This nugget walks through the process of configuring your router to support Cisco SDM and using the SDM to perform a security audit or one-step lockdown of your device.

Video 5 - "Foundation Router Security: Implementing Secure Router Management" - One of the first areas of security you should consider is the management traffic between you and the network devices. In this nugget, Jeremy describes creating an Out Of Band (OOB) management network and three areas of network management: syslog, SNMP, and SSH.

Video 6 - "Foundation Router Security: Understanding and Implementing AAA" - AAA is more than just roadside assistance; it represents authentication, authorization, and accounting (AAA) methods you can use on a Cisco device. This nugget describes the concepts behind AAA and walks through the setup of a AAA device and the Cisco ACS TACACS+ server.

Video 7 - "Foundation Router Security: Using IOS-based Tools for Administrative Access" - While server security is essential, network security is of the utmost importance. One of the first network areas requiring more security is the area of administrative access. By default Cisco switches and routers will allow someone to attempt to logon to the device infinitely. This nugget focuses on locking down this logon prompt, configuring role-based access (sub-administrators), and securing the IOS and configuration files on your devices.

Video 8 - "Foundation Router Security: Becoming an ACL Wizard" - Understanding the implementation of Access Control Lists (ACLs) is critical for any Cisco environment, however, you can apply ACLs in more ways than one. In this nugget, Jeremy walks through guidelines for using ACLs followed by four practical scenarios of ACL implementation.

Video 9 - "Foundation Switch Security: Locking Down the Catalyst Switch" - In this nugget, all eyes turn to the internal network as Jeremy discusses Layer 2 security for your network.
