February 19th, Security Simplified: You have accounts on many different web sites. Some are small and relatively insignificant, from a security point of view, like blogs or shopping sites. Some are large and sensitive, like banking and PayPal accounts.
Since unified login mechanisms like OpenID are not yet pervasive, you must remember the usernames and passwords for every single site. This is a truly daunting task.
Typically, they will, among other things: Check the list of the most commonly used passwords. Perform a dictionary attack by trying every word in a dictionary. Finally, try the words with common numbers substituted for similar looking letters.
Perform another dictionary attack using all common first names and last names, possibly with varied capitalization of the first letters. You may be surprised to know that, depending upon the situation and security of the location where the password trying to be guessed is, that the malicious person may be able to try millions of guesses in a very short amount of time.
So, in many situations, trying these seemingly endless possibilities is really possible. So, a strong password is one that cannot be guessed using an automated program using any of these possibilities and which also cannot be guessed by someone who knows you well and tries passwords based upon information related to you.
This makes it hard to choose a password that you can remember and even harder to choose many different ones for many different web sites. Why use different passwords for different web sites? Simply put, if you have different passwords for every web site you have an account, if one of these accounts is compromised or stolen, that information cannot be used to login to any of your other accounts.
Using separate passwords is actually extremely important, because the possibility of one of your passwords being compromised or at least known by other people, is very very high. Many even most web sites keep a copy of your password to their site unencrypted and in plain text in their databases.
They do this either to facilitate verifying your password when you login a poor way to do this, but commonor so that they can give your password if you have lost it instead of forcing you to reset itor so that they can use that password for various things within their systems, like performing automated tasks for you.
However, as a result, your password is visible to their system operations staff, and possibly even their support staff. It is also visible to anyone else with access to their databases, such as a hacker that might break into their systems.
So, you should assume that the people who work for each web site know your username and password to that web site. If they can guess what other web sites you might be logging into, they could maliciously try that password and similar usernames or email addresses to gain access to accounts as you.
This is like writing your username and password on a postcard and sending it in the mail … anyone who can see the message being sent can read your sensitive information.
This is especially dangerous if you are connecting from a wireless hotspot or other location where you do not trust everyone who may be using the local network. If you login to a web site without SSL security, you should assume that some could get your username and password and login there as you, and that they could try to use that information to login to other sites as you too.
