What are the potential ethical implications of using AI-driven automated threat detection systems in cybersecurity, particularly in scenarios where false positives or negatives could have significant real-world consequences?
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.

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.
