Remote maintenance of the system is necessary, but it also becomes a "gateway" for ransomware attacks... a new idea to physically seal it off.

Remote maintenance of systems: While VPNs have been criticized and ZTNA (Zero Trust Network Access) is recommended, are you aware that there is a more robust foundation that can provide stronger protection? It has become difficult to balance intrusion prevention with rapid and efficient maintenance. Are you under the illusion that everything is fine just because ZTNA exists if VPNs are not viable? Connecting directly to applications remotely carries various risks beyond just access rights. We provide a mechanism to address those risks. High security using OWCD: Remote Desktop. Our application separates standard Windows communications and routes them through different paths while inserting OWCD, effectively blocking unauthorized access to the source side. This is an extremely effective method to add "upper layer defense" to existing environments. Our product offers overwhelming defense capabilities that "physically block" both external intrusions and internal leaks. It can be handled even by those who are not IT-savvy, integrating "peace of mind in connectivity" with a "protection mechanism," making it a security solution that should truly be chosen. When combined with other security measures, it enables multi-layered defense, minimizing potential damage in case of an incident. For inquiries, please visit our website via the link below ⤵.

basic information

Recent attacks target every entry point, including email, web, social media, VPN devices, and remote desktops. In particular, remote maintenance uses multiple pathways, making it difficult to implement more than the minimum measures such as strengthening authentication for externally exposed lines and updating VPN devices, resulting in inadequate defenses. If this vulnerability is left unaddressed, security enhancements will never catch up. Zero Trust is a security measure based on the premise of connectivity, and its significance greatly diminishes if the authentication server is not placed internally. Is it located externally? Perhaps in the cloud? Therefore, we strongly recommend our defense solution that combines OWCD. This allows you to add a robust defense layer that completely separates bidirectional communication performed by your existing remote control software into "one direction at a time." This enables multi-layered defense and significantly improves safety. Furthermore, by dedicating a specific PC for each service provider on the operation side and managing access, the defense capability is greatly enhanced. The required bandwidth varies depending on image quality and operation frequency, so we will select the optimal OWCD core and propose the most effective configuration. This will serve as a decisive factor in elevating the safety of your existing environment. For inquiries, please visit our website above.

Applications/Examples of results

OWCD can be used anywhere as long as it is a suitable place to restrict communication in one direction. This system is utilized in areas such as: - Maintenance of various devices within the server room - Remote maintenance of production equipment PLCs - Remote operation of surveillance camera systems. Of course, bidirectional data flows (such as Syslog, equipment operation information, and image output) can also be utilized when unnecessary. OWCD serves as a robust boundary on the network and is used in various situations. Its application in core systems, critical infrastructure, and government agencies is quietly expanding! The key to current cyber resilience measures is minimizing damage through multilayered defense and ensuring rapid recovery through established restoration procedures. Micro-segmentation is also perfectly compatible with the zero-trust framework, allowing for strong protection of core systems, including: - Protection of critical core equipment - Safeguarding backup data - Prevention of misuse of communication lines. We utilize multilayered protection daily to firmly safeguard these essential systems. For inquiries, please visit our company website above.
