Use Strong Passwords
While a firewall can protect from almost every attack by a hacker, this must be kept in mind that if a hacker is able to gain access to your computer by any chance, the firewall can be rendered useless. Let alone hackers, anyone can gain access to your sensitive data if they know your password. For example, if anyone wants to gain unauthorized access to your computer, he or she does not need breach your firewall; rather he or she can guess your password instead. That is why, it is essential that you use strong passwords that are unbreakable.
Creating a strong password basically requires the following things:
1. Length. If the password is short in length, this makes it easier for the hacker to guess the password by simply guessing it. Therefore, it is best to have a password of 6 to 8 characters. Longer passwords can quickly frustrate most hackers, even if they use password breaking tools.
2. Structure. Passwords consisting of combination of digits, characters and symbols provide the best security, even against powerful password breaking software. If you use a simple password instead like "applestreet", it will then become too easy for even the ones other than the hackers to guess it.
3. Uniqueness. Just as you do not have one key for your door, car, garage, etc, you should never use the same password for all your access codes. Using a commonly used password can be guessed by your friends and colleagues easily. And if they succeed in stealing your password, you can expect them to misuse your online bank account, email accounts.
4. Frequency. The best practice after creating a strong password is to change it regularly. You should change your password idly after every 3-4 weeks. Doing this will narrow the chances for someone who might have stolen your password to misuse it.
