1. Create a new file called week4.scr

2. Change the permissions on this new file to add the execute bit for user, group, and owner (sudo chmod 755 week4.scr).

3. Edit the file using Gedit

4. Enter the following lines of shell script into the file (just copy and paste):

#!/bin/bash

trap “echo You cannot press THAT key” SIGINT SIGTERM

count=1

echo "Start of week4 script"

while [ $count -le 10 ]

do

echo "Loop #$count"

sleep 5

count=`expr $count + 1`

done

echo "end of the program”

5. Save the file

6. Run the script to make sure you have no syntax errors:

• ./week4.scr

• NOTE: If you have syntax errors, you mistyped something. The script must run with NO syntax errors before you can move on. If you need help, ask.

7. Run the script and verify that you are trapping the SIGINT (signal 2) and SIGTERM (signal 15) signals properly:

• ./week4.scr

• Open a NEW, second Terminal window.

o ps –ef | grep week4.scr

▪ This will obtain the PID of your script

o kill -2 PID

▪ Verify that your trap message is displayed in the FIRST Terminal window

o kill -15 PID

▪ Verify that your trap message is displayed in the FIRST Terminal window

8. Take a screen capture of this sequence (FIRST Terminal window only) and paste it here:

...UNIX Protection Scheme Cedric Lee POS/355 Scott Stewart March 25, 2013 UNIX Protection Scheme There is an operation system that supports 5,000 users, and the company only wants to allow 4,990 users permission to access one file. In order to have a protection scheme in UNIX, a number of operations need to be performed first in order for this to work. UNIX file management hierarchy is very essential to know in order to understand and devise a plan that will allow this protection scheme to protect the files. Without knowledge of the hierarchy of the file management system within the UNIX operating system, there is no way that the 4,990 will have access to only one file. A file access control scheme will be the design of UNIX operating system. Therefore, user ids and passwords are needed in order to gain access to the system. All users of the UNIX operating system will each be given a user id and a user password. These user ids and passwords will be kept by the assigned users only. The protection of these ids and passwords depend on how well the user protects them. Encryptions and decryptions can also be used when the users are attempting to login. The administrator can put each user into different groups that allow access or deny access to certain files within the operating system. By doing this, there can be control on who can access what file due to the permission given to them by the administrator. The administrator is referred to as the super user......

...Beberapa decade lalu PT Pos adalah pemimpin pasar yang sangat dominan dalam bisnis pos dan ekspedisi. Akan tetapi seiring berjalannya waktu, muncul pesaing yang masuk ke dalam industry ekspedisi dan logistik yang menawarkan alternative lain yang jauh lebih inovatif baik dari segi pelayanan dan produk. PT Pos terlalu berfokus kepada produk yang selama ini menjadi keunggulannya, hal itu membuat PT Pos tidak melihat perkembangan industry jasa ekspedisi. Hal ini menjadi masalah, ketika pada akhirnya PT Pos tertinggal dari para pesaingnya dan gagal untuk dapat masuk kembali melawan pesaing-pesaingnya. Jenis produk jasa yang ditawarkan oleh PT.

...Neiman Marcus Hacking and Securing a POS System John Fischer Security Research Paper 9/22/2014 For several years we have been using the point of sale (POS) system for payment at major retailers. In the last year there have been several attacks on major retailers POS systems. In this paper, I will focus specifically on the breach of security at Neiman Marcus. In this discussion I will explain how to help secure a POS system. Neiman Marcus was founded in 1907 by Herbert Marcus with his sister, Carrie Marcus Neiman, and her husband A.L. Neiman. Their initial investment was $25,000. The original Neiman Marcus was on the corners of Elm and Murphy streets in Dallas, Texas. In 1913 a fire destroyed the companies building and its entire inventory. A new building was built in 1914 on the corners of Main and Ervay, also in Dallas, Texas. Neiman Marcus’ headquarters is still located in this building. Neiman Marcus is a high end retail store. The target market for Neiman Marcus is the top 2% of the income bracket of the United States, plus the wealthiest people around the world. Neiman Marcus retails high end goods such as clothes, jewelry, cosmetics, home furnishings, antiques and even rare books. Neiman Marcus also has an online store, started in 1999, that offers customers access to high end luxury goods. In 1926 Neiman Marcus first issued their holiday catalog. Many different items have been offered in their holiday catalog, including life size robots and......

...The operating system that I use for work runs on Windows 7 Enterprise and for work purposes it works well. I am in the Army so money is typically no issue when acquiring tech support from the Microsoft end as well as through here at work. If I did work for a smaller company, I might be more open to utilizing Linux into the work place. I am no expert, but I have been experimenting with the Ubunto system. One of the main differences that is clear is that Window’s 7 is a product of Microsoft which uses NT as its kernel. In order to use Windows you must pay for the product and the support, but it must be noted that most updates are free but newer versions are not. Also a great plus for Ubunto is free open source software and does not have a designated technical support center. Ubunto’s kernel is Linux which differs from Windows. This is not too much of a problem for an experienced user but for a newcomer, this is a definite negative aspect. Another difference between the two systems is that security comes already installed with Ubunto; Windows on the other hand, does not come with security installed. In order to make sure your files and network is protected you must purchase security from Microsoft or other compatible vendors. While both systems are deemed as user friendly, I seem to have a harder time with Ubunto, but I think that may be due to the many years of experience of using Windows that has led to that situation. Another key difference is that there is lots of......
