Let's now dive into the PFE (Projet de Fin d’Études) sujet and its relationship with everything

we've
discussed so far. Based on the texts you've shared, the focus appears to be on infrastructure
management, security, and monitoring in a technical and comprehensive environment. Here's how
the PFE ties into the tools and solutions we've discussed:

1. PFE Sujet Overview

The PFE Sujet (likely referring to your final project in an academic or professional setting) appears to
be focused on implementing open-source tools for managing security, monitoring, and access
control in IT infrastructures. Given your interest in using tools like Wazuh (SIEM), Teleport (access
management), and Zabbix (monitoring), the project likely revolves around:

 Designing a secure, scalable infrastructure.

 Ensuring real-time monitoring and log management.

 Integrating identity management and access controls (e.g., eliminating the need for
passwords via tools like Teleport).

 Focusing on compliance, auditability, and security best practices.

2. Relationship Between the Tools

Let’s now examine how the tools you're considering fit together and how they support the broader
goals of the PFE:

Security & Monitoring Framework

 Wazuh:

o Functionality: Wazuh, as a SIEM, will be central to log management, intrusion

detection, and compliance in your PFE. It will collect logs from various systems
(servers, devices, applications) and analyze them for security threats.

o Relevance: Security is likely a key component of your PFE, ensuring that any
vulnerabilities or breaches in the infrastructure are detected and handled in real
time. Wazuh can also serve as a backbone for audit trails, a critical feature for
ensuring that systems remain secure and compliant with standards like GDPR or SOC
2.

 Teleport:

o Functionality: Teleport provides secure access management by eliminating the use

of passwords and enforcing multi-factor authentication (MFA). It uses ephemeral
certificates for access control, which is a more secure alternative to static SSH keys
or long-lasting passwords.

o Relevance: In the context of your PFE, Teleport will be crucial for access control and
identity management. This ensures that only authorized users can access critical
systems and services, reducing the attack surface.

 Zabbix:
 o Functionality: Zabbix is a powerful tool for monitoring infrastructure, ensuring that
all components (servers, databases, applications, containers) are performing as
expected. It helps with visibility and provides alerting in case something goes wrong.

o Relevance: Your PFE will likely involve keeping track of the health and availability of
the systems you manage. Zabbix helps visualize system health, create custom alerts,
and automate responses when things go wrong, ensuring proactive incident
management.

Key Components of the PFE

Your PFE, with the tools discussed, may involve the following steps:

 Infrastructure Setup & Configuration: You’ll likely start by setting up the infrastructure,
configuring the network, servers, and any cloud resources. Integrating Zabbix to monitor
servers, network devices, and applications would be one of the first steps.

 Security and Compliance: After setting up the basic infrastructure, the next focus would be
security hardening. Using Wazuh for SIEM functionality, you’ll collect logs from monitored
systems, perform anomaly detection, and ensure compliance with standards. You may also
want to implement file integrity monitoring and security auditing.

 Access Control & Identity Management: Teleport will be integral to the security aspect,
ensuring that users have the correct access rights based on role-based access control
(RBAC). It will also simplify authentication through SSO and provide strong multi-factor
authentication methods, reducing the risks associated with traditional password-based
access.

 Incident Response & Automation: If a security or performance issue arises, Zabbix can
trigger alerts and initiate automation scripts through integrations with tools like Ansible.
Additionally, Wazuh could provide logs for deeper investigation and response.

 Integration and Orchestration: Combining Wazuh, Teleport, and Zabbix in a single

integrated environment is likely one of the core challenges of your project. Ensuring smooth
interaction between these tools would involve data sharing (e.g., alerts from Zabbix
triggering Wazuh’s SIEM for deeper analysis) and integration with other tools (e.g., Grafana
for visualization, Ansible for remediation).

Project Deliverables

 Real-Time Monitoring & Security Dashboard: A dashboard (perhaps built using Grafana)
could consolidate data from Zabbix, Wazuh, and Teleport, showing an integrated view of the
system’s performance and security status. It could highlight important metrics (e.g., CPU
load, access attempts, security incidents).

 Automation & Incident Handling: A set of automated playbooks or scripts could be

developed using Ansible (integrated with Zabbix and Wazuh) to automatically address issues
detected in the system, such as restarting services or blocking malicious access attempts.

 Compliance Reports: Generate compliance reports using the audit trails from Teleport and
Wazuh to ensure the infrastructure meets industry standards and regulatory requirements.
Conclusion & Takeaways
