With European Union’s GDPR (General Data Protection Regulation) enforcement day inching closer and closer on May 2018, organizations really need to put their heads together and act fast on the data security. The motto of the EU regulation is clear ‘Act or face the consequence’. Any non-compliance by the organization will have to be paid in the form of a steep fine and that amount is 4% of its annual global revenues. In upcoming section, read how CASB solution helps an enterprise in data protection.

It is but pertinent that all the organizations are hiring the services of cloud providers for data storage and processing since it is not economical or feasible to store and process such humongous amount of data on-premises. So both the organization and the cloud service provider either within or outside the EU who has EU citizens’ data with them fall under the purview of GDPR.

So how do organizations and cloud service providers’ work in tandem to secure the data? In order to practice Data Loss Prevention (DLP), CASB (Cloud Access Security Broker) software hits the right target so that data can be secured and protected.

How CASB Solution Helps an Organization for Data Protection?

Organizations must audit, report and make required changes to their policies before May 2018 in order to comply with GDPR. Given the several features of a CASB solution, opting for the right CASB vendor or a solution provider should be their initial step to understanding and becoming GDPR compliant, if not handling the audit independently. With a CASB solution providers, an organization can benefit these facilities:

  • Data Security: CASB plays a key role in data security as it sits between the organizations and the cloud service providers and monitors all the activities and ensures that the security measures are in place. CASB is needed both at the proxy level wherein it ensures real-time inline security and at the API level where it provides backend security.
  • Data Identification, Monitoring, and Security: CASB identifies, monitors and secures the data. Also, encryption can be provided for processing of the sensitive data without affecting the application functionality. So whether it is the data at rest both in the organization’s on-premises infrastructure or the cloud services, or the dynamic in-transit data, it helps in quarantining the data from security risks. CASB provides for active data monitoring at all levels including the record level and the document level.
  • Visibility: A clear visibility is possible into the data structure and the cloud environment through the CASB. It provides insight into all the controls, users, data and the actions and gathers information on the authorized or unauthorized applications and their frequency of use.
  • Compliance: CASB helps in meeting the compliance standards of PCI, PII, and HIPAA etc. More importantly, it can be customized to meet the organization requirements so that both the internal as well as external security threats can be identified and acted on. Also, the security arrangements can be reviewed by the organization by audits and modifications to improve the security based on the GDPR compliance can be suggested.

Data Loss Prevention (DLP) policies for GDPR compliance

In the early phases of GDPR assessment, an organization needs to evaluate, track and understand the information flow of all the user data that it possesses; such as phone numbers, social security numbers, PINs, passwords, document numbers, passport, etc. DLP policies play an important role in monitoring the transmission of such confidential data, whether it is in motion (network traffic), in-use (endpoint actions), or at-rest (data storage). DLP policies also detect potential data breach or data-exfiltration transmission and help in preventing data loss.

Post evaluation the organization is in a better state to understand their standing for GDPR compliance and chances are that they need to build a more secure data ecosystem, this is where DLP comes into action. With DLP policies, an admin can restrict unauthorized data transfer or access from inadmissible users and devices, keeping the data secure, and organizations GDPR compliant.

In addition to the implementation of a CASB solution and its DLP policies, other measures need to be taken as well, by getting in touch with the GDPR regulators so that by the time this regulation is enforced, your organization is fully equipped to secure and protect the data of the EU citizens.
