Private IP Address
The use of a private IP address on a business computer network has a number of advantages, one being an improved network security as well as a corporate social responsibility of conserving public addressing space. These IP addresses are commonly used on local networks and are good for businesses that share data as well as voice information.
The company's computer network will not connect to the internet with this local network connection. Likewise, computers out of the network will be unable to connect directly to a device with a private IP. This is will adequately solve the issue of lack of IP addresses in a public network such as the internet as well as provide the company the flexibility of creating enough IP addresses. According to Cisco Systems (2004),there are numerous networks that exist alongside public ones and it is not just practical to use any IP address. Therefore,…...

Kris Corporation's parent domain (kris.local) and child domain (corp.kris.local) for the organization's AD infrastructure are running on Server 2008. The following are concerns related to AD: (1) Kris Corporation is concerned about running multiple domains, and (2) automobile manufacturers are asking Kris Corporation to use a single identity to procure orders in real time. The company has five locations in Atlanta (GA), Baltimore (MD), Chicago (IL), Seattle (WA) and San Diego (CA). The manufacturing plants are in Atlanta and Seattle. Disaster recovery is a big concern. Physical space for servers is an issue at the Atlanta location. Most of the IT staff is in Atlanta, which is the company's headquarters, but other locations have significant IT personnel as well. Business personnel are similarly distributed across the company's locations. Since all locations are independently connected to the internet, file sharing is difficult among sites.

TCP/IP Protocol Suite
For the average computer user, TCP/IP probably doesn't mean a whole lot, except maybe when it comes to "configuring" their computer so they can get online, but without the TCP/IP protocol, the activity experienced on the Internet up until this point would not be possible. This paper will examine some of the components of the TCP/IP protocol and explore their uses as they apply to relevant parts of the Internet.
TCP/IP is the acronym for Transmission Control Protocol/Internet Protocol, which was originally established by the Department of Defense in 1993 to connect defense department computers with other computer networks. This network grew to include government and educational institution computers and eventually it has grown to include the widespread use of commercial and private networks.1
Simply put, TCP/IP "allows cooperating computers to share resources across a network." 2 Developed by Department of Defense researchers, TCP/IP once revolved around that ARPAnet.2…...
Next, firewalls capable of blocking IP addresses need to be installed and used (Becker, Clement, 2006). The focus on these efforts is just the first phase; there needs to be a monthly audit of IP addresses in the departments where P2P file sharing has occurred to make sure it isn't happening again. This an be accomplished using a series of constraint-based configuration tools that will trap on P2P known client footprints or digital signatures and immediately block them (Hosein, Tsiavos, Whitley, 2003). This technology will also work to isolate any inside IP addresses which attempt to reach P2P client-based download sites and immediately log and block all IP activity for the address. This will make a given IP address inoperable and immediately delete it, which will make any subsequent hacking attempts of the system useless. This is precisely the strategy the U.S. Government is using today to ensure a…...

After server authorization four domains for giving and registration of addresses of clients are created. "If a physical LAN has more than one logical subnet, how can different groups of clients be allocated addresses on different subnets?
One way to do this is to preconfigure each client with information about what group it belongs to. A DHCP feature designed for this is the user class option. To do this, the client software must allow the user class option to be preconfigured and the server software must support its use to control which pool a client's address is allocated from. (DHCP FAQ (http://www.dhcp-handbook.com/dhcp_faq.html#iaplh)
In order to create domain, wizard is used. In nets 208.32.16.0, 208.32.16.64, 208.32.16.128 elimination range is used only from one (last) address of range, because it's assigned to router's port as it was mentioned above.

This allows access to the WAN resources over the Internet. It entails secure access to HHSC resources applying encryption. This enhances the security by regulating the protocols that the workstations can access. It has regulatory access to the applications to which the employee is not authorized. (DI Wide Area Network (WAN) Operations) Each of the TCP/IP network requires a unique IP address. An IP address is a 32-bit number that specifically identifies a network interface on a machine. The IP address constitutes some decimal digits.
It is formatted in forms of four 8-bit fields demarcated by periods. Such form of representations of IP address is sometimes referred to dotted decimal format. The IP address is dived into two categories -- the network part and the host part. The network part indicates the specified number assigned to the specific network. This also assists in identifying the class of the network assigned.…...

In today's world, the Computer has become a common feature in any organization anywhere in the world. This may be due to the fact that a computer can be accessed by anybody who knows how to handle it and also because it can store a lot of information both confidential and general. A computer is connected through a physical network that allows a person or many persons to share any information necessary.

This is why computer evidence -- such as the email itself -- cannot outweigh the underlying crime. What is being investigated is a threat against human life.
While investigating this threatening email and Westfall (the main suspect), it is important for the investigator to heed the law; suspects still have all the legal rights and protections afforded them per the United States Constitution (eyes & Brittson 2007). "eading emails, intercepting communication, searching and copying computer data may land you in hot water if you do not have the proper permissions, or authority to do so" (2007). All investigations including computer crimes must follow certain forensic procedures in order for evidence to be admissible as well as to avoid civil and criminal liability.

The internet has rapidly grown and expanded. Its expansion and progress is unstoppable as the rate of growth recently has been increasing tremendously. With a few keystrokes one is able to visit an online library, bookstore, newsstands, and connect with family and friends. Nowadays searching for a website or email is like visiting a library. As is the case with physical addresses, the internet to uses addresses to locate specific devices found online. "The addresses can either be 32 or 128 bit number, which is referred to as Internet Protocol (IP) addresses" Graham, 2001, p. 35.

IPv4 versus IPv6
The explosive growth in the number of devices that are connected to the Internet has placed enormous pressures on the system's infrastructure. The current Internet protocol addressing system is projected to be inadequate to handle the increased number of telecommunications devices that are expected to be in use in the coming years, and engineers have taken steps to accommodate these increases in use through a new protocol known as IPv6.* This paper provides an overview and history of IPv4 and IPv6 and a comparison of the two technologies, followed by a summary of the research in the conclusion.
What is IPv4?
According to IPv4 (2005), "IPv4 is version 4 of the Internet Protocol (IP). It was the first version of the Internet Protocol to be widely deployed, and forms the basis for most of the current Internet"; the IPv4 protocol was first described in Internet Engineering Task Force equest for…...

Senior leadership of a medical center has just recently reviewed the plan for changes to the center's facilities. However, the medical center found out that the associated risks related to the new and emerging technologies had not been addressed. Thus, the Hospital's Chief Operating Officer (COO) has given a Chief Information Security Officer (CISO) two weeks to deliver a quick evaluation of the risks as well as the planned expansion of the areas that may pose potential technology problems.
Security Issue at the Medical Center
The main security issue at the Medical Center is the protection of patient's identity and keeping patient's data anonymous as much as possible. In the contemporary IT environment, protection of the emerging technologies has become a challenge for many organizations since sophisticated hackers could used different strategies to steal patient's information from the central database, which include Social Security Number (SSN), credit card numbers, bank…...

Enhanced Network Security with Access Control Lists (ACLs)
In the corporate landscape, network security is paramount to protect sensitive data, maintain business continuity, and comply with industry regulations. Access Control Lists (ACLs) serve as a crucial defense mechanism by implementing fine-grained access controls, enhancing overall network security.
Concept of ACLs
An ACL is a set of rules that define who can access specific resources within a network. These rules are applied to network devices such as routers, switches, and firewalls to regulate network traffic based on criteria like source IP address, destination IP address, port number, and protocol.
