30.5 Preventing Exposure of Sensitive Data in a Core Dump

When a core dump occurs for an encrypted NSS volume, data from the encrypted volume might be included in the core dump as unencrypted data dumped from cache memory. To prevent encrypted data exposure in the dump, select to exclude cache during a core dump when prompted to select writing all of memory in the core dump or to exclude NSS cache.

This applies also for volumes that are not encrypted but contain confidential data. Although the data is not normally encrypted, you might not want to allow unauthenticated access to the information.
