Avoid Ad-hoc wireless networks

Disable automatic connection to any new networks and limit your connections to access point (infrastructure) networks only:
  • Click the "Start" button and navigate to the "Control Panel" and then to "Network Connections."
  • Right mouse-click on the "Wireless Network Connection" and choose "Properties".
  • Pick the "Wireless Networks" tab, then the "Advanced" button:
    • Make sure that the check box next to "automatically connect to non-preferred networks" is not checked.
    • Click on Access point (infrastructure) networks only to avoid ad hoc networks.

This configuration prevents you from automatically connecting to any new networks and refuses all ad-hoc networks, which have the potential to monitor traffic that passes through them.

Never respond to an email asking for personal information

Companies you do business with should never ask for account information, credit card numbers or PIN information in an email message. If you have any questions about an email you receive that supposedly comes from your financial institution, call the local branch office. Do NOT respond to the email.

Avoid spam in your IM email account

Did you ever sign up with an Instant Messenger client so that you could chat with your buddies? Perhaps you have more than one running on the desktop. Each popular IM client comes conveniently with an Email account, and each time there is an email associated with your IM screen name, you receive a notice with this account filling up. You can prevent the spam or any email notices from appearing by using a single filter. Since I added the following filter on my email account attached to my Yahoo IM, I no longer get these notifications. Simply add a filter that the From/ Address includes @ to go directly to trash. You will be able to communicate with all your IM buddies without the hassle of being notified of items coming into the inbox.

Paper files Have to Be Protected Too

You've probably heard that To err is human, but to foul things up completely you need a computer. We know it's important to protect the big databases that we store, but we can't ignore paper records. The amount of information held on paper may be much smaller, but many of the most serious leaks happen through very human methods — reports stolen from desktops or read over someone's shoulder. Keep sensitive paper files locked away when they are not being used and don't read them in public places.

Lock your workstation before you leave your desk

Did you know there are keyboard shortcuts other than CRTL+ALT+DEL that you can use to lock your desktop? This will prevent people from walking up and snooping on your computer. You can save a keystroke by simultaneously pressing the Windows key + L. The Windows key has four wavy squares.

Or, to make things even easier, create a desktop shortcut.
  1. Right click any empty area of your desktop
  2. Click New
  3. Click Shortcut
  4. Type in the following: rundll32.exe user32.dll, LockWorkStation
  5. Click Next
  6. Name your shortcut
  7. Click Finish

Now it's as easy as a double click!

Don't tell ANYONE your password

One way someone could learn your password is to phone you claiming to be from another part of your organization, maybe your IT or Audit teams, and say they need your account details to let them investigate problem. This should never be necessary. Good systems are set up so that nobody but you will ever know your password and authorized IT workers have their own accounts giving them access to what they need.

Passwords: Be creative


If you can't remember hard passwords no matter how hard you try, put your password in parenthesis. baseball38 is a weak password. (baseball38) is much better.

When you change your password, you should always change at least half of it and when you do, change the parentheses as well. Change the parentheses to asterisks, exclamation points or dollar signs. *sallyandbob39* is better than sallyandbob39, and !jimandbetty93! is better than jimandbetty93.

Do NOT open unknown or unexpected e-mail attachments

This morning I got an e-mail from my boss with an attachment. My boss is a man of few words on e-mail. If he wants to explain or discuss something with me, he picks up the phone. When he wants me to read or edit something we have talked about, he sends it to me. Even though the subject line was a date, the e-mail had no text, AND my boss hadn't told me he was sending me an attachment, I opened it because it was from my boss at an e-mail address I recognized. Bad move. Imagine my surprise when my Norton anti-virus screen popped up with a message that the attachment contained a virus and had been deleted. Hackers had spoofed his address and I had fallen for it.

Check and make sure your friend sent that great screen saver

A common method of transmitting malware is by infecting some unsuspecting user's computer and then using that computer to infect others. One simple way to do this is for a hacker to hijack your address book and send copies of the malware to everyone in that address book. Of course, YOU need to be enticed to run the malware, and the best way to do that is to fool you into thinking the attachment is something else. If a friend or acquaintance sends you a "great screensaver" or something like that, which you were not expecting, take a few minutes to confirm that person really sent it. If they know nothing about it, then delete the message.

Don't Accept Offers of "Free PC Scans" That Pop up When You Use the Internet


Secure Computers LLC paid a $1,000,000 fine for offering "free spyware scans" that told users their systems had been infected with spyware, even if the system was clean. They are not the only ones doing this — when you surf the Web you are still likely to see pop-up windows like that. Some "scans" don't just give misleading results; they actually try to install unwanted software on your PC. Often the screen pop-ups only have a "scan" button and no "cancel" or "quit" option. In fact they could interfere with your PC no matter which of the buttons you choose. Be safe: close pop-ups like this by clicking on the X in the top right corner of the browser window. Better yet, use a pop-up blocker software (http://www.vnunet.com/vnunet/news/2170208/security-firm-pay-million-false).

How to spot a phishing email...

How to spot a phishing email...

It could be a phishing email if...
  • There are misspelled words in the e-mail or it contains poor grammar.
  • The message is asking for personally identifiable information, such as credit card numbers, account numbers, passwords, PINs or Social Security Numbers.
  • There are "threats" or alarming statements that create a sense of urgency. For example: "Your account will be locked until we hear from you" or "We have noticed activity on your account from a foreign IP address."
  • The domain name in the message isn't the one you're used to seeing. It's usually close to the real domain name but not exact. For example:
