An analyst investigated a website and produced the following:
Starting Nmap 7.92 ( https://nmap.org ) at 2022-07-21 10:21 CDT
Nmap scan report for insecure.org (45.33.49.119)
Host is up (0.054s latency).
rDNS record for 45.33.49.119: ack.nmap.org
Not shown: 95 filtered tcp ports (no-response)
PORT STATE SERVICE VERSION

Which of the following syntaxes did the analyst use to discover the application versions on this vulnerable website?
Which of the following will most likely cause severe issues with authentication and logging?
Time synchronization issues can cause severe problems with authentication and logging. If system clocks are not properly synchronized, it can lead to discrepancies in log timestamps, making it difficult to correlate events across different systems. Additionally, time-related discrepancies can affect authentication mechanisms that rely on time-based tokens, such as those used in multifactor authentication, leading to failures and security gaps.
During a tabletop exercise, engineers discovered that an ICS could not be updated due to hardware versioning incompatibility. Which of the following is the most likely cause of this issue?
The most likely cause of the issue where an ICS (Industrial Control System) could not be updated due to hardware versioning incompatibility is a legacy system. Legacy systems often have outdated hardware and software that may not be compatible with modern updates and patches. This can pose significant challenges in maintaining security and operational efficiency.
Which of the following best describes the key goal of the containment stage of an incident response process?
The key goal of the containment stage in an incident response process is to limit further damage from occurring. This involves taking immediate steps to isolate the affected systems or network segments to prevent the spread of the incident and mitigate its impact. Containment strategies can be short-term, to quickly stop the incident, or long-term, to prepare for the eradication and recovery phases.
