Removable media control tool (RMCT)
RMCT is a software or software-hardware tool for controlling the use of USB drives, external disks and other removable media in order to prevent data leaks and malware infection.

What is a removable media control tool
Removable media control tool (RMCT) is a software or software-hardware solution designed to manage access to removable machine information media (USB flash drives, external HDD/SSD, optical discs, memory cards). RMCT provides control over the use of I/O interfaces, connection of external devices and specific removable media.
RMCT is a mandatory protection element for systems processing personal data (152-FZ) and operating at critical information infrastructure (CII) facilities, since removable media is one of the main channels of data leaks and malware distribution.
According to FSTEC, more than 30% of information security incidents are related to the use of removable media. This makes RMCT a critically important protection element for any organization.
Main functions of RMCT
A removable media control tool performs the following functions:
- Access control — allowing or prohibiting the use of removable media for different users.
- Connection control — registration of all attempts to connect external devices.
- Data encryption — automatic encryption of information written to removable media.
- Audit and logging — registration of all media operations for SIEM systems.
- Antivirus check — scanning connected media together with antivirus software.
RMCT is often a module of larger protection systems, such as DLP systems, and integrates with cryptographic protection tools (CIPF) to ensure data encryption on removable media.
Key advantages of RMCT
The implementation of RMCT gives organizations the following possibilities:
- Prevention of data leaks — blocking the copying of confidential information to external media.
- Protection from malware — preventing system infection through infected USB devices.
- Insider control — tracking employee actions with external media.
- Compliance with regulatory requirements — fulfilling the requirements of 152-FZ and 187-FZ.
The choice and implementation of RMCT requires a professional assessment of the infrastructure. The design service will help determine the optimal architecture and integrate RMCT with existing protection tools.
RMCT architecture
RMCT can be implemented in two main architectures: agent-based and network. The agent-based architecture involves installing a software agent on each workstation, which controls the connection of removable media and transfers data to a central management server.
The network architecture involves installing network sensors that analyze traffic and control the use of external devices at the network level. The hybrid architecture combines both approaches and provides maximum protection.
Frequently asked questions
Why is a removable media control tool needed?
RMCT prevents the leak of confidential data through USB flash drives and external disks, blocks system infection through infected media and makes it possible to track employee actions with external devices. This is a mandatory requirement for systems working with personal data and at CII facilities.
What functions does RMCT perform?
RMCT performs the functions of access control to media, control of their connection, automatic encryption of data on removable devices, audit of all operations and antivirus check of connected media together with antivirus software.
How does RMCT integrate with DLP systems?
RMCT is often a module of DLP systems, providing control at the level of connected devices. DLP receives from RMCT data about all operations with external media and can apply security policies, for example, block the writing of certain file types or encrypt all data.
What Russian RMCT solutions are available?
In Russia, RMCT is often part of comprehensive solutions: Secret Net Studio, Dallas Lock, Solar Dozor. Most of them are certified by FSTEC and included in the Register of Domestic Software.
Can RMCT be bypassed?
RMCT uses several levels of protection: control at the OS level, hardware identification of devices, encryption and audit. To bypass RMCT, it is necessary to have administrative rights or use specialized methods that can also be detected by the system. Regular updates and audits help minimize bypass risks.
How does RMCT affect system performance?
Modern RMCTs use optimized algorithms and practically do not affect system performance. The impact on the speed of operation is less than 1-2% even with active use of external media.
Is the use of RMCT mandatory for small business?
For small business, the use of RMCT is not mandatory, unless the company works with personal data or is a CII facility. However, to protect trade secrets and prevent leaks, it is recommended to use RMCT as part of a comprehensive security system.
