A Chief Security Officer (CSO) has been unsuccessful in attempts to access the website for a potential partner (www.example.net)
Which of the following rules is preventing the CSO from accessing the site? Blocked sites: *.nonews.com, *.rumorhasit.net, *.mars?

A. B. C. D.C.
Based on the information provided, we can deduce that the CSO is trying to access a website that may be blocked by the organization's firewall rules. The potential partner's website address is www.example.net, and we are given a list of blocked sites: *.nonews.com, *.rumorhasit.net, and *.mars.
From the list of firewall rules provided, we need to determine which rule is preventing the CSO from accessing the www.example.net website.
Rule 1 denies any traffic from the inside network to any outside destination using the SMTP service. SMTP is typically used for email traffic, so it is unlikely that this rule is preventing access to a website.
Rule 2 denies any traffic from the inside network to any outside destination using the ping service. Ping is used to test network connectivity, and it is not typically used to access websites. Therefore, it is unlikely that this rule is preventing access to the website.
Rule 3 denies any traffic from the inside network to any outside destination that matches the list of blocked sites, using the HTTP or HTTPS service. This rule matches the pattern of the blocked sites, so it is possible that this rule is preventing the CSO from accessing the www.example.net website.
Rule 4 denies all traffic from any source to any destination using any service. This rule is very broad, and it would block all traffic, including legitimate traffic. It is unlikely that this rule is in place, as it would effectively shut down all network communication.
Based on this analysis, it is most likely that Rule 3 is preventing the CSO from accessing the www.example.net website. This rule is denying HTTP and HTTPS traffic to any destination that matches the list of blocked sites, which includes *.nonews.com, *.rumorhasit.net, and .mars. Since www.example.net is not explicitly listed, it is possible that it falls under the wildcard character () and is being blocked as a result.
