About Mac File
The Mac File action can verify the presence of specific files and can verify
one or more file properties in situations where doing so increases confidence in the security of
the client system. If a file with the described properties exists, the access policy passes the
client to the successful branch. If the file does not exist, or a file exists but one or more
properties are not correct, the access policy passes the client to the fallback branch.
The Mac File action provides the following configuration elements and
options:
- Continuously check the result and end the session if it changes
- SpecifiesEnabledorDisabled.WhenEnabled, if the client does not respond for five minutes, the server ends the session.
- FileName
- Specifies the file name for which to check; for example,C:\Windows\Demo\demofile.txt.The file name should include the full path of the file.
- MD5
- Specifies the MD5 checksum. An MD5 checksum provides easily computable verification of the identity of a file using a cryptographic hash algorithm. The MD5 checksum is a 32-digit hexadecimal value. For example, the checksum for a zero-byte file is alwaysd41d8cd98f00b204e9800998ecf8427e.
- Size
- Specifies the size of the file in bytes. The default value is0which is the same as not specifying a size; a size of zero (0) is not verified.A zero-byte file is specified with the MD5 checksum for a zero-byte file in theMD5field.
- Date
- Specifies the file last modified date.The date must be translated first to GMT, and then to a 24-hour clock.
