Turn off the message preview pane in Outlook or Outlook Express
If the message preview pane is enabled, the messages in your inbox are automatically "opened" as you scroll through them. While this is convenient, it also poses a potential security risk. If you disable the preview pane, you can delete any email that looks suspicious BEFORE it's opened and avoid a possible virus infection.

Use variations on a strong "core" password
It's tough to remember a series of strong passwords and use a different one for each online system or site you access. The temptation is to use the same password for several or all systems and sites. That's a bad idea -- if a Bad Guy gets a hold of your password, he'll have the key that fits all of your doors. Instead, create a strong "core" password and then unique variations on it for each online system or site system you use. Here's a strong password: 5P0ky!3Z. It contains 8 characters, a mixture of uppercase and lowercase letters, at least one number and one non-alphanumeric character or symbol, and no personally identifiable information. By adding a character or two at the beginning or the end, you can have many variations to use for each system or site -- effectively creating a new strong password for each one. Remember to change your "core" password and its variations on a regular basis.

People Forget, Computers Don't
In 2003, the British Government published a report on Iraq's security and intelligence organizations. Then a Cambridge University lecturer discovered that much of the document was copied from three different articles, one written by a graduate student. How did he know? The document contained a listing of the last 10 edits, even showing the names of the people who worked on the file.
Hidden data can often be found within Microsoft Office documents particularly Word. Whenever you exchange documents with clients, either convert them to PDF format (WYSIWYG) or else run them through Microsoft's Hidden Data Removal tool.
... Lock your computer by holding down the "Windows" key and pressing the "L" key.

Don't enter your password on an untrusted computer.
A password is only as secure as the computer or network it is used on.
Bad Guys target public kiosk-type computers and wireless networks, such as those in Internet cafes, conference centers, hotels and motels, and airports. The instant you type your password on a computer that is infected or rigged, or on one using a compromised wireless network, the Bad Guy has got that password for good. This is one reason why you should change your passwords on a schedule, and never reuse a password on several computers or systems. Regard all public-use computers as untrustworthy. If you have no choice but to use a public computer, change your password before you log off or at the next available opportunity.

Don't download files from unknown sources
Not all web sites are safe. Always ensure that the source you are downloading from is legitimate. Use extreme caution if you are referred to a site by an email message. If you're uncertain, don't download.

Beware of Shoulder Surfing
A person who is standing near as you fill out a form, enter your PIN number, or punch in your calling card numbers may be doing more than just waiting their turn. To help prevent shoulder surfing, shield your paperwork from view using your body and cup your hand over the keypad.

Take time to explore security settings
Whether it is financial management software, instant messaging or a social networking website, take the time to see what security settings are offered to protect you and your information. Follow these steps for all of the software you use, not just email.
Go to Options or Preferences
Every program is different, so look for words like "Privacy", "Safety" or "Security" and click on them.
Select the most restrictive option (i.e. only let the people you approve view your information or contact you — or the one that best accommodates your business needs).
Save the settings.

E-mail is insecure by default because it is more like a postcard, not a sealed envelope
A number of people are under the misconception that when they draft and send e-mail, two things occur. Their message gets sealed in an envelope (that's why you have to open e-mail right?) and that it goes directly to the person it was sent to via internet magic. The truth is your e-mail is sent in plain text (i.e. readable by anyone who picks it up along the way) and is passed around the Internet with multiple stops until it reaches its destination. People with evil intentions can intercept your e-mail, read it or even alter it before it reaches your intended recipient.

Beware of USB flash drive's autoplay feature
A white hat hacker broke into a bank and left 20 USB tokens lying around the parking lot of the bank for employees to find. When they plugged in the USB token, the Trojan backdoor was installed on the employees' computers and the hacker was into the banks network! Some employees claimed they were being helpful — trying to find the token's owner, others were curious about the token's content, still others thought they had scored a huge USB token and tried unsuccessfully to reformat the token. Unfortunately the new "U3 Technology" on these tokens prevented a hidden partition from being deleted, and it contained a remote access Trojan which installed itself by emulating a cdrom and using WinXP's Cdrom autoplay feature.

Don't Trust Links Sent in Email Messages
A common fraud, called "phishing", sends messages that appear to be from a bank, shop or auction, giving a link to a fake website and asking you to follow that link and confirm your account details. The fraudsters then use your account details to buy stuff or transfer money out of the account. These fake sites can be hard to spot, so no reputable organization will send a message requesting your confidential information.

Keep your password secret
Your password is like your bank account PIN - if you give your PIN to someone else, your bank is unlikely to pay you back if it is used to steal from your account. Likewise, your company expects you to use your password to stop others misusing your computer account. If you share your password, you may be held responsible for what other people do with it.
Your most important files can be protected with a password. For example, in Microsoft Word, you can create a password to open and a password to modify a file. Just go to Tools | Options and click the Security tab. Remember the password so you don't lock yourself out!

Wireless Hotspots...limit activity to web surfing only
A hotspot is an open wireless network that is available (open) to everyone. An example would be the wireless network at your favorite coffee shop. These networks hook computers into the public Internet — handy but dangerous. Because wireless hotspots are for open use, they don't provide much protection for your data. When using a wireless hotspot try to limit activity to web surfing only. You should also disable peer-to-peer networking, file sharing, and remote access. Always use a good personal firewall and of course make sure all your software including your operating system (like Windows) is up to date and patched. You should never use hotspots for online banking, bill paying, or for making purchases that require you to give out confidential information such as a credit card number.

Effectively delete files
When you delete a file, depending on your operating system and your settings, the file may be transferred to your trash or recycle bin. This "holding area" essentially protects you from yourself—if you accidentally delete a file, you can easily restore it. An unauthorized person will also be able to retrieve it. Does your recycle bin include credit card information, passwords, medical, or other personal data? Is there sensitive corporate information? Empty the trash or recycle bin on a regular basis to ensure that deleted information stays deleted.

Just because your company's spam filter, virus filter and other defenses let an email through, doesn't mean it's harmless
Last year, one organization narrowly avoided a virus infestation. Alerts led them to the email in-boxes of the virus authors. To sneak in a virus, hackers used encrypted zip files, which went past filters because they couldn't be scanned. The organization caught it with the very last line of defense — desktop antivirus software, which triggered after the users had plugged in the password to see the zip file contents! Had the bad guys written something new, instead of using off-the-shelf script kiddie code that was in standard pattern files, there could have been a major outbreak. Long story short: End-user awareness about email and attachments is every bit as important as antivirus filters and firewalls. EVERY USER is an important part of hacker defense!

Think twice before you post personal information. Remember, even crooks may see what you post on social media sites
Criminals are mopping up because social media users are willing to share personal information about themselves and others. This data can be used to guess your password, give them the answers to account security questions or send you email with malicious attachments that appear to be from someone you know.

Revoking security access isn't always enough
A California man has been arrested for interfering with computers at the California Independent System Operator (Cal-ISO) agency, which controls the state's power transmission lines and runs its energy trading markets. Even though Lonnie C. Denison's security access had been suspended at the request of his employer because of an employee dispute, he allegedly gained physical access to the facility with his card key. Once inside, Denison allegedly broke the glass protecting an emergency power cut-off station and pushed the button, causing much of the data center to shut down. Cal-ISO was unable to access the energy trading market, but the power transmission grid was unaffected.

Nobody from the Help Desk needs your password
While watching some scenarios in some videos on computer security, one of the audience members turned bright red. After the video, she confided in me that she had once received a call from "The Help Desk" saying that they needed her password to trouble-shoot a problem they were having backing up her files. She provided it. Fortunately, she thought about it and 5 minutes later called the help desk to confirm. The help desk staff immediately locked her account and had her drop by with ID so they could provide her with a new password.

If you get up from your computer, lock it!
"I sent an email to your boss letting him know what you really think of him". This Notepad message was on my screen when I got back to my cubicle after getting up to stretch my legs. What? I had been gone for 180 seconds -- three quick minutes. Lucky for me, the note turned out to be from our systems administrator who wanted to make a point. All it takes is about one minute for a disgruntled colleague to send a message on your behalf to the boss and there is no way for you to prove you didn't send it. In about 30 seconds, a cracker could install a keystroke logger to capture everything you type including company secrets, user names and passwords. In about 15 seconds, a passerby could delete all your documents.

Don't Click to Agree without Reading the Small Print
Some free software passes your information on to advertisers, changes your PC or downloads other software without asking you. Some suppliers will claim that this is OK because you agreed to this. How? People often click on the "agree" button to accept 20 pages of difficult legal jargon they don't understand. But buried in the middle can be a sentence allowing the software to do whatever it likes. You can argue in court that the terms aren't reasonable, but then it will be too late — the damage has been done and your PC is broken. Learn from other people's pain: if terms and conditions are hard to understand, it is probably deliberate. If it isn't worth the trouble to read the conditions, don't risk using the software.

Better safe than sorry: If you're unsure that a file or program is clean, scan it for malware before you open or install it
Find out if a file or program of 10MB or less is free of malware by uploading it to www.virustotal.com, a free service which scans submissions using a combination of antivirus engines. VirusTotal detects viruses, worms, Trojans, and other kinds of malware that any one antivirus application might miss.

Use Outlook? Use the Auto-Preview, not the Reading Pane
If you are using an older version of Outlook, or if you have managed to reset the security level for e-mails, then you may be at some risk for HTML script-based exploits. Auto-Preview displays the first three lines of the message, enough to identify whether the message is valid, and it displays faster. Here is how to use it. Disable the Reading Pane and Enable Auto Preview:
Choose View -> Reading Pane -> Off
Choose View -> AutoPreview
Now you can see what is Junk, and which ones may have an HTML payload.

Email isn't the only online communication that has security risks
Instant Messaging has become a popular way for people to communicate over the Internet. In some instances it has even replaced email. What some people don't realize, however, is that instant messaging has many of the same security threats that email does... and then some. Instant messaging can transfer viruses and other malware, provide an access point for Trojans, and give hackers an easy way to find victims. If you use instant messaging on a regular basis, you need to be aware of the security risks associated with it and take steps to protect yourself. See the following links for more on instant messaging safety.
Most software and hardware setup procedures are designed to get the product up and running with maximum functionality and minimum effort. One thing that usually slips is security. If you set up your external firewall with the suggested password from the installation instructions, how many others are set up just like that? Take the time to change the defaults that will make the attacker's job just a little bit harder. Make sure to document the changes in a secure way.

Always lock your computer (by pressing CTRL + ALT + DELETE and hitting "Enter") before walking away from it
Locking your computer before leaving it unattended prevents anyone else from accessing it while you are away. This is especially important when there are customers in your office. Leaving your computer unlocked can expose customer data to a third party. Even when there is no one in your office, data could be exposed if your computer screen faces an outside window, especially on the ground floor.

It takes two to tango and two firewalls to secure your system
Contrary to the myth that hardware firewalls are better than software firewalls, both are equally necessary to secure your system because they provide different kinds of protection. Any size network — whether it's one or two computers on a home network or 100 computers in a business — needs to be protected by a hardware firewall, and every connected computer needs to be protected by a software firewall.

Save your files to a network server
A computer user working on a critical project was saving the analysis document on his Windows desktop. Unfortunately, the Windows desktop was located on the local hard drive and local hard drives were not automatically being backed up. When his hard disk failed, he lost the file and had to work through nights and a weekend to make up for the lost time. If your company permits network backups or remote storage, be sure you back up your important files. PS. Important files don't include things like vacation pictures, which can overburden the backup system. Ask the help desk for advice on where such files should be saved.

Don't plug in USB drives that you find lying around. Criminals can use them to steal your data
People's natural curiosity and desire to help were exploited by consultant Steve Stasiukonis, who was hired to check security awareness at a credit union. He loaded malicious software on old thumbnail drives and left the drives on the ground and tables in the parking lot and smoking areas. Each time a curious, helpful person plugged any of the thumb drives into his computer, it loaded software and reported who had taken the bait. His test was harmless, but criminals can use the same technique to take control of our computers.
