Cloud Security - Protect Your Data and Infrastructure
What is Cloud Security?
Cloud security also known as cloud computing security includes sets of policies, controls, procedures, and technologies that work together in order to protect cloud based systems, data and infrastructure.
Why is Cloud Security important?
Cloud computing gives companies access to the next level - next-level customer service by ensuring enhanced data gathering and storage, next-level flexibility through remote working and fast scalability, next-level convenience through interconnected systems with fast file and data sharing.
There are certain risks of misconfiguration and the ever-present danger of cyber criminals, for any company's cloud environment to retain effective security. That's where cloud security comes into the picture. With cloud security, you can improve the level of protection for your digital assets and mitigate the risks associated with human error, reducing the likelihood that your organization will suffer a damaging loss thanks to an avoidable breach.
Who is responsible for Cloud Security?
There is a shared responsibility model for cloud security. Your cloud hosting provider is not on the hook for compliance or security – you are. Many security breaches are due to over-reliance on vendor security for recent breaches. Organizations should depend on their vendor for availability, but understand and execute their own security and compliance obligations.
What are the Cloud Security challenges?
Cloud has grown and evolved as a technology to encompass an array of core and associated products and services. Public, private, and hybrid are just the bare infrastructure essentials, as apps, DevOps tools, containers, microservices, and third-party SaaS platforms continue to proliferate. Cloud security is complex and can introduce uncertainty for IT professionals charged with securing expanding cloud footprints in their organizations. And with remote work becoming the rule rather than the exception, scalability has become yet another immediate cloud management challenge for organizations.
Some of the top cloud security challenges IT security professionals face today include:
- Scaling security to meet the needs of a growing remote work force
- Consolidating and centrally managing security
- Eliminating cloud security blind spots
- Protecting hybrid cloud
- Coordinating multi-cloud security
- Containing shadow IT and “rogue” device risks
- Extending security to future cloud: DevOps, containers, and tools
- Slow response to attacks
To address these challenges, you need to have fast, cost-effective deployment that controls remote access, cloaks fundamental core business systems and limits disruptions to critical operations.
What is the Cloud Security use case?
Cloud security is a shared responsibility across vendor providers and the customer. Your IT organization should also provide security oversight. You need to deploy consistent cloud security policies ensuring that all connections are secure by using encrypted and extended protection of all segmentation levels.
Security is also closely entwined with how cloud infrastructure is used. Every component of cloud has distinct security requirements — compute, VM, storage, network, containers. And each infrastructure component has its own unique security requirements.
A comprehensive, holistic, “monitor, detect, and respond” posture is necessary across any/all cloud platforms. Unisys Stealth® can secure your hybrid and multi-cloud environments without impacting your business. Explore the Cloud Security Use Case
What are the different types of Cloud Security frameworks?
World’s IT professionals need to consider three cloud security frameworks:
- International Organization for Standardization (ISO): International standards that provide exhaustive checklists to consider when establishing a new system. ISOs 27017 and 27018 in particular deal with cloud security.
- National Institute of Standards and Technology (NIST): A US-based body of international standards that provides both framework checklists for establishing a new system as well as numerous articles on specific problems.
- Cloud Security Alliance (CSA): A more operational set of standards that provides very detailed questionnaires and self-assessment forms to help audit third-party vendors and your own systems, to the technical level.
Securing your cloud ecosystem
Cloud security failures are often due to inadequate security practices, outdated policies, weak procedures, and misconfiguration errors.
- Increased attacks
- Disjointed computing environment
- Vulnerabilities from VOIDS
