The Evolution of Digital Forensics in the Cloud

Cloud computing has become an integral part of modern business infrastructure, revolutionizing how we develop applications, broker services, and store both business and customer data. From email and social media to video streaming and web hosting, almost every service we access on the internet relies on cloud computing, making it an unconscious yet essential part of our daily operations.

The cloud’s vast data storage and computing capabilities have, however, made it an attractive target for cyber attackers. According to Check Point’s 2022 Cloud Security Report, 27% of organizations experienced a security incident in their public cloud infrastructure within the last year. In the event of a cyber incident, every minute is critical, and businesses must be prepared to respond swiftly to minimize damage.

Cloud Computing Threats

The primary motivations for cyber attackers are financial gain, hacktivism, and state-sponsored espionage. These attackers aim to seize data for sale on the black market, use ransomware to extort payments, or misuse breached infrastructure for spam, DDoS attacks, phishing campaigns, or crypto mining.

Despite its many advantages, cloud computing poses significant security challenges. Vulnerabilities often stem from identity and access management misconfigurations, a lack of understanding of cloud infrastructure, and inadequate cloud strategies and visibility. Public cloud resources are accessible by design, and improperly configured security or compromised credentials can easily be exploited by attackers.

Although cloud computing appears straightforward, it is complex and requires substantial system knowledge. Misconfigurations, excessive user privileges, and a lack of secure architecture can create vulnerabilities that attackers can exploit.

The Rise of Cloud DFIR

Cloud Digital Forensics and Incident Response (Cloud DFIR) is a specialized branch that investigates cloud resources and responds to cloud-related incidents, aiming to resolve cases more efficiently. While traditional forensics methods have been effective for decades, cloud environments require a shift in perspective, tools, and techniques.

Cloud forensics investigations can be divided into three main service models

Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Investigating virtual machines in IaaS and PaaS can be similar to traditional physical machines, requiring access to identity access logs and NetFlow logs. However, SaaS applications like Office 365, Google Workspace, Slack, Zoom, and Teams require different tools that offer comprehensive log visibility and context.

Cloud environments provide extensive data sources for investigations, primarily logs. While logs are crucial, they are not as forensically rich as data acquired directly from physical or virtual machines. Investigators need to access data from disk, memory, registry, and file systems to uncover valuable evidence.

Most cloud-related incidents also involve endpoints or on-premise devices. Effective investigations require forensic data from both cloud and on-premise environments. A unified platform for data collection, analysis, presentation, and collaboration can streamline the process and expedite investigations.

Conclusion

As enterprises increasingly adopt cloud computing, the frequency of cloud-related incidents will rise, escalating the demand for cloud forensics investigations. Implementing the right tools and adapting to new threats promptly is essential for staying ahead of cyber attackers.
