How to Improve Database Security?
The modern businesses are moving forward with the cloud computing technology and each and every data is stored on a cloud. Even though these businesses are handling sensitive and valuable data with the cloud technology, but they are still suffering from the data hackers and breaches. As data is the valuable asset, database security has become one of the most major problems for any organization. So it’s important to improve database security framework more than ever. Database security may be complicated task, but there are many simple things that you can do to make your online work safer.
There are few considerations that should be followed in order to improve database security.
Understand Where Your Data Reside
If you don’t know where your data is exactly residing, then it will be crucial to have control on it in an effective manner. As per the IOUG survey, more than 70% of organizations handle sensitive data. These organizations must set up some precautions to handle sensitive data so that it should be secured from data breaches/ hackers. The database administrators should try to examine database frequently and they should check how data can be leaked or accessed in unauthorized manner.
Login Credentials Are Important
Login credentials have a major impact on your security. Surprisingly, still there are many people who use their personal details as their password. This is the easy way for hackers to hack your system when they try manually. So having a secure password that combines all cases and punctuations for database access can keep your data safer. The database administrators should change passwords on a revolving basis. If a password is not changed for more than 90 days then make sure to lock that account so that there will be no possible way for hackers to hack your sensitive data.
Segment Your Database
Segment your database to make sure that your data should not be mixed up with the other irrelevant data. In order to improve the efficiency of data, various roles can be created within the database. Manage your database by creating login credentials for users, super users, administrators and for super administrators. Users can only access for the data, not modify beyond what they’ve put in and super users can alter and modify the data, but they don’t have access to change login credentials. Finally database administrators, they can alter the structure of database and they can also have access to sensitive information. This hierarchy will secure your database and provides only basic information for the new users.
Encrypt Your Database
Encrypting data is as important as setting strong passwords. Encryption means converting whole data into letters and irrelevant numbers with no tangible meaning. When you access for the data only database program can easily convert your database to readable format by accessing the user password. For example, In 2012 Yahoo company was hacked and exposed more than 400,000 people password in plain text on web. This caused many people to change their login credentials and even company faced huge loss in that year. So make sure that your database is encrypted with updated encryption software.
Monitor Your Database frequently
One of the best ways to prevent your database from hackers is to check database very frequently. Monitoring logins and behavior of database users can help you to keep track of your data. Also checking the unfamiliar IP addresses can avoid the hackers. For example, automatically you will get a call/message from your banker when you did any transaction from your bank account. This procedure is called as red flag security, and the same procedure should be followed in your organization.
