Background for this topic.
Bypass is a term that describes the process by which normal security mechanisms and procedures are circumvented. In the context of information security, bypassing can occur at various stages and layers of security within systems, networks, and applications.
This can involve exploiting vulnerabilities, leveraging configuration weaknesses, or using social engineering techniques to gain unauthorized access to resources or data. It may also include methods to evade detection by security software or to override physical security systems. Effective bypass techniques can therefore undermine the integrity of a security system, enabling attackers to carry out malicious activities without being discovered.
