Cloud security is the set of cybersecurity measures used to protect cloud-based applications, data, and infrastructure from unauthorized access, online attacks, and insider threats. Cloud security involves applying security policies, practices, controls, and other technologies to help secure cloud environments.
Cloud security is important because it enables organizations to benefit from the flexibility, scalability, and innovation of cloud computing while minimizing the risks of data breaches, compliance violations, and service disruptions. Cloud security also helps organizations meet their regulatory and legal obligations regarding data protection and privacy.
Cloud security works by following a shared responsibility model between the cloud service provider (CSP) and the customer. The CSP is responsible for securing the cloud infrastructure, such as servers, storage, networks, and virtualization. The customer is responsible for securing the data, applications, and user access in the cloud. Depending on the type of cloud service model used (IaaS, PaaS, or SaaS), the level of responsibility may vary.
Some examples of cloud security measures are:
- Identity and access management (IAM): This is a process of verifying the identity of users and devices and granting them appropriate permissions to access cloud resources. IAM helps prevent unauthorized access and enforce the principle of least privilege.
- Encryption: This is a method of transforming data into an unreadable format using a secret key. Encryption helps protect data from being intercepted or tampered with while in transit or at rest in the cloud.
- Firewall: This is a device or software that monitors and filters network traffic based on predefined rules. Firewall helps block malicious or unwanted traffic from reaching or leaving the cloud.
- Antivirus: This is a software that detects and removes malware from devices or systems. Antivirus helps prevent malware infections that could compromise data or functionality in the cloud.
- Backup: This is a process of creating copies of data and storing them in a separate location. Backup helps ensure data availability and recovery in case of accidental deletion, corruption, or disaster in the cloud.
