Section 4.4.4

Authentication Related Security Alarms

The following describes the authentication-related security messages that can be generated by ROS:
•

Section 4.4.4.1, “Security Alarms for Login Authentication”

•

Section 4.4.4.2, “Security Messages for Port Authentication”

Section 4.4.4.1

Security Alarms for Login Authentication

ROS provides various logging options related to login authentication. A user can log into a ROS device in three

different ways: Console, SSH or Telnet. ROS can log messages in the syslog, send a trap to notify an SNMP

manager, and/or raise an alarm when a successful and unsuccessful login event occurs. In addition, when a

weak password is configured on a unit or when the primary authentication server for or RADIUS is not

reachable, ROS will raise alarms, send SNMP traps and log messages in the syslog.
The following is a list of log and alarm messages related to user authentication:
• Weak Password Configured
• Login and Logout Information
• Excessive Failed Login Attempts
• RADIUS Server Unreachable
• TACACS Server Unreachable
• TACACS Response Invalid
• SNMP Authentication Failure

NOTE

All alarms and log messages related to login authentication are configurable. For more information

about configuring alarms, refer to 

Section 4.4.3, “Configuring an Alarm”

.

Weak Password Configured

ROS generates this alarm and logs a message in the syslog when a weak password is configured in the

Passwords

 table.
