Websites are often subject to attacks, especially SQL injection. SQL injection stands for “Structured Query Language Injection” and is particularly dangerous as it targets widely used database languages and is carried out by hackers.
Attackers use security vulnerabilities caused by programming errors to inject malicious code and manipulate databases. This gives the criminals access to valuable data records and enables them to carry out unwanted activities. By deliberately manipulating scripts and programs, attackers can integrate unwanted commands into web applications. Successful SQL injection attacks can have serious consequences, including compromised data integrity, attacker access to the system and loss of privacy. An injection attack manifests itself through redirected advertising, data leakage, manipulation of user accounts, error messages or the receipt of a large number of requests. The cost is not only financial, but can also damage customer trust and reputation. It is therefore crucial to take appropriate security measures.
To protect against SQL injections, clean source code, validation of input data and the use of web application firewalls are advisable. Automated scanning tools and penetration tests during development help to identify vulnerabilities.
