With the advent of the cloud and DevOps, the job of implementing security has been dispersed more widely across IT. This has led to significant gains in speed and agility, but it has also created unacceptable risk for the business. For security, the pendulum has swung too far toward democracy. We need to pull it back.
It's easy to forget that as recently as a decade ago, IT in a pre-virtualization/pre-cloud world looked very different from today. Software projects were measured in months if not years, and security teams had control and visibility over all that went out the door. This ensured less risk, but as dev teams tried to move faster, security quickly became the infamous "department of no." If CSOs weren't banning projects outright, they were certainly holding them up to ensure every possible door to a vulnerability was closed.
DevOps is a great frontier by comparison. These days, software and infrastructure teams are implementing new features and services at a remarkable place, aided by higher-level tools and a myriad of third-party services in the cloud. Just this past year alone, swift advances in areas like containers and serverless computing have allowed dev teams to do far more with less.
It would be unfair to say developers aren’t attuned to the needs of security — the constant drumbeat of major breaches means that everyone is now aware of the need to lock down applications and data. And the major cloud providers have invested heavily to secure their infrastructure and provide built-in tools and protocols for securing data and connections.
But this is precisely the challenge. As DevOps turns to these off-the-shelf mechanisms to secure applications, they fall prey to an illusion of security. That's not a criticism of cloud providers; it merely reflects the reality that security in the enterprise is highly complex. Organizations develop security policies for a reason. Not all data is equal, and highly sensitive information, such as customer or financial data, must be afforded higher levels of protection.
Networks and systems are also complex, and potential attack vectors aren't always apparent when applications are built quickly and modified frequently over time. Security experts need a front-row seat in the DevOps process, because they are the individuals uniquely trained to identify these vulnerabilities. But in the democratic model of security, their role is too often reduced.
Clearly, we do not want to roll back the advances of recent years and inhibit the ability of dev teams to innovate quickly. But developers, ops, and security teams must each acknowledge their respective areas of expertise and work together to ensure that the risks inherent to moving quickly without sufficient care are mitigated.
Security must not be a bottleneck, but the democratization of security through DevOps has been an overcorrection to the time when security had absolute control. If the right model for security is not a pure democracy, where everyone has an equal say in policy and no one is ultimately responsible, then we should think of it more as a representative democracy — where power resides in the people, but that power is exercised through elected representatives.
What does this imply for application development, IT operations, and security governance? That the elected security representative — the CSO — is accountable to the organization and therefore carries out its will (no more "department of no"). But the CSO also has authority to decide how that will should be implemented, because ultimately, it's the CSO who is accountable for keeping the business secure.
Getting to the model of a representative democracy requires a change in how security, dev, and ops teams work together today. Here are three best practices to help make this happen.
Automation, virtualization and the cloud have brought sweeping changes to how applications are developed and delivered. IT is a far more exciting and dynamic place to be than it was just a decade ago, and technologists have far more impact on the success or failure of business. But that also brings new levels of responsibility. A single security incident can affect the valuation of an entire company. Dev teams and security staff must work together to ensure this does not happen.
