This training is designed for Linux professionals seeking top-tier enterprise-level certification. Internationally accredited by the Linux Professional Institute (LPI), it validates advanced competencies in cryptography, network security, access control, and system hardening.
It is offered in-person in Bogotá or live online.
Upon completing the course, participants will be able to:
- Implement cryptography and PKI systems in Linux environments
- Secure hosts through system hardening, authentication, and threat detection
- Configure advanced access control policies
- Harden networks using firewalls, IDS, and VPN technologies
- Pass the international LPIC‑3 Security certification exam
To participate in this training, attendees must meet the following requirements:
- Completion of the training programs for the International LPI-1 and LPI-2 Certifications
| Certificación internacional LPIC-3 303 Security | Applies |
|---|---|
| Certificación internacional LPIC-3 303 Security | 60 hours |
Learning Methodology
The learning methodology, regardless of the modality (in-person or remote), is based on the development of workshops or labs that lead to the construction of a project, emulating real activities in a company.
The instructor (live), a professional with extensive experience in work environments related to the topics covered, acts as a workshop leader, guiding students' practice through knowledge transfer processes, applying the concepts of the proposed syllabus to the project.
The methodology seeks that the student does not memorize, but rather understands the concepts and how they are applied in a work environment.
As a result of this work, at the end of the training the student will have gained real experience, will be prepared for work and to pass an interview, a technical test, and/or achieve higher scores on international certification exams.
Conditions to guarantee successful results:
- a. An institution that requires the application of the model through organization, logistics, and strict control over the activities to be carried out by the participants in each training session.
- b. An instructor located anywhere in the world, who has the required in-depth knowledge, expertise, experience, and outstanding values, ensuring a very high-level knowledge transfer.
- c. A committed student, with the space, time, and attention required by the training process, and the willingness to focus on understanding how concepts are applied in a work environment, and not memorizing concepts just to take an exam.
