Deep Packet Inspection: Big Brother Technology for ISP's

 

These 'big brother' or 'eavesdropping' technology has long been use by the military of the United States.

Notoriously known as Echelon, a remnant of the Cold War is now still being operated.

From Wikipedia:

ECHELON is a name used in global media and in popular culture to describe a signals intelligence (SIGINT) collection and analysis network operated on behalf of the five signatory states to the UK-USA Security Agreement (Australia, Canada, New Zealand, the United Kingdom, and the United States, known as AUSCANZUKUS).[1]

The system has been reported in a number of public sources.[2] Its capabilities and political implications were investigated by a committee of the European Parliament during 2000 and 2001 with a report published in 2001.[3]

On the civilian side, same technology have been deployed in the US or other countries to sniff packets in real time ~ big brother.

Michael Kassner wrote a very interesting article on Deep Packet Inspection and its potential abused by government through ISP's.

User's privacy is at stake here.

Anyone who uses the Internet needs to be aware of Deep Packet Inspection (DPI), its uses, and potential misuses. You may recognize DPI as what ISPs use to conform to CALEA, the U.S. government-ordered Internet wire-tapping directive. If that’s not enough, DPI, albeit behind the scenes, allows ISPs to block, shape, and prioritize traffic, which is now fueling the “Net Neutrality” versus traffic priority debate. So, what is DPI and how does it work?

So what is DPI?

DPI is next-generation technology that’s capable of inspecting every byte of every packet that passes through the DPI device, that means packet headers, types of applications, and actual packet content. Up until now, this wasn’t possible with IDS/IPS systems or stateful firewalls. The difference being, DPI has the ability to inspect traffic at layers 2 through 7, hence the “deep” in DPI. A simple analogy would be that of snail mail. IDS/IPS firewalls would be the mail sorters who just read the letter’s address, knowing nothing about the letter’s content. Inspecting Internet traffic from layers 2 through 7 would correspond to the person who actually reads the letter and understands the contents.

To recap, DPI allows people controlling the device to know everything, including the payload of each packet in the data stream. For example, if an unencrypted e-mail is scanned, the actual body of the e-mail can be reassembled and read. Nate Anderson wrote an excellent Ars Technica article “Deep Packet Inspection Meets Net Neutrality, CALEA.” The following quote appears in that article:

“Deep packet inspection refers to the fact that these boxes don’t simply look at the header information as packets pass through them. Rather, they move beyond the IP and TCP header information to look at the payload of the packet. The goal is to identify the applications being used on the network, but some of these devices can go much further; those from a company like Narus, for instance, can look inside all traffic from a specific IP address, pick out the HTTP traffic, then drill even further down to capture only traffic headed to and from Gmail, and can even reassemble e-mails as they are typed out by the user.”

Mr. Anderson also explains what happens at layer 7:

“Layer 7 is the application layer, the actual messages sent across the Internet by programs like Firefox or Skype or Azureus. By stripping off the headers, deep packet inspection devices can use the resulting payload to identify the program or service being used. Procera, for instance, claims to detect more than 300 application protocol signatures, including BitTorrent, HTTP, FTP, SMTP, and SSH. Ellacoya reps tell Ars that their boxes can look deeper than the protocol, identifying particular HTTP traffic generated by YouTube and Flickr, for instance. Of course, the identification of these protocols can be used to generate traffic shaping rules or restrictions.”

What makes DPI all the more impressive is that the packet analysis happens in real time, with data stream throughput approaching 20-30 Gb. See where I’m going with this? With no loss of throughput, ISPs are able to insert these devices directly in their data streams, forcing all traffic to pass through the devices. Procera, Narus, and Ellacoya are front-runners in development of this technology, having placed equipment throughout the world.

DPI’s potential uses

DPI technology is unique in that as of now it’s the only way to accomplish certain governmental security directives. DPI also has the potential to do a great deal of good. For example, DDoS attacks are virtually impossible to thwart. Conceivably if DPI were in place and configured correctly it would detect the DDoS packets and filter them out. Some more potential uses are listed below:

  • Network security: DPI’s ability to inspect data streams at such a granular level will prevent viruses and spyware from either gaining entrance to a network or leaving it.
  • Network access: DPI creates conditions where network access rules are easy to enforce due to the deep inspection of packets.
  • CALEA compliance: DPI technology augments traffic access points (TAP) technology used initially for governmental surveillance equipment.
  • SLA enforcement: ISPs can use DPI to ensure that their acceptable use policy is enforced. For example, DPI can locate illegal content or abnormal bandwidth usage.
  • QoS: P2P traffic gives ISPs a great deal of trouble. DPI would allow the ISP to instigate traffic control and bandwidth allocation.
  • Tailored service: DPI allows ISPs to create different services plans, which means users would pay for a certain amount of bandwidth and traffic priority. This one is controversial and affects Net Neutrality.
  • DRM enforcement: DPI has the ability to filter traffic to remove copyrighted material. There’s immense pressure from the music and movie industries to make ISPs responsible for curtailing illegal distribution of copyrighted material.

The above applications have the potential to give users a better Internet experience. Yet it wouldn’t take much mission creep to create major privacy concerns. I would feel remiss if I didn’t point them out and help everyone understand the ramifications.

Possible misuses of DPI

DPI is another innovative technology that has ISPs arguing with privacy advocates. ISPs and DPI developers are adamant that the technology is benign and will create a better Internet experience. However, privacy groups have two major concerns: little or no oversight and the potential for losing still more individual privacy. Many experts find the following uses of DPI to be especially troubling:

  • Traffic shaping: Traffic shaping is where certain traffic or entities get priority and a predetermined amount of bandwidth. With the increasing number of bandwidth-hungry applications, ISPs are having to make decisions on whether to increase available bandwidth with infrastructure build out or increase control of the existing bandwidth. Installing a DPI system is usually the choice as it’s cheaper and has a more predictable RoI. Albeit cheaper, it’s riskier, and I suspect that’s why the Net Neutrality debate is going on right now.
  • Behavioral targeting (BT): BT uses DPI technology for the sole purpose of harvesting user information anonymously (supposedly) and selling it to interested parties who use the information to create ads that are targeted to the individual.

Final thoughts

This is a very complex subject, having the potential to change everyone’s view of the Internet. An optimist would say that DPI will help enhance the experience, even producing  ads that are relevant to each individual user. Whereas a pessimist would say it’s “big brother” technology that only benefits ISPs. I don’t think anyone is sure how the Internet will look when the dust settles about DPI, but it should be interesting.

I hope that I was able to increase awareness of how ISPs using a DPI device can intercept, read, and interpret every one of your Internet-destined packets. An ulterior motive for explaining DPI is that in my next article I’d like to discuss behavioral targeting, a very controversial technology that uses DPI. I also want to discuss what, if any, options are available to prevent DPI from scanning your Internet traffic.

Microsoft: Forget iPhone; we're still No. 2 in business

The big(ger) dog gets growly

 

July 21, 2008 (Computerworld) Companies -- lots of them -- are still buying Windows Mobile smart phones, and Microsoft Corp. doesn't want to let iPhone mania make them forget.

During Microsoft's most recent fiscal year, 325 enterprises purchased at least 500 Windows Mobile phones, with many buying many more, said Scott Rockfeld, group products manager for the mobile communications business at Microsoft, in a Friday interview.

"From the armed forces to the U.S. Court System, people are not just trying Windows Mobile, they are buying them," Rockfeld said, in apparent reference to a statement by Apple Inc. CEO Steve Jobs last month that 35% of Fortune 500 companies were beta-testing the iPhone.

My opinion, the Iphone is a fun phone, still a toy for the kids. Big boys still prefers Windows Mobile smart phones.

Storm Worm - wrecking havoc across the planet

                                                                   

 

 

The Storm worm (not to be confused with W32/Storm.worm) was first discovered on 17th of January 2007. It was named by the finish company F-Secure and it is a trojan malware that infects Microsoft operating system. It spreads via email, with these headings:

  • A killer at 11, he's free at 21 and kill again!
  • U.S. Secretary of State Condoleezza Rice has kicked German Chancellor Angela Merkel
  • British Muslims Genocide
  • Naked teens attack home director.
  • 230 dead as storm batters Europe.
  • Re: Your text
  • Radical Muslim drinking enemies's blood.
  • Chinese/Russian missile shot down Chinese/Russian satellite/aircraft
  • Saddam Hussein safe and sound!
  • Saddam Hussein alive!
  • Venezuelan leader: "Let's the War beginning".
  • Fidel Castro dead.
  • If I Knew

    When an attachment is opened, the malware installs the wincom32 service, and injects a payload, passing on packets to destinations encoded within the malware itself. According to Symantec, it may also download and run the Trojan.Abwiz.F trojan, and the W32.Mixor.Q@mm worm.[10] The Trojan piggybacks on the spam with names such as "postcard.exe" and "Flash Postcard.exe," with more changes from the original wave as the attack mutates.[9] Some of the known names for the attachments include:[10]

    • Postcard.exe
    • ecard.exe
    • FullVideo.exe
    • Full Story.exe

    Microsoft Security Assessment Tool for Governments (MSATg)

    The Microsoft Security Assessment Tool 3.75G (g for government version) is a revised version of the Microsoft Security Assessment Tool (MSAT) developed by Microsoft’s Trustworthy Computing Group.  MSAT is comprehensive toolset to help security organizations within governments become more aware of the evolving security threat landscape that could impact their organizations.

    The tool employs a holistic approach to measuring security postures by covering topics across people, process, and technology. Findings are coupled with prescriptive guidance and recommended mitigation efforts, including links to more information for additional industry guidance. These resources can help maintain awareness of specific tools and methods changing the security posture of the IT environment.

    The new Microsoft Security Assessment Tool conducts an assessments focused on 4 primary areas:

    •       Infrastructure Security

    •       Application Security

    •       Security Operations

    •       People, Process, Policy

    After completing each Assessment, a detailed report of the results is available to review.

    The questions identified in the survey portion of the tool and the associated answers are derived from commonly accepted best practices around security, both general and specific. The questions and the recommendations that the tool offers are based on standards such as ISO 17799 and NIST-800.x, as well as recommendations and prescriptive guidance from Microsoft’s Trustworthy Computing Group and additional security resources valued in the industry.

    The MSAT v3.75g is now be available to SCP Participants.  The “g” version will remove the feature that allows for uploading and sharing the results with Microsoft and comparing those with other companies.  This version will have the added ability to compile results on a user agency’s own servers and compare results between departments. Also as a part of this version, we provide instructions on developing a standard baseline and how this standard baseline can be distributed to other agencies to conduct an assessment comparison.

    The MSAT 3.75G version is now available in the following languages:

    Canadian French, French, German, Russian, Italian, Spanish (Latin America), Spanish (Spain), Portuguese (Portugal), Portuguese (Brazil), Chinese (Simple), Chinese (Mandarin), Japanese, Swedish, Norwegian, Danish, English (US), and English (UK.)
