Use securityheaders.com to perform a security header scan for 'example.com'. Identify the overall security grade, list any headers explicitly marked as 'Missing', and determine the value of the 'Strict-Transport-Security' header if present. If 'Strict-Transport-Security' is not present, state that.
Navigate to securityheaders.com. Enter 'example.com' into the 'enter address here' input field (id: 33). Click the submit button (id: 34) to initiate the scan. Once the scan results are displayed, identify the overall security grade. List all headers explicitly identified under the 'Missing Headers' section. Locate the 'Strict-Transport-Security' header in the 'Raw Headers' section and extract its value, or note its absence.
Successfully initiate a scan for 'example.com'. State the overall security grade received for 'example.com'. List all security headers identified as 'Missing' in the scan results. State the value of the 'Strict-Transport-Security' header if present, or explicitly state that it is not present.
