Parameter based data access on a security information sharing platform

Example implementations relate to a security information sharing platform that enables sharing of security information among a plurality of members. For example, in an implementation, a system may determine that a first member of a community of a security information sharing platform is entitled access to a first set of encrypted information shared by a second member of the community. The system may also receive a request, from the first member, to access the first set of encrypted information, the request including a masked parameter. The system may also determine that the masked parameter matches an access parameter for accessing the first set of encrypted information and provide the first member access to the first set of encrypted information in response to determining that the masked parameter matches the access parameter.
