ทำงานเป็น QA อยู่ในทีมที่ต้องทำงานเกี่ยวกับเรื่อง Authentication , Authorization
หลายครั้งที่รู้สึกว่าฟังคำศัพท์ของ Secuirty ไม่รู้เรื่องเลยว่าตอนนี้คนในทีมกำลังพูดคุยอะไรกัน
เลยเป็นที่มาให้มาลงเรียนหัวข้อนี้กับทาง IBM ผ่านทาง Coursera
หลังเรียนจบ คลังคำศัพท์เกี่ยวกับ Security เพิ่มมากขึ้น รู้จัก Tools ต่างๆเพิ่มมากขึ้น ถือว่าคุ้มค่าที่มาลงเรียน
หวังว่าความรู้ที่ได้เรียนไปแล้วสามารถนำมาประยุกต์กับงาน QA ได้ดียิ่งขึ้น
ขอขอบคุณ IBM มา ณ ที่นี้ด้วยครับ
Working as a QA in a team dealing with Authentication and Authorization, I often found myself lost when listening to discussions about security terms. I barely understood what my teammates were talking about, which led me to enroll in this course with IBM through Coursera.
After completing the course, my vocabulary in security has significantly expanded, and I’ve gained knowledge about various tools. It was definitely worth taking this course. I hope the knowledge I’ve gained can be effectively applied to improve my QA work.
A big thank you to IBM for this amazing learning opportunity!
