Boeing must consider following thesecurity mechanisms and protocols to be in place for ensuring the privacy andsecurity of the discussions focused on some private information, as Unifiedcommunications systems are also vulnerable to various attacks, to prevent thesethe voice traffic must be end to end and must be encrypted end to end, toprotect the most sensitive traffic Boeing can make Unified communicationssecured by employing the following mechanisms.

1)   Securingthe communications over internet protocol by authenticating and encrypting eachIP packet of the session, this can be achieved by making use of internetprotocol communications suite (IPsec), IPsec usually operates at internet layerof the Internet protocol suite which is based on end to end security scheme.2)   EmployingTransport layer security, (RFC 2246) it runs on top of transmission controlprotocol at layer 4 protocol, there are both pros and cons of transport layersecurity:Pros:·      Itis one of the recommended security schemes for session initiation protocol, Networkaddress translator works effectively when employed with TLS over an IPsec, TLSprovides User based end to end authentication as compared to data originauthentication.Cons:·      TLSrequires certificate validation and certificate management by both client andserver, and moreover it runs on top of transmission control protocol which isconnection oriented, when there are several hundreds and thousands of TCP basedconnections the scaling and memory consumption issues arises, Hence TLS cannotsecure end to end voice over protocol communications.3)   HavingSecure Realtime protocol in place, the main moto of SRTP is to provideencryption message authentication, integrity and replay protection in theapplications in which data is unicasted and multi casted.

4)   EnablingVirtual private network for remote users, for remote users and while connectingto Small business offices it is better to install VPN at both ends, thisensures that the connected devices over VPN form an encrypted tunnel as thevirtual network keeps all the traffic safe.5)   Usingstrong passwords, this is the most overlooked mechanism but yet most importantto prevent data breach, Strong passwords should be used wherever the passwordis required in UC systems, the weak passwords can be easily attacked and theattacker can login and make calls as you with the acquired credentials,Wherever UC system’s requires user login, it is feasible to follow or make useof Diginum’s UC solution which prevents these threats by generating strongpasswords by default.  2. Boeing enjoyed some benefits by deploying Unified communication system overconverged ip which resulted in increase in productivity and efficiency atvarious levels , and decreasing the conferencing costs before deploying UCBoeing has spent double digits on web conferencing, by deploying UC the webconferencing costs are leveled up as most of the Boeing employees started usingdesktop sharing services on UC systems and making use of all of itscapabilities instead of using third party vendor services, this resulted inreducing 15% annual costs for using audio conferencing. Boeing has a reputationfor being one of the innovative companies on deciding to deploy unifiedcommunications.As per research and survey most of the mid-sizedcompanies are ahead based on the usage of UC, According to Forrester 40% of themidsize companies have deployed UC systems compared to 29% of all firms, Betterproject management, improved team management and problem solving are the majorbenefits of UC systems,  According to Forrester90% of the midsize firms were satisfied with the gains after deploying UCsystems, the next major benefit for these firms by deploying UC was fasterdecision making, enhanced customer experience, improved relationship withsuppliers and partners and improved user experience from social mediacollaboration, hence according to research and survey the benefits enjoyed bythe midsize firms and Boeing mirror each other, the main benefit was increasedin productivity and cost savings.3. If I was the CIO at Boeing I wouldimplement the following capabilities of Unified Communication to enhance thecommunication, productivity and further reduction in costs, *Unified Messaging: It is basically an integration of fax, electronic mails,messages notifications, voice, it allows all of its users to access all thesemessages from anywhere within any terminal, most Um products employ advancedcalls and message management capabilities including find me and follow me.

Withthe new presence capabilities, the need for UM Machines to act as answeringmachines is reduced, and it is moving towards real time connectivity with theworking professionals(individuals).* Speech Access and Personal Assistant:as named assistant It makes individual job easier, using which individuals canuse speech commands to access inbox, calendar, directory with ease. PersonalAssistants also does intelligent screening and filtering of the messages andallows users to search their schedule, calendar, contacts and several otherfunctions.* Business process integration: one ofthe important functionality or entity of UC solution is integrating withbusiness processes and workflow applications.

The main milestone of businessprocess integration is the elimination of human latency, In many businessprocesses today the process comes to halt until someone provides any informationto proceed to next step , UC reduces this delay of contacting next person in a series of steps or by proposing an adhocmeeting or by setting up a conference call to resolve an issue, with voiceenabled business process and applications communication can be initiated withinthe application by making it easier to notify while trying to resolve aproblem.* Mobility: In Unified Communication Systems, the mobile wireless devices are usedfor initiating voice and video communications. Thus by integrating the mobiledevice with users voice and the communications services with the enterprisecommunications allows the individuals to do their regular jobs irrespective oftheir location. By using the Unified Communications enhanced features likeclick to launch conference and Instant messaging for wireless mobile deviceusers allows individuals to participate in the conferences and access some ofthe features which they can access in the office, and hence improving theirproductivity when on mobile.References:·      http://searchunifiedcommunications.techtarget.com/feature/What-UC-is-and-isnt·      https://www.avaya.com/blogs/archives/2013/11/five-unique-ways-that-midsize-firms-deploy-unified-communications.html·      http://www.digium.com/blog/2013/03/14/7-tips-for-effective-uc-security/·      http://blog.ezuce.com/three-ways-to-secure-virtual-unified-communications/
