Cloud IDS
1. Cloud IDS
Let’s talk briefly about another Google Cloud security offering—Cloud IDS. Quinn, a network engineer at Cymbal Corporation, is looking for a way to improve the security of the company's cloud infrastructure. Cymbal has observed a concerning rise in cyberattacks targeting sensitive customer and financial data. These attacks range from unauthorized access attempts to the delivery and execution of malicious software. Additionally, covert monitoring tools and command-and-control attacks attempting to establish communication channels between compromised systems and external servers have been detected. Such threats pose a substantial risk to Cymbal's reputation, customer trust, and regulatory compliance, underscoring the urgent need for advanced security measures. Solution To mitigate these escalating cyber threats, Cymbal has implemented Google Cloud IDS. Cloud IDS is a network security service offered by Google Cloud that provides real-time detection of intrusions, malware, spyware, and command-and-control attacks. With comprehensive monitoring of both internal and external traffic, Cloud IDS offers Cymbal improved visibility into their network and system vulnerabilities. The scalability of the service allows Cymbal to adapt their threat detection capabilities as their infrastructure expands. As a fully managed service, Cloud IDS simplifies security management, enabling Cymbal's IT team to focus on other priorities while ensuring the safeguarding of their critical assets. Cloud IDS is an intrusion detection service that provides threat detection for intrusions, malware, spyware, and command-and-control attacks on your network. Cloud IDS works by creating a Google-managed peered network with mirrored VMs. Traffic in the peered network is mirrored, and then inspected by Palo Alto Networks threat protection technologies to provide advanced threat detection. Cloud IDS provides full visibility into network traffic, including both north-south and east-west traffic, letting you monitor VM-to-VM communication to detect lateral movement. Cloud IDS provides full visibility into network traffic, including both north-south and east-west traffic, letting you monitor VM-to-VM communication to detect lateral movement. Cloud IDS gives you immediate indications when attackers are attempting to breach your network, and the service can also be used for compliance validation, like PCI 11. In addition, Cloud IDS automatically updates all signatures without any user intervention, enabling users to focus on analyzing and resolving threats without managing or updating signatures. To better understand Cloud IDS, it’s important to understand how the service uses endpoints and packet mirroring. Cloud IDS uses a resource known as an IDS endpoint, a zonal resource that can inspect traffic from any zone in its region. Each IDS endpoint receives mirrored traffic and performs threat detection analysis. Cloud IDS uses Google Cloud packet mirroring, which creates a copy of your network traffic. After creating an IDS endpoint, you must attach one or more packet mirroring policies to it. These policies send mirrored traffic to a single IDS endpoint for inspection. The packet mirroring logic sends all traffic from individual VMs to Google-managed IDS VMs. For example, all traffic mirrored from VM1 and VM2 will always be sent to IDS-VM1.2. Let's practice!
