# What is Cyber security and Information security

## Definition
Information security: Protecting information, regardless of its format, from unauthorized access, use, disclosure, disruption, modification, or destruction.
Broader: Covers all forms of information, including physical and digital.
Cybersecurity: Protecting systems, networks, and data from cyber threats, focusing on technology and digital environments.
Narrower: Focuses specifically on protecting digital systems, networks, and data.

## Principles of Cybersecurity
In cybersecurity, the CIA Triad is a foundational model representing the three core principles of information security. These principles ensure the effective protection of data and systems.
- **Confidentiality**: Ensures that information is accessible only to those authorized to access it.
- **Integrity**: Ensures that data is accurate, complete, and unaltered during storage or transmission.
- **Availability**: Ensures that information and resources are accessible to authorized users when needed.

## Different types of cyber threats
- **Social Engineering**
Social engineering is a manipulation technique that exploits human nature to gain private information, access, or valuables. In cybercrime, these “human hacking” scams tend to lure unsuspecting users into exposing data, spreading malware infections, or giving access to restricted systems. Attacks can happen online, in-person, and via other interactions.

- **Malware**
Harmful software that can access a system's data, such as viruses, spyware, ransomware, and worms.

- **Phishing**
