Hacking operating system

Linux is the operating system which is most useful software that supports and will be helpful to identify the passwords and uses in detecting interruption there are many software tools are utilized for the hacking and security tools are used for the Linux. The tools which are using in this are not harmful tools this is especially used to protect.

John the ripper: John the ripper is nothing but password hacking software technique which is usually used to develop for the UNIX operating system. This the most significant process which is used for password testing as it joins all password crackers into single package and the auto detects password hash types which involves the customizable cracker (Ryan, David R. Mirza Ahmad, 2002). It can be run among the different encrypted password methods which involves various crypt password hash forms where usually found on the different UNIX operating systems that is based on the DES, MD5 etc, Kerberos AFS and windows like XP, 200etc.Generally passwords are placed in the LDAP and other tools. Various types of components are used to expand the capability and for involving the MD4 related password hashes. The other one is the NMAP; Nmap is the used to protect the network. It is especially used to identify the network related services on the computer network by generating the map of the network. Nmap is having the ability to identify the services on the computer network instead of this it never advertises its service detection protocol (James turnbull, 2005). However the Nmap can collect many details regarding the remote computers. This will involve the operating system, and uptimes etc are the software products that are used to execute the service, and are used to involve on the local area networks and also on the dealer of the remote network card. Nmap can be run on the linux. Linux is the most important operating system and the windows are the second most important operating system. The other operating system used is Nessus, this software is used to scan the virus. The main aim of this software is used to identify the virus on the tested system such as; the virus will permit the data on to the network (Mark Carey, Russ Rogers, Paul Criscuolo and mike Petruzzi, 2008). Default passwords are utilized on the network accounts. This software is also called as the external tool which is used to launch the attack. By making use of the mangled packets rejection of the service among the TCP/IP can be done. Nessus the best software used to scan the virus. Many organizations through out the world are using this software. The check Rootkit is the normal program which helps the administrator to check their system for the known rootkits ( James Turnbull, 2005). This program is the shell script by using the LINUX tools similar to the strings and the grep commands to seek out to carry out the core programs for the signatures with the executed process status command to look for inconsistency. This program alternatively use own commands to run. This tool will permit check rootkit to get confident the commands upon which it depend a bit more.
