The implementation of efficient security controls for cloud-based systems is crucial to assurance of the confidentiality, integrity, and accessibility of sensitive data and undertaking large-scale data storage. The internet and cloud computing share a symbiotic relationship. To manage the inherent security risks connected with the internet and in turn cloud computing, the process calls for a thorough understanding of cloud architecture, risk management, and industry best practices. Additionally, modern security approaches like Zero Trust, confidential computing, and AI-driven threat detection have become integral to cloud protection strategies.
Introduction
The evolution of web has gone hand in hand with the increase in the amount of data storage requirements. The early days of internet had low requirements as the data was primarily in text format. Over time, with the increase in the use of social media, formats such as audio, images, videos, etc. increased and required a new solution for the increased data size. What was once called Big Data has now evolved into advanced frameworks like data lakes, data meshes, and AI-driven analytics, reflecting the shift toward more intelligent data architectures. Large scale server racks in companies served the purpose of data storage, security, and administration. However, these servers have high maintenance and cost both in terms of their physical space as well as software management for them. Businesses recognized cloud-based solutions as a good fit to meet these requirements.
Cloud adoption in 2025
Today, most enterprises have adopted hybrid or multi-cloud strategies rather than seeing the cloud as a novel solution. A single-cloud company is able to effectively serve the needs of many companies at the same time by renting their servers using the medium of internet. The organization renting these cloud-based systems can then focus solely on its actual business requirements. That is primarily the reason the cloud-based systems have gained precedence in the world.
Cloud-based systems rely heavily on the security mechanisms they provide to their vendors. Security controls with cloud-based systems constitute the practices, guidelines, and procedures that help safeguard the cloud, which is majorly shared using the internet for data communication. A number of important functions are performed by cloud-based systems. To summarize a few, these include the implementation of security controls, ensure availability, confidentiality, integrity, and reduce potential risks. It also includes various security controls, including identity and access management, logging and monitoring, data encryption, network security, incident response, service provider security, security awareness and training, vulnerability management, data backup and recovery, and regulatory compliance. Some of the major features that are considered a necessary part for a robust cloud-based systems are as below (Cohen, 2021; Exabeam, 2022):
Centralized visibility
Cloud security control essentials involve centralized visibility into security policies, user activity, configuration settings, and hidden risks in online data stores, reducing the chances of overlooking vulnerabilities or attacks. To address the challenge of different cloud configurations chosen by non-security experts, security teams require centralized visibility that integrate with cloud management and security systems. These tools enable monitoring, detecting misconfigurations, assessing configuration status, issuing alerts, providing recommendations, and identifying compliance issues in the cloud environment. This visibility now increasingly leverages AI-driven analytics to detect anomalies and potential threats in real time. Gartner predicts that in the near future, “99% of cloud security failures will be the customer’s fault”.
Native integration
Effective cloud security necessitates native integration into cloud management and security systems, as visibility into security posture across multiple clouds requires coordination with underlying cloud environments through API-level integration. This integration involves tools like Amazon Inspector, VPC Flow logs, GuardDuty for AWS, Stack Event and Flow Drivers for Google Cloud Platform, and Security Center for Azure. In addition, newer services like AWS Verified Access, GCP Security Command Center Premium, and Azure Defender enhancements have improved cross-cloud security posture management.
Security Automation
In light of the cybersecurity skills gap, enterprises are advised to automate their security functions to mitigate vulnerabilities. This can be achieved through plugins that enhance visibility and enable automation in multi-vendor ecosystems, as well as the use of security configuration scripts from providers to streamline security operations and adapt to evolving application changes without manual policy updates. Modern automation also integrates with cloud-native application protection platforms (CNAPP) and CI/CD pipelines, enabling proactive security for containerized and microservice-based workloads.
Threat intelligence feeds
Cloud security controls that leverage threat intelligence are essential for identifying attack patterns, providing insights on attackers, and enabling effective response and mitigation. As cloud environments grow in complexity due to multiple providers, a comprehensive solution that consolidates all cloud services under one umbrella is crucial for maximum security. It is advisable to choose providers offering dynamic threat intelligence feeds and solutions informed by comprehensive data collected from deployed sensors. Threat intelligence today is often AI/ML-powered, correlating attack data across multiple platforms for predictive analysis.
Types of Risks and Security Controls
Depending on the various stages in which data is involved, cloud-based systems establish different control mechanisms that can broadly be categorized into four types. Cloud security risks are prevalent, with a majority of organizations lacking sufficient security measures to protect their sensitive data in the cloud. Common pitfalls include unauthorized access due to the difficulty of controlling who can access cloud-based resources, the risk of account hijacking through weak passwords, limited visibility into cloud infrastructure owned by third parties, and the increased likelihood of cyberattacks targeting cloud-based data.
Deterrent controls warn and discourage attackers from targeting the cloud system through measures like background checks and strict consequences for cybercrime. Preventive controls strengthen the cloud’s defenses by removing security flaws, implementing multifactor authentication, and enhancing user authentication systems. Detective controls identify and respond to security threats by using intrusion detection software and security monitoring tools. Finally, the corrective controls mitigate the impact of attacks by rebooting systems, backing up data, and isolating compromised servers.
Cloud Security Frameworks
To meet these security requirements, companies make use of cloud security frameworks. Cloud security frameworks provide guidance and controls for securing cloud environments, benefiting both customers and cloud service providers (CSPs) by establishing a common understanding of security measures. These frameworks serve as a reference for discussing security practices, help in evaluating CSPs, and enable efficient customer vetting by providing a baseline for assessment criteria. By adopting frameworks, both CSPs and customers can streamline their security efforts and reduce the need for individualized evaluations and questionnaires.
Depending on the functional requirements, they can be majorly classified into few categories such as:
- Cloud Security Posture Management – CSPM
- Cloud Workflow Protection Platforms – CWPP
- Cloud Access Security Brokers – CASB
- Cloud Infrastructure Entitlement Management – CIEM
- Static Application Security Testing – SAST
- Cloud-Native Application Protection Platforms – CNAPP (newly emerging)
- Kubernetes Security Posture Management – KSPM (for containerized environments)
While this list is non-exhaustive, the categories cover in majority the types of security controls that are enabled by cloud-based security frameworks.
Cloud Security Comparison: AWS | GCP | Azure
AWS by Amazon, Google Cloud by Google and Azure by Microsoft have emerged as the largest providers of cloud services for cloud-hosting services. Their services are majorly divided in terms of:
- Infrastructure as a Service – IaaS
- Platform as a Service – PaaS
- Software as a Service – SaaS
PaaS includes Identity management, firewall rules, encryption, etc. SaaS includes rules and regulations including standards such as ISO 27001, PCI, etc. Each of the vendors has their own tools for meeting these standards, for example, Azure has Azure Security, GCP has Trust and Security Center, and AWS has Amazon Inspector. For IaaS, Azure has DDOS Protection, AWS has Shield, and GCP has Google Cloud Armor. Recent updates also include confidential computing solutions like Azure Confidential Ledger, AWS Nitro Enclaves, and GCP Confidential VMs. The functionality also includes password and key management such as Key Vault in Azure and Secrets Manager. Each of these vendors has a number of such services that work with each other to provide an efficient cloud security mechanism.
In addition to the three major vendors, there are also a number of other companies that focus on providing third-party cloud security services. The requirements of a company in terms of storage, domain, security, administrative roles, etc. play an important role in determining the choice of cloud security. Some of the major names in the cloud security domain include:
- CloudFlare
- CrowdStrike Falcon
- Qualys
- Splunk
- CyberArk
- Zscalar
- Cisco Systems
- Orca Security
- Wiz
- Lacework
- Palo Alto Prisma Cloud
