Observability 101: The Critical Role of Logs in Modern Cybersecurity
Introduction
In the intricate world of cybersecurity, understanding and utilizing logs is not just a practice but a necessity. These detailed records, or 'security event logs', serve as the cornerstone for an effective security incident and event management (SIEM). This blog will delve deeper into the technical aspects of security telemetry, exploring the key sources of security data and examining how Observo.ai leverages AI in its observability pipelines to transform security operations centers (SoCs).
The Technical Nuances of Logs in Security
Logs, in essence, are chronological records that document the events occurring within an organization's IT infrastructure. Their analysis is fundamental in identifying patterns indicative of cybersecurity threats or operational issues. This practice forms the core of observability in cybersecurity, where the focus is not just on what is happening, but also on understanding the 'why' behind these events.
Diving into the Data Sources of Security Telemetry
- Operating System (OS) Logs: These logs provide a granular view of the events at the OS level, including system calls, user actions, and system errors. Analyzing these logs helps in detecting anomalies like unauthorized access or malicious activities.
- Firewall Logs: Critical for network security, firewall logs record attempts to breach network security protocols. They offer insights into traffic patterns, allowing for the identification of potential external threats.
- Content Delivery Network (CDN) Logs: CDN logs are vital in a distributed network environment, providing data on access requests, resource usage, and potential DDoS attacks.
- Active Directory (AD) Logs: AD logs in Windows environments are central to understanding user behavior and role-based access control, crucial for detecting privilege escalations and lateral movements within the network.
- Identity and Access Management (IAM) Logs: IAM logs offer insights into user authentication and authorization processes, helping in identifying unauthorized access attempts and ensuring compliance with access policies.
- Cloud Infrastructure Logs: These logs provide visibility into operations within cloud environments, including access logs for storage services, network traffic logs, and virtual machine activity logs.
- Networking Device Logs: Logs from networking devices like routers and switches are pivotal in monitoring data flow, spotting traffic anomalies, and identifying potential internal network breaches.
- Kubernetes Logs: In containerized environments, Kubernetes logs give insights into container deployments, operations, and inter-container communications, vital for securing microservices architectures.
- VMWare Logs: For organizations relying on virtualization, VMWare logs provide data on virtual machine activities, helping in the detection of anomalies and ensuring the integrity of the virtualized environment.
- Other: Additional sources like application logs, database logs, and third-party service logs also contribute significantly to the security telemetry.
