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.

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!

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).

2. Carbon The element of LIFE! Found in all living organisms! We are always looking for carbon based life forms Organic molecules: molecules that contain carbon C6H12O6, CO2, CH4 Some molecules are made of just CARBON and HYDROGEN…we call these HYDROCARBONS These are important in FUEL (aka GASOLINE!!) Many organic molecules, such as fats, have hydrocarbon components Hydrocarbons can undergo reactions that release a large amount of energy Inorganic molecules: molecules that do not contain carbon H2O, NH3, O2
4. Structure of Carbon Structure Valence electrons: 4 How many bonds can carbon make with other atoms? 4: single, double, or triple…as long as it has 4 lines touching it This makes carbon a versatile atom…it can make long chains of carbons, branched carbon structures, even ring structures with itself
5. LE 4-5 Propane Ethane Length 2-methylpropane (commonly called isobutane) Butane Branching 1-Butene 2-Butene Double bonds Cyclohexane Benzene Rings
6. Some important words to know Molecule Group of covalently bonded atoms Macromolecule large molecules composed of thousands of covalently connected atoms Functional Groups Group of atoms within a molecule that interact in PREDICTABLE ways Polar, non-polar, acidic, basic, charged (+/-) Hydroxyl group Carbonyl group Carboxyl group Amino group Sulfhydryl group Phosphate group
10. LE 4-10aa STRUCTURE (may be written HO—) Ethanol, the alcohol present in alcoholic beverages NAME OF COMPOUNDS FUNCTIONAL PROPERTIES Is polar as a result of the electronegative oxygen atom drawing electrons toward itself. Alcohols (their specific names usually end in -ol) Attracts water molecules, helping dissolve organic compounds such as sugars (see Figure 5.3).
11. LE 4-10ac EXAMPLE STRUCTURE Acetic acid, which gives vinegar its sour taste FUNCTIONAL PROPERTIES NAME OF COMPOUNDS Has acidic properties because it is a source of hydrogen ions. Carboxylic acids, or organic acids The covalent bond between oxygen and hydrogen is so polar that hydrogen ions (H+) tend to dissociate reversibly; for example, Acetic acid Acetate ion In cells, found in the ionic form, which is called a carboxylate group.
12. LE 4-10ba EXAMPLE STRUCTURE Glycine Because it also has a carboxyl group, glycine is both an amine and a carboxylic acid; compounds with both groups are called amino acids. FUNCTIONAL PROPERTIES NAME OF COMPOUNDS Acts as a base; can pick up a proton from the surrounding solution: Amine (nonionized) (ionized) Ionized, with a charge of 1+, under cellular conditions
13. LE 4-10bc EXAMPLE STRUCTURE Glycerol phosphate NAME OF COMPOUNDS FUNCTIONAL PROPERTIES Makes the molecule of which it is a part an anion (negatively charged ion). Organic phosphates Can transfer energy between organic molecules.
22. Three of the four classes of life’s organic molecules are polymers:Carbohydrates Proteins Nucleic acids ***Lipids/fats are not polymers but they are still macromolecules
27. Making and Breaking Polymers Polymerization:making polymers Dehydration Reaction Dehydrate means water loss When a water molecule (H-OH) is released to join a monomer to another monomer Hydrolysis Hydro- water Lysis- to break down Def: to break apart or disassemble a polymer by adding water (H-OH)
28. LE 5-2 Short polymer Unlinked monomer Dehydration removes a water molecule, forming a new bond Longer polymer Dehydration reaction in the synthesis of a polymer Hydrolysis adds a water molecule, breaking a bond Hydrolysis of a polymer
29.
30. Carbohydrates Monomer: Monosaccharide Polymer: Disaccharide or Polysaccharide Link between monomers is called: Glycosidic Linkage Formed by a dehydration reaction Always have Carbon, Hydrogen, and Oxygens CxH2xOx Common name: sugar End with suffix “-ose” Function: Energy/fuel, structure, storage GLUCOSE!!!! What all cells need for energy
31. Carbs continued Monosaccharides Glucose fructose Disaccharides sucrose Polysaccharides Starch In plant cells; chain of glucose molecules coiled up like a phone cord Glycogen Excess sugar in animal cells is stored in this form; highly branched and more complex chain of glucose monomers Stored in muscle and liver cells When body needs energy, glycogen is broken down into glucose Cellulose Found in plant cell walls; made of glucose monomer; building material; aka FIBER; humans do NOT have the enzyme to break this polysaccharide down Passes through digestive tract and keeps it healthy but NOT a nutrient Some animals (cows) have microorganisms that live in their digestive tract that help break down cellulose Carbs are hydrophilic because of hydroxl group (-OH) Dissolve in water making sugary solutions Large carbs (starches and cellulose) do not dissolve Think about your towels and clothes, duh!
32. Proteins Monomer: amino acids 20 amino acids Amine (NH2) and carboxyl (COOH) groups attached to carbon Only thing different is side chain…R-group Polymer: polypeptide chains (proteins) Link between monomers is called: polypeptide bond Made by a dehydration reaction (between amine group of one aa and carboxyl group of another aa) STRUCTURE of A.A. Amino group on one end (-NH2) Carboxyl group on one end (COOH) Hydrogen R-group/side chain (changes) Function of Proteins: structural support Storage Transport cellular communications Movement defense against foreign substances Proteins account for more than 50% of the dry mass of most cells
33.
34. Protein Structure Primary structure 1’ Order of amino acids in a polypeptide chain Secondary structure 2’ Polypeptide chain folds because of interactions between amino acids HYDROGEN BONDING Tertiary Structure 3’ Gives proteins 3-D shape VERY IMPORTANT to function of protein Beta pleated sheets and alpha helices fold based on interactions between R-groups of a.a. Hydrogen bonds, polar/non-polar interactions, acid/base interactions, disulfide bonds, van der Waals forces Quaternary Structure 4’ the association of the polypeptide chains some proteins contain more than one polypeptide chain Each polypeptide chain in the protein is called a subunit Two or more subunits come together for a specific function HEMOGLOBIN On Red blood cells Its shape allows RBCs to carry oxygen all around your body!
35. Denaturation Unraveling/unfolding of protein Why would this be a problem? When protein loses its 3-D shape and thus its specific function Caused by: Unfavorable changes in pH, temperature or other environmental condition Disrupts the interactions between side chains and causes loss of shape Examples: Frying an egg Straightening your hair
36.
37.
38. Fats/Lipids Made of mostly carbon and hydrogen…some oxygen Usually not soluble in water Not a polymer but is made of molecular units Glycerol + 3 Fatty Acids= FAT Linkage is called ESTER linkage Dehydration reaction Function Energy storage Insulation waterproofing
39. Types of Fats Saturated Solid at room temperature Animal fats All the carbons in the fatty acid chains contain the MAXIMUM # of hydrogen atoms around each atom SATURATED with hydrogen Only single bonds in fatty acid chain Unsaturated/polyunsaturated fats Liquid at room temperature Plant oils, fish oils One or more double bonded carbon atoms in fatty acid chain, then it is unsaturated
41. Steroids Chemical messengers Structure 4 fused carbon rings Ex. Cholesterol, testosterone, estradiol Function structural component of mammalian cell membranes resilience and fluidity of human membranes mobilized for the synthesis of steroid hormones protecting the human skin against external irritants and for holding water content Improvement of water balance in human skin Enhanced barrier function for stratum Inhibition of aging of skin Water retention for hair
