Operating Systems and Browser

Keeping your computer updated and patched will provide an additional layer of security for your system, and your personal data.  Using out-of-date or defective software can leave your computer open to infection or attack, so it is essential to be vigilant in the update process.

Each computer runs on a specific operating system (OS) that houses the vital components that allows your computer to work.  The three most well-known operating systems are Windows XP and Vista, Macintosh OS X and Linux.  Much like the specific programs your computer runs, online criminals and hackers launch specific attacks against computer operating systems for personal gain. 

In order to keep step with these types of attacks, OS manufacturers issue regular updates (or “patches”) that fix specific problems or vulnerabilities in the OS.  These updates are primarily “pushed” to the computer user, meaning the computer automatically receives and downloads those fixes. 

Here are links to the update pages for the major OS vendors:

Similarly, hackers are looking for new ways to exploit users of older and out-of-date web browsers.  They can use un-fixed vulnerabilities or problems in a web browser to gather personal information, install malicious software (malware) and launch attacks against other machines.  Most of the major browser vendors regularly update their software to reduce risk factors, but much like Operating System updating – you should make sure you’re receiving the latest updates, running the most current version of your browser, and making sure you have all the proper security controls turned on.

Here are links to resources that will help ensure you are running the most current version of your browser:
