I like to share the experience we suffered from distrust, it is disastrous for CA and its customers to replace the certificate that exceed your imagination that we are still working for this since October 2016 that nearly six months now.
Due to the quantity of Symantec customers is more than WoSign and most companies are bigger than WoSign's customers, I am sure that the interoperability and compatibility failures could bring big problem to Symantec, to Symantec customers and the Browser users. I think Symantec's proposal is good and will benefit its customers that it will not make the world mess. Thanks.

These customers include many of the largest financial services, critical infrastructure, retail and healthcare organizations in the world, as well as many government agencies. This cohort is an important constituency that we believe has been under-represented to date in the public commentary that has been posted to the Google and Mozilla boards since large organizations rarely authorize employees to engage in such public discussions, particularly in an area related to security. We first solicited feedback to understand the disruption that a browser-initiated trust change, like the one proposed by Google, would cause organizations that opt to replace their existing SSL/TLS certificates in order to maintain interoperability with all browsers. We learned that these organizations’ publicly facing web applications, while extensive, only represent a fraction of their dependency on publicly trusted Symantec roots. Many large organizations have complex, and potentially undocumented and little-known dependencies on their certificate infrastructure. Examples of complex dependencies on Symantec public roots that our customers have shared or we have identified include: - Embedded devices that are pinned to certificates issued by a Symantec public root to communicate to resources over the Internet or Intranet. Replacing these certificates would result in immediate failures and the need to recode and reimage the firmware for these devices. - Mobile applications that have pinned certificates. Replacing server certificates would require these applications to be recoded, recompiled and redistributed. - Critical infrastructure organizations that use certificates issued off of Symantec roots to validate internal and external resources. In many cases the applications being used are pinned to Symantec certificates. - Some large organizations use certificates chained to Symantec public roots for nearly all internal applications and communications. Many of these organizations are under regulatory requirements to encrypt even internal communications. Additionally, many of these organizations estimate that just the planning process to prepare to move to a new certificate authority could take many months and in some cases years because of unknown and undocumented dependencies. Moreover, few large enterprises that we’ve received feedback from have implemented the level of certificate lifecycle automation required to enable safe and cost-effective adoption of shorter validity certificates. We believe that it is important for the broader community to understand and give more weight to these compatibility and interoperability risks, particularly given the fact that many of these organizations are prohibited from commenting publicly on these topics. To give a perspective of scale, Symantec secures more than 80% of the world’s ecommerce transactions through its certificate infrastructure. Additionally, Symantec is the world’s largest provider of Organization Validation (OV) and Extended Validation (EV) certificates which are primarily used by large enterprises. Many of these certificates sit inside corporate and government networks and are an important part of the trust fabric of internal communications. In short, our assessment based on customer feedback is that the interoperability and compatibility failures that could result from a large-scale certificate replacement or invalidation event would be significant and unpredictable. _______________________________________________ dev-security-policy mailing list firstname.lastname@example.org https://lists.mozilla.org/listinfo/dev-security-policy
