NEW QUESTION # 133
A company recently deployed a SIEM and began importing logs from a firewall, a file server, a domain controller a web server, and a laptop. A security analyst receives a series of SIEM alerts and prepares to respond. The following is the alert information:
Which of the following should the security analyst do FIRST?
- A. Shut down abc-usa-fw01; the remote access VPN vulnerability is exploited
- B. Disable the jdoe account, it is likely compromised
- C. Disable Administrator on abc-uaa-fsl, the local account is compromised
- D. Shut down the abc-usa-fsl server, a plaintext credential is being used
Answer: B
Explanation:
Explanation
Based on the SIEM alerts, the security analyst should first disable the jdoe account, as it is likely compromised by an attacker. The alerts show that the jdoe account successfully logged on to the abc-usa-fsl server, which is a file server, and then initiated SMB (445) traffic to the abc-web01 server, which is a web server. This indicates that the attacker may be trying to exfiltrate data from the file server to the web server. Disabling the jdoe account would help stop this unauthorized activity and prevent further damage.
Disabling Administrator on abc-usa-fsl, the local account is compromised, is not the first action to take, as it is not clear from the alerts if the local account is compromised or not. The alert shows that there was a successful logon event for Administrator on abc-usa-fsl, but it does not specify if it was a local or domain account, or if it was authorized or not. Moreover, disabling the local account would not stop the SMB traffic from jdoe to abc-web01.
Shutting down the abc-usa-fsl server, a plaintext credential is being used, is not the first action to take, as it is not clear from the alerts if a plaintext credential is being used or not. The alert shows that there was RDP (3389) traffic from abc-admin1-logon to abc-usa-fsl, but it does not specify if the credential was encrypted or not. Moreover, shutting down the file server would disrupt its normal operations and affect other users.
Shutting down abc-usa-fw01; the remote access VPN vulnerability is exploited, is not the first action to take, as it is not clear from the alerts if the remote access VPN vulnerability is exploited or not. The alert shows that there was FTP (21) traffic from abc-usa-dcl to abc-web01, but it does not specify if it was related to the VPN or not. Moreover, shutting down the firewall would expose the network to other threats and affect other services. References: What is SIEM? | Microsoft Security, What is a SIEM Alert? | Cofense
NEW QUESTION # 134
Based on a recent security audit, a company discovered the perimeter strategy is inadequate for its recent growth. To address this issue, the company is looking for a solution that includes the following requirements:
* Collapse of multiple network security technologies into a single footprint
* Support for multiple VPNs with different security contexts
* Support for application layer security (Layer 7 of the OSI Model)
Which of the following technologies would be the most appropriate solution given these requirements?
- A. NGFW
- B. NAT gateway
- C. Reverse proxy
- D. NIDS
Answer: A
Explanation:
A Next-Generation Firewall (NGFW) is the best solution to meet the company's needs. NGFWs combine multiple security functions, such as VPN support, intrusion prevention, application-layer (Layer 7) inspection, and more, into a single device, simplifying network security management while improving security coverage. NGFWs can support multiple VPNs with different security contexts, which is critical for the company's requirement. CASP+ emphasizes NGFWs for their ability to collapse multiple security technologies into one platform and offer application-layer security, addressing modern perimeter security needs.

NEW QUESTION # 143
Which of the following indicates when a company might not be viable after a disaster?
- A. Maximum tolerable downtime
- B. Recovery time objective
- C. Mean time to recovery
- D. Annual loss expectancy
Answer: A
Explanation:
The indicator that shows when a company might not be viable after a disaster is the maximum tolerable downtime (MTD). MTD is the maximum amount of time that a business process or function can be disrupted without causing unacceptable consequences for the organization. MTD is a key metric for business continuity planning and disaster recovery, as it helps determine the recovery time objective (RTO) and the recovery point objective (RPO) for each process or function. If the actual downtime exceeds the MTD, the organization may face severe losses, reputational damage, regulatory penalties, or even bankruptcy. Verified Reference:

* A vulnerability in a third-party horary was exploited by the hacker, resulting in the compromise of a local account.
* The hacker took advantage of the account's excessive privileges to access a data store and exfiltrate the data without detection.
Which of the following is the BEST solution to help prevent this type of attack from being successful in the future?
- A. User behavior analysis
- B. Dynamic analysis
- C. Software composition analysis
- D. Secure web gateway
- E. Web application firewall
Answer: E
Explanation:
A web application firewall (WAF) is a security device that inspects web application traffic and can detect and prevent malicious activity such as SQL injection, cross-site scripting, and malicious file uploads. This type of attack could have been prevented if a WAF was in place to monitor and block malicious traffic. Resources:

NEW QUESTION # 145
A security engineer has been informed by the firewall team that a specific Windows workstation is part of a command-and-control network. The only information the security engineer is receiving is that the traffic is occurring on a non-standard port (TCP 40322). Which of the following commands should the security engineer use FIRST to find the malicious process?
- A. tasklist
- B. netstar
- C. tcpdump
- D. traceroute
- E. ipconfig
Answer: B
Explanation:
Netstat is a command-line tool that can be used to find the malicious process that is using a specific port on a Windows workstation. Netstat displays active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table, IPv4 statistics (for the IP, ICMP, TCP, and UDP protocols), and IPv6 statistics (for the IPv6, ICMPv6, TCP over IPv6, and UDP over IPv6 protocols). To find the process that is using a specific port, such as TCP 40322, the security engineer can use the following command:
netstat -ano | findstr :40322
This command will filter the netstat output by the port number and show the process identifier (PID) of the process that is using that port. The security engineer can then use the task manager or another tool to identify and terminate the malicious process by its PID. Verified Reference:
