An intrusion detection system (IDS) provides threat detection and alerting to support incident response activities. Cloud IDS is a cornerstone of a solid cloud security strategy.
A cloud IDS is an IDS deployed in a cloud-native form factor to monitor both on-prem and cloud-based assets as part of a cloud-delivered security strategy, or to protect cloud-based resources under a IaaS security model.
An IDS is a cybersecurity solution designed to identify and alert on cyber threats. An IDS can be host-based or network-based, and a network-based IDS can be deployed inline or listen on a network tap. An IDS can use a combination of signature-based and anomaly-based detection to identify potentially malicious communications or access attempts within network traffic. If an IDS detects suspicious traffic, it generates an alert sothe security team can respond to it in a swift and timely manner.
An IDS differs from an intrusion prevention system (IPS) in that an IDS only provides a warning of potentially malicious activity with no attempt to block or remediate it. An IPS, on the other hand, can block suspected attacks before they enter the corporate network.
A cloud IDS can be deployed in a few different service models. Cloud IDS can be deployed independently as a Software as a Service (SaaS) offering or as part of a next-generation firewall as a service (Next Generation FWaaS), a cloud-based FWaaS for IaaS environments, or a Secure Access Service Edge (SASE) solution, which combines SD-WAN functionality with a full network security stack (including IDS) in a cloud-based solution.
Cloud-based and on-premises IDS have the same purpose: to inspect network traffic and alert on potentially suspicious or malicious content. They differ in how they are deployed and what portion of the organization’s infrastructure they protect.
A cloud IDS is typically deployed as a standalone solution, part of integrated security solutions for branch access, remote user access, or cloud data centers and production environments (IaaS), or consumed via a service-based model. Often, these tools take advantage of virtual network taps provided by cloud providers to monitor traffic to and from the cloud environment. On-premises IDS can be deployed as a virtual or physical appliance. These solutions work similarly to a cloud IDS but provide protection solely to an organization’s on-prem environment.
A cloud IDS is essential for threat detection and incident response in cloud environments. Some key features of a cloud IDS include:
Painless Deployment: Cloud IDS are deployed as virtualized appliances or via a service-based model. This makes it easy to quickly deploy new solutions to address evolving business needs.
A cloud IDS enables an organization to effectively and scalably detect potential threats to their cloud-based deployments. Cloud IDS provides significant benefits to an organization, including:
Cloud IDS provides an organization with the ability to detect cyber threats and provides vital alerts to security personnel for incident response. Cloud IPS goes a step further to block identified threats before they enter an organization’s cloud environment and pose a risk to corporate data storage and applications.
SASE solution, provides integrated threat prevention, with embedded cloud IPS and DLP, to secure remote access with a single, cloud-native solution.
