Machine Learning: Light GBM and Support Vector Machine, Neural Network like CNN, RNN

Technology: Python, Apache Spark, Pytorch, Apache Kafka, Flume, MongoDB, Jenkins, Git

Supported Platforms: Ubantu 17.0, Cent OS

Team Size: 12

Duration: Dec 2017 to June 2019

Overview:

Manage Detection and Response is a combination of technology and skills to deliver advanced threat detection, deep threat analytics, global threat intelligence, faster incident mitigation, and collaborative breach response on a 24x7 basis.

The endpoints (IOT devices and Enterprise servers) have system scanning done by EMS system or scan component. Apache Flume agents capture the logs and sends to Topic in Apache Kafka.

The queue is consumed using Apache Spark Steam component. The data is reduced and stored in Cassandra for Machine Learning.

The data is processed using Machine Learning for threat detection. The output is stored in Mongo DB and displayed in dashboard.

Machine Learning Algorithm techniques like Ensemble Learning & Boosting like Support Vector Machine, Light GBM, CNN, RNN are applied to best possible result is derived.

Overview:

Endpoint Detection and Protection Response detects, protects and responds to cyberattacks which adds to the complexity of securing the enterprise. Each of the point products adds an agent to the endpoint and is often managed independent of the other security technologies present on that endpoint.

Machine Learning: This involves Feature Extraction and Feature Engineering for malware based on Static Analysis for PE and PDF file types.

The metadata is extracted from malware samples. Thereafter, Data Pre-Processing, Data Cleaning is done.

Based on exploratory analysis, regularly model is created/updated and validated.

Overview:

IGA is integrated access management and governance product which takes care entire life cycle of employee engagement (on boarding and exit). During On boarding, employee id is created, access to different system is given after approval. During exit, all the access and id are revoked.

Machine Learning

The data collected from multiple system like attendance system, leave portal, access management, training system, appraisal system and other client multiple system.

The collected data cleansed, parsed, validated and thereafter feature selection and engineering, exploratory data analysis are applied to derive multiple metrics. Powerful dashboard is created using Tableau.

<!--[if !supportLists]-->·      <!--[endif]-->The project is to detect the red blood cells in blood sample. The training of data was done from the below dataset: Https://github.com/cosmicad/dataset

<!--[if !supportLists]-->·      <!--[endif]-->The dataset contains blood images and annotated files for training

<!--[if !supportLists]-->·      <!--[endif]-->YOLO algorithm was used for training the dataset. YOLO is an extremely fast real time multi object detection algorithm. YOLO actually looks at the image just once by dividing the image into a grid of 13 by 13 cells. Each of these cells is responsible for predicting 5 bounding boxes which describes the rectangle that encloses an object. YOLO also outputs a confidence score that tells us how certain it is that the predicted bounding box actually encloses some object. This score doesn't say anything about what kind of object is in the box, just if the shape of the box is any good. For each bounding box, the cell also predicts a class. This works just like a classifier: it gives a probability distribution over all the possible classes. YOLO was trained on the PASCAL VOC dataset. The confidence score for the bounding box and the class prediction are combined into one final score that tells us the probability that this bounding box contains a specific type of object. Since there are 13×13 = 169 grid cells and each cell predicts 5 bounding boxes, we end up with 845 bounding boxes in total. It turns out that most of these boxes will have very low confidence scores, so we only keep the boxes whose final score is 30% or more (you can change this threshold depending on how accurate you want the detector to be)
