Cloud Access Security Broker (CASB) is a software service that operates between an organization's on-premises infrastructure and a cloud provider's infrastructure. A CASB acts as a security guard; it allows the organization to increase the reach of their security policies beyond their own infrastructure. According to a report by a leading analyst firm the CASB market will reach $500 million by the end of 2017 from the current $180 million. You can imagine this huge growth! Now, the question arises why there is so much hype for cloud access security broker (CASB)? This is an important point to analyze for understanding CASB and its importance in a better way.
Let us travel back to the time of Sir Thomas Elva Edison, the most illuminated and vibrant city of the world “New York” was illuminated because of Methane gas or Marsh Gas lamps, the luminous intensity of the lamps was not up to the mark. Supply was inconsistent and costly. The concept of electricity, clubbed together with electric bulbs, converted the face of “Times Square.”
The era of “Long-term Evolution” technologies is the second decade of the 21st century. With the inception of 4G bandwidth, now they are planning to phase out the culture of mobile calls. They are promoting internet telephony over it. “Bring in Your Device” or BYOD is also bringing this same culture of fast speed internet connections. A phenomenon like “cloud computing” forms the mainstay of this LTE technologies which is going to change the fate & face of various “commercial operations” and “business communications” completely.
Google Apps for Work (formerly, Google Apps for Business) offered by the technology giant, Google, is a cloud computing productivity suite. The suite includes services like Gmail, Google Slides, Google Drive, Google Docs, Google Sheets, Google Forms, Google Calendar, Google Sites, Google+, Hangouts, and Google Apps Vault.
New developments in the Internet-based services call for data security concerns. Cloud computing is one of these new developments that needs addressing. As you know, in cloud computing, you as an end-user who gets various internet-based services. You don’t need any infrastructure for these in your premises. Through cloud computing, organizations no longer have their own computer hardware, infrastructure or platforms. There are greater chances of concern here mainly because of the fact that traffic flows across the Internet and can be attacked easily. It makes sense to have email and web threat protection in the cloud.
Understanding the correlation between SIEM and CASB is an easy task when you consider CASB as a security blanket covering SIEM. If you wish to understand this relation more closely and put it in some technical terms, then first you should have this brush up of SIEM software functions. SIEM stands for “Security Information Event Management” – all these terms are self-explanatory in many ways, and when we put them together, then we are actually talking about the software that manages a hoard of activities in a given system.
Every country has a different kind of “business eco-system.” Just like any other natural eco-system, this system also varies from place to place. The way flora and fauna present in the jungle create the eco-system of a jungle, in the similar fashion; the business communities across the continents also create this “business ecosystem” as a well.
The new buzzword is cloud computing. It is the practice of making use of the network of servers/hardware/computers that are hosted by provider and available through web/Internet for multiple purposes such as storage and computing i.e. instead of on-premise servers or hardware we leverage infrastructure from some other provider. Various organizations are adopting it as it provides a multitude of benefits.
