Which service provides functionalities like intrusion detection and anti-malware in the cloud?

  1. Software as a Service (SaaS)

  2. Infrastructure as a Service (IaaS)

  3. Security as a Service (SECaaS)

  4. Container as a Service (CaaS)

The correct answer is: Security as a Service (SECaaS)

The choice of Security as a Service (SECaaS) is accurate because it specifically focuses on providing security services over the internet. SECaaS encompasses a variety of security functionalities, including intrusion detection, anti-malware protection, and more. These services are typically managed and hosted by a third-party provider, allowing organizations to leverage advanced security technologies without the need to maintain their own in-house solutions. This can lead to cost savings and access to more sophisticated security measures than what many organizations could afford or manage effectively on their own. Additionally, the flexibility of SECaaS allows businesses to scale their security measures in accordance with their needs, which is crucial in a cloud environment where threat landscapes can change rapidly. By offloading these security functions to a dedicated service, companies can focus their resources on core business activities while benefiting from enhanced protection against cyber threats.
