Companies are now turning to data as one of the most important assets in their businesses, and data engineers are in the midst of managing and improving this asset and its effectiveness. In addition, the integration of data engineering with the use of cloud computing offers scalability, accessibility, and reduced expenses. However, there are security challenges that come with this integration that need to be solved.
It is essential to know the rates and causes of cloud security incidents in order to identify the vulnerabilities of the cloud systems. The cost of security incidents in businesses has shockingly
As a data engineer, you are in a position to manage the flow of data in a society that is constantly in evolution. This responsibility is very important in today’s organizations, and if not given due attention, it can affect its overall performance. With the increasing use of
It is now evident that cloud security is no more a concern only within the IT department. It has become a crucial factor in the overall business process and productivity. Why is this so important? It is because any wrongdoing or negligence in the system may lead to adverse consequences such as system failures that interrupt business flow, bad image, and breach of data privacy.
However, a problem I often see businesses struggle with is that they have their cloud platforms varied and the security tools they use are specific to each ecosystem including the AWS, Azure, or Google Cloud Services. It is possible to become an expert in one system, and this may not allow you to easily transfer your skills to another system.
That said, there is a solution to this challenge in the form of an approach that can work on any platform. This means that one can find a number of security principles and practices that are not aligned with any particular vendor to develop a solution that can scale across different clouds. In this piece, I’ll list down the basic principles that a data engineer should know about cloud security and share some insights on the current developments in the field.
Key Fundamentals of Cloud Security for Data Engineers
Data Encryption
Encryption is one of the most effective methods of ensuring that information cannot be obtained by unauthorized persons with ease. When data is stored (At Rest) on the cloud, generally, there are commonly used encryption standards such as Advanced Encryption Standards (AES) with a 256-bit key by the leading cloud service providers. For instance, in AWS, users can simply secure their S3 storage buckets by configuring the encryption settings.
To secure data while it’s being transferred from one point to another point (In Transit) on the network, infrastructure upholds TLS (Transport Layer Security) which encrypts communication between services.
Access Control and Identity Management
The allocation of access control helps in preventing the occurrence of attacks by implementing the notion of least privilege to users and applications and granting them only the required access to perform their tasks on the cloud platforms such as GCP IAM, AWS IAM, or Azure Active Directory where administrators use tools for permission and identity management. The provided example showcases an IAM policy in AWS designed specifically for limiting access to S3 buckets.
Network Security
The basic infrastructure of cloud security comprises a network system that has features such as Virtual Private Cloud (VPC), network access control lists (NACLs), and firewalls that regulate incoming and outgoing traffic. For instance, in Azure, we can create a Network Security Group (NSG) to filter traffic as shown below.
Secure Data Storage and Processing
Cloud data must be kept safe while still being easily accessible for processing purposes. Technologies like Bucket Lock in Google Cloud Storage and AWS S3 Object Lock are designed with features that enable immutable data storage in the native environment.
Monitoring and Auditing
This makes it possible to detect threats in cloud environments since user actions and system events are examined as well as AWS CloudTrail or Azure Monitor logs for any anomalies. Here is a demonstration of how to activate CloudTrail for an AWS account.
Compliance and Data Governance
Compliance frameworks like GDPR or HIPPA and standards such as SOC 2 require data engineers to incorporate security measures to protect sensitive data adequately. In order to remain compliant with the regulations in place and maintain security standards for information classification and tagging of data, these processes should be conducted by data engineers in collaboration with relevant security teams.
As an example of this practice in action, Azure Purview has the capability to automatically categorize data based on the policies that have been applied.
Securing Data Pipelines
Data pipelines can also be susceptible to man-in-the-middle attacks or incorrect configuration if misshapen by individuals in the middle of a communication channel or if settings are misapplied or misaligned. When choosing among the available candidates for your data pipeline, it is recommended to use either AWS Glue or Apache Airflow as they both provide ways of connecting to your data in a secure manner.
For example, the following is a sample setup guide on Apache Airflow which demonstrates the application of an encryption process for enhancing security.

A major advantage of this methodology is that it focuses on the validation of the user identity, the device, and the access rights that are to be granted. Thus, employing tools that are compatible with various platforms enables data engineers and security personnel to adopt this very effective protective measure in different cloud environments.
The Development of Cloud Security Products
In a world where cloud services are commonly used and architecture is rather complex, securing systems throughout the systems is not an easy task. This has led to the development of cloud security management tools, which ideally should be able to integrate with other tools to enhance the work of the security teams. The main aim is to enforce the implementation of security policies and gain control and visibility of the different cloud stacks. This should ensure that security measures are put in place irrespective of the technology that underlies it.
In Summary
Security in the changing world of the cloud is like going on an adventure, and that is a good thing. It is important to deal with security concerns and vulnerabilities when they surface – this puts you in the lead. Zero trust frameworks offer important validations when it comes to handling security issues while the unified security architecture guarantees that policies are well enforced and there is a proper view.
But the architectural design of cloud environments is still in the process of evolving, and they need to be adaptable and proactive in order to enhance the shielding.
Although all the strategies mentioned here and the ongoing efforts to match up with the advancements can be used to enhance the security of major cloud infrastructure, the threat cannot be entirely ruled out.
