Cloud computing continues transforming how organizations use, store, and share data, applications, and workloads. Cloud Computing has also introduced a variety of security threats and challenges. With so much going into the cloud, public cloud servers, particularly these assets, become the natural targets for violators.
The Vice President and Cloud Security Leader at Gartner Inc., Jay Helser, states, “The volume of public cloud utilization is growing rapidly so that inevitably leads to a greater body of sensitive stuff that is potentially at risk.”
In contrast to what many people might think, the primary responsibility for protecting corporate data in the cloud is not within the service provider but only with the customer. Heiser says, “We are in a cloud security transition period in which focus shifts from the provider to the customer.” He states, “Enterprises are learning that huge amounts of time spent trying to figure out if any particular cloud service provider is ‘secure’ or not has virtually no payback.”
7 Cloud Security Threats
Data Breaches
A breach in data could be the primary objective of a targeted attack, or it might just result from human error, application failure, or inadequate security practices. It can involve disclosing any information not intended for the general public.
This information includes personal information such as health, financial, personality identifiable information, property information, or trade secrets. For various reasons, an organization’s cloud-based data might hold value to different parties. The data breach risk is not unique to that of cloud computing. However, it does consistently rank as number one when it comes to customers.
Insecure Interfaces and Application Programming Interfaces (APIs)
Cloud providers have exposed various software user interfaces (UIs) or APIs that customers can use to manage and interact with the cloud services. Provisioning, management, and monitoring are all performed using these interfaces. The security and availability of general cloud services depend on the APIs’ security. They should be designed to defend against accidental and malicious attempts to circumvent the policy.
Insufficient Identity, Credential, and Access Management
Violators impersonating legitimate employers, operators, or designers can read, change, and sometimes even delete data. They will also try to issue the control plane and management functions, sneak on data in transition, or even release malicious software that originates from a natural source. Consequently, inadequate identity, qualification, or acute administration can enable illegal access to data and hypothetically catastrophic damage to establishments or end-users.
Account Hacking
Account hijacking or hacking is one of the oldest kinds of cloud corruption. However, cloud services have added a new threat to the landscape. Attackers who access a user’s credentials can easily eavesdrop on numerous activities and transactions. They can also manipulate data, return falsified information, and redirect customers to illegitimate websites.
The account and service instances may become the new base used by attackers. With these stolen credentials, hackers might also gain access to critical areas of cloud computing services, allowing them to compromise their confidentiality, availability, and integrity easily. 
System Vulnerabilities
System vulnerabilities can be defined as exploitable system bugs that the attackers can easily use to penetrate a system for data theft, complete control of the system, and disrupt service operations.
Susceptibilities within the apparatuses of the operating system might put the security of all of these services, along with the data, at significant risk. With the introduction of multi-tenancy in the cloud, schemes from various establishments have been placed close to each other and given access to the shared memory with resources that create a new attack surface.
Data Loss
The data stored on the cloud might be lost for numerous reasons other than malicious attacks. Data could be lost due to accidental deletion by the cloud service provider or a physical catastrophe such as a fire. This might lead to permanent data loss unless the provider has taken measures to back the data up correctly.
Denial of Service (DoS)
DoS attacks have been designed to prevent users of this service from accessing the data and the applications. By compelling the targeted cloud service to ingest excessive amounts of finite system resources, such as processor power, network bandwidth, and disk space, the attackers might cause the system to slow down and leave all legitimate users without access to the system services.
