  • Implement identity and access management (IAM) best practices, including passwordless and Zero Trust principles.
  • Deploy AI observability and governance frameworks to monitor and secure autonomous agents.
  • Develop a cyber resilience strategy that anticipates, withstands, and recovers from sophisticated breaches.

You Should Know:

  1. Hardening the Core: Linux and Windows Commands for Zero-Trust Defense

The foundation of cyber resilience begins with system hardening. Attackers increasingly exploit misconfigurations and weak credentials to gain initial access. The following commands establish a baseline security posture on both Linux and Windows environments.

Linux Hardening (Bash):

  • Firewall Configuration (iptables/nftables): Restrict inbound traffic to only necessary ports. 
    Flush existing rules and set default policies to DROP
sudo iptables -F
sudo iptables -P INPUT DROP
sudo iptables -P FORWARD DROP
sudo iptables -P OUTPUT ACCEPT
Allow established connections and loopback
sudo iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
sudo iptables -A INPUT -i lo -j ACCEPT
Allow SSH (port 22), HTTP (80), HTTPS (443) - customize as needed
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 443 -j ACCEPT
Save rules (Debian/Ubuntu)
sudo iptables-save > /etc/iptables/rules.v4

  • User and Permission Hardening: Disable root login via SSH and enforce key-based authentication.

    Edit /etc/ssh/sshd_config
sudo nano /etc/ssh/sshd_config
Set: PermitRootLogin no
Set: PasswordAuthentication no
Set: PubkeyAuthentication yes
Restart SSH service
sudo systemctl restart sshd

  • Auditing with auditd: Monitor critical system files for unauthorized changes.

    Install auditd
sudo apt-get install auditd -y
Watch /etc/passwd and /etc/shadow for writes
sudo auditctl -w /etc/passwd -p wa -k identity_changes
sudo auditctl -w /etc/shadow -p wa -k identity_changes
Review logs
sudo ausearch -k identity_changes

Windows Hardening (PowerShell):

  • Firewall Configuration: Block inbound traffic except for essential services.

    Set default inbound policy to Block
Set-1etFirewallProfile -Profile Domain,Public,Private -DefaultInboundAction Block
Allow RDP (port 3389) - customize as needed
New-1etFirewallRule -DisplayName "Allow RDP" -Direction Inbound -Protocol TCP -LocalPort 3389 -Action Allow
Enable logging for dropped packets
Set-1etFirewallProfile -Profile Domain,Public,Private -LogBlocked True

  • User Account Control and Privilege Management: Enforce UAC and restrict local admin rights.

    Enable UAC (requires reboot)
Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System" -1ame "EnableLUA" -Value 1
Disable Guest account
Disable-LocalUser -1ame "Guest"
List all local users with admin rights
Get-LocalGroupMember -Group "Administrators"

  • Sysmon for Advanced Logging: Deploy Sysmon to capture detailed process and network activity.

    Download Sysmon from Microsoft Sysinternals
Invoke-WebRequest -Uri "https://live.sysinternals.com/Sysmon64.exe" -OutFile "C:\Sysmon\Sysmon64.exe"
Install with default configuration
C:\Sysmon\Sysmon64.exe -accepteula -i
View Sysmon events in Event Viewer (Applications and Services Logs/Microsoft/Windows/Sysmon/Operational)

  1. Securing the Cloud: AWS and Azure CLI Hardening

With 71% of organizations using AI coding assistants that access cloud credentials, securing the cloud perimeter is paramount. Attackers can pivot from a developer workstation to production environments in minutes. Implement these controls to mitigate cloud exposure.

AWS CLI Hardening:

  • Enforce IAM Least Privilege: Create and attach policies that grant only necessary permissions. 
    Create a policy that denies all actions except S3 read on a specific bucket
aws iam create-policy --policy-1ame S3ReadOnlyPolicy --policy-document '{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::your-bucket-1ame/"
}
]
}'
Attach policy to a user or role
aws iam attach-user-policy --user-1ame YourUserName --policy-arn arn:aws:iam::your-account-id:policy/S3ReadOnlyPolicy

  • Enable CloudTrail and GuardDuty: Ensure comprehensive logging and threat detection.

    Enable CloudTrail in all regions
aws cloudtrail create-trail --1ame my-trail --s3-bucket-1ame my-cloudtrail-bucket --is-multi-region-trail
aws cloudtrail start-logging --1ame my-trail
Enable GuardDuty
aws guardduty create-detector --enable

Azure CLI Hardening:

  • Azure Policy for Compliance: Enforce tagging and resource constraints.

    Create a policy to require a specific tag on all resources
az policy definition create --1ame 'RequireTag' --rules '{
"if": {
"field": "tags['CostCenter']",
"exists": "false"
},
"then": {
"effect": "deny"
}
}'
Assign the policy to a subscription
az policy assignment create --1ame 'RequireTagAssignment' --policy 'RequireTag' --scope /subscriptions/your-subscription-id

  • Microsoft Defender for Cloud: Enable enhanced security features.

    Enable Defender for Cloud on a subscription
az security pricing create -1 VirtualMachines --tier 'Standard'
View security recommendations
az security task list

3. API Security and AI Observability

As AI agents communicate via APIs, securing these endpoints is critical. The OWASP API Security Top 10 provides a framework for identifying common vulnerabilities. Additionally, AI observability tools like Cribl’s new offering can monitor token consumption and sensitive data exposure.

  • API Gateway Configuration (NGINX Example): Implement rate limiting and IP whitelisting. 
    /etc/nginx/nginx.conf
http {
limit_req_zone $binary_remote_addr zone=api_limit:10m rate=10r/s;
server {
location /api/ {
limit_req zone=api_limit burst=20 nodelay;
allow 192.168.1.0/24;  Whitelist internal IPs
deny all;
proxy_pass http://backend_api;
}
}
}

  • AI Observability with Telemetry: Use tools like Cribl to inspect AI model usage.

    Example: Using Cribl to route AI telemetry data
Cribl Stream configuration (web UI or API)
Define a pipeline to filter and route AI-related logs to a secure SIEM
Monitor for anomalies in token usage or data exfiltration patterns

  1. Identity and Access Management (IAM): Passwordless and Zero Trust

Identity-based attacks now account for 75% of all breaches. Transitioning to a passwordless, Zero Trust architecture is no longer optional.

  • Implement Passwordless Authentication (Azure AD): 
    Enable FIDO2 security keys for Azure AD users
Via Azure Portal: Azure AD > Security > Authentication methods > Policies
Or use PowerShell
Connect-MgGraph -Scopes "Policy.ReadWrite.AuthenticationMethod"
Update-MgPolicyAuthenticationMethodPolicy -AuthenticationMethodConfigurations @(
@{
"@odata.type" = "microsoft.graph.fido2AuthenticationMethodConfiguration"
Id = "Fido2"
State = "enabled"
}
)

  • Continuous Access Evaluation (CAE): Enforce real-time policy evaluation.

    Azure AD Conditional Access policy for CAE
Require compliant devices and MFA for all cloud apps
New-MgIdentityConditionalAccessPolicy -DisplayName "Require Compliant Device and MFA" -State "enabled" -Conditions @{
Applications = @{
IncludeApplications = @("All")
}
Users = @{
IncludeUsers = @("All")
}
Devices = @{
IncludeDevices = @("All")
}
ClientAppTypes = @("browser", "mobileAppsAndDesktopClients")
} -GrantControls @{
Operator = "AND"
BuiltInControls = @("mfa", "compliantDevice")
}

5. Cyber Resilience: Anticipate, Withstand, Recover, Adapt

Gartner’s Cyber Resilience Framework emphasizes anticipating threats, withstanding attacks, recovering swiftly, and adapting continuously. CommVault’s integration of Google Threat Intelligence into recovery workflows exemplifies this, enabling clean recovery point identification.

  • Automated Backup Validation (Linux): 
    Example: Using rsync with checksums to validate backup integrity
rsync -av --checksum /source/ /backup/
Verify with diff
diff -r /source/ /backup/

  • Disaster Recovery Playbook (Windows PowerShell):

    Script to initiate failover to a secondary site
Requires Azure Site Recovery or similar configured
Import-Module Az.RecoveryServices
$vault = Get-AzRecoveryServicesVault -1ame "YourVaultName"
Set-AzRecoveryServicesVaultContext -Vault $vault
Start-AzRecoveryServicesAsrPlannedFailoverJob -ProtectionContainerMapping $mapping -Direction "PrimaryToRecovery"

6. Threat Hunting with AI Agents

AI agents are now capable of continuous threat hunting, reducing the mean time to detect (MTTD) and respond (MTTR). However, they must be governed to prevent risky behavior.

  • Deploying an AI Threat Hunter (Conceptual): 
    Example: Using a hypothetical AI agent CLI to initiate a hunt
ai-threat-hunter start --scope "all-endpoints" --query "suspicious process creation" --output "json"
Review findings
cat /var/log/ai-hunter/results.json | jq '.findings[] | select(.severity=="high")'

  • Govern AI Agent Activity:

    Monitor AI agent API calls using a proxy like mitmproxy
mitmdump -q -w ai_agent_traffic.log -s "filter_script.py" --mode transparent
filter_script.py can inspect and log requests for anomalies

What Undercode Say:

  • Key Takeaway 1: The attack surface has fundamentally expanded with the integration of AI agents into enterprise workflows; securing these agents requires a combination of traditional hardening, AI-specific governance, and continuous visibility.
  • Key Takeaway 2: Cyber resilience is not about preventing all attacks but about minimizing business disruption through rapid recovery and adaptation; organizations must invest in backup validation, threat intelligence integration, and automated response.

Analysis: The shift from AI-assisted tools to autonomous AI agents represents a paradigm shift in both offense and defense. Attackers can now chain exploits at machine speed, as demonstrated by Sysdig’s research showing an AI agent moving from a vulnerability to an internal database in under an hour. Defenders must respond in kind, leveraging AI for threat hunting, vulnerability remediation, and incident response while maintaining strict governance to prevent agentic AI from becoming a liability. The integration of threat intelligence directly into recovery workflows, as seen with CommVault and Google, is a critical step toward resilience. Ultimately, the organizations that thrive will be those that treat resilience as a competitive advantage, not a budget line item.

Prediction:

  • -1: The proliferation of autonomous AI agents will lead to a surge in AI-to-AI attacks, where compromised agents are used to launch coordinated, self-propagating campaigns, overwhelming traditional SOCs.
  • +1: The formalization of AI security research, as seen at Black Hat 2026, will accelerate the development of robust defensive frameworks and standards, leading to more resilient enterprise architectures.
  • -1: Organizations that fail to implement AI observability and governance will face significant data breaches and regulatory fines as AI agents inadvertently expose sensitive data.
  • +1: The integration of threat intelligence into backup and recovery workflows will drastically reduce downtime and recovery costs, making cyber resilience a tangible business enabler.
  • -1: The average patch window is already lengthening; with AI accelerating vulnerability discovery, the gap between disclosure and exploitation will continue to shrink, punishing slow patching cycles.
  • +1: The emergence of AI red teaming competitions, such as CrowdStrike’s AI Unlocked challenge, will democratize AI security knowledge and produce a new generation of defenders skilled in securing agentic systems.
