To protect your device from cyber-attacks, there are several steps you can take:

1. Install a Firewall: Firewalls provide a line of defense against malicious software entering your device, as it blocks incoming requests from sources you don't trust.
2. Install antivirus software: Antivirus software helps prevent malicious software from infecting your device, as it searches your device for potential threats and removes them before they can cause any damage.
3. Keep your device and software up to date: Regularly install updates and security patches to keep your device and the software that runs on it up to date.
4. Backup your data and information: Regularly back up your device so that you can restore important data and information, in cases of catastrophic software corruption or physical device damage.
5. Practice safe email, messaging and browsing habits: Be careful of what you type in online for communications, don't open emails from sources you don't recognize, and only visit sites you trust.
