<div><p>This sample traffic regulation policy traces suspicious traffic
|
||
|
|
across the network, such as an unusually high rate of TCP connections.</p>
|
||
|
|
<div class="section"><p>Traffic regulation events correlate to completed
|
||
|
|
handshakes for connections. The intrusion detection system generates statistics
|
||
|
|
and when user-specified thresholds are met, the system generates an audit
|
||
|
|
record. Use the ibm-idsMaxEventMessage parameter in the IDS policy file to
|
||
|
|
limit the number of records written to the audit journal.</p>
|
||
|
|
<p>This policy
|
||
|
|
points to a single IDS traffic regulation (TR) condition and a single IDS
|
||
|
|
action. The IDS condition selects the TCP protocol, local port 8000, and a
|
||
|
|
local host IP address.</p>
|
||
|
|
<p>The IDS action specifies a TCP
|
||
|
|
connection limit of 1000 for the listening server, a statistics interval of
|
||
|
|
10 minutes, and 10 percent of the TR connections. This example shows the local
|
||
|
|
host IP addresses as a range of addresses from 9.10.11.000 through 9.10.11.255.</p>
