Description: An access vector is a data structure that defines the permissions that a subject (such as a user or a process) has to access an object (such as a file, a database, or a system resource) in computer systems. This structure is fundamental in the field of computer security, as it allows for the management and control of who can perform what actions on a system’s resources. Access vectors are essential for implementing security policies, as they help prevent unauthorized access and protect the integrity and confidentiality of information. In design terms, an access vector may include attributes such as the type of access allowed (read, write, execute), the conditions under which access is permitted, and the identification of the subject requesting access. Proper implementation of access vectors is crucial for the security of various systems and networks, as misconfiguration can lead to vulnerabilities that attackers can exploit. In summary, access vectors are a key tool in security management, allowing administrators to effectively define and control access to resources.
