Database Security Tips

When developing website or ecommerce solution, important aspect of the design is the database security. The database needs to be protected from any security loopholes. If you’re using MySQL, one way to protect your db is by using MySQL access privileges system. You create specific user type for different user activity.

For example, if you developing website where user can register and add content inside your website. You might have three type of users:

Public : general user who might just select and browse through your site.

Registered : User who can add content to your site.

Admin : User who manage your users and content. Ban the users and some other admin function.

Based on the user types , you create separate MySQL user accounts with the following permission.

Public : SELECT

Customer : SELECT, INSERT, UPDATE

Admin : SELECT, INSERT, UPDATE, DELETE

You could write your configuration file as follow:

DEFINE(‘DB_HOST’,’localhost’);

DEFINE(‘DB_NAME’,’databasename’);

If (isset($user) && ($user==’Admin’)) {

DEFINE(‘DB_USERNAME’,’usernameA’);

DEFINE(‘DB_PASSWORD’,’passwordA’);

} 

elseif (isset($user) && ($user==’Customer’)) {

DEFINE(‘DB_USERNAME’,’usernameB’);

DEFINE(‘DB_PASSWORD’,’passwordB’);

}

else {

DEFINE(‘DB_USERNAME’,’usernameC’);

DEFINE(‘DB_PASSWORD’,’passwordC’);

}

Keep the connection file outside of your web root, in a private folder. This prevents outsider’s access to site. If you don’t have a private folder, then protect the file by using .htaccess

Try not to provide the following permissions to users who connect from website. If you got hacked, you will give lots of fire power to the hacker to do the damage.

PROCESS, FILE, SHUTDOWN, DROP, CREATE and ALTER.

By limiting the users’ permission you can protect your site from any harm. Even if you site has been hacked, the damage could be limited.

Nuffnang Reports It's Site Has Been Hacked

The email is below. 

Dear Nuffnanger,

Hope this email finds you well! We'd like to ask if you could please spend a few minutes of your time on this very important community announcement.

Yesterday evening on Friday (22nd July), we discovered an illegal and unauthorised intrusion into our network, which was the latest in a series of hacking incidents by a group of individuals who also claim to have targeted Streamyx, CIMB, TV3 and the several other local websites previously. In our case, the hackers claimed to have downloaded a portion of our blogger account information and published the emails of some 30,000 Nuffnang accounts.

The breach has since been fixed, and we’d like to address a few key concerns that you may have.

1. Your password is safe.

As part of the existing security measures, all user passwords in our database have always been protected with one-way encryption. Nevertheless, we still encourage you to change your password (especially if you use the same password for other sites) as a precautionary measure in case the hackers are able to get past the encryption.

2. Blog earnings and payment records are not affected.

Current earnings and payment history for all users are safe and were not compromised in any way.

3. Loading of blogs serving Nuffnang ads is not affected.

At 1.00 am last night, our Tech team took down the website for maintenance and for a few hours, ads were not served. This morning though, everything is up and running again and back to normal. All blogs serving Nuffnang ads loaded as usual and were not affected by the breach.

This security lapse is an isolated incident, as the security of our sites has always been and always will be our utmost priority. It has however opened our eyes on some vulnerabilities we had on our website. In response to that, we will be taking measures to further heighten the security of the Nuffnang framework because from what we understand, that was after all the motivation of the hackers – not to cause any permanent damage, but to highlight vulnerabilities in a system.

To the Nuffnangers who made many attempts to alert us once word got out that the Nuffnang site was hacked, we cannot begin to thank you enough.

To the wonderful Nuffnang community, thank you for standing by us in this time of crisis. Your patience and support is something we are thankful for and will never take for granted. We apologize for any inconvenience caused, and for not being able to prevent this breach. We have put dedicated staff to work on this matter, therefore to address any concerns or questions you may have about this incident, please write in to us at security [at ] nuffnang [dot ] com

Thank you.

Sincerely,

The Nuffnang Team

Facebook Advertising Costs, Daily Budget & Pricing

Facebook is a good advertising platform for your business. You don’t need have a specific budget amount to start a campaign. I have started mycampaign for less than 10 USD.

There costs for Facebook advertising depends whether you select Pay for Impression (Cost Per Thousand Impression - CPM) orPay for Click (Cost per Click - CPC).

The minimum cost that the system allows you to set in the ad campaign is USD 0.02 for CPM and USD 0.01 forCPC. The system will suggest the bid amount, but you could set it lower. For my campaign, I put USD 0.02 the minimum amount for 1000 impressions and still manage to run my campaign as I want.

If you want to create awareness for your new portal, product or service but you don’t care whether the people actually click the advertisement than you should choose Pay per impression pricing for your campaign. Or else use CPC pricing for your campaign.

The minimum daily budget for CPC and CPM is USD 1.00 and Facebook advertising will not charge you more than the minimum budget you have set. In addition, your daily budget must be 2 times the CPC or CPM amount that you set. If you set 10 USD for the CPC, then your minimum daily budget must be set as 20 USD.

Facebook will charge your Paypal or credit card for the campaign on a specific billable date or earlier if you have stopped/completed your campaign.
