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).

1.
2. The term "scripting" is also used loosely or weakly typed or light weight programming
to refer to dynamic high-level general-purpose languages. Scripting languages are
becoming more popular due to the emergence of web-based applications.
Script languages are two main types:
1. Executing commands in batch mode
Example: .bat (MSDOS) .sh(Shell-UNIX)
2. Designed for text processing and report generation
Example: sed, awk(Aho, Weinberger, and Kernighan)
Client-side scripting languages affecting the data that the end user sees in a
browser window. Server-side scripting languages are manipulate the data,
usually in a database, on the server. Scripts are Glue code, also called binding
code, is custom-written programming that connects incompatible software
components.
3. Scripting Languages are Classified into the following two types:
1. Client Side Scripting Languages
2. Server Side Scripting Languages
CLIENT SIDE SCRIPTING LANGUAGES
The script which is running within the browser is called as client side scripting.
Live Script
JavaScript
jQuery etc.
Type Script
Action Script
VBScript
HTML (Structure)
CSS (Designing)
AJAX
4. Server Side Scripts
The Script which is running within the web server is called as
server side scripting.
Python ==>SimpleHTTPServer
ASP ==>IIS (Internet Information Services)
JSP ==>Tomcat/Sun Java System Web Server
PHP ==>Apache
CGI ==> Common Gateway Interface
Server-side JavaScript (SSJS) Example. node.js
PERL Practical Extraction and Reporting Language
R Programming Language
5. Characteristics of Interpreted Languages
1 Interpreted languages is that they require no compilation.
2 Makes them easy to learn and use
3 Assumes minimum programming knowledge or experience
4 Allows complex tasks to be performed in relatively few steps
Characteristics of Compiled Languages
1 Programming language whose implementations are typically compilers
2 Intermediate code generation
3 Code optimisation
4 Machine code generation
6. Scripting Languages:
1. Interpreted based (Read Line by Line)
2. Implicit Declaration of data types
3. Limited Support for Application Development
4. Limited Support for Graphics Design or Game(s) Development
5. Easily Integrated with other Technologies
Programming Languages:
1. Compiler based
2. Explicit Declaration of data types
3. Rich Support for Application Development
4. Rich Support for Graphics Design or Game(s) Development
5. Difficult to Inegrate with Other Technologies
7.
8. IMPERATIVE PARADIGM
That uses statements that change a program's state. It consists of commands for the
computer to perform. Paradigm means Model or Pattern
Procedural Programming Paradigm
It is based on the concept of using procedures. Procedure (sometimes also called
subprogram, routine or method) is a sequence of commands to be executed.
Example: C, Pascal
Object-oriented Programming Paradigm
It is a programming paradigm based on the concept of "objects", which may contain
data, in the form of fields, often known as attributes.
Example: C++, Simula (Simulation Programming Language), JAVA
Mutable:
A mutable object is any object which can be modified after it’s created.
Immutable:
An immutable object is an object that can’t be modified after it’s created.
9. A style of building the structure and elements of computer programs,
that expresses the logic of a computation without describing its control
flow.
Functional Programming Paradigm
It is the process of building software by composing pure functions,
avoiding shared state, mutable data, and side-effects.
Example: LISP (List Processing)
Logical Programming Paradigm:
Logic programming is a type of programming paradigm which is largely
based on formal logic.
Example: PROLOG (Programming in Logic)
10. Python is an easy to learn, powerful programming language. The application
development process much faster and easier. Python is available under the
license GNU General Public License (GPL) or Free Software Foundation
(FSF).
OR
Python is a multi-paradigm Programming language invented by Guido Van
Rossum.
Multi-paradigm==> "paradigm" refers to object-oriented, procedural,
functional, logical, etc.
11.
12. 1. Invented in the Netherlands in early 1990s by Guido Van Rossum at
CWI (Centrum Wiskunde & Informatica) now at Google.
2. Python was named for the BBC TV show "Monty Python's Flying
Circus".
3. Open source and interpreted language.
4. Considered a scripting language, but is much more than that
5. Scalable, object oriented and functional.
6. Used by Google and Microsoft, increasingly popular.
7. Python job trends from indeed.com shows remarkable increase
8. Python is at the top of the list among the top-Java, JavaScript and
PHP
13. Software Quality
Python focuses on readability, coherence, and software quality in general which sets it
apart from other languages in the scripting world.
Developer Productivity
Python code is typically one-third to one-fifth the size of equivalent C++ or Java code.
That means there is less to type, less to debug, and less to maintain.
Program Portability
Python programs run unchanged on all major computer platforms. For Example:
Windows, Linux, MAC OS etc.
Support Libraries
Python comes with a large collection of prebuilt and portable functionality, known as
the Standard Library
Component Integration
Python scripts can easily communicate with other parts of an application, using a
variety of integration mechanisms.
Enjoyment
Because of Python’s ease of use and built-in toolset, it makes the programming more pleasurable.

31. Python’s traditional runtime execution model: source code you type is translated to
byte code, which is then run by the Python Virtual Machine. Your code is
automatically compiled, but then it is interpreted.
Source code extension is .py
Byte code extension is .pyc (compiled python code)
