Security Engineering Model

During SDLC phase one, the initiation phase, “the need for a system is expressed and the purpose of the system is documented” (NIST, 2008). Some of the expected outcomes from this phase would be a project plan and schedule; system performance specifications outlining the operational requirements, system design documents, and a document that defines roles and responsibilities. The corresponding RMF step, security categorization, establishes the foundation for security standardization among information systems and provides a vital step towards integrating security into the information system (NIST, 2008). During this step, the type(s) of information processed by the information system are identified and the information system is categorized to determine the level of protection requirements to put in place. Some of the expected outputs of this step include a security project plan and schedule, documented system boundary, the system categorization, and the security roles and responsibilities. These two process steps are very similar except the focus of RMF is on information security related functions. In some cases, SDLC produces the expected outputs that RMF requires, and the security professionals only require a copy of the documentation for their records. For example, the system design document often depicts the system boundary. The reason this step is so critical is that it

| The security controls for the information system should be documented in the security plan. The security controls implementation must align with the corporate objectives and information security architecture. The security architecture provides a resource to allocate security controls. The selected security controls for the IS must be defined and

One of the important part of system administration should be secure, so it is very important to understand which factors can affect security inside and outside our system. There are many key decisions that have to be made, for example, what server operating system should a system use to which

Since the system/application domain involves business’s mission-critical systems and applications, as well as data, it is important to ensure security of this domain. Failure to do so can result in a large loss of information and can ultimately lead to the cease of productions. This will ensure the protection of confidential data and its integrity. By implementing monitoring software tools, this will analyze any potential vulnerability that may exist on the

This paper serves to direct the development team along a pathway of security, with the intent to share information about the most secured manner to implement this project. It must first be acknowledged that for information to be secured, information security must be integrated into the SDLC from system inception. The early integration of security in the

The security and authorization family controls are focused on the creation and maintenance of a security plan. Through this it would identify the individuals responsible for information systems and the development of plans and how to implement them by creating goals to help them in meeting their overall goal for their security program.

As such, he introduces a technique of identifying a spectrum of potential vulnerabilities and suggests procedures to deal with them. Systems Specification and High Order Language Implementation are categorized as items of high risk to attacks. Security Policy and Machine Language Implementation are classified as items of moderate risk of being vulnerable to attacks. Circuits Electronics and Device Physics are of low and very low risks respectively. He also discusses potential threats such as deceiving operating systems to grant access to file or data to unauthorized users through direct (overt) and indirect (convert) channels. Walker also says that lack of precise definition of trusted operating systems and the higher cost of building them are the significant drawbacks faced by the vendors. Vendors are concerned that if they build trusted operating systems, they might not be accepted by their customers. The only solution suggested by the author was to have someone or a company builds it, shares the technology used, and convinces the general public on the significance of it. Once it becomes accepted, then there will be a widespread use of trusted computer operating systems.

While this is a daunting task, by breaking these controls down into larger groups the basis for policies and procedures are outlined and framed. The key areas that must be met initially are the establishment of a system security plan that describes we are implementing as well as the security control requirements for the

The “STG” protocol started in the Florida Department of corrections in 1992 it made a huge effort to identify the levels of gangs in the prison population. There had been significant numbers of disruptive incidents and attributes to the gang activity with trends and increase of younger inmates in the Florida corrections facility. The STG are considered “two or more inmates acting together who pose a threat to the security or safety of staff and disruptive to the orderly management of the system”. What the Security Threat Group ‘STG” management initiative was the result of “blue prints” of gang activity in Florida. What Security Threat Intelligence Unit (STIU) is the national leader in STG identification, process, and assessments of gangs? The primary focus is for

Preventive controls can be as simple as locks and keys to access sensitive areas of a building, clearances to access classified data, or the use of complex passwords with encryption. Detective controls can be as simple as cameras or motion detector systems in a building, or, as complex as a network intrusion detection system (NIDS) on the network. Corrective controls, usually combined with preventive and detective controls, help reduce the damage once a risk has manifested. This can be done by performing regular backups in the event of a system crash. Below is an illustration (Figure 4-1) of the three main types of security

Members of the Emergency Management Team or Team Coordinators will instruct all individuals to evacuate at Rally Point “X” located behind the church through word of mouth.

You did a good job with the creation of your ruff daft for your threat model process flow diagram and threat model process description document.IT appears from both these document you have a excellent base for the creation of your final product. However, I do have a couple of recommendations which I hope will be able to help you in the creation of your final product. My first recommendation is for the steps of your threat model process. Though you have some very important steps which are need for an threat model process, it may be necessary to add a few more steps for better clarity and more guidance on how to perform your threat model process. To do this you might want to go back and look at the week one instructions. In these instruction the professor provided several steps which are commonly used in thereat modeling processes. These steps included:

Miller Inc. which is in the business of providing data collection and analytics services relies majorly on network security to keep its competitive advantage. This is because the customers that rely on the company's system trust that since there are sufficient security measures that have been ensured, they can store their data securely. Each of the functional models of the system should have sufficient security measures to ensure that complete security of the whole system architecture is achieved. The three functional modules are the backend module, services or operation module and customer access module. The major relationship between infrastructure and security comes in the role they play to ensure that the end user gets the data that they need when they need it and in the best way possible. Therefore for the three modules, there is a need to balance security with the right infrastructure.

Among civilian communication systems, vehicular communications emerge as one of the most convincing effort made to enhance safety and improve the efficiency of transportation systems, to meet ever-increasing traffic demands. Security is one of the critical factors that need to be addressed towards the deployment of vehicular communication systems. The efficiency of the transportation systems, as well as the physical safety of vehicles, drivers, and passengers depend on the security factor. Vehicular communications has to pass through the analysis of potential security threats and the design of a robust security architecture able to cope with these threats. In this paper we deal with the security threats and security architecture design.

In SDLC, information security is not considered from the inception of the project from the investigation phase, in contrast, SecSDLC implements information security in each stage of the phases. Implementation of security as an integral part of the development process helps to avoid vulnerabilities in the system and integration of security at each stage of the phases will be a seamless operation and the amount of spending and time requirement will be significantly minimized. Another key difference which makes the SecSDLC more attractive over SDLC is the fact that SecSDLC attempts to analyze existing security policies and find loopholes in the system, examine legal issues and perform risk assessment of the current threat to the IT infrastructure at hand and based on the assessment results buildup of security blueprint and incident response planning will be performed (Whitman & Mathord, 2012, p.26-28). This stream-lined process makes the SecSDLC more suitable for current IT Systems where threats and vulnerabilities are limitless. Systems designed with no inherent security blueprint in place such as the traditional SDLCs fail to survive in the current and future IT systems. In the current and future IT implementation, prevention is given more emphasis than finding a cure once exposed to threats and
