Multiple Independent Levels Of Security Architecture

A successful IT system is something that is composed of several different functional components to make it a whole. It takes each component to efficiently work so that the entire system runs smoothly. When one or more parts of the system are not properly working it can affect the entire IT system as a whole and render it completely vulnerable to people with malicious intentions. In this paper I will discuss the role of each component in it and shed some light as to why each is needed.

There are number of different models proposed as framework for information security but one of the best model is McCumber model which was designed by John McCumber. In this model the elements to be studied are organized in a cube structure, in which each axis indicates a dissimilar viewpoint of some information security issue and there are three major modules in each axis. This model with 27 little cubes all organized together looks similar like a Rubik's cube. There are three axes in the cube they are: goals desired, Information states, and measures to be taken. At the intersection of three axes you can research on all angles of an information security problem.

Layered Security refers to the use of a collection of or various tools to cover the gaps in security not covered by other tools. Layered Security operates on one principle in that there is no silver bullet when protecting networks or computers (Chatterjee, Hora, & Rosoff, 2015). This means that there is no single method of making systems 100 percent safe; instead,

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

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.

Identify the fitting application security systems which we can execute in application in every situation.

Users are assigned a unique user name and password. Passwords are required to be complex, changed frequently and will lockout after a predetermined number of invalid attempts. User sessions are required to re-authenticate after periods of inactivity. MC performs routine user account review to ensure appropriate entitlements and the removal of dormant accounts. All servers and workstations are built and hardened to the MC baseline standard with servers performing a single role (e.g. IIS). MC employs antivirus on all desktops and servers. Antivirus is centrally managed with definition updates pushed daily. MC performs routine vulnerability scans and monthly patch management. A third party external penetration test is performed annually. MC requires all sensitive data transmissions to be encrypted through web (e.g. HTTPS), bulk file transfer (e.g. Secure FTP) and email transmission (e.g. TLS) using industry recognized algorithms. Sensitive data is encrypted within the database. End users are restricted from writing to USB and CD-R. MC has deployed Security Incident Event Manager (SIEM) throughout the environment. The SIEM generates alerts which are reviewed by designated members of

Some include administrative, physical and technical safeguards. In administrative safeguards it allows the reader to understand the security management process to reduce risk and vulnerabilities. Security personnel responsible for developing and implementing security policies. Information access management minimum access to perform duties. Physical safeguard is about the limit of physical access to facilities, and how workstation and device security policies and procedure covering transfer, removal, disposal, and reuse of electronic media. Finally, technical safeguard is about the access control that restricts access to authorized personnel’s. Audit controls for hardware, software, and transitions. Integrity controls to ensure data is not altered or destroyed. Transmissions security to protect against un authorized access to data transmitted on network and via email. Moreover, there are three pillars of data security confidentiality, availability, and integrity. Confidentiality refers to the prevention of data loss, and is the category most easily identified with HIPAA privacy and security within healthcare environments. Usernames, passwords, and encryption are common measures implemented to ensure confidentiality. Availability refers to system and network accessibility, and often focuses on power loss or network connectivity outages. Integrity describes the trustworthiness and permanence of data, an assurance that the lab results or personal medical history of a patient is not modifiable by unauthorized entities or corrupted by a poorly designed process. Database best practices, data loss solutions, and data backup and archival tools are implemented to prevent data manipulation, corruption, or loss; thereby maintaining the integrity of patient

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

The major security principles are integrity, reliability and confidentiality. These three principles present a platform for establishing and applying industrial business security principles for the prevention and protection of IT structures. The three security principles are the foundation of a coherent ISMS framework as they offer a guideline for its growth.

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

Other security elements are in reference to data recovery, database administration, handling a breach in security and administrative security policies such as access procedure, employee transfer and excessive user access. As I assume the role of the chief security officer, database designer, database administrator, and chief applications designer this project is very important to the armed services and the Virgin Islands National Guard as we strive to provide global security.

The Technical safeguard provisions consist of five broad categories Access Controls, Audit Controls: Integrity Controls, Person or Entity Authentication and Transmission Security (Sayles, 2013). All of these safeguards are purposed to protect and secure sensitive data.

The purpose of this document is to provide guidelines for selecting and identifying security controls for information systems supporting the Department of Defense (DoD). These guidelines have been established to help complete a secure system within the agency. Guidelines provided in the NIST Special Publication 800-53 are relevant to all federal information systems and have been mostly established from a technical view to supplement related guidelines for national security systems.

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.
