Module 4 – Network Security Essentials and Penetration Testing for SMEs (NERO)

NERO Module 4 – Network Security Essentials and Penetration Testing for SMEs provides trainees with an intensive, practical introduction to network security and basic penetration testing techniques tailored to small and medium-sized enterprises (SMEs).

The module focuses on core network security concepts, vulnerability identification, and hands-on penetration testing using industry-standard tools. Through guided exercises and real-world scenarios, trainees learn how to assess network security posture, exploit common weaknesses in a controlled environment, and recommend effective remediation strategies to improve the overall security of SME IT infrastructures.
