Securing the WLAN

WLANs Are Inherently Vulnerable to Attack

Because WLANs use radio transmissions, they are inherently more difficult to secure than wired LANs. Simple encryption and authentication techniques such as WEP prevent outsiders from casually or inadvertently browsing your WLAN traffic, but they cannot stop a deliberate attack. WPA, and particularly WPA2 is quite secure today, and meets the need of the most demanding security officer. Even the best passive defenses, however, must be paired with an active defense in order to really work.

  1. Attempted breaches must be identified and stopped.
  2. Networks must be monitored to ensure that security policies are followed.

Monitor Compliance to Security Policies

OmniPeek can be used to monitor compliance with security policies, and to identify, intercept, log, and analyze unauthorized attempts to access the network. It can automatically respond to security threats in a variety of ways, making it ideal both for monitoring and for more focused analysis.

Real-time Expert Alerts

  • Denial of Service (DoS) attacks
  • Man-in-the-Middle attacks
  • Lapses in security policy (such as wrong or default configurations)
  • Intrusion detection
  • Rogue access point and unknown client detection
  • Adherence with common wireless network policies
OmniPeek alerts you to network policy violations, like connections to unauthorized networks

Monitor Compliance to Security Policies

With OmniPeek, you can assign levels of trust to any node, making it easy to tell at a glance who is who. Keeping a current list of your own network’s members is easy, and allows you to automatically identify and easily locate rogue APs. Assign a value of Trusted to the devices that belong to your own network. The intermediate value of Known lets you segregate sources that are familiar, but beyond your own control, such as an AP in a neighboring office. Nodes classified as Unknown (the default) can be quickly identified.

Monitor Compliance to Security Policies

Security Policies Monitored in Real Time

Security issues are not always malicious. Even with well-established security policies in place, well-intentioned users can be inadvertently violating these policies due to misconfigured security settings or simply an overall lack of knowledge of wireless security. With OmniPeek, security policies established around common operating procedures can be monitored in real time, providing instantaneous alerts when a single client is in violation of the policy.
