How can a CBS 250 Switch be protected against dictionary attacks?

If a device’s address is known, a malicious user might attempt a dictionary attack. This type of attack is an automated process that tries to log in by using thousands, or even millions, of different credentials. The goal of a dictionary attack is to gain management access to the device.

To prevent these attacks, the device can be configured to limit the number of login attempts allowed within a specific time frame and to define a quiet mode period after a certain number of failed attempts. If the specified number of connection attempts fails within a set time (in seconds), the device will block any additional login attempts for a specified period (block-for seconds). This can also happen if a user forgets their login credentials and tries to log in multiple times, resulting in login failure.
