Sobre este curso

Omitir Sobre este curso

This is a self-paced course that provides an introduction to network security topics. The curriculum focusses on how malicious users attack networks. The material is essential in later classes that will develop ethical hacking skills. Students are introduced to some key concepts in network security. Next, we provide an overview of network reconnaissance strategies.

We move on to the next stage of the network attack methodology, which is exploitation.

Next, we cover standard attack techniques, attacks such as Denial of Service, DNS attacks, and client-side attacks, and the tools used to carry out these exploitations. We conclude by focusing on the steps attackers take after they initially compromise a system.

Lamentablemente, las personas de uno o más de los siguientes países o regiones no podrán registrarse para este curso: Irán, Cuba y la región de Crimea en Ucrania. Si bien edX consiguió licencias de la Oficina de Control de Activos Extranjeros de los EE. UU. (U.S. Office of Foreign Assets Control, OFAC) para ofrecer nuestros cursos a personas en estos países y regiones, las licencias que hemos recibido no son lo suficientemente amplias como para permitirnos dictar este curso en todas las ubicaciones. edX lamenta profundamente que las sanciones estadounidenses impidan que ofrezcamos todos nuestros cursos a cualquier persona, sin importar dónde viva.
