Module review
1. Module review
This module covered definitions and mitigations for a very serious threat to businesses: DDoS attacks. Here’s an overview of what was discussed: A distributed denial-of-service, or DDoS, attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network. These attacks work by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic from multiple sources - most often using ‘zombie computers’ that have been compromised. Armies of infected computers, known as “botnets”, can be huge and can include millions of computers. DDoS mitigation requires a multi-layered set of strategies. These include: load balancing, reducing attack surface, isolating internal traffic, monitoring APIs to detect and throttle malicious traffic, using CDNs to isolate and serve content, and finally, the use of third-party resources for specific needs. Google Cloud provides tools to execute these strategies, including load balancing, VPCs for isolation, Cloud Endpoint or Apigee to create API management gateways, Cloud CDN for serving content from the edge to the outside, and Google Cloud Armor for at-scale defense of your applications and operations. Third-party options are also available that complement Google Cloud products. Different categories of third-party security in the ecosystem include infrastructure protection partners, data protection partners, monitoring and logging partners and vulnerability, risk and compliance partners. Refer to the link in this module’s course resources for a more detailed, current list of partners. The next module covers another important security topic: content-related vulnerabilities.2.
