In today’s world, where everything is online, cybersecurity has become a must. It’s all about keeping our digital information and systems safe from hackers and other threats. Whether you’re protecting personal details or big company data, cybersecurity plays a key role in making sure everything stays secure. Let’s break down what cybersecurity is and how you can become an expert in this important field.
What is Cybersecurity?
Cybersecurity is the practice of protecting computers, networks, and data from theft, damage, or unauthorized access. Think of it like a digital lock on your computer and online accounts, ensuring that only the right people can get in.
Main Goals of Cybersecurity:
- Confidentiality: Keeping information secret and accessible only to those who have permission.
- Integrity: Making sure that information isn’t changed or tampered with by anyone who shouldn’t be touching it.
- Availability: Ensuring that systems and data are up and running for users who need them.
Common Cyber Threats
- Malware: Malicious software like viruses and ransomware designed to harm your computer or steal data.
- Phishing: Fake emails or messages that trick you into giving away personal information.
- Man-in-the-Middle Attacks: When someone secretly intercepts and possibly alters the communication between two parties.
- Denial-of-Service Attacks: Overloading a system or network so that it stops working properly for users.
