7.0.1.1 Chapter 7: Access Control Lists
One of the most important skills a network administrator needs is mastery of access control lists (ACLs). ACLs provide security for a network.
Network designers use firewalls to protect networks from unauthorized use. Firewalls are hardware or software solutions that enforce network security policies. Consider a lock on a door to a room inside a building. The lock allows only authorized users with a key or access card to pass through the door. Similarly, a firewall filters unauthorized or potentially dangerous packets from entering the network.
On a Cisco router, you can configure a simple firewall that provides basic traffic filtering capabilities using ACLs. Administrators use ACLs to stop traffic or permit only specified traffic on their networks.
This chapter explains how to configure and troubleshoot standard IPv4 ACLs on a Cisco router as part of a security solution. Included are tips, considerations, recommendations, and general guidelines on how to use ACLs. In addition, this chapter includes an opportunity to develop your mastery of ACLs with a series of lessons, activities, and lab exercises.
7.0.1.2 Permit Me to Assist You
Permit Me to Assist You: scenario
Each individual in the class will record five questions they would ask a candidate who is applying for a security clearance for a network assistant position within a small- to medium-sized business. The list of questions should be listed in order of importance to selecting a good candidate for the job. The preferred answers will also be recorded.
Two interviewers from the class will be selected. The interview process will begin. Candidates will be allowed or denied the opportunity to move to the next level of questions based upon their answers to the interviewer’s questions.
Refer to the accompanying PDF for further instructions for this activity.
The entire class will then get together and discuss their observations regarding the process to permit or deny them the opportunity to continue on to the next level of interviews.Class Activity - Permit Me to Assist You Instructions
