14.5.2  Configuration example

Objective

:

Disable telnet. Generate new encryption keys. Use crypto-resistant algorithms.

Solution:

Disable remote telnet control:

esr(config)# no ip telnet server

Generate new encryption keys:

esr-

14.6  Configuration of protection against network attacks mechanisms

The algorithms for configuring the network attack protection mechanisms are described in the 

Logging and 

network protection configuration

 section of this manual.

For detailed information about the commands to configure the password policy, see 

Management of logging 

and protection against network attacks

 in the CLI Command Reference.

14.6.1  Recommendations

It is recommended to always enable protection against ip spoofing.
