What should be considered when implementing strong wireless LAN security measures?

When implementing strong wireless LAN security measures, deploying a wireless Intrusion Detection System (IDS) is critical for enhancing security. A wireless IDS constantly monitors the wireless network for suspicious activities and potential security breaches. By analyzing traffic and detecting unauthorized access points, rogue devices, and unusual patterns, the IDS serves as a proactive defense mechanism, allowing for rapid response to emerging threats.

Utilizing a wireless IDS provides real-time analysis and alerts network administrators to potential vulnerabilities or attacks. This capability is essential for maintaining the integrity and confidentiality of the network, ensuring compliance with security policies, and protecting sensitive data from interception or tampering.

In contrast, the other choices do not contribute to strong security measures. Outdated encryption methods compromise the effectiveness of encryption, leaving data vulnerable to interception. Disabling all firewalls removes a fundamental layer of protection, exposing the network to various threats. Reducing network capacity could potentially limit performance without directly addressing security risks, and it might lead to increased vulnerabilities in the overall design of the network infrastructure.
