This involves identifying potential threats and vulnerabilities, assessing the potential impact of those threats should they materialise, and evaluating the likelihood of their occurrence. For instance, a threat that could cause significant damage and is likely to occur would be given a high priority.
Once we have identified and prioritised the risks, we develop a risk treatment plan. This involves deciding on the most appropriate way to deal with each risk. Options can include accepting the risk, avoiding the risk, transferring the risk (e.g., through insurance), or mitigating the risk through the implementation of security controls.
The choice of mitigation measures is guided by the nature of the risk, its potential impact, and its priority. We generally aim to apply the principle of 'defence in depth', implementing multiple layers of security controls to provide redundancy and ensure that no single point of failure exists.
Once mitigation measures have been implemented, we continue to monitor and review the risks, adjusting our priorities and strategies as necessary. This is a dynamic process, as the threat landscape is constantly changing and evolving.
For instance, if we identified SQL injection as a high-risk threat to our application, we might prioritise input validation and parameterised queries as key security controls. On the other hand, for a lower-risk threat, we might decide that the existing controls are sufficient and that additional measures would not be cost-effective.
In essence, our approach is to continuously assess, prioritise, and treat risks, ensuring that our resources are effectively utilised to reduce risk to an acceptable level 🛡️."

🚧🔒 "Finally, how do you ensure ongoing testing and maintenance of application controls to minimize the risk of security incidents?"
"We have a comprehensive strategy in place to ensure the ongoing testing and maintenance of our application controls, which aims to minimise the risk of security incidents.
Firstly, we conduct regular audits of our application controls. These audits, carried out both internally and by external third parties, help to ensure that our controls are functioning as expected and that they continue to align with our security objectives.
In addition to these audits, we perform regular vulnerability assessments and penetration testing. These exercises simulate the tactics and techniques of potential attackers, helping us to identify any weaknesses in our application controls before they can be exploited in a real-world scenario.
We also make use of automated security scanning tools. These tools are integrated into our development pipeline and can identify common security issues in real-time as code is being developed.
When it comes to maintenance, we have a robust patch management process in place. This ensures that our applications are always up-to-date with the latest security patches and updates, minimising the risk of exploitation.
Moreover, we closely monitor the security landscape for emerging threats and vulnerabilities. When new risks are identified, we can quickly assess their potential impact on our applications and implement any necessary mitigations.
Finally, we invest in continuous training and education for our team. This ensures that they stay up-to-date with the latest security practices and can effectively maintain our application controls.
In short, through a combination of regular testing, proactive maintenance, and ongoing education, we aim to keep our application controls robust and effective, minimising the risk of security incidents 🚀."

Business Continuity and Disaster Recovery:🌪🔥🌊

In today's digital era, the role of IT in underpinning almost every aspect of an organisation's operations cannot be understated. From communications 📞 and financial transactions 💳 to daily business processes and customer interactions, IT systems lie at the heart of business functionality. However, what happens when the unexpected strikes, such as a cyberattack 💻⚠️, natural disaster 🌊🔥, or infrastructure failure 🏢❌? The answer lies in two interconnected strategies: Business Continuity (BC) and Disaster Recovery (DR).

1. Business Continuity: Preparing for the Worst 🚧⏳

BC planning revolves around the concept of ensuring that essential business operations continue to function during and after a disruptive event. It's not just about recovering IT systems, but also about considering how the business can continue to operate if, for instance, a key data centre is inaccessible or a major software application crashes.

A robust BC strategy considers:

- Risk Assessments 📋: Understanding potential threats to the business, their likelihood, and the potential impacts.

- Impact Analysis 💥: Evaluating how interruptions might affect different aspects of the business. This might involve reviewing how a loss of specific IT systems would impact daily operations, customer relations, or financial turnover.

- Strategies and Protocols 📘: These are predefined courses of action that guide businesses during a disruption. It can involve things like rerouting network traffic, moving to temporary offices, or employing remote working 🏡💼.

2. Disaster Recovery: Rebuilding and Recovering 🛠⏲

While BC focuses on maintaining operations, DR zeroes in on the restoration of IT systems after a disaster. This includes data recovery, hardware and software restoration, and getting network infrastructure back online.

Key DR considerations include:

- Data Backups 📦🔒: Regularly backing up data to secure off-site locations ensures that data can be restored swiftly.

- Recovery Time Objective (RTO) ⏱: This is the maximum duration of time a business can function without a specific service or application.

- Recovery Point Objective (RPO) 📈: This defines the age of files that must be recovered from backup storage for normal operations to resume. In simpler terms, it denotes how 'old' the restored data can be.

Why Are BC and DR Paramount in IT and InfoSec? 🛡🌐

Given the ever-evolving landscape of cybersecurity threats and the escalating sophistication of cyberattacks, businesses are in the crosshairs more than ever. A single security breach can compromise sensitive data, denting company reputation and incurring hefty financial losses.

- Ransomware Threats: With ransomware attacks on the rise, having a DR plan can be the difference between paying a hefty ransom and restoring systems to their former state from backups 🔄🔐.

- Data Integrity: Following a cyber breach, it's crucial to have measures in place to verify the integrity of data and systems. This is where BC and DR come hand-in-hand with InfoSec practices.

- Regulatory Compliance: For many sectors, particularly finance and healthcare, regulatory bodies require companies to have a BC and DR plan in place. Non-compliance can result in heavy penalties 💷❌.

Concluding Thoughts 🌐🔚

In the interwoven worlds of IT and InfoSec, BC and DR aren’t just best practices, but essentials. Businesses that proactively invest in these strategies not only safeguard their operations, assets, and reputation but also enhance resilience against the unforeseen. In a world where uncertainty is a given, preparation and proactive strategy remain the best lines of defence. 🛡🌟

Unveiling the Secrets of Joiners/Leavers Testing on MS Windows 🕵️‍♀️💼

Greetings, tech aficionados! Today, we're diving deep into the rabbit hole 🐰 of IT auditing by tackling an evergreen issue—Joiners/Leavers testing for Windows accounts. And guess what? We're doing it the techie way, using PowerShell scripts! 🎩🐇

Setting the Stage 🎭

Joiners and Leavers are like the revolving door 🚪 of your IT environment. You've got newbies needing access (Joiners) and folks clocking out for the last time (Leavers). So, how do you keep tabs on these changing roles without tearing your hair out? 🤯

Enter PowerShell—a knight in shining armour for the IT auditor. ⚔️

Getting Hands-on 🤲

1️⃣ PowerShell for New Account Creation 🆕

If you've got the technical chops, PowerShell is a goldmine. 🏆 Run this basic script to fetch newly created accounts:

powershell
Get-LocalUser | Where-Object {$_.Enabled -eq $true -and $_.LastLogon -le (Get-Date).AddDays(-7)}

2️⃣ The Human Element: HR Data 📋

Let's not put all our eggs in one basket 🧺. Cross-reference the PowerShell data with what HR has in its treasure trove. Often, you can get this directly as a spreadsheet or extract it from an HR system using APIs.

Marrying the Two 💍

Let's do a ‘joining of hands’ 👐 between the PowerShell data and the HR data. You could use Excel's VLOOKUP function or, for those who like living on the edge, another PowerShell script to correlate the two sets.

powershell
# Assuming $hrData and $psData hold our two sets
Compare-Object $hrData $psData -Property Username

Independent Leavers Extraction 🎣

Sometimes HR may not be as quick on the draw 🤠. We can independently extract leaver data using PowerShell.

powershell
Get-LocalUser | Where-Object {$_.Enabled -eq $false -and $_.LastLogon -le (Get-Date).AddDays(-30)}

When Two Worlds Collide 🌍🌏

What's the end game? 🔚 You should be able to identify discrepancies like:

- New accounts not yet documented by HR 🤷
- Accounts belonging to leavers that are still active 🧟‍♂️

The Final Curtain Call 🎭

Performing Joiners/Leavers testing isn’t just crossing the t’s and dotting the i’s; it's essential for keeping your digital fortress 🏰 secure. With PowerShell and some good old HR data, you can be your company's unsung hero! 🦸‍♂️

So, folks, this isn't just a flash in the pan; it's a tried and tested method to keep your IT environment as clean as a whistle. 🎶 Until next time, keep those scripts running! 🏃‍♀️💻

Happy Auditing! 🕵️‍♀️🌈

SAP Modules IT Audit: A Deeper Look 🧐

SAP systems are vast and intricate. As we know, the devil is often in the details. Let's dig deeper into privileged access and change management within our focus modules.

🔍 Privileged Access

Ensuring that only the right individuals have elevated privileges is crucial.

Example: If a user has access to transaction codes (t-codes) such as SE38 (for running ABAP programs) or SE93 (for creating custom t-codes), they can potentially bypass business controls.

Audit Script for Privileged Access:

SELECT DISTINCT A~USRNAME, B~TCODE
FROM S_USER_AUTH AS A
JOIN S_TCODE AS B ON A~PROFN = B~PROFN
WHERE B~TCODE IN ('SE38', 'SE93');

This script fetches users with potentially risky t-codes. Such access should be regularly reviewed and justified.

📌 Audit Tip: Always verify the purpose for having privileged access. Temporary access for projects should be revoked immediately after completion.

🔍 Change Management

Changes to system configurations or custom developments can introduce risks if not properly managed.

Example: SAP's Transport Management System (TMS) manages the movement of changes. Unauthorized or untested transports can result in business disruptions.

Audit Script for Change Transports:

SELECT KORR, ERNAM, AS4USER, TRKORR, OBJECT
FROM E070
WHERE TRKORR LIKE 'D%' AND ERDAT BETWEEN '[Start Date]' AND '[End Date]';

This identifies changes in the development system. You'd want to ensure these are properly documented, tested, and authorised.

📌ELECT DISTINCT ATrack changes from development through to production. Every transport should have corresponding documentation and approval.

🔍 Segregation of Duties (SoD)

SoD conflicts can lead to fraud if a single user can perform conflicting tasks, e.g., create a vendor and approve payments to that vendor.

Example: In the MM module, t-codes MK01 (Create Vendor) and FB60 (Enter Vendor Invoice) should not be assigned to the same user.

Audit Script for SoD:

SELECT USRNAME
FROM S_USER_AUTH
WHERE PROFN IN (SELECT PROFN FROM S_TCODE WHERE TCODE IN ('MK01', 'FB60'))
GROUP BY USRNAME HAVING COUNT(DISTINCT TCODE) > 1;

This identifies users with potential SoD conflicts in the MM module.

📌 Audit Tip: Implement automatic SoD checks using tools like SAP Access Control to regularly monitor and report potential conflicts.

🛡️ Wrap-Up: Delving into the specifics of SAP makes it clear that an effective audit requires a mix of technical and functional understanding. Always be proactive and keep abreast of the latest SAP developments and risks.

Remember: In-depth SAP audits can reveal unnoticed vulnerabilities. Stay curious and diligent! 🔎✨

Case Study: Change Management Controls and Segregation of Environments in SAP R3 and Oracle EBS
Introduction
Change management controls and segregation of environments are essential for maintaining the integrity and security of enterprise resource planning (ERP) systems such as SAP R3 and Oracle EBS. ERP systems store and process critical business data, so it is important to have robust controls in place to manage changes and prevent unauthorized access.
Change Management Controls
Change management controls are a set of processes and procedures that ensure that changes to ERP systems are made in a controlled and authorized manner. These controls typically include the following steps:
Change request: A change request is initiated by a user or business process owner who needs a change to be made to the ERP system. The change request should describe the change in detail, including the reason for the change, the impact on the system, and the proposed implementation plan.
Change review and approval: The change request is reviewed and approved by a change management board (CMB). The CMB is a group of individuals responsible for assessing the impact of changes and approving or rejecting them.
Change implementation: Once the change is approved, it is implemented by a qualified team of technicians. The team should follow the approved implementation plan and test the change thoroughly before it is deployed to production.
Change deployment: Once the change has been tested and approved, it is deployed to the production environment. The deployment should be closely monitored to ensure that it is successful.
Post-change review: After the change has been deployed, it is important to conduct a post-change review to verify that it has been implemented correctly and that it is meeting its intended purpose.
Segregation of Environments
Segregation of environments is the practice of separating ERP systems into different environments, such as development, testing, and production. This separation of environments helps to prevent unauthorized changes from being made to the production environment and to minimize the impact of changes on production operations.
Practical Examples
Here are some practical examples of change management controls and segregation of environments in SAP R3 and Oracle EBS:
Extracting changes in SAP R3: To extract changes in SAP R3, you can use the Transaction Change Monitor (TCODE: SCC3). The SCC3 transaction allows you to view and track all changes that have been made to SAP objects, such as tables, programs, and function modules.
Sampling changes in SAP R3: To sample changes in SAP R3, you can use the following script:

SELECT * FROM SCC3
WHERE CHANGEDATE BETWEEN '2023-09-19' AND '2023-09-20'
ORDER BY RAND()
LIMIT 100;

This script will select a random sample of 100 changes that were made to SAP objects between September 19 and 20, 2023.
Extracting changes in Oracle EBS: To extract changes in Oracle EBS, you can use the Change Management workbench. The Change Management workbench allows you to view and track all changes that have been made to Oracle EBS objects, such as tables, programs, and forms.
Sampling changes in Oracle EBS: To sample changes in Oracle EBS, you can use the following SQL query:

SELECT * FROM EBS_CHANGE_HISTORY
WHERE CHANGE_DATE BETWEEN '2023-09-19' AND '2023-09-20'
ORDER BY RAND()
LIMIT 100;

This query will select a random sample of 100 changes that were made to Oracle EBS objects between September 19 and 20, 2023.
Conclusion
Change management controls and segregation of environments are essential for maintaining the integrity and security of ERP systems such as SAP R3 and Oracle EBS. By following the best practices outlined in this case study, you can help to ensure that changes to your ERP system are made in a controlled and authorized manner.

Case Study: Navigating the Maze of SOC Reporting in IT Audit with Multiple Subservice Organisations

Introduction 📑
In the realm of IT Audit and Information Security, SOC (System and Organisation Controls) reports and ISAE (International Standard on Assurance Engagements) frameworks serve as the cornerstone for assuring robust control environments. However, when multiple subservice organisations come into play, the audit landscape becomes increasingly complex. This case study aims to dissect this complexity by providing practical examples that apply SOC and ISAE frameworks.

Methodologies 🛠️
There are two primary methods for including subservice organisations in a SOC report:

Carve-Out Method: The subservice organisation's controls are explicitly excluded from the service organisation's SOC report.
Complementary Subservice Organisation Controls: The subservice organisation's controls are included within the scope of the service organisation's SOC report.
Let's dive into two abstract examples to understand these methods better.

Case Study 1: FinTech Corp 🏦 - Carve-Out Method

Background 🌐
FinTech Corp is a financial technology company that utilises a third-party cloud service provider (Cloudify Inc.) for its data storage and another third-party payment gateway (PayRight) for processing transactions.

Problem Statement ❗
FinTech Corp needs to undergo a SOC 2 audit but is unsure how to deal with its subservice organisations, Cloudify Inc. and PayRight.

Solution 💡
FinTech Corp opted for the Carve-Out Method. In its SOC 2 report, it explicitly stated that Cloudify Inc.'s and PayRight's controls were not covered. It mentioned that for a comprehensive understanding of the control environment, user entities should consult the SOC reports of Cloudify Inc. and PayRight.

Takeaways 🎓
Less complex for FinTech Corp
Shifts responsibility to user entities to get the complete picture
Easier to implement but potentially less thorough


Case Study 2: HealthMate 🏥 - Complementary Subservice Organisation Controls

Background 🌐
HealthMate is a healthcare provider that uses multiple third-party services, including a cloud-based Electronic Health Record (EHR) system and a payment processor.

Problem Statement ❗
HealthMate is subject to stringent data protection laws and needs to include its third-party services in its SOC 2 report.

Solution 💡
HealthMate chose the Complementary Subservice Organisation Controls method. They included the controls of their EHR and payment processor within their SOC 2 report's scope. This required rigorous assessment and coordination with the subservice organisations.

Takeaways 🎓
Provides a more holistic view of the control environment
More complex to implement
Requires strong collaboration between the service and subservice organisations


Conclusion 🎬
The selection between the Carve-Out and Complementary Subservice Organisation Controls methods is not a one-size-fits-all decision. The Carve-Out Method is simpler but may leave gaps in assurance. On the other hand, the Complementary Subservice Organisation Controls method is more comprehensive but requires a higher level of effort and collaboration.

Governance in Cybersecurity

Cybersecurity is not a one-size-fits-all venture. The unique nature of every organisation demands a tailored approach to ensure robust security. A well-rounded governance structure is the cornerstone to achieving this, and the NIST Cybersecurity Framework (CSF) provides a thorough guide to making this a reality. Let’s delve into the Governance (GV) subcategory of the IDENTIFY domain, breaking down its essential components. 🛡️

1. Establishing and Communicating Cybersecurity Policy (ID.GV-1) 📜

The formulation of a comprehensive cybersecurity policy is a fundamental step. This policy outlines how an organisation intends to manage and monitor regulatory, legal, risk, environmental, and operational demands vis-a-vis cybersecurity. Tools like CIS CSC 19, COBIT 5, ISA 62443-2-1:2009, ISO/IEC 27001:2013, and NIST SP 800-53 Rev. 4 provide invaluable frameworks for ensuring a well-rounded policy.

The emphasis here is not just on creating a policy but ensuring it's disseminated across the organisation. An informed team is a secure team.

2. Aligning Cybersecurity Roles (ID.GV-2) 🎭

Cybersecurity isn’t a siloed responsibility but a shared endeavour. A clear delineation of roles and responsibilities, both internally and with external partners, is vital for a cohesive cybersecurity strategy. Utilising frameworks like COBIT 5 and ISO/IEC 27001:2013 can help in structuring these roles effectively.

Communication is key. Ensuring everyone understands their role and the overall cybersecurity strategy significantly bolsters the organisation's security posture.

3. Understanding Legal and Regulatory Obligations (ID.GV-3) ⚖️

The legal landscape surrounding cybersecurity is ever-evolving. It's crucial for organisations to stay abreast of legal and regulatory requirements, including those concerning privacy and civil liberties. Tools like CIS CSC 19 and ISO/IEC 27001:2013 can aid in understanding and managing these obligations.

Adherence to legal and regulatory mandates not only fosters compliance but also cultivates trust with stakeholders.

4. Addressing Cybersecurity Risks in Governance and Risk Management Processes (ID.GV-4) 🎯

Incorporating cybersecurity risks into the broader governance and risk management processes is imperative. It's not about if a cybersecurity incident will occur, but when. Resources like COBIT 5, ISA 62443-2-1:2009, and ISO/IEC 27001:2013 provide detailed guidance on integrating cybersecurity risks within governance structures.

In conclusion, good governance is at the heart of effective cybersecurity. Through a well-structured policy, clear role delineation, understanding legal obligations, and integrating cybersecurity into risk management, organisations are better poised to navigate the complex cybersecurity landscape. The NIST CSF IDENTIFY domain offers a robust foundation for building and enhancing an organisation’s cybersecurity governance, ensuring it is well-equipped to tackle the challenges that lie ahead.
