Cyber Security Tip: Computer Security

Why Should I Care About Computer Security?

Computers help us maintain our financial, social, and professional relationships. We use them for banking and bill paying, online shopping, connecting with our friends and family through email and social networking sites, researching data posted on the Internet, and so much more. We rely heavily on our computers to provide these services, yet we sometimes overlook our need to secure them. Because our computers play such critical roles in our lives, and we input and view so much personally identifiable information (PII) on them, it’s imperative to maintain computer security that ensures the safe processing and storage of our information.

How Do I Improve the Security of My Home Computer?

Following are important steps you should consider to make your home computer more secure. While no individual step will eliminate your risk, together these defense-in-depth practices will make your home computer’s defense stronger and minimize the threat of malicious exploit.

  • Connect to a Secure Network
    Once your computer is connected to the Internet, it’s also connected to millions of other computers, which could allow attackers access to your computer. Information flows from the Internet to your home network by first coming into your modem, then into your router and finally into your computer. Although cable modem, digital subscriber line (DSL), and internet service providers (ISP) purport some level of security monitoring, it’s crucial to secure your router—the first securable device that receives information from the Internet. Be sure to secure it before you connect to the Internet to improve your computer’s security. (See Securing Your Home Network for more information.)
