Network infrastructure can be a good investment if you know how to take care of it. Keeping it secure may not be an easy task, but its’ well worth it in the end. Outlined below are nine important ways you can make sure that your network remains an asset rather than a liability.
1. Understand your network design.
Unless you know how the infrastructure works, you’re in a dead zone. Knowing how data flows from system to system and how devices receive and transmit signals are key points to protecting your network. If you don’t have a good grasp of these concepts, you can’t successfully secure your network just yet. This is the first crucial step in the process.
2. Review your applications.
Your network can be infected through the different applications that run in your system. That is why it is important to review your digital applications and monitor them constantly to guarantee that they are safe and secure. Scan your devices for viruses and malware so as not to make your entire infrastructure vulnerable to malicious attacks. Implement a virus protection that prevents worms, viruses, and trojans from entering your system via the web.
3. Find holes in your network.
Every network has at least one weak link, and your job is to find yours early to prevent critical data from leaking. You don’t want your company’s intellectual properties to be accessed by people who are not supposed to get a hold of them. It’s wise to document all your network connections and make sure that things are where they’re supposed to be. Review your security policies and protect every device.
4. Build a firewall.
Raising a firewall is possibly the most important measure you should take when securing your network. A firewall serves as a border control that defines your perimeter. It prevents the unauthorized access to your private network, even if the access attempt comes from the inside. Learn how a firewall works and understand the extent of its coverage. Although a firewall can’t protect your network 100%, it can surely reduce the risk of security breach in your system.
As much as possible, keep your network infrastructure simple.Unless a service or device is a staple in your business, it’s probably just making your network infrastructure weaker.
5. Control circumventors.
No security policy is perfect. Even firewalls can be thwarted by what is known as circumventors. These circumventors may come in different forms. They go around security policies and give unauthorized users access to networks that they’re not supposed to rack up. Even when there are filters in the networks security control, circumventors can still allow unwanted traffic to visit a certain site. You can’t really stop these sophisticated entities, but you can control how they impact your network. Constantly monitor and track your traffic so you can intercept when a circumventor is meddling in your system. You may not be able to prevent the attack, but you may do something about its aftermath.
6. Use Secure Socket Layer.
An SSL or Secure Socket Layer is a protocol that establishes security between a web browser (server) and a website (client). It is like a tunnel that ensures that information travels from one to the other without the risk of it being intercepted by outside parties. SSL ensures that confidential information remains private when transmitted. For safety measures, encrypt your connections with this security protocol.
7. Don’t over-complicate your network.
A complex network is more likely to collapse than a simpler one because of all the unnecessary services and devices associated with it. As much as possible, keep your infrastructure simple. If, for example, you have a wireless connection that you don’t really understand the point of, just take it down. Unless it’s a staple in your business, it’s probably just making your network infrastructure weaker. Remember that most disasters happen through wireless communications. If you still decide that a wireless network will do you good, at least secure it properly so your whole infrastructure won’t be compromised when things get out of hand.
8. Protect your network inside and out.
To avoid cyber incidents that involve security breach, secure your network from the inside out. Tools that monitor how your network is used by employees are not difficult to find or set up. Better address the problem before it occurs. Virus and malware protection software are also recommendable. Sometimes, employees can be careless in their transactions. A backup plan is indeed indispensable here. There are other ways for you to shield your network from both internal and external vulnerabilities. Make use of all of them.
9. Combat problems before they come.
As a businessman, you should be interested not only about your company’s present network infrastructure. The future looms ahead, and it should also be one of your concerns. Create a security policy that underlines all the basic measures that you need to undertake to protect your network. Include even those points that are still unknown to you, especially in terms of network traffic. Define your perimeters and build a strategy that considers every possibility.
Securing your network infrastructure is not a one-time project. Yes, it has a definite start, but it never really ends. It’s a process of building and maintaining that goes on and on as long as your business continues to carry forward. (PA)
