Cloud Security

Hybrid cloud computing offers extraordinary benefits for flexible deployment, scalable infrastructure and cost-effective use of resources. It also raises a number of data security issues. 

In a hybrid cloud model, data resides in a multi-tenant, software-defined compute, network and storage architecture. IT teams are responsible for securing their sensitive data across private and public clouds, addressing regulatory requirements, privacy concerns and data remanence issues. 

Encryption technologies essential. Virtual machine-level encryption provides a portable solution that’s agnostic to the infrastructure in a hybrid cloud and can secure virtual machines during migration. Encryption at the storage infrastructure level is also an option, providing an easy way to secure data that is transparent to the applications consuming storage in physical and virtual infrastructures. 

The key to deploying either approach to encryption is a robust key management solution that can ensure that keys remain in the control of data security administrators. That’s where Dell EMC CloudLink can help. 

Dell EMC CloudLink simplifies cloud security by providing policy-based key management and supporting multiple data-at-rest encryption options for virtual machines across a wide range of cloud platforms. Working with native OS encryption, CloudLink can protect VMs and sensitive data while meeting security, compliance and regulatory requirements. Along with best-in-class performance, CloudLink avoids the risks associated with proprietary encryption tools.

CloudLink enhances cloud security by providing:

• FIPS 140-2 certified encryption and key management
• A single management interface and REST APIs for greater ease-of-use
• Support for VMware, Microsoft and Amazon Web Services environments
• Flexible, full lifecycle key management in the cloud and on premises
• A lightweight CloudLink Agent that can be deployed seconds

By managing encryption and cloud security with Dell EMC CloudLink, you can:

• Enjoy independent control of data in public clouds and shared infrastructure.
• Choose the most appropriate encryption solution for your cloud security requirements from multiple VM-level and VxFlex OS device encryption options.
• Easily deploy encryption in new or existing applications without the need to re-architect the solution.
• Protect against data leakage from swap, configuration and temporary files with boot volume encryption.
• Avoid cloud lock-in and address data remanence with broad cloud support.
• Rely on trusted and familiar OS encryption tools for higher performance, complete application transparency and confidence that future OS versions will be supported.

What cloud security?

Cloud security encompasses security technologies, policies, procedures and controls that together protect cloud infrastructure and the applications, systems and data that run or reside on it. Threats to cloud security include malicious attacks that result in data breaches and theft, misconfigurations and leaks that inadvertently expose data and insider threats that result in cybersecurity breaches. 

What are the challenges of cloud security in a hybrid environment?

With a mix of public, private edge cloud resources, a hybrid cloud environment poses visibility and control challenges for IT teams as they seek to secure data. Compliance and governance can be an issue as well, as a heterogeneous mix of systems makes it harder to perform the tasks required for a security audit.  

How does Dell EMC CloudLink improve cloud security?

Dell EMC CloudLink simplifies cloud security by enabling IT teams to leverage a single key management solution for multiple environments, securing data across public, private and edge cloud platforms with confidence.
