Password Security for the End User
Although passwords are a central security mechanism, they can be fairly easy to crack or guess, but with only a few measures, users can help prevent this from occurring. Password parameters are frequently secured at the system level; however, this does not usually prevent the end user from creating a password that is fairly weak. With increased risks associated with password security, the need for end-user training is exceptionally necessary.
There are many different methods of cracking passwords; however, the most simple and common is using a word list or dictionary program to break the password using brute force. These programs use a word list or character combination and compare it against the password until they find a match. Additionally, a common method of acquiring a password is through social engineering. Social engineering is using social techniques, such as making a phone call to an end user impersonating a help desk technician or taking the written password off of someone’s desk, in order to obtain a password. There are many more methods of obtaining passwords, as well, yet these are the most efficient and easy.
How many of your end users use dictionary words with a number sequence as their password? Most likely, the majority. With a few minutes per year of end-user training, you could exponentially increase the security of your environment. Some of the most common security risks with passwords are caused by the end user; they include writing a password down, using a dictionary word, or using personal information. Take the time to educate your users. Follow this checklist in order to create a quick and useful training session and increase your system’s overall security:
- Do not use dictionary words, proper nouns, or foreign words within a password.
- Do not use personal information such as your dog’s name, child’s birth date, or town of residence within a password.
- For systems that have limitations to what password parameters can be set, educate the user to follow the desired length, complexity, etc.
- Educate users on ways to remember passwords, such as using the first letter of each word in a phrase they can remember.
- Educate users on common social engineering approaches and help prevent users from being fooled by fraudulent social activity.
