A potential solution for solving forensic is the use of blockchain in software defined networking (sdn).
Network security is devoted to solving your network security issues in detail, now with even more news, information and solutions to your network security problems. Every month network security covers authoritative news and analysis of significant events, including major trends in threats, attacks and regulatory changes.
After analyzing and quantifying the network information security elements confidentiality, integrity and availability, this paper defines the network security confidentiality vector, the network security integrity vector and the network security availability vector, and also builds the hierarchical indicator system of network security evaluation.
Abstract network security & cryptography is a concept to protect network and data transmission over wireless network. Data security is the main aspect of secure data transmission over unreliable network. Network security involves the authorization of access to data in a network, which is controlled by the network administrator.
Use, use of security monitoring functions, and current and planned reliance on third-party services for network security.
