Deployment of a second virus scanner

Tags:  IBM Domino  Watchdog

If the primary virus scanner malfunctions, for example due to an updating error, a second scanner can be activated and continue to ensure that emails are checked for viruses.

Necessary components
An additionally installed virus scanner

One “iQ-Suite Utilities Virus Scanner“ document for each virus scanner

Two Watchdog Mail jobs

Two Watchdog Mail jobs

A rule that ensures that the second scanner only becomes active if the first one malfunctions.

Step by Step
iQ.Suite Utilities Virus Scanner

1. Configuring the virus scanner with “iQ.Suite Utilities Virus Scanner“ documents

iQ.Suite Utilities Virus Scanner

Use the corresponding document depending on the virus scanner at hand

iQ.Suite - Virus Check all Mails

2. Creation of a Watchdog Job (iQ.Suite - Virus Check all Mails 1) as primary job

View administrator manual for general virus scanner settings.

Important
Important

The job should NOT be classified as critical, since Mailgrabber would no longer process emails in case of malfunction.

Linking the primary virus scanner

3. Linking the primary virus scanner (Virus Scanner 1) to the “ iQ.Suite - Virus Check all Mails 1“ job

Creation of a formula

4. Creation of a formula that examines whether the first virus scanner checked the email.

In words:

@contains($TKFlag50;"IQSUITE - Virus Check all Mails 1");

The formula checks whether the name of the Watchdog job (IQSUITE – Virus Cehck all Mails 1) is entered into the field $TKFlag50 of the primary virus scanner. The entry only exists, if the job was carried out correctly.

iQ.Suite - Virus Check all Mails 2

5. Creation of a second Watchdog job (Backup) - “iQ.Suite - Virus Check all Mails 2“

The job’s priority is lower than that of the primary job. The job runs with same rules as the primary job. In addition, the rule that checks whether virus scanner 1 ran must be active. “Run mode for rules“ must be set to “immediately before the Job“.

Linking the Backup virus scan

6. Linking the Backup virus scan with the job “iQ.Suite - Virus Check all Mails 2“

Usage:

As long as the primary virus scanner runs flawlessly, emails are checked and the second job is not carried out, rendering the second (backup) virus scanner inactive.

As soon as the primary scanner no longer functions correctly, a warning is sent to the administrators.

Primary scanner
The job is deactivated

The job is deactivated and emails are checked by the second scanner.

Note

Licenses are needed for both virus scanners.
