About this tag
The ot network hardening tag covers discussions on securing operational technology (OT) networks, with a focus on industrial control systems like Schneider Modicon PLCs. Content highlights the need to update firmware, harden webservers, and reduce exposure to mitigate vulnerabilities such as cross-site scripting. Recurring themes include firmware updates, webserver hardening, and reducing attack surface in OT environments. These practices are critical for protecting industrial networks from authenticated attacks that could compromise controller web interfaces.
