-Understand networking fundamentals (TCP/IP, subnets, firewalls, routing). -Learn basic security concepts (vulnerabilities, attack vectors).

Para dominar os testes de penetração de rede em Segurança da Informação, é essencial obter uma sólida formação teórica por meio de cursos e certificações especializadas, como CEH, OSCP ou CISSP. Praticar regularmente em ambientes controlados, como laboratórios de cibersegurança e plataformas de simulação, permite aplicar e refinar habilidades técnicas. Estudar e compreender profundamente as ferramentas e técnicas mais utilizadas, como Metasploit e Nmap, é crucial. Manter-se atualizado com as últimas vulnerabilidades e exploits através de leituras constantes e participação em comunidades de segurança. Desenvolver habilidades de pensamento crítico e análise para interpretar resultados e identificar falhas complexas.

Building your lap is your first step to begin the practical part of learning, as you will be in a semi-real environment but without any risk of making the penetration testing on production, in network penetration testing try to have various types of operating systems like window and Linux and also virtual machines contacting firewalls form different vendors This lap will increase your confidence and ensure the effectiveness of your understanding and how each tool will work and how results will be displayed

Colaborar com outros profissionais e participar de desafios de hacking ético ajuda a aprimorar a expertise e expandir a rede profissional.

-Create a home lab with virtual machines (VMs) to simulate networks. -Use platforms like VirtualBox, VMware, TryHackMe, and Hack The Box.

Setting up a controlled lab environment is crucial for honing penetration testing skills, as it provides a safe space to practice without risking actual networks or data. Use virtual machines to emulate various operating systems and network configurations, leveraging tools like VirtualBox or VMware to create isolated environments. Aim to simulate real-world scenarios by including a variety of systems and network architectures, allowing you to experiment with penetration testing tools and techniques effectively.

Network Penetration Testing involves using tools that save time on repetitive tasks, allowing you to focus on identifying vulnerabilities. Key tools include: - Nmap: A comprehensive tool for network mapping, discovering open ports, identifying running services, and detecting common vulnerabilities. - Metasploit: A powerful framework for exploiting vulnerabilities in services and ports, escalating privileges, gaining persistent access, and clearing traces. - Wireshark: A network protocol analyzer that helps examine network traffic to identify sensitive information and detect malicious activity.

Becoming familiar with the tools you utilize will make your career significantly easier. I find that taking notes on the steps it takes to properly replicate using a tool can save you a lot of time when your memory is dim on that topic. Setting up labs in VirtualBox or Hypervisor and conducting experiments is the most efficient way to deepen your understanding of your toolbox. Given the multitude of tools in the infosec industry, it can be overwhelming to feel the need to learn them all at once. My advice is to focus on mastering one tool at a time to maximize efficiency. Once you can confidently explain how it works to others, it is best to explore more software.

-Get proficient with essential tools like Nmap, Wireshark, Metasploit, Burp Suite, and Nessus. -Regularly practice with these tools in your lab environment.

-Study common penetration testing methodologies such as OSSTMM, NIST SP800-115, and PTES. -Understand phases like reconnaissance, scanning, exploitation, and reporting.

Understanding penetration testing methodologies is essential for systematic testing. Frameworks such as the Open Source Security Testing Methodology Manual (OSSTMM) and the Penetration Testing Execution Standard (PTES) provide comprehensive guidelines, covering planning, reconnaissance, exploitation, and reporting. Adhering to these frameworks ensures thorough, ethical tests and prevents critical steps from being overlooked.

-Engage in real-world scenarios and capture-the-flag (CTF) challenges. -Participate in penetration testing competitions and exercises.

Gaining real-world experience through practicing various penetration testing scenarios is crucial. Use your lab to simulate different network environments and potential attack vectors, challenging yourself with scenarios that require creative solutions to security problems. This hands-on practice will enhance your technical skills and develop the critical thinking necessary for successful penetration testing.

- Engage in Capture the Flag (CTF) competitions to enhance your problem-solving and hacking skills. - Work on Hack The Box machines to gain hands-on experience with real-world scenarios. - Utilize TryHackMe for interactive learning and practical cybersecurity exercises. - Develop and test your skills by setting up and practicing in your own home labs, creating and implementing various security scenarios.

-Stay updated with the latest security trends and vulnerabilities. -Follow cybersecurity blogs, forums, and subscribe to relevant newsletters. -Obtain certifications like OSCP, CEH, and CISSP for formal recognition.
