Linux Operating System and Information Security - Essay Example

The paper "Linux Operating System and Information Security" is an excellent example of an essay on information technology. Proper configuration of directory and file permissions are significant in all systems. In the Linux operating system, it is equally important to ensure that information security is guaranteed. Though the Linux Operating System is secure by default, it is important that administrators verify that the directory and file permissions of the server are secure. Additionally, proper configuration of the directory and file permissions ensure that administrators share data in a safe manner (Lewis, 2013). 

The use of default or fewer restrictive permissions on files or directories poses several threats and attacks to the information contained on Linux servers. With the default settings, attacks that cause deletion of files or overwriting of files may readily occur. Different administrators may also create a symbolic link to any file, and this could cause the deletion of data. Additionally, there are certain files that may grant access and special privileges to the users when there are no restrictive permissions.
In an organization, it is imperative to create permission groups. First, the members of the organization must be categorized into three groups based on their permission of accessing directories and files. The groups will include the owner, group and all users. Each of the directories and groups must be assigned three basic permissions. The member who can have the permission to write files must be the administrators of the firm. Depending on the type of organizational information, members of the organization may be granted access to read and execute commands. In the organizational set-up, the formation of permission groups and assigning relevant permission types can guarantee the safety of organization files and directories. Read More
