Don’t Leave IBM i Security to Chance: Why Independent Security Audits Are Critical
18 January 2025
In today’s digital landscape, cyber threats are more prevalent than ever, and businesses relying on IBM i (iSeries, OS400) technology cannot afford to overlook security. With the increasing sophistication of cybercriminals, securing your IBM i infrastructure and application software has become a non-negotiable priority.
The Risks of Neglecting IBM i Infrastructure Security
IBM i systems are known for their reliability, but like any technology, they require diligent upkeep to remain secure. Failing to update firmware, microcode, security patches, and operating systems can leave critical vulnerabilities open for exploitation. These gaps expose businesses to risks such as data breaches, ransomware attacks, and operational downtime.
To protect your infrastructure, businesses should:
- Keep firmware and microcode updated to the latest versions.
- Apply all available patches and security updates.
- Regularly review system configurations and access permissions.
- Ensure security policies are enforced for both on-premise and cloud-hosted environments.
Beyond Infrastructure: Securing Your Applications on IBM i
While infrastructure security is essential, application software running on IBM i also requires rigorous oversight. Vulnerable applications can serve as backdoors for cybercriminals, even if the underlying infrastructure is secure.
Key practices for application security include:
- Static Application Security Testing (SAST): Analyse your code for vulnerabilities and ensure compliance with security best practices.
- Code Reviews and Penetration Testing: Proactively identify and address potential weaknesses in application logic.
- Access Controls: Implement strict user access policies to minimise risks.
The Case for Independent Security Audits
Relying solely on in-house teams or managed service providers (MSPs) to review security is akin to a student marking their own homework. While operational staff or MSPs may handle day-to-day maintenance, they often lack the perspective needed for a thorough, unbiased evaluation. High staff turnover and competing priorities can lead to security gaps being overlooked or deprioritised.
This is where independent security experts come in. Technical Security Consultants:
- Work collaboratively with your in-house IBM technical team or MSP.
- Conduct thorough infrastructure and application audits.
- Provide actionable insights to strengthen your security posture without assigning blame.
By engaging an independent expert, you gain a fresh perspective that uncovers risks your team may not see.
Cyber Insurance: Prevention and Compliance
Many organisations invest in cyber insurance to protect against the financial fallout of an attack. However, these policies often require businesses to demonstrate that they’ve taken “reasonable steps” to mitigate risks. Without robust security policies and audits, your insurance claim could be denied.
Consider the cautionary tale of KNP Logistics Group, trading as Knights of Old. In September 2023, a cyber attack forced the logistics giant into administration, leading to over 700 job losses. The business’s insurance didn’t cover the damages due to critical security gaps. Such cases highlight the devastating impact of inadequate cybersecurity measures.
Annual independent audits are an essential step in meeting insurance requirements, protecting your business, and mitigating risks.
