Network security is, in its simplest terms, a set of guidelines designed to protect the integrity and accessibility of computer networks, and the data in use by your organization. This is done by using both software and hardware, designed for the very purpose of network security. Every organization, regardless of size, requires some degree of network security in place to protect it from cyber attacks. The growing example of cyber threats happening daily are only further evidence of the fact that you must have some way to deal with these issues.
The network architecture in today’s technical society can be difficult to understand at times, and it is faced with a constantly, potentially threatening environment that is always subject to change. Cyber attackers are always trying to find and exploit vulnerabilities in this infrastructure, and these vulnerabilities can exist in a broad number of areas. 
Devices, applications, and users are all affected by cyber attacks, because of this, because there are so many affected areas, there are many network security management tools and applications organizations people use today to keep their network secure and private from these prying eyes. Although it is also important to keep your network safe from individual threats, that may be internal or external in origin. Ensuring that your data and all network security aspects put in place by you or your organization follow the correct compliance requirements will also ward off non-compliance in not only the organization, but in all of the components being used by you. When each moment is crucial in the running of your softwares and hardwares, mere moments of downtime can cause disruption and damage to the organization’s most crucial part, its bottom line, on a massive scale; it is essential that these protection measures are in place.
