Network Security involves taking software and hardware preventive measures to help protect an organization’s underlying network infrastructure from any unauthorized access, malfunction, improper disclosure, modification, misuse, or destruction, thus creating a much secure platform for hardware (computers), programs, and users, so that computers can perform their critical functions in a much more secure environment. However, small- and medium-sized enterprises may not have the IT resources of multinationals and other large organizations. Activities designed to protect a network enhance usability, safety, integrity, and reliability of networks and data. Network security aims at stopping various threats from infiltrating and spreading to the rest of the network.

Relentless cyber criminals, careless users, and disgruntled employees are all capable of bringing down your organization’s computer networks and substantially compromise data. Hardware and software, and policies and procedures are all aspects of network security designed to protect against external and internal threats to your organization’s computer systems. We can install multiple layers of both hardware and software to help prevent threats from destroying computer networks, or stop them from damaging and spreading to other parts of the system. Organizations with computer networks need network security to protect their hardware and software from external and internal threats. Common threats to a computer system include hacker attacks, data theft, identity theft, denial of service, and malicious programs such as Trojan horse, worms, viruses, botnets, malware, spyware, adware.

These threats seek to exploit unsecured websites, unsecured wireless networks, weak passwords, unpatched software, unpatched hardware, lost devices, users with malicious intent, unwitting users, and potentially unwanted applications. Network security fundamentals remain key to downtime prevention, reputation protection, reduced liability, and government regulation compliance.
