BMC Compuware Application Audit
BMC Software
BMC Compuware Application Audit enables security and compliance teams to easily capture start-to-finish mainframe user behavior in real time, including all successful logins, session keyboard commands and menu selections, and specific data viewed without making any changes to mainframe applications. Application Audit enables enterprises to capture all relevant data about user access and behavior on the mainframe to mitigate cybersecurity risks and fulfill compliance mandates. Get deep insight into user behavior including data viewed, by whom, and which applications were used to access it. Deliver the granular intelligence and reporting needed to comply with regulations such as HIPAA, GDPR, the Australian NDB scheme, as well as company security policies. Separate the system administrator’s duties from the responsibilities of auditors with a web UI, so that no single person is in a position to engage in malicious activities without detection. -

Integrate mainframe and IBM i systems into leading IT analytics and operations platforms for an enterprise-wide view to support your digital business. In today’s digital, always-on world, IT is arguably the most important department across your organization. A single security breach or service outage can bring your business to a standstill. But knowing what’s happening across an increasingly complex landscape of infrastructure and apps, and resolving issues before they impact the business, is a daunting task. The good news is that there are several platforms to help you monitor IT security and operations across the enterprise in real-time, and take action fast. The challenge, however, is that mainframe or IBM i systems aren’t natively supported by these modern tools. So, if you rely on these critical servers to run your business and you’re managing them in isolation, you have a dangerous blind spot. -

IBM RACF for z/OS enables the protection of your mainframe resources by making access control decisions through resource managers. Granting access to only authorized users keeps your data safe and secure. RACF authenticates users with a password, password phrase, digital certificate, Kerberos ticket, or a PassTicket. Protect your mainframe resources with tools that manage and control access to valuable z/OS data. RACF retains information about your users, resources, and access authorities in its database. This database determines access to protected mainframe system resources based on your security policy. RACF has logging and reporting functions that identify users who attempt to access the resource, either successfully or unsuccessfully. Detection of security exposures or threats is made possible by this feature. Through the RRSF, you have the capability to run most RACF commands on a node and a user ID different from the one you are logged on to.

Mainframe systems are the foundation of trusted digital experiences for most of the world’s largest companies and organizations. However, passwords protecting critical users, data, and applications are a relatively simple point of attack for hackers to exploit because the passwords rely on user education and compliance for both implementation and control. By using a variety of methods, such as social engineering and phishing, criminals have exploited employees, partners, and general users to hack into even the most secure platforms. IBM Z MFA raises the level of assurance of your mission-critical systems with expanded authentication capabilities and options for a comprehensive, user-centered strategy that helps mitigate the risk of compromised passwords and system hacks. Our designers are also IBM Z MFA users. Across every new version, we incorporate their growing knowledge and expertise in real-world mainframe security scenarios.
