Security Intelligence

💡 HTTP Header Analysis for Threat Detection

Examining HTTP headers beyond User-Agent reveals attack tools and automated scripts. Missing standard headers, unusual ordering, non-standard values, and inconsistencies with claimed client identity all serve as reliable detection signals.

💡 Backup and Recovery Against Ransomware

Immutable, offline backups remain the most effective defense against ransomware. The 3-2-1 rule — three copies on two media types with one offsite — combined with regular recovery testing ensures business continuity after encryption attacks.
