Vulnerability testing, also known as vulnerability assessment, is a method of detecting security flaws in an IT environment in order to limit the risk of unauthorized access and data breaches. It’s a quick assessment of a company’s cyber-security posture that gives security personnel a list of potential weaknesses and threats.

Penetration testing, which simulates the behaviours of external and internal intruders, is usually performed after vulnerability assessment. Although both processes are part of the Vulnerability Assessment and Penetration Testing (VAPT) system, vulnerability assessment and penetration testing differ in a number of ways.

What are the benefits of vulnerability testing?

Regular vulnerability assessments can provide a number of advantages to a company, including:

Early and consistent detection of security issues in software, networks, servers, and other systems before they are exploited by potential attackers at great financial and reputational harm.

Prompt remedial steps to remove or decrease risks to a level of risk that is manageable.

Compliance with industry cyber-security standards, which helps to avoid costly noncompliance penalties.

Once a procedure has been established, it should be used repeatedly.

Continuous access to up-to-date information on the security posture of the IT infrastructure.

How to perform vulnerability testing?

Planning

You must first establish the process’s goals and scope. This entails assessing the current health of the complete IT infrastructure, determining the testing targets, and selecting the appropriate vulnerability scanner.

Scanning

The targets are scanned with the chosen vulnerability assessment tool in this stage, and a list of the discovered vulnerabilities is prepared.

Analysis

This stage will assist you in comprehending the rationale for the discovered vulnerabilities, their potential impact, and how they can be mitigated. Threats can also be prioritized depending on their severity, urgency, possible damage, danger, and other considerations.

Treating vulnerabilities

After you’ve found and studied the issues, the next stage is to figure out how you’re going to remedy them. There are basically two options: cleanup and mitigation. When a threat can be remedied right away, remediation is employed, whereas mitigation is used to lessen the possibility of a vulnerability if there isn’t a suitable solution or patch available right now.
