User-agent: * Disallow: /view/ Disallow: /cctv/ Disallow: *.shtml However, robots.txt is a polite request, not a security control. Move the web interface from port 80/443 to a non-standard high port (e.g., 23456). Rename /cctv/work/ to something unpredictable like /C8f92jA1/ . 4. Implement IP Whitelisting If possible, restrict access to the camera’s web interface to specific internal IPs or VPN subnets. 5. Use HTTP Headers to Prevent Indexing Add to your web server configuration:
X-Robots-Tag: noindex, nofollow Use tools like Shodan, Censys, or even Google’s own search with the site: operator to see what’s indexed. inurl view index shtml cctv work
| Operator/Keyword | Meaning | |------------------|---------| | inurl: | Google search operator that restricts results to pages where the keyword appears in the URL string. | | view | A common directory or script name for viewing content—often camera feeds or recorded footage. | | index.shtml | An SSI (Server Side Includes) file extension. .shtml files are dynamic HTML pages, frequently used in older CCTV/DVR web interfaces. | | cctv | Closed-circuit television. Filters results to surveillance-related systems. | | work | Often found in paths like /work/ , cctv_work , or as a parameter. May indicate working directories, test environments, or live operational panels. | User-agent: * Disallow: /view/ Disallow: /cctv/ Disallow: *
As the Internet of Things expands, surface-level vulnerabilities like these will persist. The only long-term solution is a culture of security awareness: default passwords must die, internal IPs must not be publicly routable, and every .shtml file should ask for a password before rendering a single frame of video.
