NETWORKING AND SECURITY ISSUES

Handout 1 Overview

Introduction

Many organizations have invested vast amount of money in computer networks, only to find out that although it is providing means of improving the efficiency and productivity of the organization but it also exposes the Organization to possible attacks and threats. Such attacks have been the most challenging issue for most network administrators and a worrying topic for administrators.

Organizations need to share services resources and information but they still need to protect these from people who should not have access to them, while at the same time making those resources available to authorized users. Effective security achieves these goals.

The greatest threat to computer systems and their information comes from humans, through actions that are either malicious or ignorant. When the action is malicious, some motivation or goal is generally behind the attack. For instance, the goal could be to disrupt normal business operations, thereby denying data availability and production.

April 13, 2000, 3:55 P.M. Pacific time: The Web site for the Motion Pictures Association of America (MPAA) is suffering intermittent outages, and the organization suspects computer vandals are to blame. A source inside the organization, who asked not to be identified, said that the MPAA is currently “experiencing problems with their public Web site, and they suspect a denial-of-service attack.” The attack was first rumored on http://www.hackernews.com/, a Web site for news on computer hacking.

Most of the attacks are becoming more frequent and more damaging, and they are using well-known techniques and methods to exploit vulnerability in security policies and systems.

Social Networking in Business and Human Resources

...Social Networking in Business and Human Resources Rebecca Moriarty Troy University Introduction to Information Systems IS 3300 XTIB Dr. Rodger Morrison February 27, 2011 With the growth and explosion of popularity of the internet in the recent past, there has been a significant increase in the use of social networking sites. More than ever people and businesses are now using the internet with the purpose of having access to social networking sites. It is in these sites that they are able to set up networks with their friends, co-workers and family from all over the world and be able to share their thoughts and ideas on virtually everything spanning from personal issues to work and business advertising. Social networking sites have therefore become a subject that is drawing a lot of research from all over the academic world. In the recent past it has become difficult for people working in human resources departments to avoid the distractions that are being introduced with the rampant use of social networking sites. In the world today millions of people are now subscribed to the providers of the social networking services such as Facebook, MySpace, LinkedIn, and Friendster among many others.

Social Networking

...Information Systems Course Project Four Case Study Social Networking 1. Facebook, MySpace, and LinkedIn are using disruptive technology to run their business. Disruptive technology is a new way of doing things that initially does not meet the needs of existing customers. Disruptive technology tends to open new markets, and enter into the low end of the markets to displace high end competition. Sustaining technologies tend to build on established markets that provide cars that gain better gas mileage or faster cars, as well as cheaper products. MySpace allows users to interact in a way unparallel before its emergence. Facebook has surpassed MySpace as far as active users. Facebook has many features, but it is its chat feature, one that populates a friends list that has surpassed the features of America Onlines’ Instant Message. LinkedIn is geared for the professional or business orientated as opposed to Facebook and MySpace that are geared to finding and keeping in touch with friends and family. LinkedIn members invite people to be connections instead of friends. LinkedIn is a contact management system as well as a social network, and has a question-answer section similar to Yahoo Answers. LinkedIn is a site to network for future positions. Develop your profile to show case your skills in hope of a network “connection.” 2. Some business challenges facing social networking sites are remaining innovated and security issues. Business Driven Technology text relates that the first...

What are the drawbacks of networking computers? 4. What is the future of networking computers? 5. Is computer networking still at infancy, Discuss? Question 1: What does computer networking accomplish? Computer networking is the interconnection of two or more computers to share resources. Computer networking has evolved beyond the sharing of resources; it allows people and machines to communicate, using some of the advanced features or services. Computer networking has brought about increased productivity, cost reduction and synergy between users. Other accomplishments of the computer networks include: • File sharing and management: One of the major accomplishments of computer networking is file sharing, which includes remote file accessing. Organizations or individuals can share documents irrespective of their location provided their PCs are interconnected. It saves time, and provides a more efficient means of transferring data, rather than using storage device to copy and transport data to the other user. • Resource sharing and management: Another important achievement of computer networking is resource sharing. All computers in a network can...

...Introduction Social networking sites have become very popular avenues for people to communicate with family, friends and colleagues from around the corner or across the globe. While there can be benefits from the collaborative, distributed approaches promoted by responsible use of social networking sites, there are information security and privacy concerns. The volume and accessibility of personal information available on social networking sites have attracted malicious people who seek to exploit this information. The same technologies that invite user participation also make the sites easier to infect with malware that can shut down an organization’s networks, or keystroke loggers that can steal credentials. Common social networking risks such as spear phishing, social engineering, spoofing, and web application attacks attempt to steal a person’s identity. Such attacks are often successful due to the assumption of being in a trusting environment social networks create. Security and privacy related to social networking sites are fundamentally behavioral issues, not technology issues. The more information a person posts, the more information becomes available for a potential compromise by those with malicious intentions. People who provide private, sensitive or confidential information about themselves or other people, whether wittingly or unwittingly, pose a higher risk to themselves and others. Information such as a person’s social security number, street address, phone number...

Effects of Media

...Griffyn Carpenter 4/24/15 Media Ethics- Final Paper Prof. Ceravolo Ethical Issues within Social Media Sites: The Past, The Present, and The Future Social media came onto the scene in a huge manner with hype that hasn’t been matched since but with that huge hype that it brought, it brought along some problems as well, problems that social media users are still anxiously waiting to be fixed. Social media has grown so rapidly that network executives and engineers have had a hard time keeping media websites up to par with the expectations of the public and keeping people interested as well as making sure they are updating security features too. The lack of care for other people’s personal information it feels like in a sense, have created a few current and potentially fatal future problems for these social networking sites. Unfair and/or undefined privacy laws, the hacking of user profiles, and the lack of technological advancement used within sites by website personnel all pose threats for some social media sites now and as time progresses. The actions they choose to put in play now and over the next few weeks, months, and years will determine how successful some certain sites are and how long we can expect their media presence to play on. Privacy is a state where in an individual can have his/her information in seclusion, resulting in a selective revelation of one’s identity and information and which they choose to reveal it. Privacy can also mean “anonymity” in case...
