How does Cloud Security work? 

Cloud Security involves everything (technology stack, controls, policies, and all processes) that come together to protect a cloud environment. Cloud Security is always curated according to the requirements of an organization and is never a one-size-fits-all solution. Here we will try to dissect the important core aspects of Cloud Security and try to understand how different components work together in establishing comprehensive cloud security. 

If you are interested in advancing your career in Cloud Security to managerial positions, then check out this CCSP Course to help you achieve your goal. Back to the topic, there’s no single way of explaining how Cloud Security works or functions. Instead, several strategies are there that will help you achieve robust security. Let’s discuss them one by one to understand each of these strategies and tools: 

Identity and Access Management

All companies must have an Identity Access Management or IAM system that will help them control access to information. An IAM combines multi-factor authentication with user access policies. This then is used to decide the level of access that each employee must have, how much they can access, and what they can edit or make changes to.

Gather intelligence, monitor, and prevent

Businesses that hold sensitive information deploy Intrusion Detection Systems (IDS), Threat Intelligence, Intrusion Prevention Systems (IPS), etc. Systems like these will help companies identify hackers who are or will be a potential threat in the future. These systems are relied upon to mitigate attacks and alert you in time. Read this CCSP Tutorial for Beginners to help you understand how to get CCSP certified. 


Encryption is the process of protecting your data by encoding them at rest and while in transit. It puts hackers at a disadvantage as they now couldn’t decipher without a decryption key. Encryption is one of the key strategies that help ensure Cloud Security is intact.

Cloud Vulnerability and Pen-testing

Cloud Security’s other major practice is vulnerability checking and pen-testing or penetration testing. In this practice, the cloud infrastructure is put to test to identify any loopholes, potential weaknesses, etc. Once these tests are complete several solutions arise that can then be implemented to improve the overall security. 


This practice is gaining popularity lately among cloud service providers. This practice divides cloud deployment into separate security segments down to the individual workload level. The biggest benefit of this Micro-Segmentation is that you can apply flexible security policies to individual workloads thereby minimizing loss in case of a Cyberattack. 


Firewalls were an underrated security solution to protect sensitive data. Cloud Service Providers maximized the usage of these firewalls. Today, the firewalls are also modernized and well equipped with all the functionalities that will help businesses secure data from hackers. 

Physical Security 

It’s one of the most important and essential practice that helps Cloud infrastructure to remain safe in the first place. Many measures are comprehensively comes under Physical Security. These are CCTV, uninterrupted power supplies, no direct access to hardware, fire protection, etc. 


These are all some of the major Cloud Security components that help them secure and protect the data stored over cloud from illegal activities from cybercriminals. Hope this article helped you understand how Cloud Security works in an overview.
