Stay secure and compliant with global standards like ISO 27001, GDPR, and NIST, SidigiQor audit experts ensure you meet every cybersecurity and data regulation. Cybersecurity is ultimately about people: patients receiving care, families relying on utilities, students learning online, and employees earning a living. When networks fail or are breached, the human consequences are real.

At Sidigiqor Technologies we run pragmatic, humane network security audits across the Gulf and Europe focused on protecting lives, livelihoods and essential services. Below is our detailed 12-point Network Security Audit Checklist — each point explained with actions, tools, outcomes and remediation guidance.

1. Review Network Architecture

What to do: Map the entire network — physical and logical topology, data flows, device roles and management paths.
Tools: NetBox, draw.io, Nmap, network inventory tools.
Why it matters: A current network diagram reveals single points of failure and insecure management paths. In healthcare or utilities (common clients in Kuwait and Germany) a correct topology prevents accidental exposure of control systems.
Audit actions: Validate diagrams, confirm segmentation boundaries, identify admin interfaces and out-of-band management networks.
Remediation: Standardize diagrams, enforce documented change control and lock down management interfaces.

2. Assess Network Segmentation

What to do: Verify VLANs, firewalls and zone boundaries that isolate sensitive assets (SCADA, finance, HR).
Tools: Firewall configs, segmentation mapping (Cisco ACI), packet captures.
Why: Segmentation limits attacker lateral movement — a critical control for oil & gas in the UAE and manufacturing in Germany.
Audit actions: Test cross-segment traffic, validate ACLs and micro-segmentation policies.
Remediation: Implement stricter ACLs, enforce least-privilege flows and consider software-defined micro-segmentation.

3. Evaluate Firewall Configuration

What to do: Review firewall rulesets for policy drift, overly permissive rules and stale entries.
Tools: Firewall management platforms (pfSense, Cisco ASA, Palo Alto Panorama).
Why: Misconfigurations are a top cause of breaches worldwide.
Audit actions: Compare rules to documented policy, remove “any→any” rules, document business justification.
Remediation: Implement rule-review cadence, rule naming standards and change approval.

4. Test Intrusion Detection / Prevention (IDS/IPS)

What to do: Validate IDS/IPS sensors are deployed, tuned and logging correctly.
Tools: Snort, Suricata, commercial NDR.
Why: IDS/IPS detect lateral movement, suspicious protocol anomalies and known exploit signatures.
Audit actions: Test with controlled attack simulations, verify alerts and response playbooks.
Remediation: Tune signatures to reduce false positives and integrate with SOC workflows.

5. Scan for Vulnerabilities

What to do: Run authenticated and unauthenticated scans of network devices and servers.
Tools: Nessus, OpenVAS, Qualys.
Why: Vulnerability scanning uncovers missing patches, default credentials or risky services.
Audit actions: Schedule scans, prioritize critical CVEs, surface high-risk hosts in public-facing subnets.
Remediation: Patch, mitigate via compensating controls (WAF, virtual patching) and validate fixes.

6. Verify Access Controls

What to do: Review IAM, Active Directory, VPN logs and service accounts.
Tools: AD auditing tools, IAM consoles, VPN logs.
Why: Wrong permissions lead to privilege abuse. Especially important for financial institutions in Bahrain and public organisations in the UK.
Audit actions: Check admin account usage, orphaned accounts, remote vendor access and shared credentials.
Remediation: Enforce least privilege, remove stale accounts, require MFA and use Privileged Access Management (PAM).

7. Review Network Access Logs (SIEM)

What to do: Analyse logs for unusual connections, authentication failures and lateral movement.
Tools: Splunk, ELK/Elastic Stack, Azure Sentinel.
Why: Logs reveal early reconnaissance and long-term stealth activity.
Audit actions: Ensure time sync, log retention, and alert tuning. Look for brute force, suspicious geolocations, data exfil patterns.
Remediation: Implement detection rules, improve alerting quality, establish incident escalation.

8. Check Encryption Protocols

What to do: Validate TLS/SSL versions, cipher suites and certificate management.
Tools: SSL Labs, Wireshark, OpenSSL checks.
Why: Weak encryption exposes data in transit; expired certs break trust. Critical for cloud services in Oman and EU GDPR compliance.
Audit actions: Scan public endpoints and internal services for outdated protocols (TLS1.0/1.1), weak ciphers or self-signed certs.
Remediation: Enforce TLS1.2/1.3, implement certificate lifecycle management and HSTS where appropriate.

9. Evaluate Remote Access Security

What to do: Audit VPNs, remote desktop gateways, jump servers and third-party vendor access.
Tools: VPN logs, Remote Desktop Gateway configs, Citrix/AnyConnect audits.
Why: Remote access is a frequent attack vector. Protecting health services and remote workers in Kuwait and France is a priority.
Audit actions: Confirm MFA, session logging, just-in-time access and IP restrictions.
Remediation: Implement ZTNA, MFA, session recording and strict vendor control.

10. Assess Patch Management

What to do: Review patch cadence across network devices, servers and applications.
Tools: WSUS, SolarWinds, SCCM.
Why: Unpatched systems are low-hanging fruit for attackers.
Audit actions: Check patch compliance, exception handling and test windows.
Remediation: Automate patching where safe, maintain inventory and use phased rollouts for critical systems.

11. Test Backup & Recovery Plans

What to do: Verify backups, run restore tests, validate RPO/RTO and immutability.
Tools: Backup appliances, cloud snapshots (AWS/Azure), recovery runbooks.
Why: Ransomware and disasters require reliable recovery to save services and lives.
Audit actions: Test restores to isolated environment, check encryption of backups and offsite replication.
Remediation: Implement immutable backups, document recovery steps and train teams via drills.

12. Review Third-Party Vendor Security

What to do: Evaluate vendor risk, SLAs and security posture of managed service providers.
Tools: Vendor risk platforms, questionnaires, SOC reports.
Why: Supply chain compromises have broad cascading effects. Many Gulf & EU organisations rely on global vendors.
Audit actions: Require security questionnaires, review third-party penetration test results, ensure contractual security clauses.
Remediation: Enforce vendor controls, limit third-party access, and require incident notification and insurance.

Humanitarian & Operational Perspective

Network security isn’t only technical — it’s about protecting communities. A robust audit prevents downtime at hospitals, keeps telecoms functioning for families, and ensures utilities run smoothly. Sidigiqor’s auditors always consider the human impact when prioritizing mitigations: critical systems that support healthcare, water, energy and emergency services come first.
