NEW QUESTION # 204
An internal security assessor identified large gaps in a company's IT asset inventory system during a monthly asset review. The assessor is aware of an external audit that is underway. In an effort to avoid external findings, the assessor chooses not to report the gaps in the inventory system. Which of the following legal considerations is the assessor directly violating?
- A. Due care
- B. Due process
- C. Due notice
- D. Due diligence
Answer: A
Explanation:
Given the scenario where the security assessor identified gaps but chose not to report them, the primary violation is with "due diligence." The assessor did not complete the due diligence process by withholding critical information. If the assessor had identified the gaps (due diligence) and then did nothing to address or rectify those gaps (despite knowing about them), that would be a violation of "due care." Due diligence: refers to the investigations and research conducted before taking an action.
Due care: is about taking the necessary steps to mitigate the risks and threats that have been identified through due diligence.
Due diligence need to happen before dual care. In the given scenario, the internal security assessor never did the duel diligence part.

NEW QUESTION # 207
A company wants to improve the security of its web applications that are running on in-house servers A risk assessment has been performed and the following capabilities are desired:
* Terminate SSL connections at a central location
* Manage both authentication and authorization for incoming and outgoing web service calls
* Advertise the web service API
* Implement DLP and anti-malware features
Which of the following technologies will be the BEST option?
- A. XML gateway
- B. API gateway
- C. WAF
- D. ESB gateway
Answer: B
Explanation:
An API gateway is a device or software that acts as an intermediary between clients and servers that provide web services through application programming interfaces (APIs). An API gateway can provide various functions such as:
Terminating SSL connections at a central location, reducing the overhead on the backend servers and simplifying certificate management Managing both authentication and authorization for incoming and outgoing web service calls, enforcing security policies and access control Advertising the web service API, providing documentation and discovery features for developers and consumers Implementing DLP and anti-malware features, preventing data leakage and malicious code injection A web application firewall (WAF) is a device or software that filters and blocks malicious web traffic from reaching an application. A WAF can provide some protection for web services, but it does not provide all the functions of an API gateway. An XML gateway is a device or software that validates, transforms, and routes XML messages between clients and servers that provide web services. An XML gateway can provide some functions of an API gateway, but it is limited to XML-based web services and does not support other formats such as JSON. An enterprise service bus (ESB) gateway is a device or software that integrates and orchestrates multiple web services into a single service or application. An ESB gateway can provide some functions of an API gateway, but it is more focused on business logic and workflow rather than security and performance.

A company has decided that only administrators are permitted to use PowerShell on their Windows computers. Which of the following is the BEST way for an administrator to implement this decision?
- A. Uninstall PowerSheII from all workstations.
- B. Block PowerSheII via HIDS.
- C. Configure user settings in Group Policy.
- D. Monitor the Application and Services Logs group within Windows Event Log.
- E. Provide user education and training.
Answer: C
Explanation:
Configuring user settings in Group Policy is the best way for an administrator to implement the decision to restrict PowerShell access to only administrators. Group Policy is a feature of Windows that allows administrators to manage and enforce settings for users and computers in a domain. By using Group Policy, an administrator can create a policy that blocks or disables PowerShell for all users except for a particular group, such as administrators. This policy can be applied to all computers in the domain or to specific organizational units. This method is more effective and manageable than uninstalling PowerShell, monitoring event logs, providing user education, or blocking PowerShell via HIDS. Verified References:

Answer: D
Explanation:
If on VPN concentrator goes down due to a zero day threat, having a redundant VPN concentrator of a different vendor should keep you going.
NEW QUESTION # 216
A security operations center analyst is investigating anomalous activity between a database server and an unknown external IP address and gathered the following data:
- dbadmin last logged in at 7:30 a.m. and logged out at 8:05 a.m.
- A persistent TCP/6667 connection to the external address was
established at 7:55 a.m. The connection is still active.
- Other than bytes transferred to keep the connection alive, only a few kilobytes of data transfer every hour since the start of the connection.
- A sample outbound request payload from PCAP showed the ASCII content:
"JOIN #community".
Which of the following is the MOST likely root cause?
- A. A SQL injection was used to exfiltrate data from the database server.
- B. The dbadmin user is consulting the community for help via Internet Relay Chat.
- C. The system has been hijacked for cryptocurrency mining.
- D. A botnet Trojan is installed on the database server.
Answer: D
Explanation:
A botnet Trojan is installed on the database server as evidenced by the persistent TCP/6667 connection established to an external address at 7:55 a.m. This type of connection is commonly associated with botnets using Internet Relay Chat (IRC) channels for command and control (C&C) purposes. The ASCII content "JOIN #community" captured in outbound requests from PCAP further supports this conclusion, indicating active participation in an IRC channel. The dbadmin's log-in and log-out times (7:30 a.m. to 8:05 a.m.) suggest that the Trojan or malware was likely activated after the user logged out, exploiting the server's resources for unauthorized external communication.

Answer: C
NEW QUESTION # 218
Given the following information:
* Firewall rules: Existing rules do not account for Web Server C's IP address (10.2.0.92).
* Application A Security Group: Inbound rules and outbound rules are insufficient for the new server.
The security team wants to minimize the firewall rule set by avoiding specific host rules whenever possible.
Which of the following actions must be taken to resolve the issue and meet the security team's requirements?
- A. Change the security group inbound rules to include the new IP address of Web Server C
- B. Alter the security group outbound rules to be more restrictive
- C. Modify the firewall rules to include the new IP address of Web Server C
- D. Reconfigure Web Server C to 10.2.0.62
Answer: C
Explanation:
Comprehensive and Detailed Step by Step Explanation:
* The issue stems from Web Server C's new IP (10.2.0.92) not being included in the firewall rules.
* To resolve the issue, modify the firewall rules to include the new IP range (e.g., 10.2.0.0/26) rather than adding a specific host rule, ensuring scalability and simplicity.
* Changing inbound or outbound security group rules would still miss the underlying issue of omitted IPs.
* Reconfiguring the IP is unnecessary when updating firewall rules is sufficient.

NEW QUESTION # 221
A systems administrator at a web-hosting provider has been tasked with renewing the public certificates of all customer sites. Which of the following would BEST support multiple domain names while minimizing the amount of certificates needed?
- A. CRL
- B. CA
- C. OCSP
- D. SAN
Answer: D
Explanation:
The administrator should use SAN certificates to support multiple domain names while minimizing the amount of certificates needed. SAN stands for Subject Alternative Name, which is an extension of a certificate that allows it to include multiple fully-qualified domain names (FQDNs) within the same certificate. For example, a SAN certificate can secure www.example.com, www.example.net, and mail.example.org with one certificate. SAN certificates can reduce the cost and complexity of managing multiple certificates for different domains. SAN certificates can also support wildcard domains, such as *.example.com, which can cover any subdomain under that domain.
