Exploiting the Firewall Beachhead: A History of Backdoors Into Critical Infrastructure

There is no network security technology more ubiquitous than the firewall. With nearly three decades of deployment history and a growing myriad of corporate and industrial compliance policies mandating its use, no matter how irrelevant you may think a firewall is in preventing today's spectrum of cyber threats, any breached corporation found without the technology can expect to be hung, drawn, and quartered by both shareholders and industry experts alike. more

US Department of Homeland Security Issues Emergency Directive Ordering Agencies to Audit DNS Records

The U.S. Department of Homeland Security has issued a rare "emergency" directive ordering federal agencies to audit all DNS records within ten days. more

Average Daily Malware at All Time High, Spam Lowest Since 2008

McAfee, Inc. today unveiled its McAfee Threats Report: Third Quarter 2010, which uncovered that average daily malware growth has reached its highest levels, with an average of 60,000 new pieces of malware identified per day, almost quadrupling since 2007. At the same time, spam levels decreased in volume this quarter, both globally and in local geographies. Spam hit a two year low this quarter while malware continued to soar. More than 14 million unique pieces of malware were identified in 2010, one million more than Q3 2009. more

Tackling Cyber Security: Should We Trust the Libertarians?

One of the RSS feeds that I read is Reason magazine, which is a web site for libertarians. In general, libertarians want less government intervention both in our personal lives and in the economy. The idea behind libertarians is that today's Republicans want less government intervention in our economy but are perfectly fine to have them dictate some aspects of morality. Similarly, today's Democrats want less government intervention in our personal lives but are perfectly fine with creating government bureaucracy to deliver social services. That's an oversimplified summary, but is more or less correct. About two months ago I got an article in my RSS feed where Reason was commenting on the government's response to the cyber war threats. more

A Cynic’s View of 2015 Security Predictions - Part 4

Lastly, and certainly not the least, part four of my security predictions takes a deeper dive into mobile threats and what companies and consumer can do to protect themselves. If there is one particular threat category that has been repeatedly singled out for the next great wave of threats, it has to be the mobile platform -- in particular, smartphones... The general consensus of prediction was that we're (once again) on the cusp of a pandemic threat. more

Closing the Gaps: The Quest for a Secure Internet

Over the last year the world has been virtually buried under news items describing hacks, insecure websites, servers and scada systems, etc. Each and every time people seem to be amazed and exclaim "How is this possible?" Politicians ask questions, there is a short lived uproar and soon after the world continues its business as usual. Till the next incident. In this blog post I take a step back and try to look at the cyber security issue from this angle... more

A Year in Review: 14,000 Routing Incidents In 2017

How was the state of the Internet's routing system in 2017? Let's take a look back using data from BGPStream. Some highlights: 13,935 total incidents (either outages or attacks like route leaks and hijacks); Over 10% of all Autonomous Systems on the Internet were affected; 3,106 Autonomous Systems were a victim of at least one routing incident; 1,546 networks caused at least one incident. more

Hospitals Advised to Prepare for a Month of Downtime Following Cyberattacks

The Joint Commission, a healthcare accreditation agency, has advised hospitals and health systems to brace for at least a month of downtime following a cyberattack, according to The Wall Street Journal. This recommendation is part of new guidelines released by the agency for handling IT security events. more

The Reality Virus

There's a new virus infecting the Internet that's more pernicious and more dangerous than any virus that has gone before. It's the first example ever of a hybrid Internet-human virus and probably the universal common ancestor of all hybrid Internet-human viruses to come. The condition the virus leaves behind is increasingly well recognised and goes by the understated label of "post-truth" but the virus itself is so far anonymous and so I propose we name it after the effect it has on those it has infected who, put simply, can no longer distinguish reality from fiction, hence the reality virus. more

Google and China: What Business Are Telcos Really In?

It seems like there's a different headline story about Google every day lately, and there's a lot here that service providers should be paying attention to. The launch of Nexus One around CES earlier this month is especially important for all mobile operators as well as the handset vendors partnering with them. A few days later, we started hearing noise about Google Energy. more

Password Leaks

The technical press is full of reports about the leak of a hashed password file from LinkedIn. Worse yet, we hear, the hashes weren't salted. The situation is probably both better and worse than it would appear; in any event, it's more complicated. more

Can Big Companies Stop Being Hacked?

The recent huge security breach at Sony caps a bad year for big companies, with breaches at Target, Apple, Home Depot, P.F.Changs, Neiman Marcus, and no doubt other companies who haven't admitted it yet. Is this the new normal? Is there any hope for our private data? I'm not sure, but here are three observations... This week Brian Krebs reported on several thousand Hypercom credit card terminals that all stopped working last Sunday. Had they all been hacked? more

Ethical Hacking: Turning The Tables to Boost Cyber Security

Hacking remains a huge problem for businesses. As noted by MarketWatch, more than 175 data breaches have already happened this year, and in 2015 approximately 105 million adults in the United States had their personal information stolen. For companies, the stakes are huge: Compromised systems not only damage the bottom line but can severely impact public opinion. more

“Capacity” - The Hidden Word?

What is so secret about the word, "Capacity"? As I read and talk with people I realize the word, "capacity" is typically missing from the DNS discussion. "Capacity" and "Security" are the two cornerstones to maximizing DNS resilience; both of which are typically missing from the DNS discussion. Have you seen a single DNS node easily process over 863,000 queries per second? Have you seen a network routinely handle over 50Gbits/second in outbound traffic alone without breaking a sweat? more

Summary Report Now Posted of W3C/IAB “Strengthening The Internet (STRINT)” Workshop

Given that I've written here about the original call for papers for the W3C/IAB "Strengthening The Internet Against Pervasive Monitoring (STRINT)" Workshop and then subsequently that the STRINT submitted papers were publicly available, I feel compelled to close the loop and note that a report about the STRINT workshop has been publicly published as an Internet-draft. more
