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.

acetone were applied.
Avoid using organic solvent, it is recommended that isopropyl be used as a solvent for cleaning the
LEDs. When using other solvents, it should be confirmed beforehand whether the solvents will
dissolve the package and the resin of not.
Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence as ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power. Baking time and assembled
condition. Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs
will occur.
3.2. Moisture Proof Package
In order to avoid the absorption of moisture during transportation and storage, LED are packed
in the aluminum envelop, A desiccant is included in the aluminum envelop as it absorbs
moisture. When moisture is absorbed into the AMT package it may vaporize and expand
during soldering. There is a possibility that this can cause exfoliation of the contacts and
damage to the optical characteristics of the LEDs. For this reason, the moisture proof
package is used to keep moisture to a minimum in the package.
3.3. Storage
In order to avoid the absorption of moisture, It is recommended to store SMD LED (in bulk or taped) in the
dry box (or the desiccator ) with a desiccant, Otherwise to store them in the following environment as
recommended.
a. Temperature: 5℃~30℃ b. Humidity: 60% RH Max
It is recommended to solder the LED as soon as possible after unpacking the aluminum envelop, But in
case that the LED have to be left unused after unpacking envelop again is requested.
The LED should be soldering within 1 hours after opening the package.
If baking is required, A baking treatment should be performed as
follows:
70℃±5℃ for more than 24 hours.

3.5 Heat Generation:
Thermal design of the end product is of paramount importance. Please consider the heat
generation of the LED when making the system design. The coefficient of temperature increase
per input electric power is affected by the thermal resistance of the circuit board and density of
LED placement on the board, as well as components. It is necessary to avoid in tense heat
generation and operate within the maximum rating given in this specification. The operating
current should be decided after considering the ambient maximum temperature of LEDs
3.6 Electrostatic Discharge & Surge Current :
Electrostatic discharge (ESD) or surge current (EOS) may damage LED.
Precautions such as ESD wrist strap, ESD shoe strap or antistatic gloves must be worn
whenever handling of LED.
All devices, equipment and machinery must be properly grounded.
It is recommended to perform electrical test to screen out ESD failures at final inspection. It is
important to eliminate the possibility of surge current during circuitry design.
3.7 Moisture Proof Package
Cannot take any responsibility for any trouble that are caused by using the LEDs at conditions
exceeding our specifications.
The LED light output is strong enough to injure human eyes. Precautions must be taken to
prevent looking directly at the LEDs with unaided eyes for more than a few seconds.
The formal specification must be exchanged and signed by both parties before large volume
purchase begins. The appearance and specifications of the product may be modified for
improvement without notice.
