Design And The Technologies Used

Despite the presence of network security devices such as firewalls and other security appliances, today's corporate networks are still vulnerable to both internal and external attacks by hackers intent on creating havoc. By proactively

In conclusion, this paper discussed the popular topic of active defense and how traditional defenses aren’t very adequate anymore. Next this paper discussed honeypots used to deceive attackers. This paper also discussed Computer Network Attack and Computer Network Defense and the legal impacts between the two. Lastly this paper discussed the pros and cons of active

It is not uncommon to find various organizations complaining about security flaws in their information systems. Failing to prevent or mitigate the security flaws may lead to system breakdown, errors, and loss of crucial information. This is why it is important for users of information systems to find the right solutions that can help counter and mitigate security flaws. One common problem with security flaws connected with information systems or networks is that the security flaws occur in multiples. Technological advances have, fortunately, made it possible for people and organizations to prevent and detect such security flaws using security strategies. Layered Security and Defense in Depth are two strategies that can help prevent attacks and protect information systems against security flaws. The two strategies are similar but are based on completely two different concepts. This paper compares and contrasts the Layered Security and Defense in Depth Strategies by explaining how each of the two functions. Additionally, the paper includes an explanation about the advantages and disadvantages of the two strategies.

Defense in depth identifies the need for many security layers to be utilised in defense of the system from the bottom as physical security to the top as Data security.

This will benefit me while generating a security strategy for the Network and its hardware.

Security is almost certainly the most difficult aspect of a network to perfect. It is important to have the correct procedures and components in place to make certain network security is being accounted for and addressed on any given network. The journal, “Future Generation Computer Systems” elaborates on this necessity for an information system. “Future Generation Computer Systems”, this component of a network is discussed thoroughly. “Essentially securing an Information System (IS), involves identifying unique threats and challenges which need to be addressed by implementing the appropriate countermeasures” (Dimitrios Zissis, Dimitrios Lekkas, 2012). This was achieved through configuring access lists as well as CHAP configuration on the routers connecting to the edge

The public facing servers used to connect the internal webserver to the customer website are contained within the demilitarized zone. Due to the demilitarized zones proximity to the wide area network, we will be taking a layered security approach. There will be a statefull firewall located between the router and the demilitarized zone. This firewall will protect the internal network via the LAN-to-WAN connection by performing in-depth packet inspection and closely

5. What are the three primary methods for implementing security on this network, as well as the advantages and disadvantages each?

Defensive-preventive: has the same basic set of requirements in terms of personnel, organizational structure and costs, as an offensive-destructive strategy. A defensive-prevention strategy is necessary to protect against almost all forms of offensive strategies. All states that depend on information and cyber technologies must develop a protection strategy, either alone or in a coalition with other countries. This strategy will take years to develop and billions of dollars for implementation and support.

This memo is to identify the effective and efficient program under the Infrastructure protection plan. As the new Information Systems Security director (ISSD) protecting the basic physical asset and the organizational structure that will enable a smooth operation of the company and also the preparedness of any serious incidents that involves the infrastructure of the company is my major priority. In order to establish this strategies we need to ensure an effective, efficient program Over Long Term. And that will

I previously identified several types of attacks, threats and vulnerabilities that exist with your multilayered network. I have now been charged with the responsibility of developing a strategy to deal with these risks as well as a plan to mitigate each risk to reduce the impact that each will have on your organization.

Information security enabled by technology must include the means of lowering the impact of intentional and unintentional errors entering the system and to prevent unauthorized internally or externally accessing the system  actions to reduce risk data validation, pre-numbered forms, and reviews for duplications. It is crucial that the mission plan include the provision of a disaster recovery and business continuity plan. On the other hand, there is much more intrusion activity today than ever before. Obviously, there is an increased concern for attacks through companies’ network in an effort to either commit malice or affect the integrity of an organization’s most valuable resource. Therefore, it is important that companies do not get complacent in their IT infrastructure security. The fact of the matter, there is no perfect system; however, it behooves organizations to protect their information by way of reducing threats and vulnerabilities. Moreover, Whitman and Mattord (2010) said it best, “because of businesses and technology have become more fluid, the concept of computer security has been replaced by the concept of information security. Companies

For this OPNET simulation I proposed a network design for a small organization Job Agency that provides employment opportunities to clients based on their skill set and required job market demand. The purpose of this design is to reach the requirement of security, disaster recovery of main servers. My design introduced more redundancy by implementing a firewall for the building and further optimized the network through more application and user profile. Each of the servers was deployed service based on their application and requirements. Also I categorized the users in the entire organization as either Administrator or Employees to provide best services as per their need. Moreover, this project considers a security solution in OPNET modeler by using Firewalls as a Network access control. It consists in practical network that will explain how the Firewalls can control the ingoing and the

There have been advanced studies and research conducted to determine what best techniques and practices can be implemented by the Department of Defense to effectively protect against cyberwarfare. 3 key components have been put in place to reach this objective:

(Vacca, 2013) The idea behind this approach is to defense a system against any particular attack using several varying methods. In terms of computer network defense, defense-in-depth measures should not only prevent security breaches, they should give an organization time to detect and respond to an attack, thereby reducing and mitigating the impact of a breach. (Vacca, 2013). In a scenario where an attacker is actively attempting to gain access from the internet, a defense in depth strategy will deflect the attack, assuming that security measures like Network Address Translation (NAT), a firewall, a Demilitarized Zone (DMZ), and gateway Intrusion Detection System (IDS) are in place. Each of the aforementioned security devices provides an obstacle that an attacker must navigate; even skilled attackers who lack motivation will be deterred by a plethora of security controls. (Cleghorn, 2013). Defense in depth is an age-old military strategy. The most thought of visualization is a castle during the middle ages. The castle did not necessarily depend it wall to protect itself. It was surrounded by a moat, guard tower and bridge with a control access to the castle amongst other things. If an enemy would want to defeat this, it would have to take in to account all these defensive measures put into place. Thus, organizations like the Department of Defense use this strategy to defend its information networks. (Jones, 2005)
