An important aspect of protecting a system is the concept of “defense in depth,” or having multiple layers of security without using one approach or technology to block all attacks. Here are some links to tools and approaches that I find useful for preventing malware from entering your computer. Your mileage may vary.

Learn, memorize and practice 3 rules

Follow the three basic rules of Internet security and you will greatly reduce the chances of transferring control of your computer bad guys. In short: 1) If you haven’t searched, don’t install. 2) If you installed it, please update. 3) When you no longer need it, take it out! For more information on these rules, see this blog post.

Stay tuned for updates!

It shouldn’t be, but the truth is that moreMost of the software requires regular updates. Therefore, keeping an eye on the latest security updates can sometimes be a tedious task. Not all software includes automatic update features that notify you when new fixes are available. If so, many of them are in no rush. Fortunately, there are tools to help you know when security updates are available. Secunia’s personal software inspector is a popular option. Another reason is the File Hippo update checker. Both are free.

Grab JavaScript Attention

Most websites use JavaScript, a powerful scripting language that can be used to make websites interactive. Unfortunately, most web attacks use JavaScript tricks to deliver malware and exploits to website visitors. To protect yourself, it’s important to be able to easily choose which websites are allowed to run JavaScript in your browser.

It is true that selectively allowing JavaScript on well-known and “safe” websites does not block alle Malicious Scripting Attacks: Even legitimate websites sometimes run malicious code when scammers figure out how to place fake ads and get corrupted mostly. Advertising networks on the Internet. However, disabling JavaScript by default and selectively enabling JavaScript for certain websites remains a much safer option than always running all websites without restriction using JavaScript.

Firefox has many browser extensions and add-ons. safer internet experience. One extension that I find important is NoScript. This extension allows the user to decide on which websites to run JavaScript, including Flash Player content. Users can allow certain exceptions permanently or for a single browser session.

Chrome also includes similar scripting and Flash blocking features designed to minimize some of these issues with fewer options. If you tell Chrome to block JavaScript on all websites by default, you areCheck the box with a red cross in the upper right corner of your browser when you visit a website that uses JavaScript. Clicking on it and selecting “Always enable JavaScript on [site name]” will permanently enable JavaScript for this site, but you will not be able to block third-party JavaScript content on the site like Noscript does. In my testing, I had to manually refresh the page before Chrome would allow scripts on the website I just whitelisted.

Also, there is a very handy ScriptSafe add-on for Chrome that works very much like Noscript. Please note that Java and Javascript are two very different things. Java is a popular and quite powerful software package that requires frequent and thorough security fixes. It connects directly to the browser and is a popular target for malware and thieves. NotScripts and NoScript block standard execution of Java applets. However, if Java is installed, you must either disable it from your browser or uninstall it. Readers don’t need to search this blog for examples of why I recommend this, but here’s one.

Internet Explorer allows you toUsers can block scripts, but even the latest version of IE doesn’t provide the user with a wide variety of JavaScript handling options. In IE9, you can choose between JavaScript enabled, disabled, or prompts to load JavaScript. Disabling JavaScript is bad, but leaving it completely unsafe is unsafe. If you select the Hint option, you will only see continuous tooltips allowing or denying scripts (see video below). The lack of an easier approach to blocking scripts in Internet Explorer is one of the main reasons I continue to recommend Firefox and Chrome to readers.

Microsoft EMET

EMET, short for Enhanced Mitigation Experience Toolkit, is a free tool from Microsoft that Windows users can use to improve the security of commonly used applications, whether they were created by third parties or Microsoft. With EMET, users can force applications to use one or both of the most important security measures built into Windows Vista and Windows 7 – ASLR (Address Space Randomization) and DEP (Security Prevention).increase data execution).

Simply put, DEP is designed to make it harder to exploit security vulnerabilities in Windows, while ASLR makes it difficult for exploits and malware to find specific locations in system memory where they are located. must work.

EMET can force individual applications to run ASLR for each loaded component, whether the program likes it or not. Please note that Microsoft .NET platform must be installed before installing EMET. While this technically works on Windows XP (Service Pack 3 only), XP users cannot take advantage of Mandatory ASLR and some of the other notable protections included in this tool.

To continue working with EMET, download and install the program. To wrap EMET protection around a program, for example. B. Internet Explorer, launch EMET and click the “Configure Applications” button in the lower right corner of the application window. In the next field, click the Add button to display the program selection prompt. Go to C: Program Files Internet Explorer, then add the IExplore.exe file. You can pr Take the default values ​​that EMET will add for you.

While you are working, add the rest of the most frequently used applications connected to the Internet. But do it slowly and avoid the temptation to make system-wide changes. General modification of system standards, for example. For example, changing the ASLR and DEP settings using the Customize System tab may cause stability and startup issues. I used it on a 64-bit Windows 7 system and gradually tweaked some of my most used apps one by one using the Configure Apps button to make sure the extra security doesn’t ensure programs don’t crash. So far, the only problem I’ve run into has been with Skype, which apparently wasn’t forced to use the six different defaults that EMET uses by default when you manually add an app: it just crashed on launch. The Microsoft support forum has a helpful thread discussing applications that may not work with the default EMET security settingsaniyu.

Save your passwords

Here are some tips for creating strong passwords. Take a moment to review them and consider updating some passwords if they aren’t enough.

If your email provider offers 2-Step Verification, use it. Gmail is one of the few companies that offers this extra layer of security and offers users several ways to get additional sign-in codes. You can find more information about this service in this article. Facebook also offers a kind of two-step verification.

Also, don’t forget to add a backup email account if supported by your email provider. If possible, also use two-step verification for this additional account. Here’s a warning about what can happen if you forget to add a backup email address or take full advantage of two-step verification.

Power up your equipment
