|
||
|
|
<p>The directory server protects against the following types of denial of
|
||
|
|
service attacks:</p>
|
||
|
|
<ul>
|
||
|
|
<li>Clients that send data slowly, send partial data, or send no data</li>
|
||
|
|
<li>Clients that do not read data results or who read results slowly</li>
|
||
|
|
<li>Clients that do not unbind</li>
|
||
|
|
<li>Clients that make requests that produce long-running database requests</li>
|
||
|
|
<li>Clients that bind anonymously</li>
|
||
|
|
<li>Server loads that prevent the administrator from administering the server</li></ul>
|
||
|
|
<p>The directory server gives an administrator several methods to prevent
|
||
|
|
denial of service attacks. An administrator always has access to the server
|
||
|
|
through the use of an emergency thread even if the server is busy with long-running
|
||
|
|
operations. In addition, the administrator has control over server access
|
||
|
|
including the ability to disconnect clients with a particular bind DN or IP
|
||
|
|
address and configure the server to not allow anonymous access. Other configuration
|
||
|
|
options can be activated to allow the server to actively prevent denial of
|
||
|
|
service attacks.</p>
