Politics aside, if there was ever a time for an Apollo-like moonshot program to build secure infrastructure and write secure code, it&#x27;s now. Thanks to wide dissemination of techniques, Attack As A Service and even AI-assisted hacking, the bar to mount attacks just keeps getting lower. The real answer is to build resilient systems with <i>zero</i> backdoors rather than trying to put the hacking genie back in its proverbial bottle.

&gt;The reliance of Ukraine’s substations on GPS for time synchronization, a standard in industrial control systems for its accuracy and affordability, becomes a vulnerability when faced with such jamming.<p>&gt;Cisco’s response involved shipping a large order of modified equipment, specifically designed to maintain accurate time even under radio jamming conditions. This solution employs the Cisco Industrial Ethernet switch with an internal crystal oscillator, enabling new clock recovery algorithms for accurate timekeeping when GPS is unavailable.<p>That&#x27;s really neat. Didn&#x27;t know GPS was also used for time synchronization.

So they put a rubidium oscillator in the Cisco boxes or upgraded their current equipment line.<p>slide 15 has other solutions to gps denial. <a href="https:&#x2F;&#x2F;www.gps.gov&#x2F;cgsic&#x2F;meetings&#x2F;2016&#x2F;silverstein.pdf" rel="nofollow noreferrer">https:&#x2F;&#x2F;www.gps.gov&#x2F;cgsic&#x2F;meetings&#x2F;2016&#x2F;silverstein.pdf</a><p>IEEE 1588-2008 is a good solution at 10 updates per second.

Let&#x27;s hear about offence Cisco puts out against US enemy states, or even against subordinate states just in case.
