System Integrity

Trust but verify

Share |

“Trust but verify” became one of the signature phrases of 1980s nuclear disarmament treaties. It asserts that while information from trusted sources should be considered reliable, additional checks are nevertheless always a good idea. The same phrase should also apply to systems that hold your most sensitive business and client data.

System integrity is a fundamental design point of IBM i. The phrase ”recompiling the kernel” doesn’t appear in its lexicon. In fact, IBM i hardware-enforced integrity ensures objects cannot be tampered with maliciously or inadvertently. The operating system is digitally signed and has tamper-proof auditing logs, role-based authority and built-in encryption options. The result? IBM i has a reputation for being among the most secure systems for helping businesses protect their most vital data and applications.
