The below article explains some database tips in order to prevent the malicious attacks on Database
Database security is the serious concern of industry analysts and professionals. Now a days every web application has back end with different databases. Protecting your database is important for making your data more secure. Here are some tips to protect your database to make your data secure
Training on Security
Thinking about the security is more concerned about so many safety reasons. You have to continuously access the user actions in terms of their security. Usually developers do this very rarely often once for 60 days. Due to this developers and testers think in the same way as the end user does. Train the entire team to think in terms of security system. Lack of trained persons and safety rules in designing the databases tends to malicious attacks in the databases. Ensure that every team member is trained in terms of designing security terms. Lack of training leads to make a path for hackers
Privileges and Rights on Database
Every web application is developed with minimum set of privileges and depending uppon their privileges the user will have restrictions on some of the pages. We have to review the user permissions atleast once a week, in order to ensufre the security. Most of the companies give the access to their databases to contracters, temporary employees. Once they left the company they will forget about the restriction or removal of that access. This may lead to unpredictable situations As a result, not only to restrict user access to the database, but there is a need for regular review of access rights and their refinement. Therefore, in each case very carefully think over what rights should be granted to the user or application.
Minimize the space attack
It is more difficult to secure a large house with more windows than a small house with several windows. Similar is the case with databases. What they are more complex, the greater the perimeter for the attack. Try to limit the perimeter, removing those components that are not used.
Manage Passwords
One of the main and most simple goals for hacker attacks – the user accounts from the default or weak passwords. The list of passwords assigned by default, can be found on the Internet, and there are many tools that help hackers to crack these passwords, for example, using the so-called rainbow tables (rainbow table) and to conduct various kinds of attacks. Use these same tools to identify weaknesses and “credit-default passwords in the database.
Encrypting your Database
Encryption – this is usually the first thing that comes to mind when thinking about database security, and it certainly makes sense to recommend to protect sensitive information. However, this method of protection is not cheap, and in itself it is not easy to use and manage. Encrypt only the critical data, for the protection of which is a must. Attentive to the management of encryption keys / decryption and change them regularly. It is important to combine encryption with other tools and procedures, such as activity monitoring, auditing, periodic vulnerability assessment and authentication of users.
Approach to security must be comprehensive
Many companies provide funds and resources to ensure the security of databases, but ignore that in the development and testing environment for these bases, as well as to create preliminary demos. Since the demo code has since been frequently transferred into the final version of the program, it should be as safe as the main code. In addition, real data is often used in satellite environments, without disguise. This raises serious security threat. It is strongly recommended to treat the subsidiary instruments as well as to major.
Update your software using patches
Most of the companies use different softwares within the company. The software providers will release special patches. We need to make that patch attachable to the currently using software. Much has been said and written about how vendors DMBS cope with vulnerability and how quickly they close them with special patches. However, the number of detectable “holes” in recent years only grows. Although vendors are redoubling their efforts, redouble efforts and hackers. In addition, the distribution of software patches usually takes several months. And a few months, customers install them in their programs, because time is needed to test the updates. Many customers ignore patches, and then their databases remain vulnerable to various attacks. Installing the patch should be immediately upon receipt
