What are the types of security mechanism in information security?
There are various types of security mechanism which are as follows −Physical Security − Physical security define limiting access to key network resources by maintaining the resources behind a locked door and secured from natural and human-made disasters.Physical security can secure a network from unintended exploitation of network equipment by untrained faculty and contractors. It can also secure the network from hackers, competitors, and terrorists walking in off the street and changing equipment configurations.It is based on the level of protection, physical security can secure a network from terrorist and biohazard events, such as bombs, radioactive spills, etc. Physical security ...
Read MoreWhat are True Random Number Generation?
A true random number generator (TRNG) uses a nondeterministic source to make randomness. Most function by measuring unpredictable natural processes, including pulse detectors of ionizing radiation activities, gas discharge tubes, and leaky capacitors.Intel has developed a commercially accessible chip that samples thermal noise by developing the voltage measured across undriven resistors. TRNG generates a true random number and is produced generally by hardware method.Because the random number produced by TRNG is complex to predict because TRNG is generated based on a physical source that is complex to forecast a random value. Hence, the random number produced from TRNG is a ...
Read MoreWhat are the principle of Symmetric Cipher in Information Security?
A symmetric cipher is one that uses the similar key for encryption and decryption. The use of a symmetric cipher presents the well-known challenge of how to share the secret key between the parties fast, as an unauthorized party to the communication can prevent it and eavesdrop on future communication.There are various principles of Symmetric Cipher which are as follows −Plaintext − This is the authentic intelligible message or information that is full into the algorithm as input.Encryption algorithm − The encryption algorithm implements several substitutions and conversion on the plaintext.Secret key − The secret key is also input to ...
Read MoreWhat is the comparison between Authentication and Authorization in Information Security?
AuthenticationAuthentication is the procedure of providing that an individual is the person that they claim to be. This contains matching a person’s claimed identity asserted through a credential (such as an ID card or unique ID number) against one or more authentication factors that are destined to that credential.Authentication is about validating the credentials such as User Name/User ID and password to verify the identity. The system decides whether it can what it can say and it is using the credentials.In public and private networks, the system authenticates the user identity through login passwords. Authentication is usually completed by a ...
Read MoreWhat is Authorization in Information Security?
Authorization is the procedure of permitting someone to do something. It defines it an approach to check if the user has permission to need a resource or not. It can represent that what data and information one user can access.It is also called as AuthZ. The authorization generally works with authentication so that the system can understand who is accessing the information. Authorization is a security structure used to decide user/client privileges or access levels associated with system resources, such as computer programs, files, services, data and application features.Authorization is generally preceded by authentication for customer identity verification. System administrators ...
Read MoreWhat are the types of Cryptosystems in information security?
There are various types of cryptosystem which are as follows −Private Key cryptosystems − Symmetric encryption is also known as private-key encryption or secret-key encryption. It contains using the similar key for encryption and decryption. Encryption contains using an operation (an algorithm) to the data to be encrypted using the private key to create them meaningless.The main disadvantage of a secret-key cryptosystem is associated to the exchange of keys. Symmetric encryption depends on the swap of a secret (keys).Public-key cryptosystems − Public-key cryptosystems is also known as asymmetric cryptography. It is a type of cryptographic algorithms which needed two separate ...
Read MoreWhat is the need of Authentication in Information Security?
Authentication is the procedure of checking if a user or entity or device is who claims to be. In another terms, it is a set of verification and Identification. Authentication falls into three elements which are as follows −The knowledge factors − Something the user understand such as a password, pass phrase, or personal identification number (PIN), challenge response, design.The ownership factors − Something the user has wrist band, ID card, security token, cell phone with included hardware token, software token, or cell phone holding a software token.The inherence factors − Something the user is or does such as fingerprint, ...
Read MoreWhat are the Authentication methods in Information Security?
There are various method of Authentication which are as follows −Biometrics − Biometrics is a term that defines the measuring unique individual characteristics including the retina, the iris, fingerprints or even the face. Today, the concept is usually used by most people to define a method for protecting computers and saved data requiring a user to endure a scan of the body part used for identification.While several systems need a fingerprint or retinal scan as a user password, systems that are serious about security frequently need a password and a biometric scan before open the computer or device.There are some ...
Read MoreWhat is the difference between Two-factor Authentication and Multi-factor Authentication in Information Security?
Two-factor AuthenticationTwo-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 different types of information.It is a security procedure that cross-verifies users with two multiple forms of identification, most generally knowledge of an email address and authentication of control of a mobile phone.2FA is frequently employed in online banking websites, social media platforms and ecommerce sites as an approach to harden access controls to the more responsive location of a web application including admin panels or areas that store credit ...
Read MoreWhat are the types of multi-factor authentication?
Multi-factor authentication (MFA) is a security procedure that needed users to respond to requests to test their identities before they can access networks or other online software. MFA can use knowledge, control of physical elements, or geographic or network areas to prove integrity.Multi-factor authentication is a layered method to protecting information and applications where a system needed a user to present a set of two or more credentials to test a user’s identity for login.MFA operates by requiring more verification data is known as “authentication factors. It can ensure that digital users are who they say they are. These elements ...
