•Information is a strategic resource.
•A significant portion of the organizational budget is spent on managing information.

 Confidentiality - keep info secret
 Integrity - protect info accuracy
 Availability - ensure info delivery

Ethical Hacking: An Introduction
•Process of legally hacking the information that is considered to be confidential.
•a.k.an Intrusion Testing, Penetration Testing or Red Teaming.

•An expert hired by an organisation to attempt to attack their network and computer system the same way a hacker would.
•Uses the same techniques & tactics used by the hackers.
•End result is the company’s ability to prevent an intrusion, before it occurs.

Types of Hackers
•Script Kiddies :
Amateurs, copy others codes to attack
•White Hat Hackers :
Professional term for ethical hackers
•Black Hat Hackers :
Professional term for malicious hackers
•Gray Hat Hackers :
Combination of both, hack to learn
Self-proclaimed ethical hackers

•Hacktivists :
Hacker + Activists
•State-Sponsored Hackers :
Limitless time & funding by govt.
•Spy Hackers :
Hired hackers by corporations
•Cyber Terrorists:
Motivated by religious / political beliefs
Spread fear, terror, and commit murders

Steps Involved :
•Foot printing/Information Gathering :
Gathering potential information about the target system.
A good hacker consumes 90% of the time for this phase.
•Scanning :
Network is scanned for any vulnerabilities.

•System Hacking :
Involves actual hacking
Taking advantage of vulnerabilities found during scanning, & penetrate the victim’s system.
•Maintaining Access :
Making provisions by planting backdoors
•Covering Tracks :
Removing all the traces of his presence in system by removing log files & event logs

NMAP and ZenMAP

NMAP and ZenMAP are useful tools for the scanning phase of Ethical Hacking in Kali Linux. NMAP and ZenMAP are practically the same tool, however NMAP uses command line while ZenMAP has a GUI. NMAP is a free utility tool for network discovery and security auditing. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. NMAP uses raw IP packets in novel ways to determine which hosts are available on the network, what services (application name and version) those hosts are offering, which operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, etc. Now, let’s go step by step and learn how to use NMAP and ZenMAP. Step 1 − To open, go to Applications → 01-Information Gathering → nmap or zenmap. Step 2 − The next step is to detect the OS type/version of the target host. Based on the help indicat...

Network Topologies •There are three main local area network (LAN) topologies: Bus Star Ring •Other network topologies include: Mesh Wireless What is a server? •Server is a machine which provides services to the nodes or computers in a network and those computers using services are known as client machines. •For each any every service client have to request to the server.

Internet Of Things -IOT

Hey there! Have you heard of IoT? Yes the most popular thing in industry. If not, it is Internet of Things. Do you use smart watches or have you heard about smart city, smart house, these are the practical application of IoT. Didn’t get it?If you just Google “what is IoT?”, you will get a technical answer: “The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.”  Simply, The Internet of Things, or IoT, refers to the billions of physical devices around the world that are now connected to the internet, collecting and sharing data. Now you’ll ask me “Okay, but why is it so much important?”. Today majority of devices works on sensors but sensors will not live forever. In other words, cheap sensors are not going to be 100% reliable, 100% of the time. Ph...
