  • Chrooting All Services in Linux
    LinuxFocus article number 225 http://linuxfocus.org Chrooting All Services in Linux by Mark Nielsen (homepage) About the author: Abstract: Mark works as an independent consultant Chrooted system services improve security by limiting damage that donating time to causes like someone who broke into the system can possibly do. GNUJobs.com, writing _________________ _________________ _________________ articles, writing free software, and working as a volunteer at eastmont.net. Introduction What is chroot? Chroot basically redefines the universe for a program. More accurately, it redefines the "ROOT" directory or "/" for a program or login session. Basically, everything outside of the directory you use chroot on doesn't exist as far a program or shell is concerned. Why is this useful? If someone breaks into your computer, they won't be able to see all the files on your system. Not being able to see your files limits the commands they can do and also doesn't give them the ability to exploit other files that are insecure. The only drawback is, I believe it doesn't stop them from looking at network connections and other stuff. Thus, you want to do a few more things which we won't get into in this article too much: Secure your networking ports. Have all services run as a service under a non-root account. In addition, have all services chrooted. Forward syslogs to another computer. Analyze logs files Analyze people trying to detect random ports on your computer Limit cpu and memory resources for a service. Activate account quotas. The reason why I consider chroot (with a non-root service) to be a line of defense is, if someone breaks in under a non-root account, and there are no files which they can use to break into root, then they can only limit damage to the area they break in.

  • Making Linux Protection Mechanisms Egalitarian with Userfs
    Making Linux Protection Mechanisms Egalitarian with UserFS Taesoo Kim and Nickolai Zeldovich MIT CSAIL ABSTRACT firewall rules, forcing applications to invent their own UserFS provides egalitarian OS protection mechanisms protection techniques like system call interposition [15], in Linux. UserFS allows any user—not just the system binary rewriting [30] or analysis [13, 45], or interposing administrator—to allocate Unix user IDs, to use chroot, on system accesses in a language runtime like Javascript. and to set up firewall rules in order to confine untrusted This paper presents the design of UserFS, a kernel code. One key idea in UserFS is representing user IDs as framework that allows any application to use traditional files in a /proc-like file system, thus allowing applica- OS protection mechanisms on a Unix system, and a proto- tions to manage user IDs like any other files, by setting type implementation of UserFS for Linux. UserFS makes permissions and passing file descriptors over Unix do- protection mechanisms egalitarian, so that any user—not main sockets. UserFS addresses several challenges in just the system administrator—can allocate new user IDs, making user IDs egalitarian, including accountability, re- set up firewall rules, and isolate processes using chroot. source allocation, persistence, and UID reuse.

  • Sandboxing 2 Change Root: Chroot()
    Sandboxing 2 Change Root: chroot() Oldest Unix isolation mechanism Make a process believe that some subtree is the entire file system File outside of this subtree simply don’t exist Sounds good, but. Sandboxing 2 2 / 47 Chroot Sandboxing 2 3 / 47 Limitations of Chroot Only root can invoke it. (Why?) Setting up minimum necessary environment can be painful The program to execute generally needs to live within the subtree, where it’s exposed Still vulnerable to root compromise Doesn’t protect network identity Sandboxing 2 4 / 47 Root versus Chroot Suppose an ordinary user could use chroot() Create a link to the sudo command Create /etc and /etc/passwd with a known root password Create links to any files you want to read or write Besides, root can escape from chroot() Sandboxing 2 5 / 47 Escaping Chroot What is the current directory? If it’s not under the chroot() tree, try chdir("../../..") Better escape: create device files On Unix, all (non-network) devices have filenames Even physical memory has a filename Create a physical memory device, open it, and change the kernel data structures to remove the restriction Create a disk device, and mount a file system on it. Then chroot() to the real root (On Unix systems, disks other than the root file system are “mounted” as a subtree somewhere) Sandboxing 2 6 / 47 Trying Chroot # mkdir /usr/sandbox /usr/sandbox/bin # cp /bin/sh /usr/sandbox/bin/sh # chroot /usr/sandbox /bin/sh chroot: /bin/sh: Exec format error # mkdir /usr/sandbox/libexec # cp /libexec/ld.elf_so /usr/sandbox/libexec # chroot /usr/sandbox

  • The Oldest Rivalry in Computing Forget Apple Vs
    Follow us on Twitter for more great Slate stories! Follow @slate BITWISE DECODING THE TECH WORLD. MAY 9 2014 9:57 AM The Oldest Rivalry in Computing Forget Apple vs. Google. Emacs and Vi have been battling for text-editor supremacy among programmers for 40 years. By David Auerbach An early Emacs manual cover from 1981. Courtesy of GNU Emacs n a world where both software and hardware frequently become obsolete right I on release, two rival programs can stake a claim to being among the longest-lived applications of all time. Both programs are about to enter their fifth decades. Both programs are text editors, for inputting and editing code, data files, raw HTML Web pages, and anything else. And they are mortal enemies. Their names are Emacs and Vi (styled by programmers as “vi”). These editors are legendary and ancient, no exaggeration. Both date back to at least 1976, making them older than the vast majority of people currently using them. Both programs are text editors, which means they are not WYSIWYG (what you see is what you get)—unlike, say, word processors like Microsoft Word, they do not format your words onscreen. Programming is very different from word processing, and the basic goal of Emacs and Vi—fast editing of source code (and any other text files)—has yet to become obsolete. Both have been in ongoing development for almost 40 years. These two wizened programs are as close to equally matched enemies as any two programs have ever been. If you know a programmer who uses one of them, there’s a good chance that she hates the other.

  • Unix Security Overview: 1
    CIS/CSE 643: Computer Security (Syracuse University) Unix Security Overview: 1 Unix Security Overview 1 User and Group • Users – root: super user (uid = 0) – daemon: handle networks. – nobody: owns no files, used as a default user for unprivileged operations. ∗ Web browser can run with this mode. – User needs to log in with a password. The encrypted password is stored in /etc/shadow. – User information is stored in /etc/passwd, the place that was used to store passwords (not anymore). The following is an example of an entry in this file. john:x:30000:40000:John Doe:/home/john:/usr/local/bin/tcsh • Groups – Sometimes, it is more convenient if we can assign permissions to a group of users, i.e. we would like to assign permission based on groups. – A user has a primary group (listed in /etc/passwd), and this is the one associated to the files the user created. – Any user can be a member of multiple groups. – Group member information is stored in /etc/group % groups uid (display the groups that uid belongs to) – For systems that use NIS (Network Information Service), originally called Yellow Page (YP), we can get the group information using the command ypcat. % ypcat group (can display all the groups and their members) 2 File Permissions • File Permissions – The meaning of the permission bits in Unix. ∗ Owner (u), Group (g), and Others (o). ∗ Readable (r), Writable (w), and Executable (x). ∗ Example: -rwxrwxrwx (777) • Permissions on Directories: – r: the directory can be listed. – w: can create/delete a file or a directory within the directory.
