Discuss the Roles and Motivations for Separately Filtering Ingress and Egress Traffic in the Enterprise Network. Describe Separate Conditions for Both Ingress and Egress Traffic as They Transit the Network. Discuss:

An air gap is utilised to isolate a secured and non-secured network from one another to ensure security is maintained, this isolation occurs on both physical and technical levels.

! Deny any other traffic access-list 111 deny ip any any log The above commands illustrate the concept of our layer 3 design, and would need to be expanded and modified in a production environment. Let's now consider a workgroup subnet populated with desktops but no servers. Since we don't expect servers to be placed here, inbound tcp traffic is limited:

Host A will use application for the OS while allowing the PC to still communicate to other devices. Transport will control the data sent and received. The network will place IP addresses to the packets allowing data to be added to the MAC addresses and physical link between host and lines.

Information security is a business requirement and also a legal requirement, subsequently firewalls are set up as security from viruses and backups are implemented to ensure no information is lost.

”For example in a campus environment, professors working on the same project can send broadcast messages to one another without the necessity of belonging to the same department. This can reduce traffic if the multicasting capability of IP was previously used”[2]. The concept of Virtual work groups seems to be a good one in theory but in practice this does not work properly.

being filtered and the clients are more likely to receive malicious software in the form of

MAC address filtering will allow the servers to accept incoming traffic from predetermined hosts. To further secure the local area network, the network security team will be implementing the principle of least privilege in regards to the users. By using the principle of least privilege we will be preventing multiple forms of malicious or accidental risks by only giving the user the permissions and privileges necessary to complete their job. Microsoft’s default security software is commonly used and well known making the vulnerabilities well known, which would make it easier for a hacker to plan out an attack. Third party antivirus\malware and firewall software will be used on all machines. The servers located within the network will make use of a statefull firewall to monitor and filter all traffic on the network by scanning for congruence between data packets.

What services are to be permitted and denied access to your network or computer? Make a list of what enters and leaves your network. Discuss

This is an open exposure due to the uncertainties of the internet. Controlling access to information systems and associated networks is necessary for the preservation of their confidentiality, integrity, and availability. Confidentiality assures that the information is not disclosed to unauthorized persons or processes. Any automated attacks or personal attack or attack to exploit the company secrets/statistics/data is the biggest threat to that may occur without the firewall.

Why would an information systems security practitioner want to see network traffic on both internal and external network traffic?

For example, the Sales and Marketing Division has a desktop computer for each of the account representatives. All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The

The UK population is ageing noticeably, with only slow growth predicted in the adult population.

Personal identification using anthropology deals with estimation of sex, age, stature etc. by studying skeletal featured of bone. Mostly the sex estimation is finished by looking at the morphological features of Pelvis- which because of conceptive necessities shows unmistakable characteristic elements which serve as trademark; or cranium.

In this example the table shows where an employer was asked to hire more employees in order to cover 100 departments with 30 different areas. Each new employee would work in areas 1, 2, and 3. The area assigned to the employee would be determined by the employer him/herself. The table above givens an example of how it will go. Then the overall question would be how the assigned areas would be split up.

“I wanted you to see what real courage is, instead of getting the idea that courage is a man with a gun in his hand. It's when you know you're licked before you begin, but you begin anyway and see it through no matter what.” This quotation shows that to have courage isn’t always when you are be brave but when you finish something that you start. In the book “To Kill a Mockingbird” By Harper Lee,  Many characters show the trait of courage throughout the book. It also shows many important parts of the book through these quotes that are shown. In the novel To Kill a Mockingbird by Harper lee Atticus shows the trait of courage a lot in the book.  The next two quotes are ones that show that Jen is a person in the novel that shows the trait of
