If all the devices are virtualized, how about the Networking will be done in an virtualized environment. Present Networking technology mainly focused on Physical devices, so there is a need for network configuration in virtualized environment is there always, SDN i.e. Software Defined network is an a open source networking where programmed Networking is possible.
Our traditional network physical devices are mostly Hardawar based, growing computer change leads to a driving network change, Even cisco a major network giant in industries had came virtualization network with its own technology . So Now let us lookup how the concept is implemented .
Infrastructure layer or Data Plane : its a non -intelligence end layer ,where network switches and routers where the data forward to need layer.
Control layer 0r Control plane : it’s the intelligence layer, its the place determine how the traffic should be forwarded.
Application layer or Application Plane : services, application utilities with control level available in Application layer
All the famous social media become end-to-end encrypted now a day’s, It was started used by telegram first and all other social media messaging software started following it. WhatsApp, Viber, Facebook messenger are started using end-to-end encryption for securing data’s.
End-to-end Encryption concept is very simple, its a secure communication between both the end devices as the encryption known between this two devices only, means no other person can able see the message, even the providing server are cannot have this encrypted personal data.
As technical perspective its good move, what about law enforcement since social media is communicating through the region of the world, common question arising all over the world are if this encryption is used by fraud or illegal activities? on going debate is countries need to have a backdoor access to encryption so they can monitor the data communication between the users, but the social media’s providers point of view if security is opened, there might be chance to lose of customer.
Let’s wait what kind of changes will come be there for encryption technology.
IT industries had went a lot changes for the past ten years, traditional data center had moved to clouding, data storage is changed, entry of mobile application, resulted in BYOD services and great demand of Big data, had leads to different requirement in IT industries, old traditional vendor based certification are started losing its popularity and new neutral based certification started hitting in the marked and it has a huge demand, let us look what at certification had a huge demand in 2017.
Amazon Web Service(AWS) developer
It’s one of the Most valuable certificate in IT industries , its one the useful certificate in cloud industries.
Certified in Risk and Information System Control (CRISC)
Its security based certification in IT industries, Mainly useful for the IT professional, Project Managers and those who are related in IT Based Risk Filed.
Certified information Security Manager(CISM)
Its one of the certificate focused on managers, it gives a high over view on security polices and procedure.
Certified information system security professional (CISSP)
its also related to security, its covers overall security started from securing data, hardware, software, program. it’s focused mainly on security.
Certified information System Auditor(CISA)
this certificate is mainly focus on auditing and controlling ,Monitoring of IT assets .
VMWARE certified professional
its one of the peak growing certificate in IT industries, its mainly concentrate on virtualization and its tool for change over to cloud technology and its most needed certificate too.
Yahoo.. One of the legend in internet Era during 1990’s and 2000’s . It was globally well known to the world by its E-mail, Yahoo Finance and yahoo messenger, map, groups and its Add. they had a huge traffic to their side and had huge income during that period. later when google and Facebook and lot of social medias came in to exist yahoo lost it popularity and visitors traffics also begin to lost.
yahoo Mail is failed with google Mail, yahoo answer lost with Quora, and flickr to Instagram. Even though it have huge traffic and lot visitors the main draw back is its failed to movie with technology advance and failed to make correct decision and exact time. Mainly on search google had a huge growth. In recent year Yahoo security breach also leads to the lose confidentiality to their mail users.
Most of the yahoo services like yahoo 360, yahoo personal had stopped now. yahoo teach us a lesson what are all the mistake we should not do else we will fall . Failed to adopt new technology and raise in social media is also the cause, if changes are going we need to adopt changes if we stick on the think which we believe blindly we will fall .
Microsoft came along with Microsoft Azure, even though they entered late to cloud technology, Microsoft skype, yammer ,office 365 and one drive had made huge impact in clouding services, its one of the major changes, Exchange into 365 is reduced lot System administration task.
Google is doing a lot in the cloud , it’s google doc engine where developer can configure their own app using java and python program, same as Microsoft google had its own google drive, google for corporate e-mail account also.

Its a new concept raising in Security area, Sandbox is a type of restricted Area where untested or unverified programs or malicious code will be executed and checked . Traditional issue in security field is one the malicious code is attacked to the network then only patch or security of the code will be released. Sandbox is the solution provider even if the e-mail contained unverified program, any malicious code it will go sandbox virtualized area first and the code will be tested. after the code is executed there is no issue found in Sandbox virtualization environment the software or program will allowed in to the internal network.
If sandbox found a hacking or virus program , it will block the software and it will added as a virus batch thus it not allowing to enter our network, so we will have full secure environment.
What happen if the data encryption is used by fraud, its result in ransomware malware. Ransomware malware will encrypt the data and if you need to decrypt you need to pay for private key else your private key for decryption will be deleted and you will lose your data permanently.
It’s raising peak now a days and most of the companies are subjected to ransomware, it’s also called as cryptovirus, cryptotrojan and cryptowarm.
How its spreading ? mostly through E-mail attachments, Infected program, and compromised network.
Preventive Measure is through strong firewall setting, using Sandbox environment, having regular backup of all data, if ransomware malware infected wiping the data is best option and restore the data from back-up.
