Use the Cisco VPN Client to test the remote access VPN. Background A comprehensive security policy covers three main areas: governing policies, end-user policies, and technical policies. Tec hnical policies can include e-mail, remote access, telephony, applic ations, and network policies , such as device access controls and logging. The focus of this lab is the creation of a technical network policy that specifies security measures to be configured for network devices and implementation of those measures. In Part 1 of this lab, you create a basic Network Device Security Guidelines document that can serve as part of a comprehensive policy. This document addresses specific router and switch security measures and describes the security requirements to be implement ed on the infrastructure equipment. The Network Device Security Guidelines doc ument is presented to your instructor for review prior to starting Part 2 of the lab. In Part 2, you build the network and configure basic devic e settings. In Parts 3 and 4, you secure rout ers and switches. In Part 5, you configure a router for VP N remote access. The Net work Devic e Security Guidelines policy is used as the guiding document. The company you are working for has two locations connected by an ISP. Router R1 represents a remote site, and R3 represents the corporate headquarters. Rout er R2 represents the ISP. Note: The router commands and output in this lab are from a Cisco 1841 with Cisco IOS Release 12. 4(20)T (Advanced IP image). The switch commands and output are from a Cisco WS-C2960-24TT-L with Cisco IOS Release 12. 2(46)SE (C2960-LA NBASEK9-M image). Other routers, switches, and Cisco IOS versions can be used. See the Router Interface Summary table at the end of the lab to determine which int erface identifiers to use based on the equipment in the lab. Depending on the router or switch model and Cisco IOS version, the commands available and output produced might vary from what is shown in this lab. Note: Make sure that the routers and switches have been erased and have no startup configurations. Instructor Note: Instructions for erasing both the switch and router are provided in the Lab Manual, located on Academy Connection in the Tools section. Required Resources      2 rout ers (Cisco 1841 with Cisco IOS Release 12.4(20)T1 Advanced IP Service or comparable) 1 rout er (Cisco 1841 with Cisco IOS Release 12.4(20)T1 IP Base or comparable) 3 switches (Cisco 2960 with Cisco IOS Release 12.2(46)SE C2960-LA NBASEK9-M image or comparable) PC-A: Windows XP, Vista, or Windows 7 with CCP 2.5, RADIUS, TFTP, and syslog servers plus PuTTY and Cisco VPN Client software available PC-B: Windows XP, Vista, or Windows 7 Page 3 of 59 All contents are Copy right © 1992–2012 Cisco Sy stems, Inc.

CCNA Security    PC-C: Windows XP, Vista, or Windows 7 with CCP 2.5, RADIUS, TFTP, and syslog servers plus PuTTY software available and SuperScan (optional) Serial and Ethernet cables as shown in the topology Rollover cables to configure the routers via the console CCP Note s:  Refer to Chp 00 Lab A for instructions on how to install and run CCP. Hardware/software recommendations for CCP include Windows XP, Vista, or Windows 7 with Java version 1.6.0_11 up to 1.6.0_21, Internet Explorer 6.0 or above and Flash Player Version 10.0.12.36 and later. If the PC on which CCP is installed is running Windows Vista or Windows 7, it may be necessary to right-click on the CCP icon or menu item, and choose Run as administrator. In order to run CCP, it may be necessary to temporarily disable antivirus programs and O/S firewalls. Make sure that all pop-up blockers are turned off in the browser.   Instructor Notes:  This lab is divided into five parts. Part 1 can be performed separately but must be performed before parts 2 through 5. Parts 2 through 5 can be performed individually or in combination with others as time permits, but should be performed sequentially. In some cases, a task assumes the configuration of certain features in a prior task. The main goal is to create the basic Net work Device Security Guidelines document and then implement the network equipment configuration using the security techniques learned in this course. For the main configuration tasks, the related course chapter is indicated so that the student can reference previous course mat erial and labs when configuring devices. This lab is written in the style of a challenge lab and does not provide many commands for the student. Students must use their memory, Cisco IOS help, or commands shown in previous labs to complete the tasks. Commands are shown in some cases where they differ signific antly from the ones used in previous labs or where the student should be familiar with the material but it was not a focus area for the course. Students present their Net work Device Security Guidelines from Part 1 to the instructor for review prior to starting lab Part 2. Make sure that they have included all elements of the sample shown in Part 1. The switches in the topology are an integral part of this lab and are secured along with the routers. The final running configs for all devices are found at the end of the lab.      All contents are Copy right © 1992–2012 Cisco Sy stems, Inc. All rights reserv ed.

Page 4 of 59 CCNA Security Part 1: Create a Basic Technical Security Policy In Part 1, you create a Network Device Security Guidelines document that can serve as part of a comprehensive network security policy. This document addresses specific router and switch security measures and describes the security requirements to be implemented on the infrastructure equipment. Task 1: Identify potential sections of a basic network security policy (Chapter 9) A network security policy should include several key sections that can address potential issues for users, network access, device access and other areas. List some key sections you think could be part of good basic security policy. Answers will vary but could include the following:             Introduction Acceptable Use Policy E-mail and Communications Activities Antivirus Policy Identity Policy Password Policy Encryption Policy Remote Access Policy Virtual Private Network (VPN) Policy Extranet Policy Device management policy Physical device security policy Task 2: Create Network Equipment Security Guidelines as a Supplement to a Basic Security Policy (Chapter 9) Step 1: Review the objectives from previous CCNA Security labs. a. b. Open each of the previous labs completed from chapters one through eight and review the objectives listed for each one. Copy the objectives to a separate document for use as a starting point. Focus mainly on those objectives that involve security practices and device configuration. Step 2: Create a Network Device Security Guidelines document for router and switch security. Create a high-level list of tasks to include for net work access and device security. This doc ument should reinforce and supplement the information pres ented in a basic Security Policy. It is based on the content of previous CCNA Security labs and on the networking devices present in the course lab topology. Note: The Network Device Security Guidelines document should be no more than two pages and is the basis for the equipment configuration in the remaining parts of the lab. Step 3: Submit the Network Device Security Guidelines to your instructor. Provide the Net work Device Security Guidelines documents to your instructor for review before starting Part 2 of the lab. You can send them as e-mail attachments or put them on removable storage media, such as a flash drive. All contents are Copy right © 1992–2012 Cisco Sy stems, Inc. All rights reserv ed.
