Introduction Robust information systems and communication networks have become essential in social and economic development across the world. Networking and computing are currently utilities in the same way as water supplies and electricity. For this reason, the safety and availability of information communication systems are becoming of increasing concern. Computer security is essential to any institution and government agency and with the ever-increasing rates of computer-related crimes, it is essential to establish security program capable of preventing the impact of such threats. Various institutions globally are increasingly integrating advanced information communication technology infrastructure and applications in their core operations …show more content…
These incidents range from simple denial of service attacks launched by script kiddies to more sophisticated data exfiltration that can lead to PII compromise and loss of sensitive intellectual property and information. For instance, in October of 2012, a group of hackers broke into thousands of computer accounts belonging to more than 12 Universities in what was seen as a protest against the increase in the cost of tertiary education. According to The Chronicle of Higher Education (2012), the group named “Team GhostShell” posted a list of their targets that included Harvard University, University of Tokyo and University of …show more content…
A close analysis of the current global security concern is reflected in the objectives of various learning and global institutions’ information security programs. A number of institutions including University of Colorado, Harvard University and University of Missouri share a common theme in their objectives. Top on the list of such objectives is the need to establish guidelines that allow users of their particular information systems practice good data stewardship, ensuring reliability and availability of their systems and most important the need to protect the system as well as other information assets from unauthorized access, modification or sharing (University of Missouri, 2013). One of the features of a well-developed security system includes well-drafted and implemented security policies. According to President and Fellows of Harvard College (2013), information security policy ensures the protection of the institution’s technical resources as well as maintaining the systems integrity and securing the privacy of confidential data. In a broader perspective, the security policies include password policy, access policy and confidentiality policy. Security policy ensures the maintenance of acceptable levels of the system’s

The topic for week 3 of Computer Ethics was based upon an IT security policy in relation to a company’s ethics. The discussion board began with how training as well as education needs to be implemented throughout the business to ensure confidential information is not sent out without encryption or following other procedures put in place. This not only maintains the integrity of the company, but also makes the employees accountable as well. This can be accomplished by a well defined security policy and procedures which outlines the plan of action and the implementation. Many agreed a well documented plan needs to be kept updated as well as conveyed to the rest of the staff so everyone knows what their role is. In addition, Dawan pointed out that a security policy is a “living document” which is one that is forever changing to try and keep up with hackers. Many also agreed it is imperative everyone in the organization needs to be trained on the security policies at an organization.
Over the days, hacking is becoming unstoppable. The effect of hacking a computer is numerous, some are trivial while others have caused serious damage. For this terrible situation to stop and because computer science is my passion, so I am doing this research paper. Hopefully, through the essay, readers will be provided with knowledge covering the influence of computer hacking and the way society tried to minimize those effects. 2.
With the increasing use of emerging technologies and the associated information security threat threshold, Ohio University has adopted the NIST 800-53 security control framework to support their regulatory compliance efforts. NIST 800-53 is being implemented to provide a comprehensive set of security controls. This control framework is responsible for instituting minimum requirements that meet approved standards and guidelines for information security systems. It provides a baseline for managing issues relating to mobile and cloud computing, insider threats, trustworthiness and resilience of their information systems. NIST defines the standards and guidelines to be adhered to meet the cyber security control that align to FISMA expectations.
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
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
“A hacker is someone with deep knowledge of and great interest in a system. A hacker is someone who likes to delve into the inner workings of a system to find out how it works.”2 The definition of a hacker has been skewed in recent years by the press to connotate people who break into computer systems. The term has also evolved to represent people who protect computer systems and those that break into them. These newly termed hackers can be classified into three categories white-hat, black-hat, and gray-hat hackers. White-hat hackers are employed by corporations and work on the good side to secure computer systems without breaking into them. Black-hat hackers work on the bad side and attempt to compromise systems in illegal ways. Gray-hat hackers occupy the gray space of hacking and break into systems to learn and expose flaws, often as a service to the computer community. The ethical line dividing white-hat hackers and black-hat hackers is clear. However, the line that separates gray-hat hackers from black-hat hackers is constantly shifting in the new global network. Hacking that may have been considered ethical yesterday may not be true today due to the impact on global systems in the form of dollars loss and downtime.
My exposure to the technicalities of Cybersecurity began during the first semester of my Bachelor’s degree in Computer Sciences. I decided to enroll in a course titled CISE L1( Certified Internet Security Expert Level 1) on Ethical Hacking and Internet Security which turned out to be an insightful experience involving cyber attacks and their countermeasures. The implementation lab in this course included gaining hands-on experience in tools like ProRat for Remote Administration, OphCrack to retrieve lost passwords, Cain & Able for ARP Poisoning and IP snooping, TrueCrypt for data encryption and Acunetix for Penetration Testing and auditing. Also, complex attacks like SQL Injections, DDos Attacks and hacking WPA networks were conducted in real-time scenarios. This experience has also further confirmed my strong suspicion that continuing my study of Cybersecurity in a graduate program is the right choice...
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 se...
Nowadays, the information is the most treasured asset in an organization, due to it along with the experience represents the input necessary to take appropriate decisions and consequently to have success in the business. Almost all the information and knowledge related with the processes business, goods and services offered by a company, is processed, managed and stored through technology and information systems, thus the security of information has become increasingly important and plays a critical role in the enterprise government.
For thousands of years cryptography and encryption have been used to secure communication. Military communication has been the leader of the use of cryptography and the advancements. From the start of the internet there has been a greater need for the use of cryptography. The computer had been invented in the late 1960s but there was not a widespread market for the use of computers really until the late 1980s, where the World Wide Web was invented in 1989. This new method of communication has called for a large need for information security. The internet allows people to communicate sensitive information, and if received into the wrong hands can cause many problems for that person.
Privacy exist wherever personal information or other sensitive information is collected, stored, used, and finally destroyed or deleted – in digital form or otherwise. The challenge of data privacy is to use data while safe-guarding individual's privacy preferences and their personally identifiable information. The fields of computer security, data security, and information security design and utilize software, hardware, and human resources to address this issue.
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.
One particular crime that could be committed by employees who use the internet at work is hacking. Hacking is one of the most well-known types of computer crimes, in this context, the term refers to the unauthorized access of another’s computer system (HG.org Staff, 2015). This means that if the employee in not allowed to use the internet, for personal use, than there is a possibility that they could get charged for such crime. Because the policy will state they do not have the authority to access the organizations computer system for personal use. In addition, they must know that all use of computers systems while at work will be monitor, including e-mails. Piracy and cyber terrorism are other crimes that one can face when using a computer
