What is the main difference between information security, cyber security, and network security?

Information security, cyber security, and network security are related but distinct concepts in the domain of safeguarding digital assets. Here is how they differ:

1. Information Security:

– Focus: Information security pertains to safeguarding all forms of sensitive data, such as company secrets, personal information, financial records, etc.

– Application: It includes measures like encryption, access control, data integrity checks, and policies/procedures to ensure data privacy and prevent unauthorized access or disclosure.

2. Cyber Security:

– Focus: Cyber security deals with protecting systems, networks, and programs from digital attacks or unauthorized access.

– Application: It involves implementing firewalls, antivirus software, intrusion detection systems, and other technologies to defend against cyber threats like malware, ransomware, phishing, etc.

3. Network Security:

– Focus: Network security concentrates on securing the interconnected systems and devices within a network to prevent unauthorized access and ensure data confidentiality and integrity.

– Application: This includes implementing technologies like VPNs, secure sockets layer (SSL), firewalls, and monitoring tools to safeguard the network infrastructure from threats like hacking, data interception, and denial-of-service attacks.

In summary, while information security mainly focuses on protecting data, cyber security emphasizes safeguarding digital systems, and network security deals with securing the connectivity and infrastructure between systems.
