Ethical Hacking - Reconnaissance

Information Gathering and getting to know the target systems is the first process in ethical hacking. Reconnaissance is a set of processes and techniques (Footprinting, Scanning & Enumeration) used to covertly discover and collect information about a target system.
During reconnaissance, an ethical hacker attempts to gather as much information about a target system as possible, following the seven steps listed below −

Gather initial information
Determine the network range
Identify active machines
Discover open ports and access points
Fingerprint the operating system
Uncover services on ports
Map the network

We will discuss in detail all these steps in the subsequent chapters of this tutorial. Reconnaissance takes place in two parts − Active Reconnaissance and Passive Reconnaissance.

Active Reconnaissance

In this process, you will directly interact with the computer system to gain information. This information can be relevant and accurate. But there is a risk of getting detected if you are planning active reconnaissance without permission. If you are detected, then system admin can take severe action against you and trail your subsequent activities.

Passive Reconnaissance

In this process, you will not be directly connected to a computer system. This process is used to gather essential information without ever interacting with the target systems.

IMPORTANCE AND ADVANTAGES OF SIWES

STUDENTS INDUSTRIAL WORK EXPERIENCE SCHEME (SIWES) The Industrial Training/Students Industrial Work Experience Scheme, IT/SIWES is a new Directorate under the Vice-Chancellor’s Office. It was established on 20th April, 2012 The Students Industrial Work Experience Scheme (SIWES) is a skills training programme designed to expose and prepare students of universities and other tertiary institutions for the Industrial Work situation they are likely to meet after graduation. It is also a planned and structured programme based on stated and specific career objectives which are geared towards developing the occupational competencies of participants (Mafe, 2009). Consequently, the SIWES programme is a compulsory graduation requirement for all Nigerian university students offering certain courses. The Students Industrial Work Experience Scheme (SIWES), is the accepted training programme, which

How to Reset HP Elitebook 8460p BIOS/Administrator Password

Have you forgotten HP Elitebook 8460p password , bios or administrator account password? How to do if both of them lost? It seems hard though there may be lots of ways that can solve it. But if we talk about it separately, such as in two parts, HP elitebook password reset would be not so difficult. Part 1: Reset HP Elitebook 8460p BIOS password Part 2: HP Elitebook 8460p Administrator password recovery Part 1: How to Reset Forgotten HP Elitebook BIOS Password? Generally, there are two ways to reset forgotten BIOS password . One is forcing BIOS/CMOS to reset itself to its stored defaults by removing all power from it. The other is to use a program to either locate or identify the password, and reveal it to you or erasing the password clearly. And the most easiest and convenient method for erasing dynamic BIOS/CMOS settings is to remove battery directly from the motherboard. However, it applies to most motherboards besides HP Elitebook BIOS. Fortunately, HP Eliteb

Ethical Hacking - TCP/IP Hijacking

TCP/IP Hijacking is when an authorized user gains access to a genuine network connection of another user. It is done in order to bypass the password authentication which is normally the start of a session. In theory, a TCP/IP connection is established as shown below − To hijack this connection, there are two possibilities − Find the seq which is a number that increases by 1, but there is no chance to predict it. The second possibility is to use the Man-in-the-Middle attack which, in simple words, is a type of network sniffing . For sniffing, we use tools like Wireshark or Ethercap . Example An attacker monitors the data transmission over a network and discovers the IP’s of two devices that participate in a connection. When the hacker discovers the IP of one of the users, he can put down the connection of the other user by DoS attack and then resume communication by spoofing the IP of the disconnected user. Shijack In practice, one of the best TCP/IP hijack too
