May 19, 2017 A Practical History of the Firewall - Part 1: Early Days
As a practitioner in the relatively early days of the mass adoption of the Internet (mid to late 90s), I saw the rapid adoption and evolution of firewall technology. I had a limited view, and certainly have an imperfect memory, of this history. As such, over the next few posts, I welcome your comments to help me fill in the missing pieces of this story.

May 02, 2017 Breaking down the 2017 Verizon Data Breach Investigation Report
Verizon’s infamous Data Breach Investigations Report (DBIR) came out last week. It’s a testament to the diverse data Verizon now has that this year’s report is separated out by industry. In other words, more industries are seeing attacks and it allows the data to be divided and still hold merit. A few findings stood out to me as worthy of a deeper look...

Mar 29, 2016Centralizing Windows Logs in JSON with Security Analytics

In this post I will show how you can centralize your enterprise-wide Windows logs with zero cost and via one agent to Immediate Insight - security analytics for data discovery. We will output the logs in JSON (they show up a lot more rich than any other method that I have used - a huge improvement over Snare and others). You will use Microsoft's Windows Event Collector to centralize all of your Windows logs in your domain to one server and NXLog Community Edition to send those logs in JSON format over TCP syslog to Immediate Insight. Immediate Insight's Elasticsearch backend and built-in analytics make hunting, incident response, and general troubleshooting and triage extremely fast, easy, and straightforward.

Setup the Log Sending Hosts

On each log sending Windows server:

Enable the Windows Remote Management Service on the Windows servers that will be sending logs to your central Windows server.

Get to a command prompt and type winrm quickconfig - in this example my Windows Server 2012 R2 Standard x64 server was already setup.

01

Head to the Local Users and Groups and edit the Event Log Readers group to include the server that will be running Windows Event Collector to centralize the Windows logs (you will need to edit the Object Types to include Computers in order to find the computer successfully).

02

Head to the Windows Firewall configuration section in Settings and go to Allowed apps - edit as shown to allow only domain-based access to your events.

03

Setup Your Central Windows Log Repository

On the server that will run Windows Event Collector:

Enable the Windows Event Collector service on the Windows server that you are going to use to centralize all of your Windows logs.

Get to a command prompt and type wecutil qc and follow up with a y for yes to finish configuring the service.

04

Open Event Viewer on the Windows Event Collector server - go to Subscriptions and select Create Subscription...

05

Now - edit the Subscription Properties:

06

Give your subscription a name (mine is Remote Windows Event Log Collection. Set the destination log to Forwarded Events. Hit the radio button for collector initiated - then select the computers/servers that it is to collect logs from (alternatively, you can also use Group Policy to set it up so each source Windows log server sends logs).

07

Under events to collect - hit the Select Events... button. My settings are shown. If you have a lot of servers, you may want to setup multiple collectors (or perhaps use the aforementioned source computer log send via GPO).

08

The system warns you that you're being a bit ambitious. :)

09

Hit the Advanced... button and verify that the User Account radio button is set to Machine Account. Set the Event Delivery Optimization to Minimize Latency. You should be done configuring your subscription/collector.

10

Check the status of your subscription as shown:

11

Pop into the Forwarded Events view and you should see logs populating in from your servers.

12

Setup the JSON TCP Syslog Sender

Now, install NXLog Community Edtion - the default setup is fine. You will edit the nxlog.conf file located in C:Program Files (x86)

xlog to customize how your logs are sent. I have two tested and working conf files available for download here (you will want to edit the settings to match your environment). One is for logging in JSON format to disk and one is for sending in JSON format over TCP syslog to Immediate Insight (which is what I'm using for this blog - and it is shown below).

13

Restart the service once you have successfully edited your conf file - check the NXLog log (heh) at C:Program Files (x86)

xlogdata

xlog.log - you should see a message like below and start to see logs in your Immediate Insight.

14

The logs come in nicely via JSON in Immediate Insight:

15

Now for the fun stuff - using Immediate Insight's built-in security analytics (to bubble up interesting information in your data) and extremely fast search to explore your data with ease.

Tie it Together with Analytics

Association Analytics

This looks at frequency in your data - what is happening frequently and infrequently in several categories - along with doing automatic geolocation on all IP addresses upon data ingestion. Find outliers and explore them rapidly.

16

Event Clusters

This takes all of your data for the given time period that you're analyzing and places it in buckets based on the commonality within said data. A way for humans like yourself to use your business intelligence to analyze a large data set very quickly.

Common:

17

Unusual:

18

Activity and Change

You can also take a look at your data sets and compare them to other periods of time - how do they differ from the last hour, yesterday, etc. and what's new, missing, unchanged, and what is trending up and down...highlighting the anomalous very quickly.

19

Cohort Analysis

Guilt by association - what other data points has the data that you're looking at interacted with in the period that you're investigating?

Next: Sysmon Integration for Sexier Data

Thanks for reading. In my next post - I will take a look at how we can use Windows Sysinternals' Sysmon to make your Windows logs far sexier - logging things like process creation, hashes (SHA1, MD5, SHA256, or IMPHASH), loading of drivers and DLLs, disk/volume raw access, network connections, change in file creation time, and more! Create a force multiplier by using that information along with Immediate Insight's security analytics...

Jeff, as VP of Product Management for Immediate Insight, is continuing his pursuit of making data analysis more accessible. Jeff cofounded the Immediate Insight data analysis platform, which ws acquired by FireMon in 2015. He leverages 25 years of successes and failures in creating and developing markets, driving product strategy, and leading teams in both startup and public networking and security companies to create a new breed of data analysis required to discover the unknown in today’s mobile, virtual, and cloud-enabled environments.

Apr 27, 2017 The Life of a Firewall: Seamless, Automated Rule Lifecycle Management

So you’ve purchased a new firewall. Now what?

You’ve got to decide which access is allowed, which isn’t allowed and whether or not rules are compliant with internal and regulatory standards.

Things are running along smoothly and then the dreaded “change.” A user submits a new access request and the fun begins. Is this access necessary? Safe? Compliant? And what happens when it’s time to retire unused rules?

Apr 19, 2017 Closing the Complexity Gap

How Effective Security Management Can Help Teams Cover the Exponentially Increasing Gap between Technology & the Resources Available to Manage It

Security teams today are under tremendous pressure due to the rising frequency and impact of breaches and a business that wants to move faster and faster. The answer to both of these challenges has always been to add more technology and staff resources.

However, each new technology added creates complexity. More rules are created and more data is generated. As networks continue to evolve, this complexity will only grow. And while staff resources may increase, they will never match the exponential growth of technology.

FireMon calls this phenomenon The Complexity Gap and has set out to help security teams close it.

Join us for this webinar with Frost & Sullivan where we’ll explore the causes of “The Gap” and how workforce multipliers such as intelligence and automation help staff manage their security more efficiently and more effectively.

Mar 30, 2017 Data Orchestration for Incident Response
The biggest challenge security teams face when it comes to the alert triage process is preparing the data for analysis. Analysts can spend 80% of their time or more just to assemble the data to answer the question of whether an alert is a false positive or real incident.

Immediate orchestrates the data assembly process, freeing up critical time and resources to actually respond to identified events.

Join us for this webinar to learn how you can streamline the incident response process by orchestrating data assembly from a variety of disparate, external sources, including:
- FireMon Security Manager
- Palo Alto Networks AutoFocus
- VirusTotal
- Packet Capture
- Threat Intelligence Feeds
- And more!
