What are the two modes of attack based on line of attack?

• A. Physical Attacks and Social Attacks
• B. Insider Attacks and External Attacks
• C. Remote Attacks and Local Attacks
• D. Natural Disaster Attacks

Answer: (B)

Attackers can be classified by where they originate: inside the organization or from outside. An insider already has some level of access—employees, contractors, or partners—so they can abuse privileges, bypass controls, or exfiltrate data from within the trusted environment. External attackers start outside and attempt to breach the perimeter, gain a foothold, and then move laterally to reach sensitive assets. This distinction guides defenses: for insider threats, enforce least privilege, strict access controls, ongoing monitoring, and an insider threat program; for external threats, focus on strong authentication, network segmentation, perimeter defenses, and robust incident response. Other options mix unrelated ideas like physical or natural events, which don’t align with the main distinction of attack origin.
