While auditing a web service, you discover that a form field accepts special characters and sends them directly to a script for processing. Which measure best prevents malicious commands from being executed?
Set minimal privileges for the application account executing the script
Check all input fields with client-side filters
Review logs regularly and produce frequent threat reports
Use parameterized statements and disciplined data handling methods
Using parameterized calls and strict data handling keeps program instructions separate from the data that users supply. This reduces the chance of untrusted input triggering harmful commands. Generic client-side checks can be bypassed with manipulative techniques. Limiting access rights may slow an attacker but does not stop command-based exploits. Simple threat summaries do not fix major flaws, as unvalidated data can still lead to unauthorized commands.
