Recovering the Password
2.
Log in to the sensor with the default user ID and password—
cisco
.
Note
You are prompted to change the
cisco
password.
3.
Initialize the sensor.
4.
Upgrade the sensor to the IPS software version it had when the configuration was last saved and
copied.
Warning
Trying to copy the saved configuration without getting the sensor back to the same IPS software
version it had before the disaster can cause configuration errors.
5.
Copy the last saved configuration to the sensor.
6.
Update clients to use the new key and certificate of the sensor. Reimaging changes the sensor SSH
keys and HTTPS certificate, so you must add the hosts back to the SSN known hosts list.
7.
Create previous users.

Recovering the Password
For most IPS platforms, you can now recover the password on the sensor rather than using the service
account or reimaging the sensor. This section describes how to recover the password for the various IPS
