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).

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.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
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.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
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.
Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Test requirements:
1. RV rubber recycling chemical
2. Open mill
3. Rubber scraps or rubber powder
Technique process& Advantages:
Put 100PHR rubber waste or rubber powder and 3PHR RV rubber recycling chemical on open mill, milling for
10-15 mins under normal temperature and pressure. Then we get the revived rubber compounds(RVR),RVR can be
cured without any sulphur and accelerator, and RVR can be used singly or replace the raw rubber compounds for
20-70% .
The technique can be used for scorched rubber also, and the formula is 0.5-2:100(RV: scorched rubber)
Property comparison for RVR and normal reclaimed rubber(Applicated for tire
tread):
A#- -RVR-Processed by RV Rubber recycling chemical and 40meshes rubber powder
B#-- Rubber powder, activation rubber powder and fine reclaimed rubber
The conclusion under same mixing proportion:
1. A# gains better Vulcanizing performance than B#;
2. The re-treated tire mixed with A# has similar wear-resisting property with the original re-treated tire
formula

rubber powder gains better vulcanization property. But the vulcanization retention is same, so it shows that RV
rubber recycling chemical has same restore property to the two kinds of rubber powder. RVR can be used to replace
the raw rubber tread compounds, so the cost of sulphur and accelerator was saved.
2.2 Different influences of RVR to the tire tread properties

Sheet 2 shows, mixed tire tread materials made from different kinds of rubber powder, property retention of the
hardness, stress at definite elongation, elongation at break and tensile strength is same, the tear strength is different,
it is because of the dust inside rubber powder. The test shows, different kinds of rubber powder makes different
kinds of vulcanizing property, but when mixed the off-the-road tire rubber powder and truck tire powder, the
vulcanization property is nearly the same.
2.3 Reclaimed rubber and mixed percentage influence for the tire tread property

2.5 Economic benefit analysis
Compare from the mixing dosage of RVR, 40 meshes activation rubber powder and fine reclaimed rubber, we
can see from Sheet 3 that, if we need the tire tread tensile strength to be 25Mpa, so we can only mix 10% of 40
meshes activation rubber powder, 15% of fine reclaimed rubber, but RVR 40%. If we take the cost of origin tire
tread rubber for 15500RMB/T, RVR 7000RMB/T, 40meshes activation rubber powder 5000RMB/T, fine reclaimed
rubber 3800RMB/T, RVR mixed tire tread material cost is 2350RMB/T less than 40 meshes activation rubber
powder, and 1645RMB/T than fine reclaimed rubber.

If we take it retreated tire 2500pcs per year, and cost tire tread materials 30T, and the origin tire tread cost
15500RMB/T, so we can save cost 76500RMB/year(without the cost which saved from sulphur and accelerator). So
it shows, RVR is with better economic benefit.
3 Conclusion
1) RV rubber recycling chemical have different kinds of effect on different kinds rubber powder, and the
RVR can be vulcanized directly.
2) Vulcanization property of better quality RVR and worse RVR is nearly same.
3) Vulcanization property of the tire tread mixed with RVR is better than other kinds of rubber powder,
under same mixing dosage.
4) Mileage test shows, it is reasonable to mix 15-40% of RVR into retreated tire tread, the retreated tire
property is fit for the national standard.
5) Using RVR in retreated tire can save much of the cost.
6) Anti-origin resistance can be improved by mixing of RVR.
