While comparing windows and linux each other lots of peoples have one thing in mind that linux is more secure against viruses.This could be the one from many reasons that linux is widely being used on servers but if we think about why linux is secure against viruses than windows.We will have lots of reasons in mind.In this post i am gonna list some reasons why linux is secure against viruses than windows.
1) User Privileges.
In linux no user is given administrative Privileges rather than root therefore linux doesn’t allow a normal user to write any system file.Only root user can install software and can edit system file so if you need to install any software or need to edit any configuration file you will have use su – command.
2) No Executables.
Like windows linux doesn’t support .exe files. Most of the viruses in windows are being spread with .exe files what happens you just double click on .exe file and virus,trojan or malware easily integrate itself with windows.
3) No Registry.
Registry is another place where viruses put their information so what happens even if you delete files infected with virus.It rewrites its information from registry and it is also too difficult to find where virus hides its information in registry.Linux uses configuration files rather than registry so another big hole for viruses is closed and as i mentioned in point 1 that linux doesn’t allow any normal user to edit system files.
4) No Internet Explorer (IE)
Internet Explorer (IE) which is installed in windows by default is another big hole for virus.It has been proved by many times by research that IE is has lots of vulnerabilities.Linux has Mozilla firefox browser installed by default which is the most secure browser and blocks most of viruses and trojans and doesn’t allow any website to install any software without your permission.
5) Linux is not soo common like windows.
Although developers of linux has improved it alot and has also worked to make it user friendly but still linux is unsuccessful to capture most of the desktop users.Most of the viruses are made for desktop users rather than servers because servers are monitored by system administrators and have security softwares,Hardware firewalls and much more to protect them against viruses.Because linux is not common like windows number of viruses created for linux is also minimum.
