IDP
Policies
6.6.2 Packet Content Example
In the following example, the rule is for the
IP
protocol, so the payload search begins at the end of
layer-3. Three strings (S1, S2 and S3) have been defined and have been found after the
Matching
Offset
(10) and within the
Matching Depth
(70). The order in which they are found doesn’t matter.
The same matching offset and depth applies to all strings and string overlaps are allowed.
