Ethical Hacking: Linux Privilege Escalation↗

This certificate verifies that the holder has successfully completed the Linux Privilege Escalation course. The recipient has gained foundational knowledge of Linux user privilege models and learned how to identify and exploit common system misconfigurations to escalate privileges. Throughout the course, the participant practiced real-world techniques to move between users (horizontal escalation) and obtain root access (vertical escalation) on misconfigured Linux systems. Hands-on labs were used to reinforce concepts such as SUID binaries, password files, and privilege abuse methods. By completing this course, the holder has demonstrated the ability to assess Linux systems for privilege escalation vulnerabilities and apply ethical hacking techniques to gain elevated access in a controlled and legal environment. This course is designed for beginner ethical hackers and learners with basic Linux knowledge.

Basics of Database Design & Development↗

This certificate confirms that the holder has successfully completed the Database Design course. The recipient has gained a strong understanding of fundamental and advanced concepts in database design, including logical and physical data modeling, storage structures, and standard design principles. Throughout the course, the participant learned how to design efficient databases from scratch, apply normalization techniques, define constraints, and create tables, views, and stored procedures using SQL. The course also covered Entity Relationship (ER) diagrams, Relational Database Management Systems (RDBMS), NoSQL databases, and the key differences between RDBMS and NoSQL architectures. By completing this course, the holder has demonstrated the ability to design well-structured, scalable, and maintainable databases, and possesses the confidence to document database design skills in professional and academic settings. This course is suitable for learners with no prior database knowledge as well as those seeking to strengthen their database design expertise.
