How to Secure Your Business in a Multi-Cloud World

How to Secure Your Business in a Multi-Cloud World

Secure Your Business in a Multi-Cloud World: For many organizations, the cloud has become the single way to market for new application deployment. It affords greater agility and scalability, faster access, and higher performance to innovative technologies, which helps a business gain a competitive edge. As a result, applications and data now remain in a multitude of the cloud environment, including public and private clouds, spanning infrastructure, platform and software as a service – SaaS, IaaS and PaaS, respectively.

According to Gartner, multi-cloud strategies will be common for 70 per cent of enterprises by 2019. – {Gartner: The Future of the Data Center in the Cloud Era, David J. Cappuccio, 19 June 2015}

Despite this momentum, several barriers still slow adoption and security remain a top concern. Also, although native public cloud security controls provide some degree of access control and identity management, breaches are often the result of improper use, misconfigurations or advanced threats.

Confidently accelerating the move to the cloud requires consistent, automated protections across multi-cloud deployments that prevent data loss and business downtime. This brief highlights an innovative security approach that minimizes the wide range of cloud risks that can cause breaches, while enabling organizations to achieve consistent and frictionless cloud protections for multi-cloud environments.

Securing multi-cloud environments

Traditional cloud security approaches are Insufficient
There are several security options to choose from when moving to the cloud. However, the approaches widely used today have proven insufficient in providing a holistic view of the cloud required to detect and prevent advanced threats and data breaches.

Native Public Cloud Security
Cloud security is a shared responsibility between the cloud provider and the customer. In IaaS, customers are responsible for protecting their applications and data running within the public cloud, whereas in SaaS, they are responsible solely for the security of their data. To aid with protection, cloud service providers offer essential native security services, including access controls and data protection tools. However, the level of security doesn’t meet the requirements of the enterprise and is limited to only that cloud provider. Because organizations tend to use a variety of clouds, encompassing IaaS, PaaS and SaaS, fragmented security and management overhead often result.

Point Products
Using multiple security tools from multiple vendors to solve for specific use cases results in a fragmented security environment in which IT teams must manually correlate data to implement actionable security protections. This level of human intervention increases the likelihood of human error, leaving organizations exposed to threats and data breaches. For example, although useful to mitigate risks within SaaS environments, cloud access security brokers, or CASBs, have become another point security tool to administer, prone to human error and featuring operational complexity as well as increased costs that negatively impact IT administration overhead.

Legacy Network and Content Security
Security vendors today claim to offer the level of protection required to secure your cloud environments. However, what they refer to is often a virtualized instance of hardware placed in the public cloud. This approach is not truly security with cloud-integration, negating the on-demand nature of the cloud and agility benefits. Plus, it lacks the automation required to enable consistent, frictionless security across your entire multi-cloud environment.
