What is Network Security Stack?
The term ‘Security Stack’ is used to help visualize the many different cyber security tools (many times depicted in layers) that an organization uses to protect themselves from cyber threats. More specifically the ‘Network Security Stack’ are those cyber security tools which are network attached and conducting some sort of network traffic/packet analysis to detect and block threats. These could include a wide range of tools including firewalls (FW/NGFW), network intrusion prevention/detection systems (NIPS/NIDS), security information and event management systems (SIEM), secure web gateways (SWG), threat intelligence feeds/platforms, security analytics solutions and advanced malware analysis platforms. Examples in the market today of companies who provide technologies for this layer are Palo Alto Networks, FireEye, Cisco, among others.
