Organisations that prioritise security must keep vulnerability management as a top priority to establish a clear approach for identifying issues affecting their systems. Vulnerability scanning is a major component of vulnerability management. It allows you to evaluate your system, infrastructure and software for unpatched loopholes that require remediation.
Let’s have a look at some best practices for vulnerability assessment that can help businesses protect their assets.
How Often Should We Perform Vulnerability Scanning?
This depends upon a number of factors such as compliance standards, organisational changes and your security program objectives. Thus, if your organisation plans to maintain high security level, vulnerability scanning must be a part of your information security program. A vulnerability scan should be carried out after any major organisational, system or infrastructural changes to ensure the prevention of security gaps.
One may also need weekly, monthly, quarterly or annual vulnerability scans to comply with various security standards such as ISO 27001. Generally, it is considered best practice to perform a vulnerability assessment once every quarter. It allows organisations to identify major security vulnerabilities. You can also perform the scans monthly, depending upon your organisational needs. The best way to determine the frequency requirement of your scans is to understand your threats and security structure.
What Compliance Frameworks to Consider?
When complying with security frameworks, you will see that most of them have mandatory requirements of regular vulnerability scans. Some of them require you to conduct vulnerability scanning more frequently than others. Some of these regulatory standards and their requirements are as follows:
ISO 27001: Requires quarterly internal and external vulnerability scanning
Payment Card Industry Data Security Standard (PCI DSS): It requires quarterly scans conducted by an Approved Scanning Vendor (ASV)
Health Insurance Portability and Accountability Act (HIPAA): It requires a detailed risk assessment and vulnerability management, which includes vulnerability scanning.
National Institute of Standards and Technology (NIST): It requires monthly or quarterly vulnerability scanning that depends upon the framework i.e. 800-53, 8001-171, etc.
How to Conduct Vulnerability Scanning?
People often confuse vulnerability scanning is with penetration testing. However, it serves a different purpose. Contrary to penetration testing, a vulnerability scan is an automated process that identifies issues in a system at regular intervals. We can conduct a vulnerability scan with a number of tools.
