Dev-Sec
A practical ethical-hacking study log: Linux commands, web vulnerabilities, and hands-on experiments that leave the terminal pleasantly busy.
Hey am Dawit ECE dropout and learning CS on the weekends this is a channel where I post what I learn and this channel specifically focuses on Ethical Hacking nothin else :)
Dev-Sec documents the road from fundamentals to practical web security. The channel teaches Linux and networking, breaks down HTTP and access control, and shares experiments such as brute-forcing a locally hosted DVWA with Burp Suite. Along the way, a 95-day challenge keeps the learning moving, while Planflow turns that progress into a small productivity web app.
Dev-Sec learns by turning each topic into a compact lesson, usually with commands, examples, and a security angle. They pair fundamentals such as Linux and HTTP with practice in DVWA, Burp Suite, and structured challenges, then adjust the plan when a platform or room is unavailable.
