00:00:04

hello and welcome charaf by watching

00:00:07

this video where we will discover

00:00:08

together how to use

00:00:10

the expert training of your purchases

00:00:13

the expert information simply represents

00:00:16

an extremely

00:00:17

interesting module in terms of your purchases

00:00:18

facilitating analysis on your case

00:00:21

of forensic analysts of rivals or

00:00:23

even search for anomalies

00:00:25

the latter will keep track of the

00:00:27

anomalies and other elements of interest

00:00:30

that it will find in a

00:00:31

capture file is true the posters and not the

00:00:33

cheese dialog box an expert

00:00:35

the goal is to give you a

00:00:36

better idea of

00:00:38

unusual or notable network behavior is to allow

00:00:40

novice users as well as

00:00:43

experts to find

00:00:45

network problems more quickly therefore manually go through

00:00:48

the Easter list and the

00:00:51

amount of information depending

00:00:54

largely on the protocol used

00:00:56

speaking that the ten sectors

00:00:57

when certain current protocols like

00:01:00

tcp ip edge will be

00:01:01

detailed information others so we

00:01:03

will not display or little the ifo machine

00:01:05

expert can be found at

00:01:08

the angle is analyzed and expert training

00:01:10

from there you will have the

00:01:12

different information which will be

00:01:14

displayed as well as the

00:01:15

corresponding packages when you click

00:01:17

on one of the packages you will be redirected

00:01:19

to these

00:01:22

each element of the expert information

00:01:24

a level of severity the

00:01:25

following levels are used from the lowest cost to

00:01:28

the highest we start with

00:01:30

azure blue yellow and red blue here

00:01:34

for example it is the least

00:01:36

serious category or call 4c information on

00:01:39

usual workplaces for

00:01:41

example a tcp packet with a

00:01:42

sign indicator defined as azure and will

00:01:46

represent in notable events

00:01:48

for example an application which sent

00:01:50

a common rock side such as http 404

00:01:53

the young one is or horny to

00:01:55

the warning

00:01:56

generally when one generally has

00:01:58

an attack or when an

00:02:00

application returns an unusual error code

00:02:03

a connection problem therefore for

00:02:06

attacks it is sure that indicators

00:02:07

are not necessarily these are in red

00:02:11

so these are serious problems such as

00:02:13

packages my form we find here

00:02:15

also an example so you do not attack

00:02:18

eminem or li expert training will

00:02:21

clearly mean to us meat

00:02:23

online an attack which is has been

00:02:25

duplicated slow for him it is a configuration error

00:02:29

but for us it clearly means

00:02:31

that two addresses have the same

00:02:33

mac address which is logical and which will

00:02:36

therefore simply be able to concern the

00:02:37

afte protocol and more precisely an

00:02:39

arx refinement type attack which is

00:02:41

used in this context and if we

00:02:43

notice the usual traffic generally

00:02:45

here in Asia we note here also

00:02:49

different suspicious frames therefore but

00:02:52

nothing really very serious with the

00:02:54

warnings in young people without forgetting the

00:02:56

horrors in red as you can

00:02:58

see here

00:02:59

this can therefore allow us to

00:03:01

collect enough information to

00:03:03

be able to find the source of an attack

00:03:04

or to understand the different

00:03:07

causes of a very specific anomaly

00:03:12

here you also have the group of

00:03:15

different anomalies detected at the

00:03:17

level of the official documentation of the

00:03:19

repurchase

00:03:20

you will be able to find how many to

00:03:22

say but also to the graduates of

00:03:25

each group and its objectives then here

00:03:28

for example for the error on red

00:03:30

we saw that it was wrong forints so if

00:03:33

we come back to it here we see that it is

00:03:35

quite simply poorly formed packets

00:03:37

or bugs at the level of said sector for

00:03:39

the part that gets stuck we see although

00:03:41

it is a number of

00:03:42

protocol sequences which is suspicious and we have

00:03:45

not had a transmission in for

00:03:48

example continuous or there is a

00:03:51

motorized retransmission which has been

00:03:53

detected

00:03:55

of course it can be a false positive and

00:03:57

it is interesting to be able to continue

00:03:59

your analysis in more depth

00:04:00

we can also simply add the

00:04:03

x disturbance column by

00:04:05

right clicking on

00:04:06

any column

00:04:07

columbine 16 years old click on had so

00:04:10

here I can put for example experts

00:04:12

and at the level of the type we will

00:04:16

simply choose the word xp is formed at

00:04:19

cerruti which will tell us if the

00:04:22

traffic is legitimate traffic for of

00:04:25

course the module or displayed in quite

00:04:28

simply the category where it has in

00:04:30

quite simply been classified have brought back

00:04:34

here and there as you can see we

00:04:36

can display it quite simply so here

00:04:39

for example we have the different bourny

00:04:41

we have the different information

00:04:43

similarly the notes the overall information

00:04:46

on the legitimate traffic finally legitimate the

00:04:49

normal traffic that it has classified as

00:04:52

normal and so on

00:04:55

I say thank you for your trust and see you

00:04:58

next time

Wireshark est l'analyseur de paquets et protocoles réseaux Open Source, il vous permet de voir ce qui se passe sur votre réseau en détail. Wireshark est utilisé dans le dépannage et l’analyse de réseaux informatiques dans de plusieurs entreprises commerciales et sans but lucratif, des agences gouvernementales et des établissements d'enseignement. Le développement de Wireshark a évolué grâce aux contributions volontaires d'experts en réseautage du monde entier et est la continuation d'un projet lancé par Gerald Combs en 1998. # Qu'est-ce que vous allez apprendre dans cette formation Wireshark ? Au cours de cette formation, vous allez tout d'abord manipuler les différentes fonctionnalités de Wireshark. Vous allez comprendre l'analyse réseau avec Wireshark, vous allez apprendre les méthodologies et les approches d'analyse, comme vous allez installer et configurer Wireshark sous différents environnements. Vous allez faire du listing avec Capinfos, vous allez capturer le trafic avec Dumpcap et Mergecap et découvrir l'outil Tshark. Vous allez aussi maîtriser le dépannage réseau à distance, les paramètres généraux et personnels et la création de filtres d'affichage et de capture. Également, vous allez effectuer des suivis et du réassemblage de flux et exploiter le système expert de Wireshark. Ensuite, vous allez apprendre l'analyse protocolaire et l'analyse avancée de flux réseaux. Vous allez vous initier à l'analyse protocolaire avec Wireshark et apprendre les trafics ARP, DHCP, DNS et HTTP. Comme vous allez apprendre a analyser le Traffic VoIP et WLAN, vous allez par la suite appréhender les IoC d'infection réseau et apprendre à exploiter les graphes et extraire les mots de passes d'une capture réseau. Après, vous allez découvrir l'analyse forensique des réseaux avec Wireshark et apprendre à identifier des attaques sur le réseau. Vous allez vous introduire à la notion et à la méthodologie d'analyse forensique et comment effectuer du forensique réseaux avec Wireshark, comme vous allez comprendre les mesures anti forensique, apprendre à réaliser le reporting et comprendre le déroulement d'une Kill Chain. Vous allez apprendre aussi à détecter les attaques par dénis de service et Brute Forcing, les attaques DHCP Starvation, les attaques ARP spoofing, les attaques des exfiltrations de data, les trafics suspicieux les attaques des scan réseau. Enfin, vous allez découvrir les outils complémentaires à Wireshark. Vous allez maîtriser les NIDS, exploiter Snort et maîtriser l'analyse à grande échelle avec une étude de cas Moloch et Wireshark. + La mise en place d'un LAB de simulation La présente formation Wireshark repose sur un LAB virtuel simulant un environnement réel pour pouvoir comprendre et appliquer les notions expliquées par le formateur lors des vidéos tutoriels.
