When technology just works, it’s easy to trust. But too often, we place our trust in technology that doesn’t deserve it. When we do this with technology to provide healthcare, we put the safety of patients and the security and reliability of our global healthcare system at risk.

The institutions that make up our global healthcare system also place their trust in cybersecurity measures and technology to keep their systems running and repelling the unceasing wave of attacks they face. We often hear about the institutions that succumb to cyberattacks, but we don’t read much about the institutions that have been successful at defending their digital perimeter, and ultimately protected their ability to treat and protect patients.

Why were some institutions successful and others not as much? What cybersecurity capabilities made the healthcare institution resilient from these attacks? As we covered in our previous post on how healthcare can strengthen its cybersecurity resilience, establishing visibility and antifragility practices are necessary to repel attackers and build trust in the security and reliability of the technology our global healthcare system relies on.

As we continue our series on healthcare and cybersecurity, we’ll focus next on establishing sustainable visibility mechanisms so cybersecurity teams working in our global healthcare system can secure and preserve patient care and safety.

Visibility is akin to a patient taking 20 different medications but their doctor only knows about 10 of them. That’s the current state of many healthcare organizations’ relationship to the technology used on their networks and systems: They aren’t always aware of what technology is in use, whether it has vulnerabilities, how serious those vulnerabilities are, or how one weakness could lead to another or cascade out of control.

Visibility maps those technology assets (including the software, hardware, configurations, protections, who built it, and where the component parts come from) and help prioritize the importance of those assets in keeping systems and networks secure, no matter how complex the healthcare organization’s use of technology might be.

Building effective visibility

Building visibility into technology assets requires a structured approach. As mentioned in the first blog in this series, using a guide like the NIST Cybersecurity Framework (CSF) provides an important mental model we can use to get a clear picture of the strengths and weaknesses of an organization’s cybersecurity risk profile, and how it applies to the assets the organization seeks to protect.

Cybersecurity author and leader Sounil Yu’s book Cyber Defense Matrix provides an important interpretation of the NIST CSF framework that can help us better understand what visibility we have into technology assets and how they are protected. Visibility is about more than just seeing all assets we have all at once. It’s also about understanding which assets are mission-critical and must be protected at all costs versus which ones are perhaps important but less crucial overall. Without the right balance, we end up trying to protect everything while not protecting what matters enough. This is where structural awareness comes in.

Structural awareness, or the conscious understanding and state of an organization’s assets, is established as one implements controls captured in the NIST CSF functions Identify and Protect. These controls focus on identifying assets, their bill of materials, their creators, their dependencies on other assets, the protections and vulnerabilities they have, and the threats they face. While visibility helps create an accurate map of technology assets, structural awareness builds on that visibility and answers questions such as, “What are the ways the threat actor could compromise that asset? What could be lost? How would it most likely happen? Would I know?”

Yu says that structural awareness is efficiently achieved with the help of automation, and is not as people-intensive as many practitioners, decision-makers, and executives might think. If a cyberattack is like an explosion, cybersecurity teams’ structural awareness helps them understand how the explosion could happen before (or ‘left of’) it goes ‘boom’.

It’s also important to remember that while structural awareness is related to situational awareness in some ways, they are different concepts. Situational awareness refers to mechanisms that are used to detect and respond to an event. Structural awareness mechanisms are ‘left of boom,’ or mechanisms that protect your assets so that events don’t happen. The goal is to stay ‘left of boom’ and avoid being ‘right of boom’. Being proactive in your protections and being ready to respond in either case is really important, nonetheless.

Thinking about assets in terms of users, devices, networks, applications and workloads and data (asset classes), and adopting mechanisms to discover assets of each type through visibility controls suggested by the NIST CSF, will lead to developing structural awareness. Structural awareness can help avoid the boom, but if the boom does happen, it can also help shape the situational awareness needed to react. The Cyber Defense Matrix is an ongoing project, and you can read more about it (and contribute to it) here.

Framing asset discovery for resilience

Cybersecurity teams must map out their organizations’ most critical healthcare services and systems that support them, but that’s easier said than done. Asset discovery can feel overwhelming. Trying to find, count, and audit the hardware, software, users, and data down to the component across even a small part of one’s technology footprint can feel like pushing a dead car up a steep hill. The way to make this easier is to prioritize this effort in the parts of the business where the impact of a quality or safety issue has the potential to create the most harm to the organization and those who depend on it.

A smart place to begin the process to find and evaluate the measurements that an institution uses to monitor those processes.

Healthcare providers: Start with the quality and safety measurements which must be submitted to various regulatory agencies in order to maintain licenses to operate.

• Health insurers: Look at the performance improvement metrics used to ensure subscriber benefits, quality requirements, and legal mandates are being met.
• Health IT services: Use service level agreements for measuring contract compliance with things like uptime, recovery time and point objectives, and response turnarounds.
• Life sciences organizations: Begin with the relevant Good Practice definitions and the metrics used to monitor quality and safety levels of products and services.

When analyzing the types of technology unique to healthcare – like network-connected medical devices such as infusion pumps, implantable pacemakers, ventilators, EKG equipment, and MRI machines – it’s important to ask what are the immediate safety hazards if there was a cyberattack. Not sure how to answer that question? The International Medical Device Regulators Forum produced a risk categorization model that could be helpful in framing that response. Operational technology, like blood bank and sample refrigerators, climate control, air handling, infection control and pneumatic tube systems, may also be used to identify and prioritize inventory efforts.

Once priorities have been set, teams can begin gathering data on critical services, the owners of those services, the systems those owners rely on, and the technology itself.

Inventory tactics on Google Cloud

Building service-technology mapping is not a one-time exercise. Organizations should take the time to automate inventory creation and maintenance, so they can maintain an up-to-date view of all the items in their environment at any given time. This is especially for organizations that have highly dynamic environments.

Google Cloud provides best practices on discovering and cataloging assets in its Cloud Architecture Center. Implement controls found in the Identity and Protect categories using the NIST Framework & Google Cloud technical paper. Automation is your friend when building and maintaining a complete and accurate inventory. Google Cloud Asset Inventory and Security Command Center can be used to inventory a variety of resources running in Google Cloud. Cloud Build, Google Cloud’s CI/CD platform, implements SLSA 1 and provides a trustworthy audit of software artifacts deployed through a managed pipeline. Cloud DLP inventories and labels data stored on Google Cloud Storage and services like BigQuery.

Meanwhile, a number of Google Cloud Marketplace partners have solutions that can help build a comprehensive inventory, and innovation continues to improve our technological options. One emerging field of security technology, called attack surface management, helps discover previously-unknown assets. Finally, our next blog on resilience discusses how to use a software bill of materials (also known by the breezy acronym SBOM) to gain visibility and structural awareness into applications.

It’s important to remember that when starting down this path, the goal is not to gain 100% visibility into every single component on every single device attached to every network supporting every service running. Success or failure is not achieved when the inventory process has reached an arbitrarily-determined ‘percentage complete.’ We want to prioritize expanding visibility and developing structural awareness on assets where safety and quality are at risk, so we can improve their resilience.

And finally, we feel it’s important to emphasize that in the past, healthcare industries have focused mainly on protecting the confidentiality of data. While that’s important, we must evolve security programs beyond protecting confidentiality as its primary (and some cases, only) focus.

To be resilient, we must design and build cybersecurity capabilities that deliver safety, integrity, and availability of the technology that cares for patients directly. As we gain visibility into the technology we depend on to keep us healthy, we improve our understanding about which parts of it we can trust, and which parts we can’t. Improving visibility is an important early step on our path to resilience.

We created Traffic Director to bring to you a fully managed service mesh product that includes load balancing, traffic management and service discovery. And now, we’re happy to announce the availability of a fully-managed zero-trust security solution using Traffic Director with Google Kubernetes Engine (GKE) and Certificate Authority (CA) Service.

When platform administrators and security professionals think about modernizing their applications with a forward-looking security posture, they look for “zero-trust” security. This security posture is based on few fundamental blocks:

1. A means of allocating and asserting service identity (for example, using X.509 certificates)
2. Mutual authentication (mTLS) or server authentication (TLS)
3. Encryption for all traffic flows (TLS encryption)
4. Authorization checks and minimal privileges
5. Infrastructure to make all of the above manageable and reliable

Traffic Director does this by integrating with CA Service, a highly available private CA which issues private certificates expressing service identities, and provides a managed mTLS certificate infrastructure with full certificate lifecycle management. Together, these solve both certificate issuance and CA rotation complexities. 

With Traffic Director managing your service-to-service security, you can now enjoy end-to-end encryption, service-level authentication and granular authorization policies for your service mesh.

With this new capability, you can now:

• Implement mutual TLS (mTLS) and TLS between your services, including certificate lifecycle management. Communications within your mesh are authenticated and encrypted.
• Enable identity-based authorization, as well as authorization based on other parameters (such as the request method). These concepts underpin role-based access controls (RBAC) and enable you to take a “least privileges” stance where only authorized services can communicate with each other based on ALLOW/DENY rules.

mTLS is supported whether you’re using Envoy or proxyless gRPC for your service mesh. Authorization support for proxyless gRPC is coming later this year. Check out our documentation to learn more and get started with Envoy or proxyless gRPC.

Over the past two decades, Google has innovated to build some of the largest and most secure computing systems in the world. This scale requires us to deliver pioneering approaches to cloud security, which we pass on to our Google Cloud customers. We are committed to solving hard security problems like only Google can, as the tip of the spear of innovation and threat intelligence.

Today we’re excited to share the next step in this journey with the completion of our acquisition of Mandiant, a leader in dynamic cyber defense, threat intelligence and incident response services. Mandiant shares our cybersecurity vision and will join Google Cloud to help organizations improve their threat, incident and exposure management.

Combining Google Cloud’s existing security portfolio with Mandiant’s leading cyber threat intelligence will allow us to deliver a security operations suite to help enterprises globally stay protected at every stage of the security lifecycle. With the scale of Google’s data processing, novel analytics approaches with AI and machine learning, and a focus on eliminating entire classes of threats, Google Cloud and Mandiant will help organizations reinvent security to meet the requirements of our rapidly changing world.

We will retain the Mandiant brand and continue Mandiant’s mission to make every organization secure from cyber threats and confident in their readiness.

Context and threat intelligence from the frontlines

Our goal is to democratize security operations with access to the best threat intelligence and built-in threat detections and responses. Ultimately, we hope to shift the industry to a more proactive approach focused on modernizing Security Operations workflows, personnel, and underlying technologies to achieve an autonomic state of existence – where threat management functions can scale as customers’ needs change and as threats evolve.

Today Google Cloud security customers use our cloud infrastructure to ingest, analyze and retain all their security telemetry across multicloud and on-premise environments. By leveraging our sub-second search across petabytes of information combined with security orchestration, automation and response capabilities, our customers can spend more time defending their organizations.

The addition of Mandiant Threat Intelligence—which is compiled by their team of security and intelligence individuals spread across 22 countries, who serve customers located in 80 countries—will give security practitioners greater visibility and expertise from the frontlines. Mandiant’s experience detecting and responding to sophisticated cyber threat actors will offer Google Cloud customers actionable insights into the threats that matter to their businesses right now. We will continue to share groundbreaking Mandiant threat research to help support organizations, even for those who don’t run on Google Cloud.

Advancing shared fate for security operations

Google Cloud operates in a shared fate model, taking an active stake in the security posture of our customers. For security operations that means helping organizations find and validate potential security issues before they become an incident.

Detecting, investigating and responding to threats is only part of better cyber risk management. It’s also crucial to understand what an organization looks like from an attacker’s perspective and if an organization’s cybersecurity controls are as effective as expected.

By adding Mandiant’s attack surface management capabilities to Google Cloud’s portfolio, organizations will be able to continually monitor assets for exposures, enabling intelligence and red teams to move security programs from reactive to proactive to understand what’s vulnerable, misconfigured and exposed.

Once an organization’s attack surface is understood, validating existing security controls is critical. With Mandiant Security Validation, organizations will be able to continuously validate and measure the effectiveness of their cybersecurity controls across cloud and on-premise environments.

Transforming security operations and incident response

Security leaders and their teams often lack the resources and expertise required to keep pace with today’s ever changing threats. Organizations already harness Google’s security tools, expert advice and rich partner ecosystem to evolve their security program. Google’s Autonomic Security Operations also serves as a prescriptive solution to guide our customers through this modernization journey.

With the addition of Mandiant to the Google Cloud family, we can now offer proven global expertise in comprehensive incident response, strategic readiness and technical assurance to help organizations mitigate threats and reduce business risk before, during and after an incident.

In addition, Google Cloud’s security operations suite will continue to provide a central point of intelligence, analysis and operations across on-premise environments, Google Cloud and other cloud providers. Google Cloud is also deeply committed to supporting our technology and solution partners, and this acquisition will enable system integrators, resellers and managed security service providers to offer broader solutions to customers.
