Take charge of your cybersecurity program foundation with these five steps: discover, assess, prioritize, remediate and measure all assets across your computing environments.
Effective risk-based vulnerability management requires a strong process mapped directly to these five Cyber Exposure phases:
– Discover –
This can be difficult because you likely have diverse asset types such as traditional IT, transitory, mobile, dynamic and operational technology, which often require different discovery technologies. To discover these diverse assets, you may be using disparate technologies from multiple vendors, which increases your acquisition and management costs. Using a variety of disjointed discovery products also results in asset inventory silos, making it difficult—if not impossible—to map diverse assets to your business services.
Understand your complete attack surface
Know which assets support specific business systems
Streamline IT asset management processes
– Assess –
Your asset mix likely includes traditional IT, transitory, mobile, dynamic and operational technology assets. These diverse asset types require different assessment technologies, but they all must be supported in a single vulnerability management platform that delivers a unified view of exposures.
Understand cyber exposures across your attack surface
Audit patching and configuration changes
Inform incident management
– Prioritize –
With a risk-based approach to vulnerability management, your security team can focus on the vulnerabilities and assets that matter most, so you can address your organization’s true business risk instead of wasting valuable time on vulnerabilities attackers may not likely exploit. By understanding the full context of each vulnerability, including the criticality of affected assets and an assessment of current and likely future attacker activity, you can take decisive action to reduce the greatest amount of business risk with the least amount of effort.
Identify vulnerabilities requiring immediate attention
Provide comprehensive vulnerability information to IT Operations for remediation
Inform incident management
– Remediate –
Patching and other remediation activities require a handoff to IT operations staff, along with clear expectations and instructions. There are some instances when patch application isn’t feasible. For example: a patch is not available; applying a patch may do more harm than good; or there are concerns about the system’s sensitivity. In these instances, your security team should consider applying compensating controls as an alternative. By taking a risk-based approach that prioritizes vulnerabilities and assets, you can reduce time and effort needed to secure your attack surface.
Reduced attack surface
Improved operational efficiency
Increased confidence
– Measure –
Track your Cyber Exposure Score (CES), time to assess, and time to remediate and compare those metrics internally and against industry peers. Then communicate those results with your team and key stakeholders to build confidence in your program’s success.
