The DevOps environment has been changing rapidly, and adaptive security has become a widely used response to this. The main purpose of adaptive security is to create layers of security providing threat detection, visibility, and prevention that continue to evolve and become better.
The term “Adaptive Security Architecture” was created in 2008 by Sun Microsystems, which was acquired by Oracle in 2010. It was designed to anticipate and respond to threats, all while reducing threat amplification, velocity, attack surface, and the recovery time. This is an architectural model that imitates a biological immune system from a microscopic level.
Biological systems are designed to respond to changing conditions and adapt. They are able to respond to threats in a dynamic way, which mimics the involuntary immune system response. These systems are made of several components that are not dependent on one entity in order to survive.
Adaptive security is a type of security mode that monitors threats continuously and improves as threats change and evolve. With traditional security methods, organizations use firewalls, intrusion defense systems (IDS), antivirus software, and intrusion prevention systems (IPS). In truth, while they are a powerful defense, they are no longer enough. Environments are no longer static, and security systems should be integrated within continuous deployment IT.
The main benefit of adaptive security is for early detection of threats and an automatic and autonomous response for any malicious event. Other benefits include:
- Containing threats when they occur.
- Preventing the theft and sabotage of data.
- Reducing time dwelled on threats.
- Stopping the spread of a pandemic.
- Recognizing ongoing security breaches.
- Avoiding a monoculture systems environment.
Adaptive security is designed to evolve and be more complex in order to defend against evolving security threats.
There are four stages in adaptive security architecture:
- Predict: To assess the risk and anticipate malware and attacks, then implement the baseline systems.
- Prevent: To isolate and harden systems, thus preventing security breaches.
- Respond: Investigating incidents and designing policy changes, plus conducting a retrospective analysis.
- Defect: Prioritizing risks and defects and learning how to contain threats and incidents.
Combining these four stages creates a system with the ability to respond to suspect behaviors.
For an effective adaptive security system, they require a robust solution that incorporates different features and measures to predict threats and ensure a comprehensive network, as well as endpoint protection.
A proactive approach to security enables organizations to adapt to ever-changing threats. And this is exactly what adaptive security provides.
