Musings on the intersection of biology and information security.

1. All That’s Old Is New

2. Pay Attention To History Or Repeat
It
Biology - Too Much Data
A Problem of Scale

3. Pay Attention To History Or Repeat
It
Biology - Mendel (1856)
Father of genetics/heredity

4. Structure From Noise
Biology - Watson and Crick* (1953)
Discovered Structure of DNA
* not without controversy

5. Structure From Noise
Genotype - whether or not you carry gene(s)
that manifest the characteristic
Phenotype - Physical/Observable traits
...Blue eyes

6. Structure From Noise
hypothetical analogue:
program structure = genotype
init - subroutine1 - sub2 - sub3
A - T - G - C - … X - Y - Z

7. Structure From Noise
hypothetical analogue:
sandbox activity = phenotype
writefile - resolvedns - openconnection
A - T - G - ...

8. Structure From Noise

9. Kinda Sorta The Same
Similarity Searching:
Locality Sensitive Hashing
Perceptual Hashing

10. Kinda Sorta The Same
Similarity Searching:
Traditional Hash: low collisions, hard to
reverse, small ∆input = large ∆output
LH/pHash: small ∆input = small ∆output

11. Not All That Glitters
Going In The Other Direction:
Applying Information Theory to Biology
Could it apply to DLP?

12. Thanks
