Business continuity and disaster recovery (BCDR) basics
1. Business continuity and disaster recovery (BCDR) basics
Knowing how to respond to a crisis is a valuable skill in cloud security. In this video, we’ll explore an area that is critically important for any cloud-based operation: business continuity and disaster recovery, or BCDR tools. Let's get started. So, what's BCDR all about? Simply put, business continuity and disaster recovery are like a safety net. They’re critical in security operations because they ensure that when disaster strikes, business operations are active, and data remains safe and accessible. There's a variety of BCDR tools available to Security Operations teams, each with its unique purpose. These tools can range from BCDR plan builders, and backup and restore utilities to sophisticated software that handles data center failovers. And all these BCDR tools all share a common goal: to protect your business from the negative effects of a disaster. These tools can also help you make and execute a plan to restore your systems and get data back online. They ensure you can continue normal operations and continue serving your users without any interruption. So, no matter the size or scope of the problem, there’s a BCDR tool available to help. Now, let's explore BCDR in Google Cloud. Google Cloud offers BCDR tools designed specifically for its cloud environment to assist with regular backup and recovery operations. As a security professional, Google Cloud BCDR tools help with key aspects of business continuity and disaster recovery. For example, you can test and establish backup and recovery processes, test data management, and verify a documented backup plan. Here’s an example. Imagine your team can’t mitigate a ransomware attack in time. Multiple systems are affected, so you need to utilize backup and disaster recovery tools to restore normal operations. Before you begin the process of restoring the affected systems, you need to prioritize the restoration of critical business systems. First, you isolate the affected system —like a server or virtual machine— and terminate the ransomware task. Then, you restore the system to the most recent recovery point from the last unaffected backup. By using cloud-based BCDR tools, your security operations team can be confident that completely different infrastructure is in use, rather than a compromised network. Once the new system is running, the security team connects the recovered system to the network, so that end users can return to work, and operations can continue. So remember, these BCDR tools are not just pieces of software, they're what you can use to ensure your business continues to run smoothly and efficiently during disaster recovery.2. Let's practice!
