Introduction:
The recent Initial Planning Conference for Locked Shields 2026 has set the stage for the world’s most complex cyber defence exercise. This massive collaboration between 35 industry partners and national teams represents the cutting edge of cyber warfare training, simulating large-scale, real-time attacks on national IT infrastructure. Understanding the core concepts and technical maneuvers practiced in such exercises provides invaluable insight for cybersecurity professionals worldwide.
Learning Objectives:
- Understand the core infrastructure components and attack vectors simulated in major cyber exercises
- Master key defensive commands and techniques used to secure critical systems
- Develop incident response procedures for enterprise-level cyber attacks
You Should Know:
1. Network Infrastructure Hardening
`iptables -A INPUT -p tcp –dport 22 -s 192.168.1.0/24 -j ACCEPT`
`iptables -A INPUT -p tcp –dport 22 -j DROP`
Step-by-step guide: These iptables commands restrict SSH access to specific subnets while dropping all other connection attempts. First command allows SSH from 192.168.1.0/24 network, second command blocks all other SSH attempts. Essential for limiting attack surface in critical infrastructure.
2. Windows Server Hardening
`Get-Service | Where-Object {$_.StartType -eq “Auto” -and $_.Status -eq “Running”} | Select-Object Name, DisplayName`
`Set-Service -Name “ServiceName” -StartupType Disabled`
Step-by-step guide: The first PowerShell command identifies all automatically starting services currently running. The second command disables unnecessary services that could provide attack vectors. Critical for reducing potential entry points in Windows-based infrastructure.
3. Log Analysis and Threat Detection
`grep “Failed password” /var/log/auth.log | awk ‘{print $11}’ | sort | uniq -c | sort -nr`
`journalctl -u ssh.service –since “today” | grep “Failed”`
Step-by-step guide: These commands analyze authentication logs for brute force attempts. First command shows failed login attempts by IP address with count, second command checks today’s SSH failure logs. Vital for identifying ongoing attacks during exercise scenarios.
4. Cloud Security Configuration
`aws iam get-account-authorization-details –query “Policies[?PolicyName==’AdministratorAccess’]”`
`gcloud projects get-iam-policy PROJECT_ID –format=json | grep -A5 -B5 “user:”`
Step-by-step guide: These cloud commands audit administrative access permissions in AWS and GCP environments. First checks for AdministratorAccess policies, second examines IAM policies for user permissions. Crucial for maintaining least privilege in cloud infrastructure.
5. API Security Testing
`nmap -p 443 –script http-security-headers `
`curl -H “Authorization: Bearer token” -X GET https://api.example.com/data | jq .`
Step-by-step guide: First command scans for missing security headers in web services, second tests API authentication and response parsing. Essential for identifying vulnerable endpoints in web applications.
6. Incident Response Containment
`netstat -tulpn | grep ESTABLISHED`
`ss -s | grep -E “(LISTEN|ESTAB)”`
`tcpdump -i eth0 -w capture.pcap host 192.168.1.5`
Step-by-step guide: These commands monitor active connections and capture network traffic during security incidents. First shows established connections, second provides socket statistics, third captures packets for analysis. Critical for containing breaches during attack scenarios.
7. Vulnerability Assessment
`nmap -sV –script vuln `
`nessuscmd –target –policy “Basic Network Scan”`
`openvas-cli –target –format=html > scan_report.html`
Step-by-step guide: These commands perform comprehensive vulnerability scanning using Nmap, Nessus, and OpenVAS. First uses Nmap’s vulnerability scripts, second runs Nessus basic scan, third executes OpenVAS assessment. Essential for identifying weaknesses before attackers do.
What Undercode Say:
- The scale of Locked Shields 2026 (300+ participants, 35 industry partners) indicates increasingly sophisticated attack simulations moving toward hybrid warfare scenarios
- Public-private partnership models demonstrated in these exercises represent the future of collective cyber defence
- The technical complexity requires defenders to master both traditional infrastructure security and emerging cloud/API vulnerabilities
The Locked Shields exercise framework provides unprecedented insight into nation-state level attack methodologies and defence strategies. The integration of industry partners with military and civilian planners creates a realistic training environment that anticipates emerging hybrid threats. This collaboration model significantly advances global cyber readiness by fostering information sharing and standardizing defence protocols across sectors. The technical requirements demonstrated—from cloud security to incident response—establish new benchmarks for enterprise cybersecurity preparedness.
Prediction:
The Locked Shields 2026 exercise will accelerate the adoption of military-grade security practices in private sector organizations, particularly in critical infrastructure. The techniques and attack vectors simulated will likely emerge in real-world campaigns within 18-24 months, making these exercises crucial early warning systems. The increased focus on API security and cloud infrastructure in recent exercises predicts these areas will become primary attack surfaces in future sophisticated campaigns. The collaboration model pioneered by NATO CCDCOE will likely become the standard for public-private cybersecurity cooperation globally.
