Update the Scan engine Manually

Although Trend Micro recommends that you schedule IWSVA to perform automatic updates of the scan engine, you can do it manually, as shown below.
 

  1. Download the latest scan engine from the Trend Micro Web site.

Enter the following search criteria:

  1. Category: Internet Gateway

  2. Product: InterScan Web Security Virtual Appliance

  3. Version: Current product version

  4. Download Types: No selection

  5. Extract the contents of the vsapi-x86-linux-#.###-####.tar.Z file to a temporary directory.
     

  6. Stop the IWSVA HTTP and FTP daemons from the Management Console.
    Go to the Summary page and simply turn off and on the HTTP(S) Traffic and FTP Traffic links.

  7. Back up the following scan engine files:  

    /etc/iscan/lib/libvsapi.so
     

  8. Extract the new scan engine files from their temp directory to the following:

    /usr/iwss/lib/libvsapi.so
     

  9. Ensure the permission is the same as the original engine:

    r    wxr_xr_x iscan iscan libvsapi.so
     

  10. Stop and restart HTTP using the following commands:

    /etc/iscan/S99ISproxy stop
    /etc/iscan/S99ISproxy start
     

  11. Stop and restart FTP using the following commands:

    /etc/iscan/S99ISftp stop
    /etc/iscan/S99ISftp start
