Cloud computing training equips you to implement cloud security measures with these crucial reasons in mind.
How Does Cloud Security Work?
Cloud computing security is typically implemented on various levels.
- Organizational level: The organization deploys software and tools to ensure the security of the cloud infrastructure used within the organization. It also includes any PaaS or SaaS offered by the organization to consumers.
- Cloud service provider level: The firm that provides cloud services, such as DropBox, Google, Microsoft Azure, Amazon Web Services (AWS), etc., implements cloud security to protect its servers and services. Their end users are also recommended to ensure further security measures, but these are optional and at their discretion. This is also called the shared responsibility model.
- Individual level: Everyone uses the cloud for personal and professional use. They can employ password managers, automated data back-up, and third-party security software to protect their cloud storage.
Cloud security is a multi-layer process involving all the business sections. The primary aspects include:
- Securing the server: Unlike traditional servers, the data traffic is first transmitted to the cloud. Hence, any unauthorized and direct access to the server is prevented when the cloud verifies the credentials and legitimacy of the traffic.
- Data inspection: Multiple filters and tools exist to inspect data before they reach the application through the cloud. The advantage is that the filters are universal; hence, no data from anywhere in the world can get a random pass to the application.
- Data encryption and management: The cloud manages crucial information stored in an encrypted form. However, data from multiple sources and formats that can potentially crack the encrypted data can get uploaded to the cloud. Hence, the cloud has tools that can recognize unusual formats and prevent their access to the rest of the storage.
- Separation of private and public clouds: Cloud security enables the separation of private and public clouds within an organization. Additional authentication and access safeguards are implemented to allow selective access to the private cloud that may hold sensitive strategic information.
- Compliance: Cloud computing security measures are created to comply with all the laws and regulations. They organize and manage data in a way that prevents illegal access.

Types of Cloud Security
Depending on the functionality of the application or platform, the type of cloud security deployed may change. Let’s look at the main types of cloud computing security.
Identity and Access Management (IAM)
Identity and access management (IAM) is a pool of services and tools for managing users’ identities and access. IAM creates digital user identities, including login credentials. As a cloud security professional, you may work on establishing the guidelines and procedures to be followed and the information required to allow genuine access attempts and flag illegal intrusions. It enables organizations to monitor user activity and enforce enterprise-level policy protocols for access and use both on- and off-site.
Security Information and Event Management (SIEM)
SIEM combines multiple software that help automate frequent tasks such as monitoring, identifying, responding, and logging threats. SIEM is especially useful if you are a part of the IT team that monitors and manages the cloud security infrastructure of an enterprise. This type of cloud security utilizes AI-based technologies to flag common threats and raise the alarm for particularly unusual intrusions.
Data Loss Prevention (DLP)
Data loss prevention is probably the most important type of cloud computing security. It comprises all the measures to protect data and its encryption, ensure its longevity, enable secure transmission, and allow regular backup. The motive is to prevent the loss of data by any means.
Public Key Infrastructure (PKI)
PKI enables authentication for applications and protects data during transmission. It is the framework for allowing digital certificates to verify the authenticity of the information. This helps confirm the user credentials when the data is accessed or approved from a remote location.
Business Continuity and Disaster Recovery
This type of cloud security focuses on maintaining the flow of business operations even if there is a cyber-attack on one or more of its features. It involves redirecting the data transfer away from the breached application to another storage space that can be accessed and used for going about the daily tasks of the business. You may also work on implementing tools to recover the data and applications rapidly and restore them to their optimum condition.
The Biggest Advantages of Cloud Security
We have established that cloud computing security is important, and there are several ways to utilize it. Now, let’s go through a list of the biggest advantages of cloud security:
In-built Features
Cloud security enables the integration of security features for the server, applications, platforms, and infrastructure even before they reach the end user. The professionals work on building multiple layers and codes into the design of the cloud applications. The cloud is reinforced with threat detection, auto-encryption, and loss prevention features in its architectural framework itself.
Centralized Control
Cloud security enables centralized control of the monitoring, analyzing, and managing the networks, devices, platforms, and systems. It also helps apply the same security standard to all cloud systems, irrespective of their configuration.
Lower Costs
Cloud computing security reduces the investment required for protecting physical servers and systems. The basic cost remains the same, and the only additional cost may be the upscaling and including more features in the security module. Further, the measures designed for the cloud apply to all the users, thus avoiding the costs for individual customization. A cloud computing security professional can also design the cloud so that users get a basic security framework in their subscription.
Improved Reach
A cloud security professional can monitor and assess an interconnected cloud ecosystem The integrated stack helps visualize the transactions occurring throughout the spread of the cloud usage. This helps the professional in detecting and responding to threats faster. For example, suppose the professional sees an anomaly in the data transfer occurring in mainly Linux systems. In that case, they can flag the issue in all the Linux users worldwide and nip the problem in the bud.
