Many places were still referencing the old Suricata page.
Used git grep with replace to update them. Checked that new links work.
Left old references when they were only documentation examples (for
output or unittests).
Task#4915
The differences on how the `need` key works, depending on script
usage (output or detection) confuses users, sometimes (cf doc#4725).
While we don't fix that, just explain this behavior.
Renaming was done with shell commands, git mv for moving the files and content like
find -iname '*.c' | xargs sed -i 's/ikev1/ike/g' respecting the different mixes of upper/lower case.
Fixes https://redmine.openinfosecfoundation.org/issues/2689
Adds a new source file to handle this keyword.
And modifies documentation, Makefile, and registration accordingly.
url_decode decodes url-encoded data, ie replacing '+' with space
and '%HH' with its value.
This commit improves the description of the `tos` keyword by emphasizing
that the value used should adhere to the guidelines in RFC2474. Instead
of specifying the DSCP value directly, right shift the DSCP value and
use that.
This commit adds support for the Remote Framebuffer Protocol (RFB) as
used, for example, by various VNC implementations. It targets the
official versions 3.3, 3.7 and 3.8 of the protocol and provides logging
for the RFB handshake communication for now. Logged events include
endpoint versions, details of the security (i.e. authentication)
exchange as well as metadata about the image transfer parameters.
Detection is enabled using keywords for:
- rfb.name: Session name as sticky buffer
- rfb.sectype: Security type, e.g. VNC-style challenge-response
- rfb.secresult: Result of the security exchange, e.g. OK, FAIL, ...
The latter could be used, for example, to detect brute-force attempts
on open VNC servers, while the name could be used to map unwanted VNC
sessions to the desktop owners or machines.
We also ship example EVE-JSON output and keyword docs as part of the
Sphinx source for Suricata's RTD documentation.
