GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
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.

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.
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:

function description
The chip adopts single-line communication mode and uses a return-to-zero code to transmit
signals. After the power-on reset, the chip receives the number from the DIN terminal.According
to the data, after receiving 24 bits, the DOUT port starts to forward data and provides input data
for the next chip. DOUT port before forwarding Keep pulling low. At this point, the chip will not
receive new data, and the three PWM output ports of the chips OUTR, OUTG, and OUTB are
received according to the 24 bit data, the corresponding signal with different duty cycle is issued,
and the signal period is 4 ms. If the input signal to the DIN terminal is the RESET signal, The chip
sends the received data to the display, and the chip will re-receive the new data after the signal is
finished. After receiving the first 24 bits of data,The data is forwarded through the DOUT port.
The original output of the OUTR, OUTG, and OUTB pins remains unchanged before the chip
receives the RESET code.Change, when receiving a low level RESET code above 80μs, the chip
will output the 24-bit PWM data pulse width just received to OUTR,On the OUTG, OUTB pins.
The chip adopts automatic shaping and forwarding technology, so that the number of
cascaded chips is not limited by signal transmission, and only the speed of the screen is limited.
For example, we design a 1024 cascade, which has a screen time of 1024X 0.4X 2 = 0.8192ms
(the data latency of the chip is 0.4 μs), there will be no flickering.

. Attention
.1 Dust & Cleaning
The LED use epoxy glue to package the 5050 Surface, epoxy surface can protect
optical properties and improved anti-aging properties. However, epoxy is a softer material and
prone to attract dust. While a minimal amount of dust and debris on the LED will not cause
significant reduction in illumination.We still need to avoid dust falling on the LED surface. After
open the bags it must be used immediately.
When you use trichloroethylene or acetone to clean, sometimes the LED surface will
dissolve.
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 thepackage 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.
.2 Dehumidification
LED COLOR smart led are moisture sensitive components, In IPC/JEDEC J-STD-020
MSL Level is 6. No Matter the Package bag is open or not ,The LED must do
dehumidification in the oven for 24 hours at 70 degree before use and used within 4 hours,
otherwise it need to be dehumidified again
.3 Reflow Soldering Characteristics
In our Test, LED Color comfirm those smart led are compatible with JEDEC
J-STD-020C,Customers are required to follow the soldering temperature profile recommended by
the solder paste manufacturer used.
Please note that this general guideline may not apply to all PCB design and reflow
soldering equipment configurations.

.4. Anti-static and surge protection for IC devices
Static electricity and surges can damage the LED products of IC devices, so appropriate
protective measures must be taken;
The signal input and output ports of IC devices must be connected in series with protective
resistors to prevent product failure due to surge or electrostatic shock ports;
In order to protect the LED products of IC devices, whenever you encounter LEDs, wear
anti-static straps, anti-static straps and anti-static gloves.
All devices and equipment must be grounded
It is recommended that each product be tested before shipment for relevant electrical tests
to select defective products due to static electricity.
In the design of the circuit, consideration should be given to eliminating the surge to the
LED

Other requirements
SMT nozzle requirements: (red circle refers to the inside diameter of the nozzle)
OK (the inside diameter of the nozzle is larger than NG (the inside diameter of the nozzle is smaller than
the light-emitting area of the lamp) the lighting area of the lamp)
Pressing the colloid surface will affect the reliability of LED because the LED is advanced
silicone-gel.And therefore precautions should be taken to avoid the strong pressure on the
component. It’s proper to make the LED be used in safe condition when using a suction nozzle.
Silicon packing with soft and elastic, it greatly reduces thermal stresses and unable to bear
external mechanical forces. Therefore, preventive measures should be taken in process of
manually handling.
