Have you ever thought of automating the certificate issuing in your organization’s internal certification authority? How about using the same procedure as in Let’s Encrypt and the ACME protocol, while enjoying all the benefits ACME has to offer? The possible solution is to use Boulder. I will now try to break down for you the Boulder’s installation process and the pitfalls that I encountered during the setup.
One of the most comprehensive open source intrusion detection systems Suricata held its annual conference in Prague. And because CZ.NIC intensively uses Suricata in its Turris routers to protect users, we have become a proud partner of the event. There, we shared our experience with other Suricata users and showed the technological solution of the Turris Omnia router, where Suricata can be operated with ease.
A golden opportunity: the bank we’re about to rob is moving to new premises today. To our luck, they’re also testing alarms until 4 PM, so it won’t be suspicious if we accidentally set one off. There is an open window on the first floor protected by a single sensor. Our inside man among the staff has placed an IP camera into the sensor cabinet, so we can see if the sensor we are trying to break has the ‘status OK’ or the alarm is screaming. The IP camera is streaming to YouTube — alas with a delay. The problem is that the sensor communicates via radio waves: every 15 to 30 seconds the diode beeps and the device sends a signal. We’re listening, trying to imitate it, and when we’re sure, we’re gonna shut down the sensor and turn on our little imitation that we built. What is left is just to arrange the tin foil between the antennas, like this… the sensor alarm’s blaring! We are holding our ears and will try again in half a minute.
