Pros and cons

While signature-based detection is swift and resource-efficient, its primary drawback is that it cannot identify new or modified attacks not yet cataloged.

Behavior-based detection

Behavior-based detection focuses on identifying anomalous activities rather than known signatures. This technique analyzes user behavior and form interactions, flagging deviations from typical patterns.

How it works

By establishing a baseline of normal user interactions, behavior-based systems can detect anomalies that may indicate malicious activity. For instance, a sudden influx of data submissions from a specific user could trigger alerts.

Use cases and effectiveness

Behavior-based detection is particularly effective in scenarios where attackers modify their tactics to bypass signature-based defenses, making it invaluable for ongoing protection.

Machine learning implementations

Machine learning has revolutionized the detection of malicious forms by allowing systems to learn from historical data and get smarter over time. Implementations can include various models tailored to capture the complexity of user interactions.
