4. Lab Infrastructure

6. Equipment configuration

7. Equipment configuration (2)

8. Equipment configuration (3)

9. Access modes • The PIX firewalls (and other CISCO equipment) have four administrative access modes: • Unprivileged mode: Available at first access. Provides a restricted, limited view of system settings. (Prompt = ‘>’) • Privileged mode: Allows you to change system settings. (Prompt = ‘#’) • Configuration mode: Enables you to change system configurations. (Prompt = ‘(config)#’ • Monitor mode: Special mode that allows you to update system configuration image over the network (using a TFTP server)

10. Access modes (2) • To access privilege mode enable • To access configuration mode configure terminal • Use the exit command to exit from one mode to the previous one

11. Firewalls • System or group of systems that manage access between two networks DMZ Internet Router Firewall Outside Network Inside Network

12. PIX Firewalls • Proprietary operating system • Stateful inspection • Protocol and application inspection • User-based authentication • Virtual private networking • Web-based management • Stateful failover capabilities

13. Graphical configuration environment (PIX 501 Firewall) • Important: To access the GUI configuration environment on the PIX 501 use a PC connected to the PIX and a browser with the MICROSOFT JAVA VM enabled !! • Activate GUI environment via browser https://192.168.1.1/pdm.html

18. Viewing / Saving configurations • There are two configuration memories, running-configuration and startup-configuration • show running-config displays the current configuration in the RAM memory of the equipment. Any configuration changes are written to the running-configuration • write memorysaves the current running-configuration to the flash memory startup-configuration • show configureshows the configuration that is in flash memory • show historydisplays previously entered commands

19. Cabling description • Networking ports for each computer are numbered • Correspondence (see picture) • Move the patch cords to where you need them if they are not properly set.

20. Basic CISCO IOS commands • ip address if_name ip_address [netmask] ip address ethernet2 172.16.0.1 255.255.255.0 • show ip address • Displays the IP adresses assigned to all interfaces • show interface • allows you to view the network interface information and status • ping ip_address • To determine reachability of a system

21. Basic Windows/Linux networking commands • ipconfig (windows) / ifconfig (linux) • To obtain ip configuration information of a PC • ping • netstat –r • To obtain routing configuration and statistics • netstat • Gives you information on active ports and established connections on a system

22. Lab procedures • Lab assignments will be given a couple of days in advance to the start of the lab working period • Lab working periods = 1 or 2 weeks • Lab groups should be composed of two persons (no more, no less) • Use sign-up sheet to schedule the time in which you will be using lab equipment • Lab reports can be written in any format but should include answers to the questions presented in the assignment and equipment configuration files

23. Important recommendations • Never change a password (you’ll be held accountable) unless its for your own user account • Discharge often – get rid of static electricity build up before touching equipment • For questions: • Check CISCO web site http://www.cisco.com • Ask GSA: • E-mail: cec15@pitt.edu
