What is threat detection and response (TDR)?

Explore Malwarebytes Business Solution



Simply put, what is threat detection?

Threat detection is the process of monitoring, identifying, and providing alerts on malicious cyberthreat activity network wide. The pinnacle of cybersecurity maturity involves threat detection which accelerates the investigation process in an effort to prioritize and mitigate threats before vulnerabilities are exploited. Once a threat has been detected, security teams must rapidly respond to intrusions and limit cyber risk threatening an organization’s security ecosystem.

What is threat detection and response?

Supporting security prevention and detection, threat detection and response (TDR) dually focuses on detecting threats, investigating them, and responding to incidents with accuracy and speed. The sooner threat detection tools uncover intrusions, the more readily IT security teams, SOC analysts, and incident response staff respond to breaches and mitigate damage to organizations.

Cybercriminals carry out data breaches to target businesses and sensitive data with the intent to cause reputational and financial harm. In addition to today's threat detection tools, recognizing and detecting indicators of compromise (IOC) can help security teams move in quickly to contain and neutralize threats.

Cyber threat detection and response solutions use various methods to help:

The MITRE ATT&CK Framework

The MITRE ATT&CK framework is a world-wide accessible resource based on real-life adversary attacks which tracks behavior, tactics, and techniques in cyberattacks. Organizations, threat hunters, SOC analysts, MDR security teams and EDR experts use the MITRE ATT&CK matrices and the framework to improve their security posture.

The MITRE ATT&CK Evaluation or MITRE ENGENUITY ATT&CK, is the industry standard for testing, analyzing, and evaluating endpoint detection and response (EDR) tools against simulated, known adversary cyberattacks.

Threat hunting, investigation, and threat analysis

Threat detection and response remains the cornerstone of managed detection and response (MDR)  and endpoint detection and response (EDR). Both EDR and MDR security rely on threat detection technology to carry out threat hunting, monitoring and analysis of threats, eliminating false positives, and responding to incidents.

Threat intelligence

Technologies such as security information and event management (SIEM) and security orchestration automation and response (SOAR), are both threat intelligence tools that help security teams handle alert fatigue and high volumes of data to accelerate the threat detection process.

Challenges with detection in cloud environments

Detecting malicious threats in a complex cloud environment presents many unique challenges. Due to the multifaceted nature of attack surfaces within the cloud, businesses and security teams struggle to achieve full visibility and monitoring over cloud assets, applications, and storage. Many of these landscapes are shared with and between third parties which makes cloud file sharing vulnerable to cyber exploitation.
