- Description:
- Zeek (formerly known as Bro) is an open-source, Unix-based Network
Intrusion Detection System (NIDS) that passively monitors network
traffic and looks for suspicious activity. Zeek detects intrusions
by first parsing network traffic to extract its application-level
semantics and then executing event-oriented analyzers that compare
the activity with patterns deemed troublesome. Its analysis includes
detection of specific attacks (including those defined by signatures,
but also those defined in terms of events) and unusual activities
(e.g., certain hosts connecting to certain services, or patterns
of failed connection attempts).
Zeek is documented in the USENIX 1998 Security Conference proceedings
(as Bro).

LBL_CF=on: Unix time to formated time/date filter support
LBL_HF=on: Address to hostname filter support
NETMAP=on: Native Netmap Packet IOSource for Zeek
PERFTOOLS=off: Use Perftools to improve memory & CPU usage
SPICY=on: Enable the Spicy parser generator
ZEEKCTL=on: ZeekControl support (implies IPSUMDUMP)

- Options name:
- security_zeek
- USES:
- bison cmake compiler:c++17-lang cpe gettext-runtime perl5 python shebangfix ssl
- pkg-message:
- For install:
- The rc.d script now honors the zeek_user rc.d variable. To run as
a user other than root (the default) you need to make a few changes.
For example to run as the user zeek, add this to /etc/rc.conf:
zeek_enable="YES"
zeek_user="zeek"
Add this to /etc/devfs.conf:
own bpf root:bpf
perm bpf 0660
And add zeek to the bpf group:
bpf:*:81:zeek
and restart the devfs service:
service devfs restart
or reboot.
If the interface defined in node.cfg is configured for NIC checksum
offloading (the default when this feature is supported by the
hardware) you will want to set ignore_checksums in site/local.zeek:
redef ignore_checksums = T;
- If removing:
- During deinstall of this package, the cfg files for zeekctl are not
deleted if you have edited them. Instead the software will create
a .sample file and the edited files will remain in place when you
upgrade. If you want to delete them, you have to remove the
/usr/local/etc directory manually.
You may also need to manually remove /usr/local/spool/state.db
