Boy from chat avenue adult chat masturbating on cam - Validating and restoring defense in depth using attack graphs

Previous work introduced the idea of grouping alert s at a Hamming distance of 1 to achieve lossless al ert aggregation; such aggregated meta-alerts were shown to increase alert interpretability.

However, a mea n of 84023 daily Snort alerts were reduced to a still formidable 14099 meta-alerts.

We measure depth and width through solving the shortest color path and minimum color cut problems.

This paper presents an approach based on Boolean Satisfiability Solving (SAT Solving) that can reason about attacks, usability requirements, cost of actions, etc. Preliminary results show that the approach is both effective and efficient.

Past work has provided ways to identify intricate attack paths due to misconfiguration and vulnerabilities in an enterprise system, but little has been done to address how to correct the security problems within the context of various other requirements...

This paper presents GARNET (Graphical Attack graph and Reachability Network Evaluation Tool), an interactive visualization tool that facilitates attack graph analysis.

Springer, Berlin, Heidelberg Attack graphs enable computation of important network security metrics by revealing potential attack paths an adversary could use to gain control of network assets.

Defense-in-depth is an important security architecture principle that has significant application to industrial control systems (ICS), cloud services, storehouses of sensitive data, and many other areas.

We claim that an ideal defense-in-depth posture is 'deep', containing many layers of security, and 'narrow', the number of node independent attack paths is minimized.

Consider the following; knowledge skills and abilities as required to hire information security professionals rely heavily on technology attributes; vendor solutions are implicitly if not explicitly technology related; the relation of technology to the security domain is nearly exclusively a computer issue.

The foregoing being true may result in a substantial examination of the problem but it leaves the human factor area untended.

(2008) GARNET: A Graphical Attack Graph and Reachability Network Evaluation Tool. It allows users to perform “what-if” experiments including adding new zero-day attacks, following recommendations to patch software vulnerabilities, and changing the attacker starting location to analyze external and internal attackers.
