In conjunction with VLAN and custom security zones, security policies can be enforced to prevent unauthorized access to network resources. The ZyWALL USG 100 provides bandwidth management features for traffic prioritization to guarantee or restrict bandwidth usage per interface/protocol. Security staff can allocate bandwidth for a variety of applications or computer hosts on the corporate network, regardless of the direction of the connection. For example, it's possible to assign higher priority and larger bandwidth to time-critical applications such as VoIP and video conferencing for quality transmission services. In addition, ZyWALL USG 100 allows you to keep track of bandwidth usage with comprehensive statistical reports. ZyXEL USG 100 is a VoIP friendly firewall, reducing security risks associated with VoIP. Offering the SIP/H.323 ALG feature it dynamically opens only the required ports during VoIP calls; once a call is closed, the opened ports are also closed to prevent port sniffing. The IDP feature can detect and prevent attacks usually associated with VoIP deployments. Ultimately, by establishing VoIP traffic over VPN's with traffic prioritisation, administrators can minimize security breaches while optimising call quality.
