I already have a firewall and a Network Intrusion Detection system (NIDS) at my perimeter. Do I still need Primary Response to protect my server-based applications?
Perimeter defenses, such as firewalls and NIDS, provide an important security measure for computer networks. However, they do not provide a sufficient level of protection for server-based applications. Because many applications communicate with each other and with end users over the Internet, application-level attacks will often penetrate a perimeter via a legitimate access point. Moreover, firewalls and NIDS are unable to inspect encrypted (SSL) traffic, which is not decrypted until it reaches the host. Attacks that successfully navigate the perimeter security layers are often targeting specific application vulnerabilities and are easily detected by Primary Response. According to Gartner Research, 75% of successful attacks exploit application vulnerabilities. Most security experts recommend a layered approach to information security. Primary Response is an application security solution that complements NIDS and other network-layer products, and protects server-based applications more
