Crypto-shredding is the method of ‘deleting’ encrypted data by destroying the encryption keys. This method is particularly useful in cloud environments where physical destruction of storage media is not feasible. By deleting the keys used to encrypt the data, the data itself becomes inaccessible and is effectively considered deleted.

Here’s how crypto-shredding works:

Encryption: Data is encrypted using cryptographic keys, which are essential for decrypting the data to make it readable.

Key Management: The keys are managed separately from the data, often in a secure key management system.

Deletion of Keys: When instructed to delete the data, instead of trying to erase the actual data, the encryption keys are deleted.

Data Inaccessibility: Without the keys, the encrypted data cannot be decrypted, rendering it unreadable and unrecoverable.

Compliance: This method helps organizations comply with data protection regulations that require secure deletion of personal data.

When dealing with a security incident in an AWS environment, it’s crucial to handle forensic evidence in a way that complies with data privacy laws. The initial step to avoid legal implications when moving data between AWS regions for analysis is to create an evidence volume from the snapshot of the compromised EC2 instances.

Snapshot Creation: Take a snapshot of the compromised EC2 instance’s EBS volume. This snapshot captures the state of the volume at a point in time and serves as forensic evidence.

Evidence Volume Creation: Create a new EBS volume from the snapshot within the same AWS region to avoid cross-regional data transfer issues.

Forensic Workstation Provisioning: Provision a forensic workstation within the same region where the evidence volume is located.

Evidence Volume Attachment: Attach the newly created evidence volume to the forensic workstation for analysis.

References:Creating an evidence volume from a snapshot is a recommended practice in AWS forensics. It ensures that the integrity of the data is maintained and that the evidence is handled in compliance with legal requirements12. This approach allows for the preservation, acquisition, and analysis of data without violating data privacy laws that may apply when transferring data across regions12.

AWS Key Management Service (KMS) keys are region-specific. An encryption key created in one region (e.g., Alabama) cannot be used to encrypt data in another region (e.g., California).

When attempting to encrypt an S3 object, the KMS key must reside in the same region as the S3 bucket. This is a limitation designed to ensure data locality and security.

Chris Noth is looking to manage user identities and automate the provisioning and de-provisioning of users in cloud-based services and applications. The IAM standard that supports this functionality is SCIM (System for Cross-domain Identity Management).

SCIM Overview: SCIM is an open standard designed to manage user identity information across different domains. It simplifies user management in cloud-based applications and services by allowing for automated user provisioning and de-provisioning1.

Automated Provisioning: With SCIM, when new users are added to an organization’s system, their identities can be automatically provisioned across various cloud services without manual intervention1.

Automated De-provisioning: Similarly, when users leave the organization or their roles change, SCIM can ensure that their access is automatically revoked or adjusted across all connected services. This reduces the risk of former employees retaining access to sensitive systems and data1.

Why Not the Others?:

XACML (eXtensible Access Control Markup Language) is used for defining access control policies, not for identity provisioning.

OpenID is an authentication standard that allows users to be authenticated by certain co-operating sites using a third-party service, without the need for passwords.

OAuth is an open standard for access delegation, commonly used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords.

For a company that provides customized software and products and has recently moved its infrastructure and applications to the cloud, the best option to help with automated integration, development, testing, and deployment in the cloud is DevOps.

Understanding DevOps: DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality1.

Automated Processes: DevOps encourages automating the software delivery process, which includes:

Continuous Integration (CI): Developers merge code changes into a central repository, after which automated builds and tests are run.

Continuous Delivery (CD): The code changes are automatically built, tested, and prepared for a release to production.

Continuous Deployment: This goes one step further than continuous delivery. Every change that passes all stages of the production pipeline is released to customers. There’s no human intervention, and only a failed test will prevent a new change to be deployed to production1.

Benefits of DevOps:

Improved Collaboration: DevOps practices encourage collaboration between development and operations teams, resulting in better communication and collaboration.

Increased Efficiency: Automation and consistency help your team do more, in less time, with significantly fewer bugs.

Faster Resolution of Problems: Continuous monitoring and automated testing mean you can identify and address bugs more quickly, often before they become a problem for users1.

Why Not the Others?:

A vulnerability assessment tool is used for identifying and assessing the vulnerabilities in a system, not for deployment.

SIEM (Security Information and Event Management) is used for real-time analysis of security alerts generated by applications and network hardware, not for deployment.

A dashboard is a type of graphical user interface that provides an overview of a system’s key performance indicators, not for deployment.
