Event Logging Policy


The purpose of this policy is to define guidelines and best practices for event logging within the scope of our SaaS (Software as a Service) at Studyo. This policy applies to all employees, contractors, and third parties with access to Studyo's systems and applications.


  1. Events (Logs): Events or logs refer to automatic records generated by Studyo's systems, applications, and infrastructures. These records include information about activities, errors, transactions, and operations performed on our SaaS services.

Objectives of Event Logging

  1. Issue Detection: Proper event logging enables us to quickly detect problems, errors, and incidents related to our SaaS services. This facilitates the troubleshooting and resolution process to improve the availability and stability of our services.

  2. Analysis and Performance Improvement: Logs play a crucial role in analyzing the performance of our services. They help identify bottlenecks, optimize performance, and make informed decisions to enhance the efficiency and quality of our offerings.

  3. Information Security: Adequate event logging contributes to information security by providing evidence of activities, helping identify attempted compromises, and enabling a swift response to security incidents.

  4. Compliance with Regulations: Log retention may be required to comply with regulations, industry standards, and legal requirements related to data protection.

Guidelines for Event Logging

  1. Logging Levels: Different logging levels should be used to classify events. We generally use the following levels:

    • DEBUG: Debugging information for developers and technicians.
    • INFO: General information about system operation.
    • WARNING: Warnings indicating potentially problematic situations.
    • ERROR: Records of errors that do not prevent the system from functioning.
    • CRITICAL: Records of severe errors that seriously affect the system.
  2. Minimization of Sensitive Information: Logs must not contain sensitive information such as passwords, credit card numbers, or personally identifiable information (PII). Ensure that such data is excluded from logs to protect user privacy.

  3. Log Storage: Logs should be securely stored in a centralized location. An appropriate retention period must be defined to meet legal and compliance requirements. Outdated or unnecessary logs should be regularly deleted.

  4. Access to Logs: Access to logs must be strictly controlled. Only authorized personnel, such as system administrators and security teams, should have access to logs.

  5. Log Integrity: Logs must be protected against unauthorized tampering. Security mechanisms such as digital signatures and read-only access should be used to ensure log integrity.

  6. Monitoring and Auditing: Regular audits of logs should be conducted to identify abnormal usage patterns, unauthorized access attempts, and other suspicious activities.


  1. Developers and Engineers: They are responsible for the correct implementation of event logging in their respective applications and services.

  2. System Administrators: They are responsible for managing, securing, and archiving logs in a centralized environment.

  3. Security Team: They must monitor logs to detect suspicious activities and respond promptly to any security incidents.

Compliance and Non-Compliance

Failure to comply with this policy may result in disciplinary action, sanctions, or legal consequences, as applicable.
