Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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).

Sdlc process document
1. SDLC, Software Development Life Cycleis a process used by software industry to design, develop and
test high quality softwares. The SDLC aims to produce a high quality software that meets or exceeds customer
expectations, reaches completion within times and cost estimates.
SDLC is the acronym of Software Development Life Cycle.
It is also called as Software development process.
The software development life cycle (SDLC) is a framework defining tasks performed at each step in the
software development process.
ISO/IEC 12207 is an international standard for software life-cycle processes. It aims to be the standard
that defines all the tasks required for developing and maintaining software.
A typical Software Development life cycle consists of the following stages:
Stage 1: Planning and Requirement Analysis
Stage 2: Defining Requirements
Stage 3: Designing the product architecture
Stage 4: Building or Developing the Product
Stage 5: Testing the Product
Stage 6: Deployment in the Market and Maintenance
SDLC Models
There are various software development life cycle models defined and designed which are followed during
software development process. These models are also referred as "Software Development Process Models".
Each process model follows a Series of steps unique to its type, in order to ensure success in process of software
development.
Following are the most important and popular SDLC models followed in the industry:
Waterfall Model
Iterative Model
Spiral Model
V-Model
Big Bang Model
The other related methodologies are Agile Model, RAD Model, Rapid Application Development and Prototyping
Models.
2. SDLC Waterfall Model
Following is a diagrammatic representation of different phases of waterfall model.
The sequential phases in Waterfall model are:
Requirement Gathering and analysis: All possible requirements of the system to be developed are
captured in this phase and documented in a requirement specification doc.
System Design: The requirement specifications from first phase are studied in this phase and system
design is prepared. System Design helps in specifying hardware and system requirements and also helps
in defining overall system architecture.
Implementation: With inputs from system design, the system is first developed in small programs called
units, which are integrated in the next phase. Each unit is developed and tested for its functionality
which is referred to as Unit Testing.
Integration and Testing: All the units developed in the implementation phase are integrated into a
system after testing of each unit. Post integration the entire system is tested for any faults and failures.
Deployment of system: Once the functional and non-functional testing is done, the product is deployed
in the customer environment or released into the market.
Maintenance: There are some issues which come up in the client environment. To fix those issues
patches are released. Also to enhance the product some better versions are released. Maintenance is
done to deliver these changes in the customer environment.
All these phases are cascaded to each other in which progress is seen as flowing steadily downwards (like a
waterfall) through the phases. The next phase is started only after the defined set of goals are achieved for
previous phase and it is signed off, so the name "Waterfall Model". In this model phases do not overlap.
3. SDLC Iterative Model
Following is the pictorial representation of Iterative and Incremental model:
This model is most often used in the following scenarios:
Requirements of the complete system are clearly defined and understood.
Major requirements must be defined; however, some functionalities or requested enhancements may evolve
with time.
There is a time to the market constraint.
A new technology is being used and is being learnt by the development team while working on the project.
Resources with needed skill set are not available and are planned to be used on contract basis for specific
iterations.
There are some high risk features and goals which may change in the future.
4. SDLC Spiral Model
The spiral model has four phases. A software project repeatedly passes through these phases in iterations called
Spirals.
Identification: This phase starts with gathering the business requirements in the baseline spiral. In the
subsequent spirals as the product matures, identification of system requirements, subsystem requirements and
unit requirements are all done in this phase.
This also includes understanding the system requirements by continuous communication between the customer
and the system analyst. At the end of the spiral the product is deployed in the identified market.
Design: Design phase starts with the conceptual design in the baseline spiral and involves architectural design,
logical design of modules, physical product design and final design in the subsequent spirals.
Construct or Build: Construct phase refers to production of the actual software product at every spiral. In the
baseline spiral when the product is just thought of and the design is being developed a POC (Proof of Concept) is
developed in this phase to get customer feedback.
Then in the subsequent spirals with higher clarity on requirements and design details a working model of the
software called build is produced with a version number. These builds are sent to customer for feedback.
Evaluation and Risk Analysis: Risk Analysis includes identifying, estimating, and monitoring technical feasibility
and management risks, such as schedule slippage and cost overrun. After testing the build, at the end of first
iteration, the customer evaluates the software and provides feedback.
Following is a diagrammatic representation of spiral model listing the activities in each phase:
5. V Model
The V - model is SDLC model where execution of processes happens in a sequential manner in V-shape. It is also
known as Verification and Validation model.
V - Model is an extension of the waterfall model and is based on association of a testing phase for each
corresponding development stage. This means that for every single phase in the development cycle there is a
directly associated testing phase. This is a highly disciplined model and next phase starts only after completion
of the previous phase.
The below figure illustrates the different phases in V-Model of SDLC.
6. SDLC Big Bang Model
The Big Bang model is SDLC model where there is no specific process followed. The development just starts with
the required money and efforts as the input, and the output is the software developed which may or may not be
as per customer requirement.
Big Bang Model is SDLC model where there is no formal development followed and very little planning is
required. Even the customer is not sure about what exactly he wants and the requirements are implemented on
the fly without much analysis.Usually this model is followed for small projects where the development teams
are very small.
Agile Model
Here is a graphical illustration of the Agile Model:
Agile thought process had started early in the software development and started becoming popular with time
due to its flexibility and adaptability.Following are the Agile Manifesto principles
Individuals and interactions. In agile development, self-organization and motivation are important, as are
interactions like co-location and pair programming.
Working software. Demo working software is considered the best means of communication with the customer
to understand their requirement, instead of just depending on documentation.
Customer collaboration. As the requirements cannot be gathered completely in the beginning of the project
due to various factors, continuous customer interaction is very important to get proper product requirements.
Responding to change. Agile development is focused on quick responses to change and continuous
development.
7. RAD Model
Following image illustrates the RAD Model:
Following are the typical scenarios where RAD can be used:
RAD should be used only when a system can be modularized to be delivered in incremental manner.
It should be used if there’s high availability of designers for modeling.
It should be used only if the budget permits use of automated code generating tools.
RAD SDLC model should be chosen only if domain experts are available with relevant business knowledge.
Should be used where the requirements change during the course of the project and working prototypes are to
be presented to customer in small iterations of 2-3 months.
Software Prototyping
The Software Prototyping refers to building software application prototypes which display the functionality of
the product under development but may not actually hold the exact logic of the original software.
Software prototyping is becoming very popular as a software development model, as it enables to understand
customer requirements at an early stage of development. It helps get valuable feedback from the customer and
helps software designers and developers understand about what exactly is expected from the product under
development.
8. Following is the stepwise approach to design a software prototype:
Basic Requirement Identification: This step involves understanding the very basics product requirements
especially in terms of user interface. The more intricate details of the internal design and external aspects like
performance and security can be ignored at this stage.
Developing the initial Prototype: The initial Prototype is developed in this stage, where the very basic
requirements are showcased and user interfaces are provided. These features may not exactly work in the same
manner internally in the actual software developed and the workarounds are used to give the same look and
feel to the customer in the prototype developed.
Review of the Prototype: The prototype developed is then presented to the customer and the other important
stakeholders in the project. The feedback is collected in an organized manner and used for further
enhancements in the product under development.
Revise and enhance the Prototype: The feedback and the review comments are discussed during this stage and
some negotiations happen with the customer based on factors like, time and budget constraints and technical
feasibility of actual implementation. The changes accepted are again incorporated in the new Prototype
developed and the cycle repeats until customer expectations are met.
Summary
This was about the various SDLC models available and the scenarios in which these SDLC models are used. The
information in this tutorial will help the project managers decide what SDLC model would be suitable for their
project and it would also help the developers and testers understand basics of the development model being
used for their project.
We have discussed all the popular SDLC models in the industry, both traditional and Modern. This tutorial also
gives you an insight into the pros and cons and the practical applications of the SDLC models discussed.
Waterfall and V model are traditional SDLC models and are of sequential type. Sequential means that the next
phase can start only after the completion of first phase. Such models are suitable for projects with very clear
product requirements and where the requirements will not change dynamically during the course of project
completion.
Iterative and Spiral models are more accommodative in terms of change and are suitable for projects where the
requirements are not so well defined, or the market requirements change quite frequently.
Big Bang model is a random approach to Software development and is suitable for small or academic projects.
Agile is the most popular model used in the industry. Agile introduces the concept of fast delivery to customers
using prototype approach. Agile divides the project into small iterations with specific deliverable features.
Customer interaction is the backbone of Agile methodology, and open communication with minimum
documentation are the typical features of Agile development environment.
RAD (Rapid Application Development) and Software Prototype are modern techniques to understand the
requirements in a better way early in the project cycle. These techniques work on the concept of providing a
working model to the customer and stockholders to give the look and feel and collect the feedback. This
feedback is used in an organized manner to improve the product.
