A Quick Overview Of Network Security And Its Importance

Undoubtedly, data is the most valuable asset of every business. “Many leading business organizations invest millions of dollars each year to secure their computer networks and to keep their trade data safe,” says an expert from ACIT Institute. No company can afford to lose the important research data on which the company has invested millions of dollars and has been working for years!

Network Security, a fundamental branch of computer science, pertains to securing a computer network and network infrastructure devices to avoid illegal access, network exploitation, data theft and device modification. In addition, Network Security also involves preventing Denial of Service (DoS) attacks and assuring persistent service for genuine network users. Network Security endows the network users with hands-on defense methods and mechanisms to protect data and network from external and internal threats.
