Applications secured with authentication can be subject to brute force attacks that systematically try to guess user passwords. This application provides a protection mechanism that allows taking countermeasures against these attacks:

IP-level Attack

The attacker has a list of users and tries to guess their passwords from a specific IP address. In this case, the attacker IP address is blocked.
By blocking the IP address, the application won't also allow the attacker to go through all users and flood the application with requests, which could also lead to a denial-of-service (DoS) attack.

Mobile Phone Attack

The attack is perpetrated with the intention of autentication with the Mobile Phone. In this case, that mobile phone is blocked from accessing.
