The Aspect of Security in Cloud Computing and the Necessary Solutions
Cloud computing exposes users to a unique range of issues and challenges related to the security aspect. The cloud technology ensures that data remains stored with a third-party provider. Users are allowed to access data over the Internet. In other words, cloud offers limited visibility and control over data, explains IT professionals based in London.
Security measure in the cloud computing environment is a shared responsibility, explain professionals, who form a highly recommended IT support team in London. The cloud service provider takes up the responsibility for the security of the cloud itself, while customers cover the security and integrity of the data that they store in cloud. Every cloud-based service that exists, including Software-as-a-Service (SaaS) like Microsoft Office 365 to Infrastructure-as-a-Service (IaaS) like Amazon Web Service, a customer has to take up the responsibility of keeping his data protected from unauthorised users as well as controlling access to it.
The greatest concern in cloud computing is maintaining data security. In the following paragraphs, let us discuss some of the major security-related issues in SaaS, IaaS and private cloud.
Security-related issues common in SaaS (Software-as-a-Service)
- Poor visibility of the data those are stored in the cloud
- Unethically accessing and stealing of data from the cloud environment by malicious users
- Poor control over defining users, who can access sensitive data
- Inefficiency in monitoring data while on transit to and from cloud applications
- Cloud applications placed outside the scope of IT visibility (example, shadow IT)
- Shortage of skilled and knowledgeable staffs to manage the data security aspect in cloud environment
- Inefficiency in preventing misuse of data by insiders
- Inefficiency in maintaining regulatory compliance
- Inefficiency in accessing security measures of the cloud application-provider
As far as the SaaS application is concerned, the issues are mostly related to the data and its access. As a customer, it is your responsibility to have a clear understanding of what data you place in cloud and who in your organisation can access that data. In addition to that, you should also know the level of protection your cloud service-provider has applied to safeguard your data.
Security-related issues common in IaaS (Infrastructure-as-a-Service)
- Lack of complete control over who can access your sensitive data
- Cloud accounts and workloads that are created beyond the IT visibility (for example, shadow IT)
- Stealing of data hosted in cloud by malicious users
- Shortage of skilled and knowledgeable staffs to ensure security in the cloud infrastructure
- Low visibility into the data that are hosted in cloud
- Lack of efficiency in preventing misuse and stealing of data by insiders
- Insufficient security control over on-premises and multi-cloud environments
- Difficulty in monitoring cloud workload systems and applications for risks and weaknesses
Data protection is a critical task in the IaaS application. As a customer’s responsibility in this application extends to aspects like applications, operating systems and network traffic – additional threats to security automatically crop in.
Security-related issues common in private cloud
- Shortage of skilled and knowledgeable staffs to shoulder the security aspect for a software-defined data centre (like virtual compute, network, storage)
- Insufficient visibility over the security aspect for a software-defined data centre
- Preventing the latest attacks and threats
- Insufficient security control across traditional servers and virtualised private cloud infrastructures
- Spiraling complexity of infrastructure that demands more time and effort in implementation and maintenance
Private cloud environments offer extensive control and this control plays the crucial factor in the decision-making process related to allocation of resources between a public and private cloud. Usually additional levels of control and protection in private cloud can easily compensate for the other limitations. The compensation is so handsome that it often prompts users to make the transition from monolithic data centres that are totally based on servers.
Reducing security risks in cloud computing environment
These days many business organisations are using cloud services. In fact, for many of them cloud computing is not the primary strategy for their IT (Information Technology). To reduce risks related to cloud computing, organisations should better work on the strategies discussed below.
- DevSecOps processes: DevOps and DevSecOps not only improve code quality but also reduce the chances of exploitation and vulnerabilities. Moreover, they contribute to speedy application development and feature deployment.
- Automated application deployment and management tools: Ever-increasing security threats combined with shortage of staffs skilled in the data security aspect is the main challenge to deal with. Automation not only eliminates routine, humdrum tasks but also increases human advantages with machine advantages and this is the subtle approach to all modern IT operations.
- Unified security with centralised management: It is not possible for one vendor or a product to deliver everything. A unified management system based on the approach of open integration brings the necessary parts together to streamline the workflow and reduces the overall complexity.
