Outline

Beberapa sejarah penting Virus. Beberapa statistik penting penyebaran virus. Summary.


Early Viral Programs

Password Trojans. Cookie.


Concept of Computer Virus

Dr. Fred Cohen 3 November 1983 Design a computer program that could modify

other programs to include a possibly evolved copy of itself.

This evolved copy would then modify other programs and thus continue the propagation and evolution.

The program could easily be spread by unknowing users throughout a computer system or network.


Computer Virus

Dr. Cohen's definition of a computer virus as "a program that can 'infect' other programs by modifying them to include a ... version of itself" is generally accepted as a standard.


Example Viruses

Lehigh Virus (COMMAND.COM) Jerusalem Virus (COM & EXE) Friday the 13th Brain Den Zuk


Virus Statistik

Berdasarkan laporan NCSA (National Computer Security Association).

Intel-based PC. Site di Amerika Utara. Industri & Pemerintah saja.


Executive Summary

Rate encounter one in 100 PCs per month. Common virus: Form (boot-track). Sejak Fall 1995: Word concept.


Bottom Line

Protect by simply using anti-virus software and by keeping the software reasonably up-to-date.

The effect of "herd immunity" would nearly eliminate the world-wide computer virus problem


Virus Penetration

Second half of 1995 71%

First half of 1995 63%

All of 1994 21%


Word Macro infected over onethird (36%) of survey site and wasresponsible for one-half (49%) of

all virus encounters


Consequence Virus Attack

29% of sites which experienced virus incidents: Servers were down for an average of 5.8

hours. Complete recovery took an average of 44

hours. Ten person-days of work. An average $8,100 in self-proclaimed costs


Anti Virus at Client / PC

97% used anti-virus products. 60% have some form of protection. 25% of desktop PCs are protected by a virus

scanning policy alone. 27% have periodic protection (automatic

scanning for viruses) 33% automatically scan for viruses as a

background task.


Anti Virus at Server

85% used anti-virus products on servers. 64% f all servers appear to have some

protection installed. 28% of servers are protected by periodically

scanning for viruses. 36% claim to use a full-time, background

task.
