The Ethernet switches will guarantee a LAN connection and will be configured to achieve the highest availability. At the New York and Satellite branches, one device with be connected to the Internet through either A Digital Subscriber Line (DSL) modem while the second device is connected through a private link to ensure a redundant network connection and avoid outages (Glass, 2004). The connections from the branches to the headquarters will be through the use of a private or leased line. This connection will require two IPSec tunnels that permanent connect to the two branch offices. In the tunnel mode, IP packets will be protected between gateways and will encrypt traffic (Firewall.cx, 2015). It is recommended that have two IPSec tunnels to each branch location to ensure a secure connection. The internet connectivity will be over the broadband Internet
The establishment if further broken down for the Regular Army, since each active duty post is authorized a VPN concentrator; however, approval for the VPN concentrator still must be granted by the Army Network Command before deployment (Army, 2007). In receiving approval, the Army Network Command is better able to maintain change management, ensuring changes such as the addition of a VPN concentrator, is documented, planned and tested in the future. Regarding the end user’s workstation, and to assure users are not inadvertently opening a backdoor, the client workstation must be configured according to the following guidelines. First, the client workstation must meet the accreditation standards set by the installations Network Operations Center to include the standards established by AR 25-2. Secondly, split tunneling is not allowed to be turned on at the client workstation (Army, 2007). Lastly, workstations belonging to high-value targets, generally high ranking individuals, or those working on sensitive projects, will have a host based IDS
Nature has always been one of the toughest obstacles. It always has its way of bringing out the crazy side of people. It can test a boy’s potential, authority, and dedication. In Doris Lessing’s “Through the Tunnel,” the main character, Jerry, refuses to give up on getting through the tunnel. Instead, he is determined to prove that he will not be labeled as a little kid. He will not pay attention to the signs that he is not old enough to get through the tunnel without getting hurt. As a result, he sets out to prove that he can win this battle and that he is not a little boy anymore. The setting in “Through the Tunnel” has an impact on the characters, the plot, and symbolism.
“Through the Tunnel”, written in the early 50’s by Doris Lessing, is a short story filled with literary devices that create a coming of age story. On the surface, the story is about a boy named Jerry, an eleven-year-old boy, who is being raised by his widowed mother. They are on vacation on a beach at their usual annual spot. Jerry is faced with a challenge he desperately wants to overcome, by any means necessary. Doris Lessing uses symbolism and bildungsroman to portray the theme of coming of age.
As a business grows, an organization often expands to multiple offices across the country and even around the world. In order to expand and keep things running smoothly, the new offices need to have a fast and secure network to share information across computer networks. In addition, traveling employees like consultants and sales representatives need an equally secure and reliable way to connect to their business's computer network from remote locations. Fortunately, VPN (virtual private network) is one of the popular technologies to accomplish these goals. According to Tyson and Crawford, a VPN is a private network that uses the Internet to connect remote sites or users together. By using a VPN, an organization ensures security that non-authenticated user can intercept the encrypted data. This article will discuss about the advantages and disadvantages when VPN comes to its security and design to a higher level of secure communication when compared to other remote methods of communications, the cost to set up VPNs within an organization, and the scalability and flexibility in terms of growing with the company and adding new users to the network.
To establish the IPSec tunnel, Fabrikam uses a third-party firewall appliance. The IPSec tunnel uses a shared secret password for authentication of the tunnel endpoints.
TCP/IP hijacking- Through the use of IPSec or a similar encryption method, you can eliminate instances of TCP/IP hijacking on your network. This incident occurs when an unauthorized user has knowledge of a legitimate IP address on the network, performs a DoS attack to remove the connection, and the spoofs the known address as their own to establish connection with another authorized user on the network.
There is no physical connection between the two buildings occupied by the organisation. The school is already sharing information through a VPN site to site tunnel. The current VPN approach throughout the school is not efficient. There is currently a disaster recovery opportunity in place of school data.
IPsec or IP Security is a merit protocol used to deliver secure data connection. The motive of the paper is to introduce VPN and IPsec with different VPN over IPsec applications.
They assume that the underlying infrastructure, which is mainly based on whether IPv4 or IPv6 is also possible to classify the different mechanisms. At the beginning of ran out of IPv4, IPv6 access gradually began adding even though IPv4 networks, providers are beginning to consider the deployment of IPv6 networks only. This change of policy is still IPv4 supports only the necessary means to allow users to access the network, the IPv6 networks only. Several mechanisms have been proposed and more are currently being discussed at the IETF. The following is a description of the mechanisms of the most widely deployed and more mature.
I choose the devices needed for the new implementation: Cisco Catalyst 6500 router and 2800 series four switches will be utilized. Here is the cost of effective access switches that are capable of VLAN, DTP, DHCP, RSTP, PoE, and furthermore, price can range from $1,400-$3,500 dollars each. These switches offer integrated security including network control and quality service, they also offer redundancy to provide and deliver intelligent services for a networking edge. Therefore, they include flexibility in the routing series as increased port density which could induce a rapid growth in networks without any additional cost at any time. However, the more capacity a device may have the more beneficial it will be to the administrator user, when setting up any secure measures throughout the configuration process of vlans and networks. The network accessibility will be ensured throughout the provision of redundancy of routers throughout the xACME network on each site or trade school. Although, optic fiber cables will be used to connect all layer 2 and 3 switches and servers, spanning tree protocol will be set on switched to address to eliminate any bridging loops from entering into any
