In this article, we will delve into the intricacies of VAPT, highlighting its importance, methodologies, and how it can significantly benefit small and medium-sized companies in Singapore.
What is the Vulnerability Assessment and Penetration Testing (VAPT)?
Vulnerability Assessment (VA)
Vulnerability Assessment is a comprehensive approach to identifying, ranking, and providing solutions for vulnerabilities within a system. It involves a thorough examination of the security posture of an organization’s systems and applications, aiming to uncover any potential weaknesses that could be exploited by attackers. This process is generally automated, utilizing various tools to scan the network and systems for known vulnerabilities.
Penetration Testing (PT)
Penetration Testing, on the other hand, is a more aggressive approach. It simulates cyber-attacks to identify and exploit vulnerabilities in a system. The primary goal is to understand the level of access an attacker could gain and the potential damage they could inflict. This practice helps in validating the effectiveness of the existing security measures and in understanding the real-world implications of a potential breach.
