A cloud services provider is responsible for ensuring its own infrastructure and applications are secure, but that doesn’t mean cloud resources are automatically protected against cyberthreats. Insider threats, hijacked accounts, distributed denial-of-service (DDoS) attacks and advanced malware still pose viable risks to cloud-based assets, and can disrupt business operations and harm important data.
Leading cloud providers such as Amazon Web Services (AWS) have developed resources to help businesses monitor data traffic and cloud-network activity. However, the onus is still on the customer to manage those resources. Furthermore, cloud vendors aren’t required to provide integration with other cloud services, or with on-premises IT assets. This makes it very challenging to develop a security information and event management (SIEM) resource.
A SIEM is crucial for centralization of all log data. Even outsourced security resources such as SaaS-based antivirus, firewall, endpoint detection and response, as well as application controls must be able to share data with a central management console. Likewise, data that lives with an IaaS provider, such as AWS, must consolidate in a single point of reference where it can undergo continuous threat monitoring.
In short, all network traffic must be brought together in one place so it can be monitored and, if necessary, subjugated to incident response. For enterprises with limited budgets and security expertise, however, that’s much easier said than done.
SOC-as-a-service: The unifying factor
The reason many companies gravitate toward cloud services is to reduce complexity. This lets them then focus on improving their business operations and serving customers better. Trying to build a SOC that is capable of unifying mixed cloud resources, let alone staffing it 24/7 with security experts, is anything but simple–and it certainly isn’t cost effective.
Conversely, outsourcing to a cloud-based SOC-as-a-service provider frees up resources so businesses can make the most of their public, private or hybrid cloud deployments without any additional cost and complexity.
For this reason, there is a very clear answer to the question of on-premises or as-a-service cloud-security management: SOC-as-a-service.
