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 Internet RouterFirewall DMZ Inside Network Outside 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 memory saves the current running-configuration to the flash memory startup-configuration show configure shows the configuration that is in flash memory show history displays 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
