What are the different elements of cyber security? Keeping in view the challenges in cyber security, examine the extent to which India has successfully developed a comprehensive National Cyber Security Strategy.

Cyber Security is protecting cyber space including critical information infrastructure from attack, damage, misuse and economic espionage.

Elemets of Cyber security Architecture:

1. Network Elements: Network nodes like computers, NICs, repeaters, hubs, bridges, switches, routers, modems, gateways. 
2. Security Elements: like firewalls, Intrusion Detection/Protection Systems [IDS/IPS], encryption/decryption devices. 
3. Security Frameworks & Standards: Cybersecurity framework architecture standards like NIST Risk Management Framework.

Vulnerabilities to the Architecture:

1. Data Diddling: Attack floods systems, servers, or networks with traffic to exhaust resources and bandwidth. 
2. Ransomware: Blocks access to key components of the network and demand money to unlock it. 
3. Phishing: The goal is to steal sensitive data like credit card and login information or to install malware on the victim’s machine 
4. Malware: Covertly obtains information by transmitting data from the hard drive (spyware) 

National cyber security strategy to ensure a safe, secure, trusted, resilient, and vibrant cyberspace for India.

1. Security by Design:- To develop institutional capability for assessment, evaluation, certification and rating of core devices. 
2. Monitoring of Supply chain of integrated circuits. 
3. Product testing and certification needs to be enhanced. 
4. The supervisory control and data acquisition (SCADA) security should be integrated with enterprise security. 
5. A minimum allocation of 0.25% of the annual budget is required for cyber security. 
6. Holding cyber security drills to tackle crisis management. 
7. Create cyber security services under Indian enginerring services. 
8. Cyber insurance to address risk. 
9. Cyber diplomacy. 
10. Setting up exclusive court to deal with cyber investigation.
