Which of the following describes egress in the context of attack vectors?

In the context of attack vectors, egress specifically refers to the movement of data out of an organization's network. This often involves unauthorized copying, sending, or transferring of sensitive information outside the perimeter of the network by attackers. Data exfiltration is the act of stealing data, such as confidential information or personally identifiable information (PII), often utilizing backdoors or other methods of evasion to ensure that the data is successfully sent to an external location controlled by the attacker.

Understanding egress is crucial in cybersecurity, as it highlights a key phase in the cyber attack lifecycle where an attacker has successfully infiltrated a system and is attempting to remove data clandestinely. Recognizing this stage is essential for implementing effective data loss prevention strategies that can detect and block suspicious data transfers, thereby protecting sensitive information from being compromised.

The other options provided, such as initial access and system intrusion, pertain to the entry points and methods used by attackers to enter a network, rather than the subsequent extraction of data. Data storage refers to where information is kept but does not directly relate to the concept of data leaving the system.
