One among the many project domains given by S-LOGIX , network security is also one. The need for Network Security is gaining its own significance in these recent times. With a Network Security System, all the files, data & personal information are kept safe and protected from unauthorized access from people present on the network and people outside it. Therefore, it is widely used in offices, banks, and many other organizations. The provisions and policies of Network Security help the network administrator to monitor any kind of misuse, modification or unauthorized access of a computer network. Thus, a number of cyber attacks and other harmful activities are prevented. Cryptography poses a threat to organizations and individuals too. With encryption, an employee of a company can sell proprietary electronic information to a competitor without the need to photocopy and handle physical documents. Electronic information can be bought and sold on “black networks” such as Black-Net with complete secrecy and anonymity — a safe harbor for engaging in both corporate and government espionage. The keys that unlock a corporation’s files may be lost, corrupted, or held hostage for ransom, thus rendering valuable information in accessible. This domain is selected by S-LOGIX for project working in order to meet every other student who are eager to work in many different domains.
