Hej!
Tänkte höra mig för vilka MFA-metoder som används eller funderar på att användas som uppfyller de krav som AL2 och AL3 ställer?
Dvs, tekniker som uppfyller kraven och möjligen fungerar efter 2025/2027?
Vad är det för produkter som används?
Hur "brett" använder ni dessa?
Är det någon som använder samma MFA-lösning i andra system utöver er IDP?
Tror frågorna räcker.
Anledningen är att vi tittar på att uppdatera AL2 (eller AL3) där vi försöker få tips på vilka tekniker som finns och som går/kommer gå att använda inom Swamid idag och i framtiden.

Hej,
För kännedom till er som kör.
Tänk dock på att mjukvara TOTP inte är tillåtet i SWAMID efter 2025.

Hej
Jag stötte på ett litet problem när jag försökte uppgradera OSet på vår IDP-server (Ubuntu). Det är två paket som inte kan autouppdateras och verkar behöva skötas manuellt - mysql-server och mysql-client. Två frågor, vad exakt används dessa till på IDP-servern (den server kör endast IDP) och vad är smidigaste sättet att uppdatera dessa på (om det nu behövs)?

Hej,
För kännedom.
Är samma säkerhetshål som för Shibboleth SP som vi skickar om förra veckan. Men nu är det IdP:n som har fått en fix.
Inte lika akut som SP:n men ni bör nog uppgradera ändå.
Infon skickad till saml-admins + admin, teknik och säkerhetskontakt i metadatat för de Shibboleth IdP jag hittat i SWAMID

> =================================================================

> The IdP's support for inbound SAML assertions (proxying SAML

Hallihallå!
Onsdag 26 mars med start klockan 09.00 kommer vi göra underhåll på metadata.swamid.se. Borde gå snabbt och smärtfritt, meddelar via denna kanal när allting är klart och verktyget redo att användas igen.

Hej
Det kom in ett mail gällande sårbarheten i OpenSAML tidigare (https://wiki.sunet.se/pages/viewpage.action?pageId=241119211) dock står det väldigt lite kring hur man går tillväga med en uppdatering. Finns det någon lite mer detaljerad beskrivning eller tutorial för detta? Alt om någon har gjort det redan och kan hjälpa med instruktioner för Ubuntu.
Är det fler delar som påverkas och behöver uppdateras när man uppdaterar OpenSAML?

Hej.
Som info.
För er på Windowsplatformen kvittar 3.5.0.1 eller 3.5.0.2 båda är säkra men 3.5.0.2 visar rätt version i loggen.
Linux
CentoOS/Redhat mfl finns ju RPM:er från Shibboleth.net <http://shobboleth.net/>
Debian - Släppte en fixad version för Shibboleth 3.4 i Söndags.
Ubuntu - Finns buggraporter men inget släppt officielt. SUNET kör en del Ubuntu dock inte senaste. En kollega har byggt för oss :-) https://launchpad.net/~sunet/+archive/ubuntu/ppa

> It was noted there's a second log line in the shibd.log output that reports the older OpenSAML version (3.3.0) instead of the correct one. This is cosmetic, and the correct version was logged later on in the file, but this is now corrected in the new patch to aid in assessing the state of systems in light of the recent advisory.

Hej!
Vi får rapporter om att användare får MFA-krav när dom ska attestera
betyg i både test och prod-miljön.
Någon annan som ser det eller är det bara vår "instans" som är drabbad?

Hej.
Det har i dag släppts information om 2 säkerhetshål i SAML.
HTTP-POST-SimpleSign i Shibboleth och HTTP-Redirect i SimpleSAMLphp.
Kort så bör ni som kör Shibboleth antingen plocka ner och kompilera upp senaste OpenSAML (3.3.1) och Shibboleth 3.5 eller uppdatera en fil på burken.
Många Linuxdistibutioner kör kvar på Shibboleth 3.4 och OpenSAML 3.2.x!
Då HTTP-POST-SimpleSign normalt inte används går det att plocka bort supporten i SP:n.
Gå in i protocols.xml och radera raden
<Binding id="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST-SimpleSign"
path="/SAML2/POST-SimpleSign" />
För er som kör SimpleSAMLphp gäller att uppdatera till senaste versionen 2.3.7 eller 2.2.5
