Frequently asked questions

What is cyber security incident response?

Cyber security incident response is a structured approach to addressing and managing the aftermath of a security breach or cyberattack. The goal is to handle the situation in a way that limits damage and reduces recovery time and costs. This process involves a sequence of actions, starting from the initial identification of the incident, followed by a comprehensive response that includes containment, eradication, and recovery.

The incident response is not just about reacting to an attack; it's about having a proactive plan in place. This includes preparing for potential threats, detecting and analysing any incidents, and then swiftly responding to and recovering from these events. The effectiveness of an incident response can significantly impact the severity of the breach and the organisation’s ability to quickly resume normal operations. It is an integral part of an organisation's cybersecurity strategy, ensuring that they are prepared to face any cyber threats effectively.

What does a cyber incident responder do?

A cyber incident responder is responsible for managing the immediate response to a cybersecurity incident. Their role includes identifying, investigating, and responding to cyber threats, as well as mitigating any damage caused by such events. Initially, they work to contain the threat to prevent further damage, followed by a detailed analysis to understand the nature and scope of the attack.

Cyber incident responders also play a critical role in recovery efforts, working to restore systems and data affected by the incident. Beyond these immediate tasks, they often engage in post-incident activities, such as conducting a thorough review of the event to identify lessons learned and improve future response efforts. This role requires a blend of technical expertise, problem-solving skills, and the ability to remain calm under pressure, making it crucial in safeguarding an organisation's digital assets.

What are the 7 steps in incident response?

The seven steps in incident response provide a comprehensive framework for managing and resolving cyber incidents. These steps are:
1. Preparation: Establishing policies, procedures, and tools to handle potential incidents.
2. Identification: Detecting and determining the nature of the cyber threat.
3. Containment: Isolating affected systems to prevent the spread of the threat.
4. Eradication: Eliminating the threat from the organisation’s environment.
5. Recovery: Restoring and returning affected systems to their normal state.
6. Lessons Learned: Reviewing the incident to understand what happened and why.
7. Post-Incident Handling: Implementing improvements based on the lessons learned to strengthen security postures and response capabilities for future incidents.

Following these steps ensures a methodical and effective approach to incident management, minimising the impact of the threat and safeguarding against future vulnerabilities.

What is the difference between a SOC and a CSIRT?

A Security Operations Centre (SOC) and a Cyber Security Incident Response Team (CSIRT) are both crucial elements in an organisation's cybersecurity framework, but they have distinct roles. The SOC is a centralised unit that continuously monitors and analyses an organisation's security posture. It focuses on the detection, analysis, and response to cyber incidents using a combination of technology solutions and processes.

On the other hand, a CSIRT specifically focuses on responding to cybersecurity incidents. While a SOC provides 24/7 monitoring and initial incident detection, a CSIRT is typically activated in response to an incident to handle the containment, eradication, and recovery phases. The CSIRT often works closely with the SOC, but its primary role is to manage and coordinate the response to the incident. Together, the SOC and CSIRT provide a comprehensive approach to managing and mitigating cyber threats.

How do you prioritise incidents in cyber incident response?

In cyber incident response, prioritising incidents is a critical step to ensure an effective response. We prioritise based on factors like the severity of the threat, the potential impact on the organisation, the sensitivity of compromised data, and the likelihood of spread or escalation. High-priority incidents might include active attacks that threaten critical infrastructure or involve sensitive data breaches.

We use a combination of automated tools and expert analysis to quickly assess the severity of each incident. This assessment helps in allocating resources and determining the urgency of the response. Prioritisation is an ongoing process throughout the incident lifecycle, as new information can change the severity or scope of an incident.

How does your incident response team manage to act so quickly in the event of a cyberattack?

Our Incident Response team's ability to act swiftly in the face of a cyberattack is rooted in our comprehensive preparedness and sophisticated monitoring systems. Operating 24/7, the team is always on high alert, with protocols in place to immediately identify and assess any threat.

This quick action minimises damage and accelerates the recovery process, aiming to get your systems operational with minimal downtime. Our structured and agile response process ensures precision and speed, focusing on preventing further harm and facilitating a smooth path to recovery.

How does conducting a Root Cause Analysis (RCA) strengthen my organisation’s cybersecurity posture?

Conducting a Root Cause Analysis (RCA) following a cyberattack is crucial for not just understanding the attack but fortifying your defences against future threats. Our RCA team delves into the intricacies of the attack using forensic techniques to dissect its origins, pathways, and exploited vulnerabilities. By leveraging state-of-the-art tools and our vast expertise, we can identify precisely how the breach occurred.

This thorough investigation allows us to pinpoint and address the underlying weaknesses in your cybersecurity posture. The RCA report we provide goes beyond a simple analysis; it offers actionable recommendations designed to strengthen your defences, thereby significantly enhancing your organisation's resilience against potential future cyber threats.

What role does communication play in cyber incident response?

Communication is a key element in the success of any cyber incident response. It involves timely and clear communication within the incident response team, as well as with stakeholders, management, and potentially affected parties. Effective communication ensures that everyone involved is informed about the nature of the incident, the steps being taken to address it, and the expected outcomes.

In the case of significant incidents, communication also extends to external parties, such as customers, partners, regulatory bodies, and the public. This aspect of communication must be handled carefully to maintain trust and transparency, while also protecting sensitive information. A well-prepared communication plan, which outlines protocols for internal and external communications, is essential in managing the incident efficiently and maintaining the organisation's reputation.

What technologies are crucial for effective cyber incident response?

Effective cyber incident response relies on a range of technologies. These include advanced threat detection systems, such as intrusion detection systems (IDS) and security information and event management (SIEM) solutions, which provide real-time monitoring and alerts. Other crucial technologies include forensic analysis tools to investigate and understand the nature of the threat, and incident management platforms to coordinate response efforts.

Additionally, automated response tools can help contain and mitigate threats quickly, while data backup and recovery solutions are essential for restoring affected systems. The integration of these technologies, along with continuous monitoring and analysis, forms the backbone of an effective cyber incident response capability.
