Lessons from Biological Security
The biological world is also open source in the sense that threats are always present, largely unpredictable, and always changing. Because of this, defensive measures that are perfectly designed for a particular threat leave you vulnerable to other ones. Imagine if our immune system were designed to deal only with a single strain of flu. In fact, our immune system works because it looks for the full spectrum of invaders low-level viral infections, bacterial parasites, or virulent strains of a pandemic disease. Too often, we create security measures such as the Department of Homeland Security’s BioWatch program that spend too many resources to deal specifically with a very narrow range of threats on the risk spectrum.
Advocates of full-spectrum approaches for biological and chemical weapons argue that weaponized agents are really a very small part of the risk and that we are better off developing strategies like better public-health-response systems that can deal with everything from natural mutations of viruses to lab accidents to acts of terrorism. Likewise, cyber crime is likely a small part of your digital-security risk spectrum.
A full-spectrum approach favors generalized health over specialized defenses, and redundancy over efficiency. Organisms in nature, despite being constrained by resources, have evolved multiply redundant layers of security. DNA has multiple ways to code for the same proteins so that viral parasites can’t easily hack it and disrupt its structure. Multiple data-backup systems are a simple method that most sensible organizations employ, but you can get more clever than that. For example, redundancy in nature sometimes takes the form of leaving certain parts unsecure to ensure that essential parts can survive attack. Lizards easily shed their tails to predators to allow the rest of the body (with the critical reproductive machinery) to escape. There may be sacrificial systems or information you can offer up as a decoy for a cyber-predator, in which case an attack becomes an advantage, allowing your organization to see the nature of the attacker and giving you time to add further security in the critical part of your information infrastructure.
