Defending Your Computer

There are several software products and settings you can make that will help alert you to or protect you from certain kinds of technology attacks such as malware, viruses, and so on.   Use these programs and keep them up to date so they can defend you against the latest threats.

Operating system and other software updates

When software companies discover security gaps in their software, they make updates available to fix them. Download these updates (commonly referred to as patches) on a regular basis.  If you use Microsoft Windows set up Windows Update (click Start/Control Panel/Check for Updates) to automatically check for and download the latest updates.

Firewalls

A firewall puts restrictions on what information can come through to your computer.  Don’t use the Internet without having a firewall turned on.  Depending on the settings you choose, a firewall will reject unsolicited requests coming to your computer, or will verify with you whether a request should be blocked or allowed.

Microsoft Windows offers built in firewall protection, as do some other operating systems.  Third party firewall programs include ZoneAlarm and Norton Personal Firewall.

Antivirus software

Computer viruses are small programs that can be downloaded to your computer and cause damage to your data or operating system.  People are coming up with new viruses every day, so it’s important that you use software that is up to date with the latest virus definitions and protects your computer from them.

Anti-spyware/anti-adware

Spyware and adware cause pop-up ads to appear on your screen or track your online activities. With the amount of spyware and adware attempting to download to your computer an anti-spyware/adware program is a must-have security tool.  If you don’t guard against these those annoying pop-ups will be the least of your problem. Eventually these programs will slow your computer performance down to a crawl.

There are several good free programs available, or use your operating system’s tools (such as Windows Defender).  You may need to purchase a subscription to get automatic updates.  As with antivirus software, you can set up anti-spyware/adware to run scans automatically at a present time increment.

Browser settings and filtering software

Many ISPs and Web portals provide safety settings, often called parental controls.  You can set these up to filter out content that you don’t wish to see based on keywords or categories of content (such as sexually explicit or violent content).  You can also use these programs to limit or monitor your child’s online activities.

If you don’t find your ISP’s tools adequate, you can search online for products that provide various levels of content monitoring.

How to protect your wireless network

If you set up a wireless router but did not set up security passwords or activate encryption, then chances are good that your network and your computer are not protected. But you can correct that fairly easily by following the instructions provided by Microsoft or Apple.

(Note: Once you secure your network, friends and guests who want to access your wireless network will have to get the password or key from you before they can go online.)

Once your wireless network is secure, check to be sure you have the latest antivirus, firewall, anti-spyware, and other security programs running and up to date.

Creating strong passwords

Safe passwords don’t have to be hard to create; they just have to be hard to guess.

The prospect of creating a strong password, changing a password or using multiple passwords makes many people anxious because they believe it requires memorizing multiple complex passwords such as Wts4e_79PBa13^_qnS.

The result is that people find the task so daunting that they continue to use one simple password. This just isn’t safe particularly if the password is a simple one. If that one password gets compromised, all of your Web information is compromised.

Some people use several passwords, but these passwords are short, simple words or include numbers that relate to their personal information (such as birth date or address) and so are easy to guess.

If you made hard-to-remember passwords you probably did so because your business or a Web site forced you. In this case, you are likely to have a list of the passwords next to your computer – even though you know this also compromises your safety.

What makes a strong password

There are some very easy rules of thumb you can use to make sure your passwords aren’t weak.

Weak passwords:

• Password – The word “Password” is the most commonly used password and it is pathetically weak – as are ‘default’ and ‘blank’. These are simple words and easily guessed or broken with a dictionary assault on the password.
• Smith1968 - Though this uses 9 characters and includes letters and numbers, names that are associated with you or your family, or uses other identifying information such as birth year, are easily hacked.
• F1avoR – Though it mixes up capitols and numbers, it is too short and substituting the number 1 for the letter l is easy to guess.

Strong passwords. It’s easy and can actually be fun to create strong passwords - you just have to know how - and the payoff in increased safety is huge. There are 5 principles when protecting passwords:

1. Length – use at least 10 characters
2. Strength – mix it up with capitals, characters, and numbers
3. Obscure – use nothing that is associated with you, your family, your company, etc.
4. Protect – do not place paper reminders near your computer
5. Change – the more sensitive the information, the more frequently you should change your password

Look at these examples of password patterns that are safe but also easy to remember.

Beware of simple password hints

Often, you are given a choice of password ‘hints’ when setting up a membership or an account. Security questions that someone can easily discover the answer to expose you to theft on the site involved, and allow the criminal to collect additional information about you. When given a choice, never pick a hint whose answer is easily discoverable.

When all the choices – as in this example - are easily discoverable, feel free to ignore the question and use an answer that means something to you; for example, sunshine. The site isn’t actually validating this information for accuracy; they just want you to provide the same answer that you used to establish the account. Enter whatever you want, but make it memorable.
