3 hydrolastic
Hydrolastic suspension was a type of compact suspension system used in British cars in the 1960s-1970s. It used fluid-filled displacer units attached to each wheel to provide a smooth ride. The key components of the displacer unit included two fluid chambers separated by a flexible diaphragm and piston, which bore the wheel load. Fluid could pass through holes between the chambers to allow movement and dampening of the suspension in response to road conditions. Cars that featured the Hydrolastic suspension system included various Mini, Austin, and Morris models.
5 shock absorbers
A shock absorber uses fluid and valves to damp vibrations from vehicle suspension springs. It consists of an inner cylinder inside an outer reservoir, with a piston connecting the cylinder to the vehicle frame. Fluid passes through the piston and valves as it moves up and down, with resistance from small holes and viscosity of the fluid absorbing energy from vibrations. Telescopic shock absorbers have this basic design but also include a piston rod connecting the inner cylinder to the axle, and valves in the piston and cylinder foot that control fluid flow to provide damping in both compression and rebound strokes.
2 air springs and pneumatic
Air springs come in two types: bellows and piston. Bellows springs consist of rubber bellows that replace coil springs, while piston springs have a metal air container with a sliding piston attached to the lower wishbone.
Air or pneumatic suspension systems are becoming more popular than conventional metal springs for vehicles. They allow for variable wheel deflection control, maintain constant vehicle height to avoid headlight alignment changes, have less variable spring rates between loaded and unloaded states, and provide improved ride comfort and noise reduction to reduce driver fatigue.
An air suspension system works by using an air compressor to fill air springs mounted in the same positions as coil springs to around 240 MPa pressure, stored in an accumulator tank regulated

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 Fuzzing
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.
