  • Freebsd's Jail(2) Facility
    Lousy virtualization, Happy users: FreeBSD's jail(2) facility Poul-Henning Kamp [email protected] CHROOT(2) FreeBSD System Calls Manual CHROOT(2) NAME chroot -- change root directory LIBRARY Standard C Library (libc, -lc) SYNOPSIS #include <unistd.h> int chroot(const char *dirname); Calling chroot(2) in ftpd(1) implemented ”anonymous FTP” without the hazzle of file/pathname parsing and editing. ”anonymous FTP” became used as a tool to enhance network security. By inference, chroot(2) became seen as a security enhancing feature. ...The source were not strong in those. Exercise 1: List at least four ways to escape chroot(2). Then the Internet happened, ...and web-servers, ...and web-hosting Virtual hosts in Apache User get their own ”virtual apache” but do do not get your own machine. Also shared: Databases mailprograms PHP/Perl etc. Upgrading tools (PHP, mySQL etc) on virtual hosting machines is a nightmare. A really bad nightmare: Cust#1 needs mySQL version > N Cust#2 cannot use mySQL version <M (unless PHP version > K) Cust#3 does not answer telephone Cust#4 has new sysadmin Cust#5 is just about ready with new version Wanted: Lightweight virtualization Same kernel, but virtual filesystem and network address plus root limitations. Just like chroot(2) with IP numbers on top. Will pay cash. Close holes in chroot(2) Introduce ”jail” syscall + kernel struct Block jailed root in most suser(9) calls. Check ”if jail, same jail ?” in strategic places. Fiddle socket syscall arguments: INADDR_ANY -> jail.ip INADDR_LOOPBACK -> jail.ip Not part of jail(2): Resource restriction Hardware virtualization Covert channel prevention (the hard stuff) Total implementation: 350 changed source lines 400 new lines of code FreeBSD without jail usr Resources of various sorts / home var process process process process process process Kernel FreeBSD with jail usr Resources of various sorts / home var process process process process* process process Kernel error = priv_check_cred( cred, PRIV_VFS_LINK, SUSER_ALLOWJAIL); if (error) return (error); The unjailed part One jailed part of the system.

  • 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

  • Zero Vpn Download Pc Apple App Store Zero VPN Review
    zero vpn download pc Apple App Store Zero VPN Review. By forming a private network through a public internet connection, a Virtual Private Network (VPN) provides you online privacy to surf the internet. This is done by masking your IP address. There are many VPN services now available in the market for a price subscription as well as for free. Zero VPN is a completely free online security provider available only for Android devices. The app was developed by TNTAPP in the Netherlands. It gives you the freedom to visit the websites and social media networks that are restricted and blocked in your region. However, Zero VPN holds a lot of poor reviews compared to the rest in the market. The VPN is rated with 4.1 stars. Anyways, let us find out the truth behind this by experiencing it on our own. Keep reading. Warning: Zero VPN seems to either be a botnet or is running malicious code on users’ devices. You should not install Zero VPN on your device. You should instead choose a legitimate and proven VPN like ExpressVPN. Pros: No registration needed No visible DNS leaks. Cons: Privacy is at stake No customer support Many gray areas to doubt on No updates over a year No special features that stand out for the VIP version. Installation of Zero VPN. Zero VPN is compatible with Android, Windows, and Mac. It is disappointing that there is no IOS version available. Besides, you cannot install Zero VPN on Amazon Fire TV, or to a router. When installing in your phone, it is the usual routine that you follow to download in Android.

  • List of TCP and UDP Port Numbers from Wikipedia, the Free Encyclopedia
    List of TCP and UDP port numbers From Wikipedia, the free encyclopedia This is a list of Internet socket port numbers used by protocols of the transport layer of the Internet Protocol Suite for the establishment of host-to-host connectivity. Originally, port numbers were used by the Network Control Program (NCP) in the ARPANET for which two ports were required for half- duplex transmission. Later, the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full- duplex, bidirectional traffic. The even-numbered ports were not used, and this resulted in some even numbers in the well-known port number /etc/services, a service name range being unassigned. The Stream Control Transmission Protocol database file on Unix-like operating (SCTP) and the Datagram Congestion Control Protocol (DCCP) also systems.[1][2][3][4] use port numbers. They usually use port numbers that match the services of the corresponding TCP or UDP implementation, if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[5] However, many unofficial uses of both well-known and registered port numbers occur in practice. Contents 1 Table legend 2 Well-known ports 3 Registered ports 4 Dynamic, private or ephemeral ports 5 See also 6 References 7 External links Table legend Official: Port is registered with IANA for the application.[5] Unofficial: Port is not registered with IANA for the application. Multiple use: Multiple applications are known to use this port. Well-known ports The port numbers in the range from 0 to 1023 are the well-known ports or system ports.[6] They are used by system processes that provide widely used types of network services.
