Skyhigh Security


Information for use by the filtering modules of Secure Web Gateway (also known as filter engines) is updated in regular intervals on an appliance.

For example, updates are performed for DAT files containing virus signatures, for the URL filter database, or for Subscribed Lists, providing filtering information such as IP addresses or URLs.

When an update is performed, relevant data is collected and sent to the Skyhigh Security update servers, which take the role of feedback servers on these occasions.

The data is sent each time Secure Web Gateway contacts an update server to retrieve new updates.

Data collected for updates

The following types of data are collected for updates.

  • Product name, for example, SWG
  • Version number, for example, 7.5.0

  • Operating system, for example, MLOS (McAfee Linux Operating System)
  • Operating system subtype, for example, mlos-1.0-x64
  • ID of the appliance Secure Web Gateway is running on
    This is a uniquely and universally identifying string, known as UUID.

  • System management BIOS (DMI) appliance vendor, for example, Skyhigh Security
  • System management BIOS (DMI) appliance model, for example, Appliance A3

  • For each updatable filter engine:
    • Version number
    • Plugin version number
    • Faulty version number (if a version is faulty)
    • Troubleshooting information, for example, the reason that caused a version to become faulty
