Intel Defense On Depth Strategy Analysis

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.

As part of the network security team, we will be proving IDI with a network security plan to mitigate the vulnerabilities that have been discovered. A secure site will be set up with network intrusion detection and network protection systems will be available to access via the internal network. Policies will be presented for remote access and the use of VPN. Also contained within this report will be strategies for hardening the network and mitigating risks. An updated network layout with increased network security to meet the current needs will be included.

The world of cyber security continues to introduce new threats each year against network infrastructures and computer devices. In the recent years, the impact from cyber-attacks has wreaked havoc on many company brands and organizational reputations. As this issue grows so does the technology to prevent and protect against these malicious attacks. It is absolutely crucial for organizations and businesses to shift focus from defense for different types of attacks to improving safeguards to mitigate the loss of sensitive data when an attack occurs. In addition to the traditional security technology used to detect an attack, companies will have to include

In order to diminish both security and privacy risks to organizations, measures need to be taken to combat risks throughout the various stages of the threat’s life cycle. Specific processes must be implemented to identify threats, procedures to follow when the attack occurs, and finally methods to recover from the attack (Houlding, 2011).

Predicting attacks is important, but swift response is key. DHS realized that the only way to have effective incident responses is to have plenty of practice and close cooperation across government and with the private sector. To prepare for and ensure effective cooperation during a significant event, DHS instituted a cyber-attack exercise program to periodically test processes and procedures for responding to a significant cyber incident impacting the financial sector. These exercises will help clarify roles and responsibilities, identify gaps in response plans and capabilities, and assist with developing plans to address those

Incident information disclosure is an important, circuitous concern that requires acceptable centralized procedures in place to facilitate incident response processes and do not cause more harm for the organization and its audiences. Keeping information and operations secured, appropriately is of basic importance for any organization, which becomes the assignment of cyber

Security planning for any data system should always include an incident response plan. “An incident response (IR) plan is a detailed set of processes and procedures that anticipate, detect, and mitigate the effects of an unexpected event that might compromise information resources and assets” (Whitman, 2006, pg. 92). The institution of such a plan will hopefully reduce down time should any incidents occur.

Incident response begins with prevention and security awareness (figure 1). In the case of malware attacks such as viruses, worms or Trojan horses, defense-in-depth plays a large role in the defense and early detection of potential threats to information systems connected to the internet. Personnel utilizing these assets also play a large role in defending and protecting these assets. Authorized users should be aware of all policies and procedures pertaining to the proper use of all networks, applications, and systems within the organization. The

Computer security is a critical issue for nearly all businesses today. Threats to security have become more pervasive, more dangerous, and more damaging to the health of businesses. Being able to appropriately respond to a security breach is essential to the long-term success of any business. Incident response planning is necessary before an incident occurs. In their publication, Computer Security Incident Handling Guide (Special Publication 800-61, Revision 2), the National Institute of Standards and Technology (NIST) has made recommendations on the phases of incident response, what types of tools can be useful to a team responsible for incident response (IR), and what documentation is needed as part of the response. This paper discusses these topics as endorsed by NIST.

The risks that face an organization are going to always be present. However, an incident response plan outlines procedures for handling security incidents that occur within the organization and for correcting and documenting the security issue in a timely manner. The incident response team is trained to effectively implement the incident response plan. By containing an attack, and limiting the amount of time that an attack is allowed to continue, further risks to the organization can be mitigated.

In order carry out this mission DoD must have the ability to first defend its most important networks, data identify and prioritize of important networks and data to the department. This plan will allow DoD to work and operate within a disrupted and degraded cyber environment in any event that an attack on their networks. In other words, DOD strategic plan should protect its critical infrastructure and operations to improve its contingency plans in case of any attack. The idea is to build and maintain a strong security architecture and joint Information Environment to move the focus from protecting just one service-specific networks but to secure the entire DoD enterprise including agencies under the DOD. In addition, the strategic plan should have staff and personnel with the capability to mitigate all known vulnerabilities that present a high risk to the department. Also work strong layered defense by working with the counterintelligence, and whole of government agencies to defend any type of

Incident Response (IR) is “where personnel move to further identify the scope of the threat in the network and follow response procedures to contain and eradicate”. A key element in almost all incident response systems is the collection and presentation of potential incident information, more usually described as threat intelligence, which comes with two problems. First, the overall volume of data presented by incident response systems, and secondly the isolated manner in which the intelligence is reported. A common response from CISOs is that “I don’t need more intelligence, I just need better intelligence.” That “better” intelligence also needs to be “usable” intelligence by different security controls. It is of little surprise that the

Blue Moon Financial (BMF) is a large financial services firm. Recently, its information security team has been working in an elevated status to protect BMF from a recent increase in network intrusions suffered by other financial services firms. Unfortunately, even though senior management recognizes the threats posed by cyber incidents, they have not provided the senior security analyst with a high enough budget to retain experienced information security technicians; as a result, the current security team is inexperienced. Additionally, an incident response plan has not been implemented, but is currently being developed.

Day in day out, security threat is on the increase, and the need to provide adequate security for every organizations becomes more important than ever before. Of course, no one expects security attacks, but due to the way things are happening in today’s world, having a qualified team of incident handling would be of great importance. Typically, incident handling process can mean the difference between total disaster and complete recovery. For easy understanding and to avoid complications, we have simplified this article to the extent that everyone can read and understand the content.
