sandbox allowing a process to view only a single sub-tree of the file system.” “In order for it to work properly, some common programs and libraries need to be copied or linked to the appropriate locations in the new directory tree.” (Haas) The term sandbox is a metaphor for the type of security that chroot jail uses. Once you put a program or utility into the jail, it only knows of what is contained in the cell, the rest of your system becomes invisible to it. It does this by changing the apparent

protection scheme that will provide controlled access to specific files in a system is not only an important but also a necessary task to ensure that the integrity as well as the availability of that file is maintained throughout. This paper is designed to put into perspective a protection scheme to facilitate the scenario where a system has 5000 user and 4990 of those users will need to have access to a particular file within the system. It will also provide clarity on Access control list (ACL’s) their

is a program that allows end users to access and use printers, files, and other commonly shared resources on the Internet. SAMBA allow two or more operating system to connect with to one another .SAMBA is based on the common client/server protocol of Server Message Block (SMB) and Common File System (Internet CIFS).

would the largest possible file be? Answer: The indirect block can hold 128 disk addresses. 1KB/8=128blocks 10 direct disk addresses, maximum file has 128+10=138 blocks.so each block is 1 KB the largest file could be 138 KB. 22. Explain how hard links and soft links differ with respective to i-node allocations. Soft link: soft link have different inodes numbers.Softlink contain only path of original file.if we remove softlink it will not affect anything but if file is removed then link become

naming of files; 1. Firstly to start organising and naming your files within your documents, you have to open up ‘my documents’ window.

hosting random files and pictures from the previous owner, it could also host nefarious files intended to access the companies network.

A Trojan virus is malicious code that is hidden in such a way as to obfuscate its intention, usually in the form of a legitimate program or file (Kaspersky, 2018). Once the program is introduced to a non-infected system, the payload of

System Level Scripting #2 This week’s critical thinking assignment explores the system-level scripting functionality of the Linux operating system. Documenting each step in the assignment will demonstrate how to use the awk and sed commands to display different sets of data from and file based on the commands used. The sed command will also be used to change the data within the test file. These steps will be discussed and illustrated with screenshots in the following paper. awk and sed After opening
