Tunneling, in the context of computer networks, refers to the process of encapsulating one network protocol inside another to securely transmit data across an untrusted network. This allows for secure communication over networks that may not inherently support the desired protocol or offer sufficient security measures. Key Characteristics / Core Concepts Encapsulation: Data packets are … Read more
Network security is the protection of computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves a range of technologies and processes designed to ensure the confidentiality, integrity, and availability of network resources. Network security is crucial for protecting sensitive data, maintaining operational continuity, and safeguarding against cyber threats. Key Characteristics / … Read more
Cryptography is the practice and study of techniques for secure communication in the presence of adversarial behavior. It involves transforming readable data (plaintext) into an unreadable format (ciphertext) and back again. Key Characteristics / Core Concepts Confidentiality: Ensuring only authorized parties can access information. Integrity: Guaranteeing data hasn’t been tampered with. Authentication: Verifying the identity … Read more
