TARGET of DEVELOPMENT WAN
• Connecting device-device dissociated in global area
• Presenting to connect full-time / part-time
• Operate on the wide geographical reach
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
Basically system of computer network represent
the open network system, therefore needed by
a network security to protect our activity during
in network

THREAT TYPE
 DOS/DDOS
 Worm
 Packet Sniffing
 Virus
 IP Spoofing
 Trojan
 DNS Forgery
 Junk Mail
 DNS Cache Poisoning
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
DOS / DDOS
Representing attack Form of at out for
computer network finish the resource a
computer equipments so that network
become annoyed
[At] this attack form, a host will accept
the initiation packet ( packet by flag is
SYN) in number very a lot of continually
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
PACKET SNIFFING
Elementary principle theft of this type of
is that any connection Ethernet is
connection having the character of
broadcast, where all host in a network
group will accept the packet delivered
by a host
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
IP SPOOFING
Is attack model which aim to cheat the
somebody. This attack is conducted by
altering origin address a packet so that earn
the through firewall which have been
attached
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
DNS FORGERY
That is conduct the deception of data DNS
To can to conduct this attack, a attacker require the
following information :
1.number of question Identity
2.port of question Target
3.Address IP, DNS, resolver
4.asked information
5.Question time
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
DNS CACHE POISONING
This method exploit the cache from every
server DNS representing repository of whereas
data domain which is non the responsibility
server DNS
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
WORM
Representing program disseminating by self by
delivering their/his self to system
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
VIRUS
Representing program which can insert the
self to other object like file
executable(*.exe) and some document type
which is often used
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
TROJAN
This type Trojan is very dangerous
because the program maker can infiltrate
to network system which have been
infiltrated by Trojan
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
JUNK MAIL
With the existence of Junk of Enamel or
garbage letter, will enlarge the capacities of
inbox of important other enamel so that
enamel cannot enter because capacity inbox
have full
Modul 18 DESIGN TO DEVELOP, BUILD AND ANALYSE THE WIDE of AREA NETWORK
QUESTION
Mentioning threat type which Is possible
became of the network WAN !
