Which one of the following statements about cryptographic hash algorithms is not true? O The same message to cryptographic hash functions always generate the same hash value. Given a message m1, it is difficulty to find a different message m2, so that hash(m1) = hash(m2) O It is impossible to find two messages m1 and m2, such as hash(m1) = hash(m2) O A small change to a message will result in a big change of hash value.

Answer 1

The statement that is not true about cryptographic hash algorithms is "It is impossible to find two messages m1 and m2, such as hash(m1) = hash(m2)."

Cryptographic hash algorithms are designed to map input data of arbitrary size to a fixed-size output, called a hash value or digest. The hash function should possess certain properties, including the property of collision resistance, which means it should be computationally infeasible to find two different messages that produce the same hash value.

The first statement, "The same message to cryptographic hash functions always generate the same hash value," is true. The same input will always yield the same output hash value.

The third statement, "A small change to a message will result in a big change of hash value," is also true. Even a minor modification in the input message will produce a significantly different hash value due to the avalanche effect of cryptographic hash functions.

However, the second statement, "It is impossible to find two messages m1 and m2, such as hash(m1) = hash(m2)," is false. While highly unlikely, the existence of hash collisions is theoretically possible due to the pigeonhole principle. However, a secure hash function should make finding such collisions computationally infeasible.

which line of java code correctly creates a two-dimensional array of integers containing six total locations (holds six numbers)?

Answers

To create a two-dimensional array of integers in Java containing six total locations, you can use the following line of code:
```java
int[][] myArray = new int[2][3];
```

This code creates a 2D array named "myArray" with 2 rows and 3 columns, resulting in a total of 6 locations to hold integer values.

An "array" is a data structure used to store a collection of elements of the same type. It provides a way to organize and access data in a sequential manner. Arrays are commonly used in programming and can be found in various programming languages. In an array, elements are stored in contiguous memory locations, and each element is identified by its index. The index represents the position of an element within the array, starting from 0 for the first element and incrementing by one for each subsequent element.

Sansa has moved the only Linux server within VPC1 to the Linux-only VPC15. The remaining servers in VPC1 all run Windows Server. Which of the following should she do on the firewall for VPC1?
Disable port 22
HIDS
private key

Answers

Sansa should disable port 22 on the firewall for VPC1 since it is used for SSH access to Linux servers, and the Linux server has already been moved to VPC15. She may also consider implementing a Host-based Intrusion Detection System (HIDS) to enhance the security of the remaining Windows servers in VPC1.

Explanation:

Disable port 22: Port 22 is the default port used for SSH access to Linux servers. Since Sansa has moved the only Linux server to VPC15, there is no need to keep port 22 open on the firewall for VPC1. Disabling port 22 enhances security by closing this entry point for SSH connections.

Implement HIDS: Host-based Intrusion Detection System (HIDS) monitors and analyzes activity on a specific host or server. Sansa should consider implementing a HIDS for the remaining Windows servers in VPC1. HIDS can help detect and respond to potential security incidents, providing an additional layer of security for the Windows servers.

Private key: In this scenario, the private key is not directly relevant to the firewall configuration. A private key is typically used for secure authentication to a server, but it does not affect the firewall rules. It is more related to the authentication mechanism and access control for the server itself.

By disabling port 22 and implementing a HIDS, Sansa can enhance the security of VPC1. Disabling unused ports reduces the attack surface, and a HIDS provides monitoring and detection capabilities to identify potential intrusions or suspicious activities on the remaining Windows servers. It is important to regularly review and update firewall rules and security measures to ensure the ongoing protection of the VPC environment.

2. indicate the entries in the tables when the following procedures are executed. addblock(f2,b) addblock(f1,b) delblock(f1,5) delblock(f3,7) addblock(f1,b)

Answers

To answer this question, we need to understand what is meant by the terms "entries" and "tables". In the context of databases, a table is a collection of data that is organized into rows and columns, while an entry refers to a single record or piece of data within that table.

The first two procedures are adding blocks to files f2 and f1 respectively, with the block data represented by the variable "b". When these procedures are executed, new entries will be added to the corresponding tables for each file. The exact structure of these tables is not provided, so we cannot say exactly what these entries will look like.

The next two procedures are deleting blocks from files f1 and f3. In the case of delblock(f1,5), we are removing the 5th block from file f1. This means that the corresponding entry for that block will be deleted from the table for file f1. Similarly, for delblock(f3,7), we are deleting the 7th block from file f3, which will remove the corresponding entry from the table for file f3.

Finally, we have another addblock procedure for file f1, which will add a new entry to the table for that file. Again, we don't know the exact structure of the table, so we can't say what this entry will look like.

In summary, the entries in the tables will change as follows:

- For file f2, a new entry will be added representing the block data provided by variable "b".
- For file f1, two new entries will be added representing the block data provided by variable "b". The 5th block will be removed (and its corresponding entry deleted), and then a new entry will be added for the new block data provided by variable "b".
- For file f3, the 7th block will be removed (and its corresponding entry deleted).


A step by step analysis is given below :


1. addblock(f2, b):
This procedure adds a new block (b) to the table associated with f2. As a result, the entries in the table for f2 will now include block b.

2. addblock(f1, b):
This procedure adds block b to the table associated with f1. Now, both tables for f1 and f2 have an entry for block b.

3. delblock(f1, 5):
This procedure removes block 5 from the table associated with f1. After this step, the entries in the table for f1 will no longer include block 5, but the other entries will remain unchanged.

4. delblock(f3, 7):
This procedure removes block 7 from the table associated with f3. Consequently, the entries in the table for f3 will no longer include block 7, but the other entries will stay the same.

5. addblock(f1, b):
Since block b is already present in the table for f1 (from step 2), this procedure does not change the entries in the table for f1.

In summary, after executing all the procedures, the tables will have the following entries:
- Table for f1: includes block b and any other existing entries, but not block 5.
- Table for f2: includes block b and any other existing entries.
- Table for f3: does not include block 7 and remains with its other existing entries.

This initializes count of digits to 0

count = 0

The following loop is repeated while number is not 0
