Proactive cyber defense is like putting on armor before going into battle. It means taking steps to protect yourself and your computer before bad guys try to attack you.
Just like putting on armor, proactive cyber defense means setting up tools and rules that can detect and stop attacks before they do any damage. Some examples of proactive cyber defense include firewalls and antivirus software that can block hackers and viruses from getting into your computer, and making sure you use strong passwords to protect your accounts.
Proactive cyber defense is important because it can help prevent cyber attacks from happening in the first place, which can save you a lot of trouble and keep your personal information safe.
