Cloud security is challenging and any non-compliance leads to serious repercussions for enterprises. Adept CASB solution with the right DLP module work wonders.
CASB and DLP Compliment Each Other
With enterprises actively seeking cloud migration, its security is the need of the hour. Discussions on cloud security are becoming more and more frequent underscoring the importance of protecting confidential data on the cloud. While the DLP experts focus on data loss prevention technologies, CASB (Cloud Access Security Brokers) solutions are not far behind and companies often approach cloud security vendors for solutions on safeguarding their intellectual property. But the question that arises here is, what do the enterprises select? Do they opt for DLP or CASB solutions? We try to answer this query here but we don’t argue in favor of one solution over another. That reason is that the security needs of every enterprise are different and it should be considered to ensure adequate coverage. The most likely questions that arise are:
- What are the goals of the enterprise?
- Is its data loss prevention just limited to the cloud?
- Does it want to protect data beyond the cloud boundaries like endpoint coverage, discovery and network protocols?
Most of the enterprises would want to protect their data not only on the cloud but also from anywhere and everywhere including the network, endpoint, file storage and workstations.
- Network, Endpoint, and Discovery including the Cloud – The enterprises should not assume that their traditional security tools to protect the network, endpoint, and discovery would be enough for the cloud also. The cloud storage is so widespread that it becomes absolutely necessary that enterprises upgrade or change their existing security to include the sensitive data stored on the cloud also.
- Not mutually-exclusive – Comprehensive cloud security coverage can be provided by implementing both DLP and CASB solutions. Hence, it is not enough that enterprises depend on only one and not the other. A complete solution can be attained by employing both even though there is a certain overlap between the two solutions. The best solution is when cloud security vendors provide advanced CASB solutions that are equipped with DLP modules as well to integrate the entire cloud security envelope.
- Data Detection Capabilities – DLP experts have been bettering their DLP sensitive data detection capabilities and have developed some extensive and flexible methods that give accurate and effective detection of sensitive data when applied in layers. Also, CASB solutions are very efficient in implementing great detection methods that are effective and useful at the same time. Since DLP solutions provide accurate sensitive data protection, it would make sense for organizations to choose their CASB solutions in such a way that they ensure that DLP coverage is also provided therein to leverage partnerships for effective solutions.
DLP Solutions for Cloud Data Security
The organizations should actively pursue implementation of Data Loss Prevention tools so that there is no misappropriation of confidential data. DLP solutions help enterprises to secure the data over networks, endpoint, discovery, and cloud with a layered approach. When any suspicious activity is detected then this can be reported. The data is then kept out of bounds for the malicious user through various appropriate means like reporting or alerting any such malicious attempts towards data thefts etc. The admin can initiate policies for access control and the password reset can be enabled so that there is no unauthorized access of the data. When an employee leaves an organization, then stricter enforcement policies can be implemented which scans his personal devices for sensitive data and destroys it; thus preventing the files from being wrongly accessed or copied. When an employee leaves his job, it is the role of the DLP to ensure that the sensitive data remains within the organization and does not move out with him intentionally or unintentionally. In total, DLP ensures that the crucial information of an enterprise is well managed. Attrition by employees is common in organizations and hence appropriate measures are to be taken to safeguard the confidential data. Effective implementation of Data Loss Prevention (DLP) solutions help enterprises to achieve safeguarding of the sensitive data and achieve compliance.
CASB Solutions with the right DLP modules is definitely the best-fit cloud security solution for the enterprises who are seeking to protect their sensitive data after cloud adoption.
