Vulnerability Detection and Configuration Assessment

A security vulnerability is a weakness in the program code or a configuration error in the system, such as Log4Shell, code injection and so on, that allows an attacker to directly and uninvitedly access a system or network. The Hacker-Powered Security Report from HackerOne in 2022 revealed that over 65,000 vulnerabilities were discovered by ethical hackers in 2022 alone—a 21% increase from 2021. We know that a threat is an adverse or malicious occurrence that exploits a vulnerability. So, why are we so bothered by vulnerabilities? Why can’t we work on threats directly? Why can’t we prevent threats from happening? The simplest answer is we can’t control threats due to their rapidly evolving nature. We can only control and manage vulnerabilities, hence, organizations spend their time and resources on patching security vulnerabilities.
