...Lab #6 – Assessment Worksheet Identifying and Removing Malware on a Windows System Course Name and Number: _____________________________________________________ Student Name: ________________________________________________________________ Instructor Name: ______________________________________________________________ Lab Due Date: ________________________________________________________________ Overview In this lab, you used AVG AntiVirus Business Edition to identify the viruses, worms, Trojans, malware, or other malicious software found on a compromised Windows machine. You completed a scan of the entire computer, learned how to exclude folders to avoid false positives, and understood the importance of maintaining the signatures database. You discovered the difference between a full computer scan and a Resident Shield scan. Finally, you also permanently removed the malware identified by the antivirus software and scheduled the scan to run automatically. Lab Assessment Questions & Answers 1. Why is it recommended to update the antivirus software’s signature database before performing an antivirus scan on your computer? updating the antivirus software with the latest virus definitions ensures the software has the latest information to identify and quarantine threats. 2. What are typical indicators that your computer system is compromised? slow response opening, operating system not booting up correctly or no functioning normally, event logs reporting numerous unusual alerts...

...University of West Florida Electrical and Computer Engineering Digital Logic and Computer Systems EEL 3701L Lab 6: BCD to Seven Segment Display Decoder Due: November 3, 2014 Meghan Szatkowski, Brandon Burrows, Michael Long Abstract: For this lab we were to create a circuit that displays decimal numbers from binary numbers since most humans are not capable of reading binary. Using a 7-segment display we are able to achieve that by converting the BCD value into a 7 bit output. The 7-segment display has 7 LEDs and a certain amount of voltage triggers each of the 7 segments to produce a decimal number. Procedure 1. Create a truth table for your 4 bit input and the corresponding output necessary to light the proper segments of the display. For example, if the input is represented by WXYZ and the output is identified as ABCDEFG then if the input is 0000, all outer LEDs should be lit while the middle LED should be off. Once you create the rows in a truth table for the other 9 combinations, find the function for each segment. 2. Depending on whether you are dealing with more 0s or 1s, choose NAND or AND gates to implement each segment function. 3. Wire the input DIP switches to the decoder input. Note that you have 2 3x8 decoders. You will need to use the inputs and enable lines to combine them in order to implement these 7 functions. 4. Wire the NAND or AND gates to the proper outputs of the decoders in order to implement the functions for each segment...

...Anthony Purkapile Introduction Information security continuous monitoring is defined as maintaining ongoing awareness of information security, vulnerabilities, and threats to support organizational risk management decisions. This publication specifically addresses assessment and analysis of security control effectiveness and of organizational security status in accordance with organizational risk tolerance. Security control effectiveness is measured by correctness of implementation and by how adequately the implemented controls meet organizational needs in accordance with current risk tolerance. Organizational security status is determined using metrics established by the organization to best convey the security posture of an organization’s information and information systems, along with organizational resilience given known threat information. This includes Maintaining situational awareness of all systems across the organization Maintaining an understanding of threats and threat activities Assessing all security controls Collecting, correlating, and analyzing security-related information Providing actionable communication of security status across all tiers of the organization Active management of risk by organizational officials Purpose The purpose of this guideline is to assist organizations in the development of an ISCM strategy and the implementation of an ISCM program that provides awareness of threats and vulnerabilities, visibility into organizational...

...3. What are three modes of SELinux? Explain their basic functionality. Enforcing: SELinux policy is enforced/SELinux denies access based on policy rules Permissive: SELinux policy is not enforced/SELinux does not deny access, but denials are logged for actions that would have been denied if running in enforcing mode. Disabled: SELinux is disabled/Only DAC (Discretionary Access Control) rules are used. 4. Consider the following firewall rule, and describe what this permits or denies. Allow http (web) traffic through SSL using SSH & allow ICMP pings, while denying all other traffic. 5. What command would you use to allow all the traffic from the loopback? iptables -A INPUT -i lo -m ACCEPT iptables -A OUTPUT -o lo -m ACCEPT 6. What command would you use to view the network port configuration for the iptables? /etc/network/interfaces 7. If a service is to allow in one place and to deny in another, what is the outcome? Allow, because deny is the file pulled first and then the allow file, so the last one pulled is to allow. 8. Is the order of the rules important? If you deny something within the IP network layer, but permit something within the TCP transport layer that uses IP network layer that you just denied, will your TCP traffic be permitted? Yes. Because the "allow/permit" is in the next layer and pulled after the Network layer where you had the "deny", it will work as this is the last information pulled and enforced. 9. If one of the files does not...

...IS3110 Lab 6 DAWOOD ALRUBAYE 1. Why is it important to prioritize your IT infrastructure risks, threats, and vulnerabilities? Because you need to know which is most important and which is negligible. In some cases, protecting your infrastructure from a high priority threat is more important and so you may want to protect against that even if it leaves you vulnerable to low priority threats. This mainly just shows you which areas need your attention the most. 2. 2. Based on your executive summary produced in Lab #4 – Perform a Qualitative Risk Assessment for an IT infrastructure, what was the primary focus of your message to executive management? * Setting up security measures through various means. * Forcing users to update password every X number of days. * Educating users. * Firewalls * Anti-malware 3. Given the scenario for your IT risk mitigation plan, what influence did your scenario have on prioritizing your identified risks, threats, and vulnerabilities? 4. What risk mitigation solutions do you recommend for handling the following risk element? User inserts CDs and USB hard drives with personal photos, music, and videos on organization owned computers. * A good antivirus program and have all devices scanned as soon as they are plugged in. * Educate employees. * Disable optical drives/USB ports (if they are not needed) 5.

...Question 3 a). The needles are arranged vertically pointed up, outwards, and are stuck close to one another; attached in clusters. b). In a bundle, there are two leaves in a bundle. c). Pine leaves have needles, instead of flat leaves, like the broad-leaved trees. The needles help to survive winter’s hardship. For example, the needles cut evaporation so trees can save water, which is very useful during the winter season. Broad leaves trees, produce new leaves every spring. Photosynthesis occurs rapid in broad- leaved trees, unlike the pine leaves. d). Pines are called evergreens because the tree does not shed its leaves during the fall, they stay green all year around. e). Pine roots and fir are some plants that we’ve studied in the lab that are evergreen. f).
