Root Certificate update and software design

Recently, a member of PISA (also called Anthony) noticed that when using HK Post office website, FireFox displayed security warning saying the digital certificate used bu HK Post is invalid.
A detailed study by other PISA members showed that the reason HK Post (once is the root CA for HK) used their own root certificate. Root certificates are usually shipped with the browser installation and HK Post digital certificate was not included in their default software package. Hong Kong Post setup a page to teach users on how to add the root certificate to most used browsers . However, how many users know this link, willing to follow or could follow the instructions !!
It is quite clear that currently most browsers develop and distributed by US company or US-based community. The interest of adding other root certificates is likely lower than adding new functions. Having said that, FireFox developers have a process to add Root Certificates to their software package, for example this link shows the process for adding root certificate. In their pending lsit, China PRC "China Internet Network Information Center (CNNIC)", Hongkong Post and Taiwan Chunghwa Telecom (CHT) are listed.
Entry for HongKong post was added on 2008-10-08. However, it is interesting to see that Mozilla used their bug tracking system in their handling for Root Certificate Request from CA around the world. Look at the email trails from e-Mice ( Hong Kong PKI operator)
The first request was submitted by HK Post Staff back in 2007 Dec and 20 months passed, it was not yet included in the latest FireFox update !! Obviously, FireFox needs to handle request from many different parties but it was a long time.
Maybe, we could look at the how Adobe do it. Within their design, "Adobe products that support the AATL will automatically download this file every 90 days.(1) Before the contents are deposited into the client's Trusted Identity list, the AATL is verified to ensure it came from Adobe. " The approval process may still take a lot of administration time, roots certificate updates will be 90 days. It is a lot better than waiting for a bug-fix or software release!!
My comment is all comes down to good design and bad design!

New models on generating revenue from losing newspapers
I read an article about how a group of US newspapers plan to respond to failing revenue.
1st : considered a “presentation on technology/service to track content on the Web and to extract payments from third-parties and ad networks that have appropriated newspaper content.” If other online formats are stealing your copyrighted content, make them pay for it.
2nd Collecting enhanced online newspaper user data across newspaper properties and mining that data to aggressively sell target content to specific audience segments across the network.”
The core tech are tracking content (1st model) or user behavior (2nd model). But it is not technology that matters. It is the law that gives the newspaper to charge or sell these data that affect its success. The copyright law enforcement is tooooo expensive compare to maybe HKD 10 for a single reference. Privacy law is too restrictive for newpapers to sell their DB.
My personal opinion is that the current legal infrastructure prohibit QUALITY newpapers to profit. Internet enables instant, multi-media and around the clock FACTs reporting. But QUALITY news report need more than FACTs.
Bloomberg and Reuters are the only successful company as I see it.

Open Source has another dimension --J.P. Morgan's CDS Analytical Engine Available as Open Source
Available as Open Source; Increases Transparency in CDS Pricing
At the centre of our current financial crisis is the CDS (credit default swap). ISDA is the trade association which draft standard contract for CDS.
The market was unable to give a reasonable and authority price for CDS in recent months. The open source decision is to make the price of CDS more stable and being open source, each one could validate the price components (market risk, liquidity risk, credit risk, FX risk and
others)
Open source when taking a transparent perspective could help to stable a market in crisis.

It is conveninet to believe some activities (like visiting a particular type of website) will affected by economy. But would this correlation substanitable ? giving the fact that the web content changes constantly and new websites are created daily?

Top-level domain name and anthropology
They seemed unrelated but I wonder how people respond to an explosive growth top-level domain names. Top level domain names, like .com or .hk are limited and users accumulated a sense of trust after years usages. Will user trust citibank.bank more over citibank.bank ? or will user buy items from toyshop.com or toyshop.shop ?
What is missing in the current Internet infrastructure, after 10 years of development, is trust? How ICANN's proposal to open up top-level domain is helping to built trust in cyberspace ? The current status of DNS is far from satisfactory and phishing attacks are launched daily exploiting this weakness. Opening up top-level domain name for private registrations will create a new zone of chaos.

Building cultural walls in Cyberspace
Contrast this to Lawrence Lessig's "Code wants to be free" concept, we could see that multinational enterprises were using codes to control information flow. The force to from multinational enterprises is gaining strengthen because these companies expand their influence by acquiring companies (like Google acquired YouTube and the planning integration of Yahoo & Microsft)

ISP guideline on Cybercrime investigation released
Guidelines for law enforcement - service provider cooperation (adopted on 2 April 2008)
From this document, it could be see that there is a large gap between law enforcement and ISP on obtaining evidences. Both sides need to formalise their procedures (either request or giving evidences). If there is no force from the government or other external factor, I could see no reason for them to incur additional resource in this process.

homophily part II - Social Capital
http://freakonomics.blogs.nytimes.com/2008/02/15/is-myspace-good-for-society-a-freakonomics-quorum/
"social capital", a concept that describes the benefits individuals receive from their relationships with others.
Bridging social capital reflects the benefits we receive from our "weak ties" — people we don't know very well but who provide us with useful information and ideas.
As our social networks are becoming increasingly more geographically fragmented, social network sites are a useful way for us to keep in touch and seek social contact with our friends.
When many students begin university, they find themselves with a group of ready-made acquaintances. Given people’s preferences for people who are like them, it could be that friendship networks become increasingly homogeneous. Is this a bad thing? It might be if, by choosing potential friends via their Facebook profiles, it means that folk cut themselves off from serendipitous encounters with those who are superficially different from them.
Social networking sites are affecting the labor market as well, because recruiters evaluating young professionals applying for jobs are now hacking into applicants’ profiles, and making hiring decisions based on profile photos in which applicants are drunk or inappropriately dressed.
they devalue the meaning of “friend.” Our traditional notion of friendship embraces trust, support, compatible values, etc. On social network sites, a “friend” may simply be someone on whose link you have clicked.

Anonymous network will be popular
Most people think the network address (IP address) are useless and could not reveal the location or identity of individuals. However, most IP address is similar to telephone number and could be traced to specific organizations. This traceability enabled Wikiscanner (mentioned in the article) to find the editor of wiki.
There are some anonymous networks like Tor for people to conceal their identity. I believe the PR will continue their censorship on wikipedia with these anonymous networks.
It is sad that when truth is the battlefield between individual and large organisations.

Stealing credit card numbers via home Wifi network
The 23-year old defendant was caught since he had used his home address for online shopping and the police were able to trace the delivery records. His ignorance of fraud detection systems and traceability of online shopping transactions seems to suggest that he is not a professional criminal. There are lots of ways to use stolen credit card numbers, buying cash coupons and delivering to an unoccupied house's mail box are common.
According to statistics , credit card fraudis increasing and costs 3 billion USD in 2006, up from 2.7 billion in 2005. Different measures (like adding chips or using an online password) are introduced to protect credit card transactions. However, these new measures are not effective if the network layer is circumvented.
When a malicious user has installed hacker tools on a network, the protection mechanism on the online application layer may not work at all. Man-in-the-middle attacks using fake servers to intercept Internet traffic were the most dangerous.Traditionally, to set up a man-in-the-middle attack or eavesdropping network traffic, the hacker needs to have access to the victim's physical network. However, with the availability of a wireless network, this physical constraint is no longer an obstacle. If the victim uses a non-encrypted wireless network (According to 2006 PISA wireless survey, 45% of wireless networks were not encrypted ), it is relatively easy to obtain his Internet traffic and the personal information transmitted (credit card information being included).
If the wireless network is not encrypted and users uses it to carry out online transactions or send credit card number via email, there is a high risk of stolen credit card information just like the criminal cases described above. If 45% of individually established access points in Hong Kong are not encrypted, what are the percentages of users having wireless security knowledge or awareness?

DDOS attacks are getting more frequent
DDOS attacks are real and there were even reported cases on DDOS against a national body Estonia.
The scary thing about DDOS is the growing number of botnet . With the higher penetration of broadband internet, more computers will be connecting to the Internet 24x7. If the management of these computers is not done securely, they will be a breading ground for botnets and viruses. One area to pay special notice to is the growing trend of networked devices. Vetting machines, CD juke boxes and other everyday electronic devices are likely to be connecting to the Internet within the next 3 to 5 years. These devices will have a slim OS, but able to carry-out basic network activities, like ping and HTTP GET command. The sheer amount of these network devices will be a problem if the OS is not hardened.

Transfer files on P2P is an offence in Hong Kong
On 12 Jan 2005, officers from HKSAR Custom Department raided thedefendant's (Mr. Chan) home after tracking his address from an online forum. Mr. Chan he had uploaded 3 .torrent files on 10 Jan 2005 and 11 Jan 2005 to the forum and these enabled BT users to download copies ofmovies. In first instance, Mr. Chan was charged by virtue of section118(1)(f) of the Copyright Ordinance, Cap 528 and of obtaining access to a computer with dishonest intent, contrary to section 161(1) (c) ofthe Crimes Ordinance, Cap 200. But in the final judgement in the Court of Final Appeal, the 5 judges unanimously dismissed Mr Chan appeal andhe was convicted of 118(1)(f) of the Copyright Ordinance only.
This was a high profiled case and the HKSAR government launched propaganda on their determination on combating the copyright battle. Since charges was brought to the court in 2005, the number of BT seeds decreased in Hong Kong. It was a success and a few points must clarify.
First, back in 2005 the prosecution charged Mr. Chan with "obtaining access to a computer with dishonest intent". This charge was totally wrong and stimulated many critics on the legal ground ofthis copyright case. Mr Chan was using his own computer to store andupload BT files. There was no hacking or illegal access on thecomputer he owned. By bring this charges, the prosecution misused the law and most ridiculously was that the judge agreed this charges. In the Court of Final Appeal, both the prosecution and judges corrected this mistake.
Second, the criminal offence from section 118(1)(f) of the CopyrightOrdinance was enacted before peer-to-peer ever existed and yet this section was able to catch distributing infringed copies via BTnetwork. The major argument by the defendant was that the detail mechanism of P2P does not constitute "distributing" since Mr. Chan was passively waiting owner to locate the media files and there were nophysical medium exchanged, only electronic currents. The judgesdisagreed and said if (1) the infringing copies were created by thedefendant and (2) his action enabled others to obtain the infringingcopies (in any way technologies allows and with full knowledge), then the defendant's action falls into the definition of "distribution"under Copyright Ordinance.

Control points missed in Symantec
This morning I heard astounding news about Symantec. It released a faulty virus definition that deleted (or quarantined) two essential files on Windows XP (Simplified Chinese Version). The result was that around 3 millions computers were unable to start and must restore the deleted files from the original Microsoft installation CD. SANS and Sina confirmed this news. They claimed that only people who downloaded the updates from the Symantec China webpage between 01:00 a.m. and 02:30 p.m. on May 18th AND have MS06-070 installed on their computer were affected.
This incident has many implications. The one that worries me the most is that people will try to download these files on the web in order to repair their computers. The integrity of these files is in question (if they do not come from an authenticated source). A malicious hacker may plant a virus or backdoor in these system files and offer them in discussion groups. As an auditor, I always think of process control. There are actually two control points within the release process of a virus definition. The first one is the approval and verification process for adding a system file to their blacklist. System files are high- risk files since they impact the whole system, instead of a single application. The second control point is the testing of the definition before publishing to the public. Does Symantec test all their definitions with all versions of OS? It is an extremely challenging and costly task to release timely virus definitions and, at the same time, to have all OS versions tested (different languages, times, services packs). Although it is a costly testing process, the risk is too great to ignore.
There is always a lesson to be learned from mistakes. Hopefully, the whole anti-virus industry will benefit from Symantec's mistakes.

The root of China SMS-based Payment
I agree with the article's contention that ATM and POS are not the right products for Chinese farmers. The main reason is cost. While the annual income of the averagefarmer in China is below USD 2000, it is relatively costly to acquire and maintain an ATM or POS, which usually costs more than USD 20000. Apart from cost, there is also a trend in other countries of declining rates of ATM adoption. According to the BIS statistics, the number of automated banking machines per million inhabitants decreased by 1123 in the year 2000to 1069 in 2005.
However, the picture portrayed by McKinsey seems to be of the distant future. The China Union Pay website reports that there are 86000 ATM and 608000POS installed. In 2005 alone, the transaction volume was more than five billion RMB (USD 670 M). However, there are only 14 cities in China enabled with mobile payment and with only 2.7 million users.
One major type of money flow in rural China areas is the money transfer from workers in urban cities. Urban city like ShangHai and ShenZhen attract millions of farmer who go to work there and their wages are usually"carried or transferred" back to the villages. This type of transaction is the root of many rural payments. So, the critical success factor may not be in the branches of payments in rural areas, but inthe root of most payments, which is in the cities.

CFCA -- the China next payment infrastruture
The banks will share their fraud information with China Financial Certification Authority CFCA, which was found by the banks in year 2000. CFCA is a certificate authority (i.e. a PKI service provider) and from ChinaTechNew.com 25 banks uses their certificates in 2005.
If this alliance is successful and continues its development, I think CFCA has the potential to be the center of China payment network. A secure PKI is important, especially for using client-side authentications. When the banks establish a cross-banks PKI process and agreements, the payment network may function a bit like VISA in plastic card business. For China, the development and innovations are unlimited.

When there is no choice .. ...
The speakers concentrated on two major themes:
1 Criminalisation of infringing downloading
2 Requiring ISP to keep IP-to-Physical Address records
One important discussion item was that almost everyone acknowledged the fact that a viable business model is needed for substantial development of online contents. But when there is no widely adopted business model, legislations are considered necessary.
PISA is monitoring these developments and will submit our views to the government.

RFID ticket in China

What puzzling me is the ticket-checking in Photo 2. You could see there are two railway staff standing behind a gate to check passengers ticket. The narrow opening is to prevent people from passing the gate. Except the tickets embedded with a electronic circuit, very little has changed. The railway staff still need to validate passenger's ticket one by one. When a few hundred passengers passing through the small gate, one can image the chaos it created!
China being late in infrastructure investment projects are applying advance technologies but this example shows that the benefit of technology may not be realized.
Another puzzling issue is why do they need a RFID ticket for a one hour journey where 99% of passengers do not check-in their luggages !!
