cloud computing issues and solutions
 

Introduction

Cloud computing is an internet-based, evolving technology that is becoming more prevalent in our society, especially in fields such as computer science and information technology that involve large-scale network computing. Cloud storage is a decentralized pool of resources that is gaining traction thanks to its low cost, high availability, and high output. Along with its many advantages, cloud storage presents a much more difficult situation in terms of data safety, data security, authenticated entry, and so on. Because of these issues, cloud computing implementation is getting more complicated in today's world. Various security concerns surrounding data protection and stability, as well as key factors impacting cloud storage, have been presented in this post, along with recommendations on specific areas. This article will highlight the cloud computing security issues and solutions to ensure maximum security. 

Cloud protection refers to the security policies, controls, and technology used to safeguard cloud computing environments. These controls can be categorized into three categories:

Preventative Controls:

These controls are a type of control that is used to prevent problems from occurring. This cloud computing security issues and solutions protection controls aim to reduce risk and plug security holes in the cloud infrastructure. Firewalls, security solutions, and secure device use policies are examples of this.

Controls for Detection 

These controls monitor ongoing or recently concluded assaults, allowing automatic or manual remediation to begin. Detection c could include things like security information and event management (SIEM) solutions (which are often distributed through SaaS models), anti-virus/anti-malware scanning software, and even managed network security monitoring.

Corrective Actions 

These controls are intended to repair the disruption or detrimental impact caused by an attack after it has occurred. Corrective controls may include things like remote data backups (to recover corrupted or compromised files), virus/malware removal software, and controlled security incident management services.

Cloud Computing Characteristics

On Demand Self-Service: 

It is a service that allows vendors to provision cloud services on demand or whenever they are required, such as network storage and service time, without the need for human intervention.

Broad Network Access: 

Services are available over networks and are retrieved using a structured framework that enables the use of several channels (workstations tablets, laptops, mobile phones).

Resource Pooling: 

The cloud provider's resources are shared on the server. Different services are allocated to customers, which may be physical or cyber. Consumers generally have no idea where the services they use are located, even at a high degree of abstraction such as state, region, or data centre.

Rapid Elasticity:

Services may be launched and monitored on an elastic basis; for customers, services available to them can tend to be limitless and can be scaled in quantity at any time.

Measured Services: 

Cloud systems are built in such a way that they can monitor resource consumption, such as encoding, bandwidth, and active user accounts, as well as storage, to provide access to both providers and consumers. Therefore, cloud computing security issues and solutions are top priority.
They can maximize resource use by holding a check by metering capabilities at any level of abstraction.
 

CLOUD SERVICE MODELS

Following service models are defined by NIST which includes three categories

  • Infrastructure as a Service (IaaS)
  • Software as a Service (SaaS)
  • Platform as a Service (PaaS)

Infrastructure as a Service (IaaS): 

IaaS is all about supplying end users with virtual machines, operating systems, and networks. Other computing capabilities are also provided in IaaS, such as the ability for customers or clients to instal any operating system or applications on virtual machines. Clients can only manage the operating system or applications that they are using, but they lose control of the infrastructure that they are using.

Software as a Service (SaaS):  

In this case, the customer is limited to accessing the vendor's apps, which are hosted on cloud servers. Many other clients may still access the same programme via a standard mechanism, such as a web browser or email. Clients or customers have no influence over the program or underlying infrastructures, such as the network server or the operating system.

Platform as a Service (PaaS):

The client will build their own desired application using a programming language and related libraries in PaaS. The provider supports certain languages or libraries. The user's requested programme is created and then installed on the vendor's server. The user may also customise his or her programme or adjust the configuration settings later. While cloud storage seems to be enticing, it comes with a slew of threats and security concerns, like data leakage, data destruction, hacker assaults, and malicious insiders.

Factors Affecting Cloud Security

Since cloud computing is surrounded by too many innovations, such as load balancing, network, concurrency control, virtualization, operating system, database, memory management, and so on, there are various key factors that can influence its performance.
These technologies' security considerations impacting cloud computing are appropriate, for example, the network that links cloud computing to the outside world must be safe.
When mapping with physical structures, the virtualization principle must be carried out safely. Load balancing is the process of managing incoming request traffic, which can cause the server to become overburdened. Cloud computing security issues and solutions are affected by all these things.

POSSIBLE THREATS REGARDING CLOUD COMPUTING

Cloud computing has grown in importance to the point that it is now the centre of attention in the modern world. Along with its many advantages, cloud computing has a number of security problems that need immediate action in order to improve the infrastructure. The below are the key points to consider:

Outsourcing:

 As data is outsourced, the buyer can lose power. To prohibit cloud service providers (CSPs) from using data without their clients' permission, some kind of acceptable process is needed.

Multi-tenancy:

 A cloud is a repository of information that is accessed by other users. When offering a multi-tenant environment, data protection must be considered

Service Level Agreements:

 A clear contract between the consumer and provider is needed. The main goal of agreements is to build the trust.

Heterogeneity:

 Various cloud vendors have different data privacy mechanisms, which makes incorporation difficult.

• Server Downtime:

 The time it takes for a device to react to a client after a service interruption is known as downtime. Power backups should be installed and downtime should be held to a bare minimum. • Backup: In the event of a service outage, clients' data can be backed up. In SLAs, Cloud Sellers should state what the cure or remedies should be in the event of a catastrophe. There is a very small risk of a complete system collapse, such as a storm.

 • Data Redundancy:

 Data redundancy occurs where the same data is stored in two separate locations. Cloud storage may be described as providing clients with copies of the same data, program, or facilities. Data replication should be kept to a minimum by cloud sellers.

SOLUTIONS TO SECURITY CHALLENGES IN CLOUD COMPUTING 

Cloud computing security issues must be adequately handled. Adoption of the cloud system becomes more difficult if suitable solutions are not offered. Apart from adoption, data transmission and operation are becoming more laborious.

DATA ENCRYPTION 

Encryption is said to be a more secure method of data storage. Before sending data to the cloud, it should be secured. The data owner may grant access to specific members of his or her organization.
The file or data being sent to the cloud should be encrypted first, and then the cloud provider should encrypt it again before storing it on the cloud; this is known as multistage encryption. It has been discovered that combining multiple encryption algorithms results in stronger data encryption. The findings of the experiments show that RSA+IDEA has the best encryption efficiency in terms of data security.

LEGAL JURISDICTION

The most basic features of the cloud world complicate data privacy when it comes to understanding and analyzing the regulatory authority of cloud computing. Online networking, virtualization, dynamically distributed data, and global components are only a few examples. The majority of consumers are unaware of where their data is stored in the cloud.  For e.g., a client from India could be using a server in the United States, an application built in Japan, and his critical data stored in a data centre in Switzerland. As a result, the resource allotted to customers should be classified to ensure the data is kept separate.

DISTRIBUTED DENIAL OF SERVICE (DDOS) 

A distributed denial of service attack is one in which an attacker infects a server over the internet and turns it into a zombie. The corrupted computers are then used to target the survivor. When attacks/traffic from a large number of compromised computers is aimed at a single target, the victim's resources such as CPU, bandwidth, and memory are depleted, and the resource becomes unavailable. To deal with this, Deepali has created a fog layer that sits between the cloud server and the user. All requests to the server are routed via this fog sheet, reducing DDOS attacks.

 DIGITAL SIGNATURE 

In cloud storage, digital signatures are a powerful tool for securing records. Mr. Prashant Rewagad has suggested a solution that combines digital signatures with Diffie Hellman key exchange and the AES encryption algorithm to protect records. If the key is hacked during transmission, the Diffie Hellman key exchange facility is rendered worthless because it is useless without the user's private key, which is restricted to legitimate use. This three-way process introduced in this paper makes it more difficult to access encryption systems, thus shielding cloud-based data.


 CONCLUSION

This article provided an overview of cloud computing, including its numerous security implications and key factors that influence cloud security. Both the customer and the provider of cloud services should ensure that their cloud is completely secured. Cloud computing is gaining traction in every market, but it is beset by security and privacy concerns, which are preventing widespread acceptance. Solutions to these problems have been suggested which can be used for better performance of cloud service. In this article, cloud computing security issues and solutions were given to ensure maximum security for the users.
