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...

Apr 05, 2016Enhance Windows Anomaly Detection with Sysmon

In my last post I covered how you can centralize your Windows logs on one system, send them as JSON for full detail, and use Immediate Insight's fast search and analytics to investigate alerts and discover the unknown. Now - let's take it a step further and use Sysinternals' Sysmon to capture rich details from your workstations and servers. Details like process creation/termination, file creation, driver load, network connections, and more. All of this data can then be rapidly queried, correlated, and alerted upon within Immediate Insight.

    1. Download Sysmon - I personally place all of my utilities in a folder called C:Util and then I add that folder to the system's path as shown below.


      Immediate-Insight-Environment-variables

    2. You're now ready to install and configure Sysmon for your environment. This component requires some planning - as Sysmon generates a ton of log data. However, the quality of that data is quite high - so you'll want to balance the configuration between your storage retention capabilities and your security requirements.You can also chose to just load a quick default configuration:

      Immediate-Insight-Admin-command-prompt

      sysmon -i - accepteula -h md5 -n -l

      The above installs Sysmon as a service (so it will survive reboots) and will collect data on the loading of modules, log network connections, and record MD5 hashes for any processes created.

      Immediate-Insight-Admin-command-prompt-2

      If you want to get more in-depth: here are links to two Sysmon configuration XML files that you can review and edit on your own, conveniently pre-configured for both servers and workstations. They are excellent starting points.

    3. Create a subscription for collecting remote Sysmon events (very much like what you did in the last blog post for standard Windows logs).

      Select the computers from where you want to collect the Sysmon data:

      Immediate-Insight-subscription-properties-2

      Define the query filter to grab the Sysmon events:

      Immediate-Insight-subscription-properties-3

      Unfortunately, by default, Windows Event Collector will be unable to access the Sysmon logs in the same way as it does standard logs (Application, Security, System, etc.).

      Immediate-Insight-subscription-runtime-status

      You will need to set additional permissions. For each server or workstation that will be running Sysmon and centralizing those logs you will need to add the Network Service local account and the event collector local computer account into the Event Log Readers local group:

      Immediate-Insight-event-log-readers

      You will also need to use your domain's (or if you lack a domain - set it locally on each machine) Group Policy Management Editor to give those same two accounts permission to Manage auditing and security log as shown:

      Immediate-Insight-auditing-security-properties

      Finally - reboot each changed machine. Hey - I didn't say this would be completely easy. :)

    4. The end result is great looking Sysmon data coming into your Immediate Insight system in JSON. Here they are under the Microscope in Immediate Insight (a great place to examine your data in great forensic-esque detail):

    Immediate-Insight-microscope

    Use Association Analytics to examine patterns of frequency and infrequency within your dataset - entities, geolocated locations (at time of data ingestion), IP addresses, networks, and more...rapidly investigate what is outside of the normal.

    Immediate-Insight-association-analytics

    Use Event Clusters to investigate a large dataset rapidly - Immediate Insight finds commonality in your data and puts it in buckets so you can find both common and unusual anomalies quickly. What data looks strange?

    Immediate-Insight-event-clusters

    Visualize your data using the Timeline. Look for outliers - spikes in traffic or strange locations (either in the U.S. or in the World).

    Immediate-Insight-time-slices

    Check Activity & Change to investigate how your data has changed since other periods of time - is traffic significantly higher than a normal Monday at this time? Significantly lower? Dig in! Find new data that wasn't there before - is it just a new system or application coming online or is it something anomalous?

    Immediate-Insight-activity-and-change

    Take a look at the Firehose to see the data streaming in live - pause and filter to troubleshoot in real-time when there is an ongoing issue or incident:

    Immediate-Insight-firehose

    Thanks for reading - I hope that you found this post useful. Sysmon is an incredibly powerful tool that makes Windows logs substantially more valuable - it is very worth the effort to deploy it where it makes sense within your organization.

    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
