Best Linux hacking OS

Looking for  best Linux to learn hacking ? Whether you want to pursue a career in Information Security or you are already working as a security professional or if you are just interested in this specific field of knowledge, a decent Linux distro that suits your purpose is a must. There are countless Linux distros for various purposes. Some are designed for specific tasks in mind and others are for different interfaces. Best Linux hacking distributions I have basically listed out various Linux distributions focusing on security. These Linux distros provide various tools that are needed for assessing networking security and other similar tasks. List is in no particular order. 1.  Kali Linux Kali Linux is the most widely known Linux distro for ethical hacking and penetration testing. Kali Linux was developed by Offensive Security taking on the mantle of  BackTrack . Kali Linux Kali Linux is based on Debian. It comes with a large amount of penetration testi...

Hacker Tools Top Ten

Our Recommended Pentesting Tools and Hacking Software For 2018 Nmap (Network Mapper) Used to Scan Ports and Map Networks - and a whole bunch more! Cost of Tool:  Free Nmap is an abbreviation of  ‘Network Mapper’,  and it’s very well known free open source hackers tool. Nmap is mainly used for network discovery and security auditing. Literally, thousands of system admins all around the world will use nmap for network inventory, check for open ports, manage service upgrade schedules, and monitor host or service uptime. Nmap, as a tool uses raw IP packets in creative ways to determine what hosts are available on the network, what services (application name and version) those hosts are providing information about, what operating systems (fingerprinting) and what type and version of packet filters/ firewalls are being used by the target. There are dozens of benefits of using nmap, one of which is that fact that the admin user is able to determine whether the net...

Different Types of Router Memory

ROM ROM is read-only memory available on a router's processor board. The initial bootstrap software that runs on a Cisco router is usually stored in ROM. ROM also maintains instructions for  Power-on Self Test (POST)  diagnostics. For ROM Software upgrades, the pluggable chips on the motherboard should be replaced. Flash Memory Flash memory is an Electronically Erasable and Re-Programmable memory chip. The Flash memory contains the full Operating System Image (IOS, Internetwork Operating S

IPv6

What is IPv6? IPv6 is the newest version of the IP protocol. IPv6 was developed to overcome many deficiencies of IPv4, most notably the problem of IPv4 address exhaustion. Unlike IPv4,

IOS basic commands

Hostname command The  hostname  command is used to configure a device hostname. Because this command changes a device configuration, the command must be entered in the global configuration

IOS command modes

User EXEC mode commands Initially, a user logs into the User Exec mode. This is the mode with the least number of commands. You can get a list of all available commands by typing the character “?”.

HTTP & HTTPS

HTTP (Hypertext Transfer Protocol) HTTP is an client-server protocol that allows clients to request web pages from web servers. It is an application level protocol widely used on the Internet. Clients are usually web browsers. When a user wants to access a web page, a browser sends an HTTP Request

FTP & TFTP

FTP (File Transfer Protocol) FTP is a network protocol used to transfer files from one computer to another over a TCP network. Like Telnet, it uses a client-network arhitecture, which means that a user has to have an FTP client installed to access an FTP server running on the remote machine. After

Telnet & SSH

Telnet Telnet is a network protocol that allows a user to communicate with a remote device. It is a virtual terminal protocol used mostly by network administrators to remotely access and manage devices. Administrator can access the device by “telnetting” to the IP address or hostname of a remote device.

DHCP & DNS

DHCP (Dynamic Host Configuration Protocol) DHCP is a network protocol that is used to assign various network parameters to a device. This greatly simplifies administration, since there is no need to assign static network parameters for each device separately. DHCP is a client-server protocol. A client is a device

ARP

ARP (Address Resolution Protocol) is a network protocol used to find out the hardware (MAC) address of a device from an IP address. It is used when a device wants to communicate with some other device on a local network (for example on an Ethernet network that requires physical addresses to be known before sending packets). The sending

TCP/IP suite of protocols

The TCP/IP suite is a set of protocols used on computer networks today (most notably on the Internet). It provides an end-to-end connectivity by specifying how data should be packetized, addressed, transmitted, routed and received on a TCP/IP network. Th

Subnet mask

An IP address is divided into two parts: network and host parts. For example, an IP class A address consists of 8 bits identifying the network and 24 bits identifying the host. This is because the default subnet mask for a class A IP address is 8 bits long. (or, written in dotted decimal

Classes of IP addresses

TCP/IP defines five classes of IP addresses: class A, B, C, D, and E. Each class has a range of valid IP addresses. The value of the first octet determines the class. IP addresses

Cisco three-layer hierarchical model

Because networks can be extremely complicated, with multiple protocols and diverse technologies, Cisco has developed a layered hierarchical model for designing a reliable network infrastructure. This three-layer model helps you design, implement, and maintain a scalable

Network devices

Hubs   A hub serves as a central point to which all of the hosts in a network connect to. It is an OSI layer 1 device. It receives a signal from one port and sends it out to all other ports.

Unicast, multicast, and broadcast addresses

There are three types of Ethernet addresses: unicast addresses  – represent a single LAN interface. A unicast frame will be sent to a specific device, not to a group of devices on the LAN.

MAC & IP addresses

MAC address A Media Access Control (MAC) address is a 48-bit address that is used for communication between two hosts in an Ethernet environment. It is a hardware address, which means that it is stored in the firmware of the network card.
