FMC Syslog with Graylog Extractor

Let’s continue to talk about the Cisco Firepower Management Center, in this post we are going to look at sending connection events over to syslog. In this example I’m using Graylog which is an open source logging platform and  although any syslog server would work, one of the problems with syslogs is there is little uniformity when you have different systems sending these logs. One of the things that Graylog can to do is extract the raw message and put each part of message into a separate searchable field. We’ll configure the FMC to send syslogs and then configure an extractor on Graylog. Continue reading “FMC Syslog with Graylog Extractor”


Verifying DNS Lists – FMC

We are back with another post about Cisco’s Firepower Management Center and this time we are working with the DNS list which if you have a protect license you can have your Firepower modules or your FTD (Firepower Threat Defense) devices look at DNS requests and deny requests if they are malicious. These have to be applied on your access control policy to be able to use it and in this post we are going verify some of the domain names that are in this lists.

Cisco FTD Standalone

No management centers here, sometimes a standalone firewall is all you need. In this post I have a FTD appliance and there really isn’t a need tie this into Cisco’s Firepower Management Center. So we’ll configure appliance in standalone mode and go through the initial first steps that are required to get it online and walk through Firepower Device Manager. If you worked with Cisco FMC you’ll find its pretty similar, so with introductions out-of-the-way let’s get started!

Private VLANs

network-cable-ethernet-computer-159304.jpegLet’s start out 2018 with private VLANs, with PVLANs the network gets a little more privacy added to it. When we have privacy on the network we can seclude certain parts of it. Essentially, “you can go about your business – move along, move along”. Private VLANs allow us to segment networks within a single VLAN. So in this post we’ll go over the types of PVLANs as well as setup a network topology with private VLANs, Let’s get started!

Factory Reset Firepower 2100

In this short guide I wanted to walk through the steps to do a factory reset for the Cisco Firepower 2100 series. When doing these resets all configuration and the administrative password are removed, as well as the FTD (Firepower Threat Defense) app-instance. When the unit starts to boot it will reinstall the FTD app-instance to default configuration.
