Vulnus: Visual Vulnerability Analysis for Network Security
IEEE Transactions on Visualization and Computer Graphics
|August 24, 2018
Summary
VULNUS is a visual analytics tool that helps network security managers understand and manage IT system vulnerabilities. It identifies optimal patching strategies to eliminate attack paths, improving network security posture.
Area of Science:
- Computer Science
- Information Security
- Data Visualization
Background:
- IT systems face significant weaknesses due to vulnerabilities.
- Official data like Common Vulnerabilities and Exposures (CVE) aids in identifying potential attack paths.
- Implementing patches is often hindered by business constraints and resource limitations, complicating vulnerability management.
Purpose of the Study:
- To present VULNUS, a visual analytics solution for dynamic inspection of network vulnerabilities.
- To enable a rapid understanding of network security status and visually classify nodes based on vulnerability levels.
- To compute optimal and explore sub-optimal patching sequences to mitigate attack paths.
Main Methods:
- Developed VULNUS, a visual analytics system for network vulnerability assessment.
- Implemented algorithms to compute approximated optimal and sub-optimal patching strategies.
- Conducted a lab-test experiment with domain experts for evaluation.
Main Results:

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

01:25Network Function of a Circuit
791
Frequency response analysis in electrical circuits provides vital insights into a circuit's behavior as the frequency of the input signal changes. The transfer function, a mathematical tool, is instrumental in understanding this behavior. It defines the relationship between phasor output and input and comes in four types: voltage gain, current gain, transfer impedance, and transfer admittance. The critical components of the transfer function are the poles and zeros.

A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...
