What entity is responsible for authenticating a user?
Local Security Authority. The Local Security Authority (LSA) is a protected system process that authenticates and logs users on to the local computer.
What defines user authentication as the process of verifying an identity claimed by or for a system entity?
RFC 2828 defines user authentication as: “The process of verifying an identity claimed by or for a system entity.” *Computed as the number of matches divided by the search size. The more words that need to be tested for a match, the lower the cost/benefit ratio.
Is a separate file from the user IDs where hashed passwords are kept?
3. A shadow password file is a separate file from the user IDs where hashed passwords are kept. 4. With the complex password policy a user is allowed to select their own password, but.
Which strategy is one in which the system periodically runs its own password cracker to find guessable passwords?
Reactive password checking
Which of the following is the most secure form of authentication?
What is Beyond Identity? Beyond Identity combines two of the strongest authenticators: biometrics and asymmetric keys. It eliminates the password and provides an extremely secure authentication since the user’s identity is only stored locally on the device and it cannot be moved.
Is the granting of a right or permission to a system entity to access a system resource?
Definition(s): The right or a permission that is granted to a system entity to access a system resource.
What is the difference between an access control list and a capability ticket?
What is the difference between an access control list and a capability ticket? Access control list lists the users and their permitted access rights. Capability ticket specifies authorized objects and their operations for a user. An object which is having a set of objects together with access rights.
Is the active entity that access an object?
A subject is an active entity that causes information to flow among objects or changes the system state. An object, also referred to as a resource, is a passive information system-related entity containing or receiving information.
What is based on the roles the users assume in a system rather than the user’s identity?
In contrast, RBAC is based on the roles that users assume in a system rather than the user’s identity. Typically, RBAC models define a role as a job function within an organization. RBAC systems assign access rights to roles instead of individual users.
What are the components of RBAC?
The components of RBAC such as role-permissions, user-role and role-role relationships make it simple to perform user assignments. A study by NIST has demonstrated that RBAC addresses many needs of commercial and government organizations.
Which one of the following attack involves an adversary repeating a previously captured user response?
Replay attacks
Is the traditional method of implementing access control?
DAC is the traditional method of implementing access control. based on comparing security labels (which indicate how sensitive or critical system resources are) with security clearances (which indicate system entities are eligible to access certain resources).
Which of the following is an authentication method?
Passwords, smart cards, digital certificates, Kerberos, and biometrics are among the many authentication methods currently employed.
What type of authentication is based on what the user has quizlet?
ANSWER: Multifactor authentication uses multiple types of authentication credentials, such as what a user knows and what a user has, whereas single-factor authentication uses only one type of authentication.
Which access control mechanism identifies a user of a system?
Authentication (who can log in) is actually a two step process consisting of identification & authentication. the means by which a user (subject) presents a specific identity (e.g. user id) to a system (object), and the process of verifying that identity.
What are the 3 different types of access rights?
The Three Types of Access Control Systems
- Discretionary Access Control (DAC)
- Managed Access Control (MAC)
- Role-Based Access Control (RBAC)
What are examples of logical access controls?
An easy-to-understand example of logical access controls is implementing access control lists to limit access to protocols used for remote administration. Remote administration is a fact of life for many large organizations.
What are access control techniques?
Access control identifies users by verifying various login credentials, which can include user names and passwords, PINs, biometric scans, and security tokens. Many access control systems also include multifactor authentication, a method that requires multiple authentication methods to verify a user’s identity.
What is the most common form of authentication used?
Passwords are the most common methods of authentication. Passwords can be in the form of a string of letters, numbers, or special characters.
What are the four major access control models?
Currently, there are four primary types of access control models: mandatory access control (MAC), role-based access control (RBAC), discretionary access control (DAC), and rule-based access control (RBAC).
