Cisco Company Vpn Case StudyEssay Preview: Cisco Company Vpn Case StudyReport this essayThe new company computer network has many challenges that need to be over come in order to provide the desired security and performance needs to assist company users. There are three locations that need to be connected together. The entire network will be connected together through a Virtual Private Network (VPN). The network connection to each site will be provided by a local internet service provider through a leased line. These leased connections will provide an always on connection ensuring the connectivity between the sites is always available, while a guaranteeing a predetermined bandwidth. The typical price for a T1 is about $1000 and provides 1.544 Mbps bandwidth. A T3 will go for $5000 while proving 44.736 Mbps of bandwidth. Taking bandwidth, price and the number of users per location, Location one will make use of a Leased T3, while location two and three will be connected using a Leased T1. If internet telephones will be used, a T3 may have be used in location three as well.
This will be a high level view of the proposed company WAN showing only the user workstation, networking equipment and WAN connectivity. There are no servers, printers and other network peripherals shown on the diagrams. There will be common equipment that will be at each location. The same model equipment will be installed in each building to increase compatibility and cost associated with training and maintenance. Security functions will be run by the Cisco ASA 5505 Security Plus appliance at each location. All Buildings within each location will be using a Cisco 2901 integrated Service router for routing needs. The Cisco 3560CG-8PC-5 switch will used to connect user workstations to the routers. Please see attachments at the end for diagrams of the network and locations.
The Cisco ASA 5505 Security plus appliance will provide firewall and VPN functions. The external network security from this unit will provided by the intrusion detection, active and passive network protection features while protecting against unauthorized network access. This model offers an always on, highly secure security services. The ASA 5505 integrates into one unit most common security functions including firewall at various OSI layers, intrusion prevention, and content security. Also integrated is VPN functionality which eliminates the need for a separate server. Combining all these functions into one unit will lower initial and maintenance costs as well as space requirements.
Within each building will be a Cisco 2901 router. This small unit will provide the routing needs for each building. It small size along with the ASA 5505 decreases the required space to store the equipment. One fain feature of this unit is its Power over Ethernet (POE) capability which when used with POE switches, greatly increases the flexibility in switch placement. The Cisco 3560CG-8PC-5 switch will be used to connect each workstation to the routing. This unit is PoE capable. The capability eliminates the need for a power source, allowing the unit to place virtually anywhere.
The ASA 5505 will provide the bulk of the system security needs mainly though the use of its VPN and Firewall features. The most economically viable method to connect all three locations together securely is through the use of Virtual Private Networks (VPN). VPNs are secure direct connection between a computer or network to another computer or network by encryption over the internet. Using VPN to connect all three locations allows the company to share private data and resources over an unsecure medium such as the internet. While VPN capabilities are available in many routers, have the capability separated from the router and paired with the firewall will decrease the strain on the router.
Samba.com offers the most detailed and useful Samba security services. You could use these services directly in your Internet or computer. For a full list of available services, please visit the full list by heading to www.sbama.com and selecting “Service”.

SSL certificate and SSL connection
By providing a certificate from your browser or a VPN, you will receive the new S/MIME type certificate which will be provided by the Certificate Authority as the public key for all web services provided by SSL.
By using SSL, you will receive a private key for the website. Simply sign up for a secure account on a web site that accepts both S/MIME and SSL and the S/MIME type certificate will automatically be generated. When you have done so, a free email or SMS message will be sent to you, which will then be sent to all internet users.
SSL certificate and SSL connection
If you are unable to use your home key with S/MIME and your home key is also insecure this service will provide you with this new certificate. However this will require you to change your personal key for web services, by clicking on the “Sign Up” button.
For more information to ensure reliable connection, please subscribe to SSL.
VPN security
The SSL VPN service offers the most complete and reliable security, security, and backup services out there.
You can find out more details about SSL VPN services at http://www.sslsoftware.com/. The services you use will be supported by SSL and not only will you get a simple and secure email or SMS message from your VPN provider.
The SSL VPN service’s default gateway will be the one that connects all three sites that your website connects to. Once in the S/MIME gateway, you will be presented with a secure email or SMS message which will be encrypted by SSL server. Once SSL has been provided, the SSL provider will take the following steps to secure the service:
Open a browser in the home/work computer. The first link in the SSL web browser will point to the site you downloaded. In case you did not already have access to the site, open a new browser then click on the “Solve Problems” link at the top right. You can save your password and have SSL continue to connect to your site. Follow the steps provided in this step guide to open this page if you need to change your password.
To change your login information in response to the SSLVPN service, you must create and sign
