Over the last 10 years, computers have increased in speed and capacity while decreasing drastically in price. Computers that where once used in the corporate environment, are now slower than typical household computers. While this change occurred, telecommunications have improved to allow computers to communicate easily from remote locations, adding great opportunities for illegal activities. Data can be changed or destroyed, systems can be made to malfunction and long distance charges can be avoided. One of the biggest challenges today is to control the network security. Network security is having protection of networks and their services from unauthorized access, destruction, or disclosure. Malicious acts bring up the important topic of disaster recovery. Companies must have up to date copies of their important documents and software to prevent extended downtime. The saved information will let the company’s employees continue to work while the IT department deals the damaged media.
In 2002, computer virus attacks caused companies roughly $20 billion to $30 billion up from $13 billion in 2001. This number continues to grow as more computers are sold. Users must realize the risk of the internet and file sharing before the statistics can decline. Examples are peer-to-peer download software, instant messaging channels, and email. These examples sound like home user issues but the reality is that employees are always finding ways to use this software in the working environment. In the end, it jeopardizes the network and costs companies money. Software companies have developed ways to deal with computer viruses and email spam in an automated fashion. Some can be free for personal use and others are expensive intended for corporate level networks.
Confidentiality in computer systems prevents the release of information to unauthorized people. Individuals who trespass into someone else’s computer system or exceed their own authority in accessing certain information, violate the legitimate owner’s right to keep private information secret. Integrity of electronically stored information ensures that no one has tampered with it or modified it without authorization. Any unauthorized corruption, impairment, or modification or computer information or hardware constitutes an attack against the integrity of that information. Many of the malicious hacking activities, such as computer viruses, worms, and Trojan horses, fall into the integrity category. The same is true for individuals who purposefully change or manipulate data either for profit or some other motivation, such as revenge, politics, terrorism, or simply for a challenge.
Internal computer crimes are alterations to programs that result in the performance of unauthorized functions within a computer system.
The use of hacking to identify weaknesses in computer security has become an increasingly controversial issue in recent years. Awareness of this issue is important, because our ever increasing reliance on technology means that breaches in computer security have the potential to have wide-ranging and devastating consequences to society, worldwide. This essay will begin by clearly defining the term ‘hacking’ and will examine the type of people who hack and for what reasons. There will then follow a discussion of the moral argument on hacking before examining a few brief examples. The essay will then conclude by arguing against the use of hacking as a means of identifying weaknesses in computer security.
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
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
What concerns the government of the United States most is the security of the critical infrastructure from the cyber threats. The nation is depending heavily on the technology in most of its critical sectors to keep it up and running. Thus, this makes its more vulnerable to cyber-attacks from outsiders and insiders. Therefore, its protection must be a priority.
ABSTRACT : This paper describes the basic threats to the network security and the basic issues of interest in designing a secure network. it describes the important aspects of network security. A secure network is one which is free of unauthorized entries and hackers. INTRODUCTION
In the beginning hackers hacked into computers and networks out of curiosity or for fun, but more recently they have been caught using their skills for personal financial gain (Stein). Hackers who use the skills for crimes are sometimes referred to as black hatters and the hackers whom are working for good, such as working for law enforcement, are referred to as white hatters (Chamelin475). Six months into the year 2010 cyber-crimes had jumped from sixty million to one hundred-eighty million cyber-crime cases (Chamelin475). One of the most popular forms of cyber intrusion is through malware or malicious software. Malware is any software with the intentions of blocking computer use remotely, to covertly steal computer data, to secretly intercept computer data, or to subvert the transmission of data for personal profit. Most malware is...
As electronic commerce, online business-to-business operations, and global connectivity have become vital components of a successful business strategy, enterprises have adopted security processes and practices to protect information assets. But if you look at today's computing environments, system security is a horrible game of numbers: there are currently over 9,223 publicly released vulnerabilities covering known security holes in a massive range of applications from popular Operating Systems through to obscure and relatively unknown web applications. [01] Over 300 new vulnerabilities are being discovered and released each month. Most companies work diligently to maintain an efficient, effective security policy, implementing the latest products and services to prevent fraud, vandalism, sabotage, and denial of service attacks. But the fact is you have to patch every hole of your system, but an attacker need find only one to get into your environment. Whilst many organisations subscribe to major vendor's security alerts, these are just the tip of the security iceberg and even these are often ignored. For example, the patch for the Code Red worm was available some weeks before the worm was released. [02]
Society has become ever-increasingly dependent upon technology, more specifically, computers to conduct personal and business transactions and communications. Consequently, criminals have targeted these systems to conduct information and cyber warfare, which can include politically motivated attacks and to profit through ill-gotten means. In an article written by Koblentz and Mazanec (2013), cyber warfare is the act of disabling an enemy’s ability to use or obtain information, degrade its ability to make decisions, and to command its military forces. Additionally, information warfare is composed of cyber warfare and related to the protection, disruption, destruction, denial, or manipulation of information in order to gain a benefit through the technologies (Taddeo, 2012). Accordingly, as technology becomes readily available to various entities, the ability to conduct or perform warfare through technological means is multiplying.
Hackers are insidious beings who can wreak havoc on unsuspecting computer users and under protected systems. Predominantly, hackers attempt to corrupt systems in an effort to gain access to information that can be used for financial gain. However, hackers may also attempt to steal political information on political issues in order to gain information or knowledge that will benefit one political party over another. The daunting task of realizing what is considered a threat is the responsibility of information technologies (IT) executives (Rosenthal, 2002). Regardless that personal reason to hack a system, it is illegal and dishonest; therefore, stiff penalties and fines are handed out to those caught intruding another system without permission.
Protecting your personal information, both on your personal computer and in other places such as your bank or your job, has become more difficult with the massive growth of the internet and the expertise of some unsavory characters called hackers, crackers or phreakers. Whatever they choose to call themselves, they are theives, plain and simple. Some people still question whether or not hacking should be illegal. I think it's obvious that what hackers do is illegal. A personal computer is personal and the information on it is private. When a hacker invades that privacy, he/she is trespassing and when they take your personal information they're committing a form of thievery (Ludlow). In addition to hackers, we now have marketers invading our privacy through the use of cookies (Rodger).
In this globalized arena, with the proliferating computer users as well as computer networks, risks associated like Malware attacks are also multiplying. As the proverb
Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
As of today, many members of society have become very dependent on the use of technology. We rely on the Internet for banking, buying things, and staying in touch. Businesses rely on their networks for interacting with clients, processing transactions, reaching new markets. Transportation, financial, energy, and communications systems, as well as our government and military, rely heavily on computer networks to function. This is how you get your electricity, your Social Security check, and your veterans benefits. The use of computers and the networks related to them has developed problems concerning cyber security. Cyber security is an important issue to be considered if people want protection from malicious people and software coming from the internet. Cybercrime primarily are individuals who seek personal gain and most computer network threats come fro...
Malicious code is a real danger to modern systems. Most systems nowadays do not work in isolation; they are more likely to be connected to other systems and sometimes they can even be dependent on them. Therefore an attack on one of the systems in the network is a potential attacking attempt to any other systems, with which it is interacting. Therefore, it is inevitable for any networked or Internet-connected computers to deal with malicious code attacks at some point. Businesses lose billions of dollars each year because of malicious code attacks. Responding to the attack and restoring all the data on the computers is a time-consuming and expensive task. It is a much better practice to try preventing it through organizing and maintaining effective defenses. However, it is important to keep in mind that there is no one general solution that can help to prevent all the attacks. Attackers are constantly looking for new ways to take advantage of systems’ vulnerabilities and find new ones. That’s why organizations have to not only defend themselves against existing attack methods, but also try to predict and prevent new attacking techniques. It means that computer and network security is a never-ending challenge and expense.
