It's a fun class; worth keeping in mind that several topics with 1-2 units here are whole specializations in the field, including:

* memory safety and exploitation (the "buffer overflow" section is about 20 years out of date, though super appropriate for a first course)

* the WebPKI/certificates thing

* messaging security and messaging cryptosystems,

* microarchitectural security and hardware side channels.

Multiple full courses on each of these subjects would bring you up to "practitioner" levels of expertise.
