ANALISA PERFORMANSI INTERNET CONTROL MESSAGE PROTOCOL (ICMP) DALAM KAITANNYA DENGAN SISTEM KEAMANAN JARINGAN KOMPUTER PADA PROTOKOL TCP/IP

xiii

At the moment the problem of security at computer network have become

important shares which must be majored by every consumer of computer specially

governance organization and company, because badness case as a mean to bother

computer system a company/governance organization is growing of. Expanding of

this security system affect also its effort to look for other security hole. Among

him by doing detection, infiltration even attack at one particular goals of host by

exploiting protocol of ICMP.

Internet Control Message Protocol (ICMP) is protocol at TCP/IP

commisioned deliver messages of other condition and mistake which need special

attention. Type order at ICMP there is two, that’s ICMP Error Message and of

ICMP Query Message.

By exploiting both this message enable a hacker to collect information as

much as possible before doing attack and prepare needed to strategy do attack to

meant host. The efforts can anticipate by perceiving and analysing package format

characteristic of datagram ICMP at protocol of TCP/IP with tool in the form of

sniffer software (Ethereal).
