To deal with presence of multiple orphaned accounts as a security administrator in an organization, the user accounts should be disabled.
<h3>What is orphaned accounts?</h3>
The orphaned accounts are the accounts which do not have any valid business owner but provide the access to the services and corporate systems. One best way to deal with such account is to disable the user account.
Steps to deal with orphaned accounts-
- Using the automated provisioning and deprovisioning can save the
- Control the accounts with micro-certification.
- Regular check of account to prevent the hidden access risk.
You have been hired as a security administrator. While analyzing your organization's personnel policies, you notice the presence of multiple orphaned accounts.
In such case, one should disable these accounts.
Thus, to deal with presence of multiple orphaned accounts as a security administrator in an organization, the user accounts should be disabled.

Answer:
Option (B) i.e., Sensor is the correct answer.
Explanation:
The following option is true because the sensor is both types of device that is input as well as output that gather information or data from the environment directly.
Option A i.e., Audio input is incorrect because the audio input that device which records the voice, music or audio in the form of data.
Option C i.e., Trackball is incorrect because trackball record the movement of the ball in which direction we move that ball, in that direction the cursor is moving.
Option D i.e., Touch Screen is incorrect because it is the device that works by the touch of the human being such as touchpad, mobile phones, etc.
Answer:
Encryption method security:-
- Encryption method representing each alphabetic character as an integer between 0 and 25.
- Now, apply RSA algorithm for each integer is not an efficient secure encryption method.
Explanation:
- Let consider alphabetic characters set {A, B... Z} .
- Each alphabetic character forms a set of message block values M={0,1,2...,25).
- From encryption method the corresponding cipher text block value C = {0e mod n,1e mod n, 2e mod n,..., 25e mod n}.
- Then, compute the cipher text with knowledge of Bob's public key;
- If the public key is generated, then possibility to decrypt the cipher text to plain text.
- The generated public key is easily calculated by everyone and security is lost.
- Therefore, the encryption method is not secure.
Encryption method is not secure, Most efficient attack against this method:-
- Now, compute the encryption message with the function Me mod n for all the possible values of M.
- This is the most efficient attack against the scheme in encryption method.
- Then, create a look-up table with cipher text as an index to the corresponding plain text as a value for appropriate location in the table.
