Threat Exposure Management

Don’t just see potential attack paths; know what has been exploited and when with VIAVI.

Threat Exposure Management
The VIAVI Threat Exposure Management solution analyzes and visualizes your AWS environment to help you pinpoint which cloud resources are most vulnerable to attack and confirms if and, when exposed assets have been compromised, providing a clear picture of your security posture.

In today's evolving cloud landscape, visibility is paramount for securing your digital assets against cyber threats. VIAVI Threat Exposure Management (TEM) powered by Observer Sentry redefines how you protect your AWS environment, offering a purpose-built solution that empowers you to swiftly identify, prioritize, and address unintended exposures and vulnerabilities. Our innovative approach leverages advanced analytics and visualizations, enabling you to understand your security posture with unprecedented clarity. 

To better understand why VIAVI produced this unique approach to safeguarding your cloud environment, understanding the landscape in which TEM operates is necessary. The cloud offers exceptional flexibility and scalability, but it also presents a unique set of security challenges, leaving organizations vulnerable to a spectrum of cyber threats. Recognizing these common risks businesses face in the cloud is the first step towards implementing a robust and effective security strategy. 

Understanding the Cloud Security Landscape: Common Challenges

TEM addresses many of the common security pain points customers encounter as they strive to keep up with ever-changing cloud environments and service architectures:  

  • Visibility Gaps: Ongoing human, system, and design changes make a passive approach to visibility unsustainable. Locking down systems reactively is not an acceptable approach for managing the interactions and permissive settings that may be creating new attack vectors.  
  • Siloed Views: The elimination of siloed views is one key to optimizing visibility. With customers maintaining multiple AWS accounts and VPCs, each with potentially large numbers of resources, monitoring these assets individually is neither efficient nor adequate.   
  • Automated Changes: Automation and continuous expansion and improvements have heightened the pace of change in the end-to-end AWS environment to one that many teams struggle to keep up with.   

  • Data Volume: Critical insights pointing to compromise can be obscured by the sheer volume of data, potentially leading to extensive delays in detecting and mitigating issues. The rate and complexity of data flows also makes it challenging to understand the impact of a breach without the benefit of intelligent analysis and Continuous Threat Exposure Management (CTEM).   

Attack Path Management

Exposure is inevitable, but it’s not always bad. What may appear to be an undesired exposure may simply be a necessary part of a service architecture and service delivery. Our unique blend of agentless technology, operationalized insights, and advanced automation extends beyond traditional security measures. It transforms your perspective, allowing you to continuously view your environment through the lens of an attacker. This shift from static lists to dynamic visualizations of your AWS ecosystem uncovers hidden interdependencies and vulnerabilities, facilitating a proactive defense strategy that keeps you ahead of potential threats.

Attackers think in graphs, not lists. Think like your adversary. We change how you view your environment, taking it from lists, configuration details, and logs to a visualization of your AWS environment from the attacker’s perspective. VIAVI Observer Sentry identifies paths and interdependencies that linear protection strategies can miss, allowing you to visualize the relationships between assets and prioritize the most critical risks.

Traffic insights bridge the gap between seeing potential exposures and knowing what actually happened, allowing users to answer these critical questions:

  • Did an attacker attempt to connect to an exposed resource?
  • Was the attacker successful? Was it multiple attackers?
  • Is there a breach? Was any sensitive data retrieved?

Continuous Threat Exposure Management (CTEM) 

Continuous Threat Exposure Management (CTEM) takes threat exposure management practices to the next level by continuously monitoring attack surfaces and assessing vulnerabilities. Gartner Research has identified CTEM as an effective, proactive approach to threat mitigation. Continuous threat exposure management practices include:   

  • Scoping the attack surface: This includes both the external attack surface and software as a service (SaaS) applications. 
  • CTEM discovery: Identifying less visible assets, vulnerabilities, and misconfigurations that were not considered during the initial scoping.  
  • Threat prioritization: Establishing a logical ranking system and prioritization algorithms for security risks.  
  • Validating attack pathways: Simulating attacks under real-world conditions to assess how the system reacts.  
  • Mobilization of resources: While automation helps to ensure threats are remediated quickly, resource mobilization considers the responsibilities of key human stakeholders.  

Implementing CTEM processes in an ongoing cycle allows organizations to boost the value of their threat exposure management insights. Interdependencies, vulnerabilities, and exposure pathways are continually changing in the end-to-end AWS environment. This dynamic and flexible approach is necessary to address risks and vulnerabilities in real time.
