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).

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!

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.

2. Hard Drive Interfaces
SATA (Serial Advanced Technology
Attachment) interfaces dominate today’s
market
Integrated Drive Electronics (IDE) / Enhanced
IDE (EIDE) interfaces dominate previous
market
SCSI (Small Computer System Interface)
interfaces is fading away
3. IDE / EIDE
Integrated Drive Electronics and Enhanced
IDE
Hard drive controller is integrated with the drive
Uses the AT Attachment (ATA) interface and a
40-pin ribbon cable
Everyone calls ATA drives IDE
EIDE added some enhancements to IDE
Higher capacities
Support for non-hard drive devices like CD-ROMs
Support for up to 4 hard drives
ATA, IDE, and EIDE are used interchangeably today
to describe all ATA devices
4. IDE/EIDE
EIDE drives connect to the computer via a 40-pin
cable and a controller.
The controller acts as an intermediary between the
hard drive and the external data bus.
When the BIOS talks to the hard drive, it talks to the
circuitry onboard the hard drive
But we still call the connection on the motherboard the
hard drive controller (a misnomer)
Most PCs provide two onboard EIDE controllers to
support up to four hard drives
Use the primary controller if you are only connecting one
device
The other controller is the secondary controller
7. IDE/EIDE
Cabling EIDE Drives:
EIDE drives connect to the controller via a simple 40-pin
cable.
A single cable can connect up to two hard drives: master
and slave based on the jumper settings.
8. 80-wire Ribbon Cables
80-wire ribbon cables still have 40 pins – the
extra wires are used to reduce noise
ATA/66 and
ATA/100 drives
can use the 40-
pin cable but will
operate as an
ATA/33 drive.
9. Jumpers and Labels
Master and
Slave jumpers
Jumper settings
and geometry
shown on the top
of the drive itself
10. CMOS
The CMOS setup should be updated with the drives
geometry after the hard drive is installed in the
system:
With today’s hard drives you may simply set the type to
Auto and the hard drive and CMOS will work it out – up to
four ATA devices may be connected
The CMOS updates itself every time the PC is started
On some older systems you needed to use a menu option
called autodection that searched for new hard drives and
update CMOS
With much older hard drives you must manually enter all of
the geometry – support for only two hard drives maximum
IBM established 15 preset combinations of hard drive
geometries called hard drive types and later added more.
AMI eventually created a new user type that allowed users
to enter the geometry manually
12. Jumper settings for Hard Disk Drives
The hard drive settings can be, but are not limited to,
the following:
MS, MA, DS, 0, or M = Master or Device 0. The
drive is the first drive to be used on the
cable/channel (connected to the end connector on
an IDE cable).
SL, PK, 1, or S = Slave or Device 1. The drive is the
second drive to be used on the cable/channel
(connected to the middle connector on an IDE
cable).
CS, CSEL = Cable Select. The drive can be
automatically set up by a capable system.
16. Jumper settings for 1 hard drive
and 1 CD/DVD drive
Set the hard disk jumper as CS or Single.
Connect the drive using the Master connector
on the primary IDE cable.
Set the CD/DVD drive jumper as CS.
Connect the drive using the Master connector
on the secondary IDE cable.
Note: When using one Western Digital hard drive on
one cable, it may need to be set to "Single". See
hard drive documentation for details.
17. Jumper settings for 2 hard drives
and 1 CD/DVD drive
Set the first hard disk jumper as Master (alternatively, Cable
Select selection can be used but set the 2nd hard drive to Cable
Select). Connect the drive using the Master connector on the
primary IDE cable.
Set the second hard disk jumper to Slave (use the Cable Select
selection if Cable Select was set on the 1st hard drive). Connect
the drive using the Slave connector on the primary IDE cable.
Set the CD/DVD drive jumper as Cable Select. Connect the drive
using the Master connector on the secondary IDE cable.
Note: If Master (MA) is selected on the first device, then the second
device on the same cable must be set to Slave (SL). If Cable
Select (CS) is used on the first device, then the 2nd device on
the same cable must also use CS
18. Jumper settings for 1 hard drive
and 2 CD/DVD drives
Set the hard disk jumper as Cable Select or Single. Connect the
drive using the Master connector on the primary IDE cable.
Set the first CD/DVD drive jumper to Master (alternatively, Cable
Select can be used if you set the 2nd CD/DVD drive selection to
Cable Select). Connect the drive using the Master connector on
the secondary IDE cable.
Set the second CD/DVD drive jumper to Slave (use Cable Select
if Cable Select was used on the 1st CD/DVD drive). Connect the
drive using the Slave connector on the secondary IDE cable.
Note: If Master (MA) is selected on the first device, then the second
device on the same cable must be set to Slave (SL). If Cable
Select (CS) is used on the first device, then the 2nd device on
the same cable must also use CS.
19. Jumper settings for 2 hard drives
and 2 CD/DVD drives
Set the first hard disk jumper to Master (Cable Select can be used if you
set the 2nd hard drive selection to Cable Select). Connect the drive
using the Master connector on the primary IDE cable.
Set the second hard disk jumper to Slave (Use Cable Select if Cable
Select was used on the 1st HDD). Connect the drive using the Slave
connector on the primary IDE cable.
Set the first CD/DVD drive jumper to Master (alternatively, Cable Select
can be used if you set the 2nd CD/DVD drive selection to Cable Select).
Connect the drive using the Master connector on the secondary IDE
cable.
Set the second CD/DVD drive jumper to Slave (use Cable Select if
Cable Select was used on the 1st CD/DVD drive). Connect the drive
using the Slave connector on the secondary IDE cable.
Note: If Master (MA) is selected on the first device, then the second device
on the same cable must be set to Slave (SL). If Cable Select (CS) is
used on the first device, then the 2nd device on the same cable must
also use CS.
20. Fixing Hard Drive Problems
The common causes of hard drive failures are:
Corrupted data on good sectors.
Corrupted data on physically bad sectors.
Installation errors.
Boot sector errors.
Some great tools for a price:
SpinRite by Gibson Research (www.grc.com)
Norton Utilities (www.symantec.com)
Also, the hard drive manufacturer may
have some free downloadable utilities.
21. Corrupted Data on Good
Sectors
Power surges, accidental shut downs,
corrupted install media, and viruses are
common causes of data corruption.
Error messages such as the following occur:
“The following file is missing or corrupt”
“The download location information is damaged”
“Unable to load file”
A disk-checking utility can be used to rectify
such errors.
22. Corrupted Data on Physically Bad
Sectors
The built-in error correction code (ECC) checks the
drive for bad sectors.
Disk checkers can be used for fixing problems
pertaining to corrupted data (such as the one that
comes with Windows – in the Tools tab under the
drive properties)
Windows
2000 disk
checker
23. Installation Errors
Connectivity – Connectivity errors can be
solved by carefully inspecting the connection
system.
CMOS –The autodetection feature can be
used to ensure that the drive geometry is
correct.
Partition – These errors can be solved by
checking the partition in the FDISK, and
making changes to them if required.
24. Boot Sector Errors
These errors show up as boot lockups,
missing drive letters, invalid partition,or bad
or missing command interpreter errors
An antivirus program needs to be run to
ensure that the boot sector is not affected by
any virus.
Restore the boot sector from a backup
If not available, you might try FDISK /MBR
