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).

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.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

2. Statistics is the science of conducting
studies to collect, organize, summarize,
analyze, and draw conclusions from
data.
Biostatistics is the application of statistics
to a wide range of topics in biology.
3. • Public health, including epidemiology , health services
research, nutrition and environmental health
• Design and analysis of clinical trials in medicine,
genomics, population genetics and statistical genetics.
• Ecology, ecological forecasting
• Biological sequence analysis
4. Descriptive Statistics consists of collection,
organization, summarization and presentation of
data
Inferential Statistics consists of generalizing
from samples to populations, performing
hypothesis tests, determining relationships
among variables, and making predictions.
5. Data- are the values (measurements or observations)
that the variables can assume. A collection of data
values forms a data set. Each value in a data set is
called datum or data value.
Variable- is a characteristic or attribute that can
assume different values.
eg. Color, height, temperature, texture
Population- consists of all subjects that are being
studied.
sample population-part of the population or a group of
subjects selected from a population
6. Nominal Scale - classifies data into mutually exclusive
(nonoverlapping), exhausting categories in which no order or
ranking can be imposed on the data. No ranking order can
be placed on the data.
eg. Gender- male or female Religion Roman Catholic,
Lutheran, Jewish or Methodist.
Ordinal Scale - classifies data into categories that can be
ranked, however precise differences between the ranks do
not exist.
eg. Pain level- none, mild, moderate, severe
7. Interval Scale- ranks data, and precise difference
between units of measures do exist, however there is
no meaningful zero.
eg : Temperature in °C on 4 successive days
Day: A B C D
Temp °C: 50 55 60 65
Ratio Scale- possesses all the characteristics of
interval measurement, and there exists a true zero.
eg. Weight in pounds of 6 individuals
136, 124, 148, 118, 125, 142
8. Random Sampling Subjects are selected by random
numbers.
Systematic Sampling Subjects are selected by using the
kth number after the first subject is randomly
selected from 1 through k.
Stratified Sampling Subjects are selected by
dividing the population into groups ( strata)
and subjects within groups are randomly selected.
Cluster Sampling Subjects are selected by using
an intact group (clusters) that is representative of the
population.
