The following events trigger decompression rules:
|
A compressed file to be transmitted matches a policy and the action on the compressed file is Pass (transmit the file). |
For example, to monitor .ZIP files that users are transmitting, you defined a file attribute (.ZIP), added it to a template, used the template in a policy, and then set the action to Pass. Note:
If the action is Block, the entire compressed file is not transmitted and therefore, there is no need to scan the files it contains. |
|
A compressed file to be transmitted does not match a policy. |
In this case, Apex One will still subject the compressed file to the decompression rules to determine which of the files it contains should be scanned for digital assets and whether to transmit the entire compressed file. |
Both events have the same result. When Apex One encounters a compressed file:
-
If Rule 1 is not satisfied, Apex One allows the transmission of the entire compressed file.
-
If Rule 1 is satisfied, the other two rules are checked. Apex One allows the transmission of the entire compressed file if:
-
All scanned files do not match a policy.
-
All scanned files match a policy and the action is Pass.
The transmission of the entire compressed file is blocked if at least one scanned file matches a policy and the action is Block.
