Compression Policy Settings

[Policy] > [Basic Demilitarization Policy] > [Compression] Settings​

The compression tab sets restrictions considering system performance and security when handling compressed files such as ZIP, TAR, and 7Z.
You can limit the number of files and the depth of nesting within a compressed file to prevent system load and block attempts to hide malicious content.

⚠️ The permission to set the basic de-identification policy is granted to [Administrator Type - System Administrator], and
Administrator permission settings can be found under [Administrator Settings] > [Account and Permission Management].

Detailed Description of Settings Items​

Policy NameDescription
Limit on the number of items in a compressed fileLimits the maximum number of files to process within the compressed file.
If there are too many files in the compressed file, the defanging process takes a long time, increasing system load, and other file processing requests will be queued.
---
When set to '0', it operates with no limits and processing time may be longer.
Compression File Subdirectory Depth LimitSpecifies the maximum allowed depth of nested compression.
In general environments, nesting beyond 3 levels is rare, and exceeding this may be considered an attempt to hide malicious content or circumvent policies.
---
When set to '0', it operates with no restrictions, but it is not recommended as it may cause service errors due to abnormal nesting structures.

Input Rules and Precautions​

  • Large compressed files or compressed files containing many files may take a long time to process, so a proper limit on the number is recommended.
  • Abnormal nesting structures can be considered attempts to hide malicious content or attempts to attack the system, so a proper depth limit is recommended.

Reference Notes​

  • After changing the settings, you can check the records and restore them in the [Policy Change History] menu.
