Safeguarding Your Enterprise Data In AWS

Safeguarding your Enterprise Data in AWS
December 18, 2020

Amazon Web Services (AWS) is a popular choice for enterprises because of its robust infrastructure, scalability, high availability, and dependability. The growth in the market share is a testimony that as businesses consider moving to the cloud, AWS is their preferred choice.

However, with recent data breaches in AWS, enterprises are worried about their data safety in AWS. This paper aims to explore the security and governance in AWS.

AWS Shared Security Responsibility Model

In the cloud, safekeeping of data and workloads become a shared responsibility between the enterprise and the cloud service provider. In AWS, the service provider is responsible for the general upkeep of cloud security, while enterprises are responsible for the data they put in the cloud. This model can reduce the operational burden of enterprises in many ways and improve their default security posture.

As per the shared security responsibility model, AWS’ security responsibilities include:

  • AWS global infrastructure, which includes regional, available, and edge zones of AWS cloud infrastructure
  • AWS computation, storage, database, and networking include encryption keys, database protection, and network monitoring tools.

On the other hand, enterprises are responsible for safeguarding their data, communication, and network traffic, maintaining the cloud platform and all its aspects, and encrypting data and file systems.

Building Blocks of Security and Governance on AWS

AWS has a comprehensive security mechanism. The building blocks of security on AWS are as follows:

  1. Identity and access management (IAM) governs access permissions of resources, who can access what, and how. Services under IAM include AWS Identity and Access Management (IAM), AWS Single Sign-On (SSO), AWS Organizations, AWS Directory Service, and AWS Cognito.
  2. Continuous monitoring and logging monitors the health of software applications and hardware devices. AWS provides an end-to-end monitoring solution with services like AWS Inspector, AWS Elasticsearch, AWS CloudWatch, AWS GuardDuty, and AWS Config.
  3. Data security and encryption ensures that data is unreadable and secure. Enterprises need a key management system to ensure the keys’ high availability, durability, and security. AWS offers a Key Management Service, which includes AWS CloudHSM, AWS Key Management Service (KMS), AWS Secrets Manager, and AWS Certificate Manager (ACM) to help enterprises manage encryption and keys seamlessly.
  4. Network and edge security are vital to prevent network attacks and unauthorized access. AWS has services like AWS Web Application Firewall, AWS VPC, AWS Shield, and AWS Direct Connect to control the flow of requests through different components.
  5. Auditing governance and compliance are necessary to evaluate the security controls and ensure they adhere to regulatory guidelines. AWS services like AWS Trusted Advisor, AWS SSM, AWS CloudTrail, AWS IAM, AWS Config, and AWS Inspector help ensure compliance in the cloud.

How to ensure your data is safe in AWS

  1. Categorize and classify assets: To secure something, you must first know it exists. Many organizations fail to secure their data in the cloud because they are not aware of the type and quantity of data and the data warehouse architecture. Hackers on the lookout for such glitches can easily bypass AWS security and access enterprise data because the enterprise itself doesn’t know what exists, so they are left unsecured.
    Therefore, the first step in securing data in AWS is identifying the assets and categorizing them based on their usage. Once the assets are identified and categorized, enterprises need to classify them based on their importance and sensitivity to determine the level of security controls.
  2. Be prudent with access: Securing on-premises data is more accessible as it resides within the organization’s network parameter and has a single network connection with the outside world. However, in the cloud, the more people you give access to, the less secure your data will be. Enterprises, therefore, need to limit access to cloud-based infrastructure and protect all the parameters. Additionally, enterprises need to follow the principle of least privilege, where users are granted only the access and permissions required for their job.
  3. Use cloud-native security: While enterprises modernize their data warehouse, they often forget to do that with their security solutions. In a survey, 82% of respondents revealed that traditional security solutions either don’t work or have limited functionality. Then why are enterprises still using traditional security that doesn’t work in the cloud? The reasons vary from budget constraints to a lack of qualified staff and a lack of integration with on-premises security to ensure 360-degree security in AWS. The solution? The solution is, using cloud-native security solutions built for cloud guarantees optimal performance in the deployed environment.
  4. Keep an eye on EC2 instancesIf there is one AWS service that you need to keep an eye on to secure your data, it should be EC2. Hackers who have access to your EC2 instances can access, modify, and abuse any sensitive data within your applications. Therefore, you need to control access to EC2 based on the principle of least privilege.
  5. Define incident response policies and procedures: Most enterprises do not update their security policies and compliance after moving to the cloud. Since these policies are designed for on-premises, they do not address the security needs in the cloud. Enterprises need to update and define incident response policies and procedures to respond to cybersecurity threats in the cloud effectively.
  6. Be proactive in identifying threats: When enterprises identify attacks, the hackers already have access to the cloud infrastructure. Performing a proactive hunt to identify threats and potential incursions can help avoid breaches. To ensure proactive threat detection, enterprises need to have visibility into the cloud infrastructure and an automated threat detection system.
  7. Have visibility of controls: The enterprise IT teams should be aware of AWS’s security and data governance regulations and compliance and have end-to-end visibility of the security controls in place to make changes as required. Additionally, regulatory compliances must be revisited at regular intervals to ensure there are no loopholes in security.

With over 1800 security controls, AWS provides strong protection to ensure your data is safe in the cloud. However, organizations need a holistic security model to ensure the safekeeping of their data and analytic workloads.
