Grade "A+" Accredited by NAAC with a CGPA of 3.46
This course aims at teaching students about the fundamentals and distinctions of network building along with setup of present day networks in complex environments. The networks today are vulnerable to various attacks and the course aims at acquainting students with the techniques used by hackers for network attacks and also the techniques adopted in order to guard the entire infrastructure against varied attacks
