Rules (2024-08-30)

  1. This is an English-language community. Comments should be in English. Posts can link to non-English news sources when providing a full-text translation in the post description. Automated translations are fine, as long as they don't overly distort the content.
  2. No links to misinformation or commercial advertising. When you post outdated/historic articles, add the year of publication to the post title. Infographics must include a source and a year of creation; if possible, also provide a link to the source.
  3. Be kind to each other, and argue in good faith. Don't post direct insults nor disrespectful and condescending comments. Don't troll nor incite hatred. Don't look for novel argumentation strategies at Wikipedia's List of fallacies.
  4. No bigotry, sexism, racism, antisemitism, islamophobia, dehumanization of minorities, or glorification of National Socialism. We follow German law; don't question the statehood of Israel.
  5. Be the signal, not the noise: Strive to post insightful comments. Add "/s" when you're being sarcastic (and don't use it to break rule no. 3).
  6. If you link to paywalled information, please provide also a link to a freely available archived version. Alternatively, try to find a different source.
  7. Light-hearted content, memes, and posts about your European everyday belong in !yurop@lemm.ee. (They're cool, you should subscribe there too!)
  8. Don't evade bans. If we notice ban evasion, that will result in a permanent ban for all the accounts we can associate with you.
  9. No posts linking to speculative reporting about ongoing events with unclear backgrounds. Please wait at least 12 hours. (E.g., do not post breathless reporting on an ongoing terror attack.)
  10. Always provide context with posts: Don't post uncontextualized images or videos, and don't start discussions without giving some context first.

(This list may get expanded as necessary.)

Posts that link to the following sources will be removed

Unless they're the only sources, please also avoid The Sun, Daily Mail, any "thinktank" type organization, and non-Lemmy social media. Don't link to Twitter directly, instead use xcancel.com. For Reddit, use old:reddit:com

(Lists may get expanded as necessary.)

Ban lengths, etc.

We will use some leeway to decide whether to remove a comment.

If need be, there are also bans: 3 days for lighter offenses, 7 or 14 days for bigger offenses, and permanent bans for people who don't show any willingness to participate productively. If we think the ban reason is obvious, we may not specifically write to you.

If you want to protest a removal or ban, feel free to write privately to the primary mod account @EuroMod@feddit.org

Europe leads the world in exposed solar power equipment, raising alarms on infrastructure security, report finds (www.forescout.com)

Archived

Security firm Forescout identified almost 35,000 solar power devices from 42 vendors with exposed management interfaces. These devices include inverters, data loggers, monitors, gateways and other communication equipment.

Key Findings

  • Despite being a rapidly growing renewable energy source, there are security issues with remote inverter management, via cloud applications or direct access to management interfaces within inverters.
  • Internet-exposed solar power devices are much more popular in Europe and Asia than in other regions. Europe accounts for 76% of exposed devices, followed by 17% in Asia and the remaining 8% in the rest of the world. Germany and Greece each account for 20% of the total devices worldwide, followed by Japan and Portugal with 9% each then Italy with 6%.
  • Four of the top 10 vendors with exposed devices are headquartered in Germany, two in China and one each in Austria, Japan, US and Italy. This distribution also does not match the top 10 vendors worldwide by market share, since 9 of those are Chinese.

Mitigation Recommendations

  • Do not expose inverter management interfaces to the internet.
  • Patch devices as soon as possible and consider retiring those that for some reason cannot be patched.
  • If a device needs to be managed remotely, consider placing it behind a VPN and following CISA’s guidelines for remote access.
  • Follow the NIST guidelines for the cybersecurity of smart inverters in residential and commercial installations.

~~Patch devices as soon as possible and consider retiring those that for some reason cannot be patched.~~

Require all device firmware to be open source, and require all other software to be open sourced the moment it stops receiving sufficient support.

Yes, and produce more of this stuff in Europe. And do not expose inverter management interfaces to the internet.

...and require electricians to not think of themselves as IT experts that should have any say in configuring anything beyond maybe actual modbus on two wires.

Thank god we do not buy or oil and gas from some dicatorship.....

There is no Europe. Just Asia. If a chain of moutain could separate continent then Germany and Italy aren't on the same one

You mean the continent Eurasia?
