Level of Access Needed for Successful Attacks

A.

The metric that is used to capture the level of access needed to launch a successful attack is "privileges required."

Privileges refer to the level of permission or authorization that a user has to access a system or network. The higher the level of privilege required to launch an attack, the more difficult it is for an attacker to successfully execute the attack.

For example, if an attacker needs administrative privileges to install malware or gain access to sensitive data, it will be more challenging for them to achieve their goal compared to if they only need basic user-level privileges.

Therefore, the privileges required metric is an important indicator of the overall risk associated with a particular attack. It helps security analysts and incident responders to assess the severity of a threat and prioritize their response accordingly.

In contrast, user interaction, attack complexity, and attack vector are other metrics that are used to measure different aspects of a cyber attack. User interaction, for instance, refers to the degree of involvement required from the user to execute the attack, while attack complexity measures the technical sophistication of the attack. Attack vector, on the other hand, refers to the method or pathway that an attacker uses to gain unauthorized access to a system or network.
