New TLS interception warnings added in Chrome 63

Beginning from Chrome 63 release, the browser will notify users about the TLS interception occurrence, which frequently takes place during MitM (Man-in-the-middle) attacks. The release of the Chrome 63 version is scheduled for December 5, 2017.

As we mentioned earlier, Google, Mozilla, Microsoft and other major browser developers are actively promoting HTTPS. Websites that decided to switch over to the HTTPS receive some advantages such as better ranking in search results, as well as a higher level of trust from visitors.

When TLS can be intercepted?

One of the common reasons for intercepting TLS is man-in-the-middle attack. In this case, the attacker acts as intermediary in the interaction between the server and the user. All transmitted data goes through the attacker, and during that stage, he can intercept, examine and easily manipulate received information in any desirable way.

Quite frequently, the user is not even aware that he was a victim of MitM-attack and all of his data is now passing through the "filter" of the attacker. Google's decision to add notifications of TLS interception will allow site administrators to act in a timely manner in order to fix existing security problems and proactively respond to potential security threats.

TLS can also be intercepted using MitM approach for a good reason. In this case, traffic interception performed for analyzing it for the presence of malicious requests and viruses. This practice is ambiguous and may not be appreciated; therefore, it is best to avoid it. In this case, Chrome will not display any warnings.

How to enable TLS interception warnings in Canary, dev versions of Chrome

You can enable TLS interception warnings right now, if you use the dev version of Chrome named Canary. This is done as follows:

  1. In the browser, select Properties.
  2. In the Target field, enter the following: "-enable-features = MITMSoftwareInterstitial".
  3. Save the changes.

Symantec clients (including GeoTrust, Thawte and RapidSSL) must provide CAA in the DNS domain record

Just recently, the CA /B Forum has announced their decision, which states that all certifying authorities must comply with the Certification Authority Authorization (CAA) requirement for certificate issuance process. CAA allows domain owner to point out certain certification authority or authorities, which authorized to issue SSL / TLS certificates for this particular domain. It is significantly reduce the risk of unauthorized issuance of SSL / TLS certificates for a certain domain.

Certification authorities were prohibited from delegating domain / IP domain ownership verification by CA / B Forum decision

Until recently, certifying authorities were able to delegate the domain/IP verification process to third-party companies. Gervase Markham (Mozilla), as well as Ryan Sleevi (Google) and Mike Reilly (Microsoft) decided to make a proposal to the CA / B Forum about forbidding such practice.

Domain / IP verification is an important part of the identity verification activities performed by certification authority. Delegating these checks significantly complicates the audit of issued SSL certificates. Third-party companies may have no proper paperwork showing how they conducted domain / IP verification and whether this process was scrupulous and transparent.

The proposed changes require making adjustments in the Baseline Requirements, explicitly defining the term "authorized third party", and removing references to the possibility of delegating domain / IP checks for certifying authorities.

The proposal was adopted by a majority vote.

If you are looking to purchase certificates from trusted certification authorities that meet the requirements of the SSL industry, you can always do so in our LeaderSSL store.
