If you read the post here on the blog regarding a short history of Cisco Firepower, you recall that Cisco acquired a successful company named Sourcefire and this brought the Firepower technology into the company.

Let’s take a look at the progression of products that have resulted from this acquisition, and provide some more details on the latest technology (as of this writing) which is Firepower Threat Defense (FTD).

2013

  • Classic FirePOWER 7000 Series Appliances
  • Classic FirePOWER 8000 Series Appliances
  • VMware

2014

  • FirePOWER Services on ASA 5500-X
    • ASA5506-X, ASA5506H-X, ASA5506W-X
    • ASA5508-X
    • ASA5516-X
    • ASA5512-X
    • ASA5515-X
    • ASA5525-X
    • ASA5545-X
    • ASA5555-X

2015

  • Firepower Threat Defense on ASA 5500-X
  • Firepower 9300
  • VMware
  • AWS

2016

  • Firepower Threat Defense on Firepower 4100 Series
    • 4110, 4120, 4140, 4150
  • Azure

2017

  • Firepower Threat Defense on Firepower 2100 Series
    • 2110, 2120, 2130, 2140

Remember, FTD is so exciting because it represents the convergence of code from the Sourcefire FirePOWER software and the Cisco ASA software as well as the code representing new features.

The Sourcefire code is actually implemented as multiple software components inside the system and includes:

  • Firepower core software – includes Snort, Web server, database, and firmware
  • Software patches and hotfixes 
  • Snort rules
  • Vulnerability database (VDB)
  • Geolocation database (GDB)
  • URL filtering database
  • Security Intelligence Feed 
  • Local malware detection 
  • Integration components – might include ISE integration, AD integration, etc.

Cisco Firepower – A Brief History

Firepower

Sourcefire is a Hit

Sourcefire was founded in 2001 by Martin Roesch, the creator of Snort. The company created a commercial version of the Snort software, the Sourcefire 3D System, which evolved into the company’s Firepower line of network security products. Sourcefire was acquired by Cisco for $2.7 billion in July 2013.

What is Snort?

Snort’s open source network-based intrusion detection system (IDS) has the ability to perform real-time traffic analysis and packet logging on Internet Protocol networks. Snort performs protocol analysis, content searching and matching.

The program can also be used to detect probes or attacks, including, but not limited to, operating system fingerprinting attempts, semantic URL attacks, buffer overflows, server message block probes, and stealth port scans.

Snort can be configured in three main modes: sniffer, packet logger, and network intrusion detection.

  • In sniffer mode, the program will read network packets and display them on the console.
  • In packet logger mode, the program will log packets to the disk.
  • In intrusion detection mode, the program will monitor network traffic and analyze it against a rule set defined by the user. The program will then perform a specific action based on what has been identified.

The Cisco Sourcefire Integration

Cisco began integrating the Sourcefire technology into various Cisco appliances as soon as possible. For example, the ASA 5500-X and ISR routers began offering Sourcefire capabilities soon after the acquisition.

Cisco also began releasing new hardware platforms to showcase the technology including the:

  • Firepower 2100 Series
  • Firepower 4100 Series
  • Firepower 9300 Series

Today, the excitement revolved around the latest implementation of the Sourcefire technology in what Cisco has named Firepower Threat Defense (FTD). FTD represents the convergence of the Cisco ASA software and the Sourcefire technology into a central code base.

My Next Book! Mastering the CCIE Evolving Technologies Section

CCIE Evolving Technologies

You asked for it! You got it! Terry Vinson and I are putting together an e-book (and print) for you to master this section in most of the CCIE Written Exams. I have received more questions about this section of the written exams than any other topic (pretty much ever!)

Since Cisco Systems announced these new additions to the already brutally difficult written exams, students have been in a bit of a panic about finding the scarce training materials to address these topics.

Our text follows the current blueprint letter for letter. There are plenty of practice questions to build your confidence, and no topic is left unexplored.

Thanks to Amazon.com, we are able to bring this product to you for a price that makes sense – the e-book version will be just $9.99!

Note this text arrives quickly – our current publication date is May 31, 2017!
