There are 5 main types of network security that you can take advantage:1. Network Access Control (NAC) - The Network Access Control or NAC controls which people can access your network and which ones can’t. It allows you to identify different users and devices, and find out if unauthorised personnel are trying to gain access to the network. You can therefore, enforce different security policies in order to block devices and control what can happen in your network.2. Application Security - You can also take advantage of application security, which is designed to offer complete protection to your applications. It is important, since it ensures that apps with flaws in them aren’t targeted and taken advantage of by hackers. It basically secures your network from the threat of your applications getting hacked, which is why it is definitely an essential network security tool you must have.3. Antivirus And Anti-malware Software - You must definitely use antivirus and anti-malware software in order to protect your network from spyware, phishing, Trojans, and viruses. Malware is like a disease for your network, and will not only stay within your network, but will spring attacks, and cause your systems to malfunction.4. Email Security - It is important that you give importance to email security as well, especially if you have a business that is primarily dealing with a lot of emails. Phishing attacks can severely compromise your business operations, which is why it is imperative that you invest in state-of-the-art email security.5. Wireless Security - Another network security type that you should invest in is wireless security. Businesses are conducting more business on the cloud, and this means wireless networks and access points. The big problem here is that wireless networks aren’t very secure, and can be easily attacked by hackers, which is your wireless security needs to be top notch.
