What are the key principles of information security in the DoD context?

The key principles of information security in the Department of Defense (DoD) context emphasize the protection of sensitive information from unauthorized access, ensuring that access to information is limited and controlled, and implementing layered security measures.

The principle of "need to know" ensures that individuals within the organization can access only the information necessary for their roles, minimizing the risk of exposure to sensitive data. This is critical in a defense environment, where information may be classified and can have serious implications if it falls into the wrong hands.

"Least privilege" complements this by stipulating that users are given the minimum level of access needed to perform their duties. This strategy reduces potential attack vectors within the system and limits the damage caused by compromised accounts. It ensures that individuals cannot access more information than they require, which is crucial for maintaining a secure environment.

"Defense in depth" is a layered security approach that employs multiple defensive measures across various levels of information security. Rather than relying on a single security mechanism, this principle promotes various protections to create a robust defense against potential threats. It includes technical solutions (like firewalls and encryption) as well as operational practices (like regular security training and awareness programs).

Together, these principles create a framework that enhances the security posture of the Do
