Automatic IP Blocking Cybersecurity

Any computer system is best protected from outside access using a password at entry level itself. Only authorized users are allowed to use the system and its resources. Coming to network level, the security issues are high, a strong password is necessary for all web accessed services, such as for emails, database storage and so on. The most common and vulnerable attack for any computer network system is a brute force attack where, the password is being guessed by the hacker by using any password cracking tool. Once the password is obtained the attacker may or may not change the system files and its operations. Until the attack is discovered by the user, the attacker is using the information of the system in a passive way. Hence it can be termed under passive attacks. Detection of passive attacks is quite difficult since, there would be no traces of any alteration in the normal working of the system and its networks.
