IronSphere for z/OS by Software Diversified Services provides automated DISA STIG compliance monitoring and real-time, continuous mainframe security monitoring and auditing. It strengthens mainframe security and assists in complying with U.S. Federal Government standards. IronSphere for z/OS is developed by mainframe penetration testers and security experts, adhering to security compliance mandates and guidelines essential for specific sectors. It automatically runs security diagnostic scans based on DISA STIGs, which is a DoD requirement. This tool also helps comply with additional standards by following NIST ISCM guidelines, NIST CSF, and RMF. IronSphere for z/OS automatically identifies system risks and provides remediation steps as part of the assessment results. Results are stored within the tool, demonstrating continuous monitoring of your z/OS system and compliance with ISCM and RMF protocols. It enhances system visibility by displaying z/OS scan results and vulnerabilities in a GUI for Security and GRC Teams, Upper-Level Managers, and the z/OS Mainframe Team. IronSphere for z/OS simplifies z/OS security compliance by automating STIGs. Many z/OS components lacking DISA STIGs have their own checks on the IronSphere system. Additional checks can be requested and configured quickly. New checks can be created by your team, tailored to fit your needs, and implemented within the product. IronSphere for z/OS helps achieve compliance with NIST ISCM, FISMA, GDPR, and others, using DISA STIGs and facilitating Risk Management Framework implementation on the mainframe. Its GUI allows users without mainframe expertise to view and understand system risks and necessary actions. IronSphere for z/OS identifies vulnerabilities and system issues through continuous monitoring, achieving a high level of z/OS security and smooth audits. It features an ISCM, RMF-based tool that continuously monitors the mainframe on an optimal schedule. Real-time z/OS monitoring helps protect data, achieve top-level security, and comply with standards. IronSphere for z/OS provides a single point of reporting for mainframe system health and risks. It saves resources via automatic delivery of DISA STIGs for required system software updates. The Lean agent efficiently gathers data on mainframes without leaving a trace. It offers a flexible solution to define user roles, create system checks/STIGs, and configure settings. It runs on various mainframe operating systems: z/OS, Linux on IBM Z, z/VSE, z/VM, z/TPF, AS/400. IronSphere for z/OS enhances security, avoids breaches, and ensures compliance for large organizations while helping smaller z/OS shops with best practices and cost reduction through automation.
