FinnIn der Medizin scheint IT Sicherheit besonders schwierig zu sein.
Heutiges Beispiel: selbst signierte Zertifikate bei der Radiologie in Blankenese
Da steckt zwar "nur" eine Weiterleitung hinter, aber trotzdem echt unschön.
Junicast#Selfsigned certificates are more trustworthy thus more secure.
betamax65Die Aufregung um #selfsigned Zertifikate in der #ITSecurityIndustrie ist jedes Mal wieder amüsant. Ich persönlich vertraue meiner eigenen #rootCA blind – mehr als jedem undurchsichtigen, kommerziellen #SSL-Anbieter.
Computers & Networks#Windows #ProtectedEventLogging is not just for businesses to use. It should also be used on personal devices. It does need to generate a #TrustedCertificate that goes in the #CertificateStore. This might need a #windows edition higher than #Home which cost more to get a #Pro edition at the very least. @computers8networks tr.ee/wim7nV
Update: You can #create #SelfSigned #certificates on #WindowsHome edition using #PowerShell with #Admin #Privileges.

I do have doubts about whoever made that certificate though. Must be predating Unicode.
I probably can demand a raise now. A few extra groats of buckwheat per week.

@lucasmz yes and no..
Yes in that one can just revoke said keys and deploy one's own!
No if you can't revoke the preset #CensorBoot keys in your #UEFI.
No in that these keys are default and that any revocation is 100% reversibe AFAICT.
No in that this would brick #Windows10, #Windows11 and even some #Linux install media.
Personally I'd wish for #heads and #PGP #SelfSigned code to be the norm providing the user/owner with full control over what is executeable!
robrichhttps://auth0.com/blog/test-authorization-in-aspnet-core-webapi-with-user-jwts-tool/ - `dotnet user-jwts create --claim permissions=create:term` create #SelfSigned #JWT for an #ASPnet site. Then `dotnet user-jwts list` to show created JWTs. Great for testing. Nice article https://www.linkedin.com/in/andreachiarelli/.
@So, #OpenKeychain is unmaintained, and the code a mess, according to former devs. Otoh #CipherMail is actively developed. I'm not saying effective #OpenPGP on #Android is dead, but it's not in an ideal state, when cool projects like @keyoxide make #PGP more exciting. However, maybe time for #selfsigned #SMIME?

how to use a self signed certificate to intercept traffic in MITM attack
We have a project at university about MITM attacks and our focus is to show how one can get into the communication between two endpoints, given different circumstances and security measures (that we

Try this
nmap --script=ssl-cert.nse 10.10.10.0/24 | grep -i Issuer | grep -i 'IOS-Self-Signed-Certificate'
If the above returns any results (adjust subnets accordingly) then you might want to read this:

Field Notice: FN - 70489 - PKI Self-Signed Certificate Expiration in Cisco IOS and Cisco IOS XE Software - Software Upgrade Recommended
Self-signed X.509 PKI certificates (SSC) that were generated on devices that run affected Cisco IOS or Cisco IOS XE software releases expire on 2020-01-01 00:00:00 UTC. New self-signed certificates cannot be created on affected devices after 2020-01-01 00:00:00 UTC. Any service that relies on these self-signed certificates to establish or terminate a secure connection might not work after the certificate expires.
