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.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

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.

flow and occupy the air spaces.
11. Question 9 – Answer (1)
Concept:
Water boiling
Key words (Question)
Most likely, true
Explanation
A is false – different amount of water means the water will
boil at different times since the amount of heat supplied is
the same.
B is false – both have 2 burners, thus heat energy is the
same.
C is true – boiling temperature is always 100oC no matter
the amount of water.
12. Question 10 – Answer (1)
Concept:
Function of the stomata in plants
Key words (Question)
Layer of cooking oil on both surfaces, died
Explanation
Since the stomata is blocked by the oil, it cannot
take in carbon dioxide (for photosynthesis) and
oxygen (for respiration).
Since oil is transparent, light can still pass

13. Question 11 – Answer (4)
Concept:
Carbon dioxide is taken in during photosynthesis and
given out during respiration.
Key words (Question)

electricity (thus no light produced)
Steel nail is a good conductor of electricity (thus
very bright light produced by bulb)
21. Question 19 – Answer (4)
Concept:
Electrical circuit
Key words (Question)
false
Explanation
A is false – Set up Y is a series circuit
B is false – When batteries are arranged in series, it will
have more electrical energy as compared to a parallel
circuit, thus Y will be brighter.
C is true – When a bulb in series blows, the whole circuit
will fail to work.
D is false – When a bulb in parallel blows, the other bulbs
will continue to light up.
22. Question 20 – Answer (4)
Concept:
Interaction of organisms (how one affect the other)
Key words (Question)
rapidly
Explanation
A will happen – Water hyacinth is a floating plant, if there are too
many, they will cover the surface of the river and block sunlight
from reaching the submerged plants (thus these submerged
plants cannot photosynthesize and produce oxygen.)
B will happen – The water hyacinth will create obstacles for the
boats to travel.
C will happen – Sunlight blocked preventing submerged plants
from making food (same reason as A)
23. Question 21 – Answer (1)
Concept:
Photosynthesis of plants
Key words (Question)
Most adapted, hot and dry
Explanation
P is more adapted to survive in hot and dry
space as it is able to retain the most amount of
water.

Key words (Question)
Changes, D increases
Explanation
less
organisms
eating
more food
more predators
25. Question 23 – Answer (4)

overcrowding
Explanation
Variable to change – size of pot
Variable to keep the same – Number of seeds
and type of soil
26. Question 24 – Answer (3)
Concept:
Forces
Key words (Question)
true
Explanation
A is true – Gravitational force acts from a distance
B is true – Magnets only exert magnetic force on magnetic
objects
C is true – Weight is due to gravitational force acting on it
D is false – (common misconception) An object remains
stationary because frictional force is acting on it, otherwise
it will start moving.
27. Question 25 – Answer (3)
Concept:
Magnets with stronger magnetic force is able to attract pins from a
longer distance
Key words (Question)
Strings of different length, true
Explanation
1. False – Although B attracted the most pins, it is also the nearest to
the pins
2. False – Although C attracted the least number of pins, it is the
furthest away from the pins, thus its magnetic force is not the
weakest
3. True – D and A attracted the same number of pins, but since D is
nearer to the pins, D’s magnetic force is weaker than A’s
4. False – same reason as (3)
28. Question 26 – Answer (2)
Concept:
Extension of the spring is proportional to the mass of
the load
Key words (Question)
Original length, 8 cm, extension, 90g
Explanation
Every 10 g causes the length of spring to increase by 2
cm
Therefore, 90 g 26 cm (length of spring)
Thus extention 26 – 8 = 18
29. Question 27 – Answer (3)
Concept:
Hardness of metals
Key words (Question)
Descending order of hardness
Explanation
A material is hard if it is able to scratch another
material
Y is hardest can scratch W, X and Z
W is 2nd hardest can scratch X and Z
Z is 3rd hardest can scratch X
X is softest cannot scratch any of the 3
30. Question 28 – Answer (2)
Concept:
Light and shadow
Key words (Question)
Smaller shadow
Explanation
The nearer an object to the screen the smaller the
shadow
When you move the light source away from the
object, the shadow becomes smaller as well
31. Question 29 – Answer (3)
Concept:
Heat gain, heat loss – Heat travels from hot to cold
Key words (Question)
Cold milk, hot water, correct
Explanation
A is incorrect – cold milk gains heat from the hot
water
B is correct – the hot water loses heat to the cold
milk, thus the temperature will drop
C is correct – the mug is cooler than the hot water,
thus it gains heat
32. Question 30 – Answer (1)
Concept:
Heat travels
Key words (Question)
Irrelevant
Explanation
1. A is relevant – this experiment shows that heat travels
through matter
2. B is irrelevant – whether matter expends when heated
does not affect the outcome of this experiment
3. C is irrelevant – this experiment is to investigate
whether air, water or metal is a better conductor of
heat
4. D is relevant - this experiment is to investigate
whether air, water or metal is a better conductor of
heat
