Application or Service Objects
Service objects represent network services that use Transport
Layer protocols such as TCP, UDP, RPC, and ICMP. You use service objects
in rules to specify the service an attack uses to access your network.
Juniper Networks provides predefined service objects, a database of
service objects that are based on industry-standard services. If you
need to add service objects that are not included in the predefined
service objects, you can create custom service objects. IDP supports
the following types of service objects:
-
Any—Allows IDP to match all Transport Layer
protocols.
-
TCP—Specifies a TCP port or a port range
to match network services for specified TCP ports. You can specify junos-tcp-any to match services for all TCP ports.
-
UDP—Specifies a UDP port or a port range
to match network services for specified UDP ports. You can specify junos-udp-any to match services for all UDP ports.
-
RPC—Specifies a remote procedure call (RPC
from Sun Microsystems) program number or a program number range. IDP
uses this information to identify RPC sessions.
-
ICMP—Specifies a type and code that is
a part of an ICMP packet. You can specify junos-icmp-all to
match all ICMP services.
