X-Content-Type-Options
X-Content-Type-Options: nosniff is an HTTP header that instructs browsers not to "MIME sniff" a response and to respect declared content types.
If your glossary serves user-uploaded assets, code samples, or generated files, correct content typing + nosniff reduces risk.
Explanation
MIME sniffing can cause browsers to interpret content as executable scripts when it shouldn't be, enabling certain attack paths.
Marketing Relevance
If your glossary serves user-uploaded assets, code samples, or generated files, correct content typing + nosniff reduces risk.
Example
A malicious file uploaded as "text/plain" could be interpreted as script in some contexts without nosniff; the header reduces that risk.
Common Pitfalls
Incorrect content-type handling, serving uploads from the same domain without isolation, and missing consistent header configuration.
