Log and trace management in the Nuabee DRP solution

Introduction #

Log and trace management is an essential component for the supervision and security of Cloud environments, particularly during a Disaster Recovery Plan (DRP).

Logs and traces enable system activity to be monitored, problems to be diagnosed, and compliance with security policies to be guaranteed. This document focuses on the log management solutions available in the OTC Cloud and their scope of application in the DRP space.

Importance of log and trace management #

Log and trace management offers several crucial advantages, including:

1. Supervision and Monitoring: Logs enable real-time monitoring of the status of Cloud resources, facilitating rapid detection of anomalies and failures.
2. Diagnosis and troubleshooting: In the event of an incident, detailed traces of system activity enable problems to be quickly identified and resolved.
3. Security and Compliance: Logs provide essential records for security audits and regulatory compliance, helping to prove that systems are being used in accordance with established security policies.
4. Performance Analysis: Log analysis can reveal opportunities to optimize system and application performance.

Log management solutions #

Cloud OTC offers several solutions for log and trace management, tailored to the specific needs of ARP spaces.

The Cloud Trace Service (CTS) module #

Cloud Trace Service (CTS) is an advanced solution for logging and monitoring activities in Cloud environments. It enables detailed tracing of actions carried out on Cloud resources, providing a complete, chronological view of operations. This visibility is crucial for security, incident diagnosis and regulatory compliance.

Activity log collection #

CTS collects detailed activity logs for every operation carried out in the Cloud environment. These logs include information such as :

• Operation type: Operations such as resource creation, modification or deletion.
• Timestamp: Exact date and time of each event.
• User IDs: ID of the user or service initiating the operation.
• IP addresses: source and destination IPs for tracing the origin of requests.
• Operation status: Indications of successful or unsuccessful operations, including error codes and descriptive messages.

Log storage #

Collected logs are securely stored in an S3 bucket or equivalent, with encryption measures to protect sensitive data. CTS supports configurable retention policies, enabling logs to be kept for specific durations to meet compliance requirements. These logs can be exported for in-depth analysis or auditing purposes.

Alerts and Notifications #

CTS offers real-time alert functionalities based on predefined criteria. For example, administrators can set up notifications for suspicious activities, such as repeated failed login attempts or unauthorized changes to critical configurations. These alerts can be sent via a variety of channels, including e-mail and instant messaging services.

Integration with SIEM solutions #

CTS can be integrated with SIEM (Security Information and Event Management) solutions such as Splunk or Graylog, facilitating centralized analysis and correlation of security events. This integration enables the creation of customized reports and dashboards for greater visibility of potential threats.

Cloud Log Tank Service (LTS) module #

Cloud Log Tank Service (LTS) is a robust log management solution designed to collect, store, analyze and manage logs generated within Cloud infrastructures. LTS plays a crucial role in continuous system monitoring, problem diagnosis and overall security enhancement.

Log collection #

LTS supports comprehensive log collection from a variety of sources, including :

• System logs: Logs from the operating system and core services.
• Application logs: Logs generated by deployed applications, including error messages, stack traces and debugging information.
• Network logs: Logs relating to network traffic, capturing incoming and outgoing connections, firewalls and traffic routes.
• Security logs: Include security-related events such as unauthorized access attempts, IDS/IPS alerts, and security audits.

Centralized storage #

Logs are stored centrally in an elastic storage system, often based on technologies such as S3 object storage. LTS allows you to define retention policies to keep logs according to specific business needs, ranging from a few weeks to several years.

Analysis and visualization #

LTS includes tools for analyzing and visualizing log data. Administrators can use interactive dashboards, advanced filters and search queries to explore the data.

Machine learning and anomaly detection features can also be integrated to identify unusual behavior or security incidents.

Access management and security #

LTS incorporates strict access management mechanisms, ensuring that only authorized persons can access and analyze logs. Role-based access controls (RBAC), multi-factor authentication (MFA), and encryption of data in transit and at rest are common measures implemented to protect sensitive data.

Alerting and monitoring #

Like CTS, LTS lets you configure alert rules to monitor logs in real time. Alerts can be triggered by specific events, defined thresholds, or anomaly patterns detected in logs. These alerts are crucial for proactive response to security incidents or operational problems.
