the latest updates on the Support site.
WARNING!
Make sure you upload updates directly from the Support site or by
clicking Update. Do not transfer them by email, as they may become corrupted
during transmission.
2.
Under Updates, select the update that you want to apply and click Install. If
you are installing an update that requires a system reboot, you must confirm
that you want to restart the system.
The update is installed and you can click Continue to continue with

Importing SEUs and rule files
If you licensed the IPS component, you can import the latest version of the
Security Enhancement Update (SEU). SEUs contain new and updated standard
text rules and shared object rules that you can use to detect potential attacks
against your network and its assets. In addition, an SEU can also provide IPS with
an updated version of Snort, as well as features such as new preprocessors and
decoders.
IMPORTANT!
SEUs can contain new binaries. Make sure your process for
uploading and installing SEUs complies with your security policies.
TIP!
If no SEU update is available, click Continue and continue with
“Configuring a system policy” on page 32
