QUESTION 590When considering a vendor-specific vulnerability in critical industrial control systems which of the following techniques supports availability? A.    Deploying identical application firewalls at the borderB.    Incorporating diversity into redundant designC.    Enforcing application white lists on the support workstationsD.    Ensuring the systems' anti-virus definitions are up-to-date Answer: BExplanation:If you know there is a vulnerability that is specific to one vendor, you can improve availability by implementing multiple systems that include at least one system from a different vendor and so is not affected by the vulnerability. QUESTION 591Jane, a security administrator, needs to implement a secure wireless authentication method that uses a remote RADIUS server for authentication.Which of the following is an authentication method Jane should use? A.    WPA2-PSKB.    WEP-PSKC.    CCMPD.    LEAP Answer: DExplanation:A RADIUS server is a server with a database of user accounts and passwords used as a central authentication database for users requiring network access. The Lightweight Extensible Authentication Protocol (LEAP) is a proprietary wireless LAN authentication method developed by Cisco Systems. Important features of LEAP are dynamic WEP keys and mutual authentication (between a wireless client and a RADIUS server). LEAP allows for clients to reauthenticate frequently; upon each successful authentication, the clients acquire a new WEP key (with the hope that the WEP keys don't live long enough to be cracked). LEAP may be configured to use TKIP instead of dynamic WEP. QUESTION 592Ann, a security administrator, wishes to replace their RADIUS authentication with a more secure protocol, which can utilize EAP. Which of the following would BEST fit her objective? A.    CHAPB.    SAMLC.    KerberosD.    Diameter Answer: DExplanation:Diameter is an authentication, authorization, and accounting protocol that replaces the RADIUS protocol. Diameter Applications extend the base protocol by including new commands and/or attributes, such as those for use of the Extensible Authentication Protocol (EAP). QUESTION 593Which of the following is an authentication service that uses UDP as a transport medium? A.    TACACS+B.    LDAPC.    KerberosD.    RADIUS Answer: DExplanation: RADIUS runs in the application layer and makes use of UDP as transport. QUESTION 594Pete, a security auditor, has detected clear text passwords between the RADIUS server and the authenticator. Which of the following is configured in the RADIUS server and what technologies should the authentication protocol be changed to? A.    PAP, MSCHAPv2B.    CHAP, PAPC.    MSCHAPv2, NTLMv2D.    NTLM, NTLMv2 Answer: AExplanation:PAP transmits the username and password to the authentication server in plain text. MSCHAPv2 is utilized as an authentication option for RADIUS servers that are used for Wi-Fi security using the WPA-Enterprise protocol. QUESTION 595RADIUS provides which of the following? A.    Authentication, Authorization, AvailabilityB.    Authentication, Authorization, AuditingC.    Authentication, Accounting, AuditingD.    Authentication, Authorization, Accounting Answer: DExplanation:The Remote Authentication Dial In User Service (RADIUS) networking protocol offers centralized Authentication, Authorization, and Accounting (AAA) management for users who make use of a network service. It is for this reason that A, B, and C: are incorrect. QUESTION 596Which of the following types of security services are used to support authentication for remote users and devices? A.    BiometricsB.    HSMC.    RADIUSD.    TACACS Answer: CExplanation:RADIUS authentication phase takes place when a network client connects to a network access server (NAS) and provides authentication credentials. The NAS will then make use of the authentication credentials to issue a RADIUS authentication request to the RADIUS server, which will then exchange RADIUS authentication messages with the NAS. QUESTION 597Which of the following relies on the use of shared secrets to protect communication? A.    RADIUSB.    KerberosC.    PKID.    LDAP Answer: AExplanation:Obfuscated passwords are transmitted by the RADIUS protocol via a shared secret and the MD5 hashing algorithm. QUESTION 598Ann has taken over as the new head of the IT department. One of her first assignments was to implement AAA in preparation for the company's new telecommuting policy. When she takes inventory of the organizations existing network infrastructure, she makes note that it is a mix of several different vendors. Ann knows she needs a method of secure centralized access to the company's network resources. Which of the following is the BEST service for Ann to implement? A.    RADIUSB.    LDAPC.    SAMLD.    TACACS+ Answer: AExplanation:The Remote Authentication Dial In User Service (RADIUS) networking protocol offers centralized Authentication, Authorization, and Accounting (AAA) management for users who make use of a network service. QUESTION 599Which of the following is mainly used for remote access into the network? A.    XTACACSB.    TACACS+C.    KerberosD.    RADIUS Answer: DExplanation:Most gateways that control access to the network have a RADIUS client component that communicates with the RADIUS server. Therefore, it can be inferred that RADIUS is primarily used for remote access. QUESTION 600A system administrator is using a packet sniffer to troubleshoot remote authentication. The administrator detects a device trying to communicate to TCP port 49. Which of the following authentication methods is MOST likely being attempted? A.    RADIUSB.    TACACS+C.    KerberosD.    LDAP Answer: BExplanation:TACACS makes use of TCP port 49 by default.
