AWS IAM
-------
- identity and access
- grant entities (services or humans) permission to make API calls on behalf of you or your account
- every AWS service uses IAM to authenticate and authorize API calls

## Here is an example nanorc for syntax highlighting in Zeek scripts. Edited the standard sh.nanorc to create this, and added in the regex described by Scott Runnels.
## For Scott's bro-mode.el, go to https://github.com/srunnels/bro-mode/blob/master/bro-mode.el

syntax "zeek" "\.zeek$"
magic "(POSIX|Bourne.*) shell script text"
header "^#!.*/(ba|k|pdk)?sh[-0-9_]*"
icolor brightgreen "^[0-9A-Z_]+\(\)"

color cyan "(usec|msec|sec|min|hr|day)s?\b"
color cyan "[0-9]+\/(tcp|udp|icmp|unknown)"
