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).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

2. A Wide Area Network (WAN) is a telecommunication network that
spans a large geographic area. It usually connects two or more Local
Area Networks (LAN) by means of dedicated lines or packet/circuit
switching.
3. Characteristics of a WAN
The best example of a Wide Area Network is The
Internet!
S A WAN consists of a large numbers of nodes/hosts that
are interconnected by a subnet
S To be considered a WAN, the network must span 30+
miles
4. WAN Applications
S Wide Area Networks can be used in most any application
of transmitting voice, video, or data across long distances
S Voice: most phone service providers merge hundreds &
thousands of analog phone calls onto a single digital
medium for transmission across town or across the country
S Video: dedicated WAN systems, such as ATM (explained
later) allow for high-quality video stream with low latency
S Data: the creation of a direct connection between two nodes
on a private WAN is much more efficient & secure that
sending data across with general Internet traffic
6. WAN Technologies
S A WAN can use multiple types of telecommunication mediums…
S Copper Wire
S Fiber Optic Cabling
S Radio Links
S Satellite Links
S The Data Link Layer (OSI layer 2) uses various protocols along these
mediums to describe how frames are encapsulated & transmitted.
Some common ones are…
S Public Switched Telephone Network (PSTN)
S Integrated Service Digital Network (ISDN)
S Frame Relay
S Asynchronous Transfer Mode (ATM)
7. Leased Lines
S Dedicated connections that are usually leased through a
network carrier
S Available in various capacities depending upon distance
between sites & bandwidth required.
S While very reliable, cost is considerably more than other WAN
options that utilize shared (switch) connections
8. Circuit Switching Networks
S These networks establish a dedicated circuit (or channel)
between nodes for users to communicate
S This means that every switch along the network is set in
such a fashion that the data flows continuously from node
to node
9. Public Switched Telephone Network
S A Point-to-Point Protocol (PPP) network that may consist of more than
one leg between two hosts, however the source & destination are
connected by a direct connection
S Very popular option for using a dial-up telephone modems. This is an
example of a circuit-switched network
S Authentication is supported with Password Authentication Protocol
(PAP) & Challenge Handshake Authentication Protocol (CHAP)
10. Integrated Service Digital
Network
S International communication standard for sending voice,
video & data via telephone wires
S Works much like PSTN, but offers higher speeds closer
to DSL rather than 56Kbps analog dial-up service
11. Packet Switching Networks
S In contrast to circuit switching, packet switching splits
traffic into packets that are individually routed over a
shared network
S DO NOT require a dedicated circuit to be established;
allows many pairs of nodes to communicate over the
same channel
S Each switch in the network routes a packet based upon
the addressing information in the header frame
12. Packet Switching Networks
(cont.)
S Connectionless Systems carry full addressing information
requiring each switch to completely evaluate routing
S Connection-Oriented Systems predetermine the route for
each packet.
S Packets are only required to carry an identifier in the header
S Each switch has a table of predetermined routes that correspond
to different identifies stored in memory. The identifier on the
packet is checked with this listing & then assigned a route by the
router
13. Frame Relay
S Creates a private network connection through a carrier's network
S T1 Line (or other leased line) from network carrier along with a frame-
relay port. The network can be designed to include as many nodes as
needed, each connected via a Permanent Virtual Circuit (PVC). This is
an example of packet-switched network
S This option is fairly cheap because each connecting node only needs
a PVC & leased line to be connected with the WAN
S This technology is slowly
being replaced by faster services
14. Asynchronous Transfer
Mode
S ATM is a dedicated connection-oriented switching system that
organizes all data into 53-byte cells before digitally sending
them
S Each cell is processed asynchronously relative to other cells &
is queued before being multiplexed over the transmission path
S Low latency coupled with speeds up to 10Gbps, makes the
technology ideal with high intensity video data applications
16. Public WAN’s
The Internet
S In contrary to private WAN’s, public WAN’s have no isolation between
users/customers
S Cheaper, greater bandwidth (usually gigabit or higher)
S DSL, Cable Modem, Fiber Optic, etc.
S Companies can create virtual WAN’s by use of technologies such as
VPN that “tunnel” & encrypt traffic over the general-public Internet
17. Public WAN’s Threat
to Private WAN’s
S Virtual Private Networks (VPN) allows the creation a of
virtual point-to-point connection means of dedicated
connections, tunneling protocols, or traffic encryption.
These networks are much cheaper than WAN’s & allow
more flexibility as they only need an Internet connection
to operate.
S Cloud computing is more cheaper & simple to utilize in
most applications today.
In 2014, one survey of IT professionals indicated that nearly 50%
of those currently using WAN technologies were in the process of
implementing new Cloud technologies to replace them.

Editor's Notes
LAN vs. CAN vs. MAN vs. WAN
Circuit networks allow only one path, whereas Packet networks allow more than one path
Taking bus to school (public) vs. driving car to school (private)
Traditional private WAN networks are beginning to downsize as more cost-efficient options become available, such as VPN or Cloud computing. Many end users can now utilize the public WAN (The Internet) along with these technologies to conduct secure activities that once required private WAN’s.
