Voluntary Reporting of Cybersecurity Incidents

One of the problems with trying to secure systems is the lack of knowledge in the community about what has or hasn't worked. I'm on record as calling for an analog to the National Transportation Safety Board: a government agency that investigates major outages and publishes the results. In the current, deregulatory political climate, though, that isn't going to happen. But how about a voluntary system? more

Enabling Privacy Is Not Harmful

The argument for end-to-end encryption is apparently heating up with the work moving forward on TLSv1.3 currently in progress in the IETF. The naysayers, however, are also out in force, arguing that end-to-end encryption is a net negative... The idea of end-to-end encryption is recast as a form of extremism, a radical idea that should not be supported by the network engineering community. Is end-to-end encryption really extremist? Is it really a threat to the social order? more

RIPE 75: Imprssions of the Meeting

RIPE held its 75th meeting in Dubai in mid-October. As usual, there was a diverse set of presentations covering a broad range of activities that are taking place on today's Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centers, IPv6, the DNS, routing and network measurement. If that's not enough, the topic of the Internet of Things has been added as a Working Group in the RIPE pantheon. If you add address policy, database and RIPE services to the mix, you get a pretty packed five days with topics that would appeal to most Internet folks. more

Equifax Breach: 9 Fraud Prevention Steps Everyone Should Take

The U.S. Internet Revenue Service now says that criminals already had most of the information that credit bureau Equifax lost in a breach that revealed personal information about nearly 150 million people. The incident at Equifax and the IRS' mid-October admission of how much-stolen data was already in criminal hands may force changes in how the world handles personal information. more

Two More Crypto Holes

If you work in computer security, your Twitter feed and/or Inbox has just exploded with stories about not just one but two new holes in cryptographic protcols. One affects WiFi; the other affects RSA key pair generation by certain chips. How serious are these? I'm not going to go through the technical details. For KRACK, Matthew Green did an excellent blog post; for the other, full details are not yet available. There are also good articles on each of them. What's more interesting are the implications. more

A Closer Look at Postponing of the Root Zone KSK Rollover Decision

On Sept. 27, Internet Corporation for Assigned Names and Numbers (ICANN) announced that the first root zone Key Signing Key (KSK) rollover - originally scheduled to take place on Oct. 11 - will be postponed. Although this was certainly a difficult decision, we fully agree that erring on the side of caution is the best approach to take. In this blog post, I want to explain some of the involvement Verisign has had in KSK rollover preparations, as well as some of the recently available research opportunities which generated data that we shared with ICANN related to this decision. more

A European Perspective on the Equifax Hack: Encouraging Data Security Through Regulation

The Equifax hack is understood to have compromised the personal data of over 140 million individuals. Although recent hacks of other businesses have affected more individuals, the personal data held by Equifax is significantly more sensitive than the data compromised in other hacks and includes Social Security numbers, birth dates, current and previous addresses and driver licence details...

Preliminary Thoughts on the Equifax Hack

As you've undoubtedly heard, the Equifax credit reporting agency was hit by a major attack, exposing the personal data of 143 million Americans and many more people in other countries. There's been a lot of discussion of liability; as of a few days ago, at least 25 lawsuits had been filed, with the state of Massachusetts preparing its own suit. It's certainly too soon to draw any firm conclusions... but there are a number of interesting things we can glean from Equifax's latest statement. more

Security is a System Property

There's lots of security advice in the press: keep your systems patched, use a password manager, don't click on links in email, etc. But there's one thing these adages omit: an attacker who is targeting you, rather than whoever falls for the phishing email, won't be stopped by one defensive measure. Rather, they'll go after the weakest part of your defenses. You have to protect everything -- including things you hadn't realized were relevant. more

Not Quite Two Factor, or Is Your Phone Number Really Something You Have?

A recent article in the New York Times Dealbook column reported on phone number hijacking, in which a bad guy fraudulently takes over someone's mobile phone number and used it to reset credentials and drain the victim's account. It happens a lot, even to the chief technologist of the FTC. This reminds us that security is hard, and understanding two-factor authentication is harder than it seems. more
