In January and February of 2021, the threat actor called Hafnium used a number of post-exploitation tools after gaining access to Exchange servers through a zero-day exploit. One of their persistence methods was creating new user accounts in the domain, giving them the ability to log back into the network using normal authentication rather than use a web shell or continue to re-exploit the vulnerability (which has since been patched).

The biggest fundamental shift in the era of digital transformation is that data is no longer on a CPU that the enterprise owns. Security teams focused on cloud must invest in the right technology to achieve more complete data protection, and we all need to ensure Zero Trust principles are applied everywhere data needs protection. At Netskope, we describe this as Zero Trust Data Protection. In its simplest form, Zero Trust means: Don’t trust the things you do not need to trust.

“Where necessity speaks, it demands”. This old saying seems particularly apt right now with the pandemic forcing organizations to completely change the way they think about their IT networks. That rapid shift to remote work has resulted in a massive demand for cloud-based services.

GCP audit logs are a powerful tool that track everything happening in your cloud infrastructure. By analyzing them, you can detect and react to threats. Modern cloud applications are not just virtual machines, containers, binaries, and data. When you migrated to the cloud, you accelerated the development of your apps and increased operational efficiency. But you also started using new assets in the cloud that need securing.

Lateral movement is a growing concern with cloud security. That is, once a piece of your cloud infrastructure is compromised, how far can an attacker reach? What often happens in famous attacks to Cloud environments is a vulnerable application that is publicly available can serve as an entry point. From there, attackers can try to move inside the cloud environment, trying to exfiltrate sensitive data or use the account for their own purpose, like crypto mining.

Implementing effective threat detection for AWS requires visibility into all of your cloud services and containers. An application is composed of a number of elements: hosts, virtual machines, containers, clusters, stored information, and input/output data streams. When you add configuration and user management to the mix, it’s clear that there is a lot to secure!
