RSRS Study Outline Model of self-regenerative systems

Analysis and meta-model based on feedback/reflection: (MLA) loop

Comparison of SRS projects (by area) Event-based core functional interfaces

Self-regenerative (MLA) functionality Area-specific functionality

Project-specific capabilities Synthesis and integration of interfaces

Core Functional Interface Comparison by Area

Core functionality for each area Self-regenerative (MLA) functionality

Cognitive immunity and self-healing Reasoning about insider threats

Area-specific functionality Biologically-inspired diversity Granular, scalable redundancy

Project-specific capabilities

10

Biologically-Inspired Diversity Interfaces

Self-regeneration (MLA) functionality Test and evaluation environment

Area-specific functionality Create diverse representations of

programs in response to known and unknown attacks

Provide a “measure” of diversity (estimated degree of resistance to known attacks)

Project-specific functionality

11

Cognitive Immunity and Self-Healing Interfaces

Self-regeneration (MLA) functionality Monitor interface: evaluate the defensive

actions during attacks on applications Learning interface: match attacks and

defenses (diverse code generation tools) Regeneration Actuator interface: replace

vulnerable code Area-specific functionality Project-specific functionality

Learn/Repair: embedded data structure repair tools

12

Granular, Scalable Redundancy Interfaces

Self-regeneration (MLA) functionality Regeneration in multicast, gossip protocols

Area-specific functionality Redundant communication services

(pub/sub, multicast) Redundant event processing Redundant object management services

Project-specific functionality

13

Reasoning About Insider Threats Interfaces

Self-regeneration (MLA) functionality Monitor interface: detect potential/actual

insider threats Learning interface: refine detection and

guide adaptive responses Regeneration Actuator interface:

implement adaptive policies in response Area-specific functionality Project-specific functionality
