Computer Security
In the last few decades, the world saw a revolution in information and technology, and the main factor of this revolution was the computer. Computers made life easier for millions of people all over the world, especially in the United States, where the latest innovations in the field of computers take place. Information circulates with extreme speed, and a person with a computer and access to the Internet can follow what is happening on Wall Street, even if he is thousands of miles away from there. Any user of this network can buy, sell, and make money by staying in his bed. But in order to guarantee the stability of such a world where a lot of transactions occur, billions of dollars are at stake, there must be

The authenticity of the message is also important; a user has to verify that the information is received from the correct sender. Another aspect of computer security services is the integrity of a message; only authorized users can modify a message. Non-repudiation of the data is also fundamental; it “requires that neither the sender nor the receiver of a message be able to deny the transmission” (Stallings 5). It is also important that “the information resources be controlled by or for the target system” (Stallings 5); this corresponds to the idea of access control. In addition, the availability of the message is an important concept; only authorized users can access “the computer system assets” (Stallings 6). Different computer security techniques are used to guarantee these aspects.
The main way to protect the data being transmitted is to hide the message. There are two fundamental techniques used in computer security: Stenography and Cryptography. Both techniques require a transformation in the information to be sent, an identification character included in the message to recognize the sender, and also some secret information to scramble the message when sent and to unscramble it when received (Stallings 12). When the method of Stenography is used, the very existence of the message is cancelled. For example, the resolution of a Kodak CD format is 2048 by 3072 pixels, and each pixel contains 24 bits. If one bit of each pixel is used to
The proficiency and efficacy of the cyberspace in its application in accounting, finance, system designs, manufacturing etc., cannot be denied nor neglected. The reality of the twenty-first century is simple; no organization can survive without the adoption and implementation of the mechanism of information technology to their area of business. On the contrary perspective, there are several challenges that are associated with the cyberspace, among which is majorly cyber security. Recently the hackers’ activity has really skyrocketed and has become a major concern for organizations, states and federal governments and even international organizations. Several regulatory schemes are put in place to mitigate the activities of hackers across the globe.
The above stated problems are mostly related to the InfoSec principle. InfoSec principle helps in protecting information from unauthorized access, modification, disruption, destruction etc. The confidentiality, integrity, availability, non-repudiation and availability are some of the parameters which fall under InfoSec principles and understanding any security breach such as malware attacks, risk of hackers when studied in light of these parameters, can help in solving the
Some security risks involved with conducting business online are imposters, eavesdroppers and thieves. Also, there are crackers or hackers, which are people who write programs and manipulate technologies to obtain unauthorized access to computers and networks. The elements of computer security are secrecy, integrity and necessity. Secrecy is protecting against unauthorized data disclosure. Integrity is preventing data from being modified by someone who is unauthorized and ensuring that the contents of emails aren’t changed before they get to he recipient. Necessity is preventing data delays or denials. It is important to establish a security policy to protect assets, to define acceptance and unacceptable behavior and to review physical and
Homeland Security is one of the most important departments in the United States. The United States Department of Homeland Security job is to reduce our vulnerability to terrorism and lead a national effort to help prevent terrorist attacks on our nation (Computer Concept, pg. 50). As technology evolves over the course of time, computers end up playing a crucial role in homeland security.
In this paper we will look at defining the problem of data security and public administration. The reader will see the evidence gathered to get a better understanding of the problem of not securing data when sending it. The reader will learn different alternatives to how they can ensure the data is secure.
To establish a framework to maintain the security, integrity and availability of ABC 's information assets
Initially we should start with identifying and defining the four security components to ensure we have a clear understanding of what they are and how to implement them. The components of information security are Confidentiality, Integrity, and availability also known as the CIA triad. Confidentiality in Information Security is defined as the protection of information from disclosure to unauthorized parties (Chia, 2012). Integrity in Information Security is defined as protecting data from being modified by those not authorized to do so. Authentication is defined as proof that the individual requesting access is who they say they are. Non-repudiation is an assurance that someone cannot deny something, in information security this might be completed
The information age is the age we live in today, hence we must make sure that the use of the information readily available to many people is not abused. There are many different types of security threats to the average person, business or even government. The risks faced by individuals and entities are rising, thus measures to avoid these privacy and security breaches would be discussed accordingly assisting and allowing firms to remain, fraud free and protected.
Speaking of life’s experiences, there was one night on Security 8 that became something that would haunt me the rest of my life. Security 8 was an entry control point to the Elephant Cage area. The Elephant Cage measured about 850 feet wide by 100 feet high and contained a circular arrangement of antennas. The antennas could locate signals thousands of miles away with an accuracy of three degrees or better. The 6922 Electronic Security Squadron operated the elephant cage, which was used to gather intelligence during the Cold War. Just in case you wondered, there were no elephants housed there while I was at Clark.
In the previous five years, cybersecurity has turned into the most looked for after calling around the world. More than 90 percent of respondents to an overview directed by the Ponemon Institute (2011) detailed being a casualty to cyberattacks amid the most recent year, costing all things considered more than $2 million for each association. This number keeps on ascending as the two programmers and security devices progress. As indicated by PwC, roughly 33% of all U.S. organizations are as of now utilizing digital protection (Lindros and Tittel, 2016).
Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
In today’s world technology has evolved to the point where a large amount of information is stored in cyberspace. It is because of this type of storage people around the world have an easier time at accessing information than ever before. The time before the late 20th century gathering information was long and tedious to get a book that the library did not own would take at least a couple of weeks depending on the time period or it may not have been possible to obtain that book. But now people can access a vast amount of information in a matter of minutes. Example, in modern times if someone wanted to know about a different culture they could simple look up the information on a computer or any device that had access to
As we evolve through time the technology evolves with us. With our accomplishment in technology we reached beyond our imagination, some things which our ancestors would only dream on having. But while the technology can be used for good deeds some want to take advantage of it and gain personal profits. So, countermeasures were created for defending against them. The system security is a defence mechanism projection against illegal access in a User’s/Owner’s computer or other technology gadgets that contain personal information without the Owner being aware. The system security covers Networking Protection which is an accidental downloading of software codes like computer viruses, spam, worms, Trojan horses, logic bombs, spyware, and adware, that create an annoyance, steals, harms or alters data or cripple system capacities. In the meantime, it also covers Physical Protection preventing others to steal or access your personal gadgets. Programs for protection have been created for a long time and are still being created for the cause of fighting the threatening programs. The battle of anti-threatening
Safety of information is the most valuable asset in any organization particular those who provide financial service to others. Threats can come from a variety of sources such as human threats, natural disasters and technical threats. By identifying the potential threats to the network, security measure can be taken to combat these threats, eliminate them or reduce the likelihood and impact if they should occur.
A threat agent is the facilitator of an attack however; a threat is a constant danger to an asset.
