A method for executing a security stack can include executing a bootloader included in a memory resource of an electronic device in response to the bootloader receiving a prompt. The method can include performing a verification function, with the bootloader, on data stored in a programmable memory included in the memory resource of the electronic device, wherein the verification function includes comparing security data stored in a configuration area of the memory resource with a signature that accompanies the data stored in the programmable memory. The method can include determining whether the security data stored in the configuration area matches the signature that accompanies the data stored in the programmable memory.
