  2. 2. Limitations of Security Standards against Public Clouds Yury Chemerkin Russian State University for the Humanities (RSUH) Moscow, Russia yury.chemerkin@gmail.com Abstract – Since a web-technology has arisen and clouds has come, every application wants to be online and operates with sensitive data that cannot but attract anyone to get an access this data. It means an urgent need in security. Examining the clouds leads us to different visions of security controls and metrics per each cloud vendor while industrial organizations try to help to the vendors and their customers with an appropriate security level. They offer a transparency of security controls that belong to different vendors against the best security practices. Keywords: cloud security, amazon web services, aws, azure, compliance, csa recommendations, nist sp 800-53 rev.3, nist, csa I. INTRODUCTION A cloud goal is delivering various computing resources like computing, storage, databases as paid services over the web. It is generally known, cloud vendors provides it without infrastructure and location details that is partially wrong or depends on certain vendors as well as cloud may bring quite unique concerns on security field. As opposed to a private cloud, a public cloud hypervisor does not provide APIs unfortunately to manage any process and flows that totally has nothing new from managing a blackbox several decades ago. It is just as trust like downloading and buying third-party solutions while cloud solutions are third party too. To build a security and privacy, cloud vendors provide their customers with security controls on areas like data protection, identity management, application and system/network security and availability. However, the customers must meet a transparency of security controls in alignment with industrial standards, while vendors must enable them to comply with it. Standards like the documents of NIST, ISO, PCI DSS, etc. provide a measure on information security from the perspective of security at least because there are various ways to get the same security level. However, such standards look like more detailed and go deeply on security and privacy than guidance, best practices and metrics promoted by CSA. They try to bring a transparency on clouds but results are far away from it that makes the customers actions uncertain. This research examines MS Azure and AWS clouds in alignment modern security standards and goes to explain possible issues to obtain “trustable security controls” in according to a compliance and present a working out the details of recommendations among several standards. In addition, it addresses a deeply analysis between different cloud vendors on security. The paper extends the results of previous [2-4] on security, compliance and transparency of AWS controls. II. RELATED WORK MS Azure has become one more popular cloud platform along with Amazon Web Services (AWS) as an open cloud platform to operate with web sites, applications, mobile services, VMs, BigData, MediaStream and more. These clouds are both so popular that both are a background for iCloud [5]. An examination of AWS security controls with their transparency in alignment security guidance and ability to pass it easy were given in paper [4], [3]. A quick analysis of AWS and Azure was given in paper [2]. As Azure has purposed of data spreading, it shifts a significant part of security from typical layer (network, OS, etc.) to an application layer on standards examination as opposed to AWS [12]. That is key thing why a cloud security might have unique concerns under the mask of a non-typical interaction, but certainly known within a scope of a penstest and audit of applications. In general, it replaces a user/password plus MFA access to an x509 access keeping basic security rules. The standards with best practices together are known provides us with a least security that sometimes dumped with descriptive generalizations and properties, because simplification and reducing are not the same things. For example, a paper is about top nine cloud threats [1] as opposed to seven previous covers quite mixed facts related to private clouds than public. These examples in the link section are  “1.0. Top Threat: Data Breaches // Cross-VM Side Channels and Their Use to Extract private Keys”, “7.0. Top Threat: Abuse of Cloud Services // CrossVM Side Channels and Their Use to Extract private Keys”  “4.0. Top Threat: Insecurity Interfaces and APIs” // both examples The first case highlights how the public clouds e.g. AWS EC2 are vulnerable but totally focused on a private cloud case (VMware and XEN), while there is no a known way to apply it to AWS [9]. Instead, the work [7] explains how to compromise EC2 & S3 control interfaces with different modern techniques, but Amazon advises a native configuration against it [8]. The second case presents issues raised by a SSO access without relation to the public clouds (except Dropbox, SkyDrive) and addressed to insecurity of APIs. A paper is about issues of SSL validation [10] is a similar example, successfully solved by AWS. Dumping all generalized facts and recommendations into the basket is not good idea and may leads to the statements like “cloud vendors do not provide with full detailed to let us trust and ensure us in privacy”. First of all, the cloud vendors have their infrastructure built and Copyright © i-Society 2013 Technical Co-Sponsored by IEEE Toronto Section 58
  3. 3. configured in according to the standards like ISO, PCI DSS, CoBIT that validated by independent auditors and experts every time. Second, providing such results under a NDA only (shifting details to private reports) should be mainly reasonable especially in technical cases. By way of example, an examination of AWS services against CSA requirements gives a vague answer about a real transparency bringing by CSA recommendations, because almost a third part of all responses covers such private reports [3-4]. However, not all solutions may provide the cloud customers with a proper protection. A forensics sanitization like an ERASERS proposed in [6] is a good concern for the clouds VM storages such as AWS EC2 only, not for a data storage provide by such services like AWS S3, Dropbox and similar. In this case, it is impossible to use wiping per each file; instead, it is allowed to data volumes upload as a single unit or rely on a cloud implementation according to DoD techniques. Such documents have a claim to be up-to-date with expertlevel understanding of significant threats and vulnerabilities to let to build an appropriate strategy to redress them. Everything taken together calls for an additional analysis on cloud TABLE I. Description compliance and transparency area to reduce misunderstanding of several standards’ requirements applied to clouds. III. EXAMINATION CSA REQ. ON AZURE AND AWS CSA documents are known try to level up a state of knowledge on cloud security; it gained to improve a visibility of cloud controls and features to help the customers easy meet with certain requirements, include local law regulations. The Table 1 addresses to the differences between AWS and Azure according to meet the CSA requirements as well as differences between the requirements of CAIQ [14] and CMM [13] against Azure in the docket; Microsoft has already filled the CAI Questionnaire [15], but it is CMM in fact. An examination takes a place to meet it from a technical (features) point of view in the first place. Each control ID is kept with a control group description but without ID control explanation; in addition, it is grouped by similar metrics. If there is any difference between CAIQ ID and CMM ID, there will often be a difference between AWS and Azure except cases such as swapping IDs or repeating it. DIFF. BETWEEN AWS AND AZURE VS.

ON AZURE AND AWS A paper [11] provides a brief examination several clouds (AWS EC2, Azure, GAE) against NIST through the mapping security and privacy attributes to NIST guidelines but not goes deeply. However, NIST documents SP800-144 [16], SP800146 [17] provide with general considerations how to improve a cloud security that does not bring a transparency of cloud controls and are still in progress to be similar to NIST SP80053 by reducing non-cloud statements that is partially helps the customers because of a limitedness and focusing only on cloud. In other words, even it seems as a non-applicable requirement, such excluding may remove some objects like mobile endpoints from an infrastructure and cripple a perceptual unity. That is why the Table 2 contains an examination cloud controls in alignment NIST SP800-53 Rev.3 (rev.4 has not released yet) [18] and covers a technical class only; withdrawn controls are missed. Several conditions used in the Table 2: Abbr. "w/o" means basic requirements. Abbr. "w" – with control enhancements. Abbr. "CE" means control enhancements where "None" means there are no enhancements. Abbr. "N" means there is no ability to meet this requirement. Abbr. "Y" means basic TABLE II. ID services of clock No Besides the AD (Active Directory) AWS IAM solution are alignment with both CAIQ, CMM requirements while Azure addresses to the AD to perform these actions AWS refers to the ISO 27001/27002, CoBIT, PCI DSS while Azure refers to the ISO 27001 AWS provides more details how-to documents to having a compliance No Besides vendor features, AWS provides quite similar mechanism in alignment CAIQ & CMM, while Azure points to features built in infrastructure on a vendor side No Additionally, AWS provides metadatas with tags together to helps the customers meet it No AWS points their clients to be responsible to meet such requirements, while Azure points to build solutions tracked for mobile code requirements like procedures or rest well-known solutions such as VPN. It means an ability to configure and use, however the customers need to use APIs, links a cloud layer solution with others like Active Directory or independent solutions (3rd party software, another cloud to backup data, etc.) or definitely noncloud layer, e.g. OS layer to meet such requirement. Abbr. "exc." means “Yes”, “No”, “prebuilt”, “poss.” or something else except several statements/clauses related to other meaning: for example, “Y” exc. "smth" means "smth" is difficult (ask for additional actions with APIs or similar) to meet a requirement, or "N/A". “N” exc. “smth” means “smth” is equals to “Y”. If “exc.” is followed by “N/A” or other, it means an explicitly definition that is all good but there is no information (N/A) about “smth”. Abbr. "prebuilt" means the same solution was able to use as it (besides a configuration); Abbreviation "part prebuilt" means covering not all services of certain cloud. Abbr. "poss." means a possibility to build because of outstanding a cloud (or non-cloud) object from a logical point of view. Abbr. "internal" means a possibility ("p.internal") to build or prebuilt the similar solutions allowed to extend with call for internal data, while "t.internal" points to internal cloud vendors solutions or reports. Abbr. "N/A" means there is no public information to execute a requirement as well as a need to request a third party reports from cloud vendors.

Clouds vendors explain it as “security through obscurity” matters and provides with independent auditors’ reports at the same time. It often leads to questions of trust level, ability to verify the controls and way it should be done. Industrial organizations with their security vision has relived but raised more questions on transparency instead of reducing it. These documents refer to known vulnerabilities beside the point and bring misunderstanding, e.g. there are several attacks successfully applied to Xen, VMware or other private clouds. It means an application domain that often excludes the public clouds in case of AWS and Azure. Some cases are not clear in according to the roles and responsibilities of cloud vendors and their customers. As it is not defined clearly, it makes uncertain whether the vendors should provide the customers any control opportunities; it leads to swapping responsibilities and shifting vendor job on to customer shoulders. The vendors address to their reports too much instead of providing the public details. It should be strong defined which controls are allowed to be available to the customers, which built and detailed in public documents, and the rest is covered by independent reports; ex. [Assignment: organization-defined frequency]. Any discrepancy must shift the security level from the highest to one level lower as it is in NIST. Other cases cover an announcement about compliance in alignment to certain standards on vendor side that is partially good and should be enhanced by independent analysis reports. It yields the technical details from Amazon and well-known statements multiplied with internal reports from Microsoft. CSA puts the cross references to other standards in their documents, that impact on complexity and lack of clarity in case of NIST. It makes very unobvious how the same controls related to each other and how general requirements correspond to clearly detailed requirements. Anyway, it makes a good showing to rely on differences of these requirements to improve the last and recreate new set to keep a comprehensive unity of cloud security that is signification part to remediate issues and enhance transparency of cloud controls on technical requirements more than it was according to industrial documents. Examination the following cloud solutions, such as Office365 with Cloud BES, AWS and Azure against other standards (CoBIT, NIST SP 800-53 rev.4 and ISO 27001 ’13) is a part of further research too.
