A defense contractor is setting up acceptable programs to run on a new jet. What should they establish?

In the context of setting up acceptable programs to run on a new jet, establishing an allow list is critical for ensuring security and operational integrity. An allow list is a proactive security measure that specifies which applications or software are permitted to run on a system, while all other applications are blocked by default. This approach minimizes the risk of running unauthorized or potentially harmful software, particularly in sensitive environments like that of a defense contractor.

In environments where security is paramount, such as aerospace or military applications, allowing only pre-approved programs reduces the attack surface and helps to prevent malicious software from executing. This method is particularly effective against zero-day vulnerabilities and unknown threats, as it limits the execution of any software that has not been explicitly vetted and approved.

Utilizing an allow list promotes a principle of least privilege, ensuring that only trusted applications can operate within the system. This can improve overall system integrity and security posture, which is vital for the successful operation of critical defense systems.
