A VPN is used in surveillance systems primarily to:
Answer: Provide encrypted remote access to the surveillance network
A VPN creates an encrypted tunnel allowing technicians or administrators to securely access the surveillance network remotely.
Which encryption standard is currently recommended for securing Wi-Fi connections used by wireless surveillance cameras in the US?
Answer: WPA2-AES or WPA3
WPA2 with AES or WPA3 provides strong encryption for wireless surveillance cameras, while WEP and original WPA are considered insecure.
What is the purpose of enabling HTTPS instead of HTTP on an IP camera's web interface?
Answer: To encrypt login credentials and configuration data in transit
HTTPS encrypts communication between the browser and the camera's web interface, protecting credentials from being intercepted.
A CST technician discovers that an NVR is running firmware that is 3 years out of date. What is the MOST important reason to update it?
Answer: To patch known security vulnerabilities
Outdated firmware may contain known, publicly disclosed vulnerabilities that attackers can exploit to compromise the device.
What does a firewall rule denying outbound connections from an NVR to unknown external IP addresses help prevent?
Answer: Unauthorized data exfiltration or botnet communication
Restricting outbound traffic from NVRs prevents compromised devices from sending data externally or participating in botnet activity.
Which of the following is an example of a man-in-the-middle (MITM) attack on a surveillance network?
Answer: An attacker intercepting and potentially altering unencrypted video streams
A MITM attack occurs when an attacker intercepts traffic between two devices, which can compromise unencrypted video feeds.
