Staying on top of security is a big job, and Twitter can help. Here, in no particular order, is a list of 25 Twitter feeds that you'd do well to follow if you are a security specialist. Each person on the list is an accomplished hacker or researcher whose contributions to information security are helping make the Internet and software safer.

Bruce Schneier

Schneier is one of the foremost authorities on encryption in the country and a highly regarded expert on a range of security- and privacy-related topics. He is one of the creators of the Blowfish cipher algorithm, a fellow at Harvard Law School's Berkman Center for Internet & Society, and the author of several books on computer security and privacy.

Chris Wysopal

@WeldPond

A former programmer at Lotus and later a security researcher at hacker collective L0pht, Wysopal was part of a team that warned Congress about gaping Internet vulnerabilities as far back as 1998. Wysopal helped found Veracode, an application security vendor of which he is currently the CTO. A self-professed application security and security-transparency buff, Wysopal's tweets are newsy and cover a wide range of security-related topics.

Jeremiah Grossman

David Litchfield

Oxblood Ruffin 3.0

@OxbloodRuffin

A Canadian hacker and member of the Cult of the Dead Cow white-hat hacker group, Oxblood Ruffin is a prolific tweeter, whose sardonic, sometimes risqué takes on politics, religion, technology, and security are entertaining and informative.

Dan Kaminsky

@dakami

Kaminsky is a security researcher and chief scientist at White Ops. He is best known for his work involving DNS cache poisoning. He is one of just seven people with the authority to restore the DNS root keys on the Internet in the event of an emergency. Kaminsky retweets as much as, or even more, than he tweets himself but is worth following all the same.

The Grugq

@thegrugq

The Grugq is an independent security researcher whose takes on security and counterintelligence are followed by over 38,000 followers on Twitter. The Grugq is worth following for his ability to find and share some of the most relevant, important, and interesting tweets on security and related topics.

Anton Chuvakin

@anton_chuvakin

Chuvakin is vice president of research with Gartner's security and risk management practices team. He is a specialist in the areas of log management, security standards, and security information and event management. But his tweets touch upon a wide range of other, mostly security-related topics as well.

Based in Zagreb, Croatia, Kosutic is a specialist in information security standards and business continuity management. He is considered an expert resource on standards like the ISO 27001 and ISO 22301/BS 25999.

Richard Bejtlich

@taosecurity

Bejtlich is the chief security strategist at FireEye but is better known as the author of TaoSecurity, a blog that combines digital security with military history. The tweets of this former intelligence officer with the U.S. Air Force reflect his focus on thinking about security at a strategic level.

Jack Daniel

@jack_daniel

Daniel is a strategist at Tenable Network Security, but his real claim to fame is his work as a technology community activist.

Samy Kamkar

@samykamkar

Kamkar first gained fame, or notoriety, depending on your point of view, as a 19-year-old, when he exploited a security flaw in MySpace that allowed him to gain 1 million friends in a 20-hour period. Banned from using computers for three years after that caper, Kamkar these days is regarded as a brilliant security researcher whose recent exploits include breaking into keyless-entry vehicles and hacking drones.
