Answer:
encrypted file system (EFS)
Explanation:
The Encrypting File System (EFS) on windows is a Microsoft feature that help store sensitive file or information on a hard disk in an encrypted format so as to protect it from attackers or any other unauthorize individual. The EFS uses a combination symmetric key encryption and public key technology to protect the files, it is then encrypted with a symmetric algorithm known as DESX.
I believe the answer is <span>annual maintenance
</span><span>annual maintenance refers to the system maintenance that being done at a regular time period (most commonly done at least every 6 month)
This is really necessary in order to detect potential virus/malware that would compromise the information within your computer.</span>
Answer:
The best answer is letter D.
Explanation:
Downloading of files without your permission is a form of security threat and attack. You as unwilling victim will have your files and private information stolen.
One of the basics of internet security is to terminate any connection that you have in a network to stop the possible attack or threat. Worst case scenario is we can shut down our computers or devices or gadgets. But if we can just terminate the connection without performing a force shut down on the device, it is much better. This will give us more time to save what we are working on and to prevent losing important works or data. Terminating the connection from the network comes in various activities such as:
*Disconnect from the internet - this is one of the most effective method. As most of the attacks are coming from external threats such a hacking.
*Closing the browser - this could be helpful as well. Hackers are using browser to monitor their victims. And malwares and adwares are most active while we use browsers as they are embedded and using it to propagate to peform their activities.
*Disconnect from the local network - if you have closed the internet connection and any active software that you are working on presently and the downloading of files still persists, probably the attack comes from your local network. You must close any connection that you have within the local network.
*Deleting the recent files you have downloaded - You must delete any recent files that you just downloaded from your email or from the internet. There might be malware embedded in the file. Malwares are used by hackers to get in to their victims computer without them knowing it.
Then after terminating all the connections, you must call on your Instructor's attention. He / She is the authority in charge and must be aware of the situation.
Answer:
System of linear equations is solved below and explained in detail.
Explanation:
Part a:
M = [1 3 5 2; 2 -4 7 -3; 0 -4 -7 3; 5 -3 2 1];
c = [7; -3; -1; 0];
Part b:
The statement used for the solution of system of linear equation will be:
X = linsolve(M,c)
where X will give the values of x1, x2, x3, x4 respectively.
Part c:
The system is solved in matlab using above equation and the results are attached in a file.
The values for X are:
x1 = -2/7
x2 = 3/7
x3 = 4/7
x4 = 11/7
