Information systems are capable of providing a wide variety of functions (capabilities or processes) and services. Some of these functions and services are installed and enabled by default. The organization must determine which functions and services are required to perform the content filtering and other necessary core functionality for each component of the SRX. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors.

[edit]
show security zones
and, for each interface used, enter:
show security zones
Delete NTP options from zones and interface commands. Re-enter the set security zone command without the "ntp" attribute. The exact command entered depends how the zone is configured with the authorized attributes, services, and options.
Examples:
[edit]
set security zones security-zone
