The CIA Triad: Confidentiality, Integrity, and Availability

At the core of cyber security lies the CIA triad, which encompasses three fundamental principles: confidentiality, integrity, and availability. Confidentiality ensures that data is accessible only to authorized individuals, preventing unauthorized access and data breaches. Integrity safeguards the accuracy and reliability of information by preventing unauthorized modifications or alterations. Availability guarantees that authorized users have uninterrupted access to systems and data when needed.

Cyber Security Fundamentals

To grasp the foundations of cyber security, it is essential to familiarize oneself with key terminology, common threats, and best practices. Concepts such as firewalls, encryption, vulnerabilities, patches, two-factor authentication (2FA), antivirus software, penetration testing, virtual private networks (VPNs), and security incident response plans play crucial roles in maintaining robust security measures.

Common Cyber Security Threats

Being aware of the common cyber threats is essential in developing effective defense strategies. Malware, including viruses, worms, and ransomware, poses significant risks to digital systems. Phishing attempts, which deceive users into revealing sensitive information, continue to be a prevalent threat. Data breaches, denial-of-service attacks, and insider threats also loom as potential dangers that individuals and organizations should be prepared to counter.

Cyber Security Best Practices

Implementing best practices is vital in fortifying cyber defenses. Some key measures include using strong and unique passwords, enabling automatic software updates to patch vulnerabilities, establishing a robust data backup strategy to mitigate potential data loss, and implementing network segmentation to limit the impact of potential breaches.
