In the age of cloud computing, traditional forensics methods are no longer enough. Businesses are increasingly storing their data in the cloud, which presents new challenges for investigators. Cloud forensics is the branch of digital forensics that focuses on the collection, preservation, and analysis of evidence from cloud environments.
Here, we explore a few tools and resources for cloud forensics investigations. Looking at the key areas of:
- Cloud forensics solutions: An overview of some of the leading cloud forensics platforms and tools available, such as Sleuthkit, Google Cloud Forensics Utils, and Cado.
- Cloud-based forensics: We will explore the advantages and disadvantages of using cloud-based forensics tools compared to traditional on-premises solutions
- Cloud forensics tools: We will compile a list of popular cloud forensics tools, categorized by their specific functions.
We've built a platform to automate incident response and forensics in AWS, Azure, and GCP you can grab a demo here. You can also download a free playbook we've written on how to respond to security incidents in the cloud.
Cloud Forensics Solutions
Google Cloud Forensics Utils is a collection of open-source tools for investigating and responding to various security incidents in Google Cloud Platform (GCP). The tools include plaso, dfVFS, and log2timeline, which can be used to collect, process, and analyze data from GCP sources.
Sleuthkit is a digital forensics toolkit that can be used to investigate a variety of devices and systems, including cloud storage. Sleuthkit includes tools for carving files, extracting metadata, and analyzing file systems.
Cado is a cloud forensics and incident response platform that helps security teams investigate and respond to security incidents in the cloud. Cado automates data collection and analysis, saving security teams time and effort. Cado also supports investigations across multiple cloud providers and environments, such as AWS, Azure, and GCP.
Cloud-Based Forensics vs. Traditional Forensics
Cloud-based forensics offers several advantages over traditional on-premises solutions. Cloud-based tools are typically more scalable and can be accessed from anywhere with an internet connection. They can also be more cost-effective, as there is no need to purchase and maintain expensive hardware.
However, there are also some challenges associated with cloud-based forensics. One challenge is that investigators may not have direct access to the underlying evidence, which can make it difficult to collect and preserve evidence. Additionally, cloud providers may have their own policies and procedures for handling legal requests, which can complicate investigations.
Cloud Forensics Tools
The specific challenges of forensics in different cloud environments, such as AWS, Azure, and GCP, vary depending on the platform's architecture and security features. However, some general tools can be used for forensics in any cloud environment.
Data collection: Cado, Google Cloud Forensics Utils, CloudTrail (AWS), Azure Activity Log (Azure), Cloud Monitoring (GCP)Data analysis: Sleuthkit, plaso, dfVFS
Incident response: Cado, Google Cloud Security Command Center (GCSCC), Azure Security Center, GCP Security Command Center
