Yes, Kali Linux does use sudo as its default privilege escalation mechanism, which allows authorized users to run certain commands with administrative or root-level access. Sudo is built into Kali as part of its security measures, enabling user self-auditing, logging, and control over administrator-level access to system resources. In Kali, it's recommended to only use sudo when necessary and operate as a regular user as much as possible to maximize security and minimize potential damage in case of user error or system breach. Overall, sudo is an essential tool in Kali Linux and is often used for critical systems administration tasks and network penetration testing.
