A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
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.

3. Introduction
Femtosecond (FS) laser is an infrared
laser with a wavelength of 1053nm. It
works by producing photodisruption
or photoionization of the optically
transparent tissue such as the cornea.
FS laser has pulse duration in the
femtosecond range (10-15 second).
Reducing the pulse duration reduces
the amount of collateral tissue
damage.
4. Properties of Femtosecond lasers
● Passively mode-locked solid-state bulk lasers.
● Emit high-quality ultrashort pulses with typical
durations between 30 fs and 30 ps.
● Various diode-pumped lasers, e.g.
titanium:sapphire or ytterbium-doped crystal
lasers are used.
● Typical average output powers is between 100 mW
and 1 W
● The pulse repetition rate is in most cases between
50 MHz and 500 MHz used to create continuous
cut planes inside the tissue.

8. History of FS Lasers
LensXTM
The first commercial fs
laser designed for
cataract surgery in 2009
IntraLaseTM
The first commercially
available, FDA approved
fs-laser system for
ophthalmology was
launched in 2001 for
LASIK
VisuMax
Recent lasers have a 500-
kHz frequency, so the
flap is cut in about 10
seconds with relatively
low energy.
11. Advantages
Reduced incidence of flap complications like buttonholes, free
caps, irregular cuts etc
Greater surgeon choice as it provides control over flap diameter
and thickness, side cut angle, hinge position and length
Increased precision with improved flap safety and better
thickness predictability
Minimal thermal damage reducing the risk of collateral damage
and promoting faster healing
