It goes without saying that network security is important. An unsecured network is not only dangerous for your enterprise, but it can also have effects on business productivity and satisfaction. If a security threat enters your network, it needs to be addressed – but that can take valuable time away from your IT department. If you don’t know where to begin devising a smart network security strategy, you need to learn the essentials ASAP.
The landscape of security threats is growing every day as more and more malware and threat actors are developed. Cybersecurity solutions need to evolve right alongside them to combat new hazards, especially for business network applications. What are the essentials of network security? Below, we’ve compiled the fundamental network security practices your enterprise needs to adopt.
Network security from multiple angles
Traditional and legacy network security solutions focused exclusively on deflecting incoming attacks from entering the network. Essentially, they would only defend the perimeter of your network, not the internal portion of the infrastructure. While this is still a necessary security measure today, it cannot be the only one in place. Perimeter network security doesn’t address issues that have already entered your network or that slip in undetected.
Your enterprise should be constantly monitoring its network for security threats that are hiding on your network. Through tools like network performance monitors (NPMs) and network detection and response (NDR), you can discover threats that have already breached your perimeter defenses. That way, you can create a network security plan that covers all the bases.
Internal security threats
Sometimes, the biggest threat to your enterprise network is your enterprise itself. Employees using your network can introduce security threats if they don’t utilize it safely. If an employee on your network accesses an unprotected or malware-infested website, that could introduce a host of issues to your network and spread everywhere. In addition to the right network security tools, your company should also educate its workers on basic network security practices. This could include keeping company network usage for business tasks only to awareness on what malicious attacks (like phishing scams) typically look like.
Network security and performance monitoring
Security threats often seek to slow down a network or cause a part of it to malfunction. When this is happening, it’s likely that your network’s performance is suffering as a result. If you have network monitoring solutions in your infrastructure, you can catch these performance-affecting security issues as they happen.
For example, denial-of-service (DoS) attacks deliberately request large amounts of data from your network in order to overload it. An NPM constantly observes your network for performance issues, including spikes in traffic and data requests. The tool then alerts your enterprise to the situation and, depending on the tool, can help you identify the source of the problem.
