1. What Is
Cybersecurity?
Cybersecurity refers to the practice of protecting computers, servers,
mobile devices, networks, and data from malicious attacks. It encompasses a
range of tools, processes, and practices designed to safeguard information
systems from unauthorized access, damage, or theft.
Cybersecurity is not just about installing antivirus software—it's about
understanding the risks and acting proactively. This includes protecting your
personal data, securing your devices, and staying informed about common online
threats.
2. Common Types of
Cyber Threats
You must know what you're up against in order to protect against
attacks. Here are some of the most common cyber threats:
·
Phishing: Deceptive emails
or messages that trick users into giving away sensitive information.
·
Malware: Malicious
software such as viruses, worms, or ransomware that can damage or control your
system.
·
Ransomware: A type of malware
that locks your data and demands payment to unlock it.
·
Man-in-the-Middle Attacks: When
attackers intercept communication between two parties to steal data.
·
Social Engineering:
Manipulating people into revealing confidential information.
Being aware of these threats is the first step toward prevention.

Cybersecurity Practices

4. Protecting
Personal and Business Data
Whether it’s personal photos or sensitive client information, protecting
data is critical. Always back up important data—preferably both in the cloud
and on a physical device. Encrypt sensitive files when possible and ensure
you’re complying with any relevant data protection laws (like GDPR or HIPAA if
you're in business).
For businesses, educating employees on cybersecurity best practices is just as important as
having strong technical defenses. The weakest link in the security chain is
frequently human error.
