This article is about what is and isn't stored encrypted on disk for ZFS datasets that are encrypted and how we do the actual encryption. It does require some understanding of Solaris and ZFS debugging tools.

aurora.apache.org runs Solaris 10, and we were able to restore the box to a known-good configuration by cloning and promoting a ZFS snapshot from a day before the CGI scripts were synced over. Doing so enabled us to bring the EU server back online, and to rapidly restore our main websites. Thereafter, we continued to analyze the cause of the breach, the method of access, and which, if any, other machines had been compromised.

Nonetheless, Sun revealed Aug. 19 that it has become the first enterprise tape drive maker to be granted a prestigious federal security qualification: the FIPS 140-2 Certification at Security Level 2 for its Sun StorageTek T10000B tape drive.

Security Level 2 improves upon the physical security mechanisms of a Security Level 1 cryptographic module by requiring features that show evidence of tampering, including tamper-evident coatings or seals that must be broken to attain physical access to the plaintext cryptographic keys and critical security parameters (CSPs) within the module, or pick-resistant locks on covers or doors to protect against unauthorized physical access.

We assessed the accuracy of cutaneous infrared thermometry, which measures temperature on the forehead, for detecting patients with fever in patients admitted to an emergency department. Although negative predictive value was excellent (0.99), positive predictive value was low (0.10). Therefore, we question mass detection of febrile patients by using this method.
