ASSIGNMENT 4 AWARENESS OF CURRENT EVENTS Introduction: The security engineering is the environment of engineering science which deals with security and integrity of real world organizations. It also deals with system engineering in order to enforce security policies in an organization. In the modern world, the systems cut across various areas of human efforts, therefore the security engineers need not consider the substantial and logical properties of the organization. They have to concentrate on the attacks or the threats on the people of the organization utilizing the social engineering attacks. These secured systems have to defend with force, fraud and trick by confidence tricksters along with the technical attacks. They also make use of various like fault tree analysis techniques from the field of safety engineering. Roles and responsibilities of a security engineer: The main role of the network security engineer involves planning, designing, implementing, auditing, optimizing and troubleshooting network security solutions based on the customer needs. • To provide assistance in growth, implementation and safeguarding the IT security solutions like firewalls, antivirus solutions and any intrusion detection systems. • To make sure the Information and security policies. • To investigate the real time information security incidents. • To produce cyclic reports on information security issues or threats. • Before implementation of new system, he has to review the implications of security methods. • Have to give security awareness to the employees. • Has to participate in the project management tasks like tracking of projects, scheduling of the projects and final report submission. • Has to offer support for remote projects in th... ... middle of paper ... ...BIND regularly • Don’t put all DNS servers on the same sub net. • Confine the queries to minimum level Conclusion: The security issues and threats are not new and it has been around for some time. The emerging techniques help to crack it and get better solutions. Fighting against the new evolving techniques is still a hurdle and to maintain the compatibility. The specific recommendations as a security engineer is keep updating the things with regard to the security features like building firewalls and engaging with latest security happenings.

The physical security field can be broken down into two very general but separate areas: types of security and security components. The Types of Security outlines different areas or sectors where why and how security is conducted differ. Security components break down Physical Security even further, speaking to the more intricate areas of any Security type or team.
...would be best to not have a security incident happen at all, which is why details have been laid out for the prevention of such occurrences. Yet despite the best security policies, planning, and implementation, incidents will still occur, therefore CEG must have plans in place to respond. Training and planning for network security must be an ongoing routine, in order to keep pace with new threats and the evolution of existing threats.
Security architecture is a major component and part of a system’s architecture and is usually designed to provide important guidance during the development of the system. It usually outlines the assurance level required and in the process outlines the possible impacts that this level of security might have on the development process of the actual system. Since security is a major component for the success of any given business unit, it is necessary to have a fully functional and operative security system that meets all the necessary requirements for any organization. Some leading business firms are usually faced with the task of achieving and maintaining high security measures and methods. SecureTek one of the leading provider of security solutions is faced with the challenge of redesigning their security architecture to assure security to the data and the other firm’s valuable assets as well as ensuring security to their customers and employees who encounter risky situations when visiting this business unit.
Finally, we will examine the ongoing initiative on future development of information security and define how SANS Institute stays on top of the rapidly changing technology and the constant threat to information security in organizations.
Security is a wide concept, it is a separated subject with its own theories, "which focus on the process of attack and on preventing, detecting and recovering from attacks" (William 1996). Certainly, these processes should be well organized in coping with the complex system issues. A coherent approach should be taken, which builds on established security standards, procedu...
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Create a team with the following areas of expertise: Human Resources (HR), Legal, Technology, and other key business lines. The HR, Legal, and Technology team members will have a good understanding of the current policies related to information security. Moreover, such a team will be a fair representation of each area of the organization. Information Security Awareness needs to be an organizational-wide effort and must be presented in the same manner. (Wilson, M. & Hash, J,2003)
...nd organizations large and small will always need computer security professionals, the job is general secure and well-paying. I personally advise anyone that has a true interest in information technology to consider training to be a computer security specialist. It can be a very rewarding career.

...vantage of the overall network design and implement usable subnets with virtual local area networks. Use encryption and encapsulation to secure communications of public segments to enable extranets and cross-Internet company traffic. Use items such as intrusion detection systems and firewalls to keep unauthorized users out and monitor activity. Taken together, these pieces can make a secure network that is efficient, manageable, and effective.
Computer security is very essential to proyect against the threats caused to computing system which happen because of it's vulnerability. Threat to computing security takes place by a person, event or circumstance may be intentionally for sake of finance or unintentionally by deleting some of the important data. A threat agent depends on method, opportunity and motivation. Method is a knowledge to attack , oppurtinity to access the necessary information and motive behind the aatack. In olden days during 1980's and 1990's it is done for the sake of personal fame, but in 2000's it is for financial purpose to gain profits.
The human factor of physical security consists of the people who own the property being protected, the people who work at the property or those that visit the property/protected area, and the security personnel guarding the property.
Network management planning and security planning involves identifying the best and most appropriate systems and hardware that the firm can use to better manage network and plan security systems. Therefore, the management required me to examine the best software and hardware systems in the market place that the company can adopt to enable it to manage the network and security. The management required me to advice on the implementation procedure of various plans that are going to be adopted. My responsibility also involved finding out or predicting the impact of the plan on the future operations. They required me to evaluate the challenges the company might face while adopting the changes in the network management plan and security plans.
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
Their methodology must be developed around company’s culture and maturity level. As they are immature in project management, they need specific policies and procedures that dictate how to perform in the organization, which must be easy to understand and follow by executives, project managers, line managers, and line employees.
