Screening routers
Screening routers: Network devices that filter packets to control access and manage traffic between different parts of a network. They are configured with specific rules to block or allow traffic based on factors such as source and destination IP addresses, ports, or protocols. The goal of a screening router is to enhance network security by […]
Secure communications
Secure communications: The use of cryptographic techniques to protect the confidentiality, integrity, and authenticity of communication between two or more parties. It is used to prevent unauthorized access to sensitive information and to protect against man-in-the-middle attacks. Examples include using encryption to protect the contents of an email, using digital signatures to verify the authenticity […]
Secure FTP (SFTP)
Secure FTP (SFTP): A secure protocol for transferring files over a network, ensuring the confidentiality and integrity of the transferred files and preventing unauthorized access to sensitive information. Examples include transferring sensitive documents between two parties, financial data between a client and a server, and software updates to a network of devices.
Secure Hypertext Transfer Protocol (S-HTTP)
Secure Hypertext Transfer Protocol (S-HTTP): S-HTTP was an extension of HTTP to support the secure exchange of data over the internet. However, it has not been widely adopted, and its use has been largely superseded by HTTPS, which combines HTTP with the SSL/TLS protocol to provide a secure browsing experience.
Secure Shell (SSH)
Secure Shell (SSH): A network protocol that enables secure remote login and other secure network services over an unsecured network. SSH provides robust authentication and secure encrypted data communication between two computers connecting over an open network, ensuring the confidentiality and integrity of data transmitted. It is widely used by network administrators for remotely controlling […]
Secure Socket Layer (SSL)
Secure Socket Layer (SSL): A cryptographic protocol designed to provide secure communications over a computer network. SSL uses a combination of public key and symmetric key encryption to secure a connection between two machines, typically a web server and a client, over the internet. It was widely used for securing data transfer, ensuring the privacy […]
