About the IPS Signatures Page

To access this page, select SRX > Security Subscriptions > IPS > IPS Signature.

IPS compares traffic against signatures of known threats and blocks traffic when a threat is detected.

Use the IPS Signatures page to monitor and prevent intrusions using the signatures. You can view, create, modify, clone, and delete IPS signatures, IPS signature static groups, and IPS signature dynamic groups. You can delete only the customized IPS signatures, static groups, and dynamic groups that are not used in the IPS or exempt rules.

URL(s)	Displays the URLs that have the details about the signature attack. For example, http://www.faqs.org/rfcs/rfc2865.html.
Category	The category of the attack object. See Table 1.
Recommended	Indicates whether the attack objects are recommended by Juniper Networks (True) or not (False). See Table 1.
Action	The action taken when the monitored traffic matches the attack objects added in the IPS rules. See Table 1.
Keywords	The keywords associated with the IPS signature.
Severity	The severity level of the attack that the signature reports. See Table 1.
BUGS	Displays the list of bugs that are related to the signature attack. See Table 1.
CERT	Displays the computer emergency response team (CERT) advisory number associated with the threat. See Table 1.
CVE	Displays the Common Vulnerabilities and Exposures (CVE) identifier or name associated with the threat. See Table 1.
Signature Details
Binding	The protocol or service that the attack uses to enter your network.
Service	For service binding, displays the service the attack uses to enter your network.
Time Count	The number of times that IPS detects the attack in a specified time scope.
Match Assurance	The positives filter to track attack objects based on the frequency that the attack produces a false positive on your network.
Performance Impact	The performance impact filter used for the IPS signature.
Signature	Displays (in a table) the signature attack objects configured as part of the IPS signature. For each row, the following fields are displayed: No—A unique identifier for the signature attack object. Context—The attack context, which defines the location of the signature where IPS must look for the attack. Direction—The connection direction of the attack. Pattern—The signature pattern (in Juniper Network's proprietary regular expression syntax) of the attack to be detected. Regex—The regular expression to match malicious or unwanted behavior over the network. Negated—Indicates whether the pattern must be excluded from being matched (true) or not (false).
