In terms of computers, the set of ways in which an adversary can enter a system and can potentially cause damage is called:

Correct option is A

In computer terminology, the Attack Surface refers to the sum of all the points where an unauthorized user (an attacker) can attempt to enter a system and potentially exploit vulnerabilities. This includes software, hardware, and even human interfaces where security can be compromised. Minimizing the attack surface is a key strategy in cybersecurity to reduce risk.

Important Key Points:

1. Attack surface covers all possible entry points for an attack.
2. It can be physical (hardware) or digital (software).
3. Includes weak passwords, outdated software, and unpatched systems.
4. Regular updates and monitoring can help minimize attack surfaces.
5. Smaller attack surfaces are easier to protect.
6. Training employees on cybersecurity reduces the human attack surface.

Knowledge Booster:

• Attack Signature refers to a unique identifier of a specific attack.
• Attack Pattern describes recurring steps or methods used in attacks.
• Attack Path outlines the sequence of actions an attacker takes to breach a system.
• Understanding these concepts aids in developing robust defense mechanisms.
