Splunk Enterprise Certified Admin Practice Test

In the context of Whitelist and Blacklist, can wildcards be used effectively?

1. True

2. False

3. Only for Whitelist

4. Only for Blacklist

The correct answer is: False

Wildcards are not typically used effectively in the context of Whitelist and Blacklist configurations within Splunk. This means that when configuring these lists, the implementation generally relies on specifying exact matches or specific patterns rather than utilizing wildcards. The rationale behind this relies on the need for precision when allowing or denying access or inclusion of data. Wildcards can introduce ambiguity and create potential overlaps, which could lead to security vulnerabilities or unintended exclusions. As a result, effective use of Whitelist and Blacklist involves clear, unambiguous entries rather than flexible, wildcard-based patterns. In addition, the need for strict criteria in these lists helps ensure that only designated data is allowed while other data is filtered out, thereby maintaining the integrity and security of the system.
