Cloud Changed Everything About Threat Detection — Here’s What it Means For You
Admin Apr 24, 2023
The unmatched flexibility and scalability of the cloud makes migration a no-brainer for many organizations.
But often, a holdover reliance on legacy security tools and on-prem processes hinders resilient cloud environments. A security strategy that isn’t cloud-specific has clear consequences: Most security incidents now involve the cloud.
Whether you’ve already completed your cloud migration or you’re somewhere in the process, it’s critical to optimize security through cloud-tailored threat detection, investigation, and response (TDIR) and cloud-native tools. This significantly eases the burden on IT and security teams, and it’s key to achieving high integrity, user experience, and confidentiality standards.
Here’s what makes TDIR in the cloud different — and how an integrated SecOps model paired with services expertise ensures a sustainable cloud security program.
How cloud changed the game for TDIR
The systems, technologies, and processes that comprise the cloud environment are fundamentally different from on-prem systems, and this results in unique security parameters. In multi-cloud environments, nuanced but critical differences in the way security is handled by various vendors make ongoing collaboration essential.
Further, optimizing security for cloud infrastructure requires newer, richer telemetry sources like cloud audit logs, as well as cloud-native detection tools, platforms, and methods. These adjustments streamline IT workloads and reduce operational overheads for team members executing TDIR.
Beyond the infrastructure itself, the cloud-based threat landscape also differs significantly from that of on-prem systems. As cloud footprints grow, organizations’ attack surfaces and security risks also increase. Misconfigurations, unstructured identity and access management (IAM), data leakage, and more can expose organizations to serious threats and require rigorous oversight. And because many cloud services are owned by other teams, all elements of security strategy must be consistent.
But adjusting your security strategy for the cloud is worth it. By making these changes, you allow teams to reimagine paradigms for resilient systems, and strengthened end-user and customer protections. This is possible through an integrated SecOps model powered by the Google Cloud Platform (GCP).
The integrated SecOps model in 3 steps
Google Cloud Security offers a full SecOps suite for maximizing your TDIR process. Leverage this suite through a three-step approach that enables informed security decision-making and rapid incident intervention.
1. Detect with Security Command Center (SCC) Premium: As GCP’s native risk and security tool, the SCC enables real-time visibility into cloud misconfigurations, security vulnerabilities, and overall asset health. As a managed service, premium threat detection through the SCC identifies cloud risks and eases the burden for your SecOps team.
2. Investigate with Chronicle SIEM: After the SCC surfaces security alerts and events in your cloud environment, Chronicle SIEM thoroughly investigates sophisticated threats and analyzes cloud-based risks. By normalizing and synthesizing cloud and security telemetry, this tool provides rapid analysis of suspicious activity.
3. Respond with Chronicle SOAR: As the final step, SOAR ensures timely incident response to system alerts and malicious events. This tool relies on playbook automation to contextualize threats, then combines case management, cross-team collaboration, and integrated threat intelligence to facilitate appropriate remediation sequences.
