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).

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.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

• Working with Random Access files
• Standard IO Streams
4. Overview of I/O Streams
To bring in information, a program opens
a stream on an information source (a file,
memory, a socket) and reads the
information sequentially, as shown in the
following figure.
5. Similarly, a program can send
information to an external destination
by opening a stream to a destination
and writing the information out
sequentially, as shown in the following
figure.
Overview of I/O STREAMS
Contd.
6. Overview of I/O streams
Contd..
• The java.io package contains a collection
of stream classes that support algorithms
for reading and writing. To use these
classes, a program needs to import the
java.io package.
• The stream classes are divided into two
class hierarchies, based on the data type
(either characters or bytes) on which they
operate i.e Character Stream and Byte
Stream
7. Character Streams
• Reader and Writer are the abstract
superclasses for character streams in
java.io.
• Reader provides the API and partial
implementation for readers ( streams
that read 16-bit characters ) and
Writer provides the API and partial
implementation for writers ( streams
that write 16-bit characters).
8. Character Streams Contd.
• The following figure shows the class
hierarchies for the Reader and Writer
classes.
9. Byte Streams
• To read and write 8-bit bytes,
programs should use the byte streams,
descendents of InputStream and
OutputStream .
• InputStream and OutputStream
provide the API and partial
implementation for input streams
(streams that read 8-bit bytes) and
output streams (streams that write 8-
bit bytes).
10. Byte Streams (cont.)
• These streams are typically used to
read and write binary data such as
images and sounds.
• Two of the byte stream classes,
ObjectInputStream and
ObjectOutputStream, are used for
object serialization.
13. How to Use File Streams
The file streams-- FileReader , FileWriter ,
FileInputStream , and FileOutputStream -- read or
write from a file on the native file system.
Here is simple code to create a file reader
File inputFile = new File("farrago.txt");
FileReader in = new FileReader(inputFile);
FileWriter out = new FileWriter(outputFile);
This reads characters from the reader as long as
there's more input in the input file and writes
those characters to the writer.
14. How to Use Pipe Streams
• Pipes are used to channel the output
from one thread into the input of
another. PipedReader and PipedWriter
(and their input and output stream
counterparts PipedInputStream and
PipedOutputStream ) implement the
input and output components of a
pipe.
15. How to wrap a stream
Streams are wrapped to combine the various
features of the many streams.
example code:
BufferedReader in = new
BufferedReader(source);
The code opens a BufferedReader on source,
which is another reader of a different type.
This essentially "wraps" source in a
BufferedReader. The program reads from the
BufferedReader, which in turn reads from
source.
16. How to Concatenate Files
• The SequenceInputStream creates a single
input stream from multiple input sources.
example code :
ListOfFiles mylist = new ListOfFiles(args);
SequenceInputStream s = new
SequenceInputStream(mylist);
Here, the mylist object is an enumeration
that SequenceInputStream uses to get a new
InputStream whenever it needs one.
17. Working with Filter Streams
• The java.io package provides a set of abstract
classes that define and partially implement
filter streams. A filter stream filters data as it's
being read from or written to the stream.
• The filter streams are FilterInputStream , and
FilterOutputStream .
• A filter stream is constructed on another
stream (the underlying stream).
18. Object Serialization
• Two stream classes in java.io,
ObjectInputStream and
ObjectOutputStream, are used to read
and write objects.
• The key to writing an object is to
represent its state in a serialized form
sufficient to reconstruct the object as it
is read. This process is called object
serialization.
19. Uses of Object Serialization
• Remote Method Invocation (RMI)--
communication between objects via
sockets
• Lightweight persistence--the archival
of an object for use in a later
invocation of the same program.
20. Working with Random
Access Files
• A random access file permits non-sequential or
random access to a file's contents.
• Using Random Access Files
Unlike the input and output stream classes in
java.io, RandomAccessFile is used for both
reading and writing files. You create a
RandomAccessFile object with different
arguments depending on whether you intend
to read or write.
21. Standard IO Streams
• There are three standard streams, all of which
are managed by the java.lang.System class
• Standard input--referenced by System.in
– Used for program input, typically reads input
entered by the user.
• Standard output--referenced by System.out
– Used for program output, typically displays
information to the user.
• Standard error--referenced by System.err
– Used to display error messages to the user.
