Password Attacks

Password Protection
Passwords are undeniably a huge part of your online security. You'll find that almost every website that you visit that deals with online transactions, emailing and shopping use passwords to verify you. This means that you not only need to choose a password that cannot easily be figured out, but you should also keep it safe and secure and not share it with anyone. Do not use the same password for all of your accounts and attempt to come up with a password that contains letters, numbers, and special characters.

Password Attacks

A 'Password Attack' is a general term that describes a variety of techniques used to steal passwords to accounts.

Brute-force:- One of the most labor intensive and unsophisticated methods hackers use to steal passwords is to try to guess a password by repeatedly entering in new combinations of words and phrases compiled from a dictionary. This 'dictionary attack' can also be used to try to guess usernames as well, so developing difficult to guess usernames and passwords is increasingly vital to network security.

Packet sniffers:- Packet Sniffers glean data electronically from a compromised network.

IP-spoofing:- Similar to 'Honeypots', this attack involves the interception of data packets by a computer successfully pretending to be a trusted server/ resource.

Trojans:- Trojans are actually invasive and of these methods, are the most likely to be successful, especially if they install keyloggers.

Prevention
Automated testing (e.g., dictionary scanning), human behavior (e.g., lack of diversity in usernames and passwords), and other security flaws make it easier for password attackers to succeed. Unfortunately, there is no one single method to prevent against password attacks, though combining network traffic analysis along with the old stalwarts of email scanning, virus protection, firewalls and an educated work force can all together form a strong defense for any network.
