security explained

🌐 This page is also available in: Deutsch
Non-English support is best-effort. The English version is more complete.

We’re taking customers’ security and privacy pretty seriously. On that page, you can find the applied security measures and notes.

Measures

• firewall
• intrusion prevention
• ssh daemon hardening
• OS-level permissions (matrix components run under separate Linux user and group)
• docker containers hardening
• single source of truth (any modifications done to matrix components configurations will be wiped and replaced on each maintenance run)

Data access

What data can be accessed by etke.cc?

• any system file (because of the ssh access with sudo permissions)
• any plaintext (unencrypted) information (e.g unencrypted text messages from bridged chats)

What data can NOT be accessed by the etke.cc?

• encrypted data (encrypted messages, files, etc.)

Audit

How customers can check what is going on on their servers?

• /var/log/auth.log available by default (due to default OS log rotation policies, there may be files like /var/log/auth.log.1, /var/log/auth.log.2, … as well)
• The Linux Audit
• In 99.99% of all actions on the customers’ servers performed by the automation system, source code is available on gitlab.com/etke.cc
