IPS Software Versioning
Service packs are cumulative following a base version release (minor or major). Service packs are used
for the release of defect fixes with no new enhancements. Service packs contain all service pack fixes
since the last base version (minor or major) and the new defect fixes being released. Service packs
require the minor version.
Signature updates are cumulative and increment by one with each new release (for example, S145, S146,
S147). Signature updates include every signature since the initial signature release (S1) in addition to
the new signatures being released. Signature updates require the minimum version listed in the filename.
To install the most recent signature update, you must have the most recent minor version. Service packs
are dependent on the most recent minor version, which is dependent on the most recent major version.

System image files (IDS-4215, IPS-4240, IPS-4255 NM-CIDS, IDSM-2, AIP-SSM-10, and
AIP-SSM-20)—Full IPS application and recovery image used for reimaging an entire sensor.
Recovery partition image file—A recovery partition image file is a partition on the sensor that
contains a full IPS application image to be used for recovery.
Maintenance partition image file (IDSM-2 only)—A maintenance partition image file is used to
reimage the maintenance partition of IDSM-2. Maintenance partition files are released when new
major or minor versions of the maintenance partition are released. Maintenance partition image files
are not released for service packs to the maintenance partition. A service pack may be released to
address defects identified in existing maintenance partition images, but new maintenance partition
images are not produced for subsequently released service packs.

The maintenance partition image file does not contain a signature designator.
