SaaS Security Wilderness Tamed by CASB

What is SaaS Security?

With the rapid proliferation of rogue cloud applications, it becomes pertinent that new tools are implemented to protect corporate data on the cloud. The main focus is now on Shadow IT, and the growing need for flexibility has put many employee activities off the IT security department’s radar. Employees in organizations use cloud-based apps mostly categorized as Software-as-a-Service i.e., SaaS Security.

SaaS Security At Risk In Organizations

In any organization, there are applications like Microsoft Office 365 and Google Docs, etc., which are sanctioned by the IT department after due identification, consultation, and procurement. Then there is that unsanctioned app, but it can still be there, which is used for communication purposes like Skype and Yahoo IM, etc. Then there are the unsanctioned ones that pose a severe risk. Other departments download these without the consent of the IT department.

The Need For SaaS Security

When organizations cannot restrict access to users connected through Virtual Private Network (VPN), then the employees can access sensitive information on public PCs or unsafe Wi-Fi networks. Any organization’s job is to identify such risky systems and deploy a Single Sign-On (SSO) solution to protect their corporate data. High-risk data can be categorized as HR records, customer data, health data, financial data, and critical business information. Even the DNS, content delivery networks, data center management portals, and phone systems that provide essential services to businesses need to be protected from unauthorized access.

Software as a Service (SaaS) Security With CASB Solutions

The single most effective approach to gain control is by using security services provided by Cloud Access Security Brokers (CASBs). CASBs effectively mediate data between these SaaS applications and the end-user, thus restricting access and reporting any risky behaviors. CASBs either require a client installed on the device or on the network between the SaaS app and the user. It helps to intercept the traffic and take appropriate action.

The Application Program Interface (API) in any CASB solution does not require installing a client application or proxy. Here, rules are set for identifying users and a host of other parameters so that access can be restricted and controlled. CASB would send an email to the user, saying that the document may not be suitable to share it outside the organization. Then there is the API with real-time capabilities, which alerts the admin when there is unauthorized access.
