CCTV CCTV Security Standards and Compliance 3

Question 1

What does 'cybersecurity hardening' of an IP CCTV system typically include?

Accepted Answer

Changing default passwords, disabling unused ports/services, applying firmware updates, and network segmentation

Answer

Cybersecurity hardening involves multiple practices including changing default credentials, disabling unnecessary network services, keeping firmware updated, and isolating cameras on a separate VLAN.

Question 2

What is a 'VLAN' and why is it used in IP CCTV network architecture?

Accepted Answer

A Virtual Local Area Network used to logically isolate camera traffic from other corporate network traffic

Answer

A VLAN segments the camera network from other IT systems, limiting the impact of a compromised camera on corporate systems and reducing attack surface.

Question 3

What is the purpose of 'video integrity verification' or digital watermarking in CCTV systems?

Accepted Answer

To detect or prove whether recorded footage has been altered or tampered with

Answer

Digital watermarking or hash-based integrity verification embeds or generates a unique signature for footage, allowing detection of any post-capture editing or tampering.

Question 4

Which US body publishes cybersecurity guidelines applicable to video surveillance systems in critical infrastructure?

Accepted Answer

National Institute of Standards and Technology (NIST)

Answer

NIST publishes the Cybersecurity Framework and Special Publications (e.g., NIST SP 800-82) that guide cybersecurity practices for industrial and physical security systems including CCTV.

Question 5

What does it mean for a CCTV system to be 'FedRAMP authorized' in a US government context?

Accepted Answer

The system has been independently tested and approved for use in US federal government cloud environments

Answer

FedRAMP (Federal Risk and Authorization Management Program) is a government-wide program providing standardized security assessment and authorization for cloud products used by federal agencies.
