Check the slides “OS Security II,” pg. 4-8. You are to implement a Dictionary Attack with and without Password Salt program in Python.

If you are not familiar with measuring execution time in Python, see the following website:

https://stackoverflow.com/questions/1557571/how-do-i-get-time-of-a-python-programs-execution

See the following steps.

1. Accept a user password of length N as keyboard input to your program. You can determine your own length N.

2. Compute the hash of the password from step 1.

Your hash function H() is simply the checksum. (See Assignment 2)

3. Now you become an attacker and try to find the password of length N.

Try every combination of length N password and for each combination, compute the hash and compare to the hash of the password from step 2.

Measure execution time.

4. Now let’s reinforce our password using the password salt. Accept an arbitrary non-negative integer number as keyboard input to your program.

5. Compute the hash of the concatenated password salt and password from step 4 and step 1. To compute the password salt portion of the checksum, you can treat the entire password salt as EITHER a single integer OR multiple one-byte integers.

6. Now you become an attacker and try to find the concatenated password salt and password.

Try every combination of an arbitrary non-negative integer number and length N password and for each combination, compute the hash and compare to the hash from step 5.

Measure execution time.

NOTE: your program should have separate functions for the checksum and the two dictionary attacks with and without the password salt by the attacker.

Answer the following question:

SQL is a pervasive querying language. While there is one primary SQL dialect that all SQL RDBMS implementations must support, and that’s ANSI SQL, each database platform comes out with its own context. Each of these dialects has its own  DDL (Data Definition Language). DML (Data Manipulation Language). and DQL (Data Query Language). Other than for marketing purposes (to sell the product as unique), what is the value of creating a new variation of a SQL dialect. 

Provide an example of one SQL dialect as part of your write-up.

Background: Kamehameha Institute is an organization that provides educational offerings to non-traditional students. The organization has tailored its unique educational offerings into the groups shown in Table 1 below:

Table 1. Kamehameha Educational Offerings.

GroupOfferingKamehameha BrandedFocused on the general public/provides services directly to its studentsCo-BrandedProvides the same services as Kamehameha Branded but resold by a third party and labeled as “…. Kamehameha Strong”White Label BrandedWhile the service offering is the same, these services are labeled solely with the third parties’ information

The State of Hawai’i regulates the educational sector, driving the need to ensure Kamehameha follows the State’s strict security and regulatory requirements. Kamehameha’s leadership is also very concerned with the threat posed by the online theft of their unique intellectual property. Additionally, the number of Hawai’ian entities breached by threat actors is on the rise. Thus, security, privacy, and compliance are all important considerations for the Kamehameha network architecture.

Your boss, the Kamehameha Institute’s Chief Operating Officer (COO) has tasked you to design a network infrastructure for three facilities located in the Hawaiian Islands of Honolulu, Hilo, and Lihue. The COO stipulated that you must separate the three group offerings in Table 1 and provide for strengthened defenses to protect Kamehameha’s cultural heritage. After meeting with the COO, the two of you drafted the following set of requirements for your network design:

· Each of the facilities has three floors:

· The first and second floor of each building requires 150 network connections each

· The third floor of each building houses a data center and requires 75 network connections

· The Honolulu location requires additional network connections for failover purposes

· The Hilo location will be the primary data center and house redundant database servers

· The Lihue location will serve as a failover data center and house the primary web servers (including the primary application and primary database servers)

· A constant connection between the three locations, carrying at least 75 Mbps of data

· All servers at all locations must have redundancy

· Protection from intrusions is required and should be documented

· A plan to verify security and failover measures is required

· Submission: Using the free tool, daw.io available at https://draw.io (no sign-in or registration required), create a network diagram (drawing) specific to the organization that encompasses the three facilities and also depicts ant necessary interconnections. Figure 1 shows the draw.io ‘new network diagram’ dialog window:

Figure 1. Draw.io New File Dialog Showing the Network Diagramming Templates

Your diagram should include enough detail to show the topology interconnections. The viewer should be able to understand the Kamehameha Institute’s network environment and be able to implement the architecture you develop. Ensure that you properly cite any external sources.

One of the keys to producing a viable network diagram is labeling the objects consistently and descriptively. Think about what you would want to know about a network device if you logged into it with little prior information. Consider location, floor number, or other pertinent information. At a minimum, include the following elements:

· IMPORTANT: Your network diagram must include an identifying label (e.g., callout box) that includes your class and section, assignment title, your name, and the date. Edit the items in italics. Your assignment will not be accepted if this element is missing:

· Any necessary hardware

· Site-to-Site (WAN) connections (e.g., leased line connectivity, satellite, etc.)

· Annotate the following values for each of the Sites:

· Network ID

· Useable Range

· Subnet Mask

· CIDR Value

· Broadcast Address

· All devices require hostnames complying with the following naming conventions:

· Routers: Rx; where x is the site number incremented by a value of 1 for each router

· Switches: Sx; where x is the site number incremented by a value of 1 for each switch

· Servers: SRVx where x is the server number incremented by a value of 1 for each server

· For each site router, implement a private ip addressing scheme using a range suitable for corporate infrastructure and include the following:

· management vlan

· production vlan
