It has been one of the critical requirements in network planning and design. It involves design requirements on topology, protocol, bandwidth allocation, etc.. Topology requirement can be maintaining a minimum two-connected network against any failure of a single link or node.
Network security are security controls, policies, processes and practices adopted to prevent, detect and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. [1] Network security involves the authorization of access to data in a network, which is controlled by the network ...
The security associations of IPsec are established using the Internet Security Association and Key Management Protocol (ISAKMP). ISAKMP is implemented by manual configuration with pre-shared secrets, Internet Key Exchange (IKE and IKEv2), Kerberized Internet Negotiation of Keys (KINK), and the use of IPSECKEY DNS records .
A fully connected network, complete topology, or full mesh topology is a network topology in which there is a direct link between all pairs of nodes. In a fully connected network with n nodes, there are () direct links. Networks designed with this topology are usually very expensive to set up, but provide a high degree of reliability due to the ...
A HAIPE is an IP encryption device, looking up the destination IP address of a packet in its internal Security Association Database (SAD) and picking the encrypted tunnel based on the appropriate entry. For new communications, HAIPEs use the internal Security Policy Database (SPD) to set up new tunnels with the appropriate algorithms and settings.
The RON nodes monitor the Internet paths among themselves and will determine whether or not to reroute packets directly over the Internet or over other RON nodes thus optimizing application-specific metrics. [3] The Resilient Overlay Network has a relatively simple conceptual design. RON nodes are deployed at various locations on the Internet.
There are a number of specific classifications but all lie on a continuum between the dumb network (e.g. the Internet) and the intelligent network (e.g. the PSTN). A popular example of such usage of the term in distributed applications, as well as permanent virtual circuits, is the organization of nodes in peer-to-peer (P2P) services and networks.
Internet security is a branch of computer security. It encompasses the Internet, browser security, web site security, [1] and network security as it applies to other applications or operating systems as a whole. Its objective is to establish rules and measures to use against attacks over the Internet. [2]
