# Actionable Guidance for AlgoSec # Generated: 2026-04-03 21:22:51 # Step 1: Navigate to AlgoSec Firewall Analyzer (AFA) → Risks → Risky Rules # Purpose: Identify overly permissive rules (e.g., 'Any' source/destination/service) that could allow lateral movement from compromised development environments or vulnerable applications like TrueConf. # Expected: A prioritized list of high-risk firewall rules across the network fabric that violate least-privilege principles and require immediate tightening. # Step 2: Navigate to AlgoSec Firewall Analyzer (AFA) → Network Map → Traffic Simulation Query # Purpose: Simulate lateral movement paths by querying traffic from the vulnerable application segment (Source) to critical internal networks (Destination) across all ports. # Expected: A visual path analysis showing exactly which firewalls, routers, and specific rules currently permit unauthorized traffic between the compromised segment and critical assets. # Step 3: Navigate to AlgoSec FireFlow → New Request → Traffic Change Request # Purpose: Initiate a zero-trust policy update to drop unauthorized traffic and enforce strict microsegmentation around the affected application servers. # Expected: An automated, risk-analyzed change request that designs and pushes restrictive firewall rules to the relevant enforcement points without breaking legitimate application traffic (AppViz integration). # Verification Steps: # - Generate a new AFA Device Report for the firewalls segmenting the vulnerable environment. # Expected: The previously identified risky rules are marked as removed or modified, and the overall device risk score is measurably reduced. # - Re-run the AFA Traffic Simulation Query from the vulnerable segment to critical internal zones. # Expected: The query result explicitly shows a 'Blocked' status, confirming that lateral movement paths have been successfully severed.
