cloud and any outage would result in youbeing unable to access any of the data, or evendata loss as in the case of Sidekick.These technical risks aren’t the only reliabilityissues involved. What happens in case youcloud provider goes out of business? Theapplication or services you have been using forsome time now would be suddenlyunavailable. And since everything is offered asa service, there is no falling back on legacysystems being run on crutches.Reliability does not just mean the absence ofservice; It also means that the services beingsubscribed to, not being provided in theirentirety. For a consumer, a slowdown inservices being consumed can have a great losson profits. If a manager is unable to access hishosted services provider in a timely fashion, itmay result in contracts worth millions beinglost.SecuritySecurity can be broadlyclassified into threetypes – Data Security,Access Security andTransmission Security.Since the data does notreside in‐house in the case of cloudcomputing, all three factors need to be takencare of in a highly detailed manner.This is one of the first issues is with the SaaSmodel. Today, most providers focus ondelivering application by using web standardssuch as HTML, CSS and JavaScript. This leavesthem highly vulnerable to Cross Site Scripting(XSS) and other types of web attacks. A fewyears back there was a major case of Gmailbeing affected with such an XSS attack whichenables a malicious web page to get access toyour entire contact list [8] .Most of the other issues with security in cloudcomputing are the same as those of any formsof data storage outsourcing. Security issuesare numerous and data security techniquesand provisions will vary from provider toprovider, from country to country.The cloud presents a very juicy target tomalicious hackers as it represents a collectionof data from various sources in one place,which can be easily hacked into andexploited. In such cases where multipleclients’ data is being stored within the samelogical network, the security of the systembecomes as strong as the security of theweakest link, i.e. least security aware client. Ifa hacker exploits a vulnerability in onesystem, he can gain access to the data ofothers as well. This can be especially observedon shared webhosting solutions on whichmany websites are hosted.A few questions which need to be asked whenlooking at security of the cloud are: Where is the data located? Who has Access? Can you audit your provider? What kind of data segregation andsecurity systems does the provider use? What are the Disaster Recovery &Business Continuity Plans? What essential systems does the companyneed in the case of a provider outage?Final WordsAn important facet while purchasing cloudservices is the need to know the underlying10
structure and design of the hardware andsoftware. If there are not adequate controlsprovided to keep up the security andreliability of the services consumed then aconsumer can never trust someone whom healready has a bit of trust issues with. Alwaysknow that there will always be a trade‐offbetween cost and reliability & security andalways have backup plans in place in the caseof a provider outage.References[1] “Google Apps Fowntime Report: PerfectExample?”, July 25, 2010, http://administratosphere.wordpress.com/2010/03/08/google‐apps‐downtime‐reportperfect‐example/[2] “The Day After: A Brutal Week forUptime”, July 26, 2010, http://www.datacenterknowledge.com/archives/2009/07/06/the‐day‐after‐abrutal‐week‐for‐uptime/[3] “Amazon Addresses EC2 Power Outages”,July 25, 2010, http://www.datacenterknowledge.com/archives/2010/05/10/amazon‐addressesec2‐power‐outages/[4] “Storms in the cloud leave users up creekwithout a paddle”, July 26, 2010, http://arstechnica.com/microsoft/news/2008/08/storms‐in‐the‐clouds‐leaveusers‐up‐creek‐without‐a‐paddle.ars[5] “It’s Not Just You: Gmail Not Working ForMost Users”, July 27, 2010, http://mashable.com/2009/09/24/gmail‐isdown‐2/[6] “Gmail Is Down … Again”, July 27, 2010,http://mashable.com/2009/09/24/gmail‐is‐down‐4/[7] “Microsoft Loses Sidekick Users' PersonalData”, July 27, 2010, http://www.pcworld.com/businesscenter/a r t i c l e / 1 7 3 4 5 7 /microsoft_loses_sidekick_users_personal_data.html[8] “Gmail bug exposes your mail account tospammers”, July 24, 2010, http://www.engadget.com/2007/01/01/gmailbug‐exposes‐your‐mail‐account‐tospammers/[9] “Cloud computing promise still stormy withreliability issues”, July 24, 2010, http://arstechnica.com/web/news/2009/07/cloud‐computing‐promise‐still‐stormy‐with‐reliability‐issues.ars[10] “Reliability and Cloud Computing”, July 26,2010, http://www.enkiconsulting.net/blog/reliability‐and‐cloud‐computing.html[11] “Cloud computing security issues:Protecting your UC applications”, July 27,2 0 1 0 , h t t p : / /searchunifiedcommunications.techtarget.co m /tip/0,289483,sid186_gci1516270,00.html[12] “Twitter breach revives security issues withcloud computing”, July 27, 2010, http://www.computerworld.com/s/a r t i c l e / 9 1 3 5 8 9 3 /Twitter_breach_revives_security_issues_with_cloud_computing_11
