Diagnosing and treating chronic pain can be complex, difficult, and full of uncertainties for a patient and their treating physician. Depending on the condition of the patient and the knowledge of the physician, making the correct diagnosis takes time, and experimenting with different treatments might be required.

This trial-and-error process can leave the patient in a world of pain and confusion until the best remedies can be prescribed. It’s a situation similar to the daily struggle that many of today’s security operations teams face.

Screaming from the mountain tops “just patch it!” isn’t very helpful when security teams aren’t sure if applying a patch might create even worse issues like crashes, incompatibility, or downtime. Like a patient with chronic pain, they may not know the source of the pain in their system. Determining which vulnerabilities to prioritize patching, and ensuring those fixes actually leave you with a more secure system, is one of the hardest tasks a security team can face. This is where a Vulnerability Exploitability eXchange (VEX) comes in.

The point of VEX

In previous blogs, we’ve discussed how establishing visibility and awareness into patient safety and technology is vital to creating a resilient healthcare system. We’ve also looked at how combining software bills of materials (SBOM) with Google’s Supply chain Levels for Software Artifacts (SLSA) framework can help build more secure technology that enables resilience.

The SBOM provides visibility into the software you’re using and where it comes from, while SLSA provides guidelines that help increase the integrity and security of software you then build. Rapid diagnostic assessments can be added to that equation with VEX, which the National Telecommunications and Information Administration describes as a “companion” document that lives side-by-side with SBOM.

To go back to our medical metaphor, VEX is a mechanism for software providers to tell security teams where to look for the source of the pain. VEX data can help with software audits when inventory and vulnerability data need to be captured at a specific point in time. That data also can be embedded into automated security tools to make it easier to prioritize vulnerability patching.

You can then think of SBOM as the prescription label on a bottle of medication, SLSA as the child-proof lid and tamper-proof seal guaranteeing the safety of the medication, and VEX as the bottle’s safety warnings. As a diagnostic aide, a VEX can help security teams make accurate diagnoses of “what could hurt” and system weaknesses before the bad guys do.

Yet making an accurate assessment of that threat model can be challenging, especially when looking at the software we use to run systems. The ability to quickly and accurately evaluate an organizations’ weaknesses and pain points can be vital to hastening response to a vulnerability and stopping cyberattacks before they become destructive. We believe that VEX is an important part of the equation to help secure the software supply chain.

As an example, look no further than the Apache Log4j vulnerabilities revealed in December 2021. Global industries including healthcare were dealt another blow when Apache’s Log4j 2 logging system was found to be so vulnerable that relatively unsophisticated threat actors could quickly infiltrate and take over systems. Through research conducted by Google and information contributed by CISA, we learned of examples of where vulnerabilities in Log4j 2, a single software component, could potentially impact thousands of companies using software that depend on it because of its near-ubiquitous use.

While a VEX would not capture zero-day vulnerabilities, it would be able to inform security teams of other known vulnerabilities in Log4j 2. Once vulnerabilities have been published, security teams could use SBOM to find them, and use VEX to understand if remediation is a priority or not.

How does VEX contribute to visibility?

A key reason we focus on visibility mechanisms like SBOM and SLSA is because they give us the ability to understand our risks. Without the ability to see into what we must protect, it can be difficult to determine how to quickly reduce risk.

Visibility is a crucial first step to stopping malicious hackers. Yet without context, visibility leaves security teams overwhelmed with data. Why? Well, where would you start when trying to mitigate the 30,000 known vulnerabilities affecting just open source software, according to the Open Source Vulnerabilities database(OSV)? NIST’s National Vulnerability Database (NVD) is tracking close to 181,000 vulnerabilities. We’ll be patching into the next millennium if we adopt a “patch everything” approach.

It’s impossible to address every vulnerability individually. To make progress, security teams need to be able to prioritize findings and go after the ones that will have the greatest impact first. The goal of a VEX artifact is to make prioritization a little easier.

While SBOMs are created or changed when the material included in a build is updated, VEXs are intended to be changed and distributed when a new vulnerability or threat has changed. This means that VEX and SBOM should be maintained separately. Since security researchers and organizations are constantly discovering new cybersecurity vulnerabilities and threats, a more dynamic mechanism like VEX can help ensure builders and operators have the ability to quickly ascertain the risks of the software they are using.

Let’s dig into this VEX example from CycloneDX. You can see the list of vulnerabilities found, third parties who track and report those vulnerabilities, vulnerability ratings per CVSS, and most importantly, a statement from the developer that guides the operator reading the VEX to those vulnerabilities that are exploitable and need to be protected. At the bottom, you’ll see the VEX “affects” an SBOM.

This information allows the user of the VEX document to refer to its companion SBOM. By necessity, the VEX is intentionally decoupled from the SBOM because they need to be updated at different times. A VEX document will need to be updated when new vulnerabilities emerge. An SBOM will need to be updated when changes to the software are made by a manufacturer. Although they can and need to be updated separately, the contents of each document can stay aligned because they are linked.

Increasing resilience powered by visibility—SBOM+VEX+SLSA

VEX could dramatically improve how security vulnerabilities are handled. It’s not uncommon to find operators buried in vulnerabilities, best-guessing the ones that need fixing, and trying to make sense of tens (and sometimes hundreds) of pages of documentation to determine the best, lowest impact fix.

With SBOM+SLSA+VEX, operators are using software-driven mechanisms to conduct analyses and evaluate risk instead of relying on intuition and best guesses. The tripartite SBOM+SLSA+VEX approach provides an up-to-date list of issues and perspective on what needs attention. This is a transformative development in security—enabling teams to get a better handle on doing vulnerability mitigation, starting where it could hurt the most.

Driven by repeated cyberattacks on critical infrastructure such as healthcare, government regulators have taken a more interested stance in software security and supply chains. Strengthening the effectiveness of SBOMs in the United States is a big part of the newly proposed Protecting and Transforming Cyber Health Care (PATCH) Act. The law would require medical device manufacturers adhere to minimum cybersecurity standards in their products, including the creation of SBOMs for their devices, and plans to monitor and patch any cybersecurity vulnerabilities that are discovered during the device’s lifetime.

Meanwhile, new draft medical device cybersecurity guidance from the FDA continues that agency’s involvement in aggressively encouraging medical device manufacturers to improve the cybersecurity resilience of their products. The White House spoke for SBOMs, as well. An Executive Order from May 2021 lays out requirements for secure software development, including the production and distribution of SBOM for software used by the federal government.

Regardless of how these initiatives pan out, Google believes controls like those provided by SBOM+SLSA+VEX are critical to protect software and build a resilient healthcare ecosystem. This approach provides detailed, critical risk exposure data to security teams so they can take necessary steps to reduce immediate and long-term risks.

What do we suggest you do?

At Google, we are working with the Open Source Security Foundation on supporting SBOM development. Our Know, Prevent, Fix report on secure software development creates a broader outline of how Google thinks about securing open source software from preventable vulnerabilities. You can read more about these efforts for securing workloads on Google Cloud from our Cloud Architecture Center. Take a look at Cloud Build, a Google Cloud service that can be used to generate up to SLSA Level 2 build artifacts.

Customers often have difficulty getting full visibility and control over vulnerabilities because of their dependence on open source software (OSS). Assured Open Source Software (Assured OSS) is the Google Cloud service that helps teams both secure the external OSS packages they use and overcome avoidable vulnerabilities by simply eliminating them from the code base. Finally, ask us about Google’s Cybersecurity Action Team, the world’s premier security advisory team and its singular mission supporting the security and digital transformation of governments, critical infrastructure, enterprises, and small businesses.

If you’re a software supplier, please consider our suggestions above. Whether you are or not, you should begin:

• Contractually mandating SBOM+VEX+SLSA (or their equivalent) artifacts to be provided for all new software.
• Train procurement teams to ask for and use SBOM+VEX+SLSA to make purchasing decisions. There should be no reason an organization procures software or hardware with known, preventable issues. Even if they do, the information these mechanisms provide should help security teams decide if they can live with the risks before equipment enters their networks.
• Establishing a governance program that ensures those who control procurement decisions are aware of and owning the risks associated with software they are buying.
• Enabling security teams to build pipelines to ingest SBOM+VEX+SLSA artifacts into their security operations and use it to strategically advise and drive mitigation activities.

At Google, we believe the path to resilience begins with building visibility and structural awareness into the software, hardware, and equipment it rides on as a critical first step. Time will tell if VEX becomes widely adopted, but the point behind it won’t change—we can’t know how we are vulnerable without visibility. VEX is an important concept in this regard.

Next month, we’ll be shifting gears slightly to focus on building resilience by establishing a security culture that obsesses over its patients and products.

Since Aristocrat’s founding in 1953, technology has constantly transformed gaming and the digital demands on our gaming business are a far cry from challenges we faced when we started. As we continue to expand globally, security and compliance are top priorities.

Managing IT security for several gaming subsidiaries and our core business became more complex as we entered into new markets and scaled up our number of users. We needed a centralized platform that could give us full visibility into all of our systems and efficient monitoring capabilities to keep data and applications secure. We also needed the ability to secure our systems without compromising user experiences.

We turned to Google Cloud and Splunk to better manage complexity and support highly efficient, secure, and more dynamic gaming experiences for everyone. We are committed to using today’s modern technologies to give players more optimal experiences.

Bringing our digital footprint into the cloud

When we set out on our digital transformation, we looked to address many business requirements.

These requirements included:

• Regulation: We wanted a platform that could efficiently address our industry’s stringent and global regulatory compliance requirements.
• Player experience: Our IT environment must support smooth gaming experiences to keep users engaged and satisfied.
• Scalability: As we grow and diversify, meeting the changing demands of an increasingly global gaming community, we need an easily scalable platform to align with our current and future needs.

Google Cloud offered us the perfect foundation through solutions such as Compute Engine, Google Kubernetes Engine, BigQuery, and Google Cloud Storage. These acted as the right infrastructure components for us for the following reasons:

• Google Cloud is globally accessible and supports compliance, helping to streamline security and regulatory processes for our team.
• With Google Cloud, we can manage our entire development and delivery processes globally with fast and efficient reconciliation of regional compliance requirements.
• When we need to adjust existing infrastructure or deliver new capabilities, Google Cloud accelerates the process and takes the heavy lifting off of our team.
• Google Cloud allows us to support tens of thousands of players on each of our apps while experiencing minimal downtime and low latency. The importance of this support can’t be underestimated in an industry where players have little to no patience if lags in games occur.

We migrated our back-office IT stack alongside our consumer-facing production applications to Google Cloud given our positive experiences with compliance, security, scalability, and process management. This migration has significantly accelerated our digital transformation while streamlining our infrastructure for faster and more cost-effective performance.

In many ways, Google Cloud has been, with maybe a pun intended, a game-changer for us. For instance, when we suddenly had to support a lot of remote work during the COVID-19 pandemic, native identity and access management tools in Google Cloud allowed us to retire costly VPNs used for backend access and quickly adopt a more easily managed, cost-effective zero-trust security posture.

Accessing vital third-party partners and managed services

Aristocrat has many IT needs best addressed in a multi-cloud environment. Google Cloud is particularly attractive given its strong cloud interoperability, as well as the many products and services available on Google Cloud Marketplace. The marketplace accelerated our deployment of key third-party apps including Splunk and Qualys.

Given the personal information we store and the global regulatory compliance statutes we must oblige, security lies at the heart of our business. Splunk is a critical component of our digital transformation because it offers solutions that provide the enhanced monitoring capabilities and visibility we need. The integration between Splunk and Google Cloud gives us confidence that our data is secure. We know our data can be secure in Google Cloud, while simplified billing through Google Cloud Marketplace makes payments and license tracking easier for our procurement team.

As part of our protected environment, we use the Splunk platform as our security information and event management system, leveraging the InfoSec app for Splunk that provides continuous monitoring and advanced threat detection to significantly improve our security.

We can manipulate and present data in Splunk in a way that provides us with a single pane-of-glass for our hybrid, multi-cloud environment and our third-party apps and systems. Splunk observability tools have likewise helped us to track browser-based applications like our online gaming apps to monitor details related to security and performance.

Splunk and Google Cloud have transformed how we operate. We can now quickly ingest and analyze data at scale within our refined approach to security management by offloading software management to Splunk and Google Cloud. This ability enables us to approach security more strategically, and positions us to integrate more AI/ML capabilities into our products for even greater governance and performance.

This is just the beginning of our journey with Splunk and Google Cloud. We’re excited to see the innovation we can continue bringing to the gaming community worldwide.

Today, we are putting the power of Google’s insights and intelligence in the hands of risk, fraud, and security teams everywhere. We are pleased to announce the general availability of reCAPTCHA Enterprise Fraud Prevention, a new product that uses Google’s own fraud models, machine learning, and intelligence from protecting more than 6 million websites to help stop payment fraud.

reCAPTCHA Enterprise Fraud Prevention can help protect payment transactions by identifying targeted manual attacks and large-scale fraud attempts. It automatically trains fraud models based on behavior and transaction data to identify events that are likely fraudulent and could cause a dispute or chargeback if accepted. 

When threat actors are identified and blocked on any site in the reCAPTCHA network, the intelligence is made available to help protect other organizations from those same attackers. Organizations can then use the scores to send the transaction for manual review or directly block suspicious transactions, drive increased trust in their legitimate transactions, reduce the amount of friction for good users, and reduce erroneous rejection rates.

“Being a safe and trusted place to give and receive help is our top priority. We are constantly innovating, refining and enhancing our fraud defenses and Google’s reCAPTCHA Enterprise Fraud Prevention adds another layer of industry-leading protection for our users. Combining Google’s rich security expertise with GoFundMe’s focus on fraud prevention is already showing promising results as we strive to keep our platform the safest place to give online,” said Matthew Murray, director of risk, GoFundMe.

According to data obtained from our customers using reCAPTCHA Enterprise Fraud Prevention in private Preview, the new solution can help drive comprehensive value for organizations by:

• Reducing fraud losses: Get behavior modeling (not just mouse movements), stop financial damage created by account takeovers (ATOs), and connect fraud and abuse intelligence across your site and application.
• Increasing legitimate sales: Fraud Prevention can help businesses increase their revenue by providing insights to understand who good users are, who may otherwise be caught in an overly aggressive, customer restrictive fraud model.*

These benefits  are enabled for organizations by:

• Preventing advanced attacks: Stopping sophisticated attacks in an environment where attackers use cloud fraud infrastructure, and data leaks, virtual cards and VPN usage are on the rise
• Increasing trust in good transactions: Focus on good approval rates through a unique combination of supervised and unsupervised models
• Improving customer experience: By preventing fraudulent transactions with zero user friction, Fraud Prevention can help businesses protect legitimate users and increase customer retention

Our customers have used these new capabilities in preview in customer experiences that include online checkouts and payment transactions. Fraud Prevention has been used by merchants and payment processors to block millions of dollars in fraudulent transactions in a frictionless way. 

reCAPTCHA Enterprise provides a comprehensive online fraud detection platform that helps prevent fraudulent, spammy, and abusive digital client activity across your web and application footprint. This platform includes Account Defender, which protects users from account takeovers (ATO), frictionless bot management capabilities, and password leak detection to identify compromised accounts. With an additional API call for Fraud Prevention, organizations can leverage a comprehensive solution to secure financial transactions along with core reCAPTCHA Enterprise capabilities. 

To get started, organizations can install a score-based site key on each part of the payment user flow front end and send transaction data when a purchase occurs. This site key helps train site-specific fraud models and start returning fraud scores for each transaction.

Can you keep a secret? Many people struggle to keep secrets. So do organizations. An organization’s digital credentials — its passwords, API keys, tokens, and encryption keys baked into its software code — are its vital secrets, used to authenticate access to protected resources and services.    

The security of these secrets represent one of the biggest risks that enterprises must manage when securing application infrastructure and environments. Fortunately, we have an important tool to help our customers better manage their secrets: Google Cloud Secret Manager. 

Secret Manager is a secure and efficient tool to centrally store, access, manage, and audit your organization’s secrets. As we noted in our April 2023 Threat Horizons Report, insufficient management of credentials and keys is now one of the top security issues facing cloud customers today. In particular, we have observed service account keys being used for everything from insider threats to cross-cloud breaches to intellectual property espionage.

Along with the increasing popularity of DevOps, secrets are used throughout development. In some cases, secrets are coded as plaintext into configuration files or directly into functions, where they can end up exposed in code repositories. If compromised, secrets can be used to gain unauthorized privileged access to enterprise data, infiltrate critical systems, and launch attacks.

Secret Manager can help organizations better manage their secrets even as concerns over potential security breaches grow. Organizations must consider the following four points during their secrets management risk analysis: 

1. Secrets sprawl: As organizations move more workloads to the cloud, the number of secrets they need to manage increases exponentially. This can lead to secrets sprawl, where secrets are stored in a variety of different locations, making it difficult to track and manage them.
2. Human error: Humans are fallible, and this is especially true when it comes to managing secrets. Mistakes, such as accidentally sharing a secret with the wrong person or the misconfiguration of a secret management tool, can have serious consequences.
3. Compliance violations: Organizations that handle sensitive data are subject to a variety of compliance regulations, including PCI-DSS, SOC 2, HIPAA, and GDPR. Without proper management, secrets could lead to potential compliance violations. 
4. Downtime: If secrets are not properly managed or rotated, it could lead to downtime for applications and services that rely on them.

Secret Manager can enable IT teams to keep track of secrets by providing a centralized place to store and manage them. You can access secrets directly from the Secret Manager console, or use the Secret Manager API or SDKs. Secret Manager is also designed to scale with your application. You can store as many secrets as you need without performance issues, and its API-first design lets you extend and integrate into other existing systems. 

Secret Manager integrations in Google Cloud

In many cases, developers save secret configuration details as plaintext in code for ease of use. There are two main risks associated with this approach:

• Anyone with access to secrets can see and copy them. There is no way to enforce any auditing or access controls practices here.
• It becomes difficult to move code between dev, test, and production environments.

Cloud-centered integrations supported by Secret Manager with other Google Cloud services in the software supply chain make it easier and safer to store and access sensitive information. 

The tool is about the secret information being made securely available in build or runtime.

Secret Manager integrations also can play a role in securing sensitive information in the software supply chain:

1. Integration with CI/CD systems used to build and deploy your software

Cloud Code integration can help developers build more secure applications by preventing hard-coding of sensitive configuration data such as passwords, credentials, and tokens in the codebase. It replaces them with secrets which can be programmatically fetched as required. You can create, access, and modify secrets directly from within your favorite IDE without having to navigate away from it. Integration is available for VS Code, IntelliJ, and Cloud Shell Editor.

Cloud Functions integration lets you access and expose secrets as environment variables or as a volume via the filesystem.

Cloud Build: To handle sensitive data in builds, you can store them in Secret Manager and then configure the build steps to access the information directly. In the build steps, you can associate the value of a secret to an environment and you can access this value via an environment variable from scripts or processes. Two common uses for fetching sensitive dependencies during build time are:

• Storing Docker authentication credentials for pull/push of images to Docker hub.
• Creating GitHub pull requests in response to builds.

2. Integration with runtime engines

Cloud Run: Native integration makes it easy to mount secrets in cloud run services. Using this integration, secrets can be made available to containers either as volume mounts or as env variables. Sensitive dependencies can be stored in environment variables, by referencing a secret name stored in Secret Manager instead of storing it as a plain text environment variable. This secret access operation can be done directly from the Cloud Run console without changing a single line of source code. 

If code reads secrets from a file instead of an env variable, the “mounted as volume” option can be used to make secrets look like files to the env vars. During service deployment, the service account used to run the containers are checked to see if they have the required permissions or not, preventing any unwanted access.

Kubernetes and GKE: The CSI driver–provider solution is an open-source work that provides integration with K8s. The driver lets customers centrally store their secrets in Google Secret Manager and consume them in a kubernetes native manner, as files mounted in K8s pods. The solution also comes with additional syncing capabilities. This method of consuming secrets also allows users to take advantage of SM’s capabilities like versioning, managed rotation, default/CMEK encryption and cloud-focused integrations with other Google Cloud services. Work is currently ongoing to provide official support to the driver solution as a GKE component.

Is Secret Manager right for my organization?

Developers carry a big responsibility to protect the sensitive data they are entrusted to work with, and keep secrets out of their code. However, organizations also have a responsibility to provide the tools and solutions needed to help their teams deliver on these expectations. Secret Manager makes it straightforward for developers to store and manage secrets while improving security.
