\subsubsection{USER}\label{user}

I am a project supporter for a trainee which is working on his final
project.\\
The project studies the implementation and evaluation of the open source
security solution, \href{https://documentation.wazuh.com/}{Wazuh}.\\
\textbf{Study the documentation via a Web Search before answering.}

The project has to be completed in a time span of two weeks (10 work
days).

For our hardware base we have a computer with 32 GB of RAM and a strong
enough CPU.\\
Outline the project planning; this is a template for the project
goals:\\
1. Implement Wazuh in a test environment. The base infrastructure has to
be build and prepared. (Which OS?, Infrastructure scheme for the Wazuh
agent, manager and alerting systems)\\
2. Implementation of penetration tests and potential attack scenarios
(brute-force-attacks, port-scanning and exploits and weaknesses)\\
3. Analysis of Wazuh's reaction. (Real time monitoring and alerting,
automatic defense mechanisms, Logging and Reporting)\\
4. Optimization of Wazuh and Security policies.\\
5. Piratical importance and use in the industry

Think about the time scheduling and difficulties in the project.

\subsubsection{ASSISTANT}\label{assistant}

Okay, let's map out a project plan for your trainee's Wazuh final
project. Considering the two-week (10 workdays) timeframe, a Proxmox
base, and the scope you're outlining, we need to be realistic and
prioritize. This outline balances project goals with achievable
milestones within the time constraint. I'll provide a detailed schedule
with estimated time commitments and potential pitfalls.

\textbf{Overall Strategy:} We're going to aim for a \emph{functional}
implementation with a strong foundation for further exploration. We
won't necessarily cover \emph{every} feature of Wazuh in detail, but we
will demonstrate core functionality and build a platform for the trainee
to learn more. Documenting each step thoroughly is crucial, not just for
the project itself, but also for the trainee's learning.

\textbf{1. Infrastructure \& Base Build (Days 1-2 -- High Priority)}

\begin{itemize}
\tightlist
\item
  \textbf{Operating System Choice:} Ubuntu Server 22.04 LTS is a solid
  choice. It's widely supported, has excellent Wazuh compatibility, and
  is familiar to many Linux users. Debian is also excellent, but
  Ubuntu's larger community and readily available resources often make
  troubleshooting easier.
\item
  \textbf{Proxmox VM Configuration:}

  \begin{itemize}
  \tightlist
  \item
    \textbf{Manager VM:} Minimum 4GB RAM (6-8GB is better for future
    expansion), 2 vCPUs. Allocate enough disk space (50GB+) for logs and
    Wazuh data.
  \item
    \textbf{Agent VM (at least 2-3 for testing):} 2GB RAM is typically
    sufficient. Allocate 20-30GB of disk space.
  \end{itemize}
\item
  \textbf{Infrastructure Scheme:}

  \begin{itemize}
  \tightlist
  \item
    \textbf{Manager (Centralized):} This VM hosts the Wazuh manager
    components: \texttt{wazuh-manager}, \texttt{wazuh-logtest},
    \texttt{wazuh-api}, and database (Elasticsearch is standard).
  \item
    \textbf{Agents (Distributed):} These VMs are the targets of Wazuh
    monitoring. They run the \texttt{wazuh-agent} process. Ideally,
    these should represent different ``typical'' workloads: a web
    server, a database server (if possible), and maybe a desktop
    environment.
  \item
    \textbf{Alerting:} We'll leverage Wazuh's built-in alerting
    mechanism (email, Syslog). We're not setting up a dedicated external
    SIEM in this timeframe.
  \end{itemize}
\item
  \textbf{Task Breakdown (Days 1-2):}

  \begin{itemize}
  \tightlist
  \item
    \textbf{Day 1:} Proxmox setup, Manager VM creation \& basic
    configuration (network, hostname, time).
  \item
    \textbf{Day 1.5:} Agent VM creation (at least 2, more if time
    allows).
  \item
    \textbf{Day 2:} Install and configure Wazuh Manager components on
    the Manager VM. Initial agent deployment. \emph{Key: Get at least
    one agent reporting successfully to the manager.}
  \end{itemize}
\end{itemize}

\textbf{2. Penetration Tests \& Attack Scenarios (Days 3-5 -- Medium
Priority)}

\begin{itemize}
\tightlist
\item
  \textbf{Focus on Fundamentals:} Don't try to do everything. Pick 2-3
  realistic scenarios that demonstrate Wazuh's capabilities.

  \begin{itemize}
  \tightlist
  \item
    \textbf{Scenario 1: Brute-Force SSH:} Simple to execute,
    demonstrates authentication monitoring.
  \item
    \textbf{Scenario 2: Port Scanning (Nmap):} Demonstrates detection of
    reconnaissance activity. Make sure the firewall rules don't block
    the manager, so Wazuh can detect the scan.
  \item
    \textbf{Scenario 3: Exploiting a Vulnerable Service (e.g.,
    vulnerable web server):} Requires more setup but showcases
    vulnerability detection (if Wazuh's rules are configured to cover
    it, otherwise the goal is to show Wazuh detection and alerting of
    unexpected service activity).
  \end{itemize}
\item
  \textbf{Tools:} Nmap, Hydra (for brute-force), Metasploit (optional
  for more complex exploits).
\item
  \textbf{Task Breakdown (Days 3-5):}

  \begin{itemize}
  \tightlist
  \item
    \textbf{Day 3:} Set up basic penetration testing environment (tools
    installation, initial configuration). Execute SSH brute-force attack
    against an agent.
  \item
    \textbf{Day 4:} Execute port scanning against agents. Begin initial
    configuration of Wazuh rules (if time allows, focus on SSH
    brute-force and port scanning detection).
  \item
    \textbf{Day 5:} Execute the vulnerable service exploit (if chosen).
    Focus on observing Wazuh's reactions.
  \end{itemize}
\end{itemize}

\textbf{3. Analysis of Wazuh Reaction (Days 5-7 -- High Priority)}

\begin{itemize}
\tightlist
\item
  \textbf{Focus:} Real-time monitoring, alerting effectiveness, log
  analysis, and reporting.
\item
  \textbf{Metrics:} Time to detection, accuracy of alerts, frequency of
  false positives.
\item
  \textbf{Tools:} Wazuh dashboard, log files, command-line tools (grep,
  less).
\item
  \textbf{Task Breakdown (Days 5-7):}

  \begin{itemize}
  \tightlist
  \item
    \textbf{Days 5-6:} Review Wazuh dashboards and logs in real-time
    during and after the penetration tests. Analyze the alerts
    generated.
  \item
    \textbf{Day 7:} Generate a basic Wazuh report (daily/weekly summary
    of detected events).
  \end{itemize}
\end{itemize}

\textbf{4. Optimization of Wazuh and Security Policies (Days 8-9 --
Medium Priority)}

\begin{itemize}
\tightlist
\item
  \textbf{Goal:} Reduce false positives, improve detection accuracy, and
  tailor Wazuh to the specific environment.
\item
  \textbf{Tasks:} Fine-tune Wazuh rules, adjust thresholds, exclude
  specific events from monitoring (carefully).
\item
  \textbf{Considerations:} This is iterative. Expect to make adjustments
  based on observations from the analysis phase.
\item
  \textbf{Task Breakdown (Days 8-9):} Review Wazuh's documentation on
  rule customization and exclusion. Adjust rules as needed.
\end{itemize}

\textbf{5. Practical Importance \& Use in the Industry (Day 10 -- Low
Priority/Presentation Prep)}

\begin{itemize}
\tightlist
\item
  \textbf{Research:} Briefly research how Wazuh is used in different
  industries (security vendors, cloud providers, etc.).
\item
  \textbf{Presentation:} Prepare a short presentation summarizing the
  project's findings, demonstrating Wazuh's capabilities, and discussing
  its potential benefits.
\end{itemize}

\textbf{Potential Difficulties \& Mitigation:}

\begin{itemize}
\tightlist
\item
  \textbf{Time Constraints:} Prioritize core functionality. Don't try to
  cover everything.
\item
  \textbf{Wazuh Complexity:} The initial setup can be challenging. Start
  with the basics and gradually add complexity.
\item
  \textbf{False Positives:} Expected. Requires time and effort to
  mitigate. Emphasize the iterative nature of rule tuning.
\item
  \textbf{Proxmox Knowledge:} Ensure the trainee has basic familiarity
  with Proxmox.
\item
  \textbf{Dependency Conflicts:} Occasionally, packages can conflict. Be
  prepared to troubleshoot.
\end{itemize}

\textbf{Important Notes for the Trainee:}

\begin{itemize}
\tightlist
\item
  \textbf{Documentation:} Document every step, including successes and
  failures. This is critical for learning.
\item
  \textbf{Ask Questions:} Don't hesitate to ask for help.
\item
  \textbf{Focus on Understanding:} The goal is to understand how Wazuh
  works, not just to get it working.
\item
  \textbf{Have Fun!}
\end{itemize}

To help me refine this plan further, could you tell me:

\begin{itemize}
\tightlist
\item
  What's the trainee's current level of Linux experience?
\item
  Has the trainee worked with Proxmox before?
\item
  Are there any specific security concepts or vulnerabilities the
  project should focus on?
\end{itemize}

\subsubsection{USER}\label{user-1}

Write a summary - potentially visual/graphical - which shows the
structure of the chosen setup: proxmox host with several VMs for the
different purposes with taking into account network settings, user
settings and other necessary information.

Too answer your questions:\\
- The trainee's Linux experience is medium. But he has beginner
knowledge in using the command line as he's doing a course by
\url{https://tryhackme.com/login}\\
- The trainee has not worked with promxox before, but I would help him
to setup it up.\\
- The project should focus on security concept important in industry
environments which are usually internal networks.

\subsubsection{ASSISTANT}\label{assistant-1}

Okay, let's create a visual summary of the proposed setup, tailored to
the trainee's experience and the focus on internal network security.
I'll present this as a layered description that you can translate into a
diagram (using tools like draw.io, Lucidchart, or even just hand-drawn).
I'll then follow this with considerations for user accounts and
networking.

\textbf{1. Visual Summary - Layered Diagram Description}

\emph{(Imagine this as a diagram with layers. We'll describe each layer.
I'm using text to represent visual elements; you or the trainee would
translate this into an actual visual representation).}

\textbf{Layer 3: Physical Hardware (Base)}

\begin{itemize}
\tightlist
\item
  \textbf{Element:} A box labeled ``Proxmox Host Server''

  \begin{itemize}
  \tightlist
  \item
    \textbf{Attributes:} ``32GB RAM'', ``Strong CPU'', ``Sufficient
    Storage''
  \item
    \textbf{Connection:} This is the base of the diagram.
  \end{itemize}
\end{itemize}

\textbf{Layer 2: Virtual Machines (VMs)}

\begin{itemize}
\tightlist
\item
  \textbf{Elements:} Three distinct boxes positioned above the Proxmox
  Host:

  \begin{itemize}
  \tightlist
  \item
    \textbf{VM1: ``Wazuh Manager''}

    \begin{itemize}
    \tightlist
    \item
      \textbf{Attributes:} ``4GB RAM (6-8GB Recommended)'', ``2 vCPUs'',
      ``50GB+ Disk''
    \item
      \textbf{Operating System:} Ubuntu Server 22.04 LTS
    \item
      \textbf{Services:} \texttt{wazuh-manager}, \texttt{wazuh-logtest},
      \texttt{wazuh-api}, Elasticsearch (for Wazuh data)
    \end{itemize}
  \item
    \textbf{VM2: ``Agent 1 -- Web Server''}

    \begin{itemize}
    \tightlist
    \item
      \textbf{Attributes:} ``2GB RAM'', ``1 vCPU'', ``30GB Disk''
    \item
      \textbf{Operating System:} Ubuntu Server 22.04 LTS (or a
      simplified web server OS like Alpine Linux for minimal attack
      surface -- if appropriate for the trainee's skill level)
    \item
      \textbf{Services:} Apache/Nginx (minimal web server setup),
      \texttt{wazuh-agent}
    \end{itemize}
  \item
    \textbf{VM3: ``Agent 2 -- Database Server''} (Optional -- if time
    allows and the trainee is comfortable)

    \begin{itemize}
    \tightlist
    \item
      \textbf{Attributes:} ``2GB RAM'', ``1 vCPU'', ``30GB Disk''
    \item
      \textbf{Operating System:} Ubuntu Server 22.04 LTS
    \item
      \textbf{Services:} MySQL/PostgreSQL (minimal database setup),
      \texttt{wazuh-agent}
    \end{itemize}
  \end{itemize}
\item
  \textbf{Connections:} Arrows pointing \emph{upward} from the Proxmox
  Host to each VM, indicating virtualization.
\end{itemize}

\textbf{Layer 1: Logical Network (Overlay)}

\begin{itemize}
\tightlist
\item
  \textbf{Element:} A dotted-line box encompassing all three VMs,
  labeled ``Internal Network (192.168.1.0/24)'' -- This is a simplified
  private network.
\item
  \textbf{IP Addresses (Example):}

  \begin{itemize}
  \tightlist
  \item
    Proxmox Host (Management Interface): 192.168.1.10
  \item
    Wazuh Manager: 192.168.1.11
  \item
    Agent 1 (Web Server): 192.168.1.12
  \item
    Agent 2 (Database Server): 192.168.1.13
  \end{itemize}
\item
  \textbf{Firewall:} \emph{Crucially}, a simplified representation of a
  firewall within the Proxmox Host or on the network itself. This
  highlights the need for controlled access.
\end{itemize}

\textbf{2. User Accounts \& Security}

\begin{itemize}
\tightlist
\item
  \textbf{Proxmox Host:}

  \begin{itemize}
  \tightlist
  \item
    Create a dedicated user account for the trainee (e.g.,
    \texttt{wazuh-trainee}). Restrict access to the minimum necessary
    for managing the VMs.
  \item
    Enable 2FA (Two-Factor Authentication) for all Proxmox accounts.
  \end{itemize}
\item
  \textbf{Wazuh Manager VM:}

  \begin{itemize}
  \tightlist
  \item
    Create a dedicated user for the Wazuh manager (e.g.,
    \texttt{wazuh}). Restrict privileges.
  \item
    \emph{Important:} Configure SSH access to the manager \emph{only}
    with key-based authentication. Disable password authentication.
  \end{itemize}
\item
  \textbf{Agent VMs:}

  \begin{itemize}
  \tightlist
  \item
    Create a dedicated user for each agent (e.g., \texttt{webuser},
    \texttt{dbuser}).
  \item
    Restrict user privileges. Use \texttt{sudo} for necessary
    administrative tasks.
  \item
    Disable direct SSH access to the agents if possible (use
    \texttt{wazuh-agent} for remote management).
  \end{itemize}
\end{itemize}

\textbf{3. Network Considerations}

\begin{itemize}
\tightlist
\item
  \textbf{Private Network:} Use a private IP address range (e.g.,
  192.168.1.0/24, 10.0.0.0/24).
\item
  \textbf{DHCP:} Consider a DHCP server for simplified IP assignment.
\item
  \textbf{DNS:} Set up a basic DNS server (even just a local one) for
  name resolution.
\item
  \textbf{Firewall Rules:} (This is vital for a secure internal network)

  \begin{itemize}
  \tightlist
  \item
    Allow traffic \emph{between} the VMs necessary for Wazuh monitoring
    and agent communication.
  \item
    Restrict external access to the VMs. For example, only allow SSH
    access to the Wazuh Manager from the Proxmox Host.
  \end{itemize}
\end{itemize}

\textbf{Important Notes for the Trainee \& You:}

\begin{itemize}
\tightlist
\item
  \textbf{Documentation is Key:} Document \emph{everything} -- VM
  creation, configuration, network settings, user accounts.
\item
  \textbf{Security Best Practices:} Reinforce security best practices
  throughout the setup process.
\item
  \textbf{Gradual Complexity:} Start with the basics and gradually add
  complexity as the trainee gains experience.
\item
  \textbf{Focus on the ``Why'':} Explain \emph{why} certain
  configurations are necessary for security.
\item
  \textbf{Testing:} Thoroughly test the setup after each configuration
  change.
\end{itemize}

To tailor this further, could you clarify:

\begin{itemize}
\tightlist
\item
  What level of detail should the trainee document? (e.g., full command
  output, just configuration files)
\item
  Do you want the trainee to focus on specific security concepts (e.g.,
  least privilege, defense in depth)?
\end{itemize}
