[Update] Zeek — Security Onion 2.3 documentation | zeek – Vietnamnhanvan

zeek: นี่คือโพสต์ที่เกี่ยวข้องกับหัวข้อนี้

Zeek is formerly known as Bro. From https://www.zeek.org/:

Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. (Zeek is the new name for the long-established Bro system. Note that parts of the system retain the “Bro” name, and it also often appears in the documentation and distributions.)

Zeek logs are sent to Elasticsearch for parsing and storage and can then be found in Hunt and Kibana. Here’s an example of Zeek conn (connection) logs in Hunt:

Community ID

Security Onion enables Zeek’s native support for Community ID.

Performance

Zeek uses AF-PACKET so that you can spin up multiple Zeek workers to handle more traffic.

To change the number of AF-PACKET workers for Zeek:

  • Stop Zeek:

    sudo

    so

    -

    zeek

    -

    stop

  • Edit /opt/so/saltstack/local/pillar/minions/$SENSORNAME_$ROLE.sls and change the zeek_lbprocs variable to the desired number of cores.

  • Start Zeek:

    sudo

    so

    -

    zeek

    -

    start

For best performance, Zeek should be pinned to specific CPUs. In most cases, you’ll want to pin sniffing processes to a CPU in the same Non-Uniform Memory Access (NUMA) domain that your sniffing NIC is bound to. Accessing a CPU in the same NUMA domain is faster than across a NUMA domain.

See also

For more information about determining NUMA domains using lscpu and lstopo, please see https://github.com/brokenscripts/cpu_pinning.

To pin Zeek workers to specific CPUs:

  • Stop sensor processes:

    sudo

    so

    -

    zeek

    -

    stop

  • Edit /opt/so/saltstack/local/pillar/minions/$SENSORNAME_$ROLE.sls and add the following under sensor:

    zeek_pins

    :

    -

    <

    cpu_1

    >

    -

    <

    cpu_2

    >

    -

    <

    cpu_3

    >

  • Note: To avoid inconsistent Zeek workers being allocated, ensure zeek_lbprocs is removed from under sensor: or is equivalent to the number of cpu cores being pinned.

  • Start sensor processes:

    sudo

    so

    -

    zeek

    -

    start

Syslog

To forward Zeek logs to an external syslog collector, please see the Syslog Output section.

Intel

You can add your own intel to /opt/so/saltstack/local/salt/zeek/policy/intel/intel.dat on the manager and it will automatically replicate to all forward nodes. If the /opt/so/saltstack/local/salt/zeek/policy/intel/ directory is empty, you can copy the default files (both intel.dat and __load__.zeek) from /opt/so/saltstack/default/salt/zeek/policy/intel/ as follows:

sudo

cp

/

opt

/

so

/

saltstack

/

default

/

salt

/

zeek

/

policy

/

intel

/*

/

opt

/

so

/

saltstack

/

local

/

salt

/

zeek

/

policy

/

intel

/

Please note that Zeek is very strict about the format of intel.dat. When editing this file, please follow these guidelines:

  • no leading spaces or lines
  • separate fields with a single literal tab character
  • no trailing spaces or lines

The default intel.dat file follows these guidelines so you can reference it as an example of the proper format.

When finished editing intel.dat, run sudo salt $SENSORNAME_$ROLE state.highstate to sync /opt/so/saltstack/local/salt/zeek/policy/intel/ to /opt/so/conf/zeek/policy/intel/. If you have a distributed deployment with separate forward nodes, it may take up to 15 minutes for intel to sync to the forward nodes.

If you experience an error, or do not notice /nsm/zeek/logs/current/intel.log being generated, try having a look in /nsm/zeek/logs/current/reporter.log for clues. You may also want to restart Zeek after making changes by running sudo so-zeek-restart.

For more information, please see:

https://docs.zeek.org/en/latest/frameworks/intel.htmlhttp://blog.bro.org/2014/01/intelligence-data-and-bro_4980.htmlhttps://github.com/weslambert/securityonion-misp

Custom Scripts

Custom scripts can be added to /opt/so/saltstack/local/salt/zeek/policy/custom/<$custom-module> on the manager. The custom folder is mapped to Zeek through Docker on the minions. Once the script module is created, the configuration for local.zeek will need to be updated. In Security Onion 2, this configuration is abstracted into a SaltStack pillar. For example, we would copy /opt/so/saltstack/default/pillar/zeek/init.sls to /opt/so/saltstack/local/pillar/zeek/init.sls, and add our custom module to be loaded by Zeek (alternatively, the pillar could be modified in the global.sls file. More details can be found here here: https://docs.securityonion.net/en/latest/zeek.html#configuration):

zeek: local: '@load': - misc/loaded-scripts - tuning/defaults - misc/capture-loss - misc/stats - frameworks/software/vulnerable - frameworks/software/version-changes - protocols/ftp/software - protocols/smtp/software - protocols/ssh/software - protocols/http/software - protocols/dns/detect-external-names - protocols/ftp/detect - protocols/conn/known-hosts - protocols/conn/known-services - protocols/ssl/known-certs - protocols/ssl/validate-certs - protocols/ssl/log-hostcerts-only - protocols/ssh/geo-data - protocols/ssh/detect-bruteforcing - protocols/ssh/interesting-hostnames - protocols/http/detect-sqli - frameworks/files/hash-all-files - frameworks/files/detect-MHR - policy/frameworks/notice/extend-email/hostnames - ja3 - hassh - intel - cve-2020-0601 - securityonion/bpfconf - securityonion/communityid - securityonion/file-extraction - custom/$module-name

One the configuration has been updated, Zeek can be restarted with sudo so-zeek-restart on applicable nodes to pick up the changes. Finally, /nsm/zeek/logs/current/loaded_scripts.log can be checked to ensure the new module has been loaded. For example:

grep

mynewmodule

/

nsm

/

zeek

/

logs

/

current

/

loaded_scripts

.

log

Logs

Zeek logs are stored in /nsm/zeek/logs. They are collected by Filebeat, parsed by and stored in Elasticsearch, and viewable in Hunt and Kibana.

We configure Zeek to output logs in JSON format. If you need to parse those JSON logs from the command line, you can use jq.

If you want to specify what Zeek logs are ingested, you can use so-zeek-logs.

Zeek monitors your network traffic and creates logs, such as:

conn.log

  • TCP/UDP/ICMP connections
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/protocols/conn/main.zeek.html#type-Conn::Info

dns.log

  • DNS activity
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/protocols/dns/main.zeek.html#type-DNS::Info

ftp.log

  • FTP activity
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/protocols/ftp/info.zeek.html#type-FTP::Info

http.log

  • HTTP requests and replies
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/protocols/http/main.zeek.html#type-HTTP::Info

ssl.log

  • SSL/TLS handshake info
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/protocols/ssl/main.zeek.html#type-SSL::Info

notice.log

  • Zeek notices
  • For more information, see:

https://docs.zeek.org/en/latest/scripts/base/frameworks/notice/main.zeek.html#type-Notice::Info

…and others, which can be researched here:

https://docs.zeek.org/en/latest/script-reference/log-files.html

As you can see, Zeek log data can provide a wealth of information to the analyst, all easily accessible through Hunt or Kibana.

Configuration

You can use Salt to manage Zeek’s local.zeek, node.cfg and zeekctl.cfg:

local.zeek: The allowed options for this file are @load, @load-sigs and redef. An example of configuring this pillar can be seen below.

node.cfg: The pillar items to modify this file are located under the sensor pillar in the minion pillar file. The options that can be customized in the file include: interface, lb_procs, pin_cpus, and af_packet_buffer_size.

zeekctl.cfg: An example of customizing this can be seen below. The allowed options can be seen in https://github.com/Security-Onion-Solutions/securityonion/blob/master/salt/zeek/files/zeekctl.cfg.jinja.

Here is an example of how we would modify local.zeek. We can see the default pillar assignments used for local.zeek in /opt/so/saltstack/default/pillar/zeek/init.sls. This file should never be modified as it could be updated in the future and any modification made would be overwritten. The global or minion pillar files should be used for making changes as they are stored in /opt/so/saltstack/local/, and that directory isn’t overwritten during a Security Onion code update.

In this file, there are two keys under zeek, zeekctl and local. We will be using zeek:local for this example since we are modifying the zeek.local file. We will address zeek:zeekctl in another example where we modify the zeekctl.cfg file.

See also  Video pribadi, jangan ditonton.. menit ke- 01.14 bikin gagal focus..!!! | result sgp

Under zeek:local, there are three keys: @load, @load-sigs, and redef. In the pillar definition, @load and @load-sigs are wrapped in quotes due to the @ character. Under each of the keys, there is a list of items that will be added to the local.zeek file with the appropriate directive of either @load, @load-sigs or redef. In order to modify either of the lists, the entire list must redefined in either the global or minion pillar file.

If we have a node where protocols/ssh/detect-bruteforcing is generating a lot of noise and we want to tell Zeek to stop loading that script, we would do the following. Since we just want to turn it off for that specific node, we would open /opt/so/saltstack/local/pillar/minions/$SENSORNAME_$ROLE.sls. At the bottom, we would append the following:

We redefined the @load list in the minion pillar file, but we left out the `protocols/ssh/detect-bruteforcing. This will override the value defined in the /opt/so/saltstack/default/pillar/zeek/init.sls and the global pillar file if it is defined there, and prevent the script from being added to the local.zeek file. If we wanted to add a script to be loaded, then we would add out script to the list. Since we aren’t changing @load-sigs or redef, then we do not need to add them here. Once the file is saved, and the node checks in the with manager, the local.zeek file will be updated and the so-zeek docker container will be restarted.

Let’s see an example of how we would modify the zeekctl.cfg file. From the example above, we know that the default pillar values are set for zeek in /opt/so/saltstack/default/pillar/zeek/init.sls. The default pillar values for zeekctl.cfg are as follows:

zeek

zeekctl

For anything not defined here, Zeek will use its own defaults. The options that are allowed to be managed with the pillar can be found at https://github.com/Security-Onion-Solutions/securityonion/blob/master/salt/zeek/files/zeekctl.cfg.jinja.

In order to add or modify an option in zeekctl, we will need to modify either the global or minion pillar file. For example, if we wanted to turn log compression off and change the timeout for Broker communication events to 20 seconds globally, we would add the following to the global pillar file.

zeek

:

zeekctl

:

compresslogs

:

commtimeout

:

20

Since zeek:zeekctl is a dictionary with dictionary values, we do not need to redefine the entire pillar here like we did for zeek:local above. Once the pillar file is saved and the node checks in with the manager, the zeekctl.cfg file will be updated and the so-zeek container will be restarted.

Disabling

Starting in Security Onion 2.3.80, Zeek can be disabled by setting enabled: false in the zeek Salt pillar.

If you just want to disable Zeek on a single sensor, then you can edit that sensor’s minion.sls file. If the file doesn’t already have a zeek section, then add the following to the end of the file:

zeek

:

enabled

:

false

If you want to disable Zeek globally across all your sensors, then you could add that entry to your global.sls file.

[NEW] Install Zeek on Ubuntu 20.04 | zeek – Vietnamnhanvan

Follow through this tutorial to learn how to install Zeek on Ubuntu 20.04. Zeek, formerly Bro IDS, is the world’s leading passive open source network security monitoring tool.

Zeek is not an active security device, like a firewall or intrusion prevention system. Rather, Zeek sits on a “sensor,” a hardware, software, virtual, or cloud platform that quietly and unobtrusively observes network traffic. Zeek interprets what it sees and creates compact, high-fidelity transaction logs, file content, and fully customized output, suitable for manual review on disk or in a more analyst-friendly tool like a security and information event management (SIEM) system.

Install Zeek on Ubuntu 20.04

So how do you install Zeek on Ubuntu 20.04? Proceed as follows;

Zeek can be installed by building it from the source code or by directly via the Zeek APT repositories.

In this tutorial, we will choose the later.

Install Zeek on Ubuntu 20.04

To install Zeek on Ubuntu 20.04 from the Zeek APT repositories;

Add Zeek repository to Ubuntu 20.04:

echo 'deb http://download.opensuse.org/repositories/security:/zeek/xUbuntu_20.04/ /' | sudo tee /etc/apt/sources.list.d/security:zeek.list
curl -fsSL https://download.opensuse.org/repositories/security:zeek/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/security_zeek.gpg > /dev/null

Run system update;

apt update

Zeek 4.0.1 is the current stable release as of this writing, confirm the same by running the command below;

apt-cache policy zeek
zeek:
  Installed: (none)
  Candidate: 4.0.1-0
  Version table:
     4.0.1-0 500
        500 http://download.opensuse.org/repositories/security:/zeek/xUbuntu_20.04  Packages

You can then install Zeek by running the command below;

apt install zeek

During the installation, you will be prompted for some Postfix settings, choose Internet Site and enter your system FQDN.

Configuring Zeek on Ubuntu 20.04

Configure the Run-Time Environment

By default, Zeek is installed under /opt/zeek.

To begin with, add Zeek binary path to PATH;

echo "export PATH=$PATH:/opt/zeek/bin" >> ~/.bashrc
source ~/.bashrc

Define the Local Networks to Monitor

Next, you need to tell Zeek which local networks to monitor. This can be specified in the /opt/zeek/etc/networks.cfg configuration file.

See also  1000+ STACK NASUS SMASHING SEASON 11 | TFBlade | tfblade

The default networks defined are 10.0.0.0/8, 172.16.0.0/16, 192.168.0.0/16. So, in our case, the network we want to monitor is 192.168.59.0/24.

Hence;

vim /opt/zeek/etc/networks.cfg
# List of local networks in CIDR notation, optionally followed by a
# descriptive tag.
# For example, "10.0.0.0/8" or "fe80::/64" are valid prefixes.

#10.0.0.0/8          Private IP space
#172.16.0.0/12       Private IP space
#192.168.0.0/16      Private IP space
192.168.59.0/24      Kifarunix-demo IP space

Save the file and exit once you made your network configuration changes.

Configure Zeek Cluster

Zeek can be run in standalone mode or in a cluster setup. To define whether to run in a cluster or standalone setup, you need to edit the /opt/zeek/etc/node.cfg configuration file.

  • For a standalone configuration, there must be only one Zeek node defined in this file.
  • For a cluster configuration, at a minimum there must be a manager node, a proxy node, and one or more worker nodes.

According to Zeek quickstart guide, using the standalone / single process mode of Zeek is not suitable for setups with significant amounts of traffic. In these cases one will almost certainly want to make use of a Zeek cluster, even on a single system.

Therefore, we will see how to setup Zeek cluster. You can have a look at Zeek cluster architecture.

The default Zeek node configuration is like;

cat /opt/zeek/etc/node.cfg
# Example ZeekControl node configuration.
#
# This example has a standalone node ready to go except for possibly changing
# the sniffing interface.

# This is a complete standalone configuration.  Most likely you will
# only need to change the interface.
[zeek]
type=standalone
host=localhost
interface=eth0

## Below is an example clustered configuration. If you use this,
## remove the [zeek] node above.

#[logger-1]
#type=logger
#host=localhost
#
#[manager]
#type=manager
#host=localhost
#
#[proxy-1]
#type=proxy
#host=localhost
#
#[worker-1]
#type=worker
#host=localhost
#interface=eth0
#
#[worker-2]
#type=worker
#host=localhost
#interface=eth0

Since we are running a single node Zeek Cluster in this setup, comment out the Zeek standalone configuration, section under [zeek] and define host address for your Zeek logger, manager, proxy and worker.

So what are these components;

  • logger: it is an optional Zeek process that receives log messages from the rest of the nodes in the cluster. It can be used instead of the manager to reduce the load on the manager itself.
  • manager: receives log messages and notices from the rest of the nodes in the Zeek cluster if no logger is defined.
  • proxy: is a Zeek process that may be used to offload data storage or any arbitrary workload. A cluster may contain multiple proxy nodes.
  • worker: is the Zeek process that sniffs network traffic and does protocol analysis on the reassembled traffic streams.

So below is our single node Zeek cluster configuration setup;

cat /opt/zeek/etc/node.cfg
# Example ZeekControl node configuration.
#
# This example has a standalone node ready to go except for possibly changing
# the sniffing interface.

# This is a complete standalone configuration.  Most likely you will
# only need to change the interface.
#[zeek]
#type=standalone
#host=localhost
#interface=eth0

## Below is an example clustered configuration. If you use this,
## remove the [zeek] node above.

[kifarunix-demo-zeek-logger]
type=logger
host=192.168.59.16
#
[kifarunix-demo-zeek-manager]
type=manager
host=192.168.59.16
#
[kifarunix-demo-zeek-proxy]
type=proxy
host=192.168.59.16
#
[kifarunix-demo-zeek-worker]
type=worker
host=192.168.59.16
interface=enp0s8
#
[kifarunix-demo-worker-lo]
type=worker
host=localhost
interface=lo

Review Global ZeekControl configuration file

Next, you need to review the global ZeekControl configuration file, /opt/zeek/etc/zeekctl.cfg.

Most of the default values in configuration files should suffice. The only change you might want to make or update here is the recipient address for all emails sent out by Zeek and ZeekControl, if you have any set. The default value is [email protected]

Validate Zeek Configuration

Before you can install and start Zeek, you need to validate the configuration file;

zeekctl check
Hint: Run the zeekctl "deploy" command to get started.
kifarunix-demo-zeek-logger scripts are ok.
kifarunix-demo-zeek-manager scripts are ok.
kifarunix-demo-zeek-proxy scripts are ok.
kifarunix-demo-zeek-worker scripts are ok.
kifarunix-demo-worker-lo scripts are ok.

Deploy ZeekControl Configurations

If all is fine, install ZeekControl configuration and start the Zeek instance;

zeekctl deploy
checking configurations ...
installing ...
creating policy directories ...
installing site policies ...
generating cluster-layout.zeek ...
generating local-networks.zeek ...

Check the status of Zeek Instance

You can check the status of Zeek instance by executing;

zeekctl status

Zeek will start analyzing traffic according to a default policy and write the log results in /opt/zeek/logs/current directory.

ls -1 /opt/zeek/logs/current/
broker.log
capture_loss.log
cluster.log
conn.log
dhcp.log
known_services.log
loaded_scripts.log
notice.log
packet_filter.log
reporter.log
stats.log
stderr.log
stdout.log
weird.log

Some logs that are worth explicit mention:

  • conn.log: Contains an entry for every connection seen on the wire, with basic properties such as time and duration, originator and responder IP addresses, services and ports, payload size, and much more. This log provides a comprehensive record of the network’s activity.
  • notice.log: Identifies specific activity that Zeek recognizes as potentially interesting, odd, or bad. Such activity is called a “notice”.
  • known_services.log: This log file contains the services detected on the local network and are known to be actively used by the clients on the network. It helps in enumerating what all services are observed on a local network and if they all are intentional and known to the network administrator.
  • weird.log: Contains unusual or exceptional activity that can indicate malformed connections, traffic that doesn’t conform to a particular protocol, malfunctioning or misconfigured hardware/services, or even an attacker attempting to avoid/confuse a sensor.
  • (protocol).log such as (dns.log, dhcp.log, http.log, snmp.log): contains information for packets found in each respective protocol.

Sample conn.log logs;

Checking Zeek Node Processes

You can check processes running on each node by executing;

zeekctl ps.zeek <node>

For example, to check processes on Zeek manager node;

zeekctl ps.zeek kifarunix-demo-zeek-manager 
        USER         PID    PPID %CPU %MEM    VSZ   RSS TT       S  STARTED     TIME COMMAND
