In cybersecurity, there is no such thing as being too prepared. The larger the company and the more sensitive the data it handles, the stronger its security team must be. This dedicated department is responsible for developing and implementing the company’s security strategy, working closely with other teams to ensure robust protection.
In today’s article, Amir Aliev, Head of Infrastructure Security and Operations, delves into the crucial profession of cyber security, focusing on Incident Response Analyst roles and responsibilities.
An Incident Response Analyst is a key player in any security team. Understanding the Incident Response Analyst’s salary can also provide insight into the value of these experts within the industry. Their primary role is to efficiently manage all security incidents: to thoroughly investigate incidents from start to finish, ensuring no detail is overlooked, while simultaneously implementing countermeasures to thwart attackers and prevent further attack development. This includes responsibilities typically associated with Incident Management Analysts and Security Incident Response Analysts.
This specialist must be a ‘universal soldier’ in cybersecurity, possessing a deep understanding of various security aspects, strong analytical skills, and the ability to perform under pressure in emergencies. Their expertise often extends to incident response team roles, which include coordination, communication, and direct action during and after security incidents.
Trends in Incident Response Analytics
Incident Response Analyst: skills, roles, requirements | SOFTSWISS CareersConsider the illustrative case from February, where a corporate manager in Hong Kong voluntarily clicked on a suspicious link and transferred USD 25 million to scammers. Using deepfakes during a call, these scammers created convincing images of the manager’s colleagues and superiors. This incident underscores the dangerous combination of AI, social engineering, and phishing, a trend that, unfortunately, is poised to grow.
On the flip side, AI tools can also be employed for defence. The side with more advanced specialists will invariably have the upper hand. Leaders are re-evaluating security budgets in the current climate of global economic uncertainty. To ensure optimisation rather than unnecessary cuts, leaders must formulate a personalised cyber defence strategy in collaboration with CTOs and security team heads. This involves accurately assessing actual and potential risks and utilising the budget effectively.
Gartner predicts that by 2026, 70% of boards will have at least one subject matter expert in cybersecurity. This will enhance the implementation of cybersecurity strategies, enabling organisations to transition from reactive to proactive measures.
What Does an Incident Response Analyst Do?
Analytics
An Incident Response Analyst is a critical player in cybersecurity, leveraging various security systems to meticulously compare events, investigate incidents, and identify anomalies in system and employee behaviour. They aim to detect deviations from the norm and plan response activities for suspicious or dangerous events. Alerts may come from security systems like SIEM, EDR, and NTA or employees reporting strange emails, instant messages, or unusual computer activity. The analyst’s crucial task is to differentiate real threats from normal system behaviour.
Incident Response
1. Threat Assessment and Evaluation of Potential Consequences
Analysts evaluate the potential impact of the threat to prioritise response actions effectively.
2. Action Plans and Playbooks
The analyst then follows a predefined action plan (playbook) to address specific types of threats. If no suitable playbook exists, a new action plan is created tailored to the unique aspects of the threat.
3. Identifying the Initial Penetration Vector
Identifying the initial penetration vector – the security gap that enabled the attack – is essential. Understanding how the attacker breached the security perimeter helps in fortifying defences and preventing similar future incidents.
4. Mitigation of Identified Threats
When a threat bypasses existing security measures and is detected through alternative means, the analyst prioritises actions to mitigate its impact. This includes stopping the threat, preventing its escalation, and addressing critical events such as monetary theft, data breaches, or trade secret leaks.
5. Strengthening the First Line of Defence
The ‘first line of defence’ must have robust mechanisms to counter threats actively, not just monitor them. This proactive approach is essential for a resilient cybersecurity posture.
Collaboration with Other Experts
The analyst interacts with management, IT, development, and legal departments to address vulnerabilities and mitigate the consequences of an attack. In the case of serious incidents, they also assist law enforcement agencies. Additionally, recommendations often include improving monitoring rules for security systems. In in-house teams, IR analysts may also handle such corrections, cover new event sources/systems with regulations, and implement other monitoring engineering improvements.
By leveraging their skills and working collaboratively with other departments, Incident Response Analysts play a vital role in maintaining the security and integrity of an organisation’s systems and data.
