IT Infrastructure Auditing Services

𝗨𝗻𝗱𝗲𝗿𝘀𝘁𝗮𝗻𝗱𝗶𝗻𝗴 𝗜𝗧 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 As an IT Auditor, understanding IT infrastructure is fundamental—it’s the backbone of an organization’s technology environment, supporting everything from servers and networks to cloud platforms and databases.  Assessing risks, controls, and security gaps becomes a challenge without a solid grasp of IT infrastructure 𝟭. 𝗪𝗵𝗮𝘁 𝗶𝘀 𝗜𝗧 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲? IT infrastructure includes all the hardware, software, networks, and services required to operate and manage an organization’s IT environment. Key components include: Hardware: Servers, storage devices, routers, and switches. Software: Operating systems, databases, and enterprise applications. Networks: LANs, WANs, firewalls, and VPNs. Cloud Services: IaaS, PaaS, and SaaS platforms. 𝟮. 𝗪𝗵𝘆 𝗜𝗧 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗠𝗮𝘁𝘁𝗲𝗿𝘀 𝗳𝗼𝗿 𝗔𝘂𝗱𝗶𝘁𝗼𝗿𝘀 IT infrastructure is a prime target for cyberattacks, system failures, and compliance issues. As an IT Auditor, your role is to ensure: Security: Are there vulnerabilities in the infrastructure that could be exploited? Reliability: Is the infrastructure resilient to failures and downtime? Compliance: Does it meet regulatory requirements (e.g., GDPR, SOX, HIPAA)? Efficiency: Is the infrastructure optimized for performance and cost? 𝟯. 𝗞𝗲𝘆 𝗔𝗿𝗲𝗮𝘀 𝘁𝗼 𝗙𝗼𝗰𝘂𝘀 𝗼𝗻 𝗗𝘂𝗿𝗶𝗻𝗴 𝗮𝗻 𝗜𝗧 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗔𝘂𝗱𝗶𝘁 Here are the critical areas to assess: a. Network Security Are firewalls and intrusion detection systems properly configured? Is network traffic encrypted and monitored? Are there open ports or unauthorized devices on the network? b. Server and Storage Management Are servers patched and updated regularly? Is data backed up and stored securely? Are access controls in place to prevent unauthorized access? c. Disaster Recovery and Business Continuity Is there a disaster recovery plan in place? Are backups tested regularly? How quickly can critical systems be restored after a failure? d. Compliance and Governance Does the infrastructure comply with relevant regulations? Are there policies for change management and access control? Is there documentation for all infrastructure components? 𝟰. 𝗖𝗼𝗺𝗺𝗼𝗻 𝗜𝗧 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗥𝗶𝘀𝗸𝘀 𝘁𝗼 𝗪𝗮𝘁𝗰𝗵 𝗙𝗼𝗿 Cybersecurity Threats: Malware, ransomware, and phishing attacks. Hardware Failures: Aging servers or storage devices. Misconfigurations: Open ports, weak passwords, or unpatched software. Third-Party Risks: Vulnerabilities in vendor-managed systems. Compliance Gaps: Failure to meet regulatory requirements. Auditing IT infrastructure is about protecting the organization from risks, ensuring business continuity, and building trust with stakeholders. When IT infrastructure is secure and efficient, the entire organization benefits. #ITAudit #ITInfrastructure #Cybersecurity #RiskManagement #ITGovernance #AuditProfessionals

Do your audit rights actually work, or are they just words on paper? 📝 Most organizations assume that having “audit rights” in a vendor contract is enough. In 2025, that assumption could put you at real risk. Here’s what risk professionals must know right now: Why audit rights are back in the spotlight → DORA (EU) – Now live. Contracts with ICT providers must include real, exercisable audit and information rights, including on-site inspections. → UK PRA updates – Explicitly require audit rights that extend to subcontractors and regulators. → NIS2 Directive – Expands accountability across 18 critical sectors. Strong oversight clauses aren’t optional. → SEC Cyber Disclosure Rule (US) – Four-day incident reporting means you need fast, direct access to vendor evidence. ⚠️ The pain points we see daily → Vendors pushing for “certificates only” instead of real access. → Cloud providers offering pooled audits, but still limiting individual on-site checks. → Missing flow-down rights, your vendor’s subcontractors escape your oversight. → No clause giving direct regulator access to providers (a non-starter under DORA/PRA). 3 things you can act on immediately 1) Review your top 20 vendor contracts – Do they include on-site, regulator, and subcontractor audit rights? If not, flag them for remediation. 2) Tier your audit model – Critical vendors = on-site rights; mid-tier = pooled audits + supplemental evidence; lower-tier = independent reports. 3) Pre-agree evidence menus – Define what you can ask for (SOC 2, vulnerability scans, BCP/DR tests, incident logs) and set SLAs for delivery. 📌 Takeaway: Regulators don’t care what’s in your contract if you can’t actually exercise it. 2025 is the year to test your audit rights, not just file them away. #ThirdPartyRisk #AuditRights #RiskManagement #VendorRisk #tprm #OperationalResilience #ComplianceMatters #CyberRisk #Governance #FinancialServices #RegulatoryCompliance

IT General Controls 101 IT General Controls form the foundation of every reliable system. When ITGCs fail, every automated control built on top of them becomes questionable. Leaders often underestimate this risk. Your role as an IT auditor is to make it visible and actionable. You do not audit ITGCs to check a box. You audit them to establish trust in systems, data, and reporting. 📌 Understand the purpose of ITGC ITGCs support the integrity, confidentiality, and availability of systems. They underpin financial reporting, operational processes, and AI-driven decisions. If ITGCs break, application controls lose credibility. 📌 Know the core ITGC domains You focus on four areas. Logical access. Change management. IT operations. Backup and recovery. These domains cover how systems are accessed, changed, run, and restored. 📌 Logical access controls You test user provisioning, deprovisioning, and role design. You review privileged access. You confirm MFA enforcement. You assess session management and monitoring. Weak access controls remain the top root cause of audit failures. 📌 Change management controls You test how changes move into production. You verify approvals, testing, and segregation of duties. You focus on production systems supporting financial and regulated processes. Uncontrolled changes create hidden risk. 📌 IT operations controls You review job scheduling, monitoring, and incident handling. You confirm failures trigger alerts and follow-up. You assess evidence of daily operational discipline. Silence in operations often signals control gaps. 📌 Backup and recovery controls You test backup completeness and restore capability. You validate RTO and RPO alignment with business needs. You look for restoration testing evidence. A backup with no restore test provides false comfort. 📌 Evidence quality matters You rely on system-generated evidence. Logs. Configurations. Tickets. Reports. You avoid screenshots with no context. You ensure evidence covers the full audit period. 📌 Scope drives value You scope ITGCs to systems that matter. Financial reporting platforms. Customer-facing systems. Data pipelines feeding AI models. You avoid over-auditing low-risk systems. 📌 Reporting with impact You link ITGC gaps to business risk. Downtime. Data exposure. Reporting errors. You help leaders see why ITGCs deserve attention and investment. Strong ITGCs build confidence across the enterprise. Weak ITGCs undermine everything. #ITGC#ITAudit#InternalAudit#CybersecurityAudit#SOX#ITGovernance#RiskManagement#GRC#AuditQuality#TechLeadership

Dear Auditors, Identity & Access Management Audit Most organizations believe they have Identity & Access Management (IAM) under control. Then the audit begins. You ask to see the access review process. They hand you a spreadsheet. You ask how privileged accounts are reviewed. The response is, “Managers check quarterly.” On the surface, it sounds acceptable. But when you dig deeper, you uncover the real risks: 📌 Terminated employees still have active accounts 📌 Shared administrator accounts with no clear accountability 📌 Access review requests sent but never acted upon 📌 Orphaned accounts tied to legacy applications that no one owns This isn’t simply a technology issue. Weak IAM exposes the organization to fraud, insider threats, data breaches, and regulatory non-compliance. What’s more, access governance is not just IT’s responsibility, it’s an enterprise responsibility. HR, compliance, business owners, and leadership must all play a role. As an IT Audit Manager, here’s how I approach IAM audits to uncover risks others often miss: 📌 Policy vs. practice: I review the written policy, but I also verify how it’s enforced in reality. Policies that aren’t implemented create a false sense of security. 📌 Cross-reconciliation: I reconcile user listings from HR, IT, and application systems. Inconsistencies often highlight weak offboarding or improper role assignments. 📌 Business-critical access: I don’t stop at infrastructure. I evaluate access to ERP systems, SaaS platforms, financial applications, and other sensitive tools where a single excessive permission can cause major damage. 📌 Role-based access design: I assess how roles are defined, assigned, and monitored. Poorly designed roles often lead to toxic combinations of access that no one notices until it’s too late. 📌 Lifecycle controls: I trace joiner, mover, and leaver events. The question is simple, does the system adjust access automatically and completely when people change roles or leave? 📌 Exception and alerting mechanisms: I check if high-risk access changes trigger alerts or approvals. If there’s no timely detection, privilege abuse can go unnoticed for months. 📌 Shared accountability: I interview IT, HR, and business owners. Access governance only works when responsibility is shared across the organization. IAM is not about provisioning accounts quickly. It’s about ensuring trust, accountability, and compliance. The goal is clear: the right people, with the right access, at the right time, and no one else. An IAM audit done right does more than close a control gap. It protects the organization’s reputation, customer trust, and compliance standing. In Cybersecurity, IAM is where technology, governance, and human behavior intersect. If you only audit the technology, you will miss the true risks. #IAMAudit #AccessControls #CyberAudit #ITAudit #IdentityManagement #GRC #InternalControls #PrivilegeReview #CyberVerge #CyberYard

Dear IT Auditors,   When scoping IT audits, it’s easy to get lost in system details: Active Directory, databases, cloud platforms, backups… the list never ends. But here’s a secret I’ve learned for some time now: ➡️ Annex A of ISO 27001 is the best starting point for any IT audit. Why? Because Annex A outlines 93 controls (in the 2022 version) that cover the entire landscape of IT risks. Whether or not your organization is formally ISO-certified, these controls act as a roadmap.   Here’s how I use it in practice: 1️⃣ Access Control (A.5.15) – Helps me frame questions around onboarding, offboarding, role-based access, MFA, and privilege reviews. 2️⃣ Ensures I’m not just checking user lists but also looking for the principle of least privilege in action. 3️⃣ Operations Security (A.8) – Guides reviews of backup procedures, change management, patching, and logging. – Forces me to ask: “What happens if this fails?” not just “Is it documented?” 4️⃣ Supplier Relationships (A.5.19 – A.5.23) – Reminds me to consider vendor access, third-party risk, and SLA enforcement. – Because a weak vendor can be the weakest link. 5️⃣ Communications and System Acquisition (A.5.10, A.8.31, etc.) – Frames my review of system development, secure coding, and testing environments. – Encourages me to connect IT audit work with broader cyber hygiene practices. 6️⃣ Incident Management & Business Continuity (A.5.24 – A.5.30) – Pushes me to test whether incident response and disaster recovery are more than “documents on a shelf.” – Keeps resilience in scope, not just compliance.   Here’s the key insight: Annex A isn’t just for ISO auditors. It’s a common language that bridges IT, business, and compliance. If you’re auditing cloud services, fintech platforms, ERP systems, or even ITGCs for financial reporting, starting with Annex A ensures your audit scope is comprehensive, risk-based, and globally aligned. So next time you’re planning an IT audit, don’t reinvent the wheel. Open Annex A. Use it as your cheat sheet.   Because the best auditors don’t just look at systems, they look at systems through the lens of standards. (A wise man once told me this)   #ISO27001 #AnnexA #ITAudit #CyberCompliance #InternalAudit #GRC #RiskManagement #CyberSecurityStandards #AuditorTips

Cloud Audit A cloud audit means checking if a company’s cloud systems are safe, well controlled, and following required rules like SOX, GDPR, or ISO. Today, many companies use cloud services like Oracle Cloud, AWS, Azure, or Salesforce instead of managing their own servers. This changes the way audits are done. In cloud systems, some parts are handled by the cloud provider, and some parts are managed by the company using the cloud. This is called shared responsibility. For example, the cloud provider takes care of things like physical security and server setup. The company is responsible for things like user access, data protection, and reviewing activity logs. There are three common types of cloud services. In Infrastructure as a Service (IaaS), the company manages the operating system and firewall. In Platform as a Service (PaaS), the company uses tools like databases but does not manage the full system. In Software as a Service (SaaS), like Oracle Fusion or Salesforce, the provider manages everything except for the company's users and data. If a company uses Oracle Fusion Cloud for finance work, they cannot test the server or network controls because Oracle handles that. Instead, the auditor uses Oracle’s SOC 1 Type 2 report. This report is prepared by an independent auditor and tells whether Oracle's controls were working properly during the year. The company must still do their part, such as reviewing user access, managing roles, and following their own internal controls. If they don’t do this, the auditor cannot fully rely on Oracle’s report. Some key areas to check in a cloud audit include: Who has access to the system and data Whether multi-factor authentication is enabled Whether important data is encrypted If changes to systems are tracked properly If logs and alerts are active Whether data is backed up and tested for recovery If third-party reports are used and understood. To perform a cloud audit, first understand the system architecture. Ask the client to explain what cloud services they use and how they use them. Then, find out which controls are managed by the provider and which are the client’s responsibility. Always check if the client has reviewed the cloud provider’s SOC report. Also confirm if they have done their own part of the control work. For example, if the report says that the company must do user access reviews every quarter, check if they are really doing it. Common mistakes in cloud audits include relying on SOC 1 Type 1 reports instead of Type 2, ignoring the customer responsibilities listed in the report, assuming the cloud provider handles everything, or missing key risks like unrestricted user access or no data backup testing. In summary, cloud audit is about focusing on what the company controls in the cloud and using trusted reports to cover what the cloud provider manages. It requires good understanding, careful planning, and checking both the company’s and the provider’s roles. #itgc #itsox

🚀 How to Scope IT SOX ITGCs in Under 2 Hours (Using PCAOB Risk-Based Criteria) Most companies over-scope ITGCs… and still miss the areas PCAOB actually cares about. You don’t need 3 weeks to build a defensible SOX scope. You just need a repeatable, PCAOB-aligned, risk-based workflow. Here’s the 2-hour method top IT audit functions use 👇 🕒 1. Start With Financial Statement Materiality (10 min) Identify material FS accounts and key classes of transactions. This anchors your IT scope directly to PCAOB AS 2201. 🖥️ 2. Map Processes to Systems (20 min) List all systems supporting these processes: • ERP modules • Key SaaS apps • Databases • Data transformation/ETL tooling • IAM + logging systems Group them as: 🔹 Critical Financial Systems 🔹 Supporting Systems 🔹 Infrastructure 🎯 3. Apply PCAOB Risk-Based Criteria (40 min) Score each system on: • Financial statement impact • Potential for material misstatement • Volume + complexity • Automations + integrations • Completeness & accuracy reliance Include: High-risk systems and anything relied upon for C&A Exclude: Low-risk SaaS tools with no direct financial impact 🔐 4. Determine Required ITGC Domains (20 min) For each in-scope system, decide if you need to test: ✔ Access management ✔ Change management ✔ IT operations (backups, jobs, monitoring) ✔ Interfaces & data integrity Avoid blanket testing. Scope by system type and risk. 🤝 5. Validate With External Audit (10 min) Share the draft scope, confirm assumptions, and lock in coverage. This eliminates Q4 scope creep and reduces downstream rework. 💡 Common Pitfalls (and How to Avoid Them) 🚫 Over-scoping cloud infrastructure 🚫 Assuming SOC 2 = SOX coverage 🚫 Including every SaaS tool 🚫 Ignoring CUECs 🚫 Not tying scope to materiality Solution: Always tie scoping decisions back to PCAOB risk-of-material-misstatement criteria. 🏁 Final Thought Effective ITGC scoping isn’t about length—it's about precision. Get this right, and you reduce testing, avoid surprises, and strengthen your entire SOX program. #SOX #ITSOX #SOXCompliance #ITAudit #TechnologyRisk #GRC #InternalAudit #PCAOB #RiskManagement #TechCompliance #SOX404 #ITGC #ITControls #AuditLeadership #CISO #TechRiskLeaders #FinanceTransformation #SOXProgram #CloudCompliance #SaaSCompliance
