Comparative presentation of applications on Linux and Windows

1
Comparative presentation of applications on Linux
and Windows
2
Program instaltion

• How are programs installed?
• What is a source code of an application?
• What is a binary code of an application?
• Installing applications under Windows
• Installing applications under Linux
• ./configure
• make
• make install

3
Criteria for comparison

• Functionality
• Prize of the product (application)
• Security and stability
• Possibility for customizing
• Possibility for upgrade

4
The Value of an application

• Collecting information for choosing an
  application
• Financial expanses
• Getting accustomed, adjousting the user interface
  
• time as a valuable resource
• Possibility for customizing and adjusting
  according to the current and future needs of the
  company
• Transparent interface for other applications

5
Security aspect

• Windows dominates the market, therefore its
  cracked more often?
• The average time that takes an unpatched Windows
  XP to be compromised once connected to the
  Internet is 16 minutes
• ..... It takes less time than to download the
  patches for it ?
• Time that elapses from discovering a flaw or
  exploit to the time the patch is provided

6
Security aspect

• Easy manipulation and installation doesnt come
  free
• The applications should communicate between each
  other through standard protocols
• Two layers of protection
• Operating system
• Application layer

7
Security aspect

• Buffer overflow
• What can an attacker accomplish?
• Protecting the separate segments that a process
  uses

8
Bad security design architecture of the Windows OS

• Windows hasnt yet evolved completely to a
  multi-user operating system
• Windows is monolitic, not modular
• It depends too mush on RPC
• Windows is very much focused and integrated with
  its graphical interface

9
Good security design architecture of the Linux OS

• It has been a multi-user operating system concept
  since the very beginning
• Linux is mostly modular design
• Linux doesnt depend on RPC
• Non-graphical user interface
• Ideal for remote administration

10
Stability aspect

• 50 most stable web servers
• 47 on Apache
• None on IIS
• 50 are on an BSD platform
• BSD, Linux, Solaris, HP-UX .. Windows ???

11
Stability aspect

• Unofficial numbers
• www.microsoft.com
• IIS web server
• Average uptime 59 days
• Maximum uptime 111 days
• www.linux.com
• Apache web server
• Average uptime 348 days
• Maximum uptime 490 days

12
Comparison of frequently used applications

• Office ?????????
• Windows Linux
• MS Office Openoffice.org
• KOffice
• Gnome Office
• Dia, Kivio, Kpdf
• Project Management
• All of the Linux Office suits include
  applications for word processing, spreadsheets,
  presentations, database, modeling and
  mathematical functions.

13
Comparison of frequently used applications

• Multimedia applications
• Windows Linux
• Win Media Player Xine, Kaffeine, Gxine

• Win Explorer Konqueror, Nautilus, Thunar
• System monitor Gkrellm, top, sys monitor apps
• Notepad, wordpad Kwrite, Kate, Gedit
• Commercial Antivirus Clamav
• Commercial Firewall Netfilter, iptables,
  ipchains,
• ipfw, pf
• Tottal commander Midnight commander

16
Open source server software

• Web Server, Proxy
• Apache, Lightttpd, Zope, proxy Squid
• Content management system
• Joomla, Drupal, Sugarcrm, Wordpress
• E-mail server
• Postfix, Qmail, Sendmail, Qpopper, Squiremail,
  Spamassasin, Clamav
• Database Server
• MySQL, PostgreSQL
• DNS ??????
• BIND

17
Compatibility between the two operating systems

• Executing Linux applications on Windows
• Executing Windows applications on Linux
• WINE Windows emulator
• Which applications can we use under Windows and
  Linux?
• Which documents can we manage both under Windows
  and Linux?
• Which applications work better on Linux?

18
Possibilities for upgrading the FOSS software

• Possibilities that the source code offers
• Communication between applicatoins, associating
  multiple applications
• The upgrade is an transparent process
• Discovering potential flaws and exploits in the
  code
• You are sure in what You have
• Who guaranties for the free FOSS software? If
  something goes wrong who is responsible?
