Netenrich designed Resolution Intelligence Cloud to enable proactive and continuous detection and response that helps minimize the impact of security incidents.
When it comes to cybersecurity, what is detection and response?
The key components of effective detection and responses system typically include a combination of technology, processes, and human expertise. More specifically, components include continuous monitoring, detection and response tools, log management and analysis, threat intelligence integration, behavioral analytics, automation and response orchestration, and effective collaboration, communication, and reporting.
How can continuous detection and response help protect businesses?
Continuous detection and response (CDR) is part of a proactive cybersecurity strategy that recognizes the dynamic nature of cyber threats — in short, threat actors are innovative and relentless — and aims to minimize the impact of security incidents through rapid identification and response. CDR solutions monitor network traffic, system logs, and other relevant data sources to identify potential security incidents in real-time then seamlessly integrate the potential incident with other security tools and technologies to include threat intelligence feeds, which help organizations stay current on the latest threats, trends, and vulnerabilities.
CDR solutions are all about helping organizations to detect threats early (before they can escalate to significant incidents), minimize bad actor dwell time, and adapt more quickly to new and emerging threats. They are designed to uncover weaknesses and provide the information needed to update and improve detection rules, response protocols, and preventative security measures.
Automation is a crucial component of CDR, especially when it comes to routine tasks and initiating predefined responses when suspicious or malicious activity is detected. CDR systems often use behavioral analysis to establish a baseline of normal behavior within an organization so that any deviations from this baseline can point to potential security incidents. It’s also important that CDR solutions offer robust incident analysis and reporting and have the ability to scale to accommodate the growing needs and complexities of an organization’s infrastructure and business.
By adopting a proactive CDR approach, organizations can enhance their overall security posture and strengthen their resilience against a wide range of cyber threats.
What is the difference between EDR, XDR, and MDR?
Endpoint detection and response (EDR), extended detection and response (XDR), managed detection and response (MDR) are different approaches for detecting and responding to security incidents.
EDR solutions combine antivirus with post-detection analysis capabilities to monitor endpoint activities and identify malware infections or endpoint-specific attacks. An EDR solution is designed to provide visibility into endpoint activities, detect suspicious behavior or indicators of compromise (IoCs), and facilitate incident response at the endpoint level.
While EDR focuses on endpoint security, XDR goes a step further by integrating and correlating data from multiple security sources, including endpoints, networks, and cloud environments. It provides a more comprehensive and holistic approach to threat detection and response by offering a unified view of security incidents across an entire organization and often, leveraging automation, artificial intelligence, and advanced analytics for more efficient detection and response to complex threats.
Finally, there’s MDR, which is not just a technology, but a service provided by cybersecurity vendors. Like XDR, MDR extends beyond endpoints to cover networks, cloud environments, and other parts of an organization’s infrastructure with the goal of providing a holistic view of an organization’s security landscape.
The Netenrich MDR service, for example, provides 24/7 monitoring and response, deep expertise, comprehensive coverage, and more. Because bad actors don’t rest, neither do our security experts. Around the clock, they’ll monitor your environment for potential risks and threats so that if incidents arise, they can respond to them quickly and effectively to safeguard your assets and limit damage and exposure. As part of their response process, they investigate for root cause and lateral movement and provide incident reports that not only offer insights to any incidents but also recommendations for fortifying defenses.
Security today requires proficiency across data engineering, detection engineering, rapid response engineering, and many more cutting-edge security solutions and disciplines. At Netenrich, our seasoned professionals see what others might miss, and they know how to respond with unparalleled precision and speed.
What’s more, Netenrich’s intelligent routing capability, powered by machine learning, helps ensure that the right information gets to the right person at the right time. In relation to an incident, that right information includes context, severity, and potential impact to the business. This intelligent routing facilitates more effective resolution of critical issues with minimal disruption to operations. Learn more about intelligent routing below.
The choice between EDR, XDR, and MDR depends on an organization’s specific security needs, resources, and the complexity of its IT environment. In some cases, organizations opt for a combination of all three to achieve a comprehensive security strategy.
The role of threat intelligence in detection and response
Effective detection and response requires relevant and timely threat intelligence. This intelligence provides requisite context about potential threats and helps organizations understand the evolving tactics, techniques, and procedures (TTPs) used by adversaries. Threat intelligence can include indicators of compromise (for example, IP addresses, domain names, file hashes, and signatures associated with known malicious behavior), malware signatures, and information about software vulnerabilities, exploits, and industry-specific threats.
Knowledge Now (KNOW) is Netenrich’s proprietary threat intelligence provider. It combines machine and human insight to identify and assess risk exposure by criticality, likelihood, and impact of an exploit and help organizations make real-time informed decisions when responding to potential threats.
Routine task automation and response orchestration
Again, automation of routine tasks is crucial for streamlining processes, including the coordination of actions taken in response to security incidents or IT operations events (aka response orchestration).
Resolution Intelligence Cloud helps organizations reduce manual effort by creating and automating response workflows based on specific triggers, such as security alerts. The platform quickly assesses the severity and business impact of an incident, prioritizes response, and helps IT and security teams determine the appropriate course of action. In some cases, the platform can automate remediation actions, including isolating affected endpoints, blocking malicious IP addresses, and taking other predefined steps to neutralize threats.
Response orchestration often involves collaboration among security teams and other stakeholders. Netenrich facilitates coordination during incident response by enabling complete visibility that ensures all parties are working from the same information. As mentioned above, the platform also incorporates threat intelligence to enhance the context and accuracy of response actions.
Intelligent routing and collaboration
Intelligent routing (also known as impact-based routing) is the use of advanced algorithms and technologies to efficiently direct and manage alerts and notifications. The goal is to get the right information in the hands of the right people so they can take appropriate and timely action to maintain business continuity and mitigate potential damage. Intelligent routing requires complex data analysis along with a deep understanding of what’s important to different industry sectors and what assets are most critical to the business — because ultimately, the impact of a threat highly depends on the targeted asset.
For example, if a targeted server holds a company’s secret sauce, a compromise could be very impactful. If, however, the server stores an organization’s cafeteria menu, maybe less so. Organizations can build that kind of business-impact information into the Resolution Intelligence Cloud platform so that when their teams get an alert, they know whether it’s mission-critical and something they need to act on immediately versus something less urgent. This intelligence also feeds into the adaptability of the system in general as an organization continually assesses and reassesses what’s most important to its business.
The Netenrich platform analyzes vast volumes of data from across data centers, third-party systems, the cloud and then routes pertinent situational intelligence (based on a likelihood, impact, and confidence score) to the correct group or individual. This way, when an alert is routed, the recipient has a clear picture (ActOn) of what’s affected, what the impact is, what the risks are, and what the associated threat intelligence is. Because this actionable intelligence is also tied into a collaborative workbench, users can easily bring in other relevant people as needed — for example, representatives across SecOps, Digital Ops, and DevOps — to decide on a prompt course of action.
Self-sufficient and self-healing systems
Self-healing systems allow an IT environment or security infrastructure to automatically detect, respond to, and recover from security incidents without the need for manual intervention. These systems leverage automation and orchestration to enhance an organization’s resilience against cyber threats.
At Netenrich, we don’t design systems to assign operational tasks. We design systems to be self-sufficient and self-healing to reduce human involvement while speeding detection and response to minimize potential damage. We also understand that everything in security is based on a point in time and that the way a business secures itself one day may need to change the next. Thus, from every lesson learned, we tune our systems and make changes to improve processes — and the same goes for every organization we work with.
