IT teams generate vast amounts of data every second, from application logs and system logs to security logs and event logs. These digital breadcrumbs provide visibility into the inner workings of networks, applications, and systems. But with so much data coming from different sources, making sense of it all can be overwhelming.
Log management provides clarity to what could otherwise be a frustrating and impossible process. Implementing a centralized log management solution helps DevOps, IT, and security teams easily manage logs across a distributed infrastructure. Using advanced log management tools and log analytics, your team can reveal valuable insights, monitor system performance, and streamline operations from your log data.
What are the benefits of logs?
Logs are structured or unstructured data records of everything happening throughout your applications, systems, and infrastructure. Each log file contains information like:
- Application name
- Process or action type
- Log type
- Timestamp
- Host name
- Transmission Control Protocol (TCP) socket status
These logs deliver valuable insights that can help your team troubleshoot issues and trace security events. Let’s say you’re experiencing a program slowdown due to a data hack and can’t determine how it started. By following the logs, you can retrace the path that led to the issue and prevent a security incident from escalating.
While logs are incredibly useful for secure operations, the sheer volume of logs makes managing them difficult. This is where implementing effective log management, log aggregation, and structured logging becomes critical for your organization.
Why is log monitoring and management important?
Without the ability to collect, analyze, and retain log data, teams lose visibility into system behavior and risk delayed incident responses.
Key benefits of a log management solution include:
- Centralized log collection across cloud and on-prem systems
- Real-time log monitoring and alerting
- Log analysis for root cause detection
- Support for both structured and unstructured logs
- Better communication throughout different teams
- Fewer security breaches and adherence to regulatory compliance requirements
Log management gathers, sorts, and analyzes incoming logs across an entire organization’s IT landscape so you can detect patterns and monitor activity for issues in real-time. The right log management software helps you reduce noise and improve monitoring and troubleshooting throughout your infrastructure.
Log management in cybersecurity
Security and DevOps teams depend on security logs and audit logs to monitor for anomalies, quickly identify breaches, and improve security operations.
For example, a flagged login attempt may seem harmless. But, log analysis may reveal fifty login attempts from the same user happening within minutes, all from multiple different locations and IP addresses, indicating that you may be at risk of a potential hack. By leveraging log management best practices, your team can:
- Identify suspicious activity before it escalates
- Reduce mean time to detect (MTTD) and respond (MTTR)
- Maintain compliance with frameworks like PCI DSS
- Gain better transparency throughout systems
- Execute a better user experience
- Achieve increased security
Log management in cloud operations
In cloud-based operations, managing log data effectively can help detect issues like a lack of database connections or insufficient memory that may disrupt normal operations.
For example, Ulta Beauty used Sumo Logic’s cloud-native log monitoring to identify and fix a misconfiguration during Black Friday that could’ve cost the company millions in lost revenue. During a massive traffic spike, Sumo Logic dashboards identified an issue on the site allowing customers to check out with free products. Ulta Beauty was able to use their logs to trace the problem and resolve it before any severe damage was done.
With better visibility into their log data, they monitored their log file activity, optimized system performance, and improved the overall user experience during high-traffic events.
Why is managing audit logs important?
Audit logs are unalterable logs that show the historical record of business activities for compliance or policy enforcement. They can come from any part of the tech stack but must be used only for auditing purposes.
Your organization should prioritize audit log management for these reasons:
- Proves compliance with regulatory standards
- Helps distinguish between user error and system problems
- Helps identify and reconstruct fraudulent activity
- Shows weaknesses in security for future improvement
- Provides proof of actions in legal proceedings
When paired with a centralized log management solution like Sumo Logic, log files can be a powerful tool for investigating security threats and improving business operations.
