Webcast, on July 7, Maintaining PCI Compliance!

Please join me on July 7 for an informative webcast on Maintaining PCI Compliance! To register or attend, please go to: http://www.brighttalk.com/webcasts/4431/attend.

Now that Level I merchants have undergone a few annual Payment Card Industry (PCI) assessments (and Level 2 merchants are soon to be doing the same), they are addressing the realization that a mature, sustainable compliance program requires more than once-a-year rallying to prepare for, participate in, and pass an assessment. Daily operational focus and ongoing effort are vital to protect investments in compliance, manage risk, and minimize the business disruptions and costs associated with achieving and demonstrating compliance year after year. This presentation discusses best practices for building a compliance program that can be supported and maintained year-round while also alleviating the burden on IT staff. When implemented effectively, the practices can help your company mitigate risk, reduce costs, and boost confidence in compliance by developing a cohesive plan for ongoing PCI assessment, maintenance, and refinement.

Cracking a 200 Year Old Cipher

I have a half dozen books on Thomas Jefferson’s life, but this is a pretty cool story I had never heard before. The Wall Street Journal this morning has a story about a Professor Robert Patterson, who had developed what appears to be a reasonably advanced cipher, and sent an enciphered message to President Jefferson in 1801. He provided Jefferson with the the message, the cipher, and hints as to how it worked, but it is assumed that Jefferson was never able to decrypt the message. The message was only recently decrypted by Dr. Lawren Smithline, a 36-year-old mathematician who works at the Center for Communications Research in Princeton, N.J., a division of the Institute for Defense Analyses.

The key to the code consisted of a series of two-digit pairs. The first digit indicated the line number within a section, while the second was the number of letters added to the beginning of that row. For instance, if the key was 58, 71, 33, that meant that Mr. Patterson moved row five to the first line of a section and added eight random letters; then moved row seven to the second line and added one letter, and then moved row three to the third line and added three random letters. Mr. Patterson estimated that the potential combinations to solve the puzzle was “upwards of ninety millions of millions.”

After about a week of working on the puzzle, the numerical key to Mr. Patterson’s cipher emerged — 13, 34, 57, 65, 22, 78, 49. Using that digital key, he was able to unfurl the cipher’s text: “In Congress, July Fourth, one thousand seven hundred and seventy six. A declaration by the Representatives of the United States of America in Congress assembled. When in the course of human events…”

I am not sure why I am fascinated by this discovery. Perhaps it’s a bit like discovering hidden treasure.

Profile: Tufin Technologies

If you work in IT, then you have devices to manage. There is no escaping this fact. Often device management comes down to numbers and resources. How many devices are there to manage, where are they located, who has access to them, and what happens when someone in Chicago changes a policy, will that affect the office in Manhattan?

More Michael Jackson related attacks online

Several security vendors are issuing reports about Michael Jackson related Malware, either in the form of a mass-mailing Worm or search related domains that offer images. The aim is to use the shock of the pop star’s death to lure victims into downloading images, video, music, and news articles with the latest information. 

F-Secure, on Monday, discovered several domains that are spreading Malware related to the singer’s death.

Rebellion over an ID plan

bar_code_cow.jpg

What they were emphatically not doing, said Jay Platt, the third-generation proprietor of the ranch, was abiding by a federally recommended livestock identification plan, intended to speed the tracing of animal diseases, that has caused an uproar among ranchers. They were not attaching the recommended tags with microchips that would allow the computerized recording of livestock movements from birth to the slaughterhouse.

“This plan is expensive, it’s intrusive, and there’s no need for it,” Mr. Platt said.

The New York Times reports that not even cattle need Real ID in”Rebellion on the Range Over a Cattle ID Plan.” There’s a web site, NoNAIS.org which is tracking things like

Oklahoma is now mandating Premises ID for anyone wanting participate in the Swine Shows. One more tricky little way that they make “voluntary” into mandatory.

Firefox 3.5 to get first patch mid-late July

Mozilla is said to be planning a round of patches and bug fixes for their newly released browser version due later this month. As was the case during the 3.0 release, Mozilla released Firefox 3.0.1 just four weeks later, addressing several bugs and security issues.

The patches, coming only a few weeks after Firefox 3.5 was released to the public, will address what Mozilla calls topcrashes, or bugs that lead to consistent crashes in the browser.

Handling the Politics of NAC Policies

Network access control technologies are complicated enough to plan and implement on a technological level, but dealing with the politics of policies can be an entirely new headache your IT department never saw coming.

Conversations about NAC frequently start with basic information gathering: What features are you looking for? What operating systems and switches are in the environment? How do you want to handle non-compliant devices? And, of course, the sales guy will slip in the ol’ “What’s your budget?” line.

Take this set of Q&A with a grain of salt. When making decisions about NAC, there’s another set of primary questions that should be addressed first: What are the primary drivers for implementing NAC? What organizational policies need to be enforced? Where is your organization’s trade off between security and productivity?

The Technology of Policy

For the network administrators, IT directors and technologists these questions are the equivalent of that mandatory legal jargon in size 6 font on a page footer; superfluous at best and an impediment at worst. And so here comes the catch-22 we face in every NAC implementation — the struggle of finding the equilibrium between the policies of management and the technology of security.

When we talk about network access control systems, we start talking about segmenting, VLAN-ing, quarantining and isolating devices and/or users from the various network resources. We’re stopping users from accessing the Internet, we’re stopping laptops from accessing the primary database servers and maybe we’re even preventing a critical billing or HR system from accessing the resource it needs to cut the weekly paychecks. We are, as technologists, implementing a control that will, in effect, be playing God on the network.

And yes, I know the prospect of total supreme network domination is exceptionally appealing to you all. Aside from sounding cool, it does give us complete purview over the network and control over any objects that may become security risks for the organization. For those of you who have spent your entire career protecting the network from dumb users and protecting those same dumb users from themselves, NAC can be a key tool for you; however, implemented without controls and proper planning, it can also be the bane of your (and everyone else’s) existence. Why? It’s pretty simple, the first time a critical system or critical employee gets zapped from the network, either you or your NAC solution will disappear — and quickly.

I get dirty looks every time I say this, but it’s true - network access control is a BUSINESS DECISION, not a technology decision. We put the technology in place ONLY for the purpose of supporting and enforcing an organizational policy that is already in place. When organizations do it the other way around and start making policies around the technology, they’ve doomed the project before it began.

There are a host of reasons to not set access policies Willie-nilly on the network. Aside from the obvious ones, there’s an assortment of legal and business reasons to hold off on total network domination. In this age, the IT department is forced to take into account such off-the-wall issues as human resources policies, compliance and regulation mandates, corporate initiatives and even partner contracts. What if one of your newly imposed NAC policies conflicted with a primary policy or standard for operation and violated your organizations HIPAA or SOX compliance? What if you cut off a partner resource that was contractually provisioned with an uptime guarantee? Or what if the policy you set is simply not enforceable by the HR department?

Five Steps for a Successful Start

If NAC is something your organization’s management recognizes as a necessity and has signed off on, then you’re heading down the right path and there are some key things to consider in a successful NAC rollout.

  • 1. REVIEW your organization’s current policies on network resource usage, access and enforcement. If they need to be updated or rewritten, do that first and then continue with your project.
  • 2. IDENTIFY, ORGANIZE AND CATEGORIZE key resources, devices and users. You don’t want to cut off your arm if your finger is bleeding, and for some users, you don’t want to ever cut off anything. Understanding the key pieces in the network is the first step to matching your NAC policies to the real policies.
  • 3. MAP the NAC policies to your organization’s usage policies. That’s why we do step 1 first. If users in Group A aren’t allowed to Resource X, in Circumstances C, D or E, then make it happen that way. If a device is critical, exempt it from enforcement policies and only monitor and audit it.
  • 4. START slowly and monitor first. Most NAC solutions offer a monitor-only function that allows you to create policies and then determine which systems would pass or fail based on the current posture of the devices — without actually enforcing any restrictions. Monitoring lets you ease in to the solution, identify non-compliant devices and fix them before your help desk (or your cell phone) is inundated with calls from end users.
  • 5. RINSE AND REPEAT. NAC policies need adjusting as endpoints, programs and the Internet changes and evolve. New threats and new organizational goals are always on the horizon, and the only way to prevent stale and useless policies is to stay on top of them.

Pornography, government and the Internet

It’s probably superstition, but it seems that news stories comes in bunches. Today’s theme is: “governments across the planet try to deal with Internet pornography”:

– The Green-Dam saga continues. China delayed indefinitely the requirement that new computers have an installation of Green Dam-Youth Escort filtering software to protect young people from pornographic and violent Internet content. The big question seems to be: “will the delay be temporary or permanent.” They really should just make the filtering voluntary AFTER they get rid of the political censorship issue and AFTER they resolve the copyright-infringement issues and AFTER they fix the vulnerabilities in it. But I digress.

– The Ukraine has made illegal the possession of pornography except for medicinal purposes. I just don’t know what to say about “medicinal purposes” except that it’s going to generate another category of spam that will probably give a whole new meaning to “Canadian pharmacy.”

– In the U.S., several adult-content web sites appear to be collateral casualties of the take down of the Pricewert ISP by the Federal Trade Commission. Some are reporting the loss of $5,000 per day. Some are scrambling to find their web site content, since the Federal court and FTC confiscated Pricewert’s servers. I guess the lesson here is: don’t do business with businesses that do illegal stuff.

– The Georgia (USA) Bureau of Investigation is warning that an email containing a six-minute child porn video is circulating in the Stone Mountain area. The video may be might be a 2005 clip from the Dominican Republic that has been known to investigators. There are conflicting news reports, but at least one says it’s being spammed by malware. Possession of the video on one’s computer is a felony in the U.S. Investigators are telling Internet users to delete the email on sight (Subject line: “VERY Disturbing! TAKE CARE OF YOUR KIDS/ they should kill this man, do not open if your [sic] sensitive… click video link.” )

Pornography has been a complicated issue since, well, forever. There are paintings in the ruins of Pompeii of “adult” nature that were buried in the year 79. In the quaint 1950s in the very Puritan U.S., there were “nudist” and “art photo” magazines that pushed the legal envelop and “men’s” magazines explored how much of a woman’s anatomy they could show and still stay at least one millimeter away from the legal limit.

In the U.S., porn enthusiasts probably won the battle when courts as high as the U.S. Supreme Court found themselves completely unable to define the difference between pornography and free speech. In 1964, U.S. Supreme Court Justice Potter Steward wrote the legendary articles of surrender, saying that he couldn’t define pornography, but “I know it when I see it.” Shortly after that, the VCR went on sale and it was REALLY “game over” for the anti-porn side.

The result has been a legal shadow world and very lucrative gray economy that turned into a terrific environment for scams, fraud, rogue anti-malware products and thieving computer malcode. Yes, there is a load of pornography out there on the Internet that is perfectly legal, sold by perfectly legal businesses with secure servers. Governments in conservative places will always try to fight it. They will only ever have very limited success. Sex will always be a very shiny lure.

The bottom line: if you see any advertisement on the web or in your email for “adult” anything, it simply will never be truly safe to go there.

Michael Jackson X-Files Answer

Yesterday, amid the heavy Michael Jackson news coverage and tabloid autopsy speculations, another round of email was spammed out with the following text:

Michael Jackson Was Killed…
But Who Killed Michael Jackson?
Visit X-Files to see the answer:
(hxxp://xfiles link here)

The link redirected to a site hosted at 87.97.116.131 in an x-file-esque directory “x-files/x-file-mjacksonkiller.exe”, which is currently down. The site hosted a malformed pdf and Zbot banking password stealing variant. The ThreatFire community prevented the file in very low prevalence, so very few users are falling for this sort of shameless scam. But we remind you to always think twice before running an unknown executable or visit an untrusted site (the url for this one is most likely not a domain one would recognize: jillih. com), regardless of the news. And update third party plugins on your system like pdf readers.

Is AES secure enough?

There’s been a lot of discussion in the past day or so about the security of the AES encryption algorithm. There’s a paper by Alex Biryukov and Dmitry Khovratovich that describes an attack against AES-256 that can be done in much less time that brute-force exhaustion: 2119 trial encryptions instead of 2256. That’s a huge difference. Is AES now so weak that we need to worry about it?

Absolutely not.

The attack that Biryukov and Khovratovich found also takes lots of data for it to work. Their attack that can be done in 2119 time also takes the same amount of data: 2119. That’s a lot of ciphertexts.

The best estimates that I’ve seen say that the entire world produces a few exabytes of data per year. This estimate is actually from a few years ago, so it isn’t that current. Let’s suppose that the amount of data being created doubles each year. If that’s the case, we probably have a few zettabytes of data being created per year right now.

A zettabyte is 1021 bytes, or about 270 bytes. That’s a lot of data, but it’s still a long way from 2119 ciphertexts. This means that an attack that takes that much data is totally impractical. Even if we assume that all of the data in the world is being used in an attack that’s trying to recover a single AES key, it’s still not enough. It would take roughly the amount of data that the entire world will produce in the next 50 years or so to get the amount of data that we’d need. And even then, the amount of time required is still prohibitive.

It’s interesting that Biryukov and Khovratovich found a significant weakness in AES, and their work may give useful insights into how to design better symmetric encryption algorithms, but it’s not the sort of weakness that anyone can actually use to actually recover data that’s encrypted with AES.
