Abstract: Clouds give an intense figuring stage that empowers people and associations to perform assortment levels of undertakings, for example, utilization of online storage room, selection of business applications, improvement of tweaked PC programming, and formation of a "practical" system condition. In earlier years, the quantity of individuals utilizing cloud administrations has drastically expanded and loads of information has been put away in Cloud computing situations. Meanwhile, information breaks to cloud administrations are likewise expanding each year because of programmers who are continually attempting to misuse the security vulnerabilities of the design of cloud. In this paper, three cloud benefit models were thought about; cloud security dangers and dangers were researched in light of the way of the cloud benefit models.True cloud assaults were incorporated to exhibit the methods that programmers utilized against Cloud computing frameworks. Likewise, countermeasures to cloud security ruptures are exhibited. Keywords: Cloud computing, cloud security threats and countermeasures, cloud service models

I. Introduction Cloud computing has been included in everybody's life. It conveys applications and storage rooms as administrations over the Internet for practically no cost. The greater part of us use Cloud computing administrations regularly. For instance, we utilize electronic email frameworks (e.g. Hurray and Google) to trade messages with others; informal communication destinations (e.g. Facebook, LinkedIn, MySpace, and Twitter) to impart data and remain in contact to companions; on-request membership administrations (e.g. Netflix and Hulu) to sit in front of the TV shows and motion pictures; cloud stockpiles (e.g. Humyo, ZumoDrive, and Dropbox) to store music, recordings, photographs and reports on the web; joint effort apparatuses (e.g. Google docs) to work with individuals on a similar record continuously; and online reinforcement devices (e.g. JungleDisk, Carbonite, and Mozy) to consequently move down our information to cloud servers. Cloud computing has additionally been included in organizations; organizations lease administrations from Cloud computing specialist co-ops to decrease operational expenses and enhance income. For instance, the social news site, reddit, rents Amazon Elastic Compute Cloud (EC2) for their advanced announcement board benefit. The advanced photograph sharing site, Smug Mug, rents Amazon S3 (Simple Storage Service) for their photograph facilitating administration. The automaker, Mazda USA, rents Rackspace for their promoting ads. The product organization, HR Locker, rents Windows Azure for their HR programming administration. There is doubtlessly the comfort and minimal effort of Cloud computing administrations have changed our day by day lives; in any case, the security issues related with Cloud computing make us defenseless against cybercrimes that happen each day. Programmers utilize an assortment of procedures to access mists without legitimate approval or disturb benefits on mists keeping in mind the end goal to accomplish particular targets. Programmers could trap a cloud into regarding their illicit action as a substantial occasion, in this manner, increasing unapproved access to the data put away in the cloud. Once the correct area of information is found, programmers take private and touchy data for criminal exercises. As indicated by Data Loss DB, there were 1,047 information rupture episodes amid the initial nine months of 2012, contrasted with 1,041 occurrences amid the whole year of 2011. Epsilon and Stratford were two information rupture casualties. In the information spillage mischance, Epsilon released a large number of names and email addresses from th card numbers and 860,000 client names and passwords were stolen. Programmers could likewise exploit the huge registering energy of mists to flame assaults to clients who are in the same or diverse systems. For example, programmers leased a server through Amazon's done an assault to Sony's PlayStation Network. In this manner, a great comprehension of cloud security dangers is essential with a specific end goal to give more secure administrations to cloud clients. In this paper, area 2 displayed an outline of cloud administration models. Area 3 examined the cloud security dangers and dangers from three different viewpoints. Related genuine cloud endeavors were incorporated. Area 4 acquainted countermeasures with cloud security breaks. At long last, the conclusions and future work were exhibited in the last area.

II. Cloud Service Models Cloud computing includes conveying processing assets (e.g. servers, stockpiles, and applications) as administrations to end clients by Cloud computing specialist organizations. End clients access on-request cloud benefits through web programs. Cloud computing specialist co-ops offer particular cloud benefits and guarantee the nature of the administrations. Essentially, Cloud computing incorporates three layers: the framework layer, the stage layer, and the application layer. The base layer is the framework layer, which incorporates computational assets, for example, foundation of servers, system gadgets, memory, and capacity. It is referred to as Infrastructure-as-an administration (IaaS). The computational assets are made accessible for clients as on-request benefits. With the utilization of virtualization innovation, IaaS gives virtual machines that permit customers to assemble complex system frameworks. This approach not just lessens the cost in purchasing physical gear for organizations, it additionally facilitates the heap of system organization since IT experts are not required to constantly screen the wellbeing of physical systems. A case of a Cloud computing specialist co-op of IaaS is Amazon'sEC2. It gives a virtual figuring condition with web benefit interfaces; by utilizing the interfaces, clients can send Linux, Solaris or Windows based virtual machines and run their own particular custom applications. The center layer is the stage layer and is referred to as Platform-as-a-Service (PaaS). It is intended to give an improvement stage to clients to plan their particular applications. Administrations gave by this cloud display incorporate apparatuses and libraries for application improvement, permitting clients to have control over the application arrangement and design settings. With PaaS, engineers are not required to purchase programming advancement instruments, in this manner diminishing the cost. GoogleApps is a case of PaaS; it is a suite of Google apparatuses that incorporates Gmail, Google Groups, Google Calendar, Google Docs, Google Talk, and Google Sites. It permits clients to redo these devices all alone area names. Windows Azure is another PaaS supplier. It empowers clients to assemble applications utilizing different dialects, apparatuses or structures. Clients can then incorporate the applications into their current IT situations. At long last, the top layer is the application layer, otherwise called Software-as-a-Service (SaaS). This layer permits clients to lease applications running on mists as opposed to paying to buy these applications. In view of its capacity to decrease costs, SaaS is prominent among organizations that convey their organizations. Groupon is an illustration that utilizations SaaS. With the utilization of the online bolster arrangements gave by Groupon, Zendesk forms its a huge number of every day client tickets all the more proficiently, consequently giving a superior client benefit. Marathon Data Systems is another case that offers SaaS. It gives answers for field administrations, for example, bug control, grass and arranging, warming, ventilating, plumbing, janitorial, house keeper, and cover cleaning administrations. Table 1 indicates cases of Cloud computing specialist co-ops concentrated on three cloud benefit models.

III. Taxonomy Of Cloud Security Threats Three cloud benefit models (SaaS, PaaS and IaaS) not just give distinctive sorts of administrations to end clients additionally unveil data security issues and dangers of Cloud computing frameworks. To start with, the programmers may mishandle the strong processing ability gave by mists by directing unlawful exercises. IaaS is situated in the base layer, which specifically gives the most effective usefulness of a whole cloud. It augments extensibility for clients to alter a "reasonable" domain that incorporates virtual machines running with various working frameworks. Programmers could lease the virtual machines, investigate their setups, discover their vulnerabilities, and assault other clients' virtual machines inside a similar cloud. IaaS additionally empowers programmers to perform assaults, e.g. beast compelling breaking, that need high processing power. Since IaaS bolsters numerous virtual machines, it gives a perfect stage to programmers to dispatch assaults (e.g. dispersed foreswearing of administration (DDoS) assaults) that require an extensive number of assaulting occasions.

Second, information misfortune is an imperative security danger of cloud models. In SaaS cloud models, organizations utilize applications to process business information and store clients' information in the server farms. In PaaS cloud models, designers utilize information to test programming honesty amid the framework advancement life cycle (SDLC). In IaaS cloud models, clients make new drives on virtual machines and store information on those drives. In any case, information in each of the three cloud models can be gotten to by unapproved interior workers, and additionally outer programmers. The inward representatives can get to information purposefully or accidently. The outer programmers access databases in cloud conditions utilizing a scope of hacking systems, for example, session capturing and organize channel listening stealthily. Third, conventional system assault techniques can be connected to disturb three layers of cloud frameworks. For instance, web program assaults are utilized to misuse the confirmation, approval, and bookkeeping vulnerabilities of cloud frameworks. Noxious projects (e.g. infection and Trojan) can be transferred to cloud frameworks and can bring about harm. Malevolent operations (e.g. metadata mocking assaults) can be installed in a typical order, go to mists, and executed as legitimate occurrences. In IaaS, the hypervisor (e.g. VMware vSphere and Xen) directing authoritative operations of virtual occurrences can be bargained by zero day assault. It is important to distinguish the conceivable cloud dangers keeping in mind the end goal to actualize better security components to ensure Cloud computing situations. In the accompanying subsections, we investigated security dangers introduced in mists from three points of view: mishandle utilization of cloud computational assets, information ruptures, and cloud security assaults. Late certifiable cloud assaults were additionally included to show the methods that programmers utilized as a part of abusing the vulnerabilities of cloud frameworks.

3.1. Abuse Use of Cloud Computational Resources Previously, programmers utilized various PCs or a botnet to create an extraordinary measure of figuring force keeping in mind the end goal to direct digital assaults on PC frameworks. This procedure is confounded and can take months to finish. These days, an effective figuring foundation, including both programming and equipment segments, could be effortlessly made utilizing a straightforward enlistment prepare in a Cloud computing specialist organization. By exploiting the common processing energy of cloud systems, programmers can fire assaults in a brief span. For instance, beast constrain assaults and DoS assaults can be propelled by mishandling the energy of Cloud computing. An animal compel assault is a method used to break passwords. The accomplishment of this assault is significantly dependent on intense processing capacity since a huge number of conceivable passwords are should have been sent to an objective client's record until it finds the right one to get to. Cloud computing framework gives an impeccable stage to programmers to dispatch this kind of assault. Thomas Roth, a German specialist, showed an animal compel assault operating at a profit Hat Technical Security Conference. He figured out how to split a WPA-PSK shielded system by leasing a server from Amazon's EC2. In roughly 20 minutes, Roth let go 400,000 passwords for each second into the framework and the cost of utilizing EC2 administration was just 28 pennies for each moment. DoS assaults endeavor to upset a host or system asset with a specific end goal to make honest to goodness clients not able to get to the PC benefit. They arrive in an assortment of structures and go for an assortment of administrations. By and large, they are arranged into three fundamental sorts: utilization of rare, restricted, or non-sustainable assets, devastation or adjustment of setup data, and physical annihilation or change of system segments. Among them, flooding is the most well-known route in which programmers disintegrate the casualty's framework with the utilization of a mind-boggling number of false demands; in this manner, the administrations to real clients are blocked. At the point when the flooding assault is connected to cloud administrations, two sorts of DoS could occur in Cloud computing frameworks: coordinate DoS and circuitous DoS. At the point when a cloud server gets an extensive volume of overwhelmed solicitations, it will give more computational assets to adapt to the pernicious solicitations. At long last, the server debilitates its full ability and an immediate DoS is struck all solicitations from honest to goodness clients. Also, the surge assault could make roundabout DoS different servers in a similar cloud when the servers share the workload of the casualty server, which comes about a full absence of accessibility on the majority of the administrations. Cloud computing administrations can be utilized to send a lot of parcels to organizations' systems. For instance, two security experts, Bryan and Anderson, propelled cloud-based DoS assaults to one of their customers keeping in mind the end goal to test its availability with the assistance of Amazon's EC2 cloud foundation. By spending just $6 to lease virtual servers on EC2, they utilized a hand crafted "Thunder Clap" program to effectively surge their customer's server and made the organization inaccessible on the Internet. Another DoS assault illustration was talked about on a Danish developer's, Jesper Nøhr blog. As per his

DOI: 10.9790/0661-1902053643 www.iosrjournals.org 38 | Page The Vulnerabilities of Cloud Computing: Security Threats report, Bitbucket, an online facilitating administration organization facilitated by Amazon, was assaulted by gigantic scale DDoS assaults utilized by two flooding methods: a surge of UDP parcels and a surge of TCP SYN association demands. The assaults made the organization end up plainly inaccessible and thus, numerous engineers lost access to ventures facilitated on Bitbucket.

3.2. Data Breaches 3.2.1. Malicious Insider Security dangers can happen from both outside of and inside associations. As indicated by the 2011 Cyber Security Watch Survey directed on 607 organizations, government officials, experts and advisors, 21% of digital assaults were created by insiders. 33% of the respondents thought the insider assaults were all the more exorbitant and harming to associations. The most widely recognized inside assaults were unapproved access to and utilization of corporate data (63%), unexpected presentation of private or delicate information (57%), infection, worms, or different pernicious codes (37%), and robbery of licensed innovation (32%). The vulnerabilities of Cloud computing to malevolent insider are: indistinct parts and duties, poor implementation of part definitions, need-to-know standard not connected, AAA vulnerabilities, framework or OS vulnerabilities, deficient physical security techniques, difficulty of handling information in scrambled shape, application vulnerabilities or poor fix administration . While moving information and applications to Cloud computing conditions can grow organizations, vindictive harm of an association's delicate data assets could imperil the whole casualty association's operation. There are three sorts of cloud-related insider dangers: the rebel head, insiders who abuse cloud vulnerabilities, and the insiders who utilize the cloud to direct evil movement. Rebel chairman has benefit to take unprotected documents, animal constrain assault over passwords, and download clients' information from the casualty association. Insiders who misuse cloud vulnerabilities attempt to increase unapproved access to secret information in an association; they could make a fortune by offering the delicate data, or utilize the data for their future organizations. Insiders who utilize the cloud to lead accursed action do assaults against its own manager's IT framework. Since the insiders know about the IT operations of their own organizations, the assaults are for the most part hard to be followed utilizing criminological investigation.

3.2.2. Online Cyber Theft Cloud computing administrations furnish clients with intense preparing ability and huge measures of storage room. With their economical cost, organizations could move their business into mists so they don't have to purchase th handle activity from clients and guests. For instance, Netflix leases registering space from Amazon Web Services (AWS) to give membership administration to staring at the TV scenes and motion pictures. Dropbox offers distributed storage administration to clients for putting away terabytes of information. Cloud-based administrations are currently turning into a piece of our every day lives. Meanwhile, the delicate information put away on mists turns into an appealing focus to online digital burglary. As indicated by the investigation of information breaks of 209 worldwide organizations in 2011, 37 percent of information rupture cases included malevolent assaults. The normal cost per bargained record is $222. Online retailer Zappos (possessed by cloud supplier Amazon) was the casualty of online digital robbery. Just about 24 million customer records may have been bargained in the rupture. The traded off data incorporates names, email addresses, charging and transporting addresses, telephone numbers, the last four digits of Visa numbers, and additionally encoded renditions of record passwords. Taking information put away on mists could occur on person to person communication destinations. Long range interpersonal communication locales, for example, Twitter, MySpace, and Facebook, have pulled in individuals who utilize them to collaborate with companions in their day by day lives. USA Today found that 35 percent of grown-ups Internet clients have a profile on no less than one long range informal communication webpage. These systems give a stage to clients to impart data to others, e.g. individual profile (sex, birthdate, email, phone, and instruction) and advanced media (music, photographs and recordings). In any case, that private information can be hacked by online digital criminals, on the off chance that they figure out how to get to the mists. For instance, LinkedIn, the world's biggest expert systems administration site that claims 175 million clients, announced that their secret key database was bargained in a security break. Around 6.5 million hashed passwords were stolen and posted onto a Russian web discussion. More than 200,000 of these passwords have been split. The online digital criminals could utilize stolen passwords to get to clients' records and to dispatch vindictive assaults to clients. Dropbox has affirmed that its clients experienced a spam assault. Usernames and passwords stolen from different sites were utilized to sign into Dropbox clients' records. Moreover, a stolen secret word was utilized to get to a Dropbox worker's record containing a venture archive with client email addresses. At that point, the programmer sent spam messages about online club and betting locales to different clients.

Online digital criminals could likewise take the benefit of the processing power offered by Cloud computing specialist organizations to dispatch assaults. Amazon's EC2 cloud administration was utilized by programmers to trade off private data. By joining Amazon's EC2 benefit with fake data, programmers leased a virtual server and propelled an assault to take customers' information from Sony's PlayStation Network. The programmers didn't break into the Amazon servers amid the occurrence; however the individual records of more than 100 million Sony PlayStation Network supporters were traded off.

3.3. Cloud Security Attacks 3.3.1. Malware Injection Attack Electronic applications give dynamic website pages to Internet clients to get to application servers by means of a web program. The applications can be as basic as an email framework or as entangled as a web based keeping money framework. Think about has demonstrated that the servers are powerless against online assaults. As per a report by Symantec, the quantity of web assaults in 2011 expanded by 36% with more than 4,500 new assaults every day. The assaults included cross site scripting, infusion defects, data spillage and disgraceful mistake dealing with, broken verification and session administration, inability to confine URL get to, despicable information approval, shaky correspondences, and pernicious document execution. Malware infusion assault is one class of electronic assaults, in which programmer’s abuse vulnerabilities of a web application and insert noxious codes into it that progressions the course of its typical execution. Like online applications, cloud frameworks are additionally powerless to malware infusion assaults. Programmers make a malevolent application, program, and virtual machine and infuse them into target cloud benefit models SaaS, PaaS and IaaS, separately. Once the infusion is finished, the noxious module is executed as one of the legitimate occurrences running in the cloud; then, the programmer can do whatever s/he yearnings, for example, listening in, information control, and information robbery. Among the majority of the malware infusion assaults, SQL infusion assault and cross-site scripting assault are the two most basic structures. SQL infusion assault expanded 69% in Q2 2012 contrasted with Q1, as indicated by a report by secure cloud have supplier FireHost. FireHost said that amongst April and June, it blocked about half-million SQLi assaults. SQL infusions target SQL servers that run helpless database applications. Programmers abuse the vulnerabilities of web servers and infuse a malignant code keeping in mind the end goal to sidestep login and increase unapproved access to backend databases. In the event that effective, programmers can control the substance of the databases, recover secret information, remotely execute framework charges, or even take control of the web server for further criminal exercises. Sony's Play Station was a casualty of a SQL infusion assault. Sophos Lab's blog detailed that a SQL infusion assault has been effectively used to plant unapproved code on 209 pages advancing the PlayStation recreations, "Sing Star Pop" and "Divine force of War". SQL infusion assaults can be propelled by a botnet. The Asprox botnet utilized a thousand bots that were furnished with a SQL infusion unit to flame a SQL infusion assault. The bots first sent encoded SQL questions containing the endeavor payload to Google for looking web servers that run ASP.net. At that point, the bots began a SQL infusion assault against the sites came back from those inquiries. Generally, around 6 million URLs having a place with 153,000 diverse sites were casualties of SQL infusion assault by the Asprox botnet. A situation that shows SQL infusion assaulting cloud frameworks was represented in. An online retail SaaS application that permits various retailers to have their items and offer them through SaaS was utilized. The strategy of misusing helplessness and getting to backend database was clarified in points of interest. Cross-site scripting (XSS) assaults are viewed as a standout amongst the most malevolent and perilous assault sorts by FireHost. 27% of web assaults, cross-webpage scripting assault, were effectively hindered from making hurt FireHost customers' web applications and databases amid Q2 2012. Programmers infuse malevolent scripts, for example, JavaScript, VBScript, ActiveX, HTML, and Flash, into a defenseless element website page to execute the scripts on casualty's web program. A short time later the assault could direct illicit exercises (e.g. execute noxious code on the casualty's machine and take session treat utilized for approval) for getting to the casualty's record or deceiving the casualty into clicking a malevolent connection. Scientists in Germany have effectively shown a XSS assault against Amazon AWS Cloud computing stage. The defenselessness in Amazon's store permitted the group to capture an AWS session and access to all client information. The information incorporates confirmation information, tokens, and even plain content passwords.

3.3.2. Wrapping Attack At the point when a customer demands administrations to a web server through a web program, the administration is communicated utilizing Simple Object Access Protocol (SOAP) messages that are transmitted through HTTP convention with an Extensible Markup Language (XML) arrange. To guarantee DOI: 10.9790/0661-1902053643 www.iosrjournals.org 40 | Page The Vulnerabilities of Cloud Computing: Security Threats secrecy and information honesty of SOAP messages in travel amongst customers and servers, a security instrument, WS-Security (Web Services Security), for web administration is connected. It utilizes advanced mark to get the message marked and encryption strategy to scramble the substance of the message. This makes the customer verified and the server can approve that the message is not altered amid transmission. Wrapping assaults utilize XML signature wrapping (or XML revising) to abuse a shortcoming when web servers approve marked solicitations. The assault is done amid the interpretation of SOAP messages between a genuine client and the web server. By copying the client's record secret word in the login period, the programmer installs a sham component (the wrapper) into the message structure, moves the first message body under the wrapper, replaces the substance of the message with malevolent code, and after that sends the message to the server. Since the first body is as yet legitimate, the server will be deceived into approving the message that has really been changed. Subsequently, the programmer can increase unapproved access to secured assets and process the proposed operations. Since cloud clients typically ask for administrations from Cloud computing specialist organizations through a web program, wrapping assaults can make harm cloud frameworks also. Amazon'sEC2 was found to be helpless against wrapping assaults in 2008. The exploration indicated EC2 had a shortcoming in the SOAP message security approval instrument. A marked SOAP ask for of a genuine client can be caught and altered. Subsequently, programmers could take unprivileged activities on casualties in mists. Utilizing XML account signature wrapping method, specialists likewise exhibited a record commandeering assault that misused defenselessness in the Amazon AWS. By adjusting approved carefully marked SOAP messages, the scientists could acquire unapproved access to a client's record, erase and make new pictures on the customer'sEC2 example, and perform other regulatory undertakings.

IV. Countermeasures A Cloud computing framework incorporates a cloud specialist organization, which gives registering assets to cloud end clients who expend those assets. Keeping in mind the end goal to guarantee the best nature of administration, the suppliers are in charge of guaranteeing the cloud condition is secure. This should be possible by characterizing stringent security arrangements and by applying propelled security advances.

4.1. Security Policy Enhancement With a legitimate charge card, anybody can enlist to use assets offered by cloud specialist organizations. This makes programmers exploit the effective registering energy of mists to direct malevolent exercises, for example, spamming and assaulting other figuring frameworks. By moderating such mishandle conduct brought on by feeble enlistment frameworks, charge card extortion checking and piece of open boycotts could be connected. Additionally, usage of security approaches can diminish the danger of manhandle utilization of cloud computational power. Entrenched tenets and controls can help arrange executives deal with the mists all the more viably. For instance, Amazon has characterized a reasonable client's arrangement and confines (or even ends) any culpable occasions at whatever point they get an objection of spam or malware coming through Amazon EC2.

4.2. Access Management The end clients' at a put away in the cloud is touchy and private; and get to control components could be connected to guarantee just approved clients can have entry to their information. Not exclusively do the physical registering frameworks (where information is put away) must be consistently observed, the activity access to the information ought to be limited by security systems. Firewalls and interruption discovery frameworks are regular devices that are utilized to limit access from untrusted assets and to screen noxious exercises. Moreover, validation benchmarks, Security Assertion Markup Language (SAML) and extensible Access Control Markup Language (XACML), can be utilized to control access to cloud applications and information. SAML concentrates on the methods for exchanging confirmation and approval choices between coordinating elements, while XACML concentrates on the system for touching base at approval choices.

4.3. Data Protection Information ruptures brought on by insiders could be either unintentional or purposeful. Since it is hard to distinguish the insiders' conduct, it is ideal to apply legitimate security apparatuses to manage insider dangers. The instruments include: information misfortune counteractive action frameworks, peculiar conduct design location devices, arrange protecting and encryption apparatuses, client conduct profiling, imitation innovation, and verification and approval advancements. These apparatuses give capacities, for example, ongoing location on observing movement, review trails recording for future criminology, and catching noxious action into distraction reports.

4.4. Security Techniques Implementation The malware infusion assault has turned into a noteworthy security worry in Cloud computing frameworks. It can be avoided by utilizing File Allocation Table (FAT) framework engineering. From the FAT table, the occasion (code or application) that a client will run can be perceived ahead of time.By contrasting the example and past ones that had as of now been executed from the client's machine, the legitimacy and in trustworthiness. Another approach to avert malware infusion assaults is to store a hash an incentive on the first administration occurrences. By picture playing out document respectability check between the first and new administration example's pictures, pernicious. Occurrences can be For XML signature wrapping assaults on web benefits, an assortment of procedures have been proposed to settle the helplessness found in XML-based advances. For instance, XML Schema Hardening system is utilized to reinforce XML Schema statements. A subset of XPath, called FastXPath, is proposed to oppose the pernicious components that assailants infuse into the SOAP message structure.

V. Conclusions And Future Work Cloud computing is in nonstop advancement keeping in mind the end goal to make distinctive levels of on-request benefits accessible to clients. While individuals appreciate benefits Cloud computing brings, security in mists is a key test. Much helplessness in mists still exists and programmers keep on exploiting these security openings. So as to give better nature of administration to cloud clients, security imperfections must be distinguished. In this paper, we analyzed the security vulnerabilities in mists from three points of view (mishandle utilization of cloud computational assets, information breaks, and cloud security assaults), included related true endeavors, and acquainted countermeasures with those security ruptures. Later on, we will keep on contributing to the endeavors in contemplating cloud security dangers and the countermeasures to cloud security breaks.
