There are many ways for a hacker to enter a network. Email is the most popular by getting you to think that it is a legitimate email and getting you to click on a link or attachment that contains malware which is called Phishing. The same can happen when browsing the internet and accidentally clicking on websites that are infected. Protecting the network from attacks is important but designing the network to mitigate risk and keeping infected devices isolated from the rest of the network by segmenting is also important.
Some other Network Security components that need to be looked at are Network Access Control (NAC), Endpoint protection, Next Generation Firewalls (NGFW), Intrusion Prevention System (IPS), Email Security, User Entity Behavior Analytics (UEBA), Sandboxing, URL Filtering, DNS security, and SSL decryption.
WHY YOU NEED ENTERPRISE NETWORK SECURITY
Cyber Attacks are becoming more and more prevalent and as time goes on, we need security technology to keep up with ever evolving sophisticated threats. There is no such thing as one device or technology that can secure the environment, various security applications need to be implemented that all communicate together to stop the breaches or contain them as soon as possible.
Companies are being hit hard by Ransomware, a form of Malware that encrypts data whether it be on a computer, server, or storage device then asks you to pay for it to be de-crypted. Paying for it does not necessarily mean you will get your data back, so it is best to secure your network to reduce this risk. We need to be looking at attacks that originate on the internal network as well as from the outside 24x7.
