What does Cisco LINA stand for? What is Cisco LINA?

Both really good questions….

LINA

The Cisco ASA uses a single monolithic binary (ELF) running directly on the main CPU and the ASA firmware is a Linux operating system running a single ELF called LINA. ┬áThe older PIX devices ran on a custom OS called PIX OS and had a similar binary running on them. The term “Lina” probably came from the name of someones kid or pet hamster, and is used to describe this ELF.

Why is this important? Because Cisco is using this term again to describe the code used before and after the SNORT process in the new Cisco FTD devices, as shown in the diagram.

However, I am not sure the name Lina generated by a furry pet has much relevance, and no one can find out the meaning of the true term, so this is a good answer for now.
