11 [Tech Info] Biometric Technology to be introduced into Passport
----------------------------------------------------------------------
Do you know "Minority Report" starring Tom Cruise? It is a movie about
future society, where irises of all humans are registered for
identification, in 2054. In this movie, there is a shocking scene of
eyeball implantation in order to spoof as another person. Like this,
the authentication technology by "unique and unchangeable" living body
feature is called "Biometrics."
Biometrics is going to be introduced for preventing forged passport.
International Civil Aviation Organization (ICAO) started an argument
which biometric technology should be selected from face, fingerprint,
iris, signature, voiceprint, or shape of palm in the late 1990s, and
reached the conclusion that face is adopted for ePassport.
Based on the international conclusion, Japan is planning to start to
issue an ePassport in March 2006. The image of face will be saved in
an IC chip of each passport. Since face is changeable compared to
fingerprint, authentication accuracy falls off with time. However,
after research studies, it is verified that accuracy can perform for
10 years, which is an available term of passport, with validity. A
development of guideline for photography has already started, and it
is expected to improve accuracy more.

13 [Tech Info] The Report 'Trends in Enterprise Architecture' 2005
----------------------------------------------------------------------
Institute For Enterprise Architecture Developments(IFEAD) is a
research and information exchange organization working on the future
state of Enterprise Architecture. This organization has a Website
which provides us with a lot of valuable information of Enterprise
Architecture(EA).
URL: http://www.enterprise-architecture.info/index.htm
You can obtain information about EA standards, EA methods, EA tools,
EA & strategy, EA best practices, EA governance, EA education, and so
on from this website. And also this website has links to other various
EA websites which help us plan and implement EA.
IFEAD conducted survey on trends in EA. This survey is a part of a
yearly recurrent survey to measure the progress and developments in
EA. The survey is based on a 25 question questionnaire such as "Why is
EA important for your organization?", "For what kind of issues do you
plan an EA program?", "Is your organization familiar with the
importance of EA?", "Is EA part of your organizations strategic
governance?", "At which level is EA part of your organizations
governance structure?". IFEAD analyzed the result of those
questions. This report guides you through the latest trends of EA by
referring to the report.

14 [Tech Info] "Windows Vista" Coming Next Year
----------------------------------------------------------------------
(1) "Cheetah", "Jaguar", "Panther", "Tiger"
(2) "Chicago", "Memphis", "Whistler", "Longhorn"
Can you guess what they mean?
(1) is a list of large cats, well known project code names of Mac OSX.
("Cheetah"=Ver.10.0, "Jaguar"=Ver.10.2, "Panther"=Ver.10.3, "Tiger"=Ver.10.4).
(2) is a list of project code names of Microsoft Windows OS named after place names.
("Chicago"=Windows95, "Memphis"=Windows98, "Whistler"=WindowsXP, "Longhorn"=WindowsVista)
Traditional image of code name is like a secret code informally given
to the project under development and used within the organization. But
these days, some major computer companies like Microsoft, Apple,
Intel, announce their project code names to the public and they are
widely used till the official product names are published.
In July 2005, next version of Windows OS got their official name
"Windows Vista" and project code name "Longhorn" finally completed its
role. The code name "Longhorn" was so common to the public users
because debut of the new version had been eagerly hoped almost five
years after the current version of Windows XP was released in 2001.
Despite its debut originally planned in 2004, development schedule was
revised several times and according to Microsoft's recentannouncement,
"Windows Vista" for consumers would be launched in January 2007.
"Vista" means vision. Microsoft said that the name "Vista" had the
sense of bringing clarity, so it was expected to make things clearer
and pretty simple. "Windows Vista" emphasizes security function, more
flexible searching function and more sophisticated user interface
compared to WindowsXP. (Incidentally, "XP" means experience.) "Windows
Vista" consists of six editions, "Starter 2007," "Home Basic," "Home
Premium," and "Ultimate" for home and "Business" and "Enterprise" for
business, to cover all the segments of users.
This Windows OS development project spent a long hard period as
"Longhorn." With the official name "Vista," will Windows OS acquire
clear vision and bright future?

15 [Tech Info] Wireless LAN Today
----------------------------------------------------------------------
Nowadays many organizations tend to adopt the wireless LAN in addition
to their LAN. By using the wireless LAN, it becomes easy to construct
LAN and reallocate the computers connected to it.
There are three major types of the wireless LAN specification as follows:
a) IEEE802.11a : MAX 54Mbps (speed), 5 GHz
b) IEEE802.11b : MAX 11Mbps (speed), 2.4GHz
c) IEEE802.11g : MAX 54Mbps (speed), 2.4GHz
The user will select the appropriate types of the wireless LAN above
according to their network usage and the compliance of the Radio Law
of each country.
In addition to the above three specifications, IEEE802.11n is now
under discussion to make available to the public and this may become
one of the main stream of wireless LAN in few years.
Main characteristic of IEEE802.11n is in its higher network speed.
The maximum speed of current wireless LAN is 54Mbps, whereas that of
IEEE802.11n is approximately up to 300Mbps. This improvement of the
speed is so drastic, it is almost more than six times of the current
network speed.
IEEE802.11n mainly adopts the following advanced technologies to
improve the network speed and smooth data transmission:
1) to increase the number of antennas
IEEE802.11n uses the technology called 'MIMO (multi input and multi
output)' and can accept the data transmission from four antennas
simultaneously. This means that data can be transmitted four times
faster than before.
2) to improve the data transmission efficiency
IEEE802.11n minimizes the unnecessary data length and reduces the
interval time for data transmission. The volume of data will be
increased by approximately 140% by this technique.
3) to utilize wider bandwidth
The current bandwidth range is 20MHz and it will be doubled up to
40MHz. Therefore, the network speed of IEEE802.11n will be upgraded
as:
(54Mbps) x (2) x (1.4) x (2) = approximately 300Mbps
The specification of IEEE802.11n is scheduled to be fixed by March, 2007.

16 [Tech Info] New features of J2SE 5.0
----------------------------------------------------------------------
J2SE-Java 2 platform, Standard Edition 5.0("Tiger") released in
Sep. 2004 was made various improvements.
For details, see http://java.sun.com/j2se/1.5.0/docs/relnotes/features.html
Major concepts of J2SE5.0 are as follows.
(1)Ease of Development
(2)Performance and Scalability
(3)Monitoring and Manageability
(4)Desktop Client
(1) is the concept to aim for simplification of development by extending the Java programming language.
(2)-(4) are the concepts to aim for robust execution environment. We
focus on "(1)Ease of Development(EoD)" in this article.
New feature categorized as EoD are as follows.
- Generics-Add Generic Types to the Java Programming Language
- Extending the Java Programming Language with Enumerations, Autoboxing, Enhanced for loops and Static Import
- Metadata (A Metadata Facility for the Java Programming Language)
Let's see familiar for loop this time.
We describe code to handle array or collection as bellow.
----------Case 1:Array----------
String[] str = new String[3];
str[0] = "one";
str[1] = "two";
str[2] = "three";
for(int i = 0; i < str.length; i++) {
System.out.println(str[i]);
}
----------------------------------
----------Case 2:Collection----------
Collection str = new ArrayList();
str.add("one");
str.add("two");
str.add("three");
for(Iterator i = str.iterator(); i.hasNext()) {
System.out.println(i.next());
}
----------------------------------------
We have to declare index or iterator for each "for loop".
When we use "Enhanced for loops", we can code simpler.
----------Case1----------
for(String s : str) {
System.out.println(s);
}
---------------------------
----------Case2----------
for(Object o : str) {
System.out.println(o);
}
---------------------------
Like this, you can define your code simpler and eliminate bugs as a
result. Please try to make a simple and readable program with adopting
Java evolution.
----------------------------------------------------------------------
17 [Tech Info] Biometrics - Vein authentication
----------------------------------------------------------------------
Recently biometrics is getting introduced in Japan. This topic is vein
authentication, which is a kind of biometrics. Vein authentication
uses a blood vessel to identify each person. (Not capillary vessel but
thick and stable one.) Even twins do not have the same pattern of
veins. And since vein pattern is biometrics information, we can not
get the information by photo and contact.
According to a certain Japanese manufacture's report, the ratio of
identifying an original correctly is more than 99.99%¡¡and the ratio
of identifying others incorrectly is less than 0.00008%.
Progress of Vein Authentication for public use is as follows:
Vein authentication started working at major banks in Japan in the
middle of 2004. In 2005, it started working by little and little in
university hospitals, condominiums and houses. A certain university in
Tokyo is using it as the student identification. This is a rare case.
In 2006 , Japanese government passed the law which requires a bank to
indemnify a customer who suffered damages by stolen or forged bank
card. That is why financial institutions are forced to increase their
security level. Vein authentication is getting introduced especially
in financial facilities against social background like this.
----------------------------------------------------------------------

19 [Tech Info] Information leakage caused by Winny
----------------------------------------------------------------------
In Japan, computers using "Winny", a most popular file-sharing
software, have become widely infected by several warms, and then such
incidents that confidential files are flowed out in Winny Network have
happened quite often not only from the computers of individuals or
private companies but also from the ones of public institutes such as
a police station, Self-Defense Forces, Japan Post, a jail, a court, a
nuclear electric plant, a local government, and public offices. It's
because workers bring back home individual information treated in
their work, and those sloppy managements have been criticized very
much.
Winny is a P2P (Peer to Peer) file-sharing program developed by a
Japanese, while Napster, Gnutella, WinMX, and Share are known as
common typical file-sharing programs. A file-sharing software is
originally a tool for exchanging sound files and video files which are
too large to exchange via e-mail and web. This idea itself is not
illegal, but most files traded are copyrighted files, which makes us
difficult to tell whether the software is evil or not.
Let's see how Winny works actually. When a user put a file in a
specified upload folder, it will be copied to his/her Winny share
folder, which is connected to Winny Network. When other users download
it, it is copied to their Winny share folder too. As this downloadings
done so many times, files spread out among a lot of computers then
nobody can tell when and who first put it into the public and where
the files exist physically.
Information leakage happens by being affected by a virus. This virus
comes in sometimes via e-mail, but mostly via Winny Network as an
attachment of an illegally shared file. When you open the file, your
computer will be affected by the virus. The virus copies the contents
of your computer or your mail and exposes them to Winny Network.
Once a file is exposed in Winny Network, it is downloaded by many
people and it becomes impossible to reclaim all the copies of it
because of the anonymity of Winny Network. When the incident
broadcasted as a news, some people are even willing to download such
files to enjoy the party's suffering.
Let's consider what kinds of countermeasures are effective.
There are two major countermeasures. One is to disable starting Winny
by using an OS function to forbid the execution of an application. If
your computer is Windows XP, you can disable starting of Winny by
specifying in "Local Security Settings" the filename of Winny
"winny.exe", or its hash value.
The other is to block off Winny from your network. To restrict the
network utilization by setting a filtering function of the firewall is
effective for such a network whose client computers can communicate
with limited hosts. For example, if a client computer accesses the
Internet through a specified mail server, a DNS server, or a proxy
server, you can allow only the proper use of the Internet and cut off
the other use by setting on these servers. If client computers use
those softwares like Skype which communicate directly with multiple
hosts at once, you have to analyze the traffic pattern of Winny or
introduce a device which deciphers and cuts off communication.
Not to mention Winny, any file-sharing software always goes with the
danger of information leakage. It is quite important to establish a
security policy in your organization and take measures such as "Do not
bring business data out from the company", "Do not install Winny in
your home computer", and "Configure client computers not to allow
running Winny". Please be sure to take care.
For more detailed information on Winny, see this site.

20. [Tech Info] Samba 4.0 New Release October 2006
----------------------------------------------------------------------
When sharing file documents, Samba package is often used and very
popular in Linux environment. And now, Samba is going to release an
attractive version. While the stable version is Samba 3.0 at present,
a new version, Samba 4.00tp3 has just been released on October 16 this
year. Here please note that the version "tp" is called Technology
Preview, which means it is not stable version, but absolutely just for
verification or examination. Therefore, the "tp" version can't be
installed into a real system.
The main attraction of Samba 4.0 is to realize Windows Domain
Controller and implement the related protocols. In order to control
Windows PCs, Active Directory is mainstream nowadays. The current
version Samba 3.0 has compatibility with Windows NT domain, however it
can't be an Active Directory Domain Controller by itself. Samba 4.0
performs as an Active Directory Domain Controller which Windows PCs
can belong to.
Furthermore, it has the following features.
- NTVFS implementation
While Samba 3.0 has no compatibility with Windows file system,
Samba 4.0 implements NTVFS, which provides almost same features as
NTFS.
- LDAP and Kerberos integration
Samba 3.0 needs to utilize external packages for LDAP and Kerberos,
but Samba 4.0 has built-in functions for those.
Notice
- It doesn't have built-in functions for DNS, so needs to work with
BIND.
- It doesn't provide a GUI management tool.
This is a good opportunity to verify the new Samba, why don't you try
it? Samba 4.00tp3 is available from the following website.

1 [Tech Info] ISO/IEC 27001:2005(ISMS Standard) Has Just Been Published
----------------------------------------------------------------------
ISO/IEC 27001:2005 has just been published on Oct. 15, 2005. It
replaces BS 7799-2:2002 (UK Standard). ISO/IEC 27001:2005 is a
management standard, which explains how to build, maintain and improve
an Information Security Management System (ISMS). It is based on risk
assessment and Plan-Do-Check-Act (PDCA) model. The standard provides a
specification for ISMS and the foundation for third party audit and
certification. It is harmonized to work with other management system
standards such as ISO 9001 and 14001.
"'The publication of ISO/IEC 27001:2005 is a big event in the
world of information security and the standard has been eagerly
awaited,' said Ted Humphreys, Convener of the working group
responsible for managing the development of the standard. 'It is a
standard that all security-conscious organizations should look to
implement.'"
http://www.iso.org/iso/en/commcentre/pressreleases/2005/Ref976.html
In addition to the development of ISO/IEC 27001, ISO/IEC JTC1 SC27 is
working on several other standards that will all be included in the
27000 series of standards - in analogy to the management system
standards, such as ISO 9001 and 14001.
The standards in the 27000 series are:
- ISO/IEC 27000: Information Security Management System Fundamentals
and Vocabulary (under development)
- ISO/IEC 27001: Information Security Management System - Requirements
(published)
- ISO/IEC 27003: Information Security Management System Implementation
Guidance (under development)
- ISO/IEC 27004: Information Security Management Measurement (under
development)
- ISO/IEC 27005: Information Security Risk Management (under development)
The integration of ISO/IEC 17799:2005 into the 27000 series will be
discussed and decided upon in spring 2007; a forward in ISO/IEC
17799:2005 is explaining this situation, and if ISO/IEC 17799:2005 is
integrated into 27000 series, it will obtain the number ISO/IEC 27002.
There is ISMS Conformity Assessment Scheme based on BS 7799-2:2002 in
Japan. Security Course participants studied details in "Making ISMS",
and all participants studied a little in "Security Basics". This
scheme will be revised in 2006, based on ISO/IEC 27001:2005.
----------------------------------------------------------------------
2 [Tech Info] PMP(R) Credential Exam System Changes
----------------------------------------------------------------------
On September 30, 2005, Project Management Institute (PMI(R))
officially revised Project Management Professional (PMP(R)) credential
examination. PMP is a credential awarded by PMI and currently the
number of PMP holders amounts to 50,000 all over the world.
The major changes in the exam are as follows:
- The new exam is based on "A Guide to the Project Management Body
of Knowledge (PMBOK(R)) Guide Third Edition", while the old exam
was based on "PMBOK Guide 2000 Edition".
- The passing score is 106 questions correct out of 175 scorable
questions (61 percent) , while it used to be 137 out of 200 (69
percent) in the old exam.
PMP exam can be taken in over 60 countries. Among the countries which
PMA Course participants belong to, Bulgaria, China, Indonesia,
Philippines, Romania, Turkey, and Uzbekistan have testing centers for
this certificate.

3 [Tech Info] GUI or CUI?
----------------------------------------------------------------------
There are two types of well-known user interfaces. One is "GUI
(Graphical User Interface)" and the other is "CUI (Character User
Interface)". GUI enables users to make operation more easily by using
graphics such as icons, buttons and pointing devices. On the other
hand, CUI prepares character-based interface such as terminal screens
and users input from keyboards.
Nowadays it seems that GUI has become mainstream not only for Windows
users, but also for UNIX/Linux users. Users do not have to memorize
and type the commands. It is good for beginners because anybody can
intuitively make operation with mouse click and visual guidance.
A young application specialist Y-san, who is a typical GUI user, says,
"I hate command. I hate terminal screen. I hate keyboard typing. Why
should we do such old aged operation in the era of GUI? We have many
useful tools and can make applications by drag and drop. It's enough!"
However, there remain persons who still love commands. Most of them
are very skillful developers, but they usually shut their heart to the
GUI world. A genius engineer O-san, who is an extreme command lover,
says, "If you like GUI, it's OK. Whatever you want. I do not want to
waste my time caring amateurs like you."
Why do they adhere to commands and never change their way? The answer
is easy. GUI is efficient only for the easy work, but for the complex
work, CUI has the great advantage. For example, if you want to put
extension ".oic" to all the files in your PC whose names include
"okinawa" and are updated in half a year, using command is far simpler
than using GUI.
K-san, the command analyst says, "Commands are represented by pure
text format so you can grasp all the system configuration as a
string. It means you can make the perfect reconfiguration of your
settings. Being represented by text format enables you to do iterative
operations using such technique like copy-and-paste, and/or
functioning."
If you are a typical GUI lover, try to use command sometimes. It will
make your work easier and more comfortable!
----------------------------------------------------------------------
4 [Tech Info] Skype Technology
----------------------------------------------------------------------
Skype, the Internet telephone software released two years ago, now has
over 60 million users in the world.
The reason of its popularity is the voice communication quality, which
is the same level as ordinary telephone. Therefore, users do not feel
stressed while talking. Another reason is that this service is free of
charge if used in PC-to-PC communication. You have to pay if you call
from Skype to ordinary telephone, however, the communication charge is
far less than that of ordinary telephone.
The inexpensiveness of this service comes from the low cost of the
service provider's facility. Normally, telephone service is provided
by expensive circuit switches owned by telephone companies. However,
Skype owns only the servers to manage their user accounts and
authenticate them. The other functions such as controlling calls are
allocated to users' computers dispersedly using P2P (peer to peer)
technology.
So far, this software is mainly for personal use, however, gradually
it has gained popularity among the companies that seek for lower
communication costs. Also it may become a key-application to integrate
telephone network into LAN.
The latest version of Skype supports video chat, which can be applied
to video conferences in companies. If you are interested in Skype,
please try to access the site below.

6 [Tech Info] New Computer Viruses Increase by 48% in 2005
----------------------------------------------------------------------
Sophos Co. has published the report concerning the damage of computer
viruses in 2005 on December 6th. According to this report, the number
of new virus/worm identified by Sophos Co. during 2005 was 15907.
This figure shows an increase of 48% over the previous year.
"W32/Zafi-D" worm has caused the biggest damage. "W32/Netsky-P" virus,
the previous year's hardest hitting virus, has dropped to second
place. "W32/Sober-Z", just unleashed in November 2005, has already
risen to third place. The report also identified that one in every 44
e-mails has viral in 2005.
The number of new computer viruses increase year by year.
Countermeasures against malicious software becomes more and more
necessary to avoid damages. As all of you know, installing anti-virus
software is important, but it's not sufficient.
Why don't you review your daily operation when using computers?
1. Don't open email-attached files without checking its safety.
2. Don't use preview window on MUA.
3. Check computer viruses when sending any files by using e-mails.
4. Maintain the latest pattern file in anti-virus software.
5. Check new security patches information.
6. Make backup files regularly.
etc....
These should be documented as rules. How about your organization?
The top ten viruses of the year,reported at Sophos' global network of
monitoring station, are as follows

7 [Tech Info] If you understand yourself well, you can communicate well.
----------------------------------------------------------------------
You all studied "Coaching skills" in Leadership Training. Do you use
coaching skills in your daily life? If you say that you use them
everyday, that is great! Please keep doing. But if you say, "I can't
use coaching skills because colleague's ideas are not good.", "There
is no enough time for coaching session.", or "I have to teach correct
way of doing.", maybe you are right. Your idea can be much better than
their idea.
I would like to remind you that people are not willing to commit to
other's
idea very much comparing with their own ideas. You should give your
proposal in manner that they can accept easily.
Today I introduce you the "enneagram", a study of personal growth
based on ancient teachings. The enneagram describes nine distinct
personalities. Knowing your own personality type, you will understand
"your way of thinking" and "others might have different way of
thinking". Since your colleagues might have different personality
types, it is good to use different communication style for better
understanding of your proposal.
Please visit http://www.enneagraminstitute.com/ and try The Free RHETI
Sampler to know your personality. After taking the sample test, they
give
you advice. You can find another explanation in http://www.ennea.com/.
People have different personalities but it doesn't mean they are better
or
worse. I hope you will use enneagram and enjoy better communication.

8 [Tech Info] Next Generation of Microsoft Excel
----------------------------------------------------------------------
Currently, the Microsoft Corporation is developing a new version of
Microsoft(R) Excel, under the code name of "Excel 12." This software
will be a part of "Microsoft Office 12", a new version of the
Microsoft Office suite.
In "Excel 12", the maximum number of rows handled will be increased
from the current 65,536 to 1,048,576 (1500% more rows than in Excel
2003!) , and the number of columns will increase from 256 to
16,384. This means that the label of the rightmost column is "XFD"
instead of the current "IV". At present, you need Microsoft Office
Access to handle such large data, but you will be able to handle them
in the new Excel, as long as the number of rows is around 1 million or
less.
Other limits that will be expanded are:
- Total amount of PC memory that Excel can use
1GB -> Maximum allowed by Windows
- Number of sorting levels on a range or table
3 -> 64
- Number of conditional format conditions on a cell
3 conditions -> Limited by available memory
- The number of levels of nesting that Excel allows in formulas
7 -> 64
...etc.
New features are as follows;
- "Save as" function in PDF format.
- Sorting function not only by character or number, but also by
cell color.
...etc.
As you are aware, this is a major change in Excel's history! This
major change in the product might have been driven by threat of the
other open source software, such as OpenOffice. Anyway, I hope "Excel
12" will become more useful one.
The release timing of Microsoft Office 12 has not yet been announced.
But it is said that it will be ready in early 2006 according to
sources.
For more detail, click Microsoft developer's blog.

9 [Tech Info] Virtual Machine Makes Your Computer More Efficient
----------------------------------------------------------------------
A VM (Virtual Machine) is a computer which is defined in software. In
other words, VM simulates a computer. With VM, you can run two or more
operating systems on single computer at the same time. For example,
you can use Linux and Windows on single computer at the same time with
VM.
For servers or system administrators, VM can make the best use of
computer resources and save energy and space, because two or more VM
is running on a single computer. Adding that, with each VM which
serves for a specific service like DNS or WWW, it can make each
service more secure.
For users and developers, VM makes each PC more useful, because it
acts as many computers at low cost.
There are some VM software: Xen or OpenVZ as open source software; and
VMware, Virtual PC or Virtuozzo as commercial software.
This time, I would like to introduce VMware.
Originally, every VMware product was commercial software. Now, you can
use some of VMware products without fee: VMware player and VMware
Server.
With VMware player, you can execute ready-made VM and you can download
disk images of VM via the Internet.
With VMware server, you can try and evaluate most features of
VMware. But you can not use advanced features like dynamic load
balancing.
Because I use some hardware which has drivers for Windows only and I
need MS Office sometimes, I use Windows XP. But I need software for
UNIX, too. So I try VMware player and a disk image for OpenBSD which
is one of free software operating systems, and connect to VM for
OpenBSD via virtual network. In other words, I can use Windows and
OpenBSD on single computer at the same time. It makes me happy!
Of course, you can use VM for Linux or Windows.
Have a try!

10 [Tech Info] Ajax: A Boost to Web Technology
----------------------------------------------------------------------
As you may know, Macromedia Flash(TM) is commonly used to create
moving design elements on a web page. Well then, have you ever heard
of "Ajax"? Ajax (pronounced as "A-JAX") is an abbreviated expression
of "Asynchronous JavaScript And XML."
Ajax is not something you can download or buy. It is just a new
approach of building web applications. Using existing technologies
such as HTML, JavaScript, DOM, and XML, you can build very interactive
web applications without using Flash.
You may unconsciously have experienced Ajax when using Google Map,
Google Suggest, and so forth. Now check up Google Maps. Use zoom bar
to zoom in and zoom out. Use your cursor to grab the map and scroll
around. Every motion happens almost immediately without waiting for
pages to reload. In other words, the server asynchronously do
something without stalling a user's interaction with the application.
Ajax in not anti-Flash. We should use the right technology (Ajax,
Flash, etc.) in the right place.
Anyway, Ajax is an important development for Web applications, and its
importance is going to grow day by day. With Ajax, Flash, and the
other technologies, the Web is closer than ever to becoming a viable
default platform for application development.
You can see more on the web page of Mr. Jesse James Garrett, who is
the godparent of Ajax.

1 [Tech Info] ISO/IEC 27001:2005(ISMS Standard) Has Just Been Published
----------------------------------------------------------------------
ISO/IEC 27001:2005 has just been published on Oct. 15, 2005. It
replaces BS 7799-2:2002 (UK Standard). ISO/IEC 27001:2005 is a
management standard, which explains how to build, maintain and improve
an Information Security Management System (ISMS). It is based on risk
assessment and Plan-Do-Check-Act (PDCA) model. The standard provides a
specification for ISMS and the foundation for third party audit and
certification. It is harmonized to work with other management system
standards such as ISO 9001 and 14001.
"'The publication of ISO/IEC 27001:2005 is a big event in the
world of information security and the standard has been eagerly
awaited,' said Ted Humphreys, Convener of the working group
responsible for managing the development of the standard. 'It is a
standard that all security-conscious organizations should look to
implement.'"
http://www.iso.org/iso/en/commcentre/pressreleases/2005/Ref976.html
In addition to the development of ISO/IEC 27001, ISO/IEC JTC1 SC27 is
working on several other standards that will all be included in the
27000 series of standards - in analogy to the management system
standards, such as ISO 9001 and 14001.
The standards in the 27000 series are:
- ISO/IEC 27000: Information Security Management System Fundamentals
and Vocabulary (under development)
- ISO/IEC 27001: Information Security Management System - Requirements
(published)
- ISO/IEC 27003: Information Security Management System Implementation
Guidance (under development)
- ISO/IEC 27004: Information Security Management Measurement (under
development)
- ISO/IEC 27005: Information Security Risk Management (under development)
The integration of ISO/IEC 17799:2005 into the 27000 series will be
discussed and decided upon in spring 2007; a forward in ISO/IEC
17799:2005 is explaining this situation, and if ISO/IEC 17799:2005 is
integrated into 27000 series, it will obtain the number ISO/IEC 27002.
There is ISMS Conformity Assessment Scheme based on BS 7799-2:2002 in
Japan. Security Course participants studied details in "Making ISMS",
and all participants studied a little in "Security Basics". This
scheme will be revised in 2006, based on ISO/IEC 27001:2005.
----------------------------------------------------------------------
2 [Tech Info] PMP(R) Credential Exam System Changes
----------------------------------------------------------------------
On September 30, 2005, Project Management Institute (PMI(R))
officially revised Project Management Professional (PMP(R)) credential
examination. PMP is a credential awarded by PMI and currently the
number of PMP holders amounts to 50,000 all over the world.
The major changes in the exam are as follows:
- The new exam is based on "A Guide to the Project Management Body
of Knowledge (PMBOK(R)) Guide Third Edition", while the old exam
was based on "PMBOK Guide 2000 Edition".
- The passing score is 106 questions correct out of 175 scorable
questions (61 percent) , while it used to be 137 out of 200 (69
percent) in the old exam.
PMP exam can be taken in over 60 countries. Among the countries which
PMA Course participants belong to, Bulgaria, China, Indonesia,
Philippines, Romania, Turkey, and Uzbekistan have testing centers for
this certificate.

3 [Tech Info] GUI or CUI?
----------------------------------------------------------------------
There are two types of well-known user interfaces. One is "GUI
(Graphical User Interface)" and the other is "CUI (Character User
Interface)". GUI enables users to make operation more easily by using
graphics such as icons, buttons and pointing devices. On the other
hand, CUI prepares character-based interface such as terminal screens
and users input from keyboards.
Nowadays it seems that GUI has become mainstream not only for Windows
users, but also for UNIX/Linux users. Users do not have to memorize
and type the commands. It is good for beginners because anybody can
intuitively make operation with mouse click and visual guidance.
A young application specialist Y-san, who is a typical GUI user, says,
"I hate command. I hate terminal screen. I hate keyboard typing. Why
should we do such old aged operation in the era of GUI? We have many
useful tools and can make applications by drag and drop. It's enough!"
However, there remain persons who still love commands. Most of them
are very skillful developers, but they usually shut their heart to the
GUI world. A genius engineer O-san, who is an extreme command lover,
says, "If you like GUI, it's OK. Whatever you want. I do not want to
waste my time caring amateurs like you."
Why do they adhere to commands and never change their way? The answer
is easy. GUI is efficient only for the easy work, but for the complex
work, CUI has the great advantage. For example, if you want to put
extension ".oic" to all the files in your PC whose names include
"okinawa" and are updated in half a year, using command is far simpler
than using GUI.
K-san, the command analyst says, "Commands are represented by pure
text format so you can grasp all the system configuration as a
string. It means you can make the perfect reconfiguration of your
settings. Being represented by text format enables you to do iterative
operations using such technique like copy-and-paste, and/or
functioning."
If you are a typical GUI lover, try to use command sometimes. It will
make your work easier and more comfortable!
----------------------------------------------------------------------
4 [Tech Info] Skype Technology
----------------------------------------------------------------------
Skype, the Internet telephone software released two years ago, now has
over 60 million users in the world.
The reason of its popularity is the voice communication quality, which
is the same level as ordinary telephone. Therefore, users do not feel
stressed while talking. Another reason is that this service is free of
charge if used in PC-to-PC communication. You have to pay if you call
from Skype to ordinary telephone, however, the communication charge is
far less than that of ordinary telephone.
The inexpensiveness of this service comes from the low cost of the
service provider's facility. Normally, telephone service is provided
by expensive circuit switches owned by telephone companies. However,
Skype owns only the servers to manage their user accounts and
authenticate them. The other functions such as controlling calls are
allocated to users' computers dispersedly using P2P (peer to peer)
technology.
So far, this software is mainly for personal use, however, gradually
it has gained popularity among the companies that seek for lower
communication costs. Also it may become a key-application to integrate
telephone network into LAN.
The latest version of Skype supports video chat, which can be applied
to video conferences in companies. If you are interested in Skype,
please try to access the site below.
