Which two formats are supported by whitelist?

The correct answer includes the CSV format because it is widely supported as a structured data representation that allows for easy input and manipulation. In the context of whitelisting, CSV files are commonly used to list allowed entries, such as IP addresses or domain names, due to their simplicity and broad compatibility with various software applications and systems. This structured format makes it straightforward for users to create and update lists of trusted entities.

While other formats such as Regex, STIX, and CIDR may serve useful purposes in different contexts, they are not primarily associated with whitelist implementations. Regex could potentially be used for pattern matching but is not a common format for whitelisting data. STIX is mainly used for sharing cyber threat intelligence and is more complex compared to the straightforward nature of CSV. CIDR, which stands for Classless Inter-Domain Routing, is essential for defining IP address ranges but does not serve as a standalone format for listing entities in a whitelist context like CSV does.
