- 8. System values settings 8 • The QSECURITY system value is used to specify the security level of the OS • Must be set to 40 or 50. • Activates system-integrity protection for your IBM i • Object-domain checking • Parameter validation • Object-hardware storage protection • Prevent direct access to objects • Ensures user-written programs utilize system interfaces (commands and APIs) in order to gain access to objects • Decide whether to enable QALWOBJRST, QFRCCVNRST, QVFYOBJRST, and other system values related to integrity and security.
- 10. IBM i server-configuration settings 10 • Numerous servers on IBM i allow a client system to connect over a network • FTP • TELNET • ODBC • JDBC • DRDA • Sign-on server, and many others • Starting all servers by default on an IBM i unnecessarily opens “doors” into the system, • Review all IBM i servers • Deactivate any that aren’t needed.
- 11. System Services Tools (SST) settings
- 12. System Services Tools (SST) settings 12 • Many SST capabilities provide significant access to data • Network trace tools can provide a view of data flowing over a network • Manage or view storage dumps • Manage other service tools User IDs • Limit number of users having SST access
- 14. User authority settings 14 • Many companies have too many users with powerful profiles • *SECADM authority • *ALLOBJ authority • Command-line access • Stop the spread of powerful profiles • Assign limited privileges to the majority of user profiles • Temporarily grant selected users the authority they need to do a task • Utilize third-party solutions • Make it easier for administrators, security officers, and end users to temporarily obtain elevated privileges as required. • Log all actions taken once a user has the temporarily elevated authority
- 15. Staying current on OS releases and PTFs
- 16. Staying current on OS releases and PTFs 16 • Running older releases of the IBM i OS can open a security risk within an enterprise. • Risk from open-source packages that are no longer supported by the open-source community but that run on systems with older IBM i OS release levels. • Java • OpenSSL/SSH • Samba • Lotus products • Web and application servers • Subscribe to IBM’s security bulletins and tech notes for IBM i
- 17. Top Takeaways • For QSECURITY system value, you should be at security level 40 or 50 • Deactivate any IBM i servers not in use • Take care with access to System Service Tool capabilities • Limit Powerful Profiles on your system • Stay up-to-date with IBM i OS PTFs 17

Editor's Notes
- Amy: You need to use data to secure your data
- The increased frequency of high-profile breaches and the corresponding rise of new and expanded regulatory compliance requirements is putting enormous pressure on IT departments to assure their corporate executives that business-critical systems and data are secure. One particular statistic from a recently conducted Precisely survey of IT professionals is revealing in that 69% of respondents said they were only “somewhat confident” (or worse) in the effectiveness of their company’s IT security program. Given today’s rapidly evolving security threats, even being “somewhat confident” doesn’t cut it. Improving confidence in one’s IT security posture requires a solid understanding of all potential vulnerabilities as well as the most effective best practices and technologies in order to minimize the possibility of a breach. To help, Precisely has created this white paper as a roadmap, grouping together important security best practices and technologies into six primary categories or “layers.” These layers cover physical devices, networks, configuration of the IBM i OS, access to systems, protection of data at the file and field level, and monitoring and auditing of systems. The reason it’s particularly helpful to view these security categories as “layers” is that, to some extent, each category overlaps with the others to provide multiple lines of defense. In other words, should one security layer be somehow compromised, there’s a good chance that another layer will thwart a would-be intruder. The six layers of IBM i security are summarized in the following diagram and are detailed in the remainder of this white paper
- QALWOBJRST – Allow object restore option QVFYOBJRST – Verify object on restore QFRCCVNRST - Force conversion on restore QVFYOBJRST=3, QFRCCVNRST=3, and QALWOBJRST=*ALWPTF or *NONE work together. WRKSYSVAL SYSVAL(*SEC) for the entire list Use the ANZDFTPWD command to check for default passwords Create the QAUDJRN audit journal - CHGSECAUD
- ENDTCPSVR ENDHOSTSVR NETSTAT – Option 3 or 4 to see Listening Ports 3rd party tools are available to monitor and secure
- DSPSSTUSR (Display Service Tool User CL command) Command line interface to “audit” service tool users and privileges STRSST (Start System Service Tools command) Command line interface to the System Service tool menu Create as few Service Tools User IDs (SST/DST) as possible Create a Service Tool user with the same privileges as QSECOFR (QSECOFR can become disabled) Never use QSECOFR Service Tool USERID (save the password in a secure location)
- *SECOFR Class User Profiles Audit powerful profiles with CHGUSRAUD command In OS 7.3, IBM added Authority Collection that can be used to determine what security a user needs
- DSPPTF/WRKPTF QAUDJRN now has *PTFOBJ – Changes to PTF objects and *PTFOPR – PTF Operations
