Task 6 Radius Server AAA

For basic authentication, AAA or the Authentication, authorization and accounting can be configured to access the local database for client logins. It will be difficult since it must be configured in every router. To take full advantage of the AAA, radius server AAA will be used. When the client attempts to login in the router, the router will show the router references to the external server database for verification that the client is using a valid username and password.

Topology for the radius Server AAA

For the Radius server AAA, you can simply configure the users and keys from host that will use for authentication.

Verify Firewall Functionality

1. Open a Telnet session from PC-C to R2 and while the session is active, run: m show ip inspect sessions

2. PC-C to PC-A would allow a ping but will refuse a telnet session.

3. PC-A to PC-C would block all traffic.

4. Syslog of PC-A logs all attempts

Task 12 CISCO Zone Based firewall

The CISCO Zone-based firewall is a new configuration model of CISCO policies for multi0interface routers. It also increases the firewall protection application and has a default auto deny all policy that hinders the traffic between firewall security zones unless the user access has been granted to allow desirable traffic to a network.

Test Firewall Functionality: from INSIDE zone to OUTSIDE zone

1. Ping from PC-C to PC-A

2. Telnet session from PC-C to R2

3. Issuing command on Router 3: show policy-map type inspect zone-pair sessions

Test Firewall Functionality: from OUTSIDE zone to INSIDE zone

1. From the PC-A server command prompt, ping PC-C.

2. From router R2, ping PC-C.

Task 13 Fortinet Unified Threat Management

Fortinet Unified threat management is a tool for security management which is used by an administrator for monitoring and managing all security-related applications and components in infrastructure in one graphic user interface console.  [7] Fortinet. (2017, October 12).

Steps on how to configure Fortinet IPS:

1. Intrusion Protection can be configured by choosing security profiles and clicking on Intrusion Protection.

Figure 13.1 Administrator can choose which signature would the allow or deny

2. Data leak prevention is another way to filter out security threats which has a sensor based scanner for an administrator to specify messages in an incoming information.

Figure 13.2 Data leak prevention in security profiles

3. VPN Tunnels are used to set up VPN connection

Figure 13.3 VPN tunnels configuration

Figure 13.4 VPN tunnel authentication

Task 14 Cyberoam Unified Threat Management

Cyberoam Unified Threat Management caters intense security to businesses from small to large companies. It has a layer 8 identity-based platform with multiple security features. It uses extensible Security Architecture or ESA to eliminate all kinds of security threats. [8] Sophos. (2017).

Minimum System Requirements:

• PC with virtual machine(Hyper-V)
• 1GB vRAM
• 2 Virtual Network Interfaces (vNIC)
• Primary Disk with 6GB size
• Auxiliary Disk with 100GB size
• 1 Serial Port
• 1 USB Port

Steps on how to configure Cyberoam UTM:

1. Download the Cyberoam installer from the website

Figure 14.1 website of Cyberoam UTM

2. Install Cyberoam Firewall on a virtual machine and be sure that the minimum system requirements are met.

Figure 14.2 login dialog box of Cyberoam

3. Run the virtual machine

.

Figure 14.3 Running virtual machine(Hyper-V)

4. On another virtual machine on the same computer (connected via VLAN), open Internet Explorer and go to http://172.16.16.16. Use admin as username and password.

Figure 14.4 login page using the designated URL

5. After logging in, the dashboard would show up displaying the status of the firewall.

Figure 14.5 Dashboard of Cyberoam UTM

6. Securing Cyberoam firewall enables user to configure appliance access thru a wizard that helps administrator setup basic Cyberoam firewall and enable user restrictions. It is based on checklists whether protocol will be enable or disable.

Figure 14.6 Appliance access of Cyberoam

7. Using Identity base policy in Cyberoam is a secured way to setup an access privilege. The user has a variety of selection based on the network’s requirement.

Figure 14.7 Identity based policy of Cyberoam

8. Using Cyberoam surfing quota will ensure that all users would comply to company’s policy. It will limit all the users on how much data was consumed at a given time period. This limit must be done by administrator.

Figure 14.8 Surfing quota of Cyberoam

9. Using Cyberoam remote VPN will enable the user to remotely connect the server to private network using VPN. It is done using web console and client outline.

Recommendation:

When implementing a secured and reliable network, it entails a lot of consideration. These considerations can be split into three main categories includes hardware, software and user requirements. The main consideration is the hardware requirements. Hardware cost is just the beginning since it needed to upgrade and maintain it regularly that could affect business network downtime and performance of the employees. These means that the company should make the best decision on what computers, firewalls to purchase. Storage is also the problem since the company is growing the data stored in the server will also increase. Lastly, the availability of the computer, since all computers are shipped from one manufacturer to the client, it will take time. Another consideration in implementation is the software requirements. First is the software legitimacy. All computers should run genuine software to prevent bugs and errors. Also, the software of all computers including the operating system must be regularly updated. Lastly, the user requirements are required for implementation. As an IT, it is our job to create a secured network environment and lessen the complex work for the end users.
