string. Attackers can query a community to draw a very complete network map and possibly
modify management information base (MIB) values.
■
Always log out after using the system controller if the system controller uses a browser
interface.
■
Disable unnecessary network services, such as Transmission Control Protocol (TCP) or
Hypertext Transfer Protocol (HTTP). Enable necessary network services and configure
these services securely.
■
Create a banner message that appears at login to state that unauthorized access is prohibited.
You can inform users of any important policies or rules. The banner can be used to warn
users of special access restrictions for a given system, or to remind users of password
policies and appropriate use.
■
Use access control lists to apply restrictions, where appropriate.
■
Set time-outs for extended sessions and set privilege levels.
■
Use authentication, authorization, and accounting features for local and remote access to a
switch.
■
Use these services in very secure environments as they are secured by certificates and other
forms of strong encryption to protect the channel:
■
Active Directory
■
LDAP/SSL (Lightweight Directory Access Protocol/Secure Socket Layer)
■
Use these services on private, secure networks where there are no suspected malicious
users:
■
RADIUS (Remote Authentication Dial In User Service)
■
(Terminal Access Controller Access-Control System)
■
Use the port mirroring capability of the switch for intrusion detection system (IDS) access.
■
Implement port security to limit access based upon a MAC address. Disable auto-trunking
on all ports.

which is part of the Oracle ILOM documentation library. You can find the Oracle ILOM
