Artificial intelligence technologies have the potential to upend the longstanding advantage that attack has over defense on the Internet. This has to do with the relative strengths and weaknesses of people and computers, how those all interplay in Internet security, and where AI technologies might change things.
You can divide Internet security tasks into two sets: what humans do well and what computers do well. Traditionally, computers excel at speed, scale, and scope.
This essay appeared as half of a point/counterpoint with Priscilla Regan, in a CQ Researcher report on Privacy and the Internet.
Everything online is hackable. This is true for Equifax's data and the federal Office of Personal Management's data, which was hacked in 2015. If information is on a computer connected to the internet, it is vulnerable.
But just because everything is hackable doesn't mean everything will be hacked.
What the battle looks like after Section 702's reauthorization
For over a decade, civil libertarians have been fighting government mass surveillance of innocent Americans over the Internet. We've just lost an important battle. On Jan. 18, when President Trump signed the renewal of Section 702, domestic mass surveillance became effectively a permanent part of U.S. law.
Unprecedented computer-chip vulnerabilities exposed this month paint a grim picture of the future of cybersecurity.
On January 3, the world learned about a series of major security vulnerabilities in modern microprocessors. Called Spectre and Meltdown, these vulnerabilities were discovered by several different researchers last summer, disclosed to the microprocessors' manufacturers, and patched—at least to the extent possible.
This news isn't really any different from the usual endless stream of security vulnerabilities and patches, but it's also a harbinger of the sorts of security problems we're going to be seeing in the coming years. These are vulnerabilities in computer hardware, not software.
The security of pretty much every computer on the planet has just gotten a lot worse, and the only real solution—which,of course, is not a solution—is to throw them all away and buy new ones that may be available in a few years.
On Wednesday, researchers announced a series of major security vulnerabilities in the microprocessors at the heart of the world's computers for the past 15 to 20 years. They've been named Spectre and Meltdown, and they operate by manipulating different ways processors optimize performance by rearranging the order of instructions or performing different instructions in parallel. An attacker who controls one process on a system can use the vulnerabilities to steal secrets from elsewhere on the computer.
The cellphones we carry with us constantly are the most perfect surveillance device ever invented, and our laws haven't caught up to that reality. That might change soon.
This week, the Supreme Court will hear a case with profound implications for your security and privacy in the coming years. The Fourth Amendment's prohibition of unlawful search and seizure is a vital right that protects us all from police overreach, and the way the courts interpret it is increasingly nonsensical in our computerized and networked world.
Testimony and Statement for the Record of Bruce Schneier
Fellow and Lecturer, Belfer Center for Science and International Affairs, Harvard Kennedy School
Fellow, Berkman Center for Internet and Society at Harvard Law School
Hearing on "Securing Consumers' Credit Data in the Age of Digital Commerce"
Subcommittee on Digital Commerce and Consumer Protection

Mister Chairman and Members of the Committee, thank you for the opportunity to testify today concerning the security of credit data. My name is Bruce Schneier, and I am a security technologist. For over 30 years I have studied the technologies of security and privacy. I have authored 13 books on these subjects, including Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World (Norton, 2015).
Last Thursday, Equifax reported a data breach that affects 143 million US customers, about 44% of the population. It's an extremely serious breach; hackers got access to full names, Social Security numbers, birth dates, addresses, driver's license numbers -- exactly the sort of information criminals can use to impersonate victims to banks, credit card companies, insurance companies, and other businesses vulnerable to fraud.
Many sites posted guides to protecting yourself now that it's happened. But if you want to prevent this kind of thing from happening again, your only solution is government regulation (as unlikely as that may be at the moment).
In August, four US Senators introduced a bill designed to improve Internet of Things (IoT) security. The IoT Cybersecurity Improvement Act of 2017 is a modest piece of legislation. It doesn’t regulate the IoT market. It doesn’t single out any industries for particular attention, or force any companies to do anything.
The new book from Zeynep Tufekci looks at how the web has helped demonstrations take off around the globe, but also made them harder to sustain.
There are two opposing models of how the internet has changed protest movements. The first is that the internet has made protesters mightier than ever. This comes from the successful revolutions in Tunisia (2010-11), Egypt (2011), and Ukraine (2013). The second is that it has made them more ineffectual.
