Episode: Advanced Data Protection Strategies: Snapshots, Replication, Journaling, Encryption
In this episode of DeepDive, XatusBetaZx17 compares four pillars of modern data protection—point-in-time snapshots for fast rollback, replication (sync/async) for site resilience, journaling file systems for crash-consistent recovery, and encryption with sound key management. We’ll map these techniques to RPO/RTO targets and show how to combine them (e.g., snapshot schedules + off-site replication + journaled FS + encryption) to harden your environment against outages and ransomware.

Episode: Network Security Appliance Attributes and Behaviors
In this episode of DeepDive, XatusBetaZx17 explores how core security appliances actually work and where they shine—covering firewalls (packet-filtering, stateful inspection, and application-proxy behaviors), next-gen capabilities (app/user-aware policies, threat prevention), and IDS/IPS engines (signature vs. anomaly detection, inline vs. passive). We’ll also touch on logging/telemetry, high availability, and how these attributes fit into a layered, real-world security architecture—so you can choose the right device for the job and deploy it with confidence.
