What are the objectives of MCQ on network security? Identification, Authentication, and Access control are the purposes of web security. In this article, we will know some questions about network protection and why it is important.
MCQ on Network Security
Network security is a set of technologies that protects the usability and integrity of a company’s infrastructure by preventing entry. Also, proliferation within a network of a wide variety of potential threats.
While in the case of other systems (for example, the telephone), it is possible to execute access control using a form. If the user identifies himself as a legitimate user, he can receive an access code that must be at the time of logon.
The identification form is also used to identify users when they wish to change their passwords or modify other information in their accounts.
Identification
When a user connects to the network, he must identify himself to the system. It is necessary, therefore, to determine the identity of each user and to store the name of each user in some form, usually in a database. A user can be the user name or by an id number.
Authentication
After a user has identified himself, he must prove who he is. If he can prove that he is who he purports to be, then access will be granted. The authentication process involves proving identity by providing some secret information that only a specific person would know.
Access control
The final step in the process of granting access to an individual is in the control of the resources that are available to that individual by the network.
Computer Network
Network security can be summarized as a set of policies, procedures, and tools to protect confidentiality. Also, the integrity of data is over a computer network.
The goals of these policies, procedures, and tools include the prevention of intrusions and the protection of data from unauthorized access or modification. Network security should be in terms of two principles: confidentiality and integrity.
Confidentiality is the property that data is not disclosed to unauthorized persons or processes. Data confidentiality is a primary concern in networks whose environment includes untrusted parties who may attempt to intercept or modify data in transit. Also, data confidentiality is a prime concern for networks in military and intelligence applications.
The integrity of data sent across a network is a primary concern for networks where the environment. Also, network security must address the integrity of critical files stored on servers as well as the integrity of the files that are over the network.
The third requirement for any computer network is user authentication. User authentication ensures that only authorized persons can use the network’s resources. Also, it prevents intruders from masquerading as legitimate users to gain access to sensitive information.
MCQ on Network Security: Purpose
The purpose of network security is to ensure that only authorized persons can access a company’s information. Also, to make sure that no unauthorized person can enter a network and gain access to confidential information.
There are two common types of networks: local-area networks (LANs) and wide-area networks (WANs). A LAN is a network that covers a relatively small area, such as one building or a campus.
Conclusion
Network security is a process of protection, usually in the form of a system. Also, a set of policies monitors the security of a computer network and protects it from various attacks.
