Oracle Fusion Middleware Deployment Planning Guide for Oracle Directory Server Enterprise Edition

Designing Access Control With Connection Rules

Connection rules enable you to prevent selected clients from establishing connections to Directory Server. The purpose of connection rules is to prevent a denial-of-service attack caused by malicious or poorly designed clients that connect to Directory Server and flood the server with requests.

Connection rules are established at the TCP level by defining TCP wrappers. For more information about TCP wrappers, see Client-Host Access Control Through TCP Wrapping in Oracle Fusion Middleware Administration Guide for Oracle Directory Server Enterprise Edition.
