Having an Anti-Virus running on your computer, protecting your email from phishing attempts and choosing strong passwords are all good ways to keep your University Library computer safe.
Another way to keep your computer safe everyday is to make sure your screen is locked when you need to step away.
Locking your computer keeps your files safe while you are away from your computer. A locked computer hides and protects programs and documents and will allow only the person who locked the computer to unlock it again. You unlock your computer by logging in again (with your PSUID and password).
Locking Your Computer
- Press and hold the Windows logo key on your keyboard (this key should appear next to the Alt key), and then press the L key. Your computer will be locked, and the Windows 10 login screen will be displayed. On a Mac, you can press Command+Control+Q to lock your Mac.
Note: Any applications, files, Web pages, or other windows you opened before you locked your computer will remain open while your computer is locked.
This is especially true if you work in a public area of the Library. If you have an office, lock your office space. If you don’t, ALWAYS lock your computer when stepping away for any period of time.
Finally, University Libraries machines are set to lock after 15 minutes of inactivity. However, web browsers with videos playing will prevent screenlock. Please make sure you always lock the device yourself whenever possible when stepping away. Remember, you are responsible for your computer, whether you work in a public space, have an office or work at home.
