making technology investment decisions for 2022 and beyond. To avoid lagging behind those retailers already moving toward thriving into the future, take action to:

  • Enable the seamless, contactless omni-channel approach that today’s consumers want and expect.
  • Replace legacy infrastructure that was not built to handle the modern retail environment that requires the agility and adaptability to seamlessly connect rapidly increasing volumes of data securely and more quickly than ever.

Whether sustainability, adaptability, the metaverse, or security are top concerns, addressing business needs holistically and strategically should be job #1.

The most insightful time you'll spend today!

Transform your security strategy with the {$persona} Survival Guide. Get answers to vital questions and achieve success in today's rapidly changing landscape. Empower your organization with a solid security foundation.

Part of being a security leader whose organization is taking on a digital transformation is preparing for hard questions – and complex answers – on how to implement a transformation strategy.

In our previous CISO Survival Guide blog, we discussed how financial services organizations can more securely move to the cloud. We examined how to organize and think about the digital transformation challenges facing the highly-regulated financial services industry, including the benefits of the Organization, Operation, and Technology (OOT) approach, as well as embracing new processes like continuous delivery and required cultural shifts.

As part of Google Cloud’s commitment to shared fate, today we offer tips on how to ask the right questions that can help create the conversations that lead to better transformation outcomes for your organization. While there often is more than one right answer, a thoughtful, methodical approach to asking targeted questions and maintaining an open mind about the answers you hear back can help achieve your desired result. These questions are designed to help you figure out where to start and where to end your organization’s security transformation. By asking the following questions, CISOs and business leaders can develop a constructive, focused dialogue which can help determine the proper balance between implementing security controls and fine-tuning the risk tolerance set by the executive management and the board of directors.

To start the conversation, begin by asking:

  • What defines our organization’s culture?
  • How can we best integrate the culture with our security goals?

CISOs should ask business leaders:

  • What makes a successful transformation?
  • What are the key goals of the transformation?
  • What data is (most) valuable?
  • What data can be retired, reclassified, or migrated?
  • What losses can we afford to take and still function?
  • What is the real risk that the organization is willing to accept?

Business leaders should ask CISOs and the security team:

  • What are the best practices for protecting our valuable data?
  • What is the business impact of implementing those controls?
  • What are the top threats that we need to address?

CISOs and business leaders should ask:

  • Which threats are no longer as important?
  • Where could we potentially use spending for more cost-effective controls such as firewalls and antivirus software?
  • What benefits do we get from refactoring our applications?
  • Are we really transforming, or lifting and shifting?
  • How should we perform identity and access management to meet our business objectives?
  • What are the core controls needed to ensure enterprise-level performance for the first workloads?

CISOs and risk teams should ask:

  • How can we use the restructuring of an existing body of code to streamline security functions?
  • How should we monitor our security posture to ensure we are aligned with our risk appetite?

Business and technical teams should ask:

  • What’s our backup plan?
  • What do we do if that fails?

Practical advice and the realities of operational transformation

Some organizations have been working in the cloud for more than a decade and have already addressed many operational procedures, sometimes with painful lessons learned along the way. If you’ve been operating in the cloud securely for that long, we recognize that there’s a lot to be gained from understanding your approaches to culture, operational expertise, and technology.

However, there are still many organizations that have not thought through how they will operate in a cloud environment until it’s almost ready – and at that point, it might be too late. If you can’t detail how a cloud environment will operate before its launch, how will you know who should be responsible for maintaining it?

Who are the critical stakeholders, along with those responsible for engineering and maintaining specific systems, who should be identified at the start of the transformation? There are likely several groups of stakeholders, such as those aligned with operations for transformation, and those focused on control design for cloud aligned with operations.

If you don’t have the operators involved in the design phase, you’re destined to create clever security controls with very little practical value because those tasked with day-to-day maintenance most likely won’t have the expertise or training to effectively operate these controls.

This is complicated by the fact that many organizations are struggling to recruit and retain resources with the right skills to operate in the cloud. We believe that training current employees to learn new cloud skills, and giving them the time away from other responsibilities, can help build skilled, diverse cloud security teams.

If your organization continually experiences high turnover in security leadership and skilled staff, it’s up to you to navigate your culture to ensure greater consistency. You can, of course, choose to supplement internal knowledge with trusted partners – however, that’s an expensive strategy for ongoing operational cost.

We met recently with a security organization that turns over skilled staff and leadership every two to three years. This rate of churn results in a continual resetting of security goals. This particular team joked that it’s like “Groundhog Day” as they constantly re-evaluate their best security approaches yet make no meaningful progress. This is not a model to emulate.

Many security controls fail not because they are improperly engineered, but because the people who use them – your security team – are improperly trained and insufficiently motivated. This is especially true for teams with high turnover rates and other organizational misalignments. A security control that blocks 100% of attacks might be engineered correctly, but if you can’t efficiently operate it, the effectiveness of the control will plummet to zero over time. Worse, it then becomes a liability because you incorrectly assume you have a functioning control.

In our next blog, we will highlight several proven approaches that we believe can help guide your security team through your organization’s digital transformation.

The most insightful time you'll spend today!

Cybersecurity is all about speed. It is a critical factor that helps thwart a cyberattack before threat actors inflict damage. Keeping that in mind, we are announcing our new investigative experience in Chronicle Security Operations. Read more!

In cybersecurity, speed matters. Whether a security analyst is trying to understand the details of an alert that was triggered by an indicator of compromise (IoC), or find additional context for a suspicious asset, speed is often the critical factor that will help thwart a cyberattack before threat actors are able to inflict damage.

With speed in mind, we are pleased to announce the general availability of our new investigative experience in Chronicle Security Operations. We are continuing to deliver on our mission to bring the power of Google to security operations and are raising the bar for search and the investigative experience in the SOC.

With this release, SecOps teams will be able to harness Chronicle’s lightning-fast search across any form of structured data. Additionally, the new investigation experience can provide greater flexibility to pivot and drill-down when conducting complex, open-ended threat investigations and surface insights quickly and easily.

Our Unified Data Model (UDM) schema, with its built-in flexibility that can effectively handle a wide variety of security related events, is at the heart of Chronicle’s powerful search. We have scaled this capability by optimizing query responses across structured data. Additionally, analysts can investigate large datasets and build complex queries with a new and intuitive user experience. With user personalization enhancements, analysts can quickly access saved searches and top queries in their environment to improve routine SOC workflows.

With the new investigative experience, security teams can:

  • Drive faster threat understanding with an interactive event results timeline that helps eliminate unnecessary long wait times by streaming results as they are processed to quickly begin threat analysis
  • Use enhanced context and operationalize relevant data for threat analysis with one-click filter-to-query conversion
  • Personalize the analyst experience with saved search and search history functions for quicker analyst knowledge recall
  • Power threat investigation and hunting with a new, improved, highly performant UDM search

Let’s look at an example of how to use the reimagined investigative experience and our new broader, faster search.

In our use-case, a security analyst is investigating a curated detection alert for potentially suspicious behavior on a Windows environment. Additionally, there is a low prevalence domain from host “win-dc-01” with ip “10.166.0.3”. To investigate further, let’s open the UDM Search page and construct a query containing the host and IP information along with destination information of the domain the host was contacting (edge.microsoft.com). Over 70,000 events stream into the investigation interface providing the analyst an immediate picture of data surrounding their alert.

The new interactive events timeline can provide a clear picture of event trends over time with key statistical data which can be easily filtered. Additionally, with the new quick filters, the analyst is able to easily filter out hosts that are known-good to get pertinent information about the domain.

Analyzing value aggregations present in the filter panel, automatically generated by Chronicle, enables analysts to domain values of highest interest, and quickly determine that approximately 800 events were present in the last week that related to edge.microsoft.com URL. Since Microsoft Edge is disallowed in the organization, there should not be any outbound traffic to this type of destination.

As a final step before orchestrating a response in Chronicle SOAR’s case management, the analyst can save their search to quickly recall the steps they took in the future for related investigations.

We have already seen our customers use these new capabilities in preview to build new use cases, accelerate existing threat hunting workflows, and drive faster threat response. We will continue our mission to bring Google speed, scale, and intelligence to the investigative experience, expediting “time to aha” for security analysts, and driving better, faster responses.

The most insightful time you'll spend today!

From cloud security highlights, industry insights on risk governance on digital transformation in the cloud to a lineup of talks and keynotes from Googlers at RSA, there are plenty of thoughts shared with the Cloud CISO perspectives. Learn more.

May is a big month for the security industry. It’s been over a year since we gathered for RSA in San Francisco for one of 2020’s last major in-person events. While we likely won’t be together in person this year, it’s an important time for the security community to come together and reflect on many accomplishments, and to consider the challenges still ahead of us. As the world focuses on security incidents and all the risks that still need resolving, it is important to stand back, on occasion, and also note that immense progress has been made by large numbers of small, medium and large enterprises to protect themselves and their customers against increased threats. What is also amazing is to see organizations do this while accelerating their digital transformations, supporting and protecting customers and managing ongoing remote working challenges. We are privileged to play our part in supporting those great teams. 

It’s also been a busy month for us here at Google Cloud since our inaugural CISO perspectives blog post in April. Today, I’ll recap our cloud security and industry highlights, a sneak peak of what’s ahead from Google at RSA and more. 

Thoughts from around the industry 

  • Risk Governance of Digital Transformation in the Cloud – In our latest Office of the CISO whitepaper, we shared guidance on both the challenges and opportunities of cloud transformation for Chief Risk Officers, Chief Compliance Officers, Heads of Internal Audit and their teams. A misconception we sometimes see among these executives is that moving to the cloud creates more risk to manage. Having held these leadership positions in previous roles, I believe that the cloud is as much a means of managing security, resilience and other risks as it is a risk in its own right. The whitepaper dives deep into considerations for each of these leadership functions as their organization embarks on a digital transformation journey. 
  • The importance of meeting global compliance requirements – Compliance is critical for building trust with customers in regulated industries, especially the public sector. It is worth remembering that in any critical industry, where there can be material impact from incidents, strong industry practices and standards to protect customers are vital (I wrote about this last summer). At Google Cloud, we’re regularly adding new compliance and security certifications to meet our customers’ needs globally. Recently, we expanded our list of FedRAMP High-certified products to include Cloud DNS, and helped our customers in the Asia-Pacific region address various compliance requirements to meet new government regulations for security and data protections. Google Cloud was also the only cloud service provider to complete an annual pooled audit with the Collaborative Cloud Audit Group (CCAG), which is a syndicate of 39 leading European financial institutions and insurance companies who depend on cloud infrastructure and technologies to deliver innovative solutions and experiences for their customers. Having spent most of my career in the financial services industry, I know firsthand the importance of managing risk assessments for outsourced vendors to provide the necessary assurances customers need from their cloud providers. 

RSA 2021 

We have a great lineup of speaking sessions and keynotes from Googlers at RSA this year. Below are the highlights you don’t want to miss: 

  • I’ll be doing a session on May 20 about supply chain resilience, where a panel of experts will dive into how we can adjust risk and security initiatives to handle the next “punch to the supply chain.” Additionally, on May 18 I’ll join many of my esteemed CISO leaders from various industries and governments for a keynote discussion on our top security insights, lessons learned and best practices for how we move forward as an industry to address the next wave of challenges. 
  • Google’s Senior Director of Information Security Heather Adkins will deliver a session on how to build secure and reliable systems at scale, which will cover principles from Google’s Site Reliability Engineering book with the same title (available for free download here). I’m most looking forward to Heather’s advice for how we as an industry can reshape our security thinking, based on modern architectures and technologies that can help organizations design scalable and reliable systems that are fundamentally secure.
  • Nelly Porter, Senior Product Manager at Google Cloud Security, will participate in a panel discussion with security experts on the importance of Confidential Computing technology, how it’s changing the security landscape and where it’s headed. Google Cloud has made great progress in delivering a Confidential Computing portfolio for our customers in regulated industries over the past year, and we’re excited for new milestones in 2021. 

Google cloud security highlights

  • Infrastructure and SRE spotlight – Before I joined Google Cloud, I always admired the infrastructure and benefits this organization delivers that are uniquely Google – from the subsea cable innovations to SRE inventions and principles. Security and resiliency are baked into every layer of our infrastructure. Many of the Googlers who build and support our platform have sat in the same seat as our customers, so they understand those needs intimately. Over the last few months it’s been amazing to watch our technical infrastructure team grow, and the direct reliability, operational resilience and security benefits that team brings to our customers. For example, we’ve opened a new region in Polandannounced the first subsea cable that will directly connect the U.S. to Singapore with fiber pairs over an express route, and released an SRE book focused on how organizations can complete a successful cloud migration.
  • New security foundations blueprint guide – As part of our mission to deliver the industry’s most trusted cloud, we strive to operate in a shared-fate model for risk management in conjunction with our customers. This includes sharing opinionated step-by-step guidance with key decision points and focus areas for how our customers deploy workloads in Google Cloud. This is why we’ve updated our Google Cloud security foundations guide and corresponding Terraform blueprint scripts. These blueprints are tremendously helpful to many stakeholders within an enterprise, like a CISO that needs to understand our key principles for cloud security, or a C-Suite business leader that needs to quickly identify the skills their teams need to meet an organization’s security, risk, and compliance needs on Google Cloud. 

When we think about the types of features to build into products, we have many principles we follow. But the two that I keep coming back to as crucial are:

  1. The need for secure products not just security products. All products should have security built in and while we do build great security products our security and other teams remain focused on constantly enhancing the base levels of security and the security features in all our products. 
  2. Defense in Depth. We don’t just focus on defense in depth from attacks – for ourselves and our customers. We also prioritize defense in depth from configuration errors or other hazards. 

As you see below in some of the highlights of new features and products, these represent our commitment to secure products and all forms of defense in depth. 

  • Workload identity federation – Service account keys are powerful credentials, and can represent a security risk if they are not managed correctly. A safer approach is to use workload identity federation, using IAM to grant external identities IAM roles, including the ability to impersonate service accounts. This lets you access resources directly and eliminates the maintenance and security burden associated with service account keys. We also offered related overall guidance on the best way to use and authenticate service accounts on Google Cloud.
  • VPC-SC Directional Policies – With VPC Service Controls (VPC-SC), admins can define a security perimeter around Google-managed services to control communication to and between those services. Using VPC-SC, you can isolate your production GCP resources from unauthorized VPC networks or the internet. But what if you need to transfer data between isolated environments that you’ve set up? VPC-SC directional policies is a new secure data exchange feature that allows you to configure efficient, private, and secure data exchange between isolated environments. 
  • Anthos service mesh supports VMs as well as clusters – Most enterprise compute resources are still in VMs and many will remain there for a long time to come. In Anthos 1.7,  your VM-based workloads can now take advantage of the same mesh functionality as your container-based workloads.
  • Cloud Spanner CMEK and Access Approvals – Cloud Spanner is Google Cloud’s fully managed relational database that offers unlimited scale, high performance, strong consistency across regions and high availability. Spanner now supports customer-managed encryption keys (CMEK) and Access Approval, Google Cloud’s industry-leading controls to require approval before access to your content by Google support and engineering teams.
  • External Key Manager enhancements – In early 2020 we launched Cloud External Key Manager (Cloud EKM), the industry’s leading Hold-Your-Own-Key (HYOK) product. Using Cloud EKM, the keys used to protect your data stored and processed in Google Cloud are completely hosted and managed outside of Google Cloud infrastructure. Cloud EKM initially launched with support for BigQuery and GCE/PD;  we expanded support for Cloud SQLGKEDataflow Shuffle, and Secret Manager, with CMEK support currently in beta. We also provided in-depth documentation on the functionality, architecture and use cases for Cloud EKM in a new whitepaper.
  • Web App and API Protection solution –  Web applications and public APIs are increasingly important to how organizations interface with their customers and partners, and we’ve seen increased investment in tools to protect these resources from fraud and abuse. Google Cloud’s new Web App and API protection solution is based on the same technology Google uses to protect its public-facing services against web application exploits, DDoS attacks, fraudulent bot activity, and API targeted threats. It provides protection across clouds and on-premises environments.
  • Threat Intel for Chronicle – Most threat intelligence feeds require security teams to do the implementation and legwork. With our new Threat Intel for Chronicle offering, however, our intelligence insights are applied automatically across your security telemetry to present unique observations within your environment. Threat Intel for Chronicle is exclusively curated for enterprise customers by Uppercase, Google Cloud’s intelligence research and applications team to provide our perspective on threats across the internet and surface them as relevant alerts.
