Question 1: We learned that when calling subprograms or functions that we can pass data to the subprogram or function by ‘value’ or by ‘reference’. Describe what each approach is, how it works and what the potential security disadvantage is when passing parameters by reference. An easy way to view the difference between pass by value and pass by reference is to use the explanation on (Stack Overflow, 2008). This is a great way to visualize the difference as well as the potential security issues. "Say I want to share a web page with you.
If I tell you the URL, I'm passing by reference. You can use that URL to see the same web page I can see. If that page is changed, we both see the changes. If you delete the URL, all you're doing is destroying …show more content…
This means that the data you have is stale and can be misleading. In my research one way this can cause issues is with token or certificate authorities. Each certificate is passed by value and is a copy of the original. There is a program that evaluates them each time to ensure they are accurate. This causes some issues in that the data could be replicated or stale. Pass By Reference: References the address or location in memory where the data is associated with the argument. Changes made in the subprogram will be made to the data in the calling program as well. Potential Security Disadvantage:
If a hacker can gain access to the variable, they could potentially write a null and cause an error or denial of service. At the same time they could introduce a value that is not correct thus causing the program to report inaccurate values though the program is actually working. In this scenario, a hacker could attempt to change the value of their bank account balance thus tricking the bank into thinking they have more money then they really

There are five actions taken to improve the security of a vulnerable server, enumerated as follows. 1 Fix Root Password The original password for root is “default”, which is unsecure. Attackers could easily crack the password with the brute-force mode.
It is obvious that this approach is simple to implement but has small hardware expenses. It can also provide somewhat better performance than worst-case design. 3.1.2 Data Speculation The definition of data speculation states the use of feasible incorrect logic values in dependent computations. The idea behind the concept of approximation is to implement the logic function partially instead completely.
Perhaps many are confused about the existing commands linux, this time I will discuss about the linux basic commands used along with examples of its use. 1: Seeing identification (id and group id number) $ Id 2: Looking the calendar date of the system a. Looking at the current date $ Date b. See calendar $ Cal 9 2002 $ Cal -y 3: Seeing the machine identity $ Hostname
The research study includes two measurements, the Progressive Aerobic Cardiovascular Endurance Run (PACER) test and the Situational Motivation Scale (SIMS). The first focus of the clinical experience assignment was to observe the guidance counselor administer the SIMS questionnaire to students. Two fifth grade classes were observed; students in both classes participated in a second steps teambuilding activity prior to completing the SIMS questionnaire. One of the objectives for this clinical experience was to observe how the guidance counselor administered the questionnaire. After the teambuilding activity, students in both classes received detailed instructions from the counselor on how to complete the questionnaire.
Network monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system called Marple was created by researchers at MIT, Cisco Systems, and Barefoot Networks(Hardesty). Marple involves a programming language the allows network operators to specify a wide range of network-monitoring tasks and a small set of simple circuit elements that can execute any function specified in the language.
Console Window Web Class library Control library Smart Device Console: Server terminals: Many servers use is controlled exclusively through console programs. siege: Siege is an http/https stress load tester used to test different web servers through terminal interface program. Abcde: Abcde is a CD encoder program that will rip or burn different cds to and from your computer.
The last but not the least, Hopper incorporates formal elements like value, space and lines to display the double act of looking in Morning Sun. “ The model for the painting was Hopper’s wife Josephine. She was to be become Hopper’s only female model after their marriage in the mid-20s. At the time those drawings were made, she was 69 years old” (Theophanidis, 2014). As capturing the main character in the painting, a young girl with hair in a bun sits at the middle of the bed in a bare room.
1. Standards Driven Data: Online tools and resources will be used to analyze standards used in a course. How often are they being used and are they being used appropriately? Data then will determine what needs changed and adapted to meet those requirements. 2.
Question 1: To determine the result of whether the older you get the more income you earn can be created by examining the variables and which ones are interchangeable such as age, income, and number of years one has worked at a particular job. One could create a category from interval variables by constructing a frequency distribution from which a histogram can be drawn. A frequency distribution allows us to count the number of observations that fall into each of these three categories. Another way of knowing how these variables are related is by using a scatter diagram. My income depends on a number of years I have been working in the workforce which would be the dependent variable.
Break Point 6.2 I think that the students are trying to describe what most people cannot: the effect that music has not on our minds, but our bodies. Because the mind is not involved in this physiological process, one can only begin to describe why we get "pumped," why our heart rates increase or why our moods change when we hear a certain piece of music. In the conversation in Chapter 6, each student seems to have a different way of describing how music makes them feel, which supports my belief that each student has a unique physiological approach when listening to or performing music that is unlike that of anyone else. As the chapter mentions, there is no true explanation as to why some people get goosebumps when a certain song plays and others do not. Personally, my musical tastes are all across the board, and change
80073b92 is the error code that usually pops up with errors in Windows operating systems if there is Windows registry corruption. The 80073b92 error can show up while installing Windows updates, installing a new operating system and other functions. It will become essential to find an 80073b92 fix to resolve the issues by fixing the Windows registry. Many customers have seen that they are not able to upgrade their Windows 7 running computers to Windows 10 operating systems. On trying to upgrade they get the 80073b92 Windows 10 error code with the message that, Windows Update had encountered some unknown error.
