Contexts

Use this page to configure the settings Vulnerability ProtectionDeep Security will use to determine whether a protected computer has Internet connectivity or not. Some Vulnerability ProtectionDeep Security Rules can be applied conditionally depending on the computer's network connectivity conditions. This is known as "Location Awareness". The Internet connectivity condition options for a particular rule can be configured on the Options tab of the rule's Properties window. The Internet Connectivity Test can also be used when implementing Interface Isolation. (See Interface Isolation and Interfaces/Interface Types.)

Internet Connectivity Test

• URL for testing Internet Connectivity Status: The URL to which an HTTP request will be sent to test Internet Connectivity. (You must include "http://".)
• Regular Expression for returned content used to confirm Internet Connectivity Status: A regular expression which will be applied to the returned content to confirm that HTTP communication was successful. (If you are certain of the returned content you can use a simple string of characters.)
  Vulnerability ProtectionDeep Security uses POSIX basic regular expressions to match interface names. For information on basic POSIX regular expressions, see http://pubs.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html#tag_09_03
• Test Interval: The time interval between connectivity tests.

Example

For example, to test Internet connectivity, you could use the URL "http://www.example.com", and the string "This domain is established to be used for illustrative examples in documents" which is returned by the server at that URL.
