Slide from my recent presentation at MyGOSSCON 2010

A big thank you to those who attended my presentation. Big applause to the organizer.

WordPress has a new release to fix the danger of SQL Column Truncation. It is recommended if you are allow open registration on your blog. This problem is not critical but it is annoying.

Upgrade to the latest version is highly recommended.

Many distributions of Linux have an option to install MySQL. In this case, or even if you compile MySQL, the default password is blank.

Make sure that you set password for the root user. This is the command:

mysql -u root mysql
SET PASSWORD FOR 'root'@'localhost' = PASSWORD('s3cr3tp4s5w0rd');

Yesteday, I presented a full-day tutorial on SQL Injection & Session Hijacking In PHP Programming which seems to have been well received by those who attended. And today, I would like to present to you a new Inspekt Build available to be downloaded at Google Code.

What is Inspekt?

Inspekt acts as a sort of ‘firewall’ API between user input and the rest of the application. It takes PHP superglobal arrays, encapsulates their data in an “cage” object, and destroys the original superglobal. Data can then be retrieved from the input data object using a variety of accessor methods that apply filtering, or the data can be checked against validation methods. Raw data can only be accessed via a ‘getRaw()’ method, forcing the developer to show clear intent.

It supports PHP4 & PHP5. More info at http://code.google.com/p/inspekt/

- Sample Basic Usage

Yes. It’s True. Public Wifi can be dangerous if you don’t use it securely. Unsecured connections make it possible for anonymous attacker track your surfing. If you want to use Gmail in a public Wifi :

If you go to the default google mail page – http://gmail.google.com you will be redirected to a secure site to log in, but will then be redirected to an unencrypted site for emailing. This makes you a potential risk for anyone who might be eavesdropping on the network.

Simply type an ’s’ at the http ID like this: https://gmail.google.com (and bookmark the URL) and you will be encrypted with SSL throughout your entire email session.

Ok Friends! Be safe.
