Why Linux is more secure?

Why Linux is more secure?




Linux is free and open source code OS  distribution built around Linux Kernel. It's more secure as compared to other OS. In this post, we talk about which factor makes Linux more secure than other others.


1.Account Privileges


In Linux, the users are given limited access, that the main reason, which makes Linux more secure. If a virus enters in a Linux system it can only be damaged the locate files and folders. So the system-wide damage is safe, we compare Linux to other OS in Account privileges.
Other OS   users get the authentication to full access on the system, by defaults. In this condition, if the virus enters into your system, they can easily access the crucial part of our system.



2. Auditing System



In Linux, all of your task and system calls can be seen in the log file. The benefit of these log file is that if anyone tries to break the security of the system folders and files his security breaches can be generated in the log event file and it can also be reviewed by the system administrator.

 Tries to break the permission of any files, folders, The failed login attempts, and other security-related events can also be recorded on the disk. These types of event can be seen in the log file.


3. SELinux in Linux



Linux has some protocols and packages that windows doesn't have and it makes windows less secure

One of its most important is SELinux security (S- security E- enhanced Linux). Which gives administrators and added users have more power over file access.
Why LInux is more secure?


Selinux is a particular set of programs, libraries, and dependencies.
It provides a MAC (Mandatory Access Control) system built into the Linux kernel. In Linux Root is the superuser  Root has power to full access of the system,  
In  General, when a file is created by the user, the user will have read, write permission and also have permission to change the ownership and group ownership of the file.
When security problem cones related to file access, To avoid this
SELinux plays a vital role in this case.


4. IPtables in Linux OS



Iptables used to Control Network Traffic. It acts as a packet filter and firewall that allows users to configure specific rules that will be enforced by the kernel netfilter framework.

IPtables control the incoming traffic from the outside and examines traffic based on protocol and other criteria.


5. PAM (Pluggable Authentication Modules)


PAM makes our Linux system more secure. PAM handles the authentication process of application in your system. 
It divides the authentication task into four management groups, which provide more security of your authentication task.
A.  Password Management -- This management is used for changing user passwords


B. Session Management --   Its user for managing and configuring user session, from login to Log out



C. Account Management --   It provides verification related services, such that it may check user is allowed to log in at that time.



D. Authentication Management --  It can authenticate a user and verifies or requests the validity of the password.

It can also set up user credentials. Such as group membership or Kerberos.



6. Fewer Users



The number of Linux users are less in a comparison with Windows, From it, Linux gets a plus point, less virus will strive to hit their system to gain access to important data.
