What is Cyber Security?

Cyber Security includes sensitive data , personally identifiable information, protected health information, personal information , intellectual property , data , and governmental and industry information systems. Without a good cybersecurity experts , your organization is expose itself against data breach and irresistible target for cybercriminals. Both inherent risk and residual risk is increasing due to global connectivity and usage of cloud service like Amazon Web Services to store sensitive data and personal information.

Poor configuration of cloud service will allow sophisticated cybercriminals to create risk to your organization to suffer from a
successful cyber attack or data breach. Business leader can no longer solely rely on out-of-the-box cybersecurity solution like antivirus software and firewall, cybercriminals are getting smarter and their tactic are becoming more resilient to conventional cyber defenses.
Cyber threat can come from any part of your organization . You must provide awareness to your staff about simple social engineering scam like phishing and more sophisticated cybersecurity attack like ransomware attack or even other malware designed to steal intellectual property or personal

What is Python Turtle Coding For Kids?

Learning to code offer kids a way to develop and train a range of different skill perceived a useful in other school subject , like creativity ,
problem solving and persistence. Even though learning how to code can be difficult there are some approach that can reduce those difficulty .
We need take the age of the kid into consideration (At-least 10 years old) , but learning coding should be fun. A turtle-shaped cursor draw a 10-point star and it moves around the window frame is known as turtle graphic that are vector graphic and image produced by a small turtle-shaped cursor moving around the screen. It shows that a kid around 8-10 year old should be able to understand the exercise to be coded. The disadvantage of learning python turtle is that it has little to no practical usage in the real world or even the school subjects. Fortunately , Python has a turtle module can be used to learn coding the same way you would with C++ , although using a different syntax. Python is the most widely used programming language worldwide and the one that has been popular in recent year .

Below is a simple code for Python Turtle

import turtle

painter = turtle.Turtle()


for i in range(50):
painter.left(123) # Let’s go counterclockwise this time

for i in range(50):

Why Python Programming Is So Important

Choosing the right programming tool will decide your entire success in your software project.Choosing the wrong programming tool, you’ll end up losing more money and even the client too. Your work productivity will be slower and your competition may out beat you and finally your project results may end up below expectations. When you choose the right programming tool, gives a lot of advantages in completing the software projects. If what you’re building is a software project for your company, your core programming tool is your programming language. For your software project to be a success, we recommend that you choose Python for your programming tool.

Python has a healthy community that makes every day to make the language better with improve libraries. Writing Python code is very easy , which can speed up development and making it highly productive. A programmer friendly environment for your building programming tool and more time spent actually focusing on the project. Python gives a pool of many frameworks and libraries .

On the other hand, it’s true that Python’s runtime is slower compared to other languages, Python is still heavily used by companies such a Google. Because CPU time is rarely the limiting factor. The one limited resources is the employee’s time.Employee’s like software developers are not cheap. On top of it, Python also uses fewer lines of code to achieve results comparing with language such a C or Java or even Microsoft DotNet.The simplicity of Python has help many developers to read the code you’ve written or written code by other developers.

Tracking Packets Over Your Network

NeoTrace is from NeoWorx Inc. and it provides you a simple way whether your packets reach the destination or not.It captures all the information about the hops and IPs and relays it back to you eventually.

When you move your mouse over a node, it shows the name of the computer, the IP address, the longitude and latitude, the physical address, and the total number of the nodes in between your computer and the destination. The Nodes tab show what goes on when it is tracing an ip address.

NeoTrace can do more than ping routers and computers and it allows to shows their locations around the world as your data travels across the Internet.

If a router is not configured to relay any information, it will label it as gray.The List will arrange all the nodes in order with the IP addresses and the names of the computers and the type of networks they correspond too.

Best useful feature is that the tab tells the length of the trace. The Graph tab shows the differences in connectivity and speed. Very useful for administrators who want to discover slow sections in a network. NeoTrace in reality it works by sending small packets of incomplete data to all the computers in the network.

Creating A Simple IP Packet Using Collasoft Packet Builder

Colasoft Packet Builder is one of the best tools to create and craft ip packets for simulation and testing. You can also edit ip packet raw data with HEX editor. Besides common HEX editing raw data, it features a Decoding Editor allowing users to edit specific protocol field values much easier. You can easily select any of the packets starting from Ethernet Packet, ARP Packet, IP Packet, TCP Packet and UDP Packet, and modify the parameters in the decoder editor, hexadecimal editor or ASCII editor to create or initialize the packets.

While it is able to build packets, you can also save packets to packet files and send the packets to the local network.This program provides several way to create packets:
You can also easily import a existing packet trace file created by sniffers like Colasoft Capsa, Wireshark, Network General Sniffer and WildPackets EtherPeek/OmniPeek etc.
You can Add Packet command in Edit menu or Toolbar to create a new packet, the Builder provides several common-used packet format- Ethernet Packet, ARP Packet, IP Packet, TCP Packet and UDP Packet.

Personally I have simulated and tested Denial of Service in the local network using Colasoft Packet Builder. You will notice your computer will start to get slower and this can be seen in the cpu usage area.

If you have installed Colasoft Capsa, then you find it easier to send packets in Capsa to Packet Builder on the fly.
