Title: Establishing a Security Incident Response Team (SIRT) for a Large Enterprise
Introduction
In today's digital landscape, cybersecurity threats are constantly evolving, and large
enterprises are increasingly vulnerable to various cyberattacks. To effectively respond to
and mitigate these threats, it is essential for organizations to establish a dedicated
Security Incident Response Team (SIRT). This paper outlines a proposed structure for a
SIRT within a large enterprise, highlighting the importance of designated roles and
responsibilities, including incident handlers, investigators, and communication liaisons.
Security Incident Response Team Structure
To build an effective SIRT for a large enterprise, it is crucial to establish a well-defined
structure with clear roles and responsibilities. The proposed structure consists of the
following key roles:
a. Incident Handlers:
Incident handlers are the first responders to cybersecurity incidents. They play a crucial
role in detecting, analyzing, and containing security breaches.
Responsibilities of incident handlers include:
Monitoring network and system logs for suspicious activities.
Identifying and classifying incidents based on severity.
Initiating immediate containment measures to limit the impact of the incident.
Collecting and preserving digital evidence for further investigation.
Incident handlers serve as the frontline responders to cybersecurity incidents, acting
swiftly to mitigate damage and contain threats. They are the first line of defense.
These professionals continuously monitor network and system logs using intrusion
detection systems (IDS) and security information and event management (SIEM) tools.
Their expertise lies in recognizing anomalous or suspicious activities and identifying
potential incidents.
Incident handlers are tasked with classifying incidents based on their severity and
potential impact, which helps prioritize response efforts.
Rapid containment is a top priority for incident handlers. They initiate immediate actions
to stop the spread of the incident, such as isolating affected systems, blocking malicious
network traffic, or disabling compromised accounts.
Incident handlers also play a role in documenting their actions and the incident's timeline,
which aids in post-incident analysis and reporting.

which aids in post-incident analysis and reporting.
b. Investigators:
Investigators are responsible for conducting in-depth analysis of security incidents to
determine the root cause, extent of damage, and potential vulnerabilities.
Responsibilities of investigators include:
Performing forensic analysis of compromised systems.
Tracking the attacker's tactics, techniques, and procedures (TTPs).
Identifying vulnerabilities and weaknesses that led to the incident.
Collaborating with external entities, such as law enforcement or third-party experts, when
necessary.
Investigators are responsible for conducting in-depth analysis once an incident has been
contained. Their primary objective is to determine the root cause of the incident and
gather evidence for potential legal or disciplinary actions.
These experts employ digital forensics techniques to examine compromised systems,
malware, and other artifacts left behind by attackers.
Investigators track and document the attacker's tactics, techniques, and procedures
(TTPs), which helps in building a profile of the threat actor and enhances the
organization's threat intelligence.
Identifying vulnerabilities and weaknesses within the organization's security posture is
another key role of investigators. This information is used to strengthen defenses and
prevent future incidents.
In some cases, investigators may need to collaborate with external entities, such as law
enforcement agencies or third-party cybersecurity experts, to aid in the investigation,
especially in the case of significant cyberattacks.

especially in the case of significant cyberattacks.
c. Communication Liaisons:
Communication liaisons act as the bridge between the SIRT and the rest of the
organization, as well as external stakeholders.
Responsibilities of communication liaisons include:
Notifying relevant internal teams, such as legal, PR, and senior management, about the
incident.
Coordinating external communications with customers, partners, regulators, and law
enforcement agencies.
Providing regular updates to stakeholders to maintain transparency and manage the
organization's reputation.
Communication liaisons serve as the primary point of contact between the SIRT and
various internal and external stakeholders.
They are responsible for notifying and updating relevant internal teams, including legal,
public relations, senior management, and other departments impacted by the incident.
External communication is a crucial aspect of their role, as they liaise with customers,
partners, regulatory authorities, and law enforcement agencies as necessary.
Communication liaisons provide regular and accurate updates to stakeholders, ensuring
transparency and maintaining the organization's reputation during and after the incident.
In crisis situations, these professionals play a vital role in managing public relations to
minimize damage to the organization's brand and credibility.

Building a skilled and knowledgeable SIRT is essential. Regular training and skill
development programs should be put in place to ensure that team members stay updated
on the latest cybersecurity threats and incident response techniques.
Incident handlers benefit from training in threat detection and real-time monitoring tools,
while investigators require expertise in digital forensics and malware analysis.
Communication liaisons should have effective communication and crisis management
training to handle external interactions professionally.
Incident Response Playbooks:
Developing incident response playbooks or procedures for different types of incidents
can streamline the response process. Playbooks provide step-by-step guidance for
incident handlers and investigators.
These documents define roles, responsibilities, and actions to be taken during incidents,
reducing confusion and ensuring consistency in response efforts.
Technology and Tools:
SIRT members must have access to appropriate cybersecurity tools and technologies to
support their tasks effectively.
Incident handlers rely on tools like SIEM systems, intrusion detection systems, and
endpoint detection and response (EDR) solutions.
Investigators need access to digital forensics tools and threat intelligence platforms to
analyze incident data thoroughly.
Legal and Compliance Considerations:
Compliance with legal and regulatory requirements is crucial. SIRT members should be
aware of data protection laws, breach notification requirements, and other relevant legal
aspects.
Investigators must handle digital evidence carefully to ensure its admissibility in potential
legal proceedings.
Continuous Improvement:
Establish a culture of continuous improvement within the SIRT. After each incident,
conduct post-incident reviews (PIRs) to evaluate the team's performance and identify
areas for enhancement.
Use lessons learned from PIRs to update incident response playbooks, refine processes,
and enhance the team's overall capabilities.
Cross-Functional Collaboration:
Foster collaboration between the SIRT and other departments within the organization.
This includes IT, legal, HR, and business units.
IT teams can provide technical support during incident containment, legal teams can
address compliance and regulatory issues, and HR can assist with employee-related
incidents.
Incident Metrics and Reporting:
Define key performance indicators (KPIs) and metrics to measure the effectiveness of the
SIRT's response efforts.
Regularly report incident statistics and trends to senior management to demonstrate the
team's value and the organization's security posture.

Leverage advanced analytics and machine learning algorithms to detect anomalous
behavior and patterns that may indicate a security incident.
Machine learning can be used for predictive analysis to identify potential future threats
based on historical data.
Threat Hunting:
Introduce a threat hunting program within the SIRT. Threat hunters proactively search for
signs of hidden threats that may not trigger traditional security alerts.
This approach can uncover sophisticated threats that may have evaded initial detection.
Incident Simulation and Red Teaming:
Regularly engage in red teaming exercises where external security experts simulate
attacks on your organization. This helps identify weaknesses in your security posture.
Simulated attacks can provide valuable insights and prepare the SIRT for real-world
incidents.

cybersecurity. Certain events or developments can trigger cyberattacks or influence threat
actor behavior.
Threat Sharing and Collaboration:
Actively participate in threat information sharing and collaborative security communities.
Sharing threat intelligence with peers can provide early warnings of potential threats.
Cultural and Organizational Awareness:
Foster a cybersecurity-aware culture within the organization. Employees at all levels
should understand their role in incident reporting and prevention.
Encourage reporting of security incidents promptly to the SIRT, even if they appear
minor.
2. Incident Classification and Prioritization: Recommend a framework for classifying
and prioritizing incidents based on severity and impact. Discuss the criteria for
distinguishing between different incident types and the urgency of response.
Establishing a clear and effective framework for classifying and prioritizing security
incidents is crucial for a Security Incident Response Team (SIRT) in a large enterprise.
Such a framework helps in allocating resources efficiently and responding promptly to
the most critical threats. Below is a recommended framework that considers both severity
and impact:
Incident Classification Criteria:
Severity Levels:
Low Severity: Incidents with minimal impact and low potential for harm. They may have
a limited scope and can often be handled by standard procedures.
Medium Severity: Incidents that have moderate impact potential and may require more
investigation and resources to resolve.
High Severity: Incidents with a significant impact potential, posing a substantial threat to
the organization's data, systems, or reputation.
Incident Types:
Malware: Incidents involving the presence or suspected presence of malware, such as
viruses, ransomware, or Trojans.
Unauthorized Access: Incidents related to unauthorized access attempts, including brute
force attacks, credential theft, or unauthorized system access.
Data Breaches: Incidents where sensitive data is accessed, stolen, or exposed, potentially
leading to compliance violations and reputational damage.
Denial of Service (DoS) or Distributed Denial of Service (DDoS): Incidents involving
attacks that disrupt or degrade network or service availability.
Insider Threats: Incidents related to employees or internal actors engaging in malicious
activities or accidental data exposures.
Phishing and Social Engineering: Incidents involving deceptive tactics to trick
individuals into divulging sensitive information or performing harmful actions.
Vulnerability Exploitation: Incidents where known vulnerabilities are exploited to gain
unauthorized access or compromise systems.
Advanced Persistent Threats (APTs): Incidents involving sophisticated and targeted
attacks, often associated with nation-state actors or well-funded threat groups.
Incident Prioritization Criteria:
Impact on Business Operations:
Consider how the incident impacts critical business functions. High-impact incidents
affecting core operations should be prioritized over those with minimal operational
impact.
Data Sensitivity:
Assess the sensitivity of the data involved. Breaches or incidents involving highly
sensitive information, such as financial or customer data, may warrant higher priority.
Regulatory and Legal Requirements:
Evaluate incidents in the context of legal and regulatory obligations. Incidents that may
result in compliance violations or legal consequences should receive immediate attention.
Reputational Damage:
Assess the potential harm to the organization's reputation. Incidents that could lead to
significant reputational damage should be addressed urgently.
Duration and Persistence:
Consider how long the incident has persisted or how quickly it is spreading. Rapidly
evolving incidents or those with a long history may require immediate response.
Scope and Extent:
Evaluate the scope of the incident. Incidents affecting a wide range of systems or a large
number of users should be prioritized.
Threat Actor Attribution:
If possible, determine the identity or affiliation of the threat actor. Incidents involving
sophisticated actors or nation-state entities may require special attention.
Business Continuity Impact:
Assess the potential impact on business continuity. Incidents that threaten the
organization's ability to function should be addressed urgently.
Incident Classification Factors:
Attack Vector and Complexity:
Assess the attack vector used by the threat actor. Incidents involving sophisticated attack
techniques or novel methods may require higher priority.
Consider the complexity of the incident. Complex incidents may take longer to
investigate and mitigate.
Resource Availability:
Take into account the availability of internal and external resources for incident response.
If resources are limited, prioritize incidents based on resource constraints.
External Impact:
Evaluate incidents with external consequences. Incidents that impact customers, partners,
or other external stakeholders may need swift resolution to maintain trust.
False Positives and Noise:
Distinguish between true incidents and false positives or noise generated by security
monitoring systems. Prioritize verified incidents over false alarms.
Incident Prioritization Factors:
Incident Escalation:
Implement an escalation process within the SIRT. High-severity incidents should have a
predefined escalation path to ensure senior management and decision-makers are
informed promptly.
Business Impact Assessment:
Perform a comprehensive business impact assessment to quantify the potential financial
and operational consequences of an incident. This assessment can guide prioritization.
Response Time Objectives (RTO):
Set response time objectives for different incident categories. For example, establish
shorter response times for high-severity incidents and longer windows for lower-severity
ones.
Public Relations and Communication Considerations:
Consider the need for immediate communication with customers, shareholders, and the
public in high-impact incidents. Public relations and communication strategies can
impact incident prioritization.
Industry and Sector Relevance:
Assess the relevance of an incident to your specific industry or sector. Some industries
may be more targeted by certain threat actors, and incidents in these sectors may require
heightened attention.
Historical Data and Incident Trends:

resemble past, impactful events should be addressed with increased priority.
Legal and Regulatory Reporting Deadlines:
Be aware of any legal or regulatory reporting deadlines for security incidents. Failure to
meet these deadlines can result in penalties or legal consequences.
Incident Containment and Eradication Complexity:
Consider the technical complexity of containing and eradicating the incident. More
complex incidents may require higher prioritization due to the increased effort needed for
resolution.
External Threat Landscape:
Stay informed about the broader threat landscape. If there is a surge in a specific type of
attack (e.g., ransomware attacks), prioritize incidents related to that threat accordingly.
Incident Classification and Prioritization Metrics:
Impact Metrics:
Develop quantitative metrics to measure the impact of security incidents. This could
include financial losses, system downtime, data volume affected, or the number of
systems compromised.
Assign numerical values to these metrics to enable a data-driven approach to
prioritization.
Cyber Risk Assessment:
Integrate a cyber risk assessment framework into the incident prioritization process. This
assessment considers not only the severity and impact of incidents but also the
organization's overall risk posture.
