Making & Breaking Machine Learning Anomaly Detectors in Real Life by Clarence...CODE BLUE
Machine learning-based (ML) techniques for network intrusion detection have gained notable traction in the web security industry over the past decade. Some Intrusion Detection Systems (IDS) successfully used these techniques to detect and deflect network intrusions before they could cause significant harm to network services. Simply put, IDS systems construct a signature model of how normal traffic looks, using data retrieved from web access logs as input. Then, an online processing system is put in place to maintain a model of how expected network traffic looks like, and/or how malicious traffic looks like. When traffic that is deviant from the expected model exceeds the defined threshold, the IDS flags it as malicious. The theory behind it was that the more data the system sees, the more accurate the model would become. This provides a flexible system for traffic analysis, seemingly perfect for the constantly evolving and growing web traffic patterns.
However, this fairytale did not last for long. It was soon found that the attackers had been avoiding detection by ‘poisoning’ the classifier models used by these PCA systems. The adversaries slowly train the detection model by sending large volumes of seemingly benign web traffic to make the classification model more tolerant to outliers and actual malicious attempts. They succeeded.
In this talk, we will do a live demo of this 'model-poisoning' attack and analyze methods that have been proposed to decrease the susceptibility of ML-based network anomaly detection systems from being manipulated by attackers. Instead of diving into the ML theory behind this, we will emphasize on examples of these systems working in the real world, the attacks that render them impotent, and how it affects developers looking to protect themselves from network intrusion. Most importantly, we will look towards the future of ML-based network intrusion detection.
Outlier and fraud detection using HadoopPranab Ghosh
This document summarizes an expert talk on outlier and fraud detection using big data technologies. It discusses different techniques for detecting outliers in instance and sequence data, including proximity-based, density-based, and information theory approaches. It provides examples of using Hadoop and MapReduce to calculate pairwise distances between credit card transactions at scale and find the k nearest neighbors of each transaction to identify outliers. The talk uses credit card transactions as a sample dataset to demonstrate these techniques.
This document describes an online over-sampling principal component analysis (osPCA) algorithm for detecting outliers in large datasets. Unlike prior PCA approaches, osPCA does not store the entire data matrix or covariance matrix, making it suitable for online or large-scale problems. It works by duplicating potential outlier instances instead of removing them to amplify their effect on the principal components. This allows osPCA to identify outliers by observing variations in the principal directions with and without each data point. The approach can also detect new outliers in an online setting by quickly updating the principal directions for new data.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Anomaly detection via online over sampling principal component analysis
1. Anomaly Detection via Online Over-Sampling Principal Component
Analysis
ABSTRACT:
Anomaly detection has been an important research topic in data mining and machine learning.
Many real-world applications such as intrusion or credit card fraud detection require an
effective and efficient framework to identify deviated data instances. However, most anomaly
detection methods are typically implemented in batch mode, and thus cannot be easily extended
to large-scale problems without sacrificing computation and memory requirements. In this
paper, we propose an online over-sampling principal component analysis (osPCA) algorithm to
address this problem, and we aim at detecting the presence of outliers from a large amount of
data via an online updating technique. Unlike prior PCA based approaches, we do not store the
entire data matrix or covariance matrix, and thus our approach is especially of interest in online
or large-scale problems. By over-sampling the target instance and extracting the principal
direction of the data, the proposed osPCA allows us to determine the anomaly of the target
instance according to the variation of the resulting dominant eigenvector. Since our osPCA need
not perform eigen analysis explicitly, the proposed framework is favored
for online applications which have computation or memory limitations. Compared with the
well-known power method for PCA and other popular anomaly detection algorithms, our

2. experimental results verify the feasibility of our proposed method in terms of both accuracy and
efficiency.
EXISTING SYSTEM:
The existing approaches can be divided into three categories:
1. distribution (statistical),
2. distance and
3. density based methods.
Statistical approaches assume that the data follows some standard or predetermined
distributions, and this type of approach aims to find the outliers which deviate form such
distributions.
For distance-based methods, the distances between each data point of interest and its neighbors
are calculated. If the result is above some predetermined threshold, the target instance will be
considered as an outlier.
One of the representatives of this type of approach is to use a density based local outlier factor
(LOF) to measure the outlierness of each data instance. Based on the local density of each data
instance, the LOF determines the degree of outlierness, which provides suspicious ranking
scores for all samples. The most important property of the LOF is the ability to estimate local
data structure via density estimation. This allows users to identify outliers which are sheltered
under a global data structure
DISADVANTAGES OF EXISTING SYSTEM:
Most distribution models are assumed univariate, and thus the lack of robustness for
multidimensional data is a concern. Moreover, since these methods are typically implemented
3. in the original data space directly, their solution models might suffer from the noise present in
the data
PROPOSED SYSTEM:
PCA is a well known unsupervised dimension reduction method, which determines the
principal directions of the data distribution. This will prohibit the use of our proposed
framework for real-world large-scale applications. Although the well known power method is
able to produce approximated PCA solutions, it requires the storage of the covariance matrix
and cannot be easily extended to applications with streaming data or online settings. Therefore,
we present an online updating technique for our osPCA. This updating technique allows us to
efficiently calculate the approximated dominant eigenvector without performing eigen analysis
or storing the data covariance matrix.
ADVANTAGES OF PROPOSED SYSTEM:
Compared to the power method or other popular anomaly detection algorithms, the
required computational costs and memory requirements are significantly reduced, and
thus our method is especially preferable in online, streaming data, or large scale
problems.

2. Detecting Outliers
3. Clustering
MODULES DESCRIPTION
MODULE - I
Cleaning Data
The osPCA is applied for the data set for finding the principal direction. In this method the
target instance will be duplicated multiple times, and the idea is to amplify the effect of outlier
rather than that of normal data. After that using Leave One Out (LOO) strategy, the angle
difference will be identified. In which if we add or remove one data instance, the direction will
be changed. For normal data instances this angle difference should be smaller and for outliers
this might be larger.
A set of data instances in the original data set is taken as predefined input. This data may be
contaminated by noise and incorrect data labelling etc., This data might be error free, because
this is going to be used as training data. So the cleaning is done using Over-Sampling Principal
Component Analysis (osPCA) method. And then the score of outlierness St is calculated for
each data instances. The smallest St value is taken as the threshold value.
MODULE - II
Detection
6. This is for detecting the outlierness of the user input. When the user giving the input to the
system, the system calculate the St value for the new input. And then compare that new St value
with the threshold value which is calculated in earlier.
If the St value of the new data instance is above the threshold value, then that input data is
identified as an outlier and that value will be discarded by the system. Otherwise it is
considered as a normal data instance, and the PCA value of that particular data instance is
updated accordingly.
MODULE - III
Clustering
The training data will be selected only by our assumption. So there is a possibility that
some outlier data may be considered as normal data in the previous method due to our training
data. So the clustering method is used to solve this problem. The clusters are formed for input
data instances and then the outlier calculation is applied for each cluster to find the outlier
exactly.
