The purpose of the TLS (Transport Layer Security) record layer is to ensure secure communication between client and server over a network by providing confidentiality, integrity, and authentication of data transmitted. It achieves this through encryption, message authentication codes (MACs), and cryptographic algorithms. The record layer encapsulates higher-level protocol data into records, which are then … Read more
SSH (Secure Shell) and SSL (Secure Sockets Layer) are cryptographic protocols used to secure communications over networks, but they serve different purposes and operate at different layers of the networking stack. SSH is primarily used for securely accessing and managing remote computers or servers over an insecure network. It provides encrypted communication channels, authentication mechanisms, … Read more
The purpose of the SNMP (Simple Network Management Protocol) service is to enable centralized monitoring and management of network devices and systems. SNMP allows network administrators to gather information, configure settings, and monitor the performance of network devices such as routers, switches, servers, and printers. By providing a standardized method for communication between network devices … Read more
The purpose of an internet gateway is to provide a connection between a private network, such as a local area network (LAN), and the internet. It serves as an entry and exit point for network traffic between internal network devices and external internet resources. Internet gateways typically include routing and network address translation (NAT) functionalities … Read more
SFTP, or Secure File Transfer Protocol, uses a client-server architecture to transfer files securely over a network. The client initiates a connection to the server using port 22 by default. Authentication typically involves a username and password or public key authentication. Once authenticated, the client can request files from the server by specifying the filename … Read more
Network security involves implementing various measures to protect the integrity, confidentiality, and availability of data and resources within a network. It encompasses technologies, policies, and practices designed to defend against unauthorized access, misuse, modification, or denial of network-accessible resources. Key components include firewalls, intrusion detection systems (IDS), encryption protocols, and access control mechanisms. These defenses … Read more
CCM in cloud security stands for Cloud Controls Matrix. It is a framework developed by the Cloud Security Alliance (CSA) to help organizations assess the security posture of cloud service providers. The CCM provides a set of security controls and best practices that address various aspects of cloud computing, such as data security, identity management, … Read more
A peer-to-peer network is a decentralized network architecture where individual nodes (computers or devices) communicate directly with each other without relying on a central server. Each node in the network can act as both a client and a server, sharing resources such as files, computing power, or services with other nodes in the network. This … Read more
The WAN (Wide Area Network) connection method refers to how devices and networks connect and communicate over large geographical distances. It involves using various technologies and protocols to establish reliable and secure communication links between different locations. WAN connection methods include leased lines, such as T1/E1 lines, which provide dedicated point-to-point connections with guaranteed bandwidth. … Read more
Cloud storage refers to a service model where data is stored, managed, and maintained remotely on servers accessible over the internet. It allows users to store and retrieve data from anywhere with an internet connection, eliminating the need for physical storage devices like hard drives or flash drives. Cloud storage providers typically offer scalable storage … Read more
