Question 1

What is the purpose of 802.1X authentication in a surveillance network?

Accepted Answer

To control which devices are allowed to connect to the network

Answer

IEEE 802.1X is a port-based network access control standard that authenticates devices before allowing them to connect to a network, preventing unauthorized devices from joining.

Question 2

An attacker floods a surveillance NVR with traffic, making it unable to record video. This is an example of which attack?

Accepted Answer

Denial of Service (DoS) attack

Answer

A Denial of Service attack overwhelms a target system with excessive traffic or requests, rendering it unavailable for legitimate use such as recording video.

Question 3

Which of the following best describes 'two-factor authentication' (2FA) as applied to surveillance system access?

Accepted Answer

Requiring both a password and a second verification factor such as a token or biometric

Answer

Two-factor authentication requires users to present two distinct types of credentials — typically something they know (password) and something they have or are — to verify identity.

Question 4

In digital video surveillance, what is a 'replay attack'?

Accepted Answer

An attacker capturing and retransmitting valid video or authentication data to deceive the system

Answer

In a replay attack, a malicious actor captures legitimate network transmissions and retransmits them to trick systems into accepting them as valid, such as reusing an authentication token.

Question 5

What is the role of a Security Information and Event Management (SIEM) system in a surveillance infrastructure?

Accepted Answer

To collect, correlate, and analyze security event logs from across the network in real time

Answer

A SIEM aggregates log data from multiple systems, correlates events, and generates alerts to help security teams detect and respond to threats across the network.
