Note: DS-fixed-port and FRS-fixed-port require registry changes on all Global
Catalog, Domain Controller and Member Servers to fix the Directory Services and
File Replication Service ports to single ports vs. the default behavior of fully
dynamic Remote Procedure Call (RPC) that would require TCP/1024-65535 to be
opened.
Permit
Ports to be determined
- Using port maps to map SQL traffic on
whatever implementation-specific ports, for
example TCP/1433 for MS SQL Server or
TCP/3306 for mySQL, to the SQL service so
it will be examined by IPS as SQL traffic. For
example, identifying SQL Injection attempts
within conversations on the ports mapped to
the SQL service.

Determined per

requirements
Note: Although not depicted above, another important use for the port mapping
feature is to map the various TCP ports used for Reverse Telnet sessions via
terminal servers for out-of-band console management of infrastructure devices to
the Telnet service. In other words, Telnet to TCP/2001 is still the Telnet protocol
and should be checked by the IPS for any protocol-specific anomalies and/or
specific signatures.
