Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. It's also known as information technology security or electronic information security.

Explanation: Application security, operational security, network security all are the main and unforgettable elements of Cyber Security.

Cybersecurity is critical because it helps to protect organizations and individuals from cyber attacks. Cybersecurity can help to prevent data breaches, identity theft, and other types of cybercrime.

Ten types of cybersecurity

• Application security. Application security prevents unauthorized access and use of applications and connected data.
• Cloud security.
• Critical infrastructure security.
• Data security.
• Endpoint security.
• IoT (Internet of Things) security.
• Mobile security.
• Network security.

When we discuss data and information, we must consider the CIA triad. The CIA triad refers to an information security model made up of the three main components: confidentiality, integrity and availability. Each component represents a fundamental objective of information security.

Cyber security is important because it safeguards individuals and organizations against cyber attacks and theft or loss of sensitive and confidential information.

Top Cybersecurity Companies to Know

• Palo Alto Networks.
• McAfee.
• CrowdStrike.
• Deepwatch.
• Rapid7.
• KnowBe4.
• Ping Identity.
• Duo Security.

The purpose of the cyber security principles is to provide strategic guidance on how an organisation can protect their systems and data from cyber threats. These cyber security principles are grouped into four key activities: govern, protect, detect and respond.

To summarise, the primary goal of cybersecurity is to ensure the privacy of information, the correctness of data, and access to authorized users. This brings us to focus on the 3 crucial aspects of security which are confidentiality, integrity, and availability of data collectively known as the CIA Triad.
