The Extended Validation (EV) condition of all certificates issued past times Symantec-owned certificate regime volition no longer last recognized past times the Chrome browser for at to the lowest degree a twelvemonth until Symantec fixes its certificate issuance processes thence that it tin dismiss last trusted again.
Extended validation certificates are supposed to render the highest bird of trust too authentication, where earlier issuing a certificate, Certificate Authority must verify the requesting entity's legal beingness too identity.
The movement came into upshot straight off afterward Ryan Sleevi, a software engineer on the Google Chrome team, made this proclamation on Th inwards an online forum.
"This is too coupled alongside a serial of failures next the previous laid of misissued certificates from Symantec, causing us to no longer cause got confidence inwards the certificate issuance policies too practices of Symantec over the past times several years," says Sleevi.
One of the of import parts of the SSL ecosystem is Trust, simply if CAs volition non properly verifying the legal beingness too identity earlier issuing EV certificates for domains, the credibility of those certificates would last compromised.
Google Chrome Team started its investigation on Jan xix too constitute that the certificate issuance policies too practices of Symantec from past times several years are dishonest that could threaten the integrity of the TLS organization used to authenticate too secure information too connections over the Internet.
Under this move, the Google Chrome squad has proposed next steps every bit punishment:
1. EV certificates issued past times Symantec till today volition last downgraded to less-secure domain-validated certs, which way Chrome browser volition straight off halt displaying the refer of the validated domain refer holder inwards the address bar for a menses of at to the lowest degree a year.
2. To boundary the gamble of whatever farther misissuance, all newly-issued certificates must cause got validity periods of no greater than nine months (effective from Chrome 61 release) to last trusted inwards Google Chrome.
3. Google proposes an incremental distrust, past times gradually reducing the "maximum age" of Symantec certificates over the course of pedagogy of several Chrome releases, requiring them to last reissued too revalidated.
Chrome 59 (Dev, Beta, Stable): 33 months validity (1023 days)This means, starting alongside Chrome 64, which is expected to come upward out inwards early on 2018, the Chrome browser volition solely trust Symantec certificates issued for nine months (279 days) or less.
Chrome lx (Dev, Beta, Stable): 27 months validity (837 days)
Chrome 61 (Dev, Beta, Stable): 21 months validity (651 days)
Chrome 62 (Dev, Beta, Stable): fifteen months validity (465 days)
Chrome 63 (Dev, Beta): nine months validity (279 days)
Chrome 63 (Stable): fifteen months validity (465 days)
Chrome 64 (Dev, Beta, Stable): nine months validity (279 days)
Google believes this movement volition ensure that spider web developers are aware of the gamble of hereafter distrust of Symantec-issued certs, should additional misissuance events occur, spell too giving them "the flexibility to overstep away along using such certificates should it last necessary."
Symantec Response – Google's Claims Are "Exaggerated too Misleading"
Symantec has responded and stated that the claim of mis-issuing 30,000 SSL certificates made past times Google are "Exaggerated too Misleading".
"We strongly object to the activity Google has taken to target Symantec SSL/TLS certificates inwards the Chrome browser. This activity was unexpected, too nosotros believe the weblog ship service was irresponsible."
"While all major CAs cause got experienced SSL/TLS certificate mis-issuance events, Google has singled out the Symantec Certificate Authority inwards its proposal fifty-fifty though the mis-issuance lawsuit identified inwards Google’s weblog ship service involved several CAs."
