A new browser version has been deployed to all users at a company.
After the deployment, users report that they can no longer access the company's secure time-card system, which is hosted by a SaaS provider.
A technician investigates and discovers a security error is received upon opening the site.
If the browser is rolled back to the older version, the site is accessible again.
Which of the following is the MOST likely cause of the security error users are seeing?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
Based on the given scenario, the most likely cause of the security error users are seeing is option D - Unencrypted communications between the users and the application.
Here's why:
A new browser version has been deployed to all users at a company. This implies that there has been a change in the browser's security configuration, which could affect how it communicates with the SaaS provider's time-card system.
Users report that they can no longer access the company's secure time-card system, which is hosted by a SaaS provider. This suggests that the issue is specific to the time-card system and not a general problem with the SaaS provider's infrastructure.
A technician investigates and discovers a security error is received upon opening the site. This indicates that the browser is detecting a security issue with the time-card system.
If the browser is rolled back to the older version, the site is accessible again. This suggests that the issue is specific to the new browser version and not a problem with the time-card system itself.
Based on the above points, it is reasonable to assume that the new browser version has introduced a security feature that is not compatible with the SaaS provider's time-card system. Specifically, the security feature could be preventing unencrypted communication between the users and the application, which was previously allowed by the old browser version. This would explain why the site is accessible again when the browser is rolled back to the older version.
Option A is unlikely to be the cause of the issue because if the SSL certificate on the SaaS load balancers had expired, the issue would affect all users, not just those using the new browser version.
Option B is also unlikely because federation issues would affect all users and not just those using the new browser version.
Option C is also unlikely because obsolete security technologies on the SaaS servers would not affect the browser's ability to communicate with the time-card system.
