New SIEM Integration with Lightrun Audit Events

Lightrun's SIEM integration enables real-time streaming of audit events to customer SIEM systems, such as Splunk. This connection allows notifications for various events, including action-related runtime events, auditable operations, user management, and configuration changes.

Security information and event management (SIEM) is a methodology for detecting, analyzing, and responding to security threats to protect business operations. It integrates security information management (SIM) and security event management (SEM) into a unified system. For more information, see SIEM Integration.

.NET Agent: Introducing the New .NET Sandbox

The Lightrun .NET Sandbox is a central component in the Lightrun .NET agent. It verifies and validates full integrity of your application’s behavior when running with Lightrun actions. The Lightrun Sandbox verifies and validates full integrity of your application’s behavior when running with Lightrun actions. The Lightrun Sandbox guarantees no exceptions, system I/O, system calls, or state/flow changes, and ensures that only read-only code is ever added to your application.

• agent_log_target_dir
• agent_log_level
• agent_log_max_file_size_mb
• agent_log_max_file_count

For more information, refer to Java, Python, Node.js and .NET documentation.

Version 1.33.0¶

Release date: 20 May, 2024 (SaaS, On-Premise to follow the next week)

HEADS UP NOTICE: Introducing Enhanced Login Method to the Lightrun Server

To align with industry standards and to streamline and simplify the user login process 
for the Lightrun Server, we have implemented a single login method. This strategy 
eliminates the cumbersome task of managing multiple methods in parallel by allowing 
administrators to set a single login method from three options: user-defined password, 
SSO, or Google.

From version 1.33, this new feature will be rolled out gradually and will 
only affect a number of selected customers.

So what's changed?

When you apply the new login method, you will need to select your preferred login method. 
Until you do that, your existing users will be unaffected and will be able to continue 
working, as usual. However, the administrator will not be able to add new users until you select your 
preferred login method.

Once the administrator selects the preferred login method, users will receive 
an activation email. Users' history will remain unaffected, and as soon as 
users reactivate, they will be able to pick up right where they left off.

Stay tuned for further instructions as we roll out these changes.

Feature Enhancements¶

.NET Agent: Concurrent Support for Additional Profiling Tools

Lightrun introduces support for profiler chaining in the .NET agent allowing you to run multiple profiling tools simultaneously on the same application or system. This feature allows developers and operators to gather performance data and insights from different profiling tools concurrently without conflicts or interference.

In practical terms, profiler chaining enables the coexistence of an additional profiling agent or tool in parallel to Lightrun’s .NET agent. For example, Lightrun's .NET agent and other Application Performance Monitoring (APM) tools, such as Datadog on the same .NET application or environment. Each profiling tool can collect specific types of performance data or provide unique insights into the application's behavior. For more information, see Profile chaining for the Lightrun .NET Lightrun agent.

Java Agent: Enhanced Log File Naming Format

In our ongoing commitment to providing administrators with enhanced control over their agents, we have standardized the log naming convention. This enhancement aims to make the convention more intuitive, facilitating easier identification and detection of your logs.

The new format is: lightrun_java_agent.<PID>.<TIMESTAMP>.<LOG_ROTATION_RUNNING_INDEX>.log

An example of the new log format: lightrun_java_agent.22840.20240513-153557.1.log In the example, The new convention includes the log name - lightrun_java_agent, the log file PID - 22840, the date and time following the YYYYMMDD-HHMMSS convention - 20240513-153557, and the log rotation running index is 1.

To facilitate the transition, here is the log convention in previous versions:

In forthcoming releases, this initiative will be extended to Node.js and .NET log files.

Java, Python, and, Node.JS Agents: PII Redaction Enhancements

• PII Redaction Now Processes Complex and Nested Objects

  In this release, we have extended the support for PII redaction to nested objects to ensure comprehensive privacy protection within complex data structures, bolstering compliance efforts and minimizing the risk of data breaches. With this update, we've tackled the challenge of masking values within multi-level objects during PII Redaction by Name.

  Please note that when PII redaction is performed on Node.JS and Python languages, the nested objects will be redacted and displayed in the log lines as REDACTED. The behavior of the Lightrun Java agent differs, as it consistently masks nested objects higher than level 1 hierarchy with
