Understanding Cyber Security: Protecting Your Digital Life
Every day, you rely on the internet for work, shopping, banking, and socializing. But all this convenience comes with risks. Cyber security is the practice of defending your personal information, devices, and networks from malicious attacks, theft, and damage. As cyber threats rise, knowing the basics protects you and your data.
What Is Cyber Security?
Cyber security means using strategies, technologies, and best practices to secure computer systems and sensitive data from unauthorized access. These defenses target risks like malware, phishing, hacking, and data breaches. Cyber security covers everything from antivirus programs to risk management policies for businesses.
Key Cyber Security Terms You Should Know
