Patch, Patch, PATCH!
  An unpatched machine is more likely to have software vulnerabilities that can be exploited. Turn on automatic updates:

Install protective software.
Once installed, schedule software(Antivirus) to regularly scan and update your virus definitions automatically.

Choose strong passwords.
  Strong passwords use a combination of letters, numbers, and special characters. Create a unique password for each account.

Back up on a regular basis.
  Scheduling routine backups can protect you from the unexpected. Always keep a few months' worth of retrievable backup.

Control access to your machine.
  Don't leave your computer in an unsecured, public area, especially if you're logged on.

The physical security of your machine is just as important as its technical security.

       Use email and the internet safely.
Ignore unsolicited emails. Be suspicious of attachments, links, and forms in emails that come from people you don't know, or Avoid untrustworthy (often free) downloads.

       Use secure connections.
When connected to the internet, your data can be vulnerable while in transit. Use remote connectivity and secure file transfer options when off campus.

       Protect sensitive data.
Securely remove sensitive data files from your hard drive, especially when recycling or repurposing your computer. Protect sensitive files using the encryption tools built into your operating system.

       Use desktop firewalls.
Mac and Windows computers use basic desktop firewalls to protect your computer files from being scanned. Make sure they are properly configured.

       Most importantly, stay informed.
