Database has always been the target of hackers because it contains all kinds of valuable and sensitive information, such as financial or intellectual property information, corporate data, personal user data, and so on. Hackers try to make a profit by destroying servers and databases, so database security testing is essential.

Hacker attacks on companies abound, and data breaches have occurred in Equifax,Facebook, Yahoo, Apple, Gmail,Slack and eBay in the past few years. This situation also leads to the need for network security software and web application testing. By adopting these measures, hackers will be denied access to available records and documents in online databases. In addition, strict compliance with GDPR helps to strengthen the protection of user data.

So what are the common loopholes in the database driver system? We summarize the ten common loopholes and the skills to eliminate them.

No security testing before deployment

One of the most common reasons for database attacks is negligence during the deployment phase of the development process. Although enterprises may have conducted functional tests to ensure high performance, this type of testing cannot show whether the database is performing operations that should not be performed. Therefore, it is important to use different types of tests to test site security before full deployment.

Poor encryption is inextricably linked to data leakage.

Many people will regard the database as a back-end part, so they are more concerned about the threat of Internet transmission, but they all ignore that the database also has network interfaces, and if the software security is poor, hackers can also easily track these interfaces. To avoid this, it is important to use TLS or SSL encrypted communication platforms.

Weak network security software = broken database

In the Equifax data leak, the company admitted that 147 million consumers' data had been compromised, with serious consequences. This case proves the importance of network security software in protecting databases. However, most enterprises are unwilling to conduct user data security testing or even provide regular patches for the system due to lack of resources or time, which can easily lead to data leakage.

The database was stolen

There are generally two kinds of threats in databases: external threats and internal threats. In some cases, internal threats are even more serious than external threats, because no matter what kind of security software the company uses, employee loyalty is not guaranteed. Anyone with access to sensitive data has the opportunity to steal it and sell it to a third-party organization for a profit. However, there is one way to eliminate risks: encrypting database files, imposing strict security standards, fining for violations, using cyber security software, and constantly raising team awareness through company meetings and personal consultations.

The defect in the function has become a database security problem.

Hackers can take advantage of the functional defects of the database to attack by cracking legitimate credentials and forcing the system to run arbitrary code. Although this sounds a little complicated, it is based on inherent flaws in the functionality, so you can protect the database from third-party access through security testing. In addition, the simpler the functional structure, the more opportunities there are to ensure that each database function is well protected.

Weak and complex database infrastructure

Hackers usually do not control the entire database at once, they take advantage of the special weaknesses in the infrastructure and use them to their strengths. Security software cannot completely protect the system from such operations. Even if you want to avoid functional defects, don't make the entire database infrastructure too complex. When it is complex, you may forget or neglect to check and fix its weaknesses. Therefore, it is important that each department maintain the same amount of control and isolate the system to distract the focus and reduce possible risks.

Unlimited administrative access = poor data protection

There should be a clear division of labor between administrators and users to ensure that the team has restricted access, so that if users try to steal any data, they will encounter more difficulties because they are not involved in the process of database management. If you can also limit the number of user accounts, so much the better, because hackers will also encounter more problems in gaining control of the database. This usually happens in the financial industry, where they are not only concerned about who has access to sensitive data, but also perform banking software testing before release.

Test the security of the website to avoid SQL injection

Because of the injection attack application, the database administrator is forced to clear malicious code and variables inserted into the string. Web application security testing and firewall implementation are the best options for protecting Web-oriented databases. However, this is a big problem for the online business, but not a challenge for the mobile business, and it is a big advantage for applications that only have a mobile version.

Insufficient key management

It is important to encrypt sensitive data, but it is also important to pay attention to who can access the key. Because keys are usually stored on hard drives, this is obviously an easy target for those who want to steal them.

Irregularities in database

Database vulnerabilities can be caused by a variety of reasons because of the need to test the security of the website and protect the data on a regular basis. If you find any differences, be sure to fix them as soon as possible. Enterprise developers should be aware of any threats that may affect the database.

Although enterprises may be aware of the need for security testing, there are still many enterprises that cannot implement them because fatal errors usually occur during the development phase, or during application integration, patching and updating the database.
