This system poses a problem in that each software stack has to be built for each different distribution. Flatpak and Snap packages solve some of these issues by providing distribution-agnostic packages that install in sandboxes."},{"@type":"Syllabus","name":"What is a file?","timeRequired":"PT4M59S","description":"In Unix, everything is a file. Linux follows this philosophy. In this video, learn how to identify different types of devices that appear to be files such as character files and device files."},{"@type":"Syllabus","name":"Get information about files","timeRequired":"PT5M28S","description":"All Linux files have metadata associated with them. It's important to know important attributes about your files such as the file's type, which user and group can access it, and how big it is. Using ls, file, and stat gives you this information as well as when the file was accessed last and what permissions it will have when it runs."},{"@type":"Syllabus","name":"About extended attributes","timeRequired":"PT3M54S","description":"Extended file attributes allow administrators to add SELinux security context, access control lists, and special flags to make files immutable or even append-only. These attributes help administrators create secure Linux systems by adding to the Linux discretionary access control system as well as adding a mandatory access control system layered upon it."},{"@type":"Syllabus","name":"Get extended attributes","timeRequired":"PT4M14S","description":"The first step to knowing your operating system is gathering information about your files. Some standard tools will gather information on file attributes but gathering information on extended attributes will require commands specifically designed for the purpose."},{"@type":"Syllabus","name":"Linux permissions overview","timeRequired":"PT1M52S","description":"The Linux permission system has proven itself for the last four decades. It allows administrators to set read, write, and execute permissions for user owners, group owners, and everyone else. It also supports basic inheritance through the group owner. The Linux permission system has its faults though which is covered in this video."},{"@type":"Syllabus","name":"File and directory modes","timeRequired":"PT1M16S","description":"The Linux permission system isn't complex. It uses three attributes for three different permission positions. Knowing how to read, write, and execute works on files is important. These same permissions are used for directories too which provides the ability to enter directories, create new files, and list directory contents."},{"@type":"Syllabus","name":"File ownership","timeRequired":"PT3M14S","description":"Linux files are owned by one user owner and one group owner but no more. Using chown you can change the user and group ownership of a file or directory. File and directory ownership can also be set recursively if necessary. Users and groups have to exist before making files owned by them. Their existence can be verified by viewing /etc/passwd and /etc/group."},{"@type":"Syllabus","name":"Permissions using numeric method","timeRequired":"PT3M2S","description":"There are two different notations for setting permissions in Linux, numeric and symbolic. In numeric mode read has a value of 4, write is equal to 2, and execute is 1. To set permission using numeric mode a user will add up the values and assign the result to the user owner, group owner, and other using chmod."},{"@type":"Syllabus","name":"Permissions using symbolic method","timeRequired":"PT4M44S","description":"Setting permissions using symbolic notation has some advantages over numeric including the ability to add or subtract permissions. Another advantage may be that there's no math involved in setting permissions, a user would choose which flags to set r for read, w for write, and x for execute and then assign them to the file using chmod. Symbolic mode, however, requires more typing on the command line."},{"@type":"Syllabus","name":"Initial permissions using umask","timeRequired":"PT4M30S","description":"When files are created they automatically have permissions applied based on a default configuration setting called umask. Calculating the umask may seem inconsistent but as long as you know that maximum initial permissions on files will never have the execute bit set it makes more sense. Subtract the umask from the maximum initial permissions and you have the default permissions."},{"@type":"Syllabus","name":"Special file bits: SUID and SGID","timeRequired":"PT4M59S","description":"Linux permissions support an extra position for special bits. These special bits provide privilege escalation to the user owner or group owner for executable files. This allows normal users to elevate privileges without configuring complex services. Note, that these users are not prompted for any password. As such, files with SUID and SGID bits set can be dangerous. You can locate these files using the find command."},{"@type":"Syllabus","name":"Special directory bits: SGID and Sticky","timeRequired":"PT5M53S","description":"Special directory bits in Linux add group owner inheritance as well as the sticky bit which keeps users from deleting or renaming files that don't belong to them. SGID bit is responsible for creating the only inheritance in standard Linux permissions. Any file created inside an SGID directory will inherit the group owner of the parent directory."},{"@type":"Syllabus","name":"Access control lists overview","timeRequired":"PT3M32S","description":"Standard Linux permissions have some serious limitations such as files and directories can only belong to one user and one group. Permissions can only be set for the user, group, or everyone else. Access control lists remedy this situation by providing a user to add permissions to as many users and groups as necessary."},{"@type":"Syllabus","name":"Read access control lists","timeRequired":"PT3M33S","description":"Because ACLs are layered upon standard permissions you can't use standard tools to view them. To view ACLs you will need to use getfacl. You can also view standard Linux permissions with getfacl which shows standard permissions in a more readable manner than ls -l. You can also use getfacl to view all ACLs in the entire OS. This of course can be redirected to a file."},{"@type":"Syllabus","name":"Set access control lists","timeRequired":"PT5M40S","description":"Setting ACLs is quite easy using setfacl. The syntax is longer for setfacl but the job is easier. There's no real strategy for setting ACL other than just giving the users the permissions they need. Permissions can be granted to multiple users as well as multiple groups. ACLs can also be set recursively using the -R option."},{"@type":"Syllabus","name":"Configure inheritance with default access control lists","timeRequired":"PT4M1S","description":"Inheritance in standard permissions is fairly minimal in that files can only inherit the group owner and not permissions. Access control lists add default ACLs which are permissions that will be inherited by any future files or directories. Default ACLs work in addition to regular ACLs. A regular ACL grants access to the directory itself and a default ACL grants access to any newly created files and directories inside."},{"@type":"Syllabus","name":"Delete access control lists","timeRequired":"PT4M13S","description":"Due to the added power and complexity of ACLs, you have multiple ways of deleting ACLs. You can specify an ACL to delete which can be either a regular ACL or a default ACL. You can also delete all default ACLs or even delete all ACLs on the file including regular and default ACLs.
