Updating malware signatures

Updating malware signatures enables the BIG-IP system to discover new types of generic malware.
  1. On the Main tab, click
    Security
    Security Updates
    Fraud Protection Service
    Signatures Update
    .
    The Signatures Update screen appears.
  2. If you want the BIG-IP system to automatically update signatures if it determines that an update is available during the daily check, select the
    Enabled
    check box for the
    Update Automatically
    setting.
    1. If you want to retain the current update setting, click the
      Save Settings
      button.
    • If you set
      Update Automatically
      to
      Enabled
      , you are finished configuring signature updates and do not need to perform any of the following steps.
    • If you set
      Update Automatically
      to
      Enabled
      , the Delivery Mode setting is irrelevant and is not displayed.
  3. If you did not set the
    Update Automatically
    setting to
    Enabled
    , choose one of the following delivery modes:
    • Select
      Automatic
      if you want to download and install a signatures update file from the Update server if it is available.
    • Select
      Manual
      if you want to update signatures by uploading a signatures update file received from F5 support (not from the Update server).
    The default setting for Delivery Mode is
    Automatic
    . Setting Delivery Mode to
    Manual
    is a temporary setting and only valid as long as you are in the update screen. When you leave the update screen, Delivery Mode reverts back to
    Automatic
    .
    1. If you set Delivery Mode to
      Manual
      , in the
      Upload File
      field upload the image file received from F5 support by clicking on the browse button and selecting the file. This option appears only if Delivery Mode is set to
      Manual
      .
  4. If you received a notification that updates are available or have uploaded a signatures update file that you received from F5, click the
    Install Updates
    button to install the update.
    After a signatures update has been installed, it takes a few minutes for the update to be applied.
  5. In addition to the notice that you will receive if the daily update check determines that an update is available, you can also check for available updates by clicking the
    Check for Signature Updates
    button.
    This button is useful in the case where a new update has become available after the daily check was performed. If you click this button and an update is available, you will receive a notification.
