Operational technology (OT) and information technology (IT) security protect devices, networks, systems, and users. Cybersecurity has long been critical in IT and helps organizations keep sensitive data safe, ensure users connect to the internet securely, and detect and prevent potential cyberattacks.
IPS (Intrusion Prevention System) is definitely the next level of security technology with its capability to
provide security at all system levels from the operating system kernel to network data packets. It
provides policies and rules for network traffic along with an IDS for alerting system or network
administrators to suspicious traffic, but allows the administrator to provide the action upon being
alerted. Where IDS informs of a potential attack, an IPS makes attempts to stop it. Another huge leap
over IDS, is that IPS has the capability of being able to prevent known intrusion signatures, but also
some unknown attacks due to its database of generic attack behaviours. Thought of as a combination of
IDS and an application layer firewall for protection, IPS is generally considered to be the "next
generation" of IDS.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

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.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

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

The What and How!
34. 34
Start: A plant network in need of organizing
▪ Mix of units with different
purposes and criticality
▪ Single, flat network (switched)
▪ Or multiple networks, each with
mix of units
▪ Little or no control of traffic
patterns within the Intranet

Goal: A network with proper segmentation
▪ Group units based their purpose
▪ Segment network accordingly
(zones)
▪ Connect via router/firewall capable
of segregating traffic flows
▪ May use multiple firewalls
▪ Possibly from different vendors
▪ Can have external FW managed by
IT department (IT FW)
▪ The internal FW can be dedicated to
operations (OT FW)

Segmentation: Local Area Networks
▪ What is a LAN?
▪ LAN – Local Area Network
▪ Sometimes it means ”your local
network”, i.e., your whole Intranet
▪ Here we use LAN when referring to a
broadcast network, typically using IEEE
802.3/Ethernet technology.
▪ Form star topology by using a
switch/hub/bridge to connect Ethernet
equipment.
▪ Switches can be connected together to
extend the LAN (tree topology).
▪ Connecting switches in a ring improves
robustness (requires RSTP, FRNT, ...)
Connecting units to LAN via a switch (Star Topology)
Using multiple switches to extend the LAN (Tree Topology)
38. 38
Segmentation: Virtual Local Area Networks
▪ What is a VLAN?
▪ VLAN - Virtual LAN
▪ Your LAN equipment is split into logical,
isolated LANs (isolated broadcast
domains)
▪ Sharing a single switch
▪ Port based VLAN
▪ Split a single switch
▪ Extend VLAN over multiple switches
▪ VLAN trunk cables
▪ ”VLAN tag” added
▪ Holds multiplex info (VLAN ID)
VLAN 10 VLAN 20
VLAN 10 VLAN 20 VLAN 10 VLAN 20
VLAN trunk: VLAN 10 & 20
VLANs to share switch (Port based VLAN)
VLANs spanning multiple switches (Port based VLAN and VLAN tagging)
39. 39
Using VLANs to segment our network
▪ Configure VLANs on the (OT)
Firewall/Router
▪ Creates one zone for each network
▪ Within each zone there are
additional switches (not shown)

Assigning IP addresses/subnets
▪ IP addresses: Identifies a unit and its
location
▪ Logically assigned
▪ Network part and Host part
▪ Assign one subnet per VLAN, e.g.,
▪ 10.0.10.0/24: Office Net
▪ 10.0.20.0/24: Supervisory Net
▪ 10.0.30.0/24: Control Net A
▪ 10.0.40.0/24: Control Net B
▪ 10.0.50.0/24: Upstream Net

Segmentation Done
▪ Segmentation using (V)LANs
▪ Units devided into groups based on role
▪ Each group in separate segment (zone)
▪ Within segment, communication
typically switched
▪ Across segments, routed via
Firewall/Router
▪ ”Default gateway” setting adds route
towards Internet
▪ Firewall not enabled
▪ All units can still communicate
▪ Security not (yet) enhanced
▪ Next step: Traffic segregation!

Traffic Segregation using Firewall
▪ Block all traffic by default
▪ ”Default forward policy”: Deny
▪ No traffic will be routed between LANs!
▪ Add ”packet filter allow” rules for legal traffic flows
▪ Whitelisting
▪ Need to learn your traffic patterns
▪ Example:
▪ Office network gets access towards Internet
(perhaps only HTTPS and DNS)
▪ No communication between Control Networks
▪ Supervisory Network can access Control
Networks
▪ Limit to specific sources/destinations and protocols
▪ Complements to Firewall packet filters
▪ Stateful Inspection
▪ Deep inspection firewall

Firewall filter rules in WeOS
▪ Default ”Forward Policy”: Drop
▪ Add ”Filter allow” rules for whitelisting allowed traffic
patterns
▪ Match traffic based on
▪ Network Interface (in/out)
▪ IP address (src/dst)
▪ IP payload protocol (TCP, UDP, ICMP, ...)
▪ TCP or UDP Port number
▪ Stop at first match (action: allow or deny/drop)
▪ Input or Forward chain?
▪ Input chain: Rules without ”Out Interface” and
”Destination address”
▪ Forward chain: Rules with ”Out Interface” and/or
”Destination address”
▪ Stateful firewall
▪ Logging possible
▪ Note: Does not apply to switched traffic
45. 45
Firewall filter configuration example
▪ Add ability for management station in supervision
network to control a unit in control network A via
SNMP.
▪ Here we limit to specific IP addresses of
management station (10.0.20.5) and the controlled
unit (10.0.30.33).
