Bridging the Gap Between Vulnerability Scanning and Remediation

In today’s age, computer system security implies identifying potential weaknesses before the cyber criminals identify them. This is what makes vulnerability scanning very necessary. Vulnerability scanning is an automated process that identifies security weaknesses in the network, applications, database, and the cloud. However, this is not the end of the job. While many security software applications excel in highlighting all potential risks, organizations usually find it difficult to fix such issues in good time. The process of fixing identified problems takes so long because of the delay between discovery and resolution. For secure data and effective functioning of the computer systems, companies need to have a strategy from the point of discovery to the point of repair. 

Why the Gap Occurs?

The reason why finding vulnerabilities and fixing them is often so difficult stems from poor workflows, disorganization of data, and cocting priorities of teams involved in the process.

• Too Much Data, Too Little Focus: Vulnerability scanners generate massive amounts of data with literally hundreds or thousands of problems listed. As a result, it is hard to understand where to start for both the security and the IT departments.

• No Prioritization Information: The reports generated by vulnerability scanning tools do not indicate the significance of the systems being scanned. Thus, a simple testing server will be considered equally critical to a live payment system.

• Different Objectives: Security departments are evaluated based on how many vulnerabilities they detect and fix, while IT departments are evaluated based on performance and stability of their systems.

• Manual and Outdated Processes: Storing scan results in spreadsheets or lengthy PDFs hinders the entire process.

Ways to Connect Discovery With Action

Transforming vulnerability scanning from a mere checklist to an actual protection measure demands careful planning, automation, and improved collaboration.

• Focusing on Actual Risk: Integrating severity ratings with data on active threats to determine which vulnerabilities are actively exploited by cybercriminals at the moment is essential. This approach will allow focusing on the most problematic issues.

• Automation of Workflows: Connecting vulnerability scanners with ticketing tools and IT management platforms will allow assigning and tracking of issues automatically.

• Integrating Security into Development Process: Including vulnerability scanning in the development cycle (DevSecOps) is important to identify potential security issues in code even before its deployment to the end-users.

• Providing Fixed Instructions: In addition to a list of vulnerabilities, clear instructions on how to fix each one is vital to help teams address issues without guessing.

• Categorization by Importance: Classifying digital assets according to their importance to the organization will make it easier to understand the actual impact of a detected technical issue on the company.

Building Better Teamwork Between Departments

But this alone is not sufficient to resolve the issue. The success depends not only on technical capabilities but also on teamwork and alignment.

• Align on Common Metrics: Agree on common measurements, such as time needed to resolve high priority risks, so that security and IT teams have aligned objectives.

• Schedule Regular Check-Ins: Rather than reporting, schedule regular meetings where the security team and engineers discuss test results, difficulties, and opportunities for process improvements.

• Make Teams See the Status: Allow individual engineering teams to see the security status of their applications. It will motivate them to solve problems rather than relying on others.

• Make Emergency Plan in Advance: Develop a pre-approved plan of action to be used for addressing critical, newly emerged threats.

Use of Compensating Controls for Vulnerabilities That Cannot Be Patched

In cases when immediate patching of software is not possible due to limitations of legacy software or uptime constraints, certain steps need to be taken to mitigate risks in case of vulnerability scanning.

• Firewall-Based Virtual Patching: Set specific rules on the web application firewall (WAF) or intrusion prevention signature to filter any attacks coming through in order to take advantage of vulnerabilities identified in vulnerability scanning.

• Microsegmentation of Networks: Segregate vulnerable servers from the rest of the company network in order to limit lateral movement in case an attempt to attack the system through unpatched vulnerabilities is made.

• Enhanced Behavioral Monitoring: Intensify monitoring activities and set up alerts to detect and investigate any unusual activity.

• Hardened Access Control: Temporarily restrict administrative access and use multi-factor authentication for any account accessing the vulnerable system.

Conclusion 

Finding a flaw in security is just the first step towards developing a robust and protected digital environment. Although the importance of vulnerability scanning in providing visibility of technical issues lies in the fact that its true potential can be unleashed by combining it with fast and efficient remediation. Through prioritization of the most critical vulnerabilities, automation of the process of their resolution, and fostering collaboration between departments, organizations can transform the output provided by scans into real security measures. The development of the approach that goes beyond mere vulnerability scanning is crucial for the overall security of the organization.
