What to Know About Data Security in Amazon DynamoDB?
Amazon DynamoDB is a fully managed, NoSQL database that has changed the way developers store and retrieve data. Its unique and demanding features, including scaled data handling, high performance, & seamless scalability, have made it a worthy choice, especially for large-scale businesses.
Amazon DynamoDB stands out for its ability to handle high traffic and large volumes of data with ease. But, as the volume of data increases, the risk of cyberattacks surges with it. As per stats, a data breach can cost a business an average of $4.88 million.
As the number is pretty high, there is a need to protect data at all costs. To counter this, businesses can leverage the power of Amazon DynamoDB security features like encryption, fine-grained access control, VPC integration, and continuous monitoring. Let’s read ahead and find out more about Data Security in Amazon DynamoDB.
1. Understanding DynamoDB's Shared Responsibility Model
The AWS’s Shared Responsibility Model clearly defines the security responsibilities shared between AWS and its customers.
For example, AWS is responsible for guarding the infrastructure that runs all the cloud services. This infrastructure is composed of
- Hardware
- Software
- Networking
- Physical security of data centers
On the other hand, customers are responsible for managing their data.
- Configuring encryption options
- Classifying assets
- Using IAM or Identity and Access Management tools to apply the appropriate permissions
- Setting up VPC for network security
So, when using AWZ Dynamo, you need to hire dedicated software developers to handle the data protection responsibilities.
2. Encryption at Rest in DynamoDB: How It Works
One of the best AWS DynamoDB Security features is Encryption at Rest. The database’s encryption at rest provides improved security by encrypting your data at rest using encryption keys securely stored in AWS Key Management Service (AWS KMS).
The database adds an extra layer of protection by securing your sensitive data in an encrypted table that includes
- Primary keys
- Local and global secondary indexes
- Streams
- Global tables
- Backups
3. Encryption in Transit: Securing Data Transfers
Other than data at rest, DynamoDB also ensures encryption of data in transit. Here are the ways to do it!
1. TLS (Transport Layer Security)
DynamoDB uses secure TLS protocols to encrypt data as it travels between clients, AWS services, and DynamoDB.
2. DynamoDB encryption client
The DynamoDB encryption client lets you encrypt and sign the items within the table when added to the table.
3. AWS Encryption SDK
This SDK allows you to encrypt data from the client side before sending it to DynamoDB.
4. Access Control in DynamoDB with AWS IAM
The access control in DynamoDB ensures that only authorized users and applications can access or modify data. With the AWS IAM features, you can place several access control conditions!
For example, the attribute-based access control allows you to define access permissions based on tag conditions in your identity-based policies or other AWS policies. These policies can be resource-based policies and organization IAM policies.
Furthermore, there are certain fine-grained access control features too in DynamoDB. These features enable you to grant users read and write access.
5. Fine-Grained Access Control with DynamoDB
The DynamoDB database allows you to get fine-grained access control based on the specific IAM conditions. For example,
- You can provide access permissions to users to only read certain items and attributes in a table or a secondary index.
- You can provide access permissions to specific users to only write certain items and attributes in a table.
- You can provide permissions to access the table but restrict access to specific items in that table based on certain primary key values.
Here are some keys used in DynamoDB!
- Dynamodb: LeadingKeys
- Dynamodb: Attribute
- Dynamodb: ReturnValues
6. Auditing and Monitoring DynamoDB for Security Events
Amazon DynamoDB offers state-of-the-art solutions for auditing, logging, and monitoring security events.
• CloudWatch
Collects and processes all the performance PostgreSQL development services, infrastructure, and applications. You can create customized dashboards and even set alarms that are triggered based on the performance metric.
• CloudTrail
CloudTrail keeps a log of all the API calls made to DynamoDB with specific details, such as
- The requester
- The action performed
- Timestamp
- The services used
This helps audit user activity and identify potential security issues.
7. DynamoDB Backup and Restore: Ensuring Data Integrity
- It is an on-demand backup and restore feature where you can create full backups of your DynamoDB tables’ data for data archiving. It can help you meet your corporate and governmental regulatory requirements.
- PITR is another great feature that allows you to protect your DynamoDB tables from accidental write or delete operations by creating continuous backups.
8. Protecting Against Unauthorized Access: Best Practices
DynamoDB data protection strategies include ways to prevent unauthorized access. Here are some of the best practices to include in your Amazon Dynamodb Development Services.
- Implement Strong Authentication Methods like multi-factor authentication
- Implement IAM policies
- Apply granular-level access control
- Implement client-side encryption
- Audit and monitor access controls
9. Integrating DynamoDB with AWS Key Management Service (KMS)
AWS Key Management Service (KMS) manages and gives you control over the keys used for Amazon DynamoDB Database Security. Besides securely managing keys, it also helps with the following functions!
- With AWS KMS, you can activate server-side encryption using KMS keys.
- AWS KMS helps developers more easily add encryption or digital signature functionality to their app code directly or by using the AWS SDK.
10. Common Security Threats to DynamoDB and How to Mitigate Them
The top security threats to DynamoDB are as follows!
| Threats | Mitigation Methods |
|---|---|
| DDoS attacks | Use AWS WAF and limit the read/write capacity. |
| Insider threats | Use access control and IAM policies. |
| Misconfigurations | Use AmazonConfig to detect any configuration; it can trigger notifications via Amazon SNS (Simple Notification Service) to notify the users. |

11. Compliance and Regulatory Support in Amazon DynamoDB
DynamoDB helps businesses meet industry-specific compliance and regulatory requirements by offering a fully secure environment.
With DynamoDB security features, such as encryption at rest and in transit, fine-grained access control through IAM policies, and audit logging capabilities, the database addresses regulatory compliance requirements such as GDPR and HIPAA.
It allows financial services customers to achieve industry regulatory compliances, such as SOC 1/2/3, PCI, FINMA, and ISO.
12. Best Practices for Securing DynamoDB in Production
- Use AWS CloudTrail to log all API activity
- Enable encryption at rest and transit via TLS protocol.
- Connect DynamoDB to your Amazon Virtual Private Cloud (VPC) for secure, private communication.
13. Advanced Security Features: Role of VPC Endpoints in DynamoDB
- They establish a private, secure connection between your Amazon Virtual Private Cloud (VPC) and DynamoDB without using the public internet.
- This private network reduces exposure to external threats.
- VPCs enable low-latency access.
- VPC endpoints eliminate the need to set up and maintain complex VPNs.
Conclusion
