Outbreaks
happen when viruses/malware, Trojans, worms, or other spyware/grayware
suddenly attack many Exchange servers or personal computers on your
network. There are many reasons why an attack might occur such as
out-of-date components, poor configuration of anti-virus software,
or a new malware arising for which there is not yet a pattern file.
Outbreaks are a critical time when administrators must endure a
chaotic, time-consuming process of communication, often to global
and decentralized groups within their organizations.
The actions that administrators take when outbreaks happen can
be broken down into four general stages:
-
Confirming that the security incident is a legitimate
problem and not a false alarm
-
Responding to the security incident
-
Analyzing the security incident
-
Recovering the Exchange servers and mailboxes
ScanMail has some
very useful features that can assist administrators in every stage
of an outbreak. Consider the following features when an outbreak threatens:
-
To confirm that the security incident is
truly a malware outbreak:
-
Check the Trend Micro
website for virus/malware alerts and the latest security advisory
information.
-
Check ScanMail
notifications. ScanMail can be configured to automatically send
alerts when outbreak conditions exist. In addition, ScanMail can
be configured to notify administrators or other designated individuals
when ScanMail
takes actions against detected threats.
-
For a quick analysis of the security incident, view the ScanMail
Summary screen or create a one-time report. For
more detailed information about the security incident, query ScanMail
logs.
-
-
Manually update components to immediately download the latest ScanMail
components.
-
Follow-up the update with a manual scan of the entire information store.
Use the Trend Micro
recommended defaults such as IntelliScan and AntimalwareScanCore or set even
more aggressive scanning filters. If you know exactly what you are
scanning for, select Specified files from the
Security Risk Scan screen and type the name of
the file for ScanMail to detect.
-
-
Perform a Log Query to discover information about the attack. The log
contains such useful information as the time and date, sender and
receiver, and infected attachment names.
-
If you need assistance to help analyze the security problem, send your
virus/malware case to the Trend Micro Virus Response Service.
