Reputation-Based Security

A method that evaluates the trustworthiness of entities (such as websites or users) based on reputation scores.

Understanding:

Reputation-based security uses threat intelligence and global reputation databases to classify files, URLs, IPs, and domains as trusted, suspicious, or malicious based on their behavior history.

Common Applications and Use Cases:

Malware & Phishing Protection – Blocks known malicious websites and files.
Spam & Email Filtering – Identifies phishing links based on reputation scores.
Zero-Day Threat Mitigation – Uses heuristics and reputation data to block new threats.

Best Practices and Security Considerations:

Integrate Reputation-Based Filtering – Enhances SIEM, IDS, and antivirus detection.
Leverage Global Threat Intelligence Feeds – Continuously update risk classifications.
Monitor False Positives – Ensures legitimate sites and services aren’t mistakenly blocked.
