Today, we’ll be continuing our #NoHacked campaign. We’ll be focusing on how to protect your site from hacking and give you better insight into how some of these hacking campaigns work. You can follow along with #NoHacked on Twitterand Google+. We’ll also be wrapping up with a Google Hangout focused on security where you can ask our security experts questions.
We’re kicking off the campaign with some basic tips on how to keep your site safe on the web.
1. Strengthen your account security
Creating a password that’s difficult to guess or crack is essential to protecting your site. For example, your password might contain a mixture of letters, numbers, symbols, or be a passphrase. Password length is important. The longer your password, the harder it will be to guess. There are many resources on the web that can test how strong your password is. Testing a similar password to yours (never enter your actual password on other sites) can give you an idea of how strong your password is.
Also, it’s important to avoid reusing passwords across services. Attackers often try known username and password combinations obtained from leaked password lists or hacked services to compromise as many accounts as possible.
You should also turn on 2-Factor Authentication for accounts that offer this service. This can greatly increase your account’s security and protect you from a variety of account attacks. We’ll be talking more about the benefits of 2-Factor Authentication in two weeks.
2. Keep your site’s software updated
One of the most common ways for a hacker to compromise your site is through insecure software on your site. Be sure to periodically check your site for any outdated software, especially updates that patch security holes. If you use a web server like Apache, nginx or commercial web server software, make sure you keep your web server software patched. If you use a Content Management System (CMS) or any plug-ins or add-ons on your site, make sure to keep these tools updated with new releases. Also, sign up to the security announcement lists for your web server software and your CMS if you use one. Consider completely removing any add-ons or software that you don’t need on your website — aside from creating possible risks, they also might slow down the performance of your site.
3. Research how your hosting provider handles security issues
Your hosting provider’s policy for security and cleaning up hacked sites is in an important factor to consider when choosing a hosting provider. If you use a hosting provider, contact them to see if they offer on-demand support to clean up site-specific problems. You can also check online reviews to see if they have a track record of helping users with compromised sites clean up their hacked content.
If you control your own server or use Virtual Private Server (VPS) services, make sure that you’re prepared to handle any security issues that might arise. Server administration is very complex, and one of the core tasks of a server administrator is making sure your web server and content management software is patched and up to date. If you don’t have a compelling reason to do your own server administration, you might find it well worth your while to see if your hosting provider offers a managed services option.
4. Use Google tools to stay informed of potential hacked content on your site
It’s important to have tools that can help you proactively monitor your site.The sooner you can find out about a compromise, the sooner you can work on fixing your site.
We recommend you sign up for Search Console if you haven’t already. Search Console is Google’s way of communicating with you about issues on your site including if we have detected hacked content. You can also set up Google Alertson your site to notify you if there are any suspicious results for your site. For example, if you run a site selling pet accessories called http://www.example.com, you can set up an alert for [site:example.com cheap software] to alert you if any hacked content about cheap software suddenly starts appearing on your site. You can set up multiple alerts for your site for different spammy terms. If you’re unsure what spammy terms to use, you can use Google to search for common spammy terms.
We hope these tips will keep your site safe on the web. Be sure to follow our social campaigns and share any tips or tricks you might have about staying safe on the web with the #NoHacked hashtag.
If you have any additional questions, you can post in the Webmaster Help Forums where a community of webmasters can help answer your questions. You can also join our Hangout on Air about Security on August 26.
