What is Confusion Matrix

In the field of machine learning and specifically the problem of statistical classification, a confusion matrix, also known as an error matrix, is a specific table layout that allows visualization of the performance of an algorithm, typically a supervised learning one.

What is TP / TN / FP / FN ?

True Positive (TP) :
The predicted value matches the actual value
The actual value was positive and the model predicted a positive value

True Negative (TN) :
The predicted value matches the actual value
The actual value was negative and the model predicted a negative value

False Positive (FP) – Type 1 error:
The predicted value was falsely predicted
The actual value was negative but the model predicted a positive value
Also known as the Type 1 error

False Negative (FN) – Type 2 error:
The predicted value was falsely predicted
The actual value was positive but the model predicted a negative value
Also known as the Type 2 error

Now let us Discuss what is Cyber Crime ?

Cybercrime, or computer crime, is a crime that involves a computer and a network. The computer may have been used in the commission of a crime, or it may be the target. Cybercrime may harm someone's security and financial health.

How Confusion Matrix has an Important take in Cyber Crimes ?

False Postivies :
False positives are mislabeled security alerts, indicating there is a threat when in actuality, there isn’t. These false/non-malicious alerts (SIEM events) increase noise for already over-worked security teams and can include software bugs, poorly written software, or unrecognized network traffic.

False Negativies :
False negatives are uncaught cyber threats — overlooked by security tooling because they’re dormant, highly sophisticated (i.e. file-less or capable of lateral movement) or the security infrastructure in place lacks the technological ability to detect these attacks.

Running GUI Applications inside Docker Container

What is DOCKER?

Docker is a set of platform as a service products that use OS-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.

What is GUI ?

The graphical user interface is a form of user interface that allows users to interact with electronic devices through graphical icons and audio indicator such as primary notation, instead of text-based user interfaces, typed command labels or text navigation.

Lets Directly Jump to Practicles :

Docker Engine Must be Installed in the Base OS / Host .

To confirm whether docker is installed or not we can use :
[root@os]~# docker --version

Docker Engine must be in running state .
[root@os]~# systemctl start docker

[root@os]~# systemctl status docker

We must have a docker image to execute our task .

[root@os]~# docker pull centos:latest

We will now create a Dockerfile in which we will specify our Requirements for our own custom Image

[root@os]~# vim Dockerfile

FROM centos:latest
RUN yum install firefox -y

[root@os]~# docker build -t firefox:v1 .

docker build will help us to make our own customized image with tag firefox:v1

[root@os]~# docker run -it --name task2 -e DISPLAY=$DISPLAY --net=host firefox:v1

$DISPLAY == Enivornment Variable for our Display :0 is the main display.
--net=host == Using Socket to make connect between docker and base OS (Host)

[root@os]~# firefox

[root@os]~# jupyter notebook

In Addition to firefox i used jupyter notebook as a GUI APP.

What is Machine Learning?
Machine learning is the study of computer algorithms that improve automatically through experience and by the use of data. It is seen as a part of artificial intelligence.
