Vulnerability Scanning Best Practices

The following are indeed crucial best practices for vulnerability scanning to maintain the security of your systems:

1. Ensure Your Vulnerability Scanner Is Up to Date

Regularly updating your scanning tools is a necessity. It’s crucial to keep them up-to-date with comprehensive coverage of the latest threats and vulnerabilities. Outdated scanners may fail to detect essential problems or could give incorrect results. This emphasis on keeping your tools current is crucial to maintaining adequate security.

2. Schedule Vulnerability Scans Regularly

Schedule vulnerability scans regularly. This way, possible new vulnerabilities are immediately scanned and mitigated before they can be taken advantage of by cybercriminals. The number of scans may vary depending on network size and complexity. However, monthly or quarterly scans constitute the norm.

3. Keep Track of Vulnerability Scan Results

Maintain a complete record of the results of vulnerability scans, including the identified vulnerabilities, their severity levels, and any remediation efforts taken. This documentation is vital to tracking your system security posture over time and proving compliance with regulatory requirements. It also serves as a valuable reference for future scans, allowing you to track the progress of your security efforts and identify any recurring vulnerabilities that need to be addressed.

4. Run Vulnerability Scans on All Assets

Ensure that your organization’s network vulnerability scans encompass all assets within the network, such as servers, workstations, network devices, and cloud infrastructure. Ignoring some assets may create conditions where they can be exploited, adversely affecting the entire network’s security.

5. Verify Vulnerability Scan Results

It is crucial to validate the results manually to eliminate either the false positives or the false negatives. False positives are instances where the scanner incorrectly identifies a vulnerability that doesn’t exist, while false negatives are instances where the scanner fails to detect a real vulnerability. Manual verification involves reviewing the identified vulnerabilities, their severity levels, and their potential impact on the system.

With such practices, organizations will strengthen their cybersecurity position and reduce the possibility of security breaches caused by unresolved weaknesses.
