An attacker has obtained the logon credentials for a regular user on your network. Which type of security threat exists if this
jarptica [38.1K]

Answer:

privilege escalation.

Explanation:

An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.

Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Hence, an access control list (ACL) primarily is composed of a set of permissions and operations associated with a user account or new technology file system (NTFS) file such as full control, read only, write, read and execute and modify.

In this scenario, an attacker or hacker was able to obtain the logon credentials for a regular user on your network. Thus, the type of security threat which exists if this user account is used by the attacker or hacker to perform administrative functions is privilege escalation.

Privilege escalation can be defined as a network or security threat which involves the exploitation of a design flaw, bug or unsecured configuration settings in a software program (application), operating system (OS), computer system, etc., so as to have an unauthorized access and gain more permissions, elevated rights or privileges that are normally protected from a user account or software program.

Hence, when an attacker or malicious user such as a hacker gains an unauthorized access to the privileges of another user account beyond what is intended or entitled to a user, it is known as privilege escalation.

Which of the following Python methods in scipy.stats submodule returns the P-value for performing a hypothesis test for the sign
ipn [44]

Answer:

Option B is the correct answer for the following question.

Explanation:

The following option is true because the pearsonr from scipy module is the method of the Python Programming Language in the submodule i.e., "scipy.stats" which print or return P-value for operating the hypothesis test for the value of correlation coefficient. So, that's why the following option is correct.

Contrast the performance of the three techniques for allocating disk blocks (contiguous, linked, and indexed) for both sequentia
Pie
The allocation methods define how the files are stored in the disk blocks.
There are three main disk space or file allocation methods:
1.Contiguous Allocation-in this scheme,each file occupies a set of blocks on the disk. For example if a file requires x blocks and is given a block y as the starting location,then the blocks assigned to the file be :x,y+1,y+2,......y+x-1.
This means that given the starting block address and the length of the file(in terms of blocks required) we can determine the blocks occupied by the file.
Advantages
-both the sequential and direct accesses are supported
-this is extremely fast since the number of seeks are minimal because of contiguous allocation of file blocks.
2.linked allocation-in this scheme,each file linked list of disk blocks which need not  be contiguous disk blocks can be scattered anywhere on the disk.
Advantages
it is very flexible in terms of file size.file size can be increased easily since the system does not have to look for a contiguous chunk 
of memory.
this method does not suffer from external fragmentation and it makes it relatively better in terms of memory utilization.
3.Indexed Allocation-in this scheme,a special block known as the index block contains the pointers to all the blocks occupied by a file.Each file has its own index block.the entry in the index block contains the disk address of the block
Advantages
it supports direct access to the blocks occupied by the file and therefore provides fast access to the file blocks
it overcomes the problem of external fragmentation.

What does it mean to design,<br> implement, and maintain computer<br> systems?
docker41 [41]

Answer:

Let's take an example of the embedded system, which is a perfect example of this question as a computer system. Suppose we want the embedded system to record the details related to soil of agricultural land. We will take an IoT device which will be a sensor that can register soil properties, and get connected to the computer system through the internet. And we design an embedded system that registers these values and then copy them like somewhere in DB space on Amazon cloud or Google cloud. And finally display on some LCD or a big projector, or whatever, and like we design. Thus we have designed, and now when we install this on agriculture land, we implement it, and since check regular for correct performance, we maintain this embedded or a mini-computer system as well. This is what design, implement and maintain computer systems mean.
