Unit 3 Assignment 2 System Security

As we know virus protection software is a code written by one of the programing languages that we know. This code works as a search engine looking for infected files in the entire system or specific locations on the system. The idea depends on two important factors which are, search engine and viruses’ data base. The following scenario explains how people get viruses and how virus protection software works.

While digital network connectivity and electronic data exchange have paved the way to greater efficiencies in government systems, they have also opened the door to potential malicious attacks by hackers and malware that can jeopardize a system’s availability and overall security. Effective IT security rests on a careful mix of systematic security engineering, interoperable security standards and regulations, and intelligent information, procedures, technology and security personnel.

With the rapid increase in the number of attempted breaches and resulting damages, there is an increased need for user authentication, especially with numerous unknown mobile devices with which consumers are using to access to IT resources.

The first task I will be creating a check-list for the numerous procedures that will help secure the network secure, one policy I will be entering in the check-list is password policy. This type of authentication is used in most websites and many organization that requires a password like Facebook, eBay, and websites that as secure data. It can be secure depending on how decent the password is, usually the user-name is the most secure part as its just specific for that user, also for the user to make his or her password secure is by using capital letter, spaces, number and not something the hacker can guess like the same as your user-name or birthdays and your name, also the user can change and updated any time they want, and if you get either

Numerous association and organizations in this world, including government and military store a lot of secret data on PCs and send essential information around the world to different PCs. With programmers out there, there ought to be an extraordinary level of security to ensure these information and individual data. As indicated by senate insight authorities, Cyber attack is one of the main dangers in the country so this needs to compass consideration.

Hacking is among one of the many things that all users have to deal with in technology of the current times. It has been an issue for some time and is only getting worse there are ways to attempt to fight off the attempts that will eventually happen. Some of these methods involve software that is able to be purchased online or in a physical store. Other methods involve software that is able to be downloaded via the internet and installed on a computer. The question is which ones are the best to use and offer the best defense against the possible cyber-attacks from potential hackers? This and more will be explained over the course of this paper in the next few paragraphs. The take away from this should be more methods that can be used to fight against the hackers that will target many end users in the world. The defense of the end users are one of the only things that can protect these end users from harm to the computers that are owned.

Wojciech Mazurczyk and Elzbieta Rzeszutko, the author of the article “Security – A Perpetual War: Lessons from Nature”, made a lot of interesting points regarding different computer threats and defenses. The article is interesting because the authors compare these technological attacks and defenses to living organisms that have the same function in the wild. By the use of comparison, they make it easier for the readers to understand how each computer threat and defenses work. In the Philippines, many people visit computer shops to use computers for research, gaming, video chatting, etc. It is convenient for most people since it is cheap compared to buying a personal desktop or laptop. Unfortunately, many computers on a shop contain viruses

The number of significant computer security breaches around the globe is continuously growing. Typically, at least once a month. a major news story is published about an extensive data breach or a company being hacked. Many organizations are being compromised by means of software vulnerabilities, distributed denial of service attacks, and in many cases their own employees. By the end of 2015 over 4.9 billion devices will be connected to the internet and any one of them could be susceptible to an unknown number of exploits allowing an attacker access into the device (Gartner, Inc.). There are several factors contributing to the recent increase in cyber crimes and even though numerous companies have already fallen victim to them, there are sure to be more.

It should not be a surprise that the biggest vulnerability in Cybersecurity is the user (Goldman, 2010). The vulnerabilities presented by the user fall into two general categories: (1) accidental and (2) malicious. Vulnerabilities are important to those that are trying to perform unauthorized actions on an information system. For this paper, the term information system is being used generically to be anything from a home computer to a global enterprise encompassing numerous servers and storage systems. These unauthorized actions are threats to the information system. While not all vulnerabilities create threats, even a single vulnerability puts the information system at risk.

Information technology (IT) is evolving everyday and our day-to-day life is becoming more and more dependent on it. In this twenty first century, we cannot imagine ourselves without emails, online banking systems and health care systems and without World Wide Web. In other words, evolution of IT has given a modern, technologically advanced and convenient life to the society. But, over the time we are also observing explosive growth in the darker side of the IT - regarding hacking and cyber crimes. Activities like unauthorized computer intrusion, denial of service (DOS), stealing computer passwords and secure data; causing damage to computer systems and databases and causing damage to

Prevalent to the current trend now is the dependency of the society on Information technology and communication systems. Every aspect of human life is one way or the other linked and controlled by information technology tools. The importance of information technology cannot be over emphasized as its unavailability could lead to a form of disaster or the other. Pivotal infrastructures like finance, healthcare, education and security are driven by information technology. However, information technology and its benefits are accompanied by vulnerabilities and risks that can be exploited by people with the necessary technical skills. Individuals like ‘Hackers’ and ‘Cyber Terrorist’ can cause disruption to information systems, commit financial fraud and also attack computers and networks. These attacks and disruptions could result to violence against people and properties. In some cases, death, serious injuries and severe economic loss could occur as a result of these attacks.

There are several cyber security vulnerabilities that organizations and individuals need to consider to protect the integrity and confidentiality of their computer systems and networks. These vulnerabilities include software and hardware, intranet, enterprise network, wide and local area network, and transmission media. This paper, therefore, focuses on software and hardware vulnerabilities as the most important and the reasons it is the most important. The paper further focuses on the risks associated with these vulnerabilities (software and hardware) and provides the recommendations on ways to manage the risks.

An operating systems (OS) serves as the medium between the user of a computer and the hardware that it resides on. The operating system manages how programs communicate with resources in a computer, such as disk drives, microprocessor, CPU kernel, RAM ,usb external drives, network interfaces, printers, and web cameras to name a few. Operating systems interact with application’s that are built by programmers in house or commercial off the shelf (COTS) such as Microsoft Office Suite or Symantec Antivirus software. The information store on computers are essential to our way of live. Protecting this information from malicious intruders is not always practice by IT professional in an organization until it is too late.

In an age where every sophisticated industry relies on computer systems and data centers for its operations, any kind of vulnerabilities in such system might provide an opportunity for exploitation to someone with an inappropriate intention. The constant threat of digital breach and exploitation gave birth to the field of Cyber Security, which is the field of technology dedicated to protecting computer devices and information systems from unintended or unauthorized access to the software, hardware or the information they hold. It also involves preventing disruption or misdirection of the services they provide.

A specialized field in computer system security that involves securing a computer system hardware and software. Security is typically handled by a system administrator who implements the security policy, network software and hardware needed to protect a system and the resources accessed through the network from unauthorized access and also ensure that employees have adequate access to resources. A system security typically relies on layers of protection and also consist of multiple components includes networking monitoring and security software. All components work together to increase the overall security of computer system. Passwords are extremely effective system for improving system security if applied properly. Security is the fundamental component of every system design. When planning, building and operating a system we should understand the importance of a strong security policy. The easier way to protect a network into the computer system from an
