CHAPTER 2. HOW DO I USE WEBHOST MANAGER?
The Security area deals with security issues, from scanning for security beaches and Trojan Horses to
modifying Apache's memory usage limit.
Running a quick security scan
WebHost Manager can perform a quick security scan of your server that attempts, in test mode, to shut
down various essential services. If any of these tests succeed, there has been a security breach of your server.
You may see [FAILED] next to one or more tests when you run the scan. This usually indicates
that the service was shut down normally prior to the scan, and does not normally indicate that there has
been a security breach.
To run a quick security scan:
1. Click on the Quick Security Scan link in the Security menu.
2. A list of results is now displayed.

Modifying Apache memory usage limit
WebHost Manager includes a function that automatically calculates the memory limit needed by Apache
and resets the memory used by Apache to that amount. This frees up your memory for other operations,
and is useful on busy or full servers.
To modify the Apache memory usage amount:
1. Click on the Modify Apache Memory Usage Limit link in the Security menu.
2. A result list is now displayed.

Scanning for Trojan Horses
WebHost Manager includes a function that enables you to scan your server for Trojan Horses. A Trojan
Horse is a malicious, security breaking program that is disguised as something benign, such as a directory
lister, archiver, or game. Like all viruses Trojan Horses can hide inside files for long periods of time.
