Final answer:
To restrict access to your files and devices, you should use strong passwords, enable two-factor authentication, update software regularly, avoid suspicious links, use anti-virus software, protect personal information, be aware of scams, and notify institutions of contact info changes.
Step-by-step explanation:
To restrict access to your files and devices, both personal and professional, you should do all of the following:

- Enable two-factor authentication, which adds an extra layer of security beyond just a password.
- Regularly update your software and devices to ensure that you have the latest security patches.
- Avoid clicking on suspicious links or downloading unknown files, to prevent malware and hacking attempts.
- Use anti-virus software on your computer to protect against malware and other threats.
- Protect your sensitive personal information by being mindful of how much information you share online and who you share it with.
- Be aware of scams and fraud, especially online, and take measures to safeguard your financial accounts like credit and debit cards, your wallet, and your mailbox.
- Notify your bank and other institutions when you change your address or phone number, to prevent your personal information from falling into the wrong hands.
By implementing these measures, you increase the security of your personal and professional data against unauthorized access and cyber threats.
