The cyber security framework plays a major role in tackling cyber threats via the National Cyber Security Policy (2013) which has made progress against digital threats since it’s inception .
Evaluation of cyber security framework:
Strengths :
1)Legal and regulatory framework: The Information Technology act (2000) and National Cyber Security Policy (2013) aim to detect cyber threats towards data protection and online transactions. The legal framework criminalizes cyber offences and develop country’s protection against threats.
2) Setting up institutions such as :
- Indian Computer Emergency Response Team(CERT-In) which is responsible for threat response and management.
- National Critical Information Infrastructure Protection Centre (NCIIPC) which provides physical protection against threats such as Social engineering or natural disasters.
- National Cyber Coordination Centre (NCCC) which provides communication between various agencies .
3) National Cyber Security Policy:Marks strategic objectives effective cyber ecosystem via promotion of research and development .
4) Focus on capacity building.
5) Provide indigenous solution: NCRF promotes participation of companies like TCS ,Wipro, Cyber ark etc for cyber defence.
6) Public-private partnership
Reforms to further strengthen defences:
1) Awareness campaigns: best possible way of defending threats is informed masses.
2) Continuous review and adaptation: dynamic scenario which requires regular evaluation and modification.
3) Increased budget allocation: both by government and private parties monitored by top management ( 10% of IT budget recommended).
4) Training programmes as recently announced by HM Amit Shah of training 5000 commandos .
5) Acts such as Digital India which would encompass A.I , cybersecurity and data privacy.

Compare ipv4 and ipv6 in detail
-
The primary differences between IPv4 and IPv6 are. :- 1. Address Length : - *IPv4*: Uses a 32-bit address space, which allows for approximately 4.3 billion unique addresses. - *IPv6*: Uses a 128-bit address space, providing an exponentially larger number of addresses (about 340 undecillion). 2.

The primary differences between IPv4 and IPv6 are. :-
1. Address Length :
– *IPv4*: Uses a 32-bit address space, which allows for approximately 4.3 billion unique addresses.
– *IPv6*: Uses a 128-bit address space, providing an exponentially larger number of addresses (about 340 undecillion).2. Address Notation :
– *IPv4*: Addresses are written in decimal format as four octets separated by dots (e.g., 192.168.1.1).
– *IPv6*: Addresses are written in hexadecimal format as eight groups of four hexadecimal digits separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).3. Header Complexity :
– IPv4 : Has a more complex header with various fields, which can lead to higher processing overhead.
– IPv6 : Has a simplified header structure to improve processing efficiency and performance.4. Configuration :
– IPv4: Can be manually configured or obtained via DHCP (Dynamic Host Configuration Protocol).
– IPv6 : Supports auto-configuration and Stateless Address Autoconfiguration (SLAAC), reducing the need for manual configuration or DHCP.5. *NAT (Network Address Translation)*:
– IPv4 : Often uses NAT to deal with address shortages by allowing multiple devices to share a single IP address.
-IPv6 : Designed to eliminate the need for NAT due to its vast address space, allowing every device to have a unique IP address.6. Security :
– IPv4*: Security features like IPsec (Internet Protocol Security) are optional.
– IPv6 : IPsec is a mandatory feature, providing built-in support for encryption and authentication.7. Broadcasting :- IPv4 Supports broadcast communication (sending data to all devices on a network).
IPv6 : Does not support broadcasting; instead, it uses multicast and anycast to achieve similar outcomes.These differences make IPv6 better suited for the expanding needs of the modern internet, providing greater address space, improved efficiency, and enhanced security.

Difference between symmetric and assymetric encryption
-
Symmetric encryption uses the same key for both encryption and decryption. This means that the sender and receiver must both have the same secret key, making it fast and efficient but requiring secure key exchange. Asymmetric encryption, on the other hand, uses a pair of keys: a public key for encryRead more
Symmetric encryption uses the same key for both encryption and decryption. This means that the sender and receiver must both have the same secret key, making it fast and efficient but requiring secure key exchange. Asymmetric encryption, on the other hand, uses a pair of keys: a public key for encryption and a private key for decryption. This allows for secure communication without needing to share the private key, but it’s generally slower and more complex than symmetric encryption.
