Cybersecurity refers to the techniques and practices used to protect computer systems, networks, and data from digital attacks, unauthorized access, damage, or theft. As our world becomes more digital, cybersecurity is essential for individuals, businesses, and governments.
Personal data such as your name, passwords, photos, and banking information is stored online.
Businesses hold sensitive customer records, financial information, and trade secrets.
A breach can lead to identity theft, financial loss, and reputation damage.
Core Principles of Cybersecurity (CIA Triad):
Confidentiality – Only authorized individuals should have access to data.
Integrity – Data should remain accurate and unaltered unless updated by authorized users.
Availability – Systems and data should be accessible to users when needed.
Key Areas of Cybersecurity:
Network Security: Protects the integrity and usability of networks and data.
Application Security: Ensures software is secure from vulnerabilities and bugs.
Cloud Security: Safeguards data stored in cloud-based services.
Endpoint Security: Protects devices like laptops and phones from threats.
Information Security: Protects sensitive data, both in digital and physical formats.
Real-Life Application:
Imagine a hospital's network gets hacked. Without cybersecurity:
Patient records could be stolen.
Medical devices could be shut down.
Lives could be at risk.
