How to effectively use Vulnerability Management in cyber security

Cyber Security Testing, Industry Trends & Insights, Compliance & Regulation, Cyber Security Technology

With new vulnerabilities being discovered every day the issue of vulnerability management has never been more important. Cyber threats are evolving at a rapid pace, often leaving cyber security researchers struggling to keep up. To avoid the worst case scenarios businesses must understand how to identify, prioritise, and mitigate vulnerabilities before they can be exploited by adversaries. This is where vulnerability management comes in, but how can it be used effectively?

Understanding Vulnerability Management

Vulnerability management is the practice of identifying, classifying, remediating, and mitigating vulnerabilities within digital environments and software. It involves a series of steps that, when executed correctly, help protect systems and data from known and emerging threats.

Identifying Vulnerabilities

The first step in vulnerability management is to identify the weaknesses within your systems. This is typically done through automated scanning tools that crawl through your network, systems, and applications to find known vulnerabilities. It's crucial to conduct these scans regularly, as new vulnerabilities are constantly being discovered. Other services that can assist you with gaining awareness of new threats and vulnerabilities include Managed Digital Risk Protection services. These augment existing cyber security controls by addressing the visibility gap of digital threats outside of the corporate perimeter.

Automated scanning tools and penetration testing

Network Scanners: These tools scan for open ports and misconfigured network services.

Web Application Scanners: They look for security weaknesses in web applications.

Database Scanners: These tools specialise in identifying vulnerabilities within databases.

However, relying solely on automated tools isn’t sufficient. These tools must be supplemented with manual testing, such as penetration testing, to uncover vulnerabilities that automated tools may miss.


Prioritising Vulnerabilities

Once vulnerabilities are identified, they must be prioritised. Not all vulnerabilities pose the same level of risk; some may be theoretical, with no known exploits, while others may be actively exploited in the wild. Prioritisation ensures that the most dangerous vulnerabilities are addressed first.

Factors for Prioritisation:

Severity: How severe would the impact be if the vulnerability were exploited?

Exploitability: How easy is it for an attacker to exploit this vulnerability?

Prevalence: How common is the vulnerability across systems?

Impact: What would be the consequence of an exploit on your operations or data?

Remediation and Mitigation

After prioritising, it's time to remediate the vulnerabilities. Remediation typically involves applying patches, making configuration changes, or updating software. If immediate remediation isn't possible, then mitigation steps should be taken to minimize the risk until a patch can be applied.

Best Practices for Remediation:

Apply Patches Promptly: Software vendors often release patches to address vulnerabilities. Apply these as soon as feasible.

Change Configurations: If a vulnerability is due to a misconfiguration, correct it.

Update Software: Keep all software up to date to ensure vulnerabilities are patched.

Segment Networks: Use network segmentation to limit the potential impact of a breach.

Mitigation could involve adding security controls, changing firewall rules, or isolating the affected system from the network.

Continuous Monitoring: Vulnerability management is not a one-off task—it requires continuous monitoring. Threats evolve, and new vulnerabilities are regularly discovered. Continuous monitoring ensures that you remain aware of new risks and are ready to respond.

Monitoring Tools:

Security Information and Event Management (SIEM): SIEM systems provide real-time analysis of security alerts generated by applications and network hardware.

Endpoint Detection and Response (EDR): EDR tools continuously monitor endpoints for threats and can respond automatically.
