This document discusses three security risks: 1) Allowing unrestricted TCP traffic through a firewall could enable DNS attacks. 2) A mislabeled USB drive found in an office poses a malware risk. 3) An attacker disguised as a technician used social engineering to gain physical access to a company's network switches, putting the LAN at risk. Countermeasures like access controls and input validation can help mitigate these types of risks.

(administrative, technical and/or physical control) 1. Allowing TCP traffic to pass through the
firewall to the domain name system (DNS) 2. Finding a USB drive in your office labeled
"important info" 3. A. An attacker, who pretends to be an electrical technician, gainod access to
XYZ company and then to one of the switches that connects the LAN of the first floor to the
router by using physical social engineering technique.

1. The invasive spotted lanternfly has made it to Vermont. It feeds on apples and maple trees and deposits honeydew that attracts other pests and encourages mold growth. The Vermont Agency of Agriculture is therefore very concerned. As a scientist working for the US Department of Agriculture, you're working to better understand the genetic bases of traits in this emerging crop pest species. You've identified three important recessive traits, cold tolerance ( t ), super sweet honeydew ( h ) , and rapid development (d) that could affect their ability to colonize Vermont. Limited cold tolerance ( T ) , regular honeydew ( H ) , and normal development ( D ) are dominant. You know these traits are linked to some degree based on your observations of inheritance patterns. You want to map these traits to the chromosome and determine the genetic distance between the loci. You cross purebreeding spotted lanternflies with cold tolerance, super sweet honeydew, and rapid development with purebreeding spotted lanternflies with limited cold tolerance, regular honeydew, and normal development. You then testcross the resulting F1 progeny and observe the following 1000 F2 progeny. A) Determine the gene order and fill in the progeny genotypes in the table above using the gene annotations noted above. (4 pts) Draw a genetic map indicating the gene order and genetic distance between all 3 gene pairs in units of map distance (or cM ); show your work for full credit. Note: You can calculate distance of outer loci by summing. ( 9 pts) B) Determine if the observed frequency of double crossovers is consistent with the expected frequency by calculating the interference value (I). Interpret the results as the % fewer double recombinants than expected. (4 pts) .

1. The data in the following table present revenues and expenditures by categorized type for the School of Public Affairs at Enormous State University. As with most elite programs at state universities, the school has accepted missions of teaching, research, and service to the university, state, and nation. The data include budgeted and actual data for three years and the proposed budget for fiscal 2014-2015. Your task as a budget analyst is to learn as much as possible about the operations of the school and its plans for the budget year just from these data. In particular, you should look for trends, changes in shares and ratios, and the categories that are particularly important in driving the finances of the school. A few notes about the reported data: First, the state appropriates money to the university and then the central administration distributes that money to the various operations on campus. That is the source of the state appropriation number-it has been assigned to the school, so this number for 2014-2015 is an actual. All others are part of the request. Second, the central administration charges the school for the services that it provides (central library, computer networks, etc.). This charge is the assessment number in the table. It is based on .
