Post by Jan 25, 2024 4:06:34 PM · 3 min read

For decades, IBM Power i has been synonymous with reliable, secure business operations. Its robust architecture and bulletproof software have protected sensitive data and powered mission-critical applications for countless organizations. Now, with the rise of cloud computing, Power i is experiencing a renaissance, migrating its strengths to the agility and scalability of the cloud. But how does Power i's renowned security translate to the cloud environment? The answer lies in a powerful combination of inherent security features, cloud-specific enhancements, and best practices for managing your Power i cloud deployment. 

Here are the top 6 things you need to know about Power i security in the cloud: 

  1. Inherent Security Baked into the System:

Power i's security isn't bolted on; it's woven into the core. Multi-level security starts at the hardware level with features like tamper-resistant processors and secure cryptographic engines. The operating system, IBM i, adds sophisticated layers of protection, including user roles and permissions, granular access controls, and built-in encryption for data at rest and in transit. This robust foundation gives you a secure starting point in the cloud, minimizing your attack surface and providing a solid base for further security measures. 

  1. Shared Responsibility Model:

Moving to the cloud doesn't mean your security responsibilities disappear. It's a shared responsibility between you and your cloud provider. Your provider secures the underlying infrastructure, while you're responsible for securing your data and applications. This approach leverages the expertise of your cloud provider for infrastructure security while giving you control over your specific business information. Familiarize yourself with your provider's security commitments and ensure you have the tools and expertise to manage your own security posture effectively. 

  1. Cloud-Enhanced Security Features:

Cloud providers like IBM Cloud offer built-in security features specifically designed for Power i deployments. These features can enhance your existing security posture with tools like vulnerability scanning, intrusion detection, and threat intelligence. Additionally, many providers offer managed security services tailored for Power i, taking a proactive approach to threat detection and incident response. Explore these cloud-specific offerings and find the right combination to build a comprehensive security strategy for your Power i environment. 

  1. Encryption - Your Data's Force Field:

Encryption is a crucial line of defense for protecting sensitive data. Power i offers robust encryption capabilities, allowing you to encrypt data at rest in storage and in transit over the network. Make sure you leverage these features effectively, identifying and classifying your most sensitive data and applying appropriate encryption levels. Remember, encryption is like a force field for your data – the stronger the encryption, the tougher it is for attackers to breach. 

  1. Identity and Access Management (IAM) - Controlling Your Keys:

Just like a physical building needs strong locks and key control, your cloud environment needs robust IAM controls. Power i's built-in user roles and permissions are a good starting point, but consider implementing additional IAM solutions in the cloud. These solutions can provide multi-factor authentication, single sign-on, and fine-grained access controls, ensuring only authorized users access your data and applications. Treat your identity and access controls as the keys to your digital kingdom – safeguard them diligently. 

  1. Continuous Monitoring and Improvement:

Security is not a one-time event; it's an ongoing process. Continuously monitor your Power i cloud environment for suspicious activity, vulnerabilities, and potential threats. Log data, analyze security events, and update your security posture accordingly. Additionally, adopt a culture of security awareness within your organization, training employees on best practices and phishing awareness. Remember, security is a journey, not a destination – commit to continuous improvement and stay vigilant against emerging threats. 

By understanding these six key points, you can leverage the inherent security of Power i and the additional capabilities of the cloud to create a robust and secure environment for your business-critical applications and data. Embrace the shared responsibility model, explore cloud-enhanced security features, and implement best practices for encryption, IAM, and continuous monitoring. With a proactive approach and the right tools, Power i can be a powerful engine for driving secure and agile business operations in the cloud. 

Remember, security is not just about technology; it's about building a culture of awareness and best practices. By combining Power i's inherent security strengths with the agility and flexibility of the cloud, you can unlock a future of secure and innovative business possibilities.
