Final answer:
The three cyber security principles critical to the protection of information and information networks are least privilege, defense-in-depth, and situational awareness.
Step-by-step explanation:
The three cyber security principles critical to the protection of information and information networks are:
1. Least Privilege:
This principle states that users and systems should only be given the minimum level of access necessary to perform their tasks. By limiting access rights, the potential for unauthorized access or misuse of information is reduced.
2. Defense-in-Depth:
This principle involves implementing multiple layers of security controls to protect information and information networks. These layers can include firewalls, antivirus software, intrusion detection systems, and encryption.
3. Situational Awareness:
Situational awareness refers to the ability to identify and understand potential threats and vulnerabilities in real time. It involves monitoring and analyzing network traffic, system logs, and other sources of information to detect and respond to security incidents.
