Two-factor authentication (2FA) a type of multi-factor authentication (MFA). It is an approach of creating access to an online account or computer system that needed the user to support two multiple types of information.It is a security procedure that cross-verifies users with two several forms of identification, most frequently knowledge of an email address and authentication of ownership of a mobile phone.Two factor authentication has become an important information security tool because it mitigates the risk related to negotiated login credentials. If a password is hacked, guessed, or even estimated, 2FA avoids an attacker from gaining access without authorization by ... Read More

An authentication factor is a specific element of security credential that can be used to check the identity and authorization of a user trying to gain access, send connection, or request information from a secured network, system or software.Each authentication factor defines an element of security controls of the equal type. Within each element, security analysts can design or select a feature that fits their needs in terms of accessibility, cost, content of implementation, etc.It can be increasing the multiple authentication elements needed to access a system can create the login procedure more cumbersome, and can produce increased numbers of ...

There are various types of information security which are as follows −Antivirus and Antimalware Software − This software can be used for protecting against malware, which contains spyware, ransomware, Trojans, worms, and viruses. Malware can also become very hazardous as it can affect a network and then remain quiet for days or even weeks.This software manage this threat by searching for malware entry and regularly tracks files afterward to identify anomalies, delete malware, and fix the loss.Firewall Protection − A firewall acts as a defense barrier among the trusted internal networks and untrusted external networks including viruses, worms, Trojans, brute ...

Information security is also known as InfoSec. It covers the devices and processes that organizations use to secure data. This contains policy settings that avoid unauthorized people from accessing business or personal data.Information security protects responsive data from unauthorized activities, such as inspection, modification, recording, and some disruption or destruction.The main objective of information security is to provide the safety and privacy of critical information such as user account details, financial record or intellectual property.In information security, an organization can secure data and technology by responding, preventing, and recognizing internal and external threats. Information security methods are the responsibility of ... Read More

Authentication is the procedure of recognizing someone's identity by assuring that the person is the similar as what it is claiming for. It can be used by both server and client.The server uses authentication when someone needs to access the data, and the server required to understand who is accessing the data. The client uses it when it is need to understand that it is the same server that it claims to be.The authentication by the server is completed mostly by utilizing the username and password. There are some another method of authentication by the server can also be completed ... Read More

A process (or a device incorporating such a procedure) that is designed to identify, avoid, or retrieve from a security attack. The structure are divided into those that are performed in a definite protocol layer, including TCP or an software-layer protocol and those that are not definite to any specific protocol layer or security service. These structure are also called a pervasive security mechanisms.Pervasive security is supported by a set of physical interfaces and network interfaces to a service to a user contains creating by the user's client device network connectivity to the service, broadcasting by the service an identifier ...

A process (or a device compilation such a process) that is designed to identify, avoid, or restore from a security attack. The mechanisms are divided into those that are performed in a definite protocol layer, including TCP or an application-layer protocol. These mechanisms are known as specific security mechanisms.These can be integrated into the relevant protocol layer in order to support some of the OSI security services. There are some approaches for realizing security are as follows −Encipherment − This is the procedure of using numerical algorithms to change data into a form that is not freely intelligible. The transformation ... Read More

There are various services of information security which are as follows −Data Confidentiality − Confidentiality is the security of transmitted information from passive attacks. Regarding the content of an information transmission, there are multiple levels of protection can be recognized.The broadest service secure all user information transmitted among two users over a duration. For instance, when a TCP connection is install among two systems, this broad protection avoids the release of some user information transmitted over the TCP connection.It can identify modifications (insertion, deletion, and rerun) and attempt recovery. The limited forms of this service can also be described, such ... Read More

Attacks are defined as passive and active. A passive attack is an attempt to understand or create use of data from the system without influencing system resources; whereas an active attack is an attempt to change system resources or influence their operation.Passive Attacks − Passive attacks are in the feature of eavesdropping on, or observation of, transmissions. The objective of the opponent is to access data that is being transmitted. There are two method of passive attacks are release of message contents and traffic analysis.The release of message contents is simply learn. A telephone chat, an electronic mail message, and ...

The OSI security architecture provides the managers responsible for the security of an organization in describing the necessity for security. The OSI security architecture was introduced as an ‘international standard’ which allow the computer and communication dealer produce the products that have security characteristics depends on this architecture.The OSI security architecture has a structure description of services and structure for supporting security to the organization’s data. The OSI security architecture targets on security attacks, structure, and services.These can be represented concisely as follows −Security attack − Security attack is any action that deal the security of data owned by an ...
