Cisco Systems has announced a range of new network security products.
The new products form a phase the networking company has dubbed Adaptive Threat Defence (ATD) - security technology that is designed to be flexible and easy to install.
Cisco is also developing technology to cover new security threats such as voice over IP exploits.
Cisco’s new security products cover three main areas: "anti-threat" defences (such as against viruses or spyware), application security, and network control and containment.
For anti-threat defences Cisco has launched the Cisco intrusion prevention system (IPS) version 5.0; the Cisco Anomaly Guard Module and Cisco Traffic Anomaly Detector Module for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers, for spotting suspect data traffic; and the Cisco Security Agent (CSA) Version 4.5 to deal with malware/spyware.
For application security, Secure Sockets Layer (SSL) virtual private network (VPN) services within the Cisco VPN 3000 Concentrator Version 4.7 has been unveiled, together with Cisco PIX Security Appliance Software Version 7.0; and Cisco IPS Version 5.0 and Cisco IOS Software Release 12.3(14)T to tackle voice over IP threats.
For network control and containment side, Cisco has introduced the Cisco Security Monitoring, Analysis and Response System (CS-MARS) and Security Auditor; virtual firewall capabilities in Cisco PIX Software Version 7.0 and Cisco IOS Release 12.3(14)T; and Network Admission Control (NAC) support in Cisco VPN 3000 Concentrator version 4.7.
A number of other companies are working on technologies to help allow networks to defend themselves against increasing attacks, including Cisco rival Juniper.
