Effective network security targets a variety of threats and stops them from entering or spreading through the network. Network security has been accomplished through the use of hardware and software. Such programs prevent malicious applications to interfere in the network and prevent leakage of information. Network security also deals with the prevention of the network being affected by spyware and the use of firewalls. We at Chennai Projects provide our clients with all the projects based on network security. Topics such as encryption, cryptography, firewall, pen-testing etc, are done by us.
