Log Management on EvrenOS

Cyber security has become a prominent field for the last decade, and many companies have spent a considerable amount of money and time to make sure their architecture is safe.

One of the approaches that many corporations use to identify malicious events in their network is to use a log management system. It involves collecting log records of events, actions, and system activities that can provide valuable insights into the health, performance, and security of an IT environment within an organization's infrastructure.  However, managing a robust log management system is a big challenge due to: 

• The variety of logs is generated from many components in endpoint devices that are hard to standardize and collect into a central log management system. 
• Plethora of log formats, parsing and normalizing log data into a consistent format for analysis can be time-consuming and complex. 
• Log integrity and privacy, verifying the integrity of log data is essential to prevent tampering or deletion of critical information. Organizations must ensure they handle log data in compliance with relevant privacy laws. 
• Performance, ensuring log management tools can handle increased data loads without sacrificing performance is a continuous challenge. 

EvrenOS solves this problem natively within the endpoint operating system that is designed to address all the challenges faced in log collection and management listed above.

Before moving into the solution, let’s try to understand what kind of log event needs to be collected from endpoint devices, there are roughly five (05) events that need to be recorded: 

1. Application events, which contain all the events from application activities within the OS, include: 
   1. Application errors and crashes 
   2. Application start and stop events 
   3. Application configuration changes 
   4. Application security events (e.g., authentication attempts, access control violations) 
   5. Application performance metrics 
   6. Application debug logs
2. System or kernel events, the logs indicate hardware detection (e.g., removable disk drives including device attachment and detachment events, device errors, and USB device information), device driver information, and kernel errors. 
3. Security events, the logs indicate user logins, session starts, session terminations, file access, and file deletion. 
4. Network events, the logs indicate network interface changes, DHCP lease information, and network configuration. 
5. Process events, the logs indicate process creation and termination, including process IDs (PIDs), parent-child relationships, and exit codes. 

Evren OS ensures that all the above-mentioned logs are generated, and parsed into machine-readable JSON format which can be consumed by any SIEM solution. 

The logs generated on Evren OS can be easily shipped to the choice of your SIEM or an S3 bucket by simply configuring the destination details on the Evren Admin Portal. 

IT admin does not need to extensively configure the endpoint to normalize the log since Evren OS already stores them in nicely parsed JSON format. 

Users also do not need to worry about scalability and performance since the feature is already embedded into the OS level, thus, not wasting any resources of the device.

The integrity of the logs is also ensured in Evren OS since every request is enforced by public key authentication.  

In conclusion, effective log management is the cornerstone of a robust and secure IT infrastructure. Organizations can gain valuable insights into their systems' performance, security, and compliance by collecting, storing, and analyzing log data from various sources.

Furthermore, Evren OS can help simplify the log management system to navigate the challenges in the fields.
