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...

Nov 02, 2015Configure Multiple Network Interfaces

The purpose of this document is to show Immediate Insight users how to configure additional network interfaces from the command line.

Caution:  If you connect both eth0 and eth1 to the same network/switch this will cause a bridge loop & connectivity problems, they must be on separate networks / subnets.

One use case would allow for a management and data networks to be on a different subnet.

    1. Connect to the CLI of the Immediate Insight instance using Putty or your terminal emulator of choice.
    2. Edit the following files adding the lines show below.
      1. /etc/network/interfaces
        1. iface eth1 inet static = (static IP configuration, e.g.)
          • address 192.168.1.100
          • gateway 192.168.1.1
          • netmask 255.255.255.0
        2. iface eth1 inet dhcp = (DHCP IP configuration)
      2. /etc/rc.local
        1. ifconfig eth1 up
    3. Run the command ‘sudo reboot’

    Another use case is would be to use eth1 as a promiscuous mode packet listener without an IP address.  Edit the files below adding the lines indicated.

    1. /etc/network/interfaces
      • iface eth1 inet manual      (this forces it to have no IP address)
    2. /etc/rc.local
      • ifconfig eth1 up
      • ifconfig eth1 promisc
    3. Then ‘sudo reboot’

    ** below is Immediate Insight configuration for a packet listener command, making use of the eth1 promisc port**

    Edit the Packet Capture command in DataFlow -> Remotes to assign the eth1 interface. Do this by adding the –i eth1 to the command string (the default is eth0)

    (echo ‘@@sourceFile:tsharktag’; sudo tshark -i eth1 -b filesize:5000 -b files:5 -w /tmp/tsjunk -t ad -T fields -e frame.number -e col.Time -e col.Source -e col.Destination -e col.Protocol -e col.Length -e col.Info -E header=n -E separator=, -E quote=d ‘not(host @@agentIP)’) |nc @@serverIP 3003;sudo rm /tmp/tsjunk*

    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.

    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!
