Cloud Security Maturing to Handle Virtualized and Software-Defined Infrastructure

January 08, 2016

The technology push toward mobility, applications and increasingly virtualized network architectures has put the spotlight on cloud security for 2016. And with good reason since some of the largest security breaches in history took place last year, many them within virtualized and cloud network environments.

According to MarketsandMarkets, the total market for cloud security will reach $8.71 billion by 2019, fueled primarily by a need to increase security while reducing capital expenditures. Indeed, the cloud demands a different approach to security and traditional legacy solutions simply aren’t equipped to handle the complexities of the virtualized, software-defined infrastructure powering the cloud.

A recent article published by SDxCentral highlights some of the security requirements necessary for cloud-based SDx architectures. The company has also identified a booming community surrounding cloud security, with a new breed of startup companies and tools steadily streaming to market and more than $500 million in venture capital flowing into the space.

The new crop of cloud security solutions addresses prevention at every entry point and attack vector, which must be automated and provided in real time. Threat resolutions should also be aggregated and shared publicly to curb unknown or malware attacks. Many new offerings are also being built directly into cloud and virtualized infrastructure as native software or on an as-a-service basis, enabling capabilities like analytics and SDN features.

Cloud security will only be as strong as corporate policies, and companies are being encouraged to create and enforce strong policies surrounding access control and segmentation of data. These policies may be protected via encryption, security tokens and two-factor authentication. Organizations also need to understand that human error and loopholes have been the culprits in noteworthy cloud attacks and that technology and automation can eliminate a wide range of vulnerabilities.

Transparency Market Research forecasts the market for cloud security will reach a whopping $11.8 billion by 2022, fueled by new and niche tools and solutions designed to deal specifically with the virtualized and software-defined infrastructure powering the cloud. New growth areas will include security information and event management (SIEM) along with real-time analytics generated by both hardware and applications. Intrusion detection systems (IDS) will also become more mainstream, monitoring network and system activities for malware and policy violations. Finally, as the cloud security market matures in 2016, tools designed to specifically handle virtualized environments will gain prominence, offering features like microsegmentation of network traffic and built-in analytics.

Day 4, Cisco Live! - The Wrap

Day 4 was the final day of our first ever Cisco Live! We had a great show, with many great conversations and new connections with existing and potential end users, resellers, partners and job hunters.

Day 3, Cisco Live!

Day 3 of Cisco Live is history! For Fiber Mountain, we continued to enjoy visits from decision makers and influencers who were eager to share their data center and structured cabling challenges.

Day 2, Cisco Live!

Tuesday was Day 2 of Cisco Live for Fiber Mountain and we continued to experience high levels of traffic, with many high value decision makers and influencers visiting our booth. One very interesting difference from most conferences I attend is that there are no titles on anyone's show badges. This allows open conversations without people being pretentious. I think this is a very good idea.

Day 1, Cisco Live!

Fiber Mountain is exhibiting at Cisco Live! In Las Vegas for the first time ever! Our first day was hugely successful from just about any perspective - from quantity and quality of booth visitors to successful meetings with customers.
