Running a tech-dependent business? Time to get your ITGC game on! These controls are like the superhero policies that ensure your systems are on lockdown, protecting your data’s confidentiality, integrity, and availability. They’ll save you from unauthorized access, breaches, and operational roadblocks. Plus, they’ll keep you compliant with SOX, HIPAA, PCI DSS, and more!

In this blog post, we will explain what ITGC are, why they are important, and how you can implement them effectively. We will also share some best practices and tips to help you maintain strong ITGC and avoid common pitfalls.

What are IT General Controls (ITGC)?

ITGC, or IT general controls, are a set of directives that determine how a business’s systems operate. They prevent data theft, unauthorized access, operational disruption, and data breaches. They influence every aspect of IT, from setting up new software to user account creation. ITGC also impacts vendor management, as new applications and procurement must also meet the standards set by the controls. Having ITGC in place ensures that your systems are protected, tested, and implemented correctly, and security and network updates happen at the right times.

ITGC are not the same as application controls. Application controls restrict what users can do within one particular platform, and typically these permissions are configured directly within that application and pertain to specific features or use cases. ITGC govern the use of all systems within a company, from ERPs to servers, directory platforms, and project management tools.

Why are ITGC important?

ITGC are essential for any business that uses IT systems to store, process, or transmit data. Without ITGC, you are exposing your business to various risks, such as:

• Reputational risks: Your business reputation is built on trust between customers and shareholders. You can have severe reputational risks if your company lacks the right cybersecurity or physical security to keep your data centers secure. This can hurt your industry standing, which can ultimately cause you to lose revenue.
• Operational risks: ITGC also protect your business operations. If your systems are damaged by a cyberattack or a lack of compliance, it can slow down or halt your entire operation and put you at risk of even more damage.
• Financial risks: ITGC can also affect your financial performance and reporting. If your systems are compromised or inaccurate, you can face fines, penalties, lawsuits, or audits from regulators, customers, or investors. You can also lose money due to fraud, theft, or loss of data.
• Compliance risks: ITGC help you comply with various regulations that apply to your industry and location. For example, if you are in the financial services or healthcare sector, you need to follow SOX, HIPAA, or PCI DSS, which require you to have ITGC in place. Failing to comply can result in legal actions, sanctions, or loss of licenses.

By implementing ITGC, you can reduce these risks and protect your business from cyber threats and noncompliance. You can also improve the reliability and accuracy of your financial reporting and reduce the risk of fraud. Moreover, you can enhance your customer satisfaction and loyalty by safeguarding their information and providing them with uninterrupted service.

How to implement ITGC effectively?

ITGC can take on many forms, but most fall under a few distinct categories. Let’s review each in detail.

Access Controls

Access controls define who can see and use what data and systems. They reduce the risk of data breaches and unauthorized data manipulation by preventing unauthorized access. Effective access controls include:

• Biometric authentication: This involves using physical characteristics such as fingerprints, facial recognition, or iris scans to verify a user’s identity. This is more secure than passwords or PINs, which can be stolen or guessed.
• Multi-factor authentication: This requires users to provide more than one piece of evidence to prove their identity, such as a password and a code sent to their phone or email. This adds an extra layer of security and prevents hackers from accessing accounts with stolen credentials.
• Role-based access control: This assigns users different levels of access based on their roles and responsibilities within the organization. For example, an accountant may have access to financial data, but not to customer data. This limits the exposure of sensitive data and reduces the risk of insider threats.
• Least-privilege access policy: This grants users the minimum amount of access they need to perform their tasks, and nothing more. This reduces the attack surface and minimizes the damage that can be done by a compromised account.

System Development and Change Management Controls

System development and change management controls ensure that the IT systems are designed, developed, tested, and implemented correctly and securely. They also ensure that any changes or updates to the systems are authorized, documented, and monitored. Effective system development and change management controls include:

• System development life cycle (SDLC) controls: These are the steps and processes that guide the creation and maintenance of IT systems, from planning and analysis to design, development, testing, deployment, and evaluation. SDLC controls ensure that the systems meet the business requirements and objectives, and that they are secure, reliable, and scalable.
• Program change management controls: These are the procedures and tools that manage the changes or updates to the IT systems, such as bug fixes, enhancements, or patches. Program change management controls ensure that the changes are approved, tested, and tracked, and that they do not introduce new errors or vulnerabilities.
• Segregation of duties: This involves separating the roles and responsibilities of different individuals or teams involved in the system development and change management process. For example, the developers who write the code should not be the same as the testers who verify the code, or the approvers who authorize the code. This prevents conflicts of interest, fraud, or errors.

Backup and Recovery Controls

Backup and recovery controls ensure that the IT systems and data are backed up regularly and can be restored in case of a disaster or an incident. They also ensure that the backups are secure, complete, and accessible. Effective backup and recovery controls include:

• Backup policy: This defines the frequency, scope, and method of backing up the IT systems and data. For example, a backup policy may specify that the systems and data are backed up daily, weekly, or monthly, and that they are stored on-site, off-site, or in the cloud. A backup policy also defines the roles and responsibilities of the backup team, and the tools and procedures they use.
• Backup testing: This involves verifying that the backups are working properly and can be restored in case of a need. Backup testing should be done periodically and after any major changes to the systems or data. Backup testing also involves checking the integrity, security, and availability of the backups.
• Disaster recovery plan: This is a document that outlines the steps and actions to take in the event of a disaster or an incident that affects the IT systems and data. A disaster recovery plan specifies the roles and responsibilities of the recovery team, the resources and tools they need, and the recovery objectives and timelines. A disaster recovery plan also includes the scenarios and procedures for different types of disasters, such as fire, flood, power outage, cyberattack, or human error.

Computer Operation Controls

Computer operation controls ensure that the IT systems are running smoothly and efficiently, and that they are monitored and maintained regularly. They also ensure that the IT systems are secure and compliant with the relevant standards and regulations. Effective computer operation controls include:

• Performance monitoring: This involves measuring and analyzing the performance and availability of the IT systems, such as the CPU, memory, disk, network, and application usage. Performance monitoring helps identify and resolve any issues or bottlenecks that may affect the system functionality or user experience.
• Security monitoring: This involves detecting and responding to any security incidents or threats that may compromise the IT systems or data, such as malware, phishing, denial-of-service, or unauthorized access. Security monitoring helps prevent or mitigate the impact of cyberattacks and data breaches.
• Log management: This involves collecting, storing, and analyzing the logs generated by the IT systems, such as the system events, user activities, errors, or transactions. Log management helps track and audit the system behavior and performance, and identify any anomalies or violations.
• Patch management: This involves applying the latest updates or fixes to the IT systems, such as the operating system, applications, or firmware. Patch management helps improve the system functionality and security, and protect the systems from known vulnerabilities or exploits.

How to maintain strong ITGC: 3 crucial steps

Implementing ITGC is not a one-time project, but an ongoing process that requires constant attention and improvement. Here are three crucial steps to help you maintain strong ITGC and avoid common pitfalls.

Step 1: Conduct regular ITGC audits

An ITGC audit is a systematic examination of your ITGC to verify their effectiveness and compliance. An ITGC audit can be done internally by your own IT team, or externally by a third-party auditor. An ITGC audit can help you:

• Assess the adequacy and efficiency of your ITGC
• Identify and address any gaps or weaknesses in your ITGC
• Ensure that your ITGC comply with the relevant regulations and standards
• Provide assurance and evidence to your stakeholders, customers, and regulators

An ITGC audit should cover all the categories and components of your ITGC, and follow a consistent and documented process. An ITGC audit should also include testing and sampling of your ITGC, such as reviewing the policies and procedures, interviewing the staff, inspecting the systems and data, and observing the operations.

Step 2: Implement corrective actions and improvements

Based on the findings and recommendations of your ITGC audit, you should implement the corrective actions and improvements to address the issues and enhance your ITGC. You should also document the actions taken, the results achieved, and the lessons learned. Some examples of corrective actions and improvements are:

Updating or revising your ITGC policies and procedures Providing training or awareness programs to your IT staff and users Implementing new tools or technologies to improve your ITGC Strengthening your ITGC testing and monitoring processes Reporting and communicating your ITGC progress and performance You should also prioritize the corrective actions and improvements based on the severity and urgency of the issues, and allocate the necessary resources and time to complete them. You should also track and measure the effectiveness and impact of the corrective actions and improvements, and ensure that they are aligned with your business goals and objectives.

Step 3: Establish a continuous improvement cycle

To maintain strong ITGC, you need to establish a continuous improvement cycle that involves regularly reviewing, evaluating, and improving your ITGC. A continuous improvement cycle can help you:

Adapt to the changing IT environment and business needs Incorporate the latest IT best practices and standards Identify and prevent new or emerging IT risks and threats Enhance your IT performance and efficiency Increase your IT value and competitiveness A continuous improvement cycle consists of four phases: plan, do, check, and act. In the plan phase, you define your ITGC objectives, scope, and strategy, and identify the gaps and opportunities for improvement. In the do phase, you implement the corrective actions and improvements that you have planned. In the check phase, you monitor and evaluate the results and outcomes of your actions and improvements, and compare them with your expectations and benchmarks. In the act phase, you analyze and learn from your findings and feedback, and make the necessary adjustments and refinements to your ITGC.

Conclusion

ITGC are a vital part of any business that uses IT systems to store, process, or transmit data. They help you protect your data, systems, and operations from various risks, such as cyberattacks, data breaches, fraud, or noncompliance. They also help you improve your IT reliability, accuracy, and efficiency, and enhance your customer satisfaction and loyalty.

To implement and maintain strong ITGC, you need to follow a systematic and structured approach that covers all the aspects and components of your ITGC, such as access controls, system development and change management controls, backup and recovery controls, and computer operation controls. You also need to conduct regular ITGC audits, implement corrective actions and improvements, and establish a continuous improvement cycle.
