Event Triage
The process of quickly assessing and prioritizing security events to determine their potential impact and the appropriate response. This involves reviewing alerts and notifications generated by security monitoring systems, such as intrusion detection systems (IDS) and security information and event management (SIEM) solutions, to identify events that require further investigation or action. During event triage, security analysts review the available information to determine the scope and severity of the security event, including the type of attack, the affected systems and data, and the potential impact on the organization. Based on this assessment, they prioritize the event and determine the appropriate response, which may include further investigation, containment and remediation, or escalation to incident response teams. The goal of event triage is to quickly identify and respond to security events to minimize the impact on the organization and prevent further damage. Effective event triage requires a combination of automated security monitoring tools, skilled security analysts, and well-defined processes and procedures.
Exposure Resolution
The process of identifying and addressing security vulnerabilities and weaknesses that could potentially expose an organization's assets, such as data, systems, and networks, to risk. Exposure resolution involves a comprehensive assessment of an organization's security posture, including the identification of potential attack vectors and vulnerabilities, the prioritization of risks based on their severity and impact, and the implementation of appropriate controls and countermeasures to mitigate the identified risks. The goal of exposure resolution is to reduce the likelihood and impact of security breaches and to improve the overall resilience of the organization's security posture. Effective exposure resolution requires a proactive and continuous approach to security risk management, with a focus on identifying and addressing vulnerabilities before they can be exploited by attackers.
Malware Containment
The process of isolating and controlling the spread of malicious software (malware) within a system or network. Malware containment is typically used in response to a security incident, such as a virus outbreak or a targeted cyber attack, to prevent the malware from causing further damage or spreading to other systems or networks. The process of malware containment involves identifying the affected systems and quarantining or disconnecting them from the network to prevent the malware from communicating with its command-and-control servers or spreading to other systems. Malware containment may also involve the use of anti-malware software to detect and remove the malware from affected systems. The goal of malware containment is to limit the impact of the security incident and to prevent further damage or data loss, while minimizing the disruption to normal business operations. Effective malware containment requires a coordinated effort from multiple teams, including IT, security, and management, and may involve the implementation of incident response plans and procedures.
Platform Optimization
The process of improving the performance and efficiency of security platforms, such as firewalls, intrusion detection and prevention systems, and security information and event management (SIEM) solutions. This involves a range of activities, such as adjusting settings, optimizing rules and filters, configuring log management, and reducing the impact of false positives. Platform optimization aims to maximize the effectiveness of the security platform in detecting and responding to security threats, while minimizing the workload on security analysts and the impact on system performance. Effective platform optimization requires a deep understanding of the security risks and threats facing the organization, as well as the capabilities and limitations of the security platform being used. It also involves ongoing monitoring and analysis of security events and performance metrics, with the goal of identifying opportunities for further optimization and improvement.
Platform Tuning
The process of configuring and optimizing security platforms, such as intrusion detection systems (IDS), intrusion prevention systems (IPS), and security information and event management (SIEM) solutions, to improve their effectiveness and reduce false positives. This involves adjusting the settings and rules within the platform to better align with the specific security requirements of the organization. Platform tuning can include a range of activities, such as adjusting thresholds, fine-tuning rules and filters, creating custom signatures, and defining correlation rules. The goal of platform tuning is to improve the accuracy of the security platform in detecting and responding to security events, while minimizing the number of false positives that may trigger unnecessary alerts or actions. Effective platform tuning requires a deep understanding of the security risks and threats facing the organization, as well as the capabilities and limitations of the security platform being used.

Root Cause Analysis
The process of identifying the underlying cause of a security incident or breach. This involves investigating the incident in detail, analyzing the data and logs, and identifying the series of events that led to the breach. The purpose of root cause analysis is to identify the underlying factors that allowed the breach to occur, such as a vulnerability in a system or application, a misconfiguration, or human error. By identifying the root cause, organizations can take steps to address the underlying issue and prevent similar incidents from occurring in the future. Root cause analysis is an important part of the incident response process, and is often used to improve an organization's security posture and reduce the risk of future security incidents.
Threat Containment
The process of limiting the damage caused by a security breach or cyber attack. It involves identifying and isolating the affected systems, applications, or data to prevent the threat from spreading to other parts of the network or system. Threat containment may also involve taking steps to mitigate the attack's impact and prevent further damage, such as shutting down infected systems, blocking network access, or removing malicious code. The goal of threat containment is to minimize the impact of the attack and prevent it from causing further harm, while also preserving evidence that can be used to identify the source of the attack and prevent future incidents.
Threat Hunting
The proactive process of searching for and identifying potential security threats within an organization's network or systems. This involves using various tools and techniques to detect suspicious activity, investigate it further, and ultimately identify and eliminate any potential threats before they can cause harm. Threat hunting typically involves analyzing large amounts of data and using advanced analytics to identify patterns and anomalies that may indicate the presence of a threat. Threat hunting aims to stay one step ahead of potential attackers and proactively defend against cyber threats before they can cause damage.
Threat Remediation
The process of addressing and correcting the root cause of a security threat or incident. This involves taking steps to remediate any vulnerabilities or weaknesses that allowed the threat to occur and implementing new security controls to prevent similar incidents from occurring in the future. Remediation may involve a variety of activities, such as patching vulnerabilities, reconfiguring systems, implementing new security policies or procedures, and providing training and awareness programs for employees. The goal of threat remediation is to address the underlying causes of the security incident, rather than just addressing the symptoms, and to improve the organization's overall security posture. Effective threat remediation requires a thorough understanding of the nature of the threat and the factors that allowed it to occur, as well as a coordinated effort from multiple teams across the organization, including IT, security, and management.
Threat Resolution
The process of responding to and eliminating a security threat or incident.
