Ubuntu repository contains multitude of tools - an important tool for securing networks and network administarsi. Security tools - security tool presented in this arikel include network scanning, attack detection, virus detection and much more.
Wireshark - network traffic analyzer
Wireshark is a network traffic analyzer, or "sniffer", u lo Unidx operating system and Unix variants. Sniffer is a tool for capturing packet-packet that shot out of the cable, Wireshark protocol decode many (very many protocols supported). Installing Wireshark on Ubuntu as follows: sudo aptitude install wireshark
Nessus - Remote Network Security Auditor
Nessus vulnerability scanner is the world-class scanner is still active, carrying high speeddicovery features, configuration auditing, asset profiling, sensitive data discovery and analysis vilnerabilitu, Installing Nessus on Ubuntu is as follows: sudo aptitude install nessus
Nmap - The Network Mapper
Nmap ("Network Mapper") is a free and open source utility for network exploration or security auditing. Many system administrators and network administrators find this tool useful for nerwork Juka inventory, managing service upgrade schedules, and monitoring host or service uptime.
Nmap uses raw IP packets with a unique way to determine whether the host - the host on the network or not, the service (application name and version) in the host operating systems (and OS versions) are used, the type of packet filters / firewalls are in use, and dozens of other capabilities. It was designed to rapidly scan large networks, but works fine on a single host. Nmap runs on many operating systems. Available console versions plus graphics. Installing Nmap on Ubuntu as follows: sudo aptitude install nmap. If you want fronted nmap, install the following package: sudo aptitude install Zenmap.
Etherape - graphical network monitor derivatives etherman
EtherApe is a graphical network monitor for Unix scaled from etherman. Megusung features link layer, ip and TCP modes, it displays network activity graphically. Hosts and links change according to traffic. Protocols displayed colors - iridescent. This tool also supports Ethernet, FDDI, Token Ring, ISDN, PPP and SLIP devices. He was able to filter the traffic to be shown, and can read traffic from a file as well directly from the network. Etherape installation on Ubuntu is as follows: sudo aptitude install etherape
Kismet - Wireless 802.11b monitoring tool
Kismet is an 802.11 layer 2 wireless network detector, sniffer, and intrusion derection system. Kismet works on any wireless card which supports raw monitoring (rfmon) mode, and can sniff traffic 802.11b, 802.11a, and 802.11g.
Kismet identifies networks by passively collecting packets and detecting standard melauli hidden network and detect the presence of non-beaconing networks via data traffic. Isntalasi Kismet in Ubuntu is: sudo aptitude install kismet
Chkrootkit - Checks the presence of rootkits on the local system
Chkrootkit identifies whether the target computer in rootkit infection or not. Some rootkit chkrootkit is recognized
1. Irk2, Irk4, Irk5, Irk6 (and some variants)
2. Solaris rootkit;
3. FreeBSD rootkit;
4. T0M (including variants)
5. Ambient's Rootkit for Linux (ARK);
6. Ramen Worm;
7. rh [67]-shaper;
8. RSHA;
9. Romanian Rootkits;
10. RK17;
11. Lion Worm;
12. Adore Worm.
Chkrootkit installation on Ubuntu is as follows: sudo aptitude install chkrootkit.
Rkhunter - rootkit, back-door, snifer and exploit scanner.
Rootkit Hunter scans systems from attack rootkit, backdoor, sniffer and exploit. He can check the MD5 hash changes, files - files are commonly created by rootkits, file - the file executable permissions dile odd, string - suspicious strings in kernel modules, and files - tersembuyi files in the system directory. Dissamping itum he can both scan on the file. Using rkhunter alone does not guarantee the system completely - completely safe. Therefore you are recommended to run additional tests called chkrootkit. Installing rkhunter in Ubuntu is as follows: sudo aptitude install rkhunter
Tiger - Report system security vulnerabilities
TIGER, or 'tiger' scripts, is a set of Bourne shell scripts, C programs and data files used perform security auditing on UNIX systems. TIGER has one primary goal: report ways - ways 'root' can be infiltrated. Tiger on Debian on Arm new checking system specifically for Debian distributions. A check md5sums file - the file is installed, the location of files that are not part package, security checks and analysis processes eavesdropping (listening) local system. TIGER installation on Ubuntu is as follows: sudo aptitude install tiger
GnuPG - GNU privacy guard
GnuPG is GNU tool for communication and storasi safety data. It can be used to encrypt data and creating digital signatures. It contains advanced key management facility and supports the Open PGP standard Internet which is described in RFC2440. GnuPGP not wear patent algorithm so that it is not compatible with PGP2 because it uses IDEA (which is patented in the world). Installation in Ubuntu is as follows: sudo aptitude install gnupg
If you want gnupg GUI tool, try Seahorse (Gnome front end for GnuPG). Seahorse is a GNOME application for encryption key management, it is integrated into Nautilus, Gedit and other locations for encryption. Seahorse on the Ubuntu installation is as follows: sudo aptitude install seahorse
Nemesis - TCP / IP Packet Injection Suit
Nemesis is a command-line network packet crafting and injection utility for UNIX and Windows. Nemesis suited for testing Network Intusion Detection Systems, firewalls, IP stacks and a variety of other network tasks. As a command line utility basis. Nemesis is perfect for automation and scripting. Nemesis can create and inject packets ARP, DNS, ETHERNET, ICMO, IGMP, IP, OSPF, RIP, TCP and UDP. Using the IP and the Ethernet injection modes, almost all packages can be created and in the injection. Installing Ubuntu nemesis in the following: sudo aptitude install nemesis.
