iSACA Cybersecurity Fundamentals Certification Practice Exam

Which of the following describes egress in the context of cybersecurity?

1. Intrusion attempts

2. Data removal from a system

3. Vulnerability exploitation

4. Attacking a target

The correct answer is: Data removal from a system

In the context of cybersecurity, egress specifically refers to the movement of data out of a network or system. This concept is critical for understanding how information flows and how it can be managed or secured. When considering the operational definitions, egress signifies any action where data is being transferred from a source to an external destination. This could involve sending data to a connected device, transferring files out of a secured environment, or even data leaks. By establishing robust egress controls, organizations can monitor and restrict this flow to prevent unauthorized data exfiltration, thereby mitigating risks associated with data breaches. Other options like intrusion attempts, vulnerability exploitation, and attacking a target mainly deal with various forms of attacking or compromising a system, rather than the specific aspect of data leaving that system. Egress focuses on the movement of data itself, which is a fundamental aspect of cybersecurity strategy for protecting sensitive information.
