What is Network Security?

Are you interested in learning about network security? With more and more businesses becoming dependent on computer networks to operate efficiently, the need for security to keep information private has become greater. If you use a computer on any type of network where data needs to be kept private, learning what network security and why it is important can be very useful. Read this basic guide to security policies and activities so that you can gain an understanding on how the practice can benefit you and your business. 

What is a Network Security Strategy and Policy?

Network security is a strategy that is deployed by small, medium and large-sized businesses in an effort to keep the company's network, network traffic, assets, and data safe from hacker attacks and many other common Internet threats. While network security is a strategy that is designed by IT executives and management, it can also be an activity when IT security policies have been developed and when these policies are enforced. An effective network security policy will target threats that could potentially enter the network without authorization and stop them from gaining entry or harming data with viruses throughout the network. 

How Are Threats Detected?

To protect a network and defend that network against moderate and serious threats, network security programs and specialists must monitor the traffic within the network and analyze the traffic flows to look for abnormal activity. Whenever a user or application attempts to access any network, it will be identified by the firewall. Once identified, an intrusion prevention system or a specialist will have the power to full see all of the details on the user and inspect its activity in the network. During this time, a user may be identified as one of the many types of threats that exist. Some common types of threats that are detected trying to access private networks include Trojan horses, worms, spyware, adware, hacker attacks, zero-day attacks, data interception, data theft, and identity theft. 

What Is a Network Security Specialist and What Do They Do Daily? 

Network security is accomplished by using special software programs and hardware devices to identify threats and deter them. Software must be updated and managed on a regular basis by a real person. A network security specialist is in charge of using software programs to detect threats, prevent intrusions within a network, and resolve threats. Their primary purpose is to protect confidential data stored on a computer network and to maintain the data's integrity by implementing security policies to thwart cyber crimes and data breaches. 

Specialists are responsible for monitoring networks around-the-clock and must identify when a machine or data has been compromised. They will need to follow response procedures when a threat has been detected, analyze security risks, and keep all intrusion programs updated and managed at all times. 

Now that you understand how networks are secured and what specialists in the field do, you can see just how important this practice is. As more and more technically savvy individuals learn to target intelligent systems with what seems like impenetrable security tools, the need for new practices and highly trained professionals will continue to grow.
