It's tempting to focus on the latest high-tech security tool but most infosec pros acknowledge that all those digital, cloud-based bells and whistles won't protect a network if the network security basics aren't in place. In the segments to this guide we cover basic first steps, touch on fundamentals like the importance of visibility even in the virtual age, while also peering into the future of network security. Readers of this guide should come away with a deeper understanding of network security basics and an overall "lay of the land" which it comes to securing the network.
1Network security first steps-
What network security basic steps do companies need to take now?
All the fancy new security tools are enticing but they're useless unless the infosec team has locked down the network security basics. Learn why initial tasks include establishing a network security overview, improving the quality of security alerts and boosting ransomware security awareness.
Rapidly changing environments, from sprawl to consolidation, increase the challenges of network risk analysis, proper segmentation, and policy and change management. Continue Reading
Workers demand access to their company's network anytime, anywhere -- making mobile network security a constant challenge for IT. Admins can turn to SDN and NFV technology. Continue Reading
Network security alerts are high in number and low in accuracy. Expert Kevin Beaver explains strategies security professionals can develop to overcome these obstacles to improving security. Continue Reading
It may sound like network security basics, but don't underestimate the power of proper segmentation and isolation as an effective way to protect your enterprise network from attack. Continue Reading
2Visible needs for networks-
Visibility: How to preserve a network security basic
The most basic need for network security is visibility into the network itself; you can't secure what you can't see. Learn how even in this complex age of mobility and cloud, IT network pros can maintain their network's visibility to keep it secure.
As networks become more complex, fundamental monitoring tools are losing their currency. But it's still possible to retain visibility and keep users happy. Continue Reading

3Beyond network security basics-
Whip-smart network security is possible. Here's how.
It's mind-boggling, the forces combining now to take network security far beyond the basics. Firewalls are integrating cloud-based threat information. Advances in machine learning are making tech tools designed to sense network threats ever more savvy. Current Defense Department projects on security mobile networks and devices will certainly lead to commercial applications. But while technological advances that help IT pros move beyond network security basics show great promise, they also bring their own challenges.
A DARPA project seeks researchers from academia and business to improve security for mobile networks and devices. The program could bring better tools for the enterprise. Continue Reading
Advanced machine learning can help distinguish between false alarms and real network threats, creating valuable time for IT employees. But the technology still faces challenges. Continue Reading

Pervasive security in place of layered security is needed to secure and defend modern networks from diverse cyber threats. Continue Reading
4Security with SDN-
Security considerations for software defining the network now
If network security basics are in place, a good next step for networking pros is to consider how to add software-defined networking to your setup. SDN can improve network functions but before and during implementation security must be foremost in mind. Learn how to get your network software-defined now.
Software-defined networking security has both good and bad potential. It can benefit route connectivity, but it also presents risk linked to improper SDN controller implementation. Continue Reading
