Cloud Security is All About Traffic Visibility and Control

    Posted by Nubeva on Jan 4, 2018 9:26:00 PM

    When it comes to security in the cloud, organizations are putting their blind faith in the cloud providers to secure their assets. Without access to the infrastructure, they cannot apply on-premises security tools and policies in the cloud. By unlocking access to the traffic, organizations can regain visibility and control in the cloud, and leverage their existing investments to manage across hybrid environment.

    As organizations of all sizes and industries are moving to the cloud to accelerate business agility, security concerns remain as the primary barrier to cloud adoption.  According to the Hybrid Cloud Environments: The State of Security report by Alogsec, the number one security challenge for organizations is a lack of visibility into security in the cloud, followed closely by the need to manage security policies consistently across hybrid environment.


    You Can’t Secure What You Can’t See

    Unlike your own datacenter, you don’t have full access to the cloud environment run and operated by third-party providers such as Amazon Web Services and Microsoft Azure. If you think the cloud providers would secure your workloads and applications, you are in for a big surprise. Cloud providers typically don’t protect anything above the hypervisor layer, so security is mainly your responsibility. The Cloud Security Alliance (CA) clearly stated in its Treacherous 12 Top Threats to Cloud Computing Plus: Industry Insights report that “Cloud providers often have good security for aspects they take responsibility for but, ultimately customers are responsible for protecting their data in the cloud.”

    You may ask “If I don’t have access to the cloud environment, how am I going to secure my assets?” This is the quandary of protecting yourself in the cloud: you can’t secure what you can’t see. Therefore, gaining real-time visibility is paramount. Having full visibility in the activities inside the cloud is necessary to allow you to enforce policies and put control back into your own hands.


    Full Traffic Packet Capture Gives You Complete Cloud Visibility

    The dynamic nature of the virtualized cloud environment makes it extremely difficult for security teams to see what’s happening inside. Traditional on-premises monitoring tools don’t work in the cloud simply because of the lack of dedicated physical host or network to connect those monitoring devices or probes.

    While cloud providers offer basic metrics on resource utilization, availability, topology or events, they generally lack sufficient context and intelligence on network activities for real-time operational monitoring and threat detection. SIEM tools collect flow logs, traps and alerts to offer analytic metrics. Similarly, they do not capture actual traffic flow among virtualized resources. Several vendors offer agent-based tools today to capture cloud traffic. However, these tools introduce management overhead and do not work in environment where there are no host such as PaaS and virtual networks.


    Unlock Traffic Visibility and Control with Nubeva

    One solution that can capture full traffic packet in IaaS and PaaS environments is Nubeva StratusEdge. Steve Perkins, Nubeva’s Chief Marketing Officer, describes in this video that Nubeva StratusEdge gives you complete traffic visibility and control in the cloud by unlocking the ability to see packet traffic between virtual machines, networks, and even platform services such as .NET/PaaS without agents. It can be deployed in your private account as VM instances and inserts “in-line” as network tap between the source of communications and the destination.

    In addition, Nubeva allows security teams to run next-gen firewalls or entire security technology stacks without functional compromise, inside their Azure and other cloud environments, just as they do in their private data centers. They can extend their existing on-premises security investment and policies to the cloud.


    Key Takeaways

    If you can’t quickly and accurately see what’s going on across your cloud environment at all times, you run the risk of not knowing when you’re being attacked or compromised. Hence, you need continuous traffic visibility inside the cloud, and the ability to ‘insert’ security control points. These are critical steps toward improving your security posture, especially when you’re dealing with the dynamic, elastic nature of modern cloud computing environments.
