security management standards in cloud computing

This process includes collection, handling, storing and deletion of private data. 8 NIST defines a hypervisor as the virtualization component that manages the guest operating systems (OSs) on a host and controls the flow of instructions between the guest OSs and the physical hardware. The distributed nature of cloud service allows remote access of the service. Software dependencies: When a CSP's system consists of components provided by various CSNs, it won't be able to make changes immediately upon detection of a vulnerability because this change may affect multiple components and as the components are from different CSNs some of them might not be compatible to this changes. The laws, regulations and standards have to be met. Here, private information is personally identifiable information, credit card details, religion, sexual orientation, health records etc. Figure 1: ITIL life cycle in an organization. 1 The FFIEC comprises the principals of: the Board of Governors of the Federal Reserve System, Bureau of Consumer Financial Protection, Federal Deposit Insurance Corporation, National Credit Union Administration, Office of the Comptroller of the Currency, and State Liaison Committee. It is therefore necessary for the CSPs to ensure that data privacy is maintained. The standard suggests the following cloud computing security capabilities to mitigate the security threats discussed in section 2 and the security challenges discussed above [X1601]. This may allow an attacker to tamper with the cloud [X1601]. CSCs assume that the service providers provide the "principle of least privilege" to their data. 11 In the National Security Agency’s “Mitigating Cloud Vulnerabilities, (opens new window)” the report notes that misconfigurations of cloud resources include policy mistakes, a misunderstanding of responsibility and inappropriate security controls. The period for which the data should exist in the cloud is decided by CSC. The ITU standard presents a sketch of issues pertaining to cloud computing and proposes a framework for cloud security. Cloud computing environments are enabled by virtualization4 technologies, which allow cloud service providers to segregate and isolate multiple clients on a common set of physical or virtual hardware. This describes the roles and responsibilities of those involved, how they interact and communicate, and general rules and policies. It exists on the premises of the cloud provider.”. 16 NIST Special Publication 800-204 Security Strategies for Microservices-based Application Systems (opens new window) provides additional technical details for financial institutions considering the use of microservices. Failure to implement an effective risk management process for cloud computing commensurate with the level of risk and complexity of the financial institution’s operations residing in a cloud computing environment may be an unsafe or unsound practice and result in potential consumer harm by placing customer-sensitive information at risk. Protect data, apps and infrastructure quickly with built-in security services in Azure that include unparalleled security intelligence to help identify rapidly evolving threats early – so you can respond quickly. In this section we discussed what regulations and reforms are necessary on both the CSC end and CSP end to maintain confidentiality of information being put on the cloud. Identity management is important in authentication, authorization and access control. How is the data stored within the cloud? Security challenges for cloud service providers: This clause describes the challenges that affect the CSPs. The five standards described below discuss in detail the breadth of issues they cover with regard to cloud security. The TC identifies gaps in existing identity management standards and investigates the need for profiles to achieve interoperability within current standards. Identity Management : An identity management system controls access to data and information. Cloud computing environments are enabled by virtualization. This feature makes the CSPs vulnerable to many security issues. For example, a government might want to keep the data of its citizens within the country and for an exact duration. Cloud systems could integrate the CSC's identity management system with what they have. Evolutionary risks: Evolutionary risks arise when some system choices' implementation is delegated to the execution phase of the system rather than the design phase. This makes it a risk for the CSC to trust the CSP with its data and keeps the CSC at a high security threat in using the cloud services. All services provided by the cloud must be available at all times. The standard divides the roles of an individual or an organization into following three categories [X1601]: Cloud security challenges are defined as those faced due to the operating environment and nature of the cloud service. There is no way of ensuring that the CSP deletes all copies of CSC data when the CSC intends to do so. It aims to provide further guidance in the information security domain of cloud computing. The features that make cloud-computing stand apart from other non-cloud techniques also make it susceptible to many attacks and it has to deal with many security issues. Data isolation may be provided physical or virtually. Visibility is very important for CSCs to ensure compliance. OMB also helped develop the If a CSP does not ensures the destruction of data beyond the retention period, it may result in exposure of private and confidential data. Hence, the security practices must be continually revised to keep it updated and efficient. VMware Cloud Services Security Overview Physical and management layer security Physical security In a cloud environment, solid compute, storage and network security is only as effective as the security of the physical environment used to house the infrastructure. For instance, a cloud service provided by a CSP will be shared by many CSCs. The cloud security guidelines are intended to support Victorian Government organisations in making informed, risk-based decisions about the use of cloud services. The primary function of a cloud however, is to provide service. In this section we consider the threats that are faced by a CSC. Cloud security consists of a set of policies, controls, procedures and technologies that work together to protect cloud-based systems, data and infrastructure. In the current scenario we tend to place a lot of data in the cloud, but what do we really know about its security? It is a set of best practices and guidelines that define an integrated, process-based approach for managing information technology services. In parallel it also provides the ability to encrypt package to ensure its safe delivery. Integrity : Integrity means that no data should be modified when it is transferred from source to destination. It is important that everything we put on the cloud does not fall into malicious hands. Additionally the standard will provide further security advice for both: clients and service providers. Thus, for implementing ITIL a detailed analysis of existing processes along with gaps in relation to the ITIL framework and level of process integration would be needed. Due to this sharing of storage resources if the data of a CSC is not sufficiently protected using proper cryptographic management then it may lead to exposure of a CSC's data to other CSCs who might not be authorized to access this data [X1601]. Enterprise can also press for encrypting its data and allow only authorized people to access the data. Interface security: This capability refers to securing the interfaces that are responsible for providing cloud services to various CSCs. Bad migration and integration: For migrating a system to a CSP, a large amount of data has to be moved to the cloud. Additional information on general third-party risk management and outsourcing practices is available in the FFIEC Information Technology Examination Handbook’s “Outsourcing Technology Services” booklet and other documents published by FFIEC members. Carelessness of one such employee can lead to compromising of the CSP's administrative credentials and may allow an attacker to gain complete control of the cloud [X1601]. Confidentiality : Confidentiality is the second most important aspect of security. We further lay emphasis on ISO/IEC 27017, a standard that is currently being drafted that brings out other finer aspects of cloud security. The standards above describe in detail the considerations to make cloud computing safer for the end user and provide an experience where there is no loss of data or identity. This statement does not contain new regulatory expectations; rather, this statement highlights examples of risk management practices for a financial institution’s safe and sound use of cloud computing services and safeguards to protect customers’ sensitive information from risks that pose potential consumer harm. Shared environment: The idea of cloud services is sharing of resources on a very large scale. "Cloud Service provider: The cloud service provider should define and document the demarcation of responsibilities of cloud service customer, cloud service supplier and its suppliers" [ISO27001]. 15 NIST Glossary (opens new window) defines a microservice as a set of containers that work together to compose an application. Scoping Considerations:Organizations looking to store, process, or transmit payment card data in a cloud environment should clearly understand the impact that the cloud will have on their PCI DSS scope [PCI13]. Implement a layered, defence-in-depth strategy across identity, data, hosts and networks. According to the memorandum, the Federal Government ’s adoption and use of information systems operated by cloud service providers depends on security, interoperability, portability, reliability, and resiliency. Cloud computing has been one of the most important innovations in recent years providing cheap, virtual services that a few years ago demanded expensive, local hardware. OVF 2.0 was released in January 2013 [OVF2]. 8, issue 4, ISSN 1336-1716, pp. The client holds the responsibility of ensuring their cardholder data is secure under PCI DSS requirements. Risk management expectations for the management of relationships involving third parties (such as third-party cloud computing services) are outlined in FFIEC members’ respective guidance and the Information Security Standards. Management’s failure to understand the division of responsibilities for assessing and implementing appropriate controls over operations may result in increased risk of operational failures or security breaches. OVF thus provides customers: vendor and platform independence as it facilitates mobility of virtual machines [OVF2]. SecaaS solutions may not be directly involved in storing, processing, or transmitting[PCI13]. Application Security : With PaaS, CSCs can design their own applications on the platform in the cloud. [Hocenski10, Shahed09, Wiki]. Due diligence and sound risk management practices over cloud service provider relationships help management verify that effective security, operations, and resiliency controls are in place and consistent with the financial institution’s internal standards. It is also required for third-party audits and procedures like Electronic Discovery (eDiscovery). We then talked about Open Virtualization Format 2.0, which provides guidelines for distributing a software over the cloud. It is possible that this software might be tampered with or might be affected while the software is running in the CSP and is not in CSC's control, resulting in CSC's loss over its software. The clouds, as of today, are by definition "black box". The more security controls the CSP is responsible for, the greater the scope of the CDE will potentially be, thereby increasing the complexity involved in defining and maintaining CDE boundaries. Loss of trust: Because of the abstraction of the security implementation details between a CSC and a CSP, it is difficult for a CSC to get details of the security mechanisms that the CSP has implemented to keep the cloud data secure. SaaS makes the CSP take maximum responsibility of security management. It gives business executives the knowledge necessary to make informed, educated decisions regarding cloud initiatives. The standard advises both cloud service customers and cloud service providers, with the primary guidance laid out side-by-side in each section. Ongoing oversight and monitoring of a financial institution’s cloud service providers are important to gain assurance that cloud computing services are being managed consistent with contractual requirements, and in a safe and sound manner. This standard is yet to be launched in the market. They provide a comprehensive structure on how security in the cloud is maintained with respect to both the user and the service provider. "For example, in a private-cloud deployment, an organization could either implement adequate segmentation to isolate in-scope systems from other systems and services, or they could consider their private cloud to be wholly in scope for PCI DSS. Use of cloud computing services may introduce security challenges and the University must manage how the cloud provider secures and maintains the computing environment and University information assets. The IEEE Standards Association (IEEE-SA) is a leading consensus building organization that nurtures, develops and advances global technologies, through IEEE. Even after putting all the security measures in place, a breach of privacy is still possible. ISO 27017 is the cloud security standard being developed with expanded control sets for cloud computing. This might result in the violation of a CSC's confidentiality and integrity. From the perspective of a CSP, the CSCs may be able to sue them if their privacy rights are violated. The term "Cloud computing" came into existence to define the change that occurs when applications and services are moved into the Internet "cloud". Implement a dedicated physical infrastructure that is used only for the in-scope cloud environment. Especially in a SaaS or PaaS model, a majority of the system level logging and auditing is under the control of the CSP. The ITU-T X.1601 standard gives a detailed insight into different services provided by the cloud, the main threats that a cloud environment faces, the challenges in providing or using cloud services, the security capabilities that help in mitigating these threats and challenges. Regardless of the environment or service model used, the financial institution retains overall responsibility for the safety and soundness of cloud services and the protection of sensitive customer information.9. One important aspect of ITIL, pertaining to cloud computing, is continuously changing organizations and information systems [Fry]. ISO 27018 is the cloud privacy standard being … Loss of privacy: CSC's privacy may be violated due to leakage of private information while the CSP is processing CSC's private data or using the private information for a purpose that the CSP and CSC haven't agreed upon. Cloud security is a shared responsibility between the CSP and its clients. Based on the services that a CSP provides and the cloud environment, a CSP may face the following threats. Information Security Standards. Even if the workload has been moved to the cloud, the onus of compliance and protection has to be borne by the CSCs. NIST generally defines three cloud service models.7 For each service model, there are typically differing shared responsibilities between the financial institution and the cloud service provider for implementing and managing controls. This leakage may violate the CSC's copyrights and may result in the disclosure of CSC's private data. Availability : Availability is an important part of any system. Ensuring the integrity of the data (transfer, storage, and retrieval) really means that just the data is changed only in response to authorized transactions. Are there multiple copies of the data that is stored? The next standard PCI DSS focuses on authenticating the CSP and CSC for secure data handling on both sides. Most organizations have security, privacy and compliance policies and procedures to protect their IP and assets. In the following section, we enlist a few concerns related to security governance, regulation and compliance (GRC). security standards are numerous: • Standards promote interoperability, eliminating vendor lock-in and making it simpler to transition from one cloud service provider to another. Physical security: This capability requires that access to the CSP premise should be granted only to authorized personnel and only to those locations that are necessary for the job function. In this section we also touch upon a new standard that will be published in 2015 for general use. PCI's main objective is to provide security guidelines for credit card usage and address CSP's and CSC's. Data isolation amongst users is important. Inside threat : A CSP needs to be careful in providing administrative access to its employees. However, if there are no multiple copies of data, then an attacker that has hijacked a session or gained privileged access, could request for the data to be destroyed and all data will be lost [Hocenski10, Wiki]. Security as a Service, or SecaaS, forms an integral part of the security of the cloud. Privacy has another threat - the insider threat. It further talks about a standard yet to be released and how it would impact once it is in the market. The service option that the client has selected to engage the CSP (IaaS, PaaS or SaaS). Cloud Computing is governed under the system-wide policy BFB-IS-3: Electronic Information Security. This may enable an attacker to gain unauthorized access to cloud if an attacker can manage to pose as a valid CSC. Organizations tend to have their own identity management system. Different models of cloud computing leads to variation in the amount of responsibility taken by the CSP and by the CSC. If the remote connection is not secure then it may leave an open gate for an attacker to sniff for the CSC's credentials [X1601]. When data privacy issues are governed by foreign laws, violation of a law by CSP or CSC may cause major risk due to exposure of private data. The use of non-standard functions and cloud framework makes the CSP non-inter-operable with other CSPs and also leaves CSC open to security attacks. It is one important aspect that must be of absolute assurance to the CSC. Cloud computing environments are enabled by virtualization 4 technologies, which allow cloud service providers to segregate and isolate multiple clients on a … Apart from these, threats can also arise due to indirect denial of service, attacks such as cross-VM side-channel attack and malware infection [Shacham09]. information security management standards (like ISO270001) to fit better the situation of cloud computing service providers. This raises confidentiality concerns as the regulating Privacy Laws are different in different regions and some of these might me unacceptable or harmful to CSCs. A cross-VM side-channel attack could compromise the confidentiality of a system. It is aimed at supplementing the guidance in ISO/IEC 27002 and various other ISO27k standards including ISO/IEC 27018 on the privacy aspects of cloud computing, ISO/IEC 27031 on business continuity, and ISO/IEC 27036-4 on relationship management, as well as all the other ISO27k standards [ISO27017]. Figure 1 shows the ITIL life cycle in an IT organization as described above. Distributed Management Task Force (DMTF). Most business organizations are currently using cloud to handle multitudes of business operations. These services fall into the following categories: An important aspect of moving everything into the cloud is to keep everything safe and secure. A risk management process must be used to balance the benefits of cloud computing with the security risks associated with the organisation handing over control to a vendor. Examples of these include NIST, the Center for Internet Security’s Critical Security Controls, and the Cloud Security Alliance. The principle of least privilege states that only the minimum access necessary to perform an operation should be granted, and that access should be granted only for the minimum amount of time necessary [Hocenski10, Wiki]. 20 Cloud access security brokers are generally products or services that monitor activity between cloud service users and cloud applications and can typically be used to enforce security policies, alert for anomalous activity or monitor performance. Inconsistency and conflict of protection mechanisms: An attacker might be able to exploit the decentralized architecture of the cloud because of the discordant security systems among various distributed systems. These models and the typical responsibilities include: These examples describe typical shared responsibilities for the different service models; however, the specific services and responsibilities will be unique to each service deployment and implementation. 5 The NIST Glossary (opens new window) defines private cloud computing as “The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). DoD Cloud Computing SRG v1r3 DISA Risk Management, Cybersecurity Standards 6 March, 2017 Developed by DISA for DoD UNCLASSIFIED iv 5.1.2 DoD FedRAMP+ Security Controls/Enhancements..... 44 5.1.3 Parameter Values for Security Controls and Enhancements ..... 47 In addition to this, organizations should establish a formal governance framework that outlines chains of responsibility, authority and communication. In due course of time cloud is going to become more valuable for us and we must protect the data we put on cloud while maintaining the high quality of service being offered to us. Standards in Cloud Computing IEEE Standards Association. Though the responsibility for managing security is shared between client and provider the client still has an important role to play. It will do that by offering advice for both side-by-side in each section. Compatibility : Storage services provided by one vendor may not be compatible with those provided by another vendor. The division of responsibilities between the client and the CSP for managing PCI DSS controls is influenced by multiple factors, which are [PCI13]: The client must have a clear understanding of the scope of responsibility that the CSP is accepting for each PCI DSS requirement. Section 3 of our paper discusses in detail the various Governance measures required to stem these issues. Information. Additionally, traditional security controls, such as firewalls and intrusion detection systems, may not be effective because containers may obscure activities; therefore, container-specific security solutions should be implemented. Across the cloud OVF plays a major role in providing cross-platform portability. SecaaS plays the role in such a manner that it offers a PCI DSS control to the client's environment. Is it encrypted so that even the administrator can not see it without the decryption key? There are also many industry-recognized standards and resources that can assist financial institutions with managing cloud computing services. Privacy ensures that data, personal information and identity of a CSC must not be revealed to unauthorized users. The Statement categorizes risk management practices into the following sections: Governance; Cloud Security Management More often than not, the resources span multiple jurisdictions, which make the issue of compliance complicated. Who is responsible for ensuring this: the CSP or the CSC? The ambiguity as to whether a CSP or a CSC should adhere to a given responsibility varies with change in jurisdictions and can be vague at international level. Management should refer to the appropriate FFIEC member guidance referenced in the “Additional Resources” section of this statement for information regarding supervisory perspectives on effective information technology (IT) risk management practices. See 12 CFR 30, appendix B (OCC); 12 CFR part 208, appendix D-2, and 12 CFR part 225, appendix F (FRB); 12 CFR 364, appendix B (FDIC); and 12 CFR 748, appendix A (NCUA) (collectively referenced in this statement as the “Information Security Standards”). 2 NIST SP 800-145, The NIST Definition of Cloud Computing: Recommendations of the National Institute of Standards and Technology (opens new window), defines cloud computing as a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or third-party service provider interaction. The challenges arise in addressing issues such as data ownership and access control. "For example, if payment card data is stored, processed or transmitted in a cloud environment, PCI DSS will apply to that environment, and will typically involve validation of both the CSP's infrastructure and the client's usage of that environment". Cloud Computing: Implementation, Management, and Security provides an understanding of what cloud computing really means, explores how disruptive it may become in the future, and examines its advantages and disadvantages. Securing the host from containers and vice versa. It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.”, 6 The NIST Glossary (opens new window) defines public cloud computing as “The cloud infrastructure is provisioned for open use by the general public. Above we have described the most important threats and issues that arise in the field of cloud computing and how they may cause problems to a CSP or a CSC. The OASIS IDCloud TC works to address the serious security challenges posed by identity management in cloud computing. February 2013 2.0 Initial publication of PCI DSS v2.0 Cloud Computing Guidelines, produced by 2013 Cloud SIG. It aims to provide an advancement to ISO/IEC 27002 in terms of adding value to its practices of control implementation. The standard discusses the security challenges based on the nature of the role that an individual or an organization plays in the cloud computing paradigm. Portability provides a CSC the freedom of migrating from one CSP to another CSP and reversibility refers to the ability of a CSC to remove its data from cloud back to its non-cloud storage. IaaS makes the subscriber solely responsible for security of almost all the entities except physical security of the hardware, the infrastructure itself. Financial institutions use private cloud computing environments,5  public cloud computing environments,6 or a hybrid of the two. Financial institution management should engage in effective risk management for the safe and sound use of cloud computing services. Management should not assume that effective security and resilience controls exist simply because the technology systems are operating in a cloud computing environment. April Updated PCI SSC Guidelines for Secure Cloud Computing, produced 2018 3.0 by 2017 Cloud SIG. Loss of governance: When the CSC uses cloud services, it has to move its data onto the cloud and has to provide certain privileges to the CSP for handling the data in the cloud. The exact location of the CSC's data in the cloud is not known to the CSC. 12 For example, refer to NIST’s Framework for Improving Critical Infrastructure Cybersecurity (opens new window), February 12, 2014. NIST aims to foster cloud computing practices that support interoperability, portability, and security requirements that are appropriate and achievable for important usage scenarios. Access insecurity : Due to the distributed and shared nature of a cloud, accessing cloud services may also pose threats to the CSCs. In this paper we delve into the details of security aspects of cloud computing and the paper is divided into the following sections. 285-292, 2010. 3. An CSP insider could easily access personal data of CSCs, if the encryption keys were available to the CSP, the stored data was not encrypted or if the data was stored in multiple locations. Advantages of using OVF:OVF 2.0 brings a lot on the table for the packaging of virtual machines, making the standard applicable to a broader range of cloud use cases that are emerging as the industry enters the cloud era. Security breaches involving cloud computing services highlight the importance of sound security controls and management’s understanding of the shared responsibilities between cloud service providers and their financial institution clients. The challenges are classified based on whether the participant is CSP or CSC [X1601]. 4 The NIST Glossary (opens new window) defines virtualization as the simulation of the software and/or hardware upon which other software runs. Ambiguity in responsibility: A CSC uses services based on different service categories as well as different deployment models. Cloud computing is a model, as defined3 by the National Institute of Standards and Technology (NIST), for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be As we have already discussed major security threats for cloud computing in section 2, in this section we will discuss the cloud security challenges and the security capabilities that this standard deals with and those help in mitigating the relevant threats [X1601]. Data isolation, protection and privacy protection: Data isolation: It refers to preventing access and visibility of one party's data to another party in the shared environment. These cloud computing security measures are configured to protect data, support regulatory compliance and protect customers' privacy as well as setting authentication rules for individual users and devices. 3.
