The dangers of Wildcard certificates

TLS/SSL certificates are used to authenticate servers (mostly Web) and encrypt traffic between websites and users. Thus, they ensure the integrity of the data exchanged and prevent data spying. The digitalization of the company and the world in general, as well as the browsers’ desire to impose HTTPS:// by default, have multiplied exponentially the need for certificates. To meet these growing needs, the wildcard certificate (*.domainname.com) is increasingly being considered by companies. ... Read More

HTTPS://: China doesn’t like confidentiality and blocks the ESNI extension

According to a joint report by iYouPort, the University of Maryland, and the Great Firewall Report, TLS connections using the preliminary encrypted SNI extension (ESNI) are being blocked in China. A new step towards censorship and a desire to be able to track Internet users. What is SNI (Server Name Indication)? When an Internet user consults a website in HTTPS://, it means that the site is secured by an SSL/TLS certificate. The consultation of the website begins with the establishment of the se...

The importance of reverse DNS

Reverse DNS is often unknown to domain name managers, especially when the names are hosted by major hosting companies. Reverse DNS allows you to resolve from an IP address to an FQDN. This is the exact opposite of the classic use of DNS, which associates domain names to IP addresses. The reverse DNS allows to answer the question: I have an IP address, what is the FQDN related to it? Reverse DNS operates by creating a reverse DNS zone in which DNS PTR records (for Pointer Record) will be configur... Read More

Choosing the right TLD based on DNS performance

Comparative analysis of the famous Top Level Domains (.com, .fr…) The crux of the war for high-visibility websites is the download time. As a natural referencing factor admitted by Google, this download time can be significantly impacted during DNS resolution. If it is necessary to rely on a first-class DNS infrastructure, the choice of the extension associated with a domain name is important. Indeed, not all registries perform equally well in terms of DNS, not to say that some have disapp... Read More

Let’s Encrypt, do not confuse confidentiality and security

Let’s Encrypt was recently the subject of discussions in the small world of TLS certificates, by suddenly revoking 3 048 289 certificates which should not have been issued. A bug in its validation software prevented CAA registrations controls, and the certificates in question should not have been initially issued. These significant disruptions resulted from this mass revocation, but it is difficult to complain about a free service. I am often asked what I think of Let’s Encrypt, and I ... Read More

2020 and the SSL, a small prediction exercise

Browsers and Certification Authorities, the battle continues. 2019 was a busy year, with growing differences of opinion between browsers makers and Certification Authorities, an explosion in the number of phishing sites encrypted in HTTPS and significant progress on the depreciation of TLS v1.0. Discussions on extended validation, more generally the visual display of certificates in browsers, and the reduction of the duration of certificates have taken a prominent place. None of these discussion... Read More

The financial industry, the target of more and more costly attacks on the DNS

Financial services companies are particularly affected by cyberattacks. They possess a wealth of information on the customers, protect their money and provide essential services which must be available day and night. They are a lucrative target. Among the favored lines of attacks: the DNS. The Efficient IP’s Global DNS threat annual report shows a constant growth of the DNS attacks’ number and the financial impacts, with an average financial loss of 1.2 million euros in 2019. This amount was est... Read More

Soon a maximum duration of one year for SSL certificates?

What is happening? The industry actors plan to reduce the lifetime of SSL/TLS certificates, allowing the HTTPS display in browsers, to 13 months, i.e. almost half of the present lifetime of 27 months, in order to improve security. Google through the CA/Browser Forum has indeed proposed this modification, approved by Apple and a Certification Authority, making it eligible to vote. During the next CA/B Forum meetings, if the vote is accepted, the modification of the requirements will come into eff... Read More
