Introducing the new small business third-party risk management company

12-L: Wireless Controls

This section evaluates how your organization secures wireless networks and devices that connect to your environment.

The questions focus on how wireless access points are configured and managed, what authentication and encryption methods are used, how guest or contractor access is separated from internal networks, and how unauthorized or rogue wireless devices are detected and addressed.

Overall, this section confirms that wireless connectivity does not create unmanaged or insecure entry points into your systems or data.

Explanation: Strong encryption, like WPA2 or WPA3, protects wireless networks by encrypting data in transit, making it unreadable to unauthorized users.

Risks of Incorrect Answer: Use of weak encryption (e.g., WEP) could allow attackers to decrypt sensitive data.

Regulatory non-compliance related to encryption standards could result in penalties.

Applicable Frameworks: ISO 27001 (A.10.1.1): Emphasizes the use of encryption to protect data.

NIST CSF (PR.DS-2): Stresses encryption for data in transit.

PCI DSS (4.1): Requires encryption of sensitive data over wireless networks

Explanation: Quarterly scans for rogue access points help identify unauthorized devices that could be used to bypass network security controls.

Risks of Incorrect Answer: Rogue access points can serve as a backdoor for attackers, compromising sensitive data.

Failure to detect rogue devices may result in data exfiltration or breaches.

Applicable Frameworks: ISO 27001 (A.13.1.3): Mandates monitoring and securing wireless networks.

NIST CSF (DE.CM-3): Recommends detecting unauthorized network components.

PCI DSS (11.1): Requires regular scans for rogue wireless access points
