Building Secure Data Systems as AWS Data Engineer Associate

This blog discusses the role of an AWS Data Engineer Associate in building secure data systems. It also discusses the key responsibilities and challenges AWS Data Engineers face in ensuring data security. Read on to learn more!

AWS Data Engineering Best Practices

Some of the most important features are listed below:

Shared Responsibility Model: Application

Customers and AWS are jointly responsible for security and compliance; clients are responsible for the guest operating system and application software, while AWS is in charge of the infrastructure. The shared approach provides flexibility and control while easing the customer’s operating burden. It determines the objectives and needs for internal and external security and compliance.

Examine each AWS service’s configuration choices and security features. Evaluate AWS Security, Identity, and Compliance services to understand how to use them to fulfill security and compliance objectives.

Authentication

This is the process of authenticating a user or machine that wishes to access a database. A variety of methods can be used to ensure secure access to vital data, including login and password authentication, multi-factor authentication, and certificate-based authentication.

Authorization

This is the process of granting access credentials to a user or system after their identification has been verified. This can include granting permission to perform certain actions, such as reading or writing data or accessing specific database objects. This helps to ensure that data is secure and that only authorized users and systems have access to it.

Encryption

This is the method of limiting unauthorized access to sensitive data stored in databases by encrypting the data in transit and at rest. AWS provides a range of encryption methods to assist in protecting sensitive data in databases, such as server-side encryption, client-side encryption, and snapshot encryption. This Data encryption technique on AWS assures that even if the database is illegally accessed, the encrypted data is secure and unreadable.

Common security threats to data systems and how to mitigate them

• Confidentiality compromise: Multifactor authorization

Multifactor Authorisation is your go-to practice to secure your data system even if your passwords and credentials are compromised. It is also another way to keep your data safe because the authentication is in your safe hands now.

• Security and Data Breach: Create secure solutions

Create strong passwords, keep your software up to date, and avoid access to too many accounts.

• Malware Attack: Keep your software up to date, install antivirus, and use foreign applications with caution.

AWS Data Engineer Associate Certification

The AWS Certified Data Engineer Associate-DEA-C01 exam validates a candidate’s ability to implement data pipelines and address performance and cost issues while adhering to AWS best practices. The certification is designed for AWS Data Engineers with 2 years of experience or more, and it is suitable for anyone in the AWS community interested in using AWS technology to transform data for analysis and actionable insights.

Role of an AWS Data Engineer

A data engineer’s primary role is to design, build, maintain, and debug an organization’s data architecture. This includes determining the best technology for a company’s needs and implementing code for any necessary customizations.

To ensure that data is prepared for analytics and reporting, build strong pipelines for data ingestion, processing, and transformation.

Utilizing open source and AWS tools, create Extract, Transform, Load (ETL) or Extract, Load, Transform (ELT) workflows to transfer data from source systems to data warehouses, data lakes, and lake houses with ease.

Security best practices you will use an AWS Data Engineer Associate

Implementing least privilege access with IAM

Use the least privilege principle. Reduce access to resources so that people can complete their duties. AWS uses identities to manage who has access to which AWS resources. IAM roles grant permissions to AWS users, services, and applications. With the help of IAM policies, data engineers can adjust access controls according to the least privilege principle. This guarantees that only those with permission can access private information or perform dangerous jobs.

Encrypting data at rest and in transit using KMS

AWS Key Management Service KMS can be used to handle cryptographic keys reliably and safely. It is simple to encrypt sensitive information while it is in transit and storage, significantly lowering the likelihood of unauthorized access. Data engineers can employ the best data protection techniques and assure compliance with industry standards by integrating KMS with other AWS services.

Ensuring secure data storage in Amazon RDS, Amazon Redshift, and AWS Secret

Redshift and Amazon RDS

both provide database encryption. They offer security features and backup options. It offers features like IAM-based access control and VPC integration to safeguard data on AWS.

AWS Secrets Manager Prevents the need to hard-code sensitive data into applications by storing and managing private data, including database credentials, API keys, and encryption keys.

Monitoring and Logging for Data Security

Monitoring and auditing data access and usage for AWS data security compliance is one of the prime roles of the AWS Data Engineer Associate.

Security and Compliance in AWS

To fulfill an array of purposes that inevitably arise in today’s environment, including security, identity, and compliance, among others, AWS has presented a comprehensive selection of services and settings. The IAM also allows for defining and applying components relating to access rules. IAM roles and policies also enable data engineers to manage the usage of the roles applying controls according to the least privilege principle. Amazon Web Services refers to AWS KMS as a secure way of creating and using keys that are used in encrypting information. AWS CloudTrail records all API activity within an AWS account.

Data Governance and Compliance

Data governance involves the ability and efforts made to regulate the accessibility, usability, integrity, and security of an organization’s data. AWS data governance strategies can be performed through Amazon S3, AWS uses Glue, and AWS Lake Formation as features and services offered by AWS. Compliance is the process of ensuring that the systems, hard and soft, as well as the data in an organization, meet certain laws, rules, and standards. To support these, AWS has several tools and services: AWS CloudTrail, AWS Config, AWS Artifact, and others.

Data Engineering Fundamentals

In data engineering, the structure that is the home for the data to be processed and kept is built and monitored. AWS Glue, Amazon Kinesis, and Amazon S3 are a few of the services that are used by data engineers to map and implement data pipelines. To ensure that their designs are fully compliant, alongside checking to make sure that all designs meet any legal requirement, rule, or standard, it is also important that data engineers consider the security and compliance aspects of their designs.

Best Practices for Data Engineering

Learn and use AWS services to develop, manage, and implement highly efficient data pipelines. Ensure all designs meet all the legislative requirements and regulations by understanding the implications for security and the matter of compliance. For data governance and compliance, invoke AWS services such as Amazon S3, AWS Glue, and AWS Lake Formation.

While it is crucial to ace the certification, Understanding the Role of an AWS Data Engineer Associate is the most important aspect of your preparation and career.
