Quick Tips

Please feel free to contact information security at security@commonwealthu.edu with any questions.

What follows are some obvious, and not so obvious, tips to help protect yourself and your data:

  • Don’t plug in random USB drives – they could carry malware that infects your device.

  • Lock your computer when you step away – someone could misuse your access in seconds.

  • Never leave your laptop or backpack unattended – thefts can happen fast, even in trusted spaces.

  • Avoid using public Wi-Fi without a VPN – your data can be intercepted.

  • Think before you click – phishing emails often look official. When in doubt, don’t click.

  • Enable multi-factor authentication (MFA) where ever possible– it adds a vital layer of protection to your accounts.

  • Keep software and apps updated – updates patch security holes.

  • Use strong, unique passwords for each account – and consider using a password manager.

  • Don’t share your login credentials – not with coworkers, friends, or anyone. 

  • Report anything suspicious – trust your gut and notify IT/security right away.

  • Beware of QR codes posted in public – attackers can replace them with malicious links.

  • Don’t reuse your university password on other sites – if one site gets breached, attackers try the same password elsewhere.

  • Cover your webcam when not in use – malware can silently activate it.

  • Don’t auto-forward your university email to personal accounts – sensitive data may leave secure systems.

  • Clear browser autofill on shared or lab machines – it can store passwords or personal info.

  • Avoid saving passwords in your browser – use a dedicated password manager instead.

  • Be cautious with browser extensions – some collect data or inject malicious code.

  • Log out of accounts on shared or public devices – closing the tab isn’t enough.

  • Check app permissions – many mobile apps ask for far more access than they need.

  • Don’t assume "cloud" means safe – always verify who has access and what protections are in place.
