Q181. CORRECT TEXT - (Topic 2)
Compliance with company policy requires a quarterly review of firewall rules. A new administrator is asked to conduct this review on the internal firewall sitting between several Internal networks. The intent of this firewall is to make traffic more restrictive. Given the following information answer the questions below:
User Subnet: 192.168.1.0/24 Server Subnet: 192.168.2.0/24 Finance Subnet:192.168.3.0/24
Instructions: To perform the necessary tasks, please modify the DST port, Protocol, Action, and/or Rule Order columns. Firewall ACLs are read from the top down
Task 1) An administrator added a rule to allow their machine terminal server access to the server subnet. This rule is not working. Identify the rule and correct this issue.
Task 2) All web servers have been changed to communicate solely over SSL. Modify the appropriate rule to allow communications.
Task 3) An administrator added a rule to block access to the SQL server from anywhere on the network. This rule is not working. Identify and correct this issue.
Task 4) Other than allowing all hosts to do network time and SSL, modify a rule to ensure that no other traffic is allowed.
Answer: Please look into the explanation for the solution to this question.
Q182. - (Topic 5)
An administrator is trying to categorize the security impact of a database server in the case of a security event. There are three databases on the server.
Current Financial Data = High level of damage if data is disclosed. Moderate damage if the system goes offline
Archived Financial Data = No need for the database to be online. Low damage for integrity loss
Public Website Data = Low damage if the site goes down. Moderate damage if the data is corrupted
Given these security categorizations of each database, which of the following is the aggregate security categorization of the database server?
A. Database server = {(Confidentiality HIGH),(Integrity High),(Availability High)}
B. Database server = {(Confidentiality HIGH),(Integrity Moderate),(Availability Moderate)}
C. Database server = {(Confidentiality HIGH),(Integrity Moderate),(Availability Low)}
D. Database server = {(Confidentiality Moderate),(Integrity Moderate),(Availability Moderate)}
Answer: B
Q183. - (Topic 3)
At 10:35 a.m. a malicious user was able to obtain a valid authentication token which allowed read/write access to the backend database of a financial company. At 10:45 a.m. the security administrator received multiple alerts from the company’s statistical anomaly-based IDS about a company database administrator performing unusual transactions. At
10:55 a.m. the security administrator resets the database administrator’s password.
At 11:00 a.m. the security administrator is still receiving alerts from the IDS about unusual transactions from the same user. Which of the following is MOST likely the cause of the alerts?
A. The IDS logs are compromised.
B. The new password was compromised.
C. An input validation error has occurred.
D. A race condition has occurred.
Answer: D
Q184. - (Topic 3)
A security administrator must implement a SCADA style network overlay to ensure secure remote management of all network management and infrastructure devices. Which of the following BEST describes the rationale behind this architecture?
A. A physically isolated network that allows for secure metric collection.
B. A physically isolated network with inband management that uses two factor authentication.
C. A logically isolated network with inband management that uses secure two factor authentication.
D. An isolated network that provides secure out-of-band remote management.
Answer: D
Q185. - (Topic 5)
An IT administrator has been tasked with implementing an appliance-based web proxy server to control external content accessed by internal staff. Concerned with the threat of corporate data leakage via web-based email, the IT administrator wants to decrypt all outbound HTTPS sessions and pass the decrypted content to an ICAP server for inspection by the corporate DLP software. Which of the following is BEST at protecting the internal certificates used in the decryption process?
A. NIPS
B. HSM
C. UTM
D. HIDS
E. WAF
F. SIEM
Answer: B
Q186. - (Topic 4)
The Information Security Officer (ISO) is reviewing a summary of the findings from the last COOP tabletop exercise. The Chief Information Officer (CIO) wants to determine which additional controls must be implemented to reduce the risk of an extended customer service outage due to the VoIP system being unavailable. Which of the following BEST describes the scenario presented and the document the ISO is reviewing?
A. The ISO is evaluating the business implications of a recent telephone system failure within the BIA.
B. The ISO is investigating the impact of a possible downtime of the messaging system within the RA.
C. The ISO is calculating the budget adjustment needed to ensure audio/video system redundancy within the RFQ.
D. The ISO is assessing the effect of a simulated downtime involving the telecommunication system within the AAR.
Answer: D
Q187. - (Topic 4)
The security administrator is reviewing the business continuity plan which consists of virtual infrastructures at corporate headquarters and at the backup site. The administrator is concerned that the VLAN used to perform live migrations of virtual machines to the backup site is across the network provider’s MPLS network. This is a concern due to which of the following?
A. The hypervisor virtual switches only support Q-in-Q VLANS, not MPLS. This may cause live migrations to the backup site to fail.
B. VLANs are not compatible with MPLS, which may cause intermittent failures while performing live migrations virtual machines during a disaster.
C. Passwords are stored unencrypted in memory, which are then transported across the MPLS network.
D. Transport encryption is being used during the live migration of virtual machines which will impact the performance of the MPLS network.
Answer: C
