OBSOLETED enable_idds(5)
(Tunable Kernel Parameters)
NAME
enable_idds - enable intrusion detection data source
VALUES
Failsafe
0 (off)
Default
0 (off)
Allowed values
0 (off) or 1 (on)
Recommended values
1 (on) if HP-UX HIDS is installed,
0 (off) otherwise.
DESCRIPTION
Note: From HP-UX 11i Version 3 onwards, the
enable_idds tunable is replaced by the dynamic tun-
able audit_track_paths(5).
If
enable_idds is set to 1, then the HP-UX Host Intrusion Detection System (HP-UX HIDS) can enable
the collection of kernel data for intrusion detection. This also causes additional things to be tracked by
the kernel, resulting in a small degradation in performance (and increase in kernel memory usage), even
if HP-UX HIDS is not in use.
Who Is Expected to Change This Tunable?
Anyone using HP-UX HIDS.
Restrictions on Changing
Changes to this tunable take effect at the next reboot.
When Should the Tunable Be Turned On?
This tunable should be turned on if HP-UX HIDS is installed. The installation will automatically turn on
enable_idds.
What Are the Side Effects of Turning the Tunable On?
The name of the current working directory (and root directory) of every process is tracked, resulting in a
change in memory usage and performance of the system.
When Should the Tunable Be Turned Off?
If HP-UX HIDS is not being used
enable_idds should be turned off.
What Are the Side Effects of Turning the Tunable Off?
When turned off, HP-UX HIDS is unable to use any detection template that uses
idskerndsp. (See the
documentation for HP-UX HIDS for more information on idskerndsp.)
What Other Tunables Should Be Changed at the Same Time?
This tunable is independent of other tunables.
WARNINGS
This tunable has been replaced by
audit_track_paths.
All HP-UX kernel tunable parameters are release-specific. This parameter may be removed or have its
meaning changed in future releases of HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parame-
ter values. After installation, some tunable parameters may no longer be at the default or recommended
values. For information about the effects of installation on tunable values, consult the documentation for
the kernel software being installed. For information about optional kernel software that was factory
installed on your system, see HP-UX Release Notes at
http://www.hp.com/go/hpux-core-docs.
