What is Cloud Security?
Cloud security is the security of the data, applications and infrastructure involved in cloud computing. Many aspects of security for cloud environments (whether public, private or hybrid cloud) are the same for any basic IT architecture.
High-level security concerns -- such as unauthorized data exposure and leaks, weak access controls, susceptibility to attacks, and availability constraints -- affect traditional IT and cloud systems alike. Like any computing environment, cloud security involves maintaining adequate preventive security for you to:
Know that the data and the system are secure.
View the current status of the security.
Get checked immediately if anything unusual happens.
Can detect and respond to unexpected events.
Why is cloud security different?
While many people understand the benefits of cloud computing, they are equally baffled by the security threats. It is a dynamic environment where things are always changing - such as security threats. The thing is, for the most part, cloud security is IT security. Once you understand the specific difference, the word "cloud" doesn't sound like un-secure.
Why Cloud Security?
Cloud computing resources are distributed and highly interdependent, so a traditional approach to security (with an emphasis on traditional firewalls and securing the network circle) is no longer sufficient. Cloud computing enables dynamic use of shared resources by automatically provisioning storage, network and computing resources on demand basis. In addition, the cloud environment is increasingly connected,
Due to which it becomes difficult to maintain the secured circle. While this less firewalled approach has many advantages, it can also increase security risks by increasing the potential attack surface. The best cloud security plans allow companies to take advantage of the benefits of cloud computing, while also minimizing the risks.

Cloud computing creates many other specific security issues. It is difficult to identify users when virtual machines are running continuously and addresses and ports are assigned dynamically. Furthermore, in public cloud environments, a multilayer environment means that one organization shares its data with other organizations. Thus, it is important for public cloud providers to keep tenants separate.
What are the benefits of cloud security?
Cloud security offers a variety of benefits including:
Security from attacks: A primary purpose of cloud security is to protect enterprises against hackers and Denial of Service (DDoS) attacks.
Data Security: Robust cloud security protects sensitive data as well as protections like encryption from falling into the wrong hands.
Better availability: Many cloud security services provide live monitoring and support, which improves availability apart from addressing security concerns.
Increased reliability: A thoughtful cloud security approach includes built-in redundancy, leading to a more reliable experience.
Regulatory compliance: It can be difficult to ensure that a complex cloud architecture meets industry regulatory requirements. Cloud providers help ensure compliance by providing security and support.
How does cloud security work?
Cloud security covers a wide range of tools and practices, so there is no single explanation for how it works. The most important function of cloud security is to ensure that only authorized users access the data stored in the cloud. Enterprises use a number of tools and strategies to achieve this, including:
Micro-segmentation: This security technique divides the data center into different security areas with different workload levels. This allows IT to define flexible security policies and minimize the amount of damage attackers can cause.
Next generation firewall: More effective and better than traditional firewalls, the next generation firewall uses application-aware filtering to keep out advanced threats.
Data Encryption: This process encodes the data so that a key is required to decipher it, thereby preventing it from falling into the wrong hands.
Intelligence information, surveillance and prevention: These capabilities scan all traffic to identify and block malware and other threats.
Division of Cloud Security Responsibilities
Most of the cloud providers try to create a secure cloud for the customers. Their business model hinges on preventing breaches and maintaining public and customer trust. Cloud providers may try to avoid cloud security issues with the service they provide, but cannot control how customers use the service, what data they add to it, and who has access. Customers can weaken cybersecurity in the cloud with their own configuration, sensitive data, and access policies. In each public cloud service type, the cloud provider and cloud customer share different levels of responsibility for security. By service type, they are:
Software-as-a-Service (SaaS) - Customers are responsible for protecting their data and user access.
Platform-as-a-Service (PaaS) - Customers are responsible for securing their data, user access and applications.
Infrastructure-as-a-Service (IaaS) - Customers are responsible for securing their data, user access, applications, operating systems, and virtual network traffic.
