  • Security Protocols

    ,

    Explanation:Security protocols are sets of rules and procedures designed to protect data transmission and communication over networks. They define methods for secure key exchange, encryption, data integrity, and authentication. Examples include SSL/TLS, IPsec, and HTTPS. These protocols are essential for protecting sensitive information and ensuring privacy in online interactions, such as financial transactions and data…

  • Man-in-the-Middle (MITM)

    ,

    A Man-in-the-Middle (MITM) attack is a form of cyberattack where an attacker secretly intercepts and manipulates communication between two parties without their knowledge. In a typical MITM scenario, the attacker positions themselves between a user and a legitimate service. They can eavesdrop on sensitive data exchanges or inject malicious content into the communication. MITM attacks…

  • SSL/TLS (Secure Sockets Layer/Transport Layer Security)

    ,

    Explanation:SSL (Secure Sockets Layer) and TLS (Transport Layer Security) are cryptographic protocols used to establish secure communication over networks, particularly the internet. TLS is an improved version of SSL and is widely adopted today. These protocols ensure data confidentiality, integrity, and authenticity by encrypting the communication between a client and a server. SSL/TLS is the…

  • Public Key Infrastructure (PKI)

    ,

    Explanation:Public Key Infrastructure (PKI) is a framework that enables secure communication over networks by managing the creation, distribution, and verification of digital certificates and public keys. It forms the foundation for many secure internet protocols, such as HTTPS and digital signatures. PKI involves components such as Certificate Authorities (CAs), Registration Authorities (RAs), digital certificates, and…

  • Bus Topology

    ,

    Bus topology is a network setup where all devices share a single central communication cable (bus). Elaboration: Example: Older Ethernet networks used a coaxial bus topology, where all computers connected to a single cable.

  • Mesh Topology

    ,

    Mesh topology is a network design where each device connects to multiple other devices, ensuring high reliability. Elaboration: Example: A wireless mesh network (WMN) in smart cities, where multiple Wi-Fi routers interconnect for seamless coverage.

  • Hub-and-Spoke Topology

    ,

    Hub-and-Spoke topology is a network design where multiple devices (spokes) connect to a central hub, which manages communication. Elaboration: Example: A corporate VPN where branch offices (spokes) connect to a central headquarters (hub).

  • TCP/IP Stack

    ,

    The TCP/IP model is a four-layer networking model used for internet communication, consisting of Application, Transport, Internet, and Network Interface layers. Elaboration: Example: When you send an email, the TCP/IP stack ensures the message is transmitted and received correctly over the internet.

  • IPv6

    ,

    IPv6 (Internet Protocol version 6) is a 128-bit addressing system designed to replace IPv4 and support a vast number of unique addresses. Elaboration: Example: A typical IPv6 address looks like this: 2001:0db8:85a3::8a2e:0370:7334 Most modern devices and ISPs now support IPv6.

  • IPv4

    ,

    IPv4 (Internet Protocol version 4) is a 32-bit addressing system used to uniquely identify devices on a network. Elaboration: Example: A typical IPv4 address looks like this: 192.168.1.1 This is often used for local networks and router configurations.
