Event Monitoring provides a more generic approach to
protecting against unauthorized software and malware attacks. It monitors system areas
for
certain events, allowing administrators to regulate programs that trigger such events.
Use Event
Monitoring if you have specific system protection requirements that are above and
beyond what is
provided by Malware Behavior Blocking.
The following table provides a list of monitored system
events.
Monitored System Events
|
Events
|
Description
|
|
AI App Guard
|
Configure this policy to protect AI-integrated applications and related files from
malicious modifications.
|
|
Duplicated System File
|
Many malicious programs create copies of themselves or other
malicious programs using file names used by Windows system files. This is typically
done to
override or replace system files, avoid detection, or discourage users from deleting
the
malicious files.
|
|
Hosts File Modification
|
The Hosts file matches domain names with IP addresses. Many
malicious programs modify the Hosts file so that the web browser is redirected to
infected,
non-existent, or fake websites.
|
|
Suspicious Behavior
|
Suspicious behavior can be a specific action or a series of
actions that is rarely carried out by legitimate programs. Programs exhibiting suspicious
behavior should be used with caution.
|
|
New Internet Explorer Plugin
|
Spyware/grayware programs often install unwanted Internet
Explorer plugins, including toolbars and Browser Helper Objects.
|
|
Internet Explorer Setting Modification
|
Malware programs may change Internet Explorer settings,
including the home page, trusted websites, proxy server settings, and menu extensions.
|
|
Security Policy Modification
|
Modifications in Windows Security Policy can allow unwanted
applications to run and change system settings.
|
|
Program Library Injection
|
Many malicious programs configure Windows so that all applications
automatically load a program library (DLL). This allows the malicious routines in
the DLL to
run every time an application starts.
|
|
Shell Modification
|
Many malicious programs modify Windows shell settings to
associate themselves to certain file types. This routine allows malicious programs
to launch
automatically if users open the associated files in Windows Explorer. Changes to Windows
shell settings can also allow malicious programs to track the programs used and start
alongside legitimate applications.
|
|
New Service
|
Windows services are processes that have special functions and
typically run continuously in the background with full administrative access. Malicious
programs sometimes install themselves as services to stay hidden.
|
|
System File Modification
|
Certain Windows system files determine system behavior,
including startup programs and screen saver settings. Many malicious programs modify
system
files to launch automatically at startup and control system behavior.
|
|
Firewall Policy Modification
|
The Windows Firewall policy determines the applications that have
access to the network, the ports that are open for communication, and the IP addresses
that
can communicate with the computer. Many malicious programs modify the policy to allow
themselves to access to the network and the Internet.
|
|
System Process Modification
|
Many malicious programs perform various actions on built-in
Windows processes. These actions can include terminating or modifying running processes.
|
|
New Startup Program
|
Malicious applications usually add or modify autostart entries in the
Windows registry to automatically launch every time the computer starts.
|
When
Event Monitoring detects a monitored system event, it performs the action configured
for the
event.
The following table lists possible actions that
administrators can take on monitored system events.
Actions on Monitored System Events
|
Action
|
Description
|
||
|
Assess
|
The Security Agent always allows programs associated with an event to run
and logs the event for assessment.
This is the default action for all monitored system
events.
|
||
|
Allow
|
The Security Agent always allows programs associated with an event to
run.
|
||
|
Ask when necessary
|
The Security Agent prompts users to allow or deny programs associated with
an event from running and adds the programs to the exception list
If the user does not respond within a certain time period, the
Security Agent
automatically allows the program to run. The default time period is 30 seconds.
|
||
|
Deny
|
The Security Agent always blocks programs associated with an event from
running and logs the event.
After blocking a program with notifications enabled, the Security Agent
displays a notification on the endpoint.
