Proactive Solutions to Enhance IBM i Cloud Security

IBM i cloud security

IBM i systems are known for their reliability and robust security features, like object-level security, comprehensive auditing, and advanced encryption. Although most cloud journeys start out in search of economic efficiencies, enhanced security quickly becomes the primary reason why IBM i organizations choose to migrate to the cloud. So, it’s crucial to identify and remediate IBM i cloud security challenges early (and often) to realize the benefits of improved security operations for your IBM i environment in the cloud. 

A Cloud Computing Recap 

Before we dive into specific security issues, let’s quickly recap what cloud computing is. Essentially, cloud computing refers to the consumption of services—like compute, storage, software applications, and other solutions—through a secure (or sometimes not so secure) network. Instead of on-site physical servers and hardware, those resources are accessed remotely. 

There are three main types of cloud computing: public, private, and hybrid. Public clouds are run by third-party providers and offer resources to multiple customers via shared or dedicated networks. Private clouds are managed by your organization, which gives you more control over resources. Hybrid clouds mix both public and private clouds and provide greater flexibility and optimized workload management. 

IBM i Cloud Security Considerations 

When you migrate IBM i workloads to the cloud, it’s essential to keep IBM i cloud security top of mind. For example, access and communication between your on-premises network must be secure. To start, you need to establish secure connectivity through an IPSEC (VPN) tunnel or software-defined wide area network (SD-WAN), but it’s equally important to configure and audit strict firewall rules and port configurations to prevent unauthorized access and ensure secure data exchanges. 

On August 15, I’ll tackle the bigger picture of IBM i cloud strategy in our webinar, “Elevate Your IBM i Cloud Strategy,” but in the meantime here are some tips to keep your cloud workloads secure: 

Build a Security-First Culture 

To navigate the complexities of IBM i cloud security, I recommend a strong culture of security throughout the organization. Every team member, not just the IT department, should be aware of potential threats and security protocols. 

Regular audits and disciplined user access management are fundamental. Review user profiles and ensure best practices in data access are followed. When you focus on the human element and actively discourage complacency in security measures, you further minimize risks in your operations. 

Security training and awareness programs for employees should be mandatory. These programs should cover the latest cybersecurity threats, safe online practices, and the importance of strong passwords. Simulated phishing exercises will also reinforce learning and highlight the risks of social engineering attacks. This not only enhances employee awareness but also improves the overall security culture within the organization. Repetition and accountability reinforce the messages. 

When you equip employees with the knowledge and tools to recognize and respond to potential security threats, you create a more vigilant workforce. 

Proactive Threat Assessment and Mitigation 

A methodical approach is essential to effectively assess and mitigate security risks in your cloud environments. Start with regular security scans and other system audits and ensure strict adherence to established security policies. Of course, mitigate any identified risks as soon as possible. It’s also crucial to develop a robust reporting mechanism for security incidents, coupled with a comprehensive incident response strategy to manage any events that arise.

Implement Effective Data Security Measures 

To protect sensitive data on IBM i systems, embrace a layered approach to data protection. Responsibilities for safeguarding data should be clearly delineated among all stakeholders. Enforce least privileged access policies to reduce the risk of unauthorized data access and establish a plan to migrate to a zero-trust architecture. 

Encryption is vital for data protection because it safeguards information both at rest and in transit. Encryption should be implemented (or at least evaluated) at every layer of a cloud architecture – from network to hardware to databases and applications. Of course, employ robust password management practices to maintain the integrity and confidentiality of critical data. And don’t write them down and tape them to the laptop screen. 

Multi-factor authentication (MFA) is one of the most effective ways to enhance security in IBM i cloud environments. MFA requires users to provide two or more verification factors to gain access, which significantly reduces the risk of unauthorized access even if a password is compromised. 

Ensure MFA is enabled for all critical systems and applications, especially those that handle sensitive data. 

Compliance and Standardization 

It’s essential to adhere to industry regulations and standards when you embark on your IBM i cloud journey. Your cloud provider should have these controls in place, so review their third-party certifications like ISO27001 and SOC 2 to ensure they demonstrate effective security controls and policies. Also, evaluate your organization’s compliance requirements as might be needed for to conduct business in different geographies. Standards such as PIPEDA for Canada, GDPR for European entities and newly emerging state-specific regulations in the U.S should be included in the evaluation. 

Evaluate. Improve. Test. 

A security policy that is buried in a mountain of e-mail or on a shared file store is the same as no policy. Policies should be reviewed quarterly to identify and document opportunities for improvement. But testing is the gold standard and including your cloud provider as a participant should be a core part of that effort. Start with a tabletop exercise and grow from there. 

Availability and security are equivalents, so include a disaster recovery policy, plan, and a fully functional test as part of your IBM i cloud model as a best practice.  

Leverage Advanced Technology for Enhanced IBM i Cloud Security 

Emerging technologies like artificial intelligence (AI) and machine learning can significantly enhance IBM i cloud security. AI can detect and remediate security threats, which improves an organization’s responsiveness and adaptability to evolving threats. As cyber threats have become more complex and persistent, and data volumes have expanded logarithmically, automation and AI tools have become indispensable to secure your environment.  Leverage a cloud provider’s capabilities to correlate events observed on your IBM i platform with the endless catalog of security events that take place beyond its boundaries – this is a great example of the value of a shared service.  

It’s paramount for IT professionals who manage IBM i workload in the cloud to understand how to navigate the landscape of security challenges. When you prioritize a culture of security and implement robust data protection measures, you can effectively manage security regardless of where your applications are hosted. With the right strategies in place, businesses can enjoy the benefits of cloud computing while they protect their most vital assets.  

In this ever-evolving digital landscape, strong IBM i cloud security is not just a necessity; it’s the foundation of sustainability and trust for any organization. You need ongoing commitment and investment to achieve these goals, but the rewards—both in terms of operational resilience and stakeholder confidence—are well worth it. 

You don’t have to tackle IBM i cloud security alone. Fresche’s security suite offers comprehensive IBM i security, auditing, and intrusion detection to protect your applications, while our Fresche Cloud adheres to all recommended security protocols.
