Intrusion Detection Software FAQs
How is an IDS different from a firewall?
An IDS detects and alerts on suspicious activity, while a firewall blocks or allows network traffic based on rules. IDS focuses on detection, not prevention.
Can IDS stop attacks automatically?
Not on its own. IDS detects threats, while intrusion prevention systems (IPS) block them. Using both provides stronger protection.
How often should IDS be updated?
Regularly. Frequent updates ensure your system recognizes the latest threats and vulnerabilities.
What are the main challenges of using IDS?
False positives, complex configurations, and high resource use can occur if not tuned properly. Regular review and maintenance help minimize these issues.
Do small businesses need IDS?
Yes. Even small networks face security risks. Lightweight or cloud-based IDS options offer affordable, effective protection.
