Intruder Detection/Lockout<br />

By activating "Detect Intruders" unauthorised login attempts to the Novell<br />

Netware server will be recognised and the accounts concerned will be frozen,<br />

if need be.<br />

By activating "Detect Intruders" along with further parameterisation of this<br />

menu point, a "Brute Force Attack" under Novell Netware will be prevented.<br />

Incorrect Login Attempts indicates the number of permitted failed login<br />

attempts. Generally, the number "three" should be selected here.<br />

With the help of Bad Login Count Retention Time the time of the failed<br />

login attempts to an account can be traced back. If the number of failed login<br />

attempts exceeds the number set under Incorrect Login Attempts, within the<br />

time allowed, the user account will be frozen on the Novell Netware server.<br />

<strong>The</strong> menu item Lock Account After Detection should be set to "Yes", so that<br />

an account which exceeds the number of invalid login attempts is frozen.<br />

<strong>The</strong> time set for Length of Account Lockout should under no circumstances<br />

be too small (> 1 hour), to assure that the reason for an Intruder Lockout can<br />

be resolved by the System-administrator and the user concerned.<br />
