Tips for safe Internet browsing

Exploiting browser vulnerabilities has become a popular way to compromise computers.There are several easy ways to secure your preferred browser, through individual browser settings and add-ons. Browsers aim for a balance of performance and security. Features added by the manufacturer to improve performance may make the browser (and the computer) less secure. In addition, the more add-ons you have installed, the more your browsing experience may be impacted or slowed.

Best Practices

  1. Install and use an ad blocker such as AdBlock Plus or uBlock Origin (for Chrome or Firefox).  It's best to use one or the other not both.
  2. Do not use the "remember my password" function of a browser or website. Instead, use the LastPass password management service (premium version available free to all Duke faculty, staff and students). Download LastPass install it and create an account, the activate the premium version available at Duke's LastPass page.  To remove data that may have already been saved see:  Chrome and Firefox.
  3. Ensure the pop-up blocker in your browser is enabled (instructions available for Chrome and Firefox).
  4. Consider private browsing using Chrome Incognito mode or Firefox private browsing. These options are starting to be available for mobile browsers as well. Firefox has created Focus as a privacy focused browser. 
  5. If you have Adobe Flash or Oracle Java plugins installed, consider uninstalling them. Many content providers have moved away from these platforms due to ongoing security issues with both. If you need Flash, it's built into Chrome. If something needs Oracle Java, remember it needs to be updated on a regular basis.  They continue to be two of the top programs leveraged by malware to compromise computers.
