The cb-event-forwarder can be installed on any bit Linux machine running CentOS 6. It can be installed on the same machine as the Carbon Black server, or any another machine.

Carbon Black Defense events can be sent to Sumo via its connector. For more in-depth information, see the Carbon Black documentation for Defense and Response. This section provides instructions for configuring the collection of Carbon Black Response events. Configure cb-event-forwarder. Once the service is installed, it is managed by the Upstart init system in CentOS 6. You can control the service with the initctl command:. This section provides instructions for configuring the syslog connector for Carbon Black Defense.

Multiple CB servers can be added. In Sumo, open a Live Tail tab and run a search to verify Sumo is receiving findings. Search by the source category you assigned to the HTTP Source that receives the log data, for example:. For more information about using Live Tail, see Live Tail. Collection overview Carbon Black Response events can be sent to Sumo Logic via its event forwarder mechanism.

These will be required in the next step. More details here. Step 3: Configuring the event forwarder for carbon black response This section provides instructions for configuring the collection of Carbon Black Response events. To configure collection of Carbon Black Response events, do the following: If it isn't already present, install the CbOpenSource repository. Additionally set the following variables in the cb-event-forwarder. Step 4: Configuring the syslog connector for Carbon Black Defense This section provides instructions for configuring the syslog connector for Carbon Black Defense.

To install and configure the cb-defense-syslog-tls, do the following on the target Linux system: Log in as root user. If it is not already present, install the CbOpenSource repository. Copy the example config file. While still logged in as root, test the new connector, in the following way: a. By default, the connector will run once per hour.All documentation will be updated in the coming months to reflect our new product names. The CB Response Live Response feature allows security operators to collect information and take action on remote endpoints in real time.

Quickstart Guide

These actions include the ability to upload, download, and remove files, retrieve and remove registry entries, dump contents of physical memory, execute and terminate processes. A sensor with an active session will keep an open connection to the Carbon Black server for as long as the session is active. Sessions are kept alive for a timeout period and then recycled once the timeout period has expired.

All Live Response command APIs require a valid session id; an error is returned if the session has not been established or has timed out. Note that Live Response is disabled by default. For example:. Note status is pending and the session id is 2. Wait a few seconds, then GET status of session For example, to get a process list:. Note status is pending and command id is 1. Wait a few seconds, then GET status of command 1 in session Other commands function broadly the same way.

See the documentation below and the python reference implementation for details. Happy hunting!

Returns a compressed archive of all the session contents: log of all commands, their results, contents of all files, etc. See Command Objects below for command object details. The contents of the command request object will vary based on the command requested and the context. Fields present in all command objects:. CB Response. API Reference.Am I wrong?

Why hasn't traditional AV created a similar product then? Carbon Black is far from the only player in the space. The way these "next-gen" endpoint systems work is by doing a deep analysis of every file, and like you said, uploading the hash to a central server for faster processing later.

Your use case is atypical for CB customers but I fully believe you're having these issues. There's a drawback to every kind of endpoint protection. It does seem that the more general population is worse off with traditional malware protection than CB, but your use case seems non-traditional. I should note that I am not affiliated with any endpoint product and AFAIK the absolutely massive company I work for doesn't even have an endpoint product that competes in the next-gen space. I do think it's technically superior when used right.

Namely, application whitelisting is technically superior. Most employees only have a small number of applications they need to run, and making sure everything else fails to start is the right choice. Obviously it's not perfect for everyone and technical staff will often need to run esoteric and constantly-changing applications, so whitelisting isn't always possible.

In that case, using a checksum and having the central server is a better way of handling it. Better yet is something like FireEye which can intercept your file downloads and scan them before it hits your machine. I can't speak for which next-gen endpoint solution works best since that's not my area of expertise, but I can say it's better than traditional AV which is basically useless. In that case, blacklisting is the better choice, for software no one should have installed.

I'm heavily involved in technology that, if the end user saw what we could see, they'd be horrified. Basically, if you're in the US and using your employer's laptop on your employer's network, you have zero privacy and everything you do and every site you visit is being logged into a central log repository and can be made available to the security and audit teams at a moment's notice.

Most of the time no one is watching it, no one except an AI looking for anomalies and reporting on outliers, but it's possible.

If you're using telnet or ftp or POP3, they know your passwords too, because they're likely sniffing internal network traffic as well and storing packet captures. And they may even be breaking SSL at the proxy or gateway level, so that doesn't help you. Basically, if you're worried that Carbon Black sending a list of your installed applications is your employer "spying" on you, they're already collecting far more data than you think.

Installed applications is the least of your concern. But again It's all owned by your company, and governed by their acceptable use policy in the employee handbook. P38 on Apr 10, All documentation will be updated in the coming months to reflect our new product names.

You are looking for the following- we will use those shortly to connect to the event bus. The most straightforward way to run through this is to have a VM or physical machine with CentOS 7 installed. Ensure pip is installed. See the Pika documentation for more information on creating durable queues. If you make the queue durable, ensure that once you start consuming events, you keep the consumer running at all times. Running the consumer on and off to drain the queue on a periodic basis will cause the RabbitMQ process to grow in memory and disk space very quickly, causing severe performance issues.

Most syslog servers cannot handle the intense load that we will place on them. For example, just on my test CB server with clients, I received multiple errors while testing the script pushing to the local rsyslog daemon on the CB server, such as:. You will also encounter some issues with the size of syslog messages; most syslog servers will silently truncate messages larger than a set size usually around bytes-1kb. Requesting large numbers of process documents in a single query will cause timeouts, so you will want to request data in smaller batches.

So you could do something like:. CB Response. Q: Does the default configuration of RabbitMQ support data persistence?All documentation will be updated in the coming months to reflect our new product names. The events can be saved to a file, delivered to a network service or archived automatically to an Amazon AWS S3 bucket.

The list of events to collect is configurable. By default all feed and watchlist hits, alerts, binary notifications, and raw sensor events are exported into JSON.

The cb-event-forwarder can be installed on any bit Linux machine running CentOS 6. It can be installed on the same machine as the Carbon Black server, or another machine. Otherwise, it is acceptable to install the cb-event-forwarder on the Carbon Black server itself.

If there are any errors, those errors will be printed to your screen.

By default, CB publishes the feed. If you want to capture raw sensor events or the binaryinfo. By Default the Message Bus listens on port Ensure firewall rules allow for incoming and outgoing TCP connections to this port. We have seen a performance impact when exporting all raw sensor events onto the enterprise bus. We do not recommend exporting all the events. We recommend that at most, only process and netconn events be broadcast on the event bus. Once the service is installed, it is managed by the Upstart init system in CentOS 6.

You can control the service via the initctl command. The Carbon Black event forwarder can be used to export Carbon Black events in a way easily configured for Splunk. It is recommended that the event bridge use a file based output with Splunk universal forwarder configured to monitor the file. More information about configuring the Splunk TA can be found here.

I wrote about this phenomenon a few months backand promised to report back on the various companies that sell EDR tools and solutions. Today I am presenting the first of my reports, a neutral and objective discussion of Carbon Black, which from where I sit, is an EDR powerhouse.

A few research notes: 1 I actually deployed Carbon Black in the context of a large data breach response engagement; and 2 Last week, I spoke at length with Ben Johnson, one of the Founders of Carbon Black with whom I had never met or spoken before.

Typically installed within a swath of IT equipment including domain controllers, database servers and workstations, EDR technologies provide an ongoing rich and in-depth of behavior-based anomaly recognition and acute visibility into threats of all varieties, not just malware. For instance, suppose a corporate network scan reveals an indicator of compromise or some other anomaly or form of malware in its systems. Of course, many immediate questions arise such as: How did the file get there?

How long was it there?

Where has that file been before being detected? What other computers has it been opened on? If it executed, what did it do? For most organizations, the requisite information required to answer these questions is not being actively captured.

This is why most internal data breach investigations kick off with manual data preservation and acquisition, file-system forensics and log file analysis on all of the data amassed and collected after the suspected breach — which is too often a time consuming, costly and tedious IR drill.

By providing continuous monitoring and recording of activity on endpoints and servers, EDR tools tackle this challenge head-on. EDR tools reduce the need for such after-the-fact costly and wearisome data collections while also: 1 accelerating the identification of root causes and attack vectors of data breaches; and 2 decreasing the cost, complexity and time of internal investigations and regulatory response.

EDR tools have quietly ushered in a new generation of cybersecurity, geared more towards the cybersecurity paradigm of response rather than prevention and detectionwhich is far more realistic and effective. Every company can experience a data breach — and probably already has. That is why companies need to shift cybersecurity practices away from prevention and detection and recalibrate cybersecurity into a more effective archetype of response.

When companies trying to prevent data breaches rely too much upon customary protections of intrusion detection and firewalls, they are just as misguided as parents trying to prevent their kids from catching colds by relying upon hand washing and multiple clothing layers. The smarter method for combating data breaches like colds is to focus efforts and preparation on how to contain, treat, and cure the problem, as fast and as painlessly as possible.

Company executives should preach this realism, rather than the fantasy of ironclad security. Carbon Black embraces this new paradigm.

Through continuous endpoint recording, customized detection, live response, remediation, and threat banning, Carbon Black makes advanced threats easier to see and faster to contain. Carbon Black abandons traditional signature detection, which has failed so many companies in so many ways.

Specifically, Carbon Black boasts five core capabilities: visibility, detection, response, protection and integration.

Rather than scanning reactively, Carbon Black continuously records the critical data necessary to utilize multiple forms of threat prevention, builds customized threat detection and responds at the moment of compromise.

This means that Carbon Black gathers the relationships of every file execution, file modification, registry modification, network connection and cross-process event while maintaining a copy of every executed binary for all major operating systems Windows, Mac OS X, and Linux. Rather than requiring remote connections, Carbon Black stores historical data in a central facility, deployed onsite or in the cloud as a hosted service for rapid one-stop-shopping remote access.

From one console, one investigator can analyze an entire enterprise. This dramatically reduces the initial and very costly phase of incident response where preservation of data and access to data can take weeks. This retrospection is what makes EDR tools so different — and so powerful. So many times, an IR team arrives on site and historical data is lost, piecemeal or otherwise incomplete, which can trigger criticism, not just from customers, vendors and partners but also from regulators and law enforcement.Posted by esullivan 4 weeks ago.
