Secure Drop is an open-source platform designed for secure and anonymous file transfer and communication between sources and journalists. It utilizes a combination of the Tor network protocol and encryption to ensure source identity protection and data transmission security. This article outlines the steps required to set up and manage a Secure Drop server.
Hardware and Network Environment Configuration
The first step is hardware preparation. Secure Drop requires at least two physical servers: one for the Secure Drop Application Server (SVS) and another for the Secure Drop Monitor Server (MVS). It is recommended to use dedicated hardware to enhance security and reduce the risk of information leakage.
- SVS will host the web interface and database for storing encrypted files and messages.
- MVS is used for monitoring and logging, facilitating communication between the server and end-users via Tor.
Both servers should be interconnected with a secure firewall that restricts access only to necessary IP addresses and services.
Software Installation and Configuration
Secure Drop requires a Linux operating system, ideally Debian or Ubuntu, for its well-known compatibility and security features. The installation involves several steps:
-
Tor Installation: Tor must be installed on both servers to ensure anonymous communication. Tor is used to generate a .onion address for your Secure Drop server, allowing users to access it without revealing their physical location or IP address.
-
Secure Drop Setup: After installing Tor, download and install the Secure Drop software from the official repository. During installation, you will be prompted to configure configuration files, including setting up encryption keys for each user.
-
Firewall and Network Rule Configuration: Properly configuring the firewall and network rules is critically important to restrict access only to necessary services and to ensure that communication between SVS and MVS is encrypted.
Security Measures and Maintenance
Security measures are crucial for protecting user anonymity and data integrity. This includes:
- Regular software and operating system updates to ensure protection against known security threats.
- Using strong encryption keys and securely storing them offline.
- Monitoring logs and network traffic to detect suspicious activity.
Configuring and managing a Secure Drop server requires careful preparation and knowledge of network security. Proper configuration of hardware, software, and security measures ensures source identity protection and the security of sensitive data. With the increasing need to protect whistleblowers and secure communication in the digital age, Secure Drop is a valuable tool for organizations dedicated to investigative journalism and privacy protection.
