CHAPTER 2. HOW DO I USE WEBHOST MANAGER?

2.18

Security

The Security area deals with security issues, from scanning for security beaches and Trojan Horses to modifying

Apache's memory usage limit.

2.18.1

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. Note:

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.

2.18.2

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 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.

2.18.3

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. Note:

All files found

during this search are only suspected Trojan Horses. This scan only denotes the possibility of a virus in the file.

To scan for Trojan Horses:

1. Click on the Scan for Trojan Horses link in the Security menu.

2. A results list is now displayed.
