Understanding Policy Orchestration in Cybersecurity

Defining Policy Orchestration

• 🎯 Policy orchestration is defined as the deployment of rules across an organization's security stack, encompassing all data islands, cloud services, SaaS applications, data centers, and mobile devices.
• 💡 Its primary goal is to manifest an organization's cybersecurity first principle strategies, such as zero trust, intrusion kill chain prevention, resilience, and risk forecasting.
• ⚙️ The term "policy" refers to a set of rules adopted organization-wide, while "orchestration" signifies an automated series of processes to configure, coordinate, and manage computer systems, data, or software.

Evolution of Security Management

• ⏳ In the early internet days (late 1990s), managing security policies was simpler with only a few tools like firewalls, intrusion detection systems, and antivirus software.
• 🛠️ Policy changes required manual login and configuration on each individual tool.
• 🚀 Today's environments are vastly more complex "systems of systems" deployed across multiple data islands, making consistent and rapid policy deployment challenging.

The Goal of Policy Orchestration

• 🔑 The objective of policy orchestration is to establish a centralized location for configuring security policies.
• ⚡ This enables the automatic deployment of prevention and detection controls to every tool in the security stack across all data islands, aiming for completion in minutes to hours rather than days or weeks.
• 📈 Achieving this goal efficiently and quickly is crucial for modern cybersecurity programs.

Approaches to Implementation

• 🧩 Organizations can achieve policy orchestration through various tactics, including integrating it into DevSecOps processes.
• 💻 Alternatively, they might adopt commercial orchestration platforms, utilize their existing SOAR (Security Orchestration, Automation, and Response) tools, or outsource the task to SaaS (Secure Access Service Edge) or SSE (Security Service Edge) vendors.
• ✅ Regardless of the method, mastering policy orchestration is presented as a key and essential task for all information security programs.

Benefits in Practice

• 📊 David Monahan from EMA Research highlighted the advantage of standardizing firewall policies across multiple vendors using security policy automation and orchestration (SPOA).
• 🖱️ This eliminates the need to use multiple graphical user interfaces (GUIs) for different vendor firewalls, allowing for single management capabilities.
• 🌐 SPOA is particularly beneficial for managing firewalls in heterogeneous environments.
