What is Threat and Vulnerability Management?
Threat and vulnerability management is the process of identifying, analysing, prioritizing, and resolving security issues and incidents that could lead to the breach of an organization.
The goal of threat and vulnerability management is to ensure that organizations have complete visibility and control of weaknesses that exist within their security postures, so they can minimize their attack surfaces and successfully reduce organizational risk.
Delivering Threat and Vulnerability Management
The Threat and Vulnerability Management Process
Threat and vulnerability management starts with the discovery of security issues, and concludes with validating whether remediation has been successful, before repeating continuously.
Cyber threat intelligence should be gathered and referenced on an ongoing basis to aid the contextualization and prioritization of issues.
- Discover: Identify threats and vulnerabilities within your organization’s network by carrying out regular penetration tests and vulnerability scans.
- Consolidate: Centralize your threat and vulnerability assessment results in one place. Vulnerability management systems can make this process effortless.
- Assess: Analyse your security issues in line with cyber threat intelligence, such as exploit databases, to establish their severity, the likelihood that they will be exploited, and the impact they could have on your organization.
- Prioritize: Assign severity scores to your assets in line with your analysis, and other factors such as resource availability.
- Remediate: Carry out your threat and vulnerability remediation program to resolve vulnerabilities in line with your organization’s priorities.
- Re-assess: Verify whether your remediation efforts have been successful. Ultimately, your threat and vulnerability management remediation process should reduce business risk.
- Visualize and improve: Continuously improve your threat and vulnerability management processes; resolve any bottlenecks and ensure compliance with your organization’s service level agreements. For example, could you reduce your time-to-remediate (TTR)?
Best Practice Threat and Vulnerability Management
Threat and vulnerability management should be continuous, intelligence-led, and streamlined, to enable IT security teams to analyse, prioritize, and remediate most effectively. Consider these vulnerability management best practices when building a vulnerability management program.
The time between security assessments is the time when your organization could be at risk. Threat and vulnerability management should be an ongoing process to close these gaps.
An intelligence-driven approach to threat and vulnerability management enables IT security teams to gain essential context of their issues, prioritize most effectively, and accurately evaluate risk.
Bottlenecks within threat and vulnerability management processes can lose you precious time. Processes should be streamlined, empowering teams to address issues fast and efficiently.
