This beginner's guide will provide you with a solid foundation to navigate the complex landscape of cyber security.

Understanding Cyber security 

Cyber security is the practice of safeguarding digital systems, networks, and data from unauthorized access, attacks, and damage. It encompasses a wide range of techniques and technologies designed to protect the confidentiality, integrity, and availability of information.

Key Concepts

1. Threats and Attack Vectors

Malware: Malicious software includes viruses, worms, Trojans, and ransomware. They can infiltrate your system and cause harm.

Phishing:

 Cyber criminals use deceptive emails or messages to trick you into revealing sensitive information like passwords or financial data.

Social Engineering: Attackers manipulate people into divulging confidential information or performing actions that compromise security.

Denial of Service (DoS) Attacks: These aim to overload a system, making it unavailable to legitimate users.

2. Security Layers

Network Security: Protects the integrity and confidentiality of data as it travels across networks. Firewalls, VPNs, and intrusion detection systems are common tools.

Endpoint Security: Focuses on securing individual devices like computers and smartphones. This includes antivirus software and device encryption.

Data Security: Involves encryption, access controls, and data backup to ensure the confidentiality and availability of data.

 3. Passwords and Authentication

- Use strong, unique passwords for each account.

- Enable two-factor authentication (2FA) wherever possible.

- Avoid sharing passwords and be cautious about password recovery questions.

4. Software Updates
