injektiohyökkäyksinä

Injektiohyökkäys is a Finnish term that translates to "injection attack" in English. It refers to a type of cyberattack where malicious code is inserted into a computer system or application. This is typically achieved by sending untrusted data to an interpreter or application. The attacker exploits vulnerabilities in the software to execute arbitrary code, access sensitive data, or disrupt the normal functioning of the system.

A common example of an injection attack is SQL injection, where an attacker manipulates database queries by inserting malicious SQL statements. This can allow them to read, modify, or delete data from the database. Another well-known type is command injection, where an attacker injects operating system commands that are then executed by the vulnerable application. Cross-site scripting (XSS) is another form, where attackers inject client-side scripts into web pages viewed by other users.

The primary goal of an injektiohyökkäys is often to gain unauthorized access, steal information, or compromise the integrity of a system. Prevention methods include input validation and sanitization, using parameterized queries or prepared statements for database interactions, and employing Web Application Firewalls (WAFs). Developers must be vigilant in sanitizing all user-supplied input to prevent such attacks from succeeding.
