Custom Remediation Module
A remediation module is a program or script, packaged with associated files, that is
written to perform specific actions or responses to conditions on your network that
violate correlation policies.
Custom remediation scripts can be written in either of the following languages:
• bash
• tcsh
• Perl
• C - If you write your remediation module program in C, it must be pre-compiled and statically
linked, with the exception of links to routines in glibc.
Additionally, you must create an XML document called module.template to define the
information your module requires from the Remediation subsystem.

Enhanced High-Availability
• Synchronizing critical “state” information between individual devices in a
high-availability cluster.
• TCP Strict State Enforcement – allows TCP sessions to continue without having to reestablish the connection.
• Unidirectional Rules – enables a flow allowed by a unidirectional rule to continue even
if failover occurs midstream.
• Blocking Persistence – flow state including verdict (blocked or allowed) is shared to
ensure verdict is persistent after failover
• Dynamic Network Address Translation (NAT) – dynamic mapping of IP and ports
remains persistent after failover
• Supports clustered appliance stacks (8250, 8260, 8270 and 8290
65
Enhanced High-Availability
Devices directly connected via the HA Link external interfaces
Clustered devices must be the same model with identical NetMods
HA Link interface depends upon the potential
throughput of each cluster member
66
IPv6 Awareness & Support
• IPv6 support is fully integrated
• From policies to event viewers to table views.
• Network discovery of IPv6 hosts
• User Agent, Impact Flag and rule
recommendations all work with IPv6
• Nmap can scan over IPv6
• IPv6 discovery events can stream via eStreamer
