Which of the following is a technique used for modifying messages, providing Information and Cyber security, and reducing the risk of hacking attacks during communications and message passing over the Internet?
C. Cryptography.
Cryptography involves securing communication by encrypting messages to prevent unauthorized access or tampering. It uses mathematical algorithms to transform plaintext into ciphertext, making it unreadable without the cryptographic key. This ensures confidentiality and integrity of data being transmitted over networks or stored in storage systems.
Cryptographic techniques also enable secure authentication by verifying the identity of parties involved in a communication using digital signatures or certificates. Additionally, cryptography provides non-repudiation services so that senders cannot deny having sent a particular message.
While tools such as risk analysis (A), OODA loop (B), and firewall security (D) play important roles in information and cybersecurity, they do not provide encryption capabilities for modifying messages like cryptography does.
