IDS/IPS

摘要

I think I installed my first IDS back in 2000 and my first IPS in 2002. Back then, we had software- or appliance-based offerings, and we chose to install them either in front or just behind our firewalls for an added level of security. The technologies back then were a bit challenging to deploy and did not offer a wide array of configuration or management options. As these technologies morphed into stateful firewalls and, eventually, unified threat management (UTM)-style products, the traditional intrusion detection/intrusion prevention systems have continued to provide a valuable service in our layered defense/security architectures.
