Transcription de la présentation

  1. Training Virus Computer

  2. Objective Training • Increase Virus Awareness. • Know practical ways to present computer viruses.

  3. Platform • Windows • Novell • DOS

  4. Delivery • Seminar & Discussion • Directed “Hands on”.

  5. Warning! • We are dealing with REAL computer virus in this training. • Our collection of viruses are approx. 75. • It will crash our computer!

  6. History & Statistics Computer Network Research Group Institut Teknologi Bandung

  7. Outline • Beberapa sejarah penting Virus. • Beberapa statistik penting penyebaran virus. • Summary.

  8. Early Viral Programs • Password Trojans. • Cookie.

  9. 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.

  10. 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.

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

  12. Virus Statistik • Berdasarkan laporan NCSA (National Computer Security Association). • Intel-based PC. • Site di Amerika Utara. • Industri & Pemerintah saja.

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

  14. 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

  15. Virus Penetration

  16. Word Macro infected over one third (36%) of survey site and was responsible for one-half (49%) of all virus encounters

  17. 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

  18. 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.

  19. 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.
