Network Security | Originally designed to protect organisations against network-level attacks, Network Security products evolved when a new generation of malicious code began to target the application layer, and Web 2.0 technologies.
Next Generation Firewalls (NGFW) and Unified Threat Management (UTM) systems are now the de-facto standard for network security. These systems feature traditional network firewall technologies such as Stateful Packet Inspection (SPI) and Denial-of-Service (DoS) protection, as well as advanced security services such as on-box SSL/TLS encrypted traffic inspection, anti-malware, anti-spyware, intrusion prevention system (IPS), URL filtering, and Advanced Threat Protection (ATP). Furthermore, next-generation firewalls inspect every byte of every network packet, and integrate user-identity awareness as well as network application visibility and control capabilities. This allows network administrators to categorise network applications and prioritise business-critical traffic.
