What Is Cybersecurity? Cybersecurity is the practice of protecting computers, networks, and data from unauthorized access, theft, or damage. It includes everything from strong passwords and secure Wi-Fi to advanced defense systems used by businesses and governments. In today’s connected world, cybersecurity is just as important as locking your front door. Why It Matters Every time we go online—whether it’s to send an email, post on social media, or shop—we leave behind digital footprints. Hackers and cybercriminals target this information to steal identities, spread viruses, or commit fraud. Cybersecurity helps keep our information safe and our digital world trustworthy. Common Cyber Threats - Phishing: Fake emails or messages that trick you into giving away personal information. - Malware: Harmful software that can damage or control your computer. - Ransomware: A type of malware that locks your files until a payment is made. - Social Engineering: When someone manipulates you into revealing confidential information. - Data Breaches: When sensitive data is stolen from a company or individual. Simple Ways to Stay Safe Online 1. Use strong passwords — at least 12 characters with numbers, letters, and symbols. 2. Don’t click suspicious links or download unknown attachments. 3. Keep software updated — updates fix security holes. 4. Enable multi-factor authentication (MFA) wherever possible. 5. Think before you share personal information on social media.
