The padlock on a browser’s address bar is supposed to give Net travelers some security in insecure virtual space, but that’s not always the case. Some dangerous flaws lurk behind the padlock.
They can weaken the effectiveness of encrypted Internet connections and compromise TLS/SSL processes, including domain validation, end-to-end encryption, and the chains of trust certificate authorities have put in place, Google points out at its SSL certificate transparency website.
The flaws leave the doors open for a wide range of security attacks, including website spoofing, server impersonation and man-in-the-middle attacks, the company said.
In the past, there hasn’t been a way to determine what SSL certificates a certificate authority has issued. That creates a problem because all certificates are trusted by a Web browser no matter who issues it — even though some CAs may have better security and fraud controls than others.
“There are over 300 certificate-issuing authorities, and they’re not all created equal,” said Kevin Bocek, vice president for security strategy and threat intelligence atVenafi.
Early Warning System
Google became concerned over the SSL certificate issuance problem because it saw certificates issued in its name that were being used by criminals and nation-states for fraud and mischief.
It’s spearheading a movement to improve transparency when issuing certificates. When a CA issues an SSL certificate, Google wants notice of that issuance to be posted to a public place.
That public place has become a number of log servers where certificates can be posted before they’re approved. It allows anyone interested in what certificates are being issued to see them before they go live.
“If I’m monitoring one of these log servers, and I see a certificate that’s for my domain, and I know I didn’t request that certificate and don’t do business with that certificate authority, alarms bells should go off,” Bocek told TechNewsWorld.
Weeding CA Ecosystem
Transparency isn’t a panacea for all the ills in the cert system.
“Certificate transparency doesn’t solve all of the trust issues at all, but it does provide a good way to allow certificate misissuance to be detected after the event,” said Robin Alden, chief technical officer forComodo.
If bad SSL certificates can be detected, it will be easier to identify CAs deliberately abusing their authority or accidentally issuing defective certificates, he told TechNewsWorld.
Either way, “their mistakes are likely to be found sooner rather than later, and that helps to reduce the impact of such mistakes,” Alden said.
“Together with widely accepted standards for CAs and an external audit regime, certificate transparency can help both to strengthen the trust in CAs and to weed out any inadequate or malicious CA,” he added.
While transparency can address problems CAs acting in good faith may face with issuing SSL certificates, if a CA is hacked, all bets are off.
That’s because if a bad actor is able to gain control of a CA’s machinery to issue certificates, those certificates won’t appear on any Certificate Transparency server. The same is true for unscrupulous CAs that issue certs without prepublishiing them on a CTS.
“Transparency helps reduce the risk,” Venafi’s Bocek said. “It doesn’t eliminate it.”
However, Google has made it difficult in some cases for even those hackers and fly-by-night CAs to get their certificates trusted.
“Google requires that if you issue a certificate with the highest level of trust — the extended validation certificate — you must prepublish that certificate on a Certificate Transparency log server,” Bocek explained.
Websites with EV certificates are displayed differently on a browser’s address bar than other websites. The green area beside the padlock icon is longer and usually displays more information about the certificate owner.
“Extended validation requires a great deal effort on the [part of the] person applying for that certificate because they have to prove they are that business,” John Graham-Cumming, a programmer withCloudFlare, told TechNewsWorld.
There is some urgency in solving the problems associated with certificates now, especially before the mandate that all federal government websites have a digital certificate is fully implemented.
“That raises the stakes for certificate authorities. They’re going to become more of a target,” Bocek said.
“We know there are underground marketplaces that are selling digital certificates,” he added. “It’s a commodity that can be quickly monitored.”
Judicial Redress Act
European authorities last week continued their campaign to ensure that the personal information of their citizens stored by American companies meets European Union privacy standards.
Ireland’s High Court ordered an investigation of Facebook to ensure that data gathered from EU users is properly protected from surveillance by U.S. government agencies.
In Austria, an appeals court overturned a lower court ruling that prevented law student Max Schrems from filing a lawsuit against Facebook for a number of alleged rights violations, including its tracking of user data and its involvement with an NSA surveillance program.
Earlier this month, Schrems’ lawsuit resulted in the European Court of Justice invalidating the “Safe Harbor” agreement between the EU and United States. That pact allowed U.S. companies to handle Europeans’ personal data without meeting stringent European privacy rules.
Strengthening Uncle Sam’s Hand
Meanwhile, the U.S. House of Representatives moved to address one of the privacy concerns European authorities raised by passing and sending to the Senate the Judicial Redress Act.
The measure would allow some foreign citizens to challenge in U.S. courts violations of the federal Privacy Act by the U.S. government related to the sharing of law enforcement information between Uncle Sam and some foreign governments.
“This is one of the few instances of the U.S. Congress enhancing the privacy protections of non-Americans,” said Jens-Henrik Jeppesen, the director of European affairs for theCenter for Democracy & Technology.
“While the Judicial Redress Act does not extend the full Privacy Act protections that U.S. citizens receive to EU citizens, it is certainly positive progress in improving how very personal data is shared between the EU and U.S.,” he added.
Passage of the JRA should strengthen the United States’ position when hammering out a new Safe Harbor agreement with the Europeans, noted Berin Szoka, president ofTechFreedom.
“Passage of the Judicial Redress Act is table stakes for the U.S.,” Szoka said. “Without it, the State Department will have no credibility at the bargaining table in negotiating with the Europeans over a replacement for Safe Harbor.”
