Staffing and resources – Organizations already struggling to keep their security teams fully staffed are facing even greater challenges as they adopt cybersecurity tools to address today’s threats. Most organizations have cybersecurity tools they don’t have time to manage themselves. The investment organizations might have made in leading-edge technologies can end up hurting instead of helping them, especially expertise and the human time element.
Alert Fatigue – The challenge is managing massive numbers of alerts. This isn’t a problem unique to cybersecurity, but it is made significantly worse as the number of exploits and vulnerabilities grows with the number of devices and networks. This is particularly difficult with smart devices or IoT devices being a part of everyday workplaces. Determining how to respond to or contain each alert requires more manpower and expertise than is typically available, whether in-house or outsourced services with partners. When a threat is significant, an organization needs the relevant skills to remediate it and return to business as usual.
Containing Threats – This step aims to halt the effects of an incident before it can cause further damage. Actions might include disconnecting systems from networks, quarantining infected systems, or blocking traffic to and from known malicious IP addresses.- Often, because this involves operational systems being halted, this step is the most expensive and time-consuming. Though this varies from business to business, it always has associated economic downtime.
An MDR remotely monitors, detects, and responds to threats determined and detected within your organization. An XDR tool typically provides the necessary visibility into security events in your organization. When you give the right kinds of analytics with enough information or data, the human element can now perform the necessary elements.
The most expensive and difficult part of MDR or XDR is the complexity and knowledge needed by the human element in every environment.
To best understand the complete value of MDR or XDR, it is important to understand what are commonly accepted as the six steps of a cybersecurity incident response plan:
