This is the core feature of any DCIM. It creates a centralized database for every piece of hardware in the data center.
"Full" directories found via search engines are often traps. Cybercriminals may rename malicious scripts as image files (e.g., image.jpg.exe ) to infect the computers of curious users.
If a directory must remain public for some reason but you do not want search engines to find it, place a robots.txt file in the root directory containing: User-agent: * Disallow: /private/ Disallow: /DCIM/ Use code with caution.
