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 15, 2016Rapid PCAP Analysis with Analytics

In this post I show you how one can use the built-in security analytics in Immediate Insight to help you rapidly review a large PCAP file for anomalies. Immediate Insight is security analytics for data discovery - purpose-built for incident response, investigation, and triage.

1) Collect the PCAP. Here I am using my Fortinet FortiWifi 90D's built-in packet capture functionality - you can also use tshark or whatever your favorite packet capture methodology du jour is. Immediate Insight does not use parsers - its natural language system can take in any human-readable data (PCAP, PST files, PDF, Microsoft Office documents and spreadsheets, configuration files, IP reputation files - the list goes on).


You can even stream PCAP in real-time to Immediate Insight:


2) Use Immediate Insight's Drag and Drop Import functionality to ingest the PCAP quickly and easily - tag the data with a unique term (I used fwf90dpcap). This tag will be used to search and use the built-in analytics in Immediate Insight only on this specific file (you can also, of course, review all of your data together - including this file). Be sure to review the Import Time settings (set it to the current time - or now - or set it to the time stamps found within whatever file you are dragging into the system) to make sure they match the overall purpose of your investigation (the Drag and Drop Import functionality is primarily designed to supplement the real-time data coming into your system - such as syslog, flat-files, NetFlow/IPFIX/sFlow, and much more).


3) Search on your tag (fwf90dpcap in this case).


The default Search Results page will display very much like what you're used to with a SIEM. However, one of the main goals of Immediate Insight is to encourage exploration and the discovery of the unknowns (with support for both structured and unstructured data) - I will be focusing on some of the analytics components in this post.

Clicking on Explore > Entities will take you to Immediate Insight's Association Analytics featuring a look at both frequent and infrequent entities (things like URLs and IP addresses), locations (Immediate Insight does automatic geolocation enrichment at time of data ingestion), addresses (IP addresses), networks, sources (where the data came from - i.e. syslog), and names.

Furthermore, clicking on Analytics > Most Common will take you to Immediate Insight's Event Clusters functionality. This is an incredible tool for going through large datasets or finding the unknown unknowns. It takes the entirety of the dataset that you're reviewing and finds the commonality in the data - grouping similar data into buckets so a human can rapidly determine what is happening. In the image below - you can see that a very complex event has been boiled down to its essence for the purpose of human analysis.


You can click on the black and white circle to highlight unusual terms - adding further ease to the review. You can also flip the data over and look at the unusual items (versus the common, by default).

This is just the tip of the iceberg regarding the capabilities of Immediate Insight from FireMon. The free, Community Edition is full-featured and supports up to 25 million events - it's a VMware OVA that you can deploy within 10 minutes in VMware Workstation, Fusion, ESX, or vSphere. Give it a try. Come back when you're ready to take advantage of our nearly infinite horizontal clustering capabilities for big data. Contact me if you'd like to see a demo, would like assistance working with your visibility and data ingestion use cases, or if you just plain want to geek out on this cool software.

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.

Jun 06, 2017 2:00 pm - 3:00 pm PDT Top 5 Risks of "Dirty" Firewalls
Firewall rules are notoriously complex and voluminous in nature. Even small organizations have multiple firewalls and significant complexity. But large organizations are overwhelmed.
May 23, 2017 2:00 pm - 3:00 pm PDT Der Countdown läuft, noch 365 Tage bis zur DSGVO (GDPR): Machen Sie Ihr Netzwerk fit für Compliance
Netzwerksicherheit ist deutlich mehr als Cyberbedrohungen nur zu stoppen. Es geht auch darum für das Unvermeidliche gerüstet zu sein. Nämlich einen Datenschutzvorfall, den die Technik allein nicht hat verhindern können. Die EU Datenschutz-Grundverordnung (kurz DSGVO GDPR) ist, neben anderen mehr, ein solches Compliance-Rahmenwerk mit dem Unternehmen sich auseinandersetzen müssen und das im Mai des kommenden Jahres in Kraft tritt. Dann sind Unternehmen beispielsweise verpflichtet innerhalb von 72 Stunden nach einem Datenschutzvorfall darüber zu informieren.

Organizations are taking a more active role in detecting and responding to advanced attacks – Threat Hunting. In this webinar, you’ll discover the steps you can take to launch your threat hunting capabilities.
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!
