Complete the following assignments:

  • Chapter 12: exercises # 1 - 6, and 11

1. A major university in Illinois used to place the computer output from student jobs on a table in the computer room. What kinds of security problems might computer services encounter with a system such as this?

2. You have forgotten your password, so you call the help desk and ask them to retrieve your password. What has just happened and what is its significance?

3. Create (on paper) a simple example of a substitution-based cipher.

4. Create (on paper) a simple example of a transposition-based cipher.

5. Using the Vigenére Cipher and the key NETWORK, encode the phrase “this is an interesting class.”

6. Using the transposition-based cipher from this chapter and the same key, COMPUTER, encode the phrase “birthdays should only come once a year.”

11. One feature of a firewall is its ability to stop an outgoing IP packet, remove the real IP address, insert a “fake” IP address, and send the packet on its way. How does this feature work? Do you think it would be effective?

Thinking Outside the Box #4: You have a computer at home with a wireless MIC and wireless router. List all the security measures that should be employed so that your home network is secure.

Identify another, different policy issue that impacts or interests you. This policy issue can be at the local or state level. Research the policy context, implementation, effectiveness, and evaluate it using the criteria laid out in your lesson. Analyze the policy, then draw conclusions and make recommendations about the policy’s future and effectiveness. Present your findings uploading an entertaining PowerPoint briefing (minimum 10 slides with images on each slide).

The exercise requires the completion of various tasks ranging from analyzing potential security issues with a university's job output system to encoding phrases using different ciphers. Special emphasis is on understanding the implications of these security measures and policy issues.

Security Problems in University Computer Services

The practice of placing student job outputs in an open space poses multiple security challenges. Firstly, unmonitored access allows unauthorized individuals to view sensitive information, potentially breaching confidentiality (Fitzgerald, 2018). Secondly, the system is prone to identity theft, as students’ personal information can be exposed. Additionally, this practice can lead to the loss of documents if users do not collect them promptly, which can disrupt administrative processes (Harris, 2019).

Password Retrieval Significance

When a help desk retrieves a user’s forgotten password without proper verification, it raises significant security concerns. This scenario indicates a vulnerability in the security protocols that govern access to sensitive information (Howard & Ford, 2020). The implications are significant; if unauthorized individuals can access this simple password retrieval mechanism, it can lead to larger security breaches, compromising an entire network (Bertino & Islam, 2017).

Substitution and Transposition Ciphers

Substitution ciphers replace each letter of the plaintext with another letter. For example, using a key that shifts each letter forward by three positions (A=D, B=E, C=F, etc.), the word "HELLO" becomes "KHOOR."

On the other hand, transposition ciphers rearrange the positions of characters. For example, the phrase “MEET ME AT NOON” could become “MTNAOEEMOO,” where characters are rearranged based on a specific key.

Encoding with Vigenére Cipher

Using the Vigenére cipher with the key “NETWORK” to encode “this is an interesting class,” the encoded result would be calculated based on the relevant character shifts dictated by the key. Each letter in the phrase is shifted according to the corresponding letter in the keyword repeating as needed, ultimately yielding a more secure form of obfuscation (Kahn, 1997).

Firewall IP Packet Manipulation

The firewall feature allows for the modification of outgoing packets to conceal the sender’s real IP address. By replacing it with a "fake" IP, the firewall adds a layer of anonymity to the connection (Zwicky, 2000). This prevents potential attacks targeting the actual IP address, though it may also lead to security risks such as the blockage of legitimate communication (Dreger, 2019).

Securing a Wireless Home Network

To secure a home network with a wireless router, one should implement several measures:

  • Change default passwords for device admin access.
  • Use WPA3 encryption for wireless security.
  • Regularly update router firmware to patch vulnerabilities.
  • Disable WPS to avoid easy pin-based access.
  • Implement strong passwords for Wi-Fi access.
  • Utilize a guest network for visitors.
  • Disable broadcasting of the SSID for added security.

Policy Issue Research: Gun Control

The policy issue of gun control continues to be a pertinent matter at local and state levels across the United States. Through research into the legislative context, one can evaluate the effectiveness of current gun control measures implemented to reduce violence and enhance public safety (Cook & Ludwig, 2003).

The analysis indicates that while certain restrictions, such as background checks, have proven effective, loopholes remain that undermine their efficacy (Duggan, 2016). Recommendations include tightening these loopholes and improving mental health assessments during the purchase process (Kellermann & Rivara, 2017).

PowerPoint Presentation Guidelines

Ensure that the PowerPoint presentation consists of a minimum of 10 slides with bullet points summarizing the major arguments, accompanied by one of the specified formats for presenter notes, ensuring clarity and engagement (Schmidt, 2021).
