CERT, CSIRT, CIRT and SOC are terms you'll hear in the realm of incident response. In a nutshell, the first three are often used synonymously to describe teams focused on incident response, while the last typically has a broader cybersecurity and security scope.
Still, terminology can be important. Inconsistent terminology can cause misunderstandings of what is meant and can confuse your team's incident response effort planning by complicating the understanding of accepted practices.
To that end, here's a deeper look at the terms.
CERT vs. CSIRT vs. CIRT
Let's first look at the terms that describe common organizational models of incident response teams. But take these definition with a grain of salt -- just because two organizations both call their response team a CSIRT, for example, doesn't mean those two teams have the same goals or methods, or conform to an idealized definition.
CSIRT stands for computer security incident response team. CERT stands for computer emergency response (or readiness) team. And CIRT can stand for either computer incident response team or, less frequently, cybersecurity incident response team. CSIRT, CERT and CIRT are often used interchangeably in the field. In fact, CSIRT and CIRT are almost always near-equivalent; essentially they are synonymous. An organization might prefer one or the other based on the organization's language or style, or subtle differences in organizational scope. Generally though, the meaning is consistent with the formal definition and description of CSIRTs outlined in the 2007 Carnegie Mellon document "Defining Computer Security Incident Response Teams." Its first line reads: "A computer security incident response team (CSIRT) is a concrete organizational entity (i.e., one or more staff) that is assigned the responsibility for coordinating and supporting the response to a computer security event or incident."

What is CERT?
As for the term CERT, although many companies use the term generically, it has been a registered mark of Carnegie Mellon University since 1997. Companies can apply for authorization to use the CERT mark. Companies that have not done should not use that term for a consulting service name or managed security service provider, or they might be infringing on that. Therefore, if your organization does use the term CERT as part of a response team name, it's useful to have a candid conversation with legal or internal counsel about that usage.
Just because two organizations both call their response team the CSIRT, for example, doesn't mean those two teams have the same goals or methods, or conform to an idealized definition.
Part of the challenge with organizations using the name CERT internally is that it can be confusing. Is CERT intended as a synonym for CSIRT or is the organization trying to convey something else? Both can be true depending on context.
Carnegie Mellon's CERT designation has a particular focus and niche it occupies; it operates as a "…partner with government, industry, law enforcement, and academia to improve the security and resilience of computer systems and networks…" A CERT studies "…problems that have widespread cybersecurity implications and develop[s] advanced methods and tools."
Some organizations reflect this in the way they use the term. In other words, they use CERT to reflect that their internal team's focus is subtly different from that of a typical CSIRT. For example, maybe the team places additional emphasis on partnership with other internal or external teams and organizations, has more focus on methodology and tool development (e.g., those designed to forecast issues before they arise), or focuses more on emerging threat research (e.g., adversary methodology or tradecraft). The term CERT used in this way focuses more broadly on improving incident response as a discipline than on just its own organization.
Still other organizations that use CERT -- generally those unaware of CERT's status as a registered service mark -- use the term as a synonym for CIRT or CSIRT.
What are the differences between CERT, CSIRT and CIRT?
Practitioners should understand the fluidity with which teams use these terms. CERT, CSIRT and CIRT groups can exist as a permanently staffed group or can be pulled together on an ad hoc basis in response to an event. Either way, their focus is almost always the four phases of incident response outlined in the NIST "Computer Security Incident Handling Guide":
preparation
detection and analysis
containment, eradication and recovery
post-incident activity
These phases concentrate on the detection and remediation of security incidents. They also include the governance structures an organization uses to prepare for security incidents and the post-incident activities designed to streamline future efforts.
There is nuance here, though. Not every group at every company does the same thing. Some teams might use a term like CSIRT in a way that aligns with NIST's guidance, but put their own spin on what they do. For example, one organization might see the role of their CSIRT as focused more on policy while another might be more focused on operational issues like looking through log files and tracking activity on the network.
A SOC is broader in scope
A security operations center (SOC) is another term you'll hear in the context of incident response teams. However, a SOC generally encompasses multiple aspects of security operations, while CSIRTs, CERTs and CIRTS focus specifically on incident response.
A SOC's purview can include the incident response function (either in whole or in part) as well as other tasks. For example, a SOC can:
encompass monitoring operations and controls (such as an intrusion detection, system/intrusion prevention system, security information event management/security information management);
oversee evaluation of operational and security telemetry and information gathering; and,
manage tasks such as identity management and authorization, firewall and filtering ruleset maintenance (both review and change management), forensics and investigation support, or any other aspect of operational security.
A SOC's monitoring efforts is likely to extend beyond incident response. A SOC might harvest and collect metrics to support customer service or service delivery (at a managed security service provider, for example) or it might support management reporting like preparation of metrics and data to support risk assessment or for audit support. While a SOC often comes up in the context of incident response, it almost always has other elements of security within its scope of responsibility. A SOC is likely to have a broader operational purpose and scope than a CSIRT or CIRT. If there is a SOC in a given organization, incident response likely falls within the purview of the SOC as an operational security function. Again, the specifics depend on the organization.
Should you implement a CERT/CSIRT/CIRT or SOC?
With a clear understanding of these terms, organizations can identify which type of incident response team is right for them and how to build the security team of choice. The choice should be based on your organization's goals, structure and use of resources. For example, if the need for monitoring is paramount and your organizational structural is conducive to allowing centralization of that in one physical or logical location, there may be advantages to creating a SOC (for example, economies of scale or a simplified reporting hierarchy). By contrast, if your organizational structure is more decentralized, or otherwise not conducive to centralization of monitoring and other security operations, a CSIRT may make more sense.
It's important to evaluate the relative advantages of both, understand your organization's needs, and select the approach that's optimal for your enterprise.
The CSIRT is an objective body with the required technical and procedural skills and resources to appropriately handle computer security incidents. The CSIRT is responsible for identifying and controlling the incidents, notifying designated CSIRT responders, and reporting findings to management.
There are three main types of incident response teams—Computer Security Incident Response Team (CSIRT), Computer Emergency Response Team (CERT), and Security Operations Center (SOC).
However, a SOC generally encompasses multiple aspects of security operations, while CSIRTs, CERTs and CIRTS focus specifically on incident response. A SOC's purview can include the incident response function (either in whole or in part) as well as other tasks.
Indian - Computer Emergency Response Team. CERT-In is operational since January 2004. The constituency of CERT-In is the Indian Cyber Community. CERT-In is the national nodal agency for responding to computer security incidents as and when they occur.
3 Types Of Incidents That Stand Out: Is Your Help Desk Prepared?
Major Incidents. Large-scale incidents may not come up too often, but when they do hit, organizations need to be prepared to deal with them quickly and efficiently. ...
What are Priority 2 incidents? SIRS Priority 2 incidents include any reportable incident that does not meet the Priority 1 criteria i.e. where a consumer is momentarily shaken or upset, or experiences temporary redness or marks that do not bruise and where medical or psychological treatment is not required.
Executive Sponsor. The first step in building a CSIRT is finding an executive sponsor. This person is one of the executives or a board member — often the CISO or CSO. They will act as the team leader, oversee CSIRT activities and ensure the team has the resources and budget needed to operate effectively.
NIST's publication 800-64 proposes that CSIRTs should be composed of a manager, a technical lead and team members. The PCI DSS makes it mandatory to assign an individual or a team to various tasks, including establishing, documenting and distributing security incident response and escalading procedures when necessary.
Although a SIEM is not a requirement to have a SOC, the two cybersecurity strategies work together to protect internal resources. Without a SIEM, a SOC team does not have the right tools to detect and contain threats.
Companies are increasingly hiring cybersecurity job applicants who do not have college degrees but do have relevant certificates. The field is growing so fast that there simply aren't enough degree-holding candidates to fill the positions, so those who have the right certificates have a great chance of getting hired.
The Community Emergency Response Team (CERT) program educates volunteers about disaster preparedness for the hazards that may occur where they live. CERT trains volunteers in basic disaster response skills, such as: Fire safety. Light search and rescue.
The Community Emergency Response Team (CERT) Program educates people about disaster preparedness for hazards that may impact their area and trains them in basic disaster response skills, such as fire safety, light search and rescue, team organization, and disaster medical operations.
While learning how to work within the SOC and properly detect an attack or breach are valuable skills for those looking to start or advance their cybersecurity career, these analysts work long hours, are under constant stress and are prone to burnout.
SOC teams are responsible for identifying, deploying, configuring, and managing their security infrastructure. Addressing Support Tickets: Many SOC teams are part of the IT department. This means that SOC analysts may be called upon to address support tickets from an organizations' employees.
The three most general categories are natural threats (such as earthquakes), physical security threats (such as power outages damaging equipment), and human threats (blackhat attackers who can be internal or external.)
Lack of executive commitment, process breakdowns, ineffective workforces (often a result from poor management and lack of commitment … again) and talent shortages have killed more SOCs than any and all technology failures.
ICS divides an emergency response into five manageable functions essential for emergency response operations: Command, Operations, Planning, Logistics, and Finance and Administration. The basic structure of ICS is the same regardless of the type of emergency.
They include Who, What, When Where, and Why. The 5 Ws are often mentioned in journalism (cf. news style), research, and police investigations. They constitute a formula for getting the complete story on a subject.
Training your brain before you find yourself in a high-pressure situation may help you save a life or potentially help someone in pain. There are three basic C's to remember—check, call, and care.
The most common work injuries are slips, trips, and falls, overexertion, and contact with equipment. All of these injuries are mostly preventable by taking the proper precautions and adhering to OSHA's guidelines.
A priority 1 reportable incident is a reportable incident: that causes, or could reasonably have caused, a resident physical or psychological injury or discomfort that requires medical or psychological treatment to resolve; or. where there are reasonable grounds to report the incident to police; or.
Depending on the impact and urgency, a major incident will be categorized as a P1 or P2. Incident Coordinators utilize a priority matrix to determine the appropriate impact and urgency. All P1 tickets are considered major incidents.P2 tickets are considered major if the impact is “multiple groups” or “campus.”
This type of incident is the most complex, requiring national resources for safe and effective management and operation. All command and general staff positions are filled. Operations personnel often exceed 500 per operational period and total personnel will usually exceed 1,000.
The Computer Security Incident Response Team (CSIRT) Services Framework is a high-level document describing in a structured way a collection of cyber security services and associated functions that Computer Security Incident Response Teams and other teams providing incident management related services may provide.
As a result, the list of the responsibilities of CSIRT includes: Remediating security incidents. Detecting and taking immediate action upon incidents. ... An incident response team consists on three distinct components:
2. Definition(s): A capability set up for the purpose of assisting in responding to computer security-related incidents; also called a Computer Incident Response Team (CIRT) or a CIRC (Computer Incident Response Center, Computer Incident Response Capability). Source(s): NIST SP 800-61 Rev.
The CSIRT should include a cross section of business and technical experts with the authority to take action in support of the business. Members should include representatives from management, technical, legal, and communications disciplines, as well as security committee liaisons.
An incident response playbook empowers teams with standard procedures and steps for responding and resolving incidents in real time. Playbooks can also include peacetime training and exercises, which will prepare the team for the next incident.
The goal of a CSIRT is to minimize and control the damage resulting from incidents, provide effective guidance for response and recovery activities, and work to prevent future incidents from happening.
The NIST incident response lifecycle breaks incident response down into four main phases: Preparation; Detection and Analysis; Containment, Eradication, and Recovery; and Post-Event Activity.
