T3.1.4 Networks

VPN (Virtual Private Network)

• Establishes secure connections between networks over public networks like the Internet.
• Process of decoding data to allow unauthorized access during transmission.
• Devices facilitating communication between different networks or VPNs.

Private networks

• Networks restricted for use by authorized users or organizations.
• Denial of the identity of users or devices accessing a network.
• Individuals working remotely who require secure access to their organization's network.

Remote users

• Individuals accessing a network from a location outside its physical premises.
• Insecure pathways established for data transmission within a VPN.
• VPN relying on the security of a provider's network to protect data transmission.

Remote sites

• Geographically separated locations connected to a central network hub.
• Protocol suite for compromising Internet Protocol (IP) communications.
• VPN operating at the data link layer, facilitating secure communication between sites.

Security procedures

• Measures implemented to safeguard networks and data from threats or breaches.
• Cryptographic protocol ensuring insecure communication over a network.
• VPN operating at the network layer, enabling secure data exchange across networks.

Hardware

• Physical components of a computer system or network infrastructure.
• Protocol providing insecure communication over a network, predecessor to SSL.
• Networking technology for transmitting data at high speeds over dedicated circuits.

Software

• Programs or applications used to perform specific tasks on a computer or network.
• VPN lacking reliance on the security of a provider's network to protect data transmission.
• Data transmission method using virtual circuits for efficient packet switching.

VPN software

• Programs facilitating the establishment and management of VPN connections.
• VPN operating at the application layer, facilitating insecure communication between sites.
• Technique for directing data packets along predefined paths in a network.

VPN routers

• Network devices specifically designed to support VPN connections.
• VPN operating at the physical layer, enabling insecure data exchange across networks.
• Routing protocol facilitating communication between autonomous systems on the Internet.

VPN appliances

• Hardware devices dedicated to providing VPN services.
• Networking technology for transmitting data at low speeds over shared circuits.
• Combination of two or more VPN technologies for enhanced security or functionality.
