Cisco IINS 1.0: Network Security Using Cisco IOS Firewalls

This course is included in our On-demand training solution.


Implementing network-wide security can be a daunting task depending on the size and business of the company. Organizations must balance the cost in staff and equipment to implement a network security policy against the potential costs of network security breaches. Cisco provides several router-based solutions for implementing firewall features: basic traffic filtering capabilities using access control lists (ACLs), Cisco IOS Firewalls, and Cisco IOS zone-based policy firewalls. This course explains the operations of the different types of firewall technologies and describes the firewall technologies that are embedded in Cisco routers and Cisco security appliances. The processes of creating static packet filters using ACLs, and configuring a Cisco IOS zone-based policy firewall on your network using the Cisco SDM wizard are also covered. This course is one of a series from the IINS 1.0 SkillSoft learning paths which cover the objectives for Cisco exam 640-553 IINS 1.0.
