Task 2 Exchange Server
Exchange server is a Microsoft product for messaging system that includes mail server, email client and groupware application. It is mainly design for companies for the employees to share information easily via taking advantage of Outlook server such that the company’s calendar and contact lists are always in sync. Minimum requirement for the exchange server is as follows: 64-Bit processor, 512GB RAM, 64GB disk space and an ethernet adapter. [2] Microsoft. (2017).

Configuring Mailbox Roles
In this setup, we are going to configure the Exchange server to perform multiple in order for our users to send and receive emails. We need to include the following: (1) Hub transport – responsible for routing messages (2) Client Access – offers all available protocol access to mailboxes (3) Mailbox – this contains the mailboxes and public folders. We need these three roles for the Exchange Management Console to make the necessary changes.
- Open Exchange Management Console and choose Organization Configuration on the left pane. Select your server and click New Mailbox Database on the right.

Task 5 Site-to-site VPN
Using VPN for the router in CISCO network provides more secured connection of transmitting data over public network. It can reduce the overpriced costs of leased lines. For the site-to-site VPNs it will provide a tunnel using IPsec between two branches of offices. Another use of site to site VPN is the remote access for the client and server for small offices.

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.

Verification
In the running configuration, the router will connect to the radius server for verification in the login console oof the router.
Using telnet, the client computer could connect to the router using RADIUS authentication.
Task 7 TACACS + Server AAA
TACACS or the Terminal Access Controller Access-Control System Plus is a protocol from CISCO systems and was released I 1993. TACACS+ don’t implements transmission control. Compared to the Radius, which encrypts only the user’s password as it travels from one client to another client. All other information in Radius will be able to see so it is vulnerable compared to TACACS+. In TACACS+, it encrypts all information including all other information traveling in the network.

Task 8 Vulnerability Assessment using GFI Languard
GFI Languard is used for scanning network security and patching management solution. It provides a complete platform of your network setup, risk analysis and maintains a secure and compliant network. This process includes scanning the network to discover all your devices connected in the network including mobile devices and search for security issues. All devices can be managed either by performing remotely with agent or none. For a remote agentless scan, specify first your target devices scanning profile that indicates what to look for, enter proper authorizations. [5] GFI. (n.d.).
Steps on how to setup and use GFI Languard:
1. Alerting Options of GFI Languard can be found by logging to the console.
Figure 8.1 Alerting option configuration
- Setup an email address where the alert will be coming from and also specify a recipient.
Figure 8.2 General setup for email addresses
- Next is the vulnerability assessment settings. It will provide an option which profile will be scanned and activate high security vulnerabilities.
Figure 8.3 Profile options for vulnerability assessment
- The profiles selected can be edited so that administrators can add and remove different items that would be included or excluded on the scan.
Figure 8.4 Vulnerabilities profiles
Figure 8.5 Each profile can be further customized to best fit the requirement of the organization.
Figure 8.6 Scanning options for network and software audit
- Scheduling a scan for GFI Languard makes vulnerability scanning an easy for administrators. It offers a Scheduled Scan option to perform scan at specific date and time.

Task 9 NVD – National Vulnerability Database
NVD is the U.S. government source of standards from NIST – National Institute of Standards and Technology based on vulnerability management data characterized using the Security Content Automation Protocol (SCAP). The data from NVD enables automation of security administration, vulnerability dimension, and acquiescence. NVD includes database of checklists in security and software flaws, malfunctions, merchandise names, and impact metrics. [6] NVD. (2017, October).
