...Running head: Cyber Security Securing Networks Wagner, Juan ISSC342 ABSTRACT As our dependency on technology grows so does the need to protect the data contained in them. We live in a world where digital imaginary data has become just as important if not more than actual physical work these machines perform. One of the biggest jobs for any respectable firm is the ability to protect its information from the unrelenting attacks by hackers, insiders, social engineers and software exploits. this is an on going struggle that will never end. The reality is there is no way to fully and completely protect a network. The second best thing we can do as IT professionals is ensure protocols that have resulted in having a more secure network are being met. Since most of the errors in the world are human errors we must take extra consideration when securing a network. Computers don't make mistakes only people make mistakes. Finally as professionals we must do our job in researching new exploits, tools and reasons why someone would want to perform a cyber attack on said company. INTRODUCTION In the IT world knowledge is power, and there is much to be learned if a corporation is to be able to perform at an AAA level. There are many things that can go wrong in regards to intellectual property. Some of those things are certificates, classification of data, and how computing devices are used. In conjunction with the material professionals also should be actively researching...

...Lab #4 Operating Systems: Hardening and Security March 1st, 2015 Lab Assessment Questions & Answers 1. What is the one thing that a virus, a worm, spyware, and malicious code have in common? What are the differences among these three threats: a virus, a worm, and spyware? A virus, worm and spyware all have in common that they replicate themselves into the network’s system. Some of the differences between the three are that worms can edit files, viruses need a host file to propagate itself and a spyware can steal very sensitive information within the network. 2. How often should you update your antivirus protection? You should update your antivirus protection daily to always keep your network secured. 3. Why is it a best practice to have and to carry an antivirus boot-up disk or CD?

...1. Discuss common forms of attack on Microsoft systems using the text Internet, and/or your job as reference for full credit. When considering the security of a system you will need to determine all the possible threats, vulnerabilities, and attacks. You will also need to consider the appropriate tradeoffs between security on one hand, and usability and cost on the other. A threat is the possibility of system compromise. For example, a threat could be the potential for unauthorized people to gain access to sensitive information, such as credit card information or health records. Microsoft (2005) Threats usually involve confidential information. An attack takes advantage of an existing vulnerability. For example, suppose a malicious user knows that some users have weak passwords and tries guessing them until gaining access to restricted resources. It is important to realize the different types of security attacks you might encounter. Once you understand these, you will learn the appropriate countermeasures to take. Microsoft (2005) The three main types of attacks are: Disclosure of data, Corruption of data, and Denial of service. Disclosure refers to unauthorized or inappropriate access to sensitive data. This is probably the most common form of attack. An example of disclosure is a file that holds confidential payroll information. If this file finds its way into the hands of someone who should not be privy to the data, then the data has been disclosed. Data corruption is mainly...

...COMMON FORMS OF ATTACKS ON MICROSOFT SYSTEMS Corey Slate ISSC342 Professor Peter Mylonakos American Public University July 13, 2014 COMMON FORMS OF ATTACKS ON MICROSOFT SYSTEMS Ever since the Microsoft Company was founded in 1975, they have been working in the computer industry with one mission on their minds. The ability to enable people and businesses throughout the world to realize their full potential by creating technology that transforms the way people work, play, and communicate (Microsoft, 2014). Throughout the company’s journey to accomplish their mission they have had great success being a front runner in the development of operating systems for personal computers and even branching out into the mobile device world of today. With their many successes, however, as come some small setbacks that have caused the company problems in the past, the present, and surely in the future as well. What are these setbacks that can frustrate a major company like Microsoft, the answer is technology. The Microsoft Company has been using the advances in technology to lead their company to the top of the personal computer operating systems world for over a decade. They have developed many types of operating systems with many different versions to appease the different types of people and companies that require their operating systems to function on a daily level. However, with technology advancing attackers, or hackers, use the new technology to seek and exploit weaknesses...

...Removing Malware: Tools and Techniques Devan A. Dunham American Military University, ISSC342, Instructor Peter Mylonakos In the digital world, there are many tools and techniques to harm your computer, but there are also the same for protecting your computer as well. Malware, or malicious software, is software that is intended to damage or disable computers and computer systems. It is very dynamic and can be hard to detect sometimes because it may disguise itself as something that should be running on your computer. For example, after installing a program, Jim doesn’t realize that the executable file he downloaded was infected with malware named “Wajam” but disguised itself as “Software Updater” under Control Panel. It ran in the background and updated itself automatically without Jim’s knowledge. So how would Jim detect and remove this virus? First, Jim should always be aware what is running on his computer. On Windows machines specifically, opening the Task Manager and taking a quick look at processes will give the user a good outlook on what is running on the computer. Users should look for anything suspicious or unknown processes and do further research upon discovering them. Another simplified way to discover malware is to use an anti-virus program. There are many available to users and doing a quick internet search will yield thousands of programs, but sticking with reputable programs will serve its purposes. Scanning for malware and other viruses is as simple as click...
