Introduction

I. INTRODUCTION

With its ability to provide scalable, on-demand access to a wide range of computer resources via the internet, cloud technology has completely changed the face of modern computing [1]. Organizations may now manage their IT infrastructure more flexibly, cut expenses, and streamline operations thanks to this paradigm change. Cloud computing does, however, provide special security challenges in addition to its advantages [2]. To protect sensitive data and guarantee the integrity and availability of services, cloud systems' distributed nature, dependence on outside service providers, and shared responsibility model for security call for extensive security measures [3].

This review paper's objective is to offer a thorough examination of security assessment frameworks specifically designed for cloud computing. This study seeks to further cloud security practices by analyzing current app-roaches and suggesting improvements. The scope includes a thorough examination of existing security assessment frameworks, a critical evaluation of their advantages and dis-advantages, and the creation of a suggested framework that incorporates cutting-edge methods and best practices.

II. BACKGROUND

1. Since its conception, cloud computing has evolved significant-ly, moving from the primitive notions of utility computing to the complex models of infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and software-as-a-service (SaaS) that are used today [4]. Technological developments in virtualization, networking, and the growing need for adaptable and scalable computer resources have propel-led this progress. On-demand self-service, extensive network access, resource pooling, quick adapt-ability, and measured service are some of the main features of cloud computing [5]. These features promote efficiency and cost-effect-iveness by allowing custom-ers to scale services based on demand, pay only for the resources used, and access computing resources dynamically.

2. Security is still a top worry for businesses implementing cloud technologies, despite the many advantages that cloud computing offers [6]. Numerous issues, such as insider threats, data breaches, regulatory requirements, and the com-plexity of shared responsibility models, contribute to security challenges in cloud systems [7]. Strong security protocols and thorough risk assessment frameworks designed specific-ally for cloud settings are needed to meet these difficulties.

Numerous security evaluation frameworks have been created to tackle the unique security issues presented by cloud computing. These frameworks seek to offer instructions and methods for evaluating cloud-based systems' security posture, locating weaknesses, and putting in place suitable defenses [8]. Organi-zations can effectively minimize potential risks and improve their cloud security procedures by assessing the strengths and limits of these frameworks.

III. THEORETICAL FOUNDATIONS

In cloud environments, security evaluation is based on accepted principles to guarantee data and service availability, confidentiality, and integrity. The methodical process of detecting possible threats, evaluating vulnerabilities, and putting controls in place to lessen risks are all included in the concepts of security assessment [9]. In order to find potential flaws and vulnerabilities, this entails performing thorough assessments of the security posture of cloud-based systems, inc-luding infrastructure, apps, and data.

A good security assessment framework is made up of many parts that work together to make it easier to review and enhance security protocols in cloud computing settings. Typically, these elements include of risk identification, threat modelling, vulnerability assessment, evaluation of security measures, and remedial planning [10]. Organizations can sys-tematically evaluate the security risks associated with cloud adoption and apply suitable actions to prevent vul-nerabilities by integrating these com-ponents into a structured frame-work.

Because risk management offers an organized method for recognizing, evaluating, and controlling hazards, it is essential to guaranteeing the security of cloud systems. Risk management in the context of cloud security entails locating potential threats and vulnerabilities, estimating their impact and likelihood, and putting measures in place to transfer or lessen the risk [11]. By following this method, businesses may make well-informed decisions about adopting and utilizing cloud technology, ensuring that security protocols meet both legal and business requirements.

IV. REVIEW OF EXISTING SECURITY ASSESSMENT FRAMEWORKS

Numerous frameworks for security assessments have been created to handle the particular difficulties presented by cloud systems. This section examines three well-known frameworks, stressing their approach-es, advantages, and disadvantages.

A. Framework 1: Cloud Security Alliance (CSA) Security Guidance

The Security Guidance from the Cloud Security Alliance (CSA) is a thorough framework that offers recommend-ations and best practices for protecting cloud-based systems [12]. It addresses a number of cloud security topics, including as incident response, governance, risk manage-ment, and compliance. Stakeholders and industry experts have contributed to the framework, guaranteeing its adapt-ability and relevance to actual cloud implementations.

1. Strengths:

• Thorough examination of all cloud security-related topics.
• Awareness and adoption across the industry.
• Changes on a regular basis to take into account new dangers and technology.

2. Weaknesses:

• Lack of specific implementation guidance for different cloud service models.
• Limited focus on technical details and implementation specifics.

B. Framework 2: NIST Special Publication 800-53

A thorough list of security rules for federal information systems and org-anizations may be found in NIST Special Publication 800-53 [13]. Al-though it isn't designed with cloud settings in mind, it provides a strong basis for identifying security threats and putting in place the right safe-guards in cloud-based systems. Based on its goals, such as system and com-munications protection, incident res-ponse, and access control, the frame-work groups security measures into families.

1. Strengths:

• A comprehensive and organized list of security controls.
• Conformity to accepted security guidelines and rules.
• Adaptability to various cloud deployment methods in terms of controls.

2. Weaknesses:

• Limited guidance on cloud-specific threats and vulnerabilities.
• Requires customization to address the unique characteristics of cloud environments.

C. Framework 3: ISO/IEC 27001

An internationally accepted standard for information security management systems (ISMS) is ISO/IEC 27001 [14]. It offers a methodical approach to controlling security risks and putting controls in place to secure sensitive data, even if it is not tailored to cloud settings specifically. A wide number of security domains are covered by the standard, such as risk assessment, asset management, and incident management.

1. Strengths:

• Adoption and recognition on a global scale across industries.
• A focus on ongoing improve-ment via frequent audits and risk assessments.
• Integration with various standards for management systems, such ISO 9001.

2. Weaknesses:

• Inadequate instructions for putting security measures in place in cloud environments.
• Necessitates extensive custom-ization to handle dangers unique to the cloud and comply with regulations.

D. Comparative Analysis of Existing Frameworks

Upon conducting a comparative analysis, it can be observed that each of the three frameworks possesses strengths and shortcomings, rendering them appropriate for varying use cases and organizational requirements. Although the CSA Security Guidance covers cloud security best practices in great detail, NIST Special Publication 800-53 presents an organized list of security controls that can be used in a variety of IT environments. In contrast, ISO/IEC 27001 provides a widely accepted framework for handling information security threats; nevertheless, it needs to be customized to handle issues unique to cloud computing. In order to create efficient security assessment procedures in cloud environments, organizations should review these frameworks in accordance with their unique requirements.
