Why Your DIY Security Data Lake Might Just Sink?>
– Anuj Magazine
As organizations continue to accumulate large amounts of data, one of the most important trends of the last few years has been the emergence of the data lake – a repository of structured, semi-structured, and unstructured data, often pooled from multiple sources, with the goal of helping organizations better understand and gain insights from their data.
The idea of the data lake is appealing because it sounds so easy – just dump all your data into one big lake and let the insights come to you.
Unfortunately, it’s not quite that simple.
Setting up and managing a secure data lake requires a commitment to ongoing data management and governance, both of which can be especially challenging when the data lake is “homemade” or “DIY”.
Security and privacy are significant concerns for any organization dealing with customer data.
DIY data lakes can leave organizations vulnerable to data breaches and other security incidents if the proper steps to secure the data lake are not taken.
Here are a few tips to help ensure your DIY data lake is secure:
1) Establish strong access policies and controls: Access controls are essential for ensuring only the right people can access data in the data lake.
That means implementing authentication and authorization measures, such as roles-based access control, to identify and grant access only to the individuals that need it.
2) Encrypt all data: Even with properly enforced access controls, data should still be encrypted in transit and at rest.
This reduces the risk of unauthorised or malicious access to the data.
3) Monitor devices and activity: Implement logging and monitoring of all data lake activities to maintain visibility into who is accessing the data, when, and for what purpose.
Logs should be regularly monitored for indications of suspicious activity.
4) Make a data retention and deletion policy: Data lakes can quickly become bloated with data if a data retention and deletion policy isn’t in place.
Set retention policies for data that should be kept and those that should be deleted on a regular basis to ensure the data lake only contains the most up-to-date data.
By following these tips, DIY data lake owners can ensure their data lake is as secure as possible and reduce the risk of data breaches or other security incidents.
While setting up a DIY data lake can be a valuable way to gain insights from data, the importance of properly managing and securing the data lake should not be underestimated.
