  24. 28. Web Server lain?
  25. 29. Yankee Group/Sunbelt 2006 Server Reliability Survey Results All of the major server operating system platforms have achieved a high degree of reliability, though Unix-based servers still record the least amount of annual downtime.
  26. 30. Linux vs.Windows: Total Cost of Ownership (TCO) Survey (Yankee Group) The survey emphasized that businesses continue to expand the ways in which they utilize Linux. Over 50% of corporations now utilize Linux for a variety of functions including: Web server, Email server and specialized application server. Perhaps the most startling survey revelation was the fact that over 50% of the respondents said they had performed a thorough TCO analysis. But when asked to calculate their specific Linux and Windows capital expenditure and maintenance costs, 75% on average, could not answer explicit questions.
  27. 31. Security Issues Survey Software Security Summit Conference (La Jolla, California, BZ Research polled 6,344 software development managers) Lingkup Server: Some 58% rated Windows Server very insecure or insecure versus 13% for Linux. Sun Solaris fared best, with only 6% rating the operating system very insecure or insecure. On the positive side, some 74% of respondents rated Linux secure or very secure versus only 38% for Windows Server. Sun Solaris was rated secure or very secure by 66%. Lingkup Aplikasi: Asked about the security of operating systems against application-related hacks and exploits, Windows Server was again rated least secure. Some 58% of respondents rated Windows Server as very insecure or insecure versus 18% for Linux. On the other hand, Linux was deemed secure or very secure by 66% of respondents versus only 30% for Windows Server.
  28. 32. Perbandingan Keamanan Open Source vs Proprietary Perbandingan keamanan open source dan proprietary pada delapan kategori: open source was the clear winner in four of the categories: desktop/ client operating systems (44% to 17%); Web servers (43% to 14%); server operating systems (38% to 22%); and components and libraries (34% to 18%).
  29. 34. Hacker dan Cracker
  30. 35. Hacker <ul><ul><li>...most having to do with technical adeptness </li></ul></ul><ul><ul><li>and a delight in solving problems </li></ul></ul><ul><ul><li>and overcoming limits. </li></ul></ul><ul><ul><li>- Eric Steven Raymond (ESR) dalam “ How To Become A Hacker ” </li></ul></ul>
  31. 36. Hacking <ul><ul><li>Software, Hardware, ... </li></ul></ul>
  32. 37. Cracker <ul><ul><li>These are people (mainly adolescent males) who get a kick out of breaking into computers and phreaking the phone system. </li></ul></ul><ul><ul><li>- Eric Steven Raymond (ESR) dalam “ How To Become A Hacker ” </li></ul></ul><ul><ul><li>One who breaks security on a system. </li></ul></ul><ul><ul><li>- From Jargon File </li></ul></ul>
  33. 38. Cracking <ul><ul><li>Software : Serial Number, Trial, “Customizing”, ... </li></ul></ul><ul><ul><li>Sistem : Vulnerability scanning, penetration, Denial of Service (DoS) Attack, ... </li></ul></ul>
  34. 39. Hacker vs Cracker <ul><ul><li>The basic difference is this: hackers build things, crackers break them. </li></ul></ul><ul><ul><li>- ESR dalam “How to Become A Hacker” </li></ul></ul>
