Security Talk
On Thursday 12 of November, middle-day, at auditorium F-106, I’ll give the talk called “Seguridad hoy en dia”, where I’ll talk about issues like operating systems security, the last incidents in Linux kernel, exploitation techniques, protection mechanisms, botnets, web-apps, etc.
All are welcome.
