Need For Security Policy
A security policy is defined as “The framework within which an organization establishes needed levels of information security to achieve the desired confidentially goals”
The main aim of a security policy is to update users, staff and managers of their mandatory requirements for protecting technology and information assets of their company. The policy must clearly specify the ways through which these requirements can be met. Another purpose of security policy is to provide a standard from which they should acquire, configure and audit computer systems and networks for compliance with the policy. Hence an attempt to use a set of security tools in the absence of at least an implied security policy is meaningless.
It also defines what should be done when the user misuses the network, if there is any attack on the network or if there are any natural outage to the network.
How Security Policy is formed?
The above diagrams gives a detailed explanation of how an effective security policy can be formed.
People responsible for forming a security policy.
For a security policy to be applicable and operational, it requires the acceptance and support of all levels of employees within the organization. The support of corporate management is crucial for the security policy process, or else there is little chance that they will have the wished-for impact. Below is the list of the people who must be involved in creation of security policy documents.
1. Site security administrator.
2. Information technology technical staff (e.g., staff from computing center)
3. Administrators of large user groups within the organization (e.g., business divisions, computer science department within a university, etc.)
4. Security inc...

...to be viable for the long term, it requires a lot of flexibility based upon an architectural security concept. A security policy should be (largely) independent from specific hardware and software situations (as specific systems tend to be replaced or moved overnight). The mechanisms for updating the policy should be clearly spelled out. This includes the process, the people involved, and the people who must sign-off on the changes.

Final Assignment Topic 1: What are the capabilities and limitations of intelligence in supporting homeland security efforts? The United States has endured numerous security breaches and high security threats over the past two decades. After the attacks on 9/11, the office of Intelligence became a vital source in retrieving sensitive data and tracking down potential terrorists and their networks which could pose a threat to the American people and then forwarding that vital information to the Department of Homeland Security and other government agencies.
Network Security is the protection of the computer’s network though out the entire infrastructure. It can protect very important information and computer files to help prevent theft, spyware, malware, viruses, and more. Depending on if you have a public or private network, can determine what type of security settings you need for your network. All people are different on what they want to have secured or not, but most people do not know how to prevent people or things from getting in their network. “You must have a general understanding of security terminology and specifications as it relates to configuring hardware and software systems.”(Roberts, Richard M. 599). That quote states that by knowing and understanding security terms and specifics, you can
The recent horrific attacks on France highlighted one of the number one threats to Homeland Security, which is the evolving terrorist. The Evolving terrorist threat is of major concern since 9/11 because “its demonstrated and continued interest in advancing plots to attack the United States” (). A major concern in this area for the United States is the propaganda that is used to motivate individuals who have not participated in terrorist activities or traveled to conflict zones, teaching and training them to plot and carry out attacks on civilian populations. Another huge concern to Homeland security is the threat to our cyber-physical infrastructure. “A vast array of interdependent information technology network, systems, services, and resources enable communication, facilitate travel, power our homes, run our economy and provide essential government services” (). The everyday citizen is so reliant on technology and everything in our country is so interconnected that if the cyber-physical infrastructure would to be compromised it would create a devastating chain reaction across the country. The third concern for Homeland Security is the threat of a pandemic. Even though it is noted as being a very low probability, the impact of it happening even once would be very high impact. “Increasing global

Homeland security was developed by the United States government to protect the country from external aggression, reduce the likelihood of terrorist attacks and manage the damage that occurs in case of attacks. To this end, the government set up and reconstituted numerous agencies to aid in the fight against terrorism in the United States. The United States Department of Justice and Department of Homeland Security constitute the most prominent departments under the United States law to champion the fight against any attacks by extremist groups. Federal, State and local law enforcement agencies, as well as the United States’ military also have a role to play in homeland security. With the increasing cases of attacks and acts of aggression towards the United States, the government sought to strengthen the resolve to curb any attacks aimed at killing or maiming the citizens or destruction of government institutions and installations. In the wake of the September 11 attacks, it was apparent that stringent measures were needed to prevent attacks on American soil and protect the citizens of the country. This paper examines the duties; responsibility and intelligence methods used by the military, federal, State and local law enforcement agencies, as well as homeland security agencies in the fight against terrorism, with the aim of drawing similarities and differences.
Your Imperial Highness, in order to move forward to revitalize the National Security Strategy, our interests and objectives need to be reexamined within the new domestic and international context. The morale of the German people is slipping, our food supply is limited, and the economy is tanking. Additionally, the UK has intercepted the telegram from Foreign Secretary Arthur Zimmerman to Mexican Ambassador Heinrich von Eckhart. It is not known how the United States will respond to this information.
It is illegal to make privacy of one's life. Surveillance is a commonplace occurrence in the society today. It exists in every corner of a nation from the corner of streets to discussion topics in movies, lecture halls, theater arenas and books. The privacy word is mentioned many times till its losing taste of its meaning. Surveillance is the exercise of keeping a close watch on something, somebody or set of activities (Richards 56). Many people say that Surveillance is unscrupulous. Nonetheless, we mainly do not distinguish the reason. People only have vague intuition the fact, and this accounts the reason the courts of justice do not protect it or the victim of circumstance of such. We recognize we don’t like it, and by the virtue that it contains something too with privacy, but past that, the revelations can be ambiguous (Boghosian 67). We have been to stay in this state of operation substantially because of the threat of constant Surveillance has been consigned to the realms of scientific studies and fictional activities and moreover to unsuccessful authoritarian states. Nevertheless, these warnings are no longer fictions due to
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
Security policies are a series of rules that define what traffic is permissible and what traffic is to be blocked or denied. These are not universal rules, and there are many different sets of rules for a single company with multiple connections. A web server connected to the Internet may be configured only to allow traffic on port 80 for HTTP, and have all other ports blocked. An e-mail server may have only necessary ports for e-mail open, with others blocked. A key to security policies for firewalls is the same as has been seen for other security policies, the principle of least access. Only allow the necessary access for a function, block or deny all unneeded functionality. How an organization deploys its firewalls determines what is needed for security policies for each firewall.
Principle of Security Management by Brian R. Johnson, Published by Prentice-Hall copyright 2005 by Pearson Education, Inc.
Developing a security culture within an organisation is about encouraging staff to respect common values and standards towards security whether they are inside or outside the workplace.
A critical part of network planning involves setting up of security mechanisms. Deploying the network with security configuration provides superior visibility, continuous control and advanced threat protection across the extended network. Additionally, security procedures define policies to monitor the network for securing critical data, obtain visibility, mitigate threats, identify and correlate discrepancies.
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 study of international relations takes a wide range of theoretical approaches. Some emerge from within the discipline itself others have been imported, in whole or in part, from disciplines such as economics or sociology. Indeed, few social scientific theories have not been applied to the study of relations amongst nations. Many theories of international relations are internally and externally contested, and few scholars believe only in one or another. In spite of this diversity, several major schools of thought are discernable, differentiated principally by the variables they emphasize on military power, material interests, or ideological beliefs. International Relations thinking have evolved in stages that are marked by specific debates between groups of scholars. The first major debate is between utopian liberalism and realism, the second debate is on method, between traditional approaches and behavioralism. The third debate is between neorealism/neoliberalism and neo-Marxism, and an emerging fourth debate is between established traditions and post-positivist alternatives (Jackson, 2007).
