Network Security

Network security systems protect networks and their services from unauthorized modification, destruction, or disclosure, and assures that the network performs its critical functions correctly. Network security is essential for business that rely on computer systems. Proper safeguarding of everything associated with a network, including data, media, and equipment is vital for companies to function effectively in globally integrated business environments. Companies that provide network security provide administrative functions, such as threat assessment, technical tools and facilities, such as cryptographic products, and network access control products, such as firewalls. They will also make certain that network resources are used in accordance with a prescribed policy and only by people who are authorized to use these resources. Network security also includes providing for data integrity.
