Figure 1-1 HP-UX HIDS Components
HP-UX HIDS monitors system activity by analyzing data from the following file sources:
• Kernel audit data
• System log files
HP-UX HIDS analyzes this information against its configured attack scenarios. It then identifies
possible intrusions and misuse immediately following any suspected activity. The suspected
activity simultaneously communicates an alert and detailed information about the potential
attack to the HP-UX HIDS System Manager.
Detection Templates HP-UX HIDS includes a set of preconfigured patterns, known as detection
templates. These templates are the building blocks used to identify the basic types of unauthorized
system activity or security attacks frequently found on enterprise networks. You can customize
the detection templates by changing certain configurable parameters.
Surveillance Groups A surveillance group typically consists of related detection templates; for
example, those related to file system intrusions or web server attacks. Each surveillance group
provides protection against one or more types of intrusion.
Surveillance Schedules A surveillance group is scheduled to run regularly on one or more of
the host systems it is protecting, on one or more days of the week, and at one or more times. This
process of configuring surveillance groups to protect hosts on the basis of a regular weekly
schedule is referred to as creating a surveillance schedule. You can deploy a surveillance schedule
on one or more host systems. You can also create different surveillance schedules for one or more
systems within your network.
Kernel Audit Data Kernel audit logs are generated by a trusted component of the operating
system. The audit logs include information about every system call that is executed on the host.
