Cyber security is no longer a niche field, it’s a critical component of our interconnected world. From protecting personal data to safeguarding national infrastructure, the need for skilled cyber security professionals has never been greater. Understanding the breadth of this landscape is the first step in your self-guided learning journey.

1.1. What Does Cyber Security Encompass?

Cyber security, also known as information technology security, encompasses a wide array of disciplines aimed at protecting computer systems, networks, and data from cyber threats. These threats can range from individual hackers to organized crime syndicates and even state-sponsored actors. According to a report by Cybersecurity Ventures, cybercrime is projected to cost the world $10.5 trillion annually by 2025, highlighting the importance of robust cyber security measures. Cyber security is a broad field that includes:

Network Security: Protecting computer networks from unauthorized access and misuse.
Endpoint Security: Securing devices such as laptops, desktops, and mobile phones that connect to a network.
Data Security: Implementing measures to protect data both in transit and at rest.
Application Security: Ensuring the security of software applications.
Cloud Security: Protecting data and infrastructure in cloud environments.
Incident Response: Handling and recovering from cyber security incidents.
Vulnerability Management: Identifying and mitigating vulnerabilities in systems and software.
Compliance: Adhering to relevant laws, regulations, and standards such as GDPR, HIPAA, and PCI DSS.

1.2. Key Cyber Security Concepts

Before diving into specific skills and resources, it’s important to grasp some fundamental cyber security concepts. These concepts will form the foundation of your knowledge and guide your learning as you progress.

Concept	Description	Importance
Confidentiality	Ensuring that sensitive information is accessible only to authorized individuals or systems.	Prevents unauthorized disclosure of data, protecting privacy and intellectual property.
Integrity	Maintaining the accuracy and completeness of data.	Ensures that data is not altered or corrupted without authorization, maintaining trust in information.
Availability	Ensuring that systems and data are accessible to authorized users when needed.	Guarantees that services and data are available for legitimate purposes, preventing disruptions to business operations.
Authentication	Verifying the identity of users, devices, or systems.	Ensures that only authorized entities gain access to resources, preventing unauthorized access.
Authorization	Defining the level of access that authenticated users have to resources.	Limits the actions that users can perform, preventing them from accessing or modifying resources beyond their authorized scope.
Non-Repudiation	Ensuring that actions performed by users can be traced back to them, preventing them from denying their actions.	Provides accountability and helps in investigating security incidents.
Risk Management	Identifying, assessing, and mitigating cyber security risks.	Helps organizations prioritize security efforts and allocate resources effectively to protect against the most critical threats.
Defense in Depth	Implementing multiple layers of security controls to protect against a variety of threats.	Ensures that if one security control fails, others are in place to provide additional protection.
Least Privilege	Granting users only the minimum level of access necessary to perform their job functions.	Reduces the potential damage that can be caused by insider threats or compromised accounts.
Zero Trust Security	Assuming that no user or device is inherently trusted and requiring verification for every access request.	Minimizes the risk of unauthorized access by continuously verifying the identity and security posture of users and devices.
Encryption	Converting data into a coded format to prevent unauthorized access.	Protects data in transit and at rest, ensuring that it remains confidential even if intercepted by unauthorized parties.
Firewalls	Network security systems that monitor and control incoming and outgoing network traffic based on predefined security rules.	Prevent unauthorized access to networks and systems, protecting against external threats.
