EAP-TTLS

43
Q

This server is UDP-based and it authenticates servers such as VPN servers, Remote Access Servers (RAS) servers, and 802.1x authenticating switch. This server could be used to check any remote access policies and verify that authentication was allowed by contacting the domain controller.

A

RADIUS Server

44
Q

These clients could be VPN servers, RAS servers, and the 802.1x authentication switch. Each of these clients needs a private key that is sometimes known as the session key or shared secret to join the RADIUS environment.

RADIUS authentication uses UDP port 1812

RADIUS accounting uses UDP port 1813

A

TACACS+

47
Q

Allows someone working remotely, either from a hotel room or home, to connect securely through the internet to the corporate network.

A

Virtual Private Network (VPN)

48
Q

This is a legacy protocol that pre-dated the VPN. This client used modems and a dial-up network using telephone lines. It was very restricted in speed.

A

Remote Access Services (RAS)

49
Q

There are numerous methods of authentication used by VPN or RAS:

  • Password Authentication Protocol (PAP)
  • Challenge Handshake Authentication Protocol (CHAP)
  • MS CHAP/MSCHAP version 2
A

Authentication for VPN/RAS

50
Q

This authentication method for a VPN or RAS should be avoided at all costs as the passwords are transmitted as clear text and can easily captured.

A

Password Authentication Protocol (PAP)

51
Q

This authentication method for a RAS server is done with a four-stage process:

  1. Client makes connection request to RAS
  2. RAS replies with challenge that is a random string.
  3. Client uses password as encryption key to encrypt challenge.
  4. RAS encrypts the original challenge with a password stored for the user. If both values match, the client logs in.
A

Challenge Handshake Authentication Protocol (CHAP)

52
Q

This is Microsoft’s version of MS CHAP. This is the newer version of MS CHAP and can be sued by both VPN and RAS.

A

MS CHAP/MSCHAP version 2

53
Q

This is a solution that helps protect the privilege accounts within a domain, preventing attacks such as pass the hash, pass the ticket, and privilege escalation. This gives visibility in terms of who is using privilege accounts and what tasks they are being used for.

A

Privilege Access Management (PAM)

54
Q

This is a remote forest that has a very high level of security.

A

bastion forest

55
Q

Gives the admin just enough privileges to carry out a certain task.

A

Just Enough Administration (JEA)

56
Q

Manages the users in groups. These store objects such as users and computers as x500 objects. These objects form what is called a distinguished name and are organized and stored by the _____. It is comprised of three different objects, DC (Domain), Organization Unit (OU), and CN(anything else). ____ is the active directory storeman responsible for storing the X500 objects.

A

Lightweight Directory Access Protocol(LDAP)

57
Q

This is the Microsoft authentication protocol introduced with the release of Windows Server 2000. It is the only authentication protocol that uses tickets, Updated Sequence Numbers, and is time stamped. If ____ authentication fails, this is normally down to the user’s computer or device clock being out of sync with the domain controller by 5 minutes or more.

A

Kerberos

58
Q

This is the process for Kerberos for obtaining your service tickets. This is where the user sends their credentials to a domain controller that starts the authentication process and, when it has been confirmed, it will send back a service ticket that has a 10 hour lifespan.

A

Ticket Granting Ticket (TGT)

59
Q

This can be placed on your LAN to keep the domain computers and servers in sync with each other.

A

Network Time Protocol (NTP)

60
Q

This is used to prove who the user is. It exchanges their service ticket for a session ticket. The server then allows them access to the resources.

A

Service Ticket

61
Q

This provides a single sign-on as the user needs to log in only once. It then uses the service ticket to prove who they are, and a session ticket is returned

A

Single Sign-On/Mutual Authentication

62
Q

This is a legacy authentication protocol that stores passwords using the MD4 hash that is very easy to crack. It is susceptible to the pass-the-hash attack. Kerberos prevents the pass-the-hash attack as it uses an encrypted database.

A

NT Lan Manager (NTLM)

63
Q

This is where you have a parent domain and maybe one or more child domains that trust one another so long as the conditions allow it: these are called trees. For example, between the parent domain and each child domain is a two-way transitive trust, where resources can be shared two ways. Since the parent domain trusts both child A and Child B, it can be said that Child A and Child B transitively trust each other as long as admin for each allow it.

A

Transitive trust

64
Q

A term used for a domain; it could be a parent or a child domain.

A

trees

65
Q

TIP

You need to remember that Kerberos is the only authentication protocol that uses tickets. It also prevents replay attacks as it uses USN numbers and timestamps. It can also prevent pass-the-hash attacks.

A

TIP

66
Q

TIP

When the exam mentions a third-party authentication, this can only mean federation services. Federation services require cookies to be enabled.

A

TIP

67
Q

This kind of service is used when two different companies want to authenticate between each other when they participate in a joint venture. The companies don’t want to merge but rather keep their identity and have their own management in place. These are known as third-parties. Each company has their own directory database and normally only has access to their respective domain, but with this type of trust, they can use each others’ domains as long as they have alternative credentials.

A

Federation Services

68
Q

These are extended attributes used by their directory services. They are, in addition to the basic attributes, comprising of the following:

Employee ID
Email Address

A

User-Extended Attributes

69
Q

it is a XML-based authentication, which is used to pass the extended attribute credentials between company A and Company B in a federation service setup.

A

Security Assertion Mark-up Language (SAML)

70
Q

Mr. Red from Company A wants access to limited resources from Company B so he contacts them through a web browser and Company B asks him for his Employee ID and password.

Company B now uses the SAML to pass authentication details of Mr. Red to Company A. Mr. Red’s domain controller confirms that they are correct then Company B sends out a certificate to Mr. Red’s laptop. This certificate is used next time for authentication. They could alternatively use cookies.

A

Federation Services - Authentication and Federation Services - Exchange of Extended Attributes

71
Q

TIP

When the exams mentions authentication using extended attributes, this can only mean federation services. Cookies used for authentication would also be federation services.

A

TIP

72
Q

This is an open source federation service product that uses SAML authentication. It would be used for small federation service environment. This can also use cookies alternatively.

A

Shibboleth

73
Q

This is used in a domain environment. This is where someone logs into the domain and then can access several resources. such as the file or email server, without needing to input their credentials again. Federation services and Kerberos is a good example of ____.

A

Single Sign-on (SSO)

74
Q

Provides authorization to enable third-party applications to obtain limited access to a web service.

A

77
Q

Released with Windows 10, it uses an infrared camera making it better than regular cameras as they can have trouble with lighting.

A

Windows Hello

78
Q

It accepts unauthorized users and allows them to gain access. This is known as a Type ll error. Unauthorized users are allowed; look for the middle letter as an A.

A

False Acceptance Rate (FAR)

79
Q

It is where legitimate users who should gain access are rejected and cannot get in. This is known as a Type l error. Authorized users are rejected; look for the middle letter as an R.

A

False Rejection Rate (FRR)

80
Q

TIP

When looking at FAR or FRR, remember to look at the middle letter. Authorized users are rejected, the middle letter in FRR is R for reject. Unauthorized users are allowed so we look for the middle letter being A therefore we get FAR. Remember Authorized that starts with A does not belong to FAR that has an A as the middle letter. A does not select A.

A

Tip

81
Q

This is where the FAR and FRR are equal. If you are going to purchase a biometric system, you need a system that has a low CER.

A

Crossover Error Rate (CER)

82
Q

With a biometric system, you would want one with a low efficacy rate. This can be measured by looking at the CER point. You need a device with a low efficacy rate and a CER of less than 5%.

A

Efficacy Rates

83
Q

Could be more than two different factors; it just means multiple factors.

Q

This is made easy by the use of proximity cards, while guards on reception can also control access to the company. We can apply multi-factor authentication by using smart card authentication.

A

On-Premises Authentication

90
Q

This method should adopt a zero-trust model, where every connection is deemed to be a hacker as we cannot see who is logging. We could then use conditional statements to prove who is the person logging in, by using if-then statements. The three areas of conditional access are Signal, Decision, and Enforcement.

A

In The Cloud Authentication

91
Q

This could be user or group, location, device, calculated risk, and the application that needs to be accessed.

A
