Software-defined Security – Understanding next-gen technologies

Modern security technologies must incorporate new services models, new ways to protect the user, and better ways to control mobile traffic. The proliferation of cloud computing and IT consumerization has created a new layer of data which flows through the WAN. Here’s the reality – traditional means of security your infrastructure is no longer enough. Hardened appliances sitting at the core provide some critical services – but what about that cloud layer? What about virtualization? How can the modern security environment better protect the evolving user?

Let’s take a look at some numbers in mobility and data growth. According to the latest Cisco Visual Networking Index report, mobile data traffic will reach the following milestones within the next five years.

  • Monthly global mobile data traffic will surpass 15 exabytes by 2018.
  • The number of mobile-connected devices will exceed the world’s population by 2014.
  • Monthly mobile tablet traffic will surpass 2.5 exabyte per month by 2018.
  • There will be more traffic offloaded from cellular networks (on to Wi-Fi) than remain on cellular networks by2018.

All of this creates new concerns around where this data is stored, how it passes through a data center and how it is being securely delivered to the end-user. This is where the concept around software-defined security comes in to play. Effectively, we are completely abstracting the security layer to create new types of services which can live anywhere within an infrastructure. We’re able to place IPS/IDS services inside of a network and deploy entire virtual security appliances at the edge and the core.

Remember, these virtual systems aren’t here to replace existing physical appliances. These are critical systems with dedicated ports which are required to process a massive amount of information. However, a necessary compliment has certainly become the virtual layer in the security world. Next-generation firewalls create that software-defined security layer that allows administrators to create a more powerful security platform.

For example, security products from Checkpoint allow you to deploy virtual appliances and services throughout your cloud and localized network infrastructure. These services proactively monitor your network to ensure critical data points stay secure. Another is example is the evolution of the logical security operating system. Palo Alto created their PAN-OS security-specific platform to safely enable all applications, regardless of ports, protocols and evasive tactics, protects you against all known and unknown threats, and integrates layer 1-3 flexibly in the virtualized environment.

These next-generation security technologies are created to optimize and better secure your evolving infrastructure. When creating a distributed data center or cloud model – it’s important to establish secure links where data can flow securely. In creating that type of architecture – make sure to look at next-generation firewalls, software-defined security, and all of the powerful virtual security services that can continue complement your environment.
