Cybersecurity: Hardening security on your SecureSync®
Customers frequently seek information and recommendations from Safran about hardening security, including general guidelines about available network security features, jamming and spoofing deterrence, bug fixes, and networking-related issues.
Sometimes they’re in search of specific practices for time servers and clients. Sometimes, because SecureSync® is part of critical infrastructure, they may not fully understand all the issues related to timing, such as Global navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also jamming/spoofing, NTP, or Network Time Protocol, is a widely used networking protocol that enables computers and devices to synchronize their system clocks with a reference time source. It ensures accurate timekeeping in computer networks by allowing devices to obtain precise time information from NTP servers, which are typically synchronized to highly accurate atomic clocks. NTP is essential for various applications and services that rely on synchronized time, such as network security, authentication, and data logging. vulnerability or the various types of network attacks.
Generally speaking, the correct answers are specific to each networking infrastructure and each customer’s policies. However, there are some general guidelines to follow to harden security on your SecureSync®, and this document should help. It covers the following areas and explains how to use each to prevent cyberattacks:
- Authentication and authorization
- HTTPS and SSL
- SFTP with public/private support
This document also consolidate the recommendations from various product manuals into one handy location. They identify each security feature, shows default settings and offers recommendations about whether you should choose to enable it.
To make it easier, we’ve also provided links to the online manuals for each protocol — so configuration help is just a click away.
