Are you looking to analyze all your logs

and events in one location, or maybe

you're just looking to learn about a Sim

tool like Splunk to prepare for a job in

it or cyber security? Well, look no

further. In this video, we're going to

walk through installing and configuring

Splunk which is one of the leaders in

log and data analysis on a Windows

system. But first, welcome to the channel

or welcome back. My name is John Good and

on this channel. We talk all about cyber

security. If you enjoy the content, make

do this. In IT cyber security and even

devops, one of the biggest issues that we

have is monitoring our networks and

being able to look at large amounts of

data at once. If we have two computers

yeah looking at the logs individually is

going to be possible, but it's going to

be annoying if we have a th systems. It's

basically impossible to do that and stay

current with all the events that are

taking place on those systems. Splunk is

one of the leaders and helping us

analyze large amounts of data in one

central location. So it's a pretty good

idea that you become familiar with how

it works. We also refer to Splunk as a

Sim tool which stands for security

information and event management. At a

high level, Splunk operates basically

like a database with its own specific

language called search processing

language or SPL. The better that you can

navigate SPL and Splunk itself the more

desirable that you'll be to employers.

There are even jobs that are dedicated

to configuring and managing Splunk

installations. And even if you had to use

a similar product, you'll have a good

idea of what's going on. The goal in this

video is to get a free Splunk

installation running on a local system,

and then show you some of the basic

features that you should know after this

video. You'll be able to learn additional

capabilities of Splunk or at least be

able to talk about Splunk and how to use

similar tools. Before we dive into the

demo, I'm assuming that you already have

a virtual machine or a system to install

Splunk on for this video. I'll be using a

Windows Server 2022 virtual machine,

since we typically install Splunk on a

server. But the process is going to be

the same on any Windows system, all right.

Let's begin. Okay, so the first thing that

you have to do is you have to go to the

Splunk website. So splunk.com because we

need to download Splunk. So we're going

to go to products, we're going to go to

Splunk

Enterprise, all right, and then we're

going to click free

trial, and you'll have to create an

account if you don't already have one in

order to download Splunk. And once you

log in you need to go ahead and download

Splunk, and get the correct download

depending on which operating system that

you're using, okay. Now, that download is

done go ahead and open that file and

we're going to install Splunk and we're

going to use a lot of the defaults in

this. But of course, if you were in the

real world, you might customize some of

these options. We're going to go ahead,

and check the box to accept the license

agreements and we're just going to hit

next and these are the defaults that

it's going to use. So it's going to run

Splunk Enterprise as a local system

account. It's going to use this directory,

and then it's going to create a start

menu new shortcut. So again, we're going

to use a defaults we'll hit

next. We're going to create a username

and a

password and then we'll hit

next and we'll hit

install. So that username and password is

really important because that's what

you're going to use to actually log into

Splunk. Okay, so we've successfully

installed Splunk Enterprise and we're

going to leave this launch browser with

Splunk Enterprise checked and we'll hit

finish and we'll open it with our web

browser okay. Do you remember when we

originally installing and configuring

the installation for Splunk, and we had

to create a username and password. That's

what we need to enter here. So we can log

in. We've now successfully installed

Splunk, and we've logged in. Now, we need

to set up our logs actually being

adjusted into the tool. So we're going to

go to settings and then data inputs. For

this video, we're only going to deal with

local events. We're not going to deal

with remote systems, so we're going to go

under local event log collection. We're

going to select

edit. Now, we need to select the logs that

we want to actually injust into the tool.

So I'm going to keep it really simple,

and just do application security and

system. Those are kind of the

foundational logs. We'll scroll down and

we'll select

save okay, and the status should be

enabled because that's going to ingest

those logs. And we'll go back to apps in

Search and Reporting all right in the

search bar here. We're going to put in an

asterisk or a star and we're going to

hit return to search for all the events

that it knows about. As you can see, it's

starting to get events from our local

system again. In this video, we're just

dealing with the local system not remote

systems. So this would be a very basic

kind of search. We can do all kinds of

different basic searches in here. We can

also get a little bit more advanced with

filters and different queries and

parameters and things like that for this

what I'm going to do is I'm actually

going to open up our Event

Viewer. So I've gone to the windows menu,

and I'm going to open up Event

Viewer, and I'm going to go under Windows

logs and

security. I'm going to rightclick this,

and I'm going to select clear

log, and I'm going to select clear. So

it's going to clear the security log and

I'll show you why I'm doing this here in

a second. So if if we go back into our

system here in our Splunk

system, we're going to actually narrow

this down a little bit and I'm going to

show you how you can do this. So all of

these parameters and fields if I select

one. So for instance the host, I'm going

to left click on this and I'm going to

do add to

search, that's going to add it in this

search bar and we're going to slowly

narrow this search down. And then the

next one I'm going to do is source. So we

want it from from the security

logs, and then the event code I want to

also add in here. So I'm going to add

this to our

search, and this did not add the full

thing here but that's okay. We're going

to add equal sign and then we want 112

is the event that we want to

find, and we'll hit

return and that's how you can narrow

down the searches. So we've only got this

one particular event,

which this event was the audit log being

cleared. That's what we just

did great. So that's an example of how

you can search in Splunk for specific

things now. I'm going to copy this

because we'll need it

later, and then I'm actually going to

select create table

view. We'll skip the tour because again, I

don't care about that and this will

actually put this into a

table and, and then on the left here, you

can select or deselect different types

of logs. So I'm going to actually

unselect raw. So it's not going to give

us all that information and I'm going to

hit

done okay. And as you can see that gave

us a table with the fields that we've

selected. I hope you're enjoying the

content so far. If you are, make sure to

check out the description for more

training and resources, all right. Let's

get back to the content now, I'm going to

go to

dashboards and again I'm going to skip

the

tour and I'm going to select create new

dashboard and we're just going to label

this clear

logs and we're going to create this with

the dashboard

studio and we're going to do

grid select

create. All right, so now we can create a

dashboard. Dashboards are huge for

analyzing data because we can quickly

display C. Certain things and especially

in areas like security or it or any kind

of data analytics, you're probably

looking for relatively specific things

and this way anything you're

consistently looking for, you can just

put into a table or a graph or something

like that and put it on a dashboard so

you can easily view it as it happens. So

we're going to add a chart here, we're

going to add a

table and we're going to paste in this

search with SPL that query that we

already found to find the event logs

being cleared. So as you can see this

looks exactly like it did in our other

search, all right. And we're going to

select apply and

close, we're going to give this a

label and we're not really going to

customize this at all, but you could in

the column formatting. You can add things.

You can also remove things,

too. So if we go up here and we actually

edit our

search. I'm going to show you how, you can

eliminate some of these columns if you

didn't want them. So we can add a

pipe and then we're going to type

Fields a

minus and then we're going to type the

actual field in

here. So

bkt and CD we're going to

eliminate. We'll select apply and

close and as you can see those columns

are no longer in here. So you can totally

customize it however you want to see

it, and then we're going to select save

to save this dashboard, save this

table right. So that's saved now if you

go back under dashboards. So just

clicking dashboards from wherever you're

at within the application, you'll see

that your dashboard is in here. So we're

going to actually click on our dashboard

that we created. So the clear

logs and this is going to be the table

that we

created. If we do actions and we select

set as home dashboard, that's going to be

our primary

dashboard. So this is just going to be on

the the search and Reporting application.

So having a dashboard like this is

extremely useful again, you can look at

very specific things that maybe you're

constantly looking at or things that you

need to view at a quick glance

especially when you're dealing with

executive level or management level

leaders. This can be great because you

can easily present information in an

easy to read way that they like to see

it. So they're not confused by all the

nuances or smaller details of the

application. It's just extremely

beneficial to be able to create

dashboards and easy to read

information. So then if I go somewhere

else. So let's just click anything. We'll

just click data inputs under the

settings, just so we can get onto a

different

screen and then we're going to go back

to

apps and actually we'll click Splunk

Enterprise to take us back to the

homepage. There is clear logs right on

that main page. So again you can do

whatever you want as far as the

dashboard, and what you have in there

what kind of tables and stuff but that's

just an example of what you can do with

dashboards to quickly and easily display

information. So one other website that's

extremely useful is this ultimate IT

security. They have all the event IDs for

Windows that you'll ever need and then

for instance we have 1102 the audit log

was cleared that's what we were just

looking at. If we click on

this, you can see it has even more

details about specifically what it is. So

if you ever aren't sure what an event ID

is or you need something specific, this

is a great resource to use question of

the day what are some important events

or logs that we might want to monitor in

Splunk, let me know down in the comment

section below in this video we walk

through installing and configuring

Splunk which is one of the leading Sim

Tools in login data analysis. Remember

knowing a tool like Splunk is extremely

helpful in your career and will make you

more desirable by employers. As always,
