Introduction
The global cybersecurity workforce gap is projected to reach 3.5 million unfilled positions by 2025, and organizations worldwide are urgently hiring skilled IT professionals. SISL Global, a premier Managed Service Provider operating in 190+ countries with a 99% customer satisfaction rate, is actively recruiting an Information Technology Support Engineer in Madrid. This role demands a unique blend of traditional support skills and modern security expertise, including remote monitoring and management (RMM), endpoint protection, and automation.
Learning Objectives
- Master enterprise RMM platforms like NinjaOne and SentinelOne to proactively manage global IT infrastructure
- Automate patch management and security compliance using PowerShell scripts and Azure tools
- Integrate AI-driven SIEM automation with incident response workflows for enhanced threat detection
- Implement Microsoft Intune Autopilot, Zero Trust principles, and Conditional Access Policies
You Should Know
1. Mastering RMM: Your 24/7 IT Command Center
RMM software transforms your workflow from reactive firefighting to proactive system management. Enterprise-level platforms track CPU usage, memory, disk space, network performance, and application health across thousands of endpoints.
Step-by-Step Guide to Deploy RMM Agents
- Agent Deployment: Use Group Policy or Intune to silently deploy RMM agents. Example PowerShell deployment script:
Deploy NinjaOne agent via PowerShell $installerUrl = "https://your-rmm-installer-url/agent.msi" $installerPath = "$env:TEMP\rmm_agent.msi" Invoke-WebRequest -Uri $installerUrl -OutFile $installerPath msiexec /i $installerPath /quiet /norestart /qn
-
Configuration Management: Apply device compliance profiles and configuration policies to Windows, Android, and iOS devices.
-
Monitor Key Metrics: Set threshold alerts for critical KPIs such as CPU usage >90%, disk free space <10GB, and memory leaks.
-
Remote Troubleshooting: Use secure remote desktop access to fix issues without physical presence. Always enable session logging for compliance in regulated industries.
-
Automate Maintenance: Schedule disk cleanup, registry optimization, and system updates to run automatically outside business hours.
Linux CLI Alternative: For Linux environments, use command-line tools to monitor system health:
Monitor CPU, memory, and disk usage htop free -h df -h Check system logs for errors journalctl -p err -b
2. Patch Management Automation: Slay Vulnerabilities at Scale
Patch drift occurs when endpoints miss critical security updates, degrading your security posture over time. SISL Global requires practical understanding of patch management best practices across hybrid infrastructure.
Step-by-Step Guide to Automate Patch Audits
- Define a Patch Baseline: Establish required KBs or CVEs to measure patch compliance consistently across all endpoints.
2. Detect Missing Patches with PowerShell:
Define baseline KBs
$baselineKBs = @("KB5030211", "KB5029263")
Query installed patches
$installed = Get-HotFix | Select-Object -ExpandProperty HotFixID
Find missing patches
$missing = $baselineKBs | Where-Object { $installed -notcontains $_ }
if ($missing.Count -gt 0) {
Write-Host "Missing critical patches: $missing"
}
3. Deploy Patches Using Azure Update Manager:
Create maintenance configuration for automatic patching New-AzVMSqlServerAutoPatchingConfig -DayOfWeek Sunday -MaintenanceWindowDuration 120
4. Verify Compliance with CMD:
wmic qfe list brief /format:texttable systeminfo | find "Hotfix"
- Monitor Patch Drift Using RMM: Write “MissingKBs” and timestamps to the registry so RMM tools can monitor compliance centrally.
3. Endpoint Protection and Zero Trust Security
Modern IT support engineers must implement layered defense strategies. Endpoint Detection and Response (EDR) platforms like Microsoft Defender ATP and SentinelOne provide real-time threat hunting capabilities.
Step-by-Step Guide to Implement Zero Trust Security
- Enforce Multi-Factor Authentication: Enable MFA for all users accessing corporate resources using Conditional Access Policies.
2. Implement Intune Device Compliance:
Intune PowerShell detection script example
$complianceStatus = Get-DeviceComplianceStatus
if ($complianceStatus -ne "Compliant") {
Write-Host "Device non-compliant, blocking access"
}
- Deploy Endpoint Security Baselines: Use CIS Benchmarks to harden Windows and Linux systems.
-
Configure Network Segmentation: Implement VLANs and DMZs to isolate critical assets. Use FortiGate firewall rules to restrict lateral movement.
-
Enable Least Privilege Access: Implement role-based access control and limit administrative privileges to essential personnel only.
4. AI-Driven Security Operations and Incident Response
The integration of AI into SIEM platforms transforms threat detection and incident response. AI-driven SIEM automation enables real-time security monitoring and faster response times.
Step-by-Step Guide to Integrate AI with SIEM
- Deploy a SIEM Platform: Implement solutions like Splunk, Azure Sentinel, or Elastic Stack for centralized log management.
-
Normalize Log Data: Ensure logs are formatted in CEF, Syslog, or JSON for seamless ingestion.
-
Train AI Models: Use historical attack patterns to train machine learning models for anomaly detection.
-
Create Automated Playbooks: Develop SOAR workflows that automatically isolate compromised endpoints and revoke access tokens.
-
Integrate Human Behavior Analytics: Connect security awareness platforms with SIEM to detect risky user activities in real-time.
Linux Command for Log Analysis:
Parse syslog for authentication failures
grep "Failed password" /var/log/auth.log | awk '{print $1,$2,$3,$9,$11}' | sort | uniq -c
5. Cybersecurity Awareness Training and Human Risk Reduction
Approximately 60% of cybersecurity breaches involve the human element. Security awareness training that includes voice, SMS, and helpdesk simulation reduces organizational risk.
Step-by-Step Guide to Implement Security Awareness Training
- Conduct Phishing Simulations: Run monthly simulated phishing campaigns targeting all employees.
-
Helpdesk Mode Testing: Simulate social engineering attacks against support queues to identify weaknesses.
-
Track Metrics: Monitor click-through rates, reporting rates, and time-to-report for security incidents.
-
Integrate with SIEM: Feed training results into SIEM for real-time risk scoring and intervention.
-
Continuous Improvement: Use AI to personalize training content based on individual risk profiles.
What Undercode Say
-
Security-first mindset is non-negotiable: SISL Global’s hiring data shows 65% of job descriptions contain compliance and regulatory keywords, confirming that security awareness is now a core requirement for IT support roles.
-
Automation skills separate average from exceptional: Candidates proficient in PowerShell scripting and RMM automation can manage 10x more endpoints than those relying on manual processes, making them invaluable for global MSPs.
-
Zero trust is the new perimeter: Traditional castle-and-moat security is dead. IT support engineers must understand micro-segmentation, MFA, and least privilege access to protect distributed enterprise environments.
Prediction
By 2028, AI-powered IT support assistants will handle 75% of Level 1 tickets, forcing support engineers to specialize in security automation, threat hunting, and incident response. Organizations like SISL Global will prioritize candidates who combine traditional support skills with cybersecurity expertise and automation capabilities, creating a new hybrid role: the Security-Support Automation Engineer. Madrid’s growing tech ecosystem will see increased demand for these roles, with salaries rising 30% faster than traditional IT positions.
