Your Quick Guide To Cloud Access Security Brokers
Many enterprises have been wary or outright refused to adopt cloud applications like Office 365, Salesforce and Google Apps because of compliance and security concerns. Several others have assumed that these applications are secure – but are they really?
This is where a Cloud Access Security Broker (also known as a CASB) can step in.
What Is A Cloud Access Security Broker?
Cloud Access Security Brokers solutions are a group of security tools which help organizations safely implement and enable cloud apps and devices which are mobile. These solutions have the ability of “proxying” traffic between a cloud app and a user. When proxied, these tools provide four key features:
· Data security: This includes data leakage prevention, access control, and encryption.
· Visibility: This includes security alerts, audit logs, and compliance reports.
· Compliance: This helps organizations address many compliance requirements including who, what, where, when and why information is being accessed and includes intuitive auditing of user behaviour.
· Threat Prevention: This includes the ability to identify any access form suspicious devices, hosts, locations and more.
Cloud Apps Are Not Always Secure
Contrary to popular belief, not all cloud applications are secure. SaaS application providers do their best to ensure that their products are as secure as they can possibly be before releasing them (they are, after all, asking your organization to trust their organization with your critical data). Even though they may hire the best in IT security to help in the development of their products, there are often holes present.
Cloud developers placed most of their security focus on the following:
· Malware outbreaks
· Denial of service (DoS) attacks
· Widespread data exfiltration
But there is another group of security risks which those who use cloud apps may face and which vendors do not pay nearly as much attention to. These risks include the leakage of sensitive and critical corporate data.
When sensitive data is stored in a cloud app and is not properly controlled, a number of undesirable outcomes may occur:
· Information may be accidentally or maliciously leaked
· Credentials may be stolen
· You may be found to be out of regulatory compliance and penalized
These risks are outside of the control of the cloud app provider, which means that you must take extra steps to ensure that you secure your data against risk.
At the end of the day, securing your data against lost or any other risks is your responsibility and not that of a cloud provider.
Choosing The Right Broker For Your Firm
There are three requirements which must be fulfilled when looking into your options for a cloud access security broker:
· High visibility and ultimate control. This includes across sanctioned and unsanctioned applications.
· Accurate and efficient sensitive data safeguarding. The tool should feature state of the art cloud DLOP detection mechanisms.
· Scalability. The cloud brokerage tool you use should be able to support all cases you have now and feature a scalable architecture so that it will continue to support your organization in the future while also providing rapid app coverage.
