Which security property is assured by symmetric encryption?

Answers

Answer 1

The security property assured by symmetric encryption is "confidentiality." Symmetric encryption ensures that the data being transmitted or stored is kept confidential, meaning that only authorized parties with the correct shared key can access the information.

Symmetric encryption is a type of encryption that uses the same key for both encryption and decryption of data. The symmetric key is used to scramble the original plaintext data into ciphertext, which is unreadable without the key. When the recipient receives the ciphertext, they use the same key to decrypt it back into the original plaintext data.

Confidentiality is a security property that ensures that data is kept secret and protected from unauthorized disclosure. With symmetric encryption, confidentiality is assured because the symmetric key is required to decrypt the ciphertext and access the original plaintext data. As long as the key is kept secret and secure, the confidentiality of the data is maintained.

Convert a BST to a Binary Tree such that sum of all greater keys is added to every key

Answers

In order to convert a BST to a Binary Tree such that the sum of all greater keys is added to every key, we need to perform a reverse in-order traversal of the tree.

During the traversal, we keep track of a running sum of all the keys we've seen so far. At each node, we add the running sum to the current node's key, and update the running sum to be the sum of the current node's key and all the keys greater than it in the BST.

In other words, for each node, we first visit its right subtree, then update the node's key with the running sum, and finally visit its left subtree.

By doing this for every node in the tree, we end up with a Binary Tree where the sum of all greater keys has been added to every key. This is because during the traversal, we've essentially visited all the nodes in descending order of key values, and added the sum of all greater keys to each node's key as we went along.

The EMPLOYEE_ID column in the EMPLOYEES table corresponds to the EMPLOYEE_ID column of the ORDERS table. The EMPLOYEE_ID column in the ORDERS table contains null values for rows that you need to display. Which type of join should you use to display the data?

Answers

Use a LEFT OUTER JOIN to display data from both tables, including any non-matching rows from the left table with null values for the columns in the right table.

To display the data from the EMPLOYEES and ORDERS tables where the EMPLOYEE_ID column in the EMPLOYEES table corresponds to the EMPLOYEE_ID column in the ORDERS table, including the rows in the ORDERS table where the EMPLOYEE_ID column contains null values, you should use a LEFT OUTER JOIN. A LEFT OUTER JOIN returns all the rows from the left table (EMPLOYEES) and matching rows from the right table (ORDERS), and includes any non-matching rows from the left table with null values for the columns in the right table. This means that all rows from the EMPLOYEES table will be included in the result set, even if there is no corresponding row in the ORDERS table with a matching EMPLOYEE_ID value. By using a LEFT OUTER JOIN, you can display the data from both tables while ensuring that all data from the EMPLOYEES table is included, regardless of whether there is a corresponding row in the ORDERS table.

Answers

A. Bank of the organization is the most likely to face a regulatory requirement to conduct vulnerability scans.

Any organization can gain from doing vulnerability checks, but banks are more likely to be subject to regulatory regulations. The financial sector is heavily regulated, and several regulatory organizations, like the Federal Financial Institutions Examination Council (FFIEC), mandate that banks do routine vulnerability scans and penetration tests in order to discover and reduce possible security threats. Because they manage a lot of sensitive financial data and transactions, banks are valuable targets for hackers. Regular vulnerability scans can help banks find any possible system vulnerabilities and fix them before attackers can use them. Although legislative requirements for conducting vulnerability assessments and penetration tests may also apply to other businesses, such as healthcare and government, the financial sector is often thought to have some of the strictest security rules.

suppose that logical and physical addresses in a paging system are 32-bits and that pages are 1k bytes with each frame number also being a 32-bit integer. what is the maximum size in bytes of the page table for each process

Answers

The maximum size in bytes of the page table for each process is 8MB multiplied by the size of the page table entry.

In a paging system, the page table is a data structure that maps logical addresses to physical addresses. The size of the page table is determined by the number of pages in the system and the size of each page. In this case, we are given that the pages are 1k bytes and the logical and physical addresses are 32-bits.

To calculate the maximum size in bytes of the page table, we need to consider how many pages can be addressed using 32-bit addresses.

Since each page is 1k bytes, we can address [tex]2^{20}[/tex] pages (since [tex]2^{10}[/tex] = 1k).

This means that we need 20 bits to represent each page number in the page table.

Since each process has its own page table, the maximum size of the page table for each process can be calculated as follows:

The page table entry size = size of physical address + additional bits for flags and other information
Since the physical address is 32 bits, the page table entry size is at least 32 bits + additional bits
The number of entries in the page table = number of pages in the system ([tex]2^{20}[/tex])

Therefore, the maximum size of the page table for each process is [tex]2^{20}[/tex] * (32 bits + additional bits) / 8 = 8MB * (32 bits + additional bits).


The additional bits may be used for flags or other information, such as permission bits for read, write, and execute access. The actual size of the page table may be smaller than this maximum size if not all pages in the system are being used by the process.

It is also possible that a firewall is blocking the response, but that is not the only explanation for the asterisk. Instead, it suggests that the traceroute packet may have been lost or dropped at that particular hop, but traffic may still be flowing through the network path successfully. Traceroute results with an asterisk () are generally considered inconclusive and may require further investigation to determine the cause of the lack of response.

Create the Atbash Cypher and use it to encrypt the following: security rules

hvxfirgbifovh
hvxfribighovh
hvofibgrifxvh
hvohvxfirgif

Answers

The Atbash Cipher is a simple substitution cipher where the first letter of the alphabet is swapped with the last, the second with the second to last, and so on.

Using this cipher, we can encrypt the phrase "security rules" by replacing each letter with its corresponding letter in the cipher:

s --> h
e --> v
c --> x
u --> i
r --> k
i --> v
t --> g
y --> r
 --> i
r --> k
u --> i
l --> o
e --> v
s --> h

The encrypted phrase is "hvxfirgbifovh".

Similarly, we can encrypt the other phrases using the Atbash Cipher:

- "hvxfirgbifovh" (security rules)
- "hvxfribighovh" (encryption method)
- "hvofibgrifxvh" (secret message)
- "hvohvxfirgif" (codebreaker)

Note that in the Atbash Cipher, spaces and punctuation are usually ignored and left unchanged.
