Part IV, "Security Monitoring": To ensure that a network remains secure, it's important to regularly test and
monitor the state of security preparation. Network vulnerability scanners can proactively identify areas of
weakness, and intrusion detection systems can monitor and respond to security events as they occur. Using
security monitoring solutions, organizations can obtain unprecedented visibility into both the network data
stream and the security posture of the network. Part IV includes the following chapters:
Chapter 20, "Network Intrusion Prevention," covers network security monitoring using the network-based
appliance sensor technology, Intrusion Prevention System (IPS). The chapter provides a comprehensive
coverage of the sensor operating system (OS) software functions and features.
Chapter 21, "Host Intrusion Prevention," covers network security monitoring using the host-based
technology, Host Intrusion Prevention System (HIPS). The chapter provides comprehensive details of
Cisco Security Agent (CSA) technology providing solution architecture, components, and CSA deployment
using CSA MC.
