Network Security
CCNA Security
Admission open
Device hardening, AAA, ACLs, zone-based and ASA firewalls, IPS and site-to-site VPNs: entry-level network security skills for people who already know CCNA networking.
About this course
Today's organisations are challenged with responding rapidly to emerging network security threats. Security personnel configure and monitor threat mitigation measures, such as device hardening, intrusion prevention systems and firewalls, to protect data assets and network systems from attack. This course provides skills and knowledge in the field of network security.
Learners are exposed to the foundational knowledge required to respond to network security threats through various threat mitigation measures.
