- Vulnerability assessment and penetration testing concepts.

- Malware analysis concepts, techniques, and reverse engineering.

- In-depth knowledge of network and host security technologies and products (such as firewalls, network IDS, scanners) and continuously improve these skills.

- Security monitoring technologies, such as WAF, Web Proxies, UEBA, DLP, among others.

- Strong understanding of MITRE ATT&CK framework, cyber threat landscapes, attack vectors and threat actors.
