Next-Generation Firewalls (NGFWs) are often underutilized, with most organizations leveraging only 30-40% of their capabilities. When properly configured using the MITRE ATT&CK framework, NGFWs can mitigate 118 different attack techniques across 12 critical tactics.

Key NGFW Protections Across MITRE ATT&CK Tactics

  1. Execution Phase – Blocks malicious code via IPS and application control.
  2. Persistence & Privilege Escalation – Detects abnormal traffic patterns indicating attacker persistence.
  3. Defense Evasion – Uncovers obfuscated/encrypted traffic via SSL Inspection.
  4. Discovery – Limits network reconnaissance via strict segmentation policies.
  5. Lateral Movement – Restricts attacker movement via zone-based controls.
  6. Collection – Identifies unusual data aggregation when integrated with SIEM.
  7. Command & Control (C2) – Disrupts C2 channels via Web/DNS Filtering.
  8. Exfiltration – Prevents data theft via deep packet inspection.

You Should Know: Practical NGFW Configurations

1. Enabling MITRE ATT&CK-Based IPS Rules

 Palo Alto: Enable Threat Prevention with MITRE Mappings 
set security profiles threat-prevention rule <rule-name> mitre-mapping <Tactic-ID>

FortiGate: Apply ATT&CK-based IPS signatures 
config ips sensor 
edit "MITRE_IPS" 
set comment "MITRE ATT&CK Mapped Signatures" 
config entries 
edit 1 
set rule <MITRE_Rule_ID> 
set action block 
next 
end

2. Implementing SSL Inspection

 Check SSL decryption policies (Palo Alto) 
show running security-policy rule "SSL-Decrypt"

FortiGate SSL Deep Inspection 
config firewall ssl-ssh-profile 
edit "Deep-Inspect" 
set supported-alpn http1-1 
set untrusted-caname "Block-Untrusted"

3. Network Segmentation (Zero Trust Approach)

 Linux: Isolate segments using iptables/nftables 
sudo nft add rule ip filter FORWARD iifname "eth1" oifname "eth2" ct state new block

Windows: Restrict lateral movement via Firewall 
New-NetFirewallRule -DisplayName "Block-Lateral" -Direction Inbound -Action Block -Protocol TCP -LocalPort 445,3389

4. Detecting C2 Traffic with DNS Filtering

 Block known malicious domains (Linux DNS Filtering) 
sudo iptables -A OUTPUT -p udp --dport 53 -m string --hex-string "|06|google|03|com" -j DROP

Windows: Log suspicious DNS queries 
Get-WinEvent -LogName "Microsoft-Windows-DNS-Client/Operational" | Where-Object {$_.Message -like "malicious.com"}

5. SIEM Integration for Behavioral Analysis

 Splunk query for NGFW logs (Exfiltration detection) 
index=firewall src_ip= dest_ip= bytes_out>1000000 | stats sum(bytes_out) by src_ip, dest_ip

ELK Stack (Detect abnormal data transfers) 
GET /firewall-/_search 
{ "query": { "range": { "bytes_sent": { "gte": "1000000" } } } }

What Undercode Say

NGFWs are not just perimeter tools—they are multi-layered defense systems when configured with MITRE ATT&CK. Key takeaways:
– Enable SSL Inspection to catch encrypted threats.
– Segment networks to limit lateral movement.
– Integrate with SIEM for real-time behavioral analysis.
– Use DNS/Web Filtering to disrupt C2 channels.

Expected Output:

  • A hardened NGFW blocking 90%+ of ATT&CK techniques.
  • Reduced attack surface via segmentation and Zero Trust.
  • Detect data exfiltration before it happens.

Prediction:

As attackers evolve, AI-driven NGFWs will auto-adapt rules using MITRE ATT&CK intelligence, reducing manual configuration gaps.
