Answer:
The answer is by using a covert channel like shared memory objects such as files, directories,messages, etc since both the user and the sender of the document are on same network of the company.
Explanation:
The Bell LaPadula MultiLevel Security model was a security policy developed by Bell and LaPadula in 1973 in response to a security issue raised by the US Air Force regarding file-sharing mainframe computers . Actually, many people with networked systems have realized by early 1970s that the protection purportedly offered by many commercial operating systems was poor, and wa not getting better any time soon. This was observed when it was noticed that as one operating system error was fixed, some other vulnerability would be discovered. There was also the constant worry that various unskilled users would discover loopholes in the operating system during usage and use them to their own advantage.
Information release may take place via shared memory objects such as files, directories, messages, and so on. Thus, a Trojan Horse acting on behalf of a user could release user-private information using legitimate operating system requests. Although developers can build various mechanisms within an operating system to restrict the activity of programs (and Trojan Horses) operating on behalf of a user , there is no general way, short of implementing nondiscretionary policy models, to restrict the activity of such programs. Thus, given that discretionary models cannot prevent the release of sensitive information through legitimate program activity, it is not meaningful to consider how these programs might release information illicitly by using covert channels.
For example, for someone with higher integrity level (SECRET) to send an accounts payable application to a user, if the untrusted accounts payable application contains a Trojan Horse, the Trojan Horse program could send a (legal) message to the said user process running at a lower integrity level (CONFIDENTIAL), thereby initiating the use of a covert channel. In this covert channel, the Trojan Horse is the receiver of (illegal) lower integrity-level input and the user process is the sender of this input.
Answer:
- def getLargest(number_list):
- new_list = []
-
- for x in number_list:
- if(isinstance(x, int)):
- new_list.append(x)
-
- largest = max(new_list)
-
- return largest
Explanation:
Firstly, create a function <em>getLargest()</em> that take one input parameter, <em>number_list</em>.
The function will filter out the float type number from the list by using <em>isinstance() </em>method (Line 5). This method will check if a current x value is an integer. If so, the x value will be added to <em>new_list</em>.
Next, use Python built-in <em>max</em> function to get the largest integer from the <em>new_list </em>and return it as output.
Answer:
C) the online catalog.
Explanation:
An online library catalog describes the periodicals, videotapes, and books as it is the electronic bibliographic database. This evolved from the printed source, the library card catalog. Hence, this clarifies that its C. the correct option.
However, LexisNexis is the unit that gives computer-assisted research CALR and business research as well as risk management services. So through this, you can get the legal and journalistic documents.
And the stack or the book stack which is referred to as the library building block is for book storage. And the library of Congress Subject Headings is active since 1898 and holds the catalog materials which are being collected by the Library of Congress, and they do not keep track of periodicals. And the BizMiner is for financial reports.
Hence, the correct answer is the C) the online catalog.
Answer:
ssume that,
Maximum “students” count can be 10.
*Driver Class*
*Solution class*
import java.util.*;
class Student {
private String name;
private int rollNo;
public String getName() {}
public void setName(String name) {}
public int getRollNo() {}
public void setRollNo(int rollNo) {}
};
class ClassRoom {
private int i;
private Student[] students;
public void addStudent(String name, int rollNo) {}
public Student[] getAllStudents() {}
};
