Time for better password security
This article is one I’m writing in preparation for my next Tim’s Tech Tips (T3) video for work, and it’ll be posted in the Tech section of whlt.com when the video goes up. As a gift of sorts to everyone, I’m posting the article here first! ![]()
Password security is often something that you hear computer talking heads mention ad nauseum, but it’s rarely used correctly if at all. Here are simple and practical tips and resources for keeping your passwords secure.
I’m often reminded as I’m working with user accounts with all sorts of sites for my job that password security is incredibly important and yet equally incredibly overlooked. Sure everyone knows not to write down your passwords and stick them on your computer or monitor, but few know why, and even fewer know how to create truly safe passwords and how to retrieve them if they forget it.
Here’s my story: I use(d) three different passwords for all of my accounts, each one used for a different level of security. One simple one was for accounts that I really didn’t care if someone could break into, like newspaper sites or social networking sites. Another was for where I was making credit card transactions or similar sensitive but non-mission critical info. The final, and most complicated password(but sadly not complicated enough to not be hack-able) was for my online bank accounts and credit card sites. I made a lot of mistakes in creating my passwords that even someone like myself who deals with computers on a daily basis and knows all the horror stories should avoid. In the process of researching T3 episode #3 I’ve decided to start putting into practice better password security, and have already switched out some pretty easy-to-crack passwords for much more robust ones.
Following these tips are a full list of the resources I’ve looked at; the tips use the mnemonic “SECURE”:
- Secure passwords should never be an afterthought. Just like you would never consider a locking doorknob and deadbolt on your exterior house doors an afterthought, don’t treat making your passwords secure and “uncrack-able” as an afterthought. Your login information is literally like your front door: if the password(“doorknob”) is weak, then your information(“personal belongings”) are vulnerable.
- Every account should have a different password. While every password doesn’t necessarily have to “uber-secure”, every password should be different. The reason why is because if a hacker is able to access one of your accounts using a simple password the mindset you’re showing him is that you’ve likely protected other accounts with the same password. One of the biggest mistakes people make is using the same password, even if it’s a very secure password for multiple accounts. If you use the same password for some or all of your accounts, you might as well just hand the hacker a key to your house.
- Change your password with some frequency. The IT policy at your job may physically require you to change your work computer password at certain regular intervals (i.e. 30 or 90 days), but it’s doubtful that you have the same policies with your online logins or your logins at home. Set a specific and regular time to change all your passwords. One month is a short enough period of time to remember easily but long enough that you don’t feel like you’re always having to change your passwords. You can use programs like Microsoft Outlook and many others to remind you when it’s time to change your passwords for all your accounts. The reason for changing your passwords regularly is that it makes it that much harder for a hacker to discover the correct password within that period of time.
- Understand social engineering. There are three ways hackers discover your login information: brute force, dictionary hacks, and social engineering. The last one, social engineering, is basically when the hacker either physically gets on your computer and grabs your password information(a very good reason to hit “Windows Key + L” whenever you walk away from your password-protected computer to lock it while you’re away), or he will pose as some trustworthy source like your ISP or credit card company. This is also called “phishing” when it applies to emails or websites that are designed to take your login information illegally.
- Resist writing down your passwords. Much like #4, this tip avoids the social engineering process that hackers use to gain your login information. And before you think you’re clever, saving your password text files with a different extension (i.e. changing a .txt file to .exe in an attempt to disguise the actual file) is NOT a safe way to hide your passwords on your computer. Hackers are smart people, and they’re going to have programs that are able to dive into the actual data and see that your supposed executable file is really a text file with your password information. This is similar to using a plastic hide-away rock to hide your spare door key. Think of these programs as the hacker using a metal detector to find the “rock” that the key is hidden inside.
- Educate yourself on security. While you don’t have to become an expert in the field of cryptography(literally, the field of creating code-words, to put it simply) it is important to have a basic knowledge of how passwords and authentication in general works, how hackers think, and what are some of the best security programs. The end of this article features some resources I’ve found related to passwords themselves, but you can’t definitely use some of the sources on those sites to further your education. Before you complain about how difficult you think it might be, remember that you know the importance of having a safe home including solid door locks, having a neighbor watch your house while you’re away, and/or having a home security system installed in your house. Treat your login information with the same degree of caution and concern.
There are good programs that exist that can be used to securely store your login information and/or create secure passwords. One I use is SignUpShield Passwords. It is able to store passwords for most of the websites you’ll use. Some websites are designed in such a way that the program simply isn’t able to save your login information though, but this is very rare. On top of that, the entire program is protected with a master password. You can also use it on a U3-enabled flash drive, which you can find out a little more about in T3 episode #1.
For creating secure and random passwords, I use a page at Gibson Research Corp.’s website. PCTools also has a page that offers free secure passwords. Obviously they want to try to sell you their software, which I haven’t used so I can’t recommend for or against its quality. It generates a completely new “pseudo-random” password string every time you load/reload the page, and goes into detail on how the process works. It explains it in simple layman’s terms and in more technical terms if you’re interested. There are also some sites that offer free password security level checks, that use certain rules to determine whether your password is really as strong as you think it is. Here’s one hosted by The University of Chicago and another.
