Assessment 02 – Practical Demonstration
Practical 1: Implementing Layer 2 Security
Objectives
1. Assign the Central switch as the root bridge.
2. Secure spanning-tree parameters to prevent STP manipulation attacks.
3. Enable storm control to prevent broadcast storms.
4. Enable port security to prevent MAC address table overflow attacks.
Senario:
There have been a number of attacks on the network recently. For this reason, the network administrator has assigned you the task of configuring Layer 2 security.
For optimum performance and security, the administrator would like to ensure that the root bridge is the 3560 Central switch. To prevent against spanning-tree
manipulation attacks, the administrator wants to ensure that the STP parameters are secure. In addition, the network administrator would like to enable storm control to
prevent broadcast storms. Finally, to prevent against MAC address table overflow attacks, the network administrator has decided to configure port security to limit the
number of MAC addresses that can be learned per switch port. If the number of MAC addresses exceeds the set limit, the administrator would like for the port to be
shutdown.
All devices have been preconfigured with:
? Enable secret password: ciscoenpa55
? Console password: ciscoconpa55
? VTY line password: ciscovtypa55
Your Tasks:
Task 1: Verify Connectivity
Task 2: Create a Redundant Link Between SW-1 and SW-2
Task 3: Enable VLAN 20 as a Management VLAN

Learning Objectives
1. Enable IOS IPS.
2. Configure logging.
3. Modify an IPS signature.
4. Verify IPS.
Senario:
Your task is to configure router R1 for IPS in order to scan traffic entering the 192.168.1.0 network.
The server labeled ‘Syslog Serve’ is used to log IPS messages. You must configure the router to identify the syslog server in order to receive logging messages.
Displaying the correct time and date in syslog messages is vital when using syslog to monitor the network. Set the clock and configure timestamp service for logging
on the routers. Finally, enable IPS to produce an alert and drop ICMP echo reply packets inline.
The server and PCs have been preconfigured. The routers have also been preconfigured with the following:
? Enable password: ciscoenpa55
? Console password: ciscoconpa55
? SSH username and password: SSHadmin / ciscosshpa55
? OSPF 101
Your Tasks:
Task 1: Enable IOS IPS
Task 2: Modify the Signature

Learning Objectives
1. Verify connectivity among devices before firewall configuration.
2. Configure a zone-based policy (ZPF) firewall on router R3.
3. Verify ZPF firewall functionality using ping, SSH and a web browser.
Senario:
Zone-based policy (ZPF) firewalls are the latest development in the evolution of Cisco firewall technologies. In this activity, you configure a basic ZPF on an edge
router R3 that allows internal hosts access to external resources and blocks external hosts from accessing internal resources. You then verify firewall functionality from
internal and external hosts.
The routers have been pre-configured with the following:
? Console password: ciscoconpa55
? Password for vty lines: ciscovtypa55
? Enable password: ciscoenpa55
? Host names and IP addressing
? Local username and password: Admin / Adminpa55
? Static routing
Your Tasks:
Task 1: Verify Basic Network Connectivity
Task 2: Create the Firewall Zones on Router R3
Task 3: Define a Traffic Class and Access List
Task 4: Specify Firewall Policies
Task 5: Apply Firewall Policies
Task 6: Test Firewall Functionality from IN-ZONE to OUT-ZONE
Task 7: Test Firewall Functionality from OUT-ZONE to IN-ZONE

Learning Objectives
1. Verify connectivity among devices before firewall configuration.
2. Configure an IOS firewall with CBAC on router R3.
3. Verify CBAC functionality using ping, Telnet, and HTTP.
Senario:
Context-Based Access Control (CBAC) is used to create an IOS firewall. In this activity, you will create a basic CBAC configuration on edge router R3. R3 provides
access to resources outside of the network for hosts on the inside network. R3 blocks external hosts from accessing internal resources. After the configuration is
complete, you will verify firewall functionality from internal and external hosts.
The routers have been pre-configured with the following:
? Enable password: ciscoenpa55
? Password for console: ciscoconpa55
? Password for VTY lines: ciscosshpa55
? IP addressing
? Static routing

Learning Objectives
• Verify connectivity throughout the network.
• Configure router R1 to support a site-to-site IPsec VPN with R3.
Senario:
The network topology shows three routers. Your task is to configure routers R1 and R3 to support a site-to-site IPsec VPN when traffic flows from their respective
LANs. The IPsec VPN tunnel is from router R1 to router R3 via R2. R2 acts as a pass-through and has no knowledge of the VPN. IPsec provides secure transmission
of sensitive information over unprotected networks such as the Internet. IPsec acts at the network layer, protecting and authenticating IP packets between participating
IPsec devices (peers), such as Cisco routers.
