Cloud Security and Risk Management

Category: Computer Sciences Paper Type: Report Writing Reference: APA Words: 3200

            Cloud security is basically the protection of data that is available online from different cyber-attacks, deletion and leakage. There are different methods that are provided by the cloud security that include, penetration testing, firewalls, ionization, obfuscation, defusing public internet services and virtual private networks. Through applying these methods, cloud security services can be improved easily. The main aim of this article is to review cloud security, and its risk management in detail. These securities play an important role in protecting data, protecting customer privacy, and supporting regulatory compliance. There are some major threats to cloud security due to this that service is highly affected. These include data breaches, amount hijacking, insecure application program interference, data loss, service traffic hijacking shared technology, and also poor cloud storage providers. One of the most important threats to cloud security is the distributed denial of services. These kind of attacks are able to shut down the complete service by crushing the data completely. Through this, the user is unable to access this data from anywhere in the world.

        Many cloud security companies are working on proper risk management for the services. For development, every organization must have to extend their information system security risk management practice for implementing their cloud environment. Moreover, the organizations must have to understand cloud security in detail, so they are able to manage the risks in an effective way. It can be seen that risk management also involves the identification of technological assets, data and their links with the business. For this, all actions must be taken to minimize the cloud security risks in a proper way. The organizational owners must have work on minimizing the risk regarding cloud security for the future of technology.

Cloud security methods

    There are some methods of cloud security that are explained in the given section

Firewalls of Cloud Security and Risk Management

        This is basically a cloud-deployed, and software-based network devices are used for stopping and mitigating unwanted access to different private networks. This is one of the most important technologies that is designed for completing the modern business need, and also other online application environments. There are also some important benefits of cloud firewalls include better scalability, Availability, migration security, extensibility, identify protection, performance management, and secure access parity. There are two important types of firewall that include SaaS Firewalls and Next-generation firewalls (Management Association, 2019).

Penetration testing of Cloud Security and Risk Management

        This is one of the most important methods that is used for cloud security, and it is also called pen-testing. This is the method to test the computer system and its network in detail. This is basically a web application for finding security vulnerabilities for the attacker activity. This service can be automatic easily by a different software application and can be performed manually. Moreover, this process also gathers important data that is regarding target before testing and identifying important entry points. The main aim of this method is to test and identify the weakness that is present in the network.

        This method can be used to test the organizational security policy. This method also involves measuring the compliance of its security policy. Also, help the organization by guiding them about the different security disasters. This test also helps to highlight weaknesses that are present in the security policy of the company. There are also some penetration testing tools that will help to scan any kind of system easily. It will be easy to identify hardcoded values like passwords and usernames (Krishna, 2018).

Obfuscation of Cloud Security and Risk Management

        This is basically the practice to make something extremely difficult for understanding. This means that all things are written in machine language.  It can be seen that different programming codes are obfuscated for protecting the intellectual property and also prevent attacked from applying reverse engineering for hacking the system.

            This may include encrypting some part of the code or sorting meaningless labels to the code in the form of binary. This is one of the essential methods of cloud security. This can be implemented through the use of obfuscator tools that will help to convert automatically source code into an important program that is extremely hard to understand. The main purpose of obfuscating code is to protect the system or network from any kind of cyber-attacks. The programs that are written are in the form of C and C++ that will help to enhance difficulty for understanding (Tim Mather, 2009).

Tokenization of Cloud Security and Risk Management

            This is one of the essential methods of cloud security used by different banks. It is one of the methods used for breaking up the sequence in the form of strings into pieces like words, numbers, phrases, and keywords that are known as tokens. A token may be a single word or a complete sentence. After the process of ionization is applied to the sentence, some punctuation and characters are discarded, and then this token becomes the main input for the next text mining. This method is mainly used in computer science, and it plays an important role in the process of lexical analysis. Through the help of some steps, the tokens are separated easily

All of these tokens are separated by giving punctuation, white space, word, and number.

But the white space, punctuation marks are excluded that may depend upon the need.

After ionization, all of these characters are converted into a special one for the user, and it will help the user to protect its valuable data.

There some benefits of ionization that include

        If a security breach is activated by the user, so the cardholder’s information is protected. The reason is that the hacker was only able to access tokens that are completely useless. It will also help to reduce data environment for the user and help to save money and time for the user. Through the use of ionization, there will be end-to-end encryption. This means that the data can be encrypted and encrypted easily at no cost (Dotson, 2019).

Virtual private networks of Cloud Security and Risk Management

        This is also one of the methods used for cloud security. This will help to provide a safe, encrypted connection over a less protected network connection that is public internet. This technology only works through the use of shared public infrastructure through maintaining privacy by different protocols. Then, on the other hand, these protocols encrypt the data at the sending point, decry pt it at the receiving point. All data is sent through the help of the tunnel. This will not pass the data that is not fully encrypted. Through the help of this technology, the unwanted data is unable to send or receive.

        There are some important types of VPNs that include Remote access VPN; that can be used by the organization as the gateway server. Site-to-site VPN this is the server that is connected to the entire network through only one location. Mobile VPN helps the server to provide a safe gateway for the user through a data tunnel. This will also enable the safe server for the network. Hardware VPN, this is more beneficial than all software-based VPNs. This will also help to apply load balancing for handling a large amount of data from the user. VPN appliance is a software-based VPN that will help to enhance the security features of the entire network in a perfect way. VPN reconnect is one of the best features that is used in windows 7, and it will help to allow proper private network connection for internet services (Winkler, 2011).

Refrain from public internet connections of Cloud Security and Risk Management

    This is one of the simplest methods for cloud security. In this method, the user just has to avoid public internet services for uploading, sending, and receiving important data.

Risk Management for Cloud Computing

        Cloud computing is one of the finest computing strategies that have the potential to provide flexible, agile and cost-effective information services. Under the paradigm of cloud computing, the cloud service provider (CSP) given up the direct control on many security aspects and the privacy by some organisations. Many organisations are using the cloud services at the same time that are still accountable for availability, confidentiality and integrity of the related information and information about the system hosting the cloud service provider (CSP).

        As a result, the information system security practice of risk management must be extended by organisations to add up the cloud environment. The shareable nature of using and operating the cloud environment changes that will be responsible for the construction or implementation, functionality and the maintenance of the security controls. Therefore, the organization who are using cloud computing must need to take understandings about cloud security to address all the risks effectively. The organisations or corporation can address the risks effectively by understandings about cloud security (Carlin & Curran, 2013).

        To establish the cloud-based services, the government designed and constructed the integrated risk management approach for the adoption of cloud computing. So the proposed approach, which is designed and developed at the governmental level, could be applied to all the services on cloud-based. This approach could be applied independently to all cloud-based services and could apply to the deployment models.

        The cloud service providers (CSP), due to the economies of scale, have the potential to offer state of the art in the cloud ecosystem and secure than a customer’s environment who are controlling own systems. In simple words, it has the potential to give benefits to many organisations effectively. Moreover, there is a need to make visible the customers data of the business into the cloud provider’s service, to build up the essential trust for the cloud-based solution in the sense of adoption benefits to store the customer’s data in the cloud (Osmanoglu, 2013).

        The stored data in the cloud is so much sense and commonly considered against the proposed incurred security and the risks in privacy. In simple, the cloud-based solution benefits should depend on the cloud model, the kind of cloud service, type of complexity level, type of involved data, several services type and also depends on the different types of the requirements. The information systems which based on the cloud are exposed threats, and it can have negative effects on the operations of organisations such as the functions, missions, vision, or reputation (Loske, 2015).

        The malicious entities in the cloud could be very harmful, which can damage the information or the incurred data of the customers. However, it can damage the stored information into the cloud database of customers of the organisation and availability of the confidential information by those systems. There are several kinds of risks that should be addressed by the organisations for the solution. However, risk management considered as a holistic activity, which is full-fledged integrated with every aspect of the organisation.

        The selection of the appropriate management satisfies the requirements of Information security from the standard uncatalogued of controls and security. Organisations should do quantify their risks which are acceptable to prevent or minimize the threats, negative actions, attacks or compromises. In other words, the organisations that are using cloud services, they may face many threats and negative actions. So they need to count all the risks which can damage the service or confidential information to prevent or mitigate the threats, disruptions in the service, cyber-attacks and the adverse actions (Ackermann, 2012).

        For the management of the information security risk effectively at the ecosystem level, you need to establish the following high-level elements.

        The risk management responsibilities assigned to the cloud actors would be involved in the cloud ecosystem’s orchestration. Every cloud actors should assign the responsibilities to the respected representatives, managers, leaders or executives internally.

        Under the instructions of service level agreement (SLA), the establishment cloud ecosystem widely tolerance the risks as well as communication of such risk tolerance. It needs to add up the information on the decision-making activities which can be impactful on the risk tolerance.

        Near the real-time recognition, screening, monitoring and understanding of information security system by every cloud actor from the risk operation is.

        The cloud actors count up the threats, malicious actions or attacks, decision making in the risk management process, and the solutions during the real-time information sharing.

The risk management framework

        The risk management framework integrates information security and risk management activities for the provision of a disciplined and structured method in the system development life cycle (SDLC). Researchers introduce a risk management framework (RMF) that provides the risk executive with the feedback during the monitoring and through the decision of authorization such as spreading the updated and upgraded information about risk to the owners of information system.

                           

        The picture highlights information all the steps of the risk management framework that enlighten on its functionality about the self-managed subsystems or system. The figure indicated its three levels having six elements or steps. All of the mentioned levels and stages explained. Risk management contains two steps, such as categorization and selection. Risk treatment contains three steps, including implementation, assessment and authorization. But the risk control contains only one stop, which is denoted by monitor. All steps of the risk management framework explained mentioned below.

Risk Assessment of Cloud Security

I        n this level, analysis of the cloud environment will perform for the identification of the effective and potential vulnerabilities and short-comings. This level has two steps for gathering information and then analysis. The steps are as follows categorization and selection.

Step 1: Categorization

        The information system concerns the processed, transmitted, and the stored information by the proposed system, which based on the system impact analysis. In this step, the proposed information, data about risks are categorized by following some rules that belong to the operations identification, its performance, requirements of privacy and security.

Step 2: Selection

        This step is based on the security that is categorized and concerns with the initial set of security of controls for the information systems, which refers to the security controls of the baseline. The proposed baseline security controls set on the assessment of the organisation for risk and its current conditions of the environmental operations. The strategy will be made up for monitoring the security controls for evaluation of the effectiveness of the security control. In the end, you have to write all the controls and outcome into a word document along with the remarks that show where the issues occurred and how they could be refined in the security plan. The last thing is to take a look again for the review and approve all security plan (Sabri Boubaker, 2016).

Risk Treatment of Cloud Security

        Risk treatment is concerned about the treatment in the risk management framework where we can check the design mitigation plans and the related policies. The proposed level has three following steps, such as implementation, assessment, and the third one is authorization.

Step 3: Implementation

        The implementation step indicates the implementation of the security controls as well as gives a brief description of how the controls employed within its environmental operation and the information system.

Step 4: Assessment

        it is all about to assess the security controls by using the proposed assessment procedures which documented in the assessment planning. It is a very useful step in the risk management framework or in the risk management process which identifies that if the security controls are being implemented correctly without any error or fault as well as it is fully functional or effective in producing the required outputs.

Step 5: Authorization

        This step is all about the information system operation, which based on the identified risks in the results from the information system‘s operations. Just identify the real outcome and decide on risks that they are acceptable or not. If it is acceptable, then you should go further. The all organisational operations such as the image, reputation, organisational mission or functions, organisational assets and the other requirements also performed in the assessment of risks step.

Risk Control of Cloud Security and Risk Management

        this step for the security controls of the information security systems is one of the most important steps for risk control. In the risk management framework on the bases of assessing the security control effectiveness, making changes in the documentation of the proposed system or the environment of the operations, effective analysis about the proposed changes as well as the stated or highlighted security of the system to the designated of the organizational officials and concerns with the other required things.

Conclusion on Cloud Security and Risk Management

        Summing up all the discussion from above, it is concluded that cloud security plays an important role in providing internet services. Through applying these methods, cloud security services can be improved easily. The main aim of this article is to review cloud security, and its risk management in detail. These include data breaches, amount hijacking, insecure application program interference, data loss, service traffic hijacking shared technology, and also poor cloud storage providers. This service can be automatic easily by the different software application and can be performed manually. This method can be used to test the organizational security policy. The risk management framework integrates information security and risk management activities for the provision of a disciplined and structured method in the system development life cycle (SDLC).This level has two steps for gathering information, and then analysis Risk treatment is concerned about the treatment in the risk management framework where we can check the design mitigation plans and the related policies.
