Hacker and Cracker

May 21st, 2008 at 16:57 · Filed Under Blogging, Call Me a Geek, Computing, Hacking, Security · 8 Comments 

I received an email from my sister, M. In her email, she pointed out I should not label myself as “hacker”. Well, I could not agree to her opinion so I decided to write this post entry to clear the name for all hackers.

Many people have watched too much Hollywood movies and have developed a perception that hackers are bad guys. They do not understand, nor can distinguish the difference between Hacker and Cracker.

Very well, Hacker and Cracker are like Good Sorcerer and Bad Sorcerer. Hackers are generally referring to a group of programmers or software engineers who dwell into codes of a computer system to find faults or loop holes so that the functionality, usually, security of the computer system can be improved. Hackers are also contributing to many open source device drivers to be used in open source software such as Linux. They study how a device communicates with a computer system without any documentation from the manufacturer (sometimes, some device manufacturers are reluctant to release technical information fearing their competitors may steal their secrets) and write codes to allow the device to communicate with the operating system.

Some hackers visit websites to look for security loop holes and put a file there to indicate their successful hack. Usually, they cause no disruption or damage but to alert system administrator of such security vulnerabilities. One of my website was hacked by hacker from Turkey last week. No damage or disruption caused but simply alerted me of security vulnerability. I quickly corrected the security flaw.

Hackers also study computer codes (binary or source) to learn about a computer software system so to rebuild another similar computer software system for the interest of know-how or to improve the software system. Instead of hacking, reverse engineering best described this type of activity.

Crackers, on the other hand, have the intention to harm or steal. They look for security vulnerabilities to get access into your computer system to cause disruption or steal your information for illicit purposes. Their ultimate goal is to cause damage or to gain something from you to be used for illicit activities, such as stealing your financial accounts or credit cards data for their financial gain.

There are many hacker organizations, for instance, BlackHat. It holds many international technical conferences and training around the world to improve information security.

Laypersons who do not understand the meaning of hacker generally think hacker is a bad guy. Being a hacker myself (sometimes), I just want to clear the name for hackers. And to show the good nature of a hacker, please read here and here.

Is your connection secured?

January 19th, 2008 at 10:33 · Filed Under Business, Call Me a Geek, Computing, Marketing, Security · Comment 

Internet has become a common tool to connect your mobile computer back to the computers in your office while you are on the go. When you are out there negotiating business with your client, you need to extract a file from your computer in your office but you are hundred or maybe thousands miles away, how can you retrieve your file?

The answer is by using FTP or File Transfer Protocol. You can make connection from your mobile computer to your office computer via an Internet connection. It is very convenient to use. But there is a security concern. All communications between your mobile and office computers can be read like an open book by anyone lurking in the Internet. You need a secured way to transfer your sensitive business data.

Pragma Systems SFTP client provides you a secured FTP connection by encrypting all data before they leave your computers. You can be rest assured of the confidentiality of your data during transmission. Don’t leave your office without it. You never know who is watching.

Product Seminars

January 15th, 2008 at 23:55 · Filed Under Business, Call Me a Geek, Computing, Conferences, Security, Social, Technology · Comment 

This morning I attended the Panasonic IP Camera Seminar at Panasonic Malaysia in Shah Alam. The drive was smooth but I was lost in Shah Alam trying to locate the place. I did not bring along my GPS but I managed to get to USJ11 where I was a little more familiar with. I took the long way by getting to the Federal Highway, paid the toll and found Panasonic Malaysia at last.

The seminar was organized by Panasonic and its distributor. Not so much of interesting talk. Organization was a little messy but overall good. Speakers were not very well trained and lack of exposure. The entire presentation was not too bad at all and it wasn’t boring as there were some people asking interesting questions. Most important of all was that I managed to establish contacts with Panasonic Malaysia.

Panasonic treated its guest very well with a nice buffet lunch. I took the lunch, washed down with dessert and drinks. Talked to my vendor and to establish closer relationship.

Then I had to rush to Hilton PJ to attend another IP camera event. It was a dealers gathering organized by Axis Communication and one of its distributor in Malaysia. The event was organized in Uncle’s Chili, a restaurant pub. Nice setup and cozy environment. The presentation was presented by Axis Singapore. The presentation was absolutely good and informative. Axis is a Swedish company and its IP cameras are world number 1.

Axis presentation had been very entertaining and educating at the same time. The presenter, Nafis Jasmani, had done a great job.

Axis and its distributor treated their guests very well too. Excellent and delicious food. I had a great “meal” with a beer together with some people I met there. Dessert was great too! The only thing I disliked was that people began to puff cigarette after food and beer. The smoke immediately destroyed the cozy environment and the nice cool air.

I spoke to Nafis before I left. We talked about Axis Developer Program and some technical details. As I understood from him, there are 4 developers in Malaysia developing some vertical Axis solutions. Quite an interesting fact.
