Question 20

A company’s web filter is configured to scan the URL for strings and deny access when matches are found. Which of the following search strings should an analyst employ to prohibit access to non-encrypted websites?

    Correct Answer: B

    To prohibit access to non-encrypted websites, the analyst should employ the search string 'http://'. Non-encrypted websites use the HTTP protocol, which is identifiable by the 'http://' prefix in the URL, while encrypted websites use HTTPS, identifiable by 'https://'. By blocking the 'http://' string, the web filter will deny access to all non-encrypted websites effectively.

Discussion
SHADTECH123Option: B

Blocking the string "http://" is the best way to prohibit access to non-encrypted websites. Non-encrypted websites use HTTP, while encrypted websites use HTTPS. This ensures only non-encrypted traffic is blocked without affecting encrypted websites. A. encryption=off: Not a consistent identifier for non-encrypted websites. C. www.*.com: Too broad, blocks both encrypted and non-encrypted websites. D. :443: Indicates HTTPS traffic, blocking it would deny access to encrypted websites.

MehsotopesOption: B

http:// is an insecure protocol running on port 80 that uses unencrypted traceable data for communication on uncertified, & unprotected websites. It is indicated that you are on one of these insecure websites by a warning, or lack of padlock in your web search URL.
