Enhancement of Action Description Language for UML Activity Diagram ReviewChinnapat Kaewchinporn
The UML activity diagram is graphical presentation that describes the operational process and related causes used in each stage of the system. For understanding and accurate communication, the UML standard is required for determining the congruent and consistent format application. To detect the misconception and incorrect notation, this paper presents an automation approach to reviewing UML activity diagrams based on a domain specific language, called Action Description Language (ADL). The input is the UML activity diagram in the XMI format. Due to the variations of XMI formats, the review process starts with the standardization of the XMI source file. Next, the ADL script will be created using the information extracted from the XMI file. The ADL script will then be verified against the UML constraints defined in the UML standard 2.4.1. The inspection result will be reported. In case of valid activity diagrams, the ADL scripts will be parsed to the ADL semantic model as the final output from the system. The demonstration of the proposed method was performed via three cases. Currently, the implemented prototype can review only the activity diagrams created by ArgoUML and Modelio.

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).

3. Introduction To Software Design
• Deriving a solution which satisfies software requirements.
• Software Design is a process of describing, organizing and
structuring the components of a system.
• Software Design are like set of blueprints in which various
components of the system are shown.
4. Stages of Design
• Problem understanding
• Look at the problem from different angles to discover the
design requirements.
• Identify one or more solutions
• Evaluate possible solutions and choose the most
appropriate depending on the designer's experience and
available resources.
5. Stages of Design (Cont..)
• Describe solution abstractions
• Use graphical, formal or other descriptive notations to
describe the components of the design.
• Repeat process for each identified abstraction
Until the design is expressed in primitive terms.
6. The Design Process
• Any design may be modeled as a directed graph made up of
entities with attributes which participate in relationships.
• The system should be described at several different levels of
abstraction.
• Design takes place in overlapping stages. It is artificial to
separate it into distinct phases but some separation is
usually necessary.

8. PROCEDURAL DESIGN
METHODOLOGY
• A design methodology combines a systematic set of
rules for creating a program design with diagramming
tools needed to represent it.
• Procedural design is best used to model programs that
have an obvious flow of data from input to output.
• It represents the architecture of a program as a set of
interacting processes that pass data from one to another
9. Design Tools
• The two major diagramming tools used in procedural design
are as follows.
1. Data Flow Diagrams
2. Structure Charts (Flow Chart).
10. Data Flow Diagrams
• A data flow diagram (or DFD) is a tool to help you
discover and document the program’s major processes.
The following table shows the symbols used and what each
represents.
11. Sr.
NO
Symbol Used Meaning Example
1
An entity. A source of data or
a destination for data.
2
A process or task that is
performed by the system.
3 A data store, a place where data is
held between processes.
4
A data flow.
12. Relationship and Rules
• The DFD may be used for any level of data abstraction. DFD can
be partitioned into levels. Each level has more information flow
and data functional details than the previous level.
Highest level is Context Diagram. Some important points are:
• 1 bubble (process) represents the entire system.
• Data arrows show input and output.
• Data Stores NOT shown. They are within the system.
13.
14. Level 0 DFD
• Next Level is Level 0 DFD. Some important points are:
• Level 0 DFD must balance with the context diagram it
describes.
• Input going into a process are different from outputs leaving
the process.
• Data stores are first shown at this level.
15.
16. Level 1 DFD
• Next level is Level 1 DFD. Some important points are:
• Level 1 DFD must balance with the Level 0 it describes.
• Input going into a process are different from outputs leaving
the process.
• Continue to show data stores.
17.
18. Difference Between DFD & Flow
Chart
• A DFD may look similar to a flow chart. However, there is a significant difference
with the data flow diagram. The arrows in DFDs show that there is a flow of data
between the two components and not that the component is sending the data
that must be executed in the following component.
• A component in DFD may not continue execution when sending data and during
execution of the component receiving the data. The component sending data can
send multiple sets of data along several connections. In fact, a DFD node can be
a component that never ends. In DFDs, all arrows must be labelled.
25. Is a complete Language for capturing knowledge (semantics)
about a subject and expressing knowledge (syntax) regarding
the subject for the purpose of communication
Applies to Modeling – process of understanding a subject (or
a system)
Is Unified – remaining the same at each stage of development
26. Background
