Identify, Evaluate, Remediate

Detecting a cyber attack quickly, responding effectively and learning lessons from the incident are fundamental principles of a robust – and compliant – cyber security strategy.

However, few organizations’ incident response mechanisms have kept pace with the prevalence and sophistication of modern cybercrime or the evolution of data governance regulations, such as the EU General Data Protection Regulation (GDPR) or similar federal laws across the US.

Effective cyber security incident response (CSIR) requires a combination of digital forensics, business continuity and information security management procedures. With the right measures in place, you are more likely to detect attacks quickly (while they are still underway), minimize their impact, mitigate your risk – and meet regulatory requirements.

Eight Types of Security Incidents

There are various types of security incidents that organizations may encounter, each with its own unique characteristics and potential impact. Here are eight common types of security incidents:

Malicious software (malware) infects systems, causing damage or unauthorized access.

Examples: Viruses, worms, Trojans, ransomware, spyware.

Attackers gain unauthorized access to systems, networks, or data.

Examples: Brute force attacks, password cracking, privilege escalation.

Sensitive or confidential data is accessed, stolen, or exposed without authorization.

Examples: Personal information, financial data, intellectual property theft.

Attackers manipulate individuals into revealing sensitive information, clicking malicious links, or performing actions that compromise security.

Examples: Phishing emails, spear phishing, pretexting, baiting.

Attackers overwhelm systems or networks to disrupt service availability, rendering them inaccessible to users.

Examples: Flood attacks, Distributed DoS (DDoS) attacks.

Employees, contractors, or other trusted individuals misuse their access to compromise security.

Examples: Data theft, unauthorized access, sabotage.

Unauthorized individuals gain physical access to restricted areas, equipment, or facilities.

Examples: Tailgating, unauthorized entry, theft of physical assets.

Weaknesses in software, systems, or network configurations are exploited by attackers.

Examples: Exploiting unpatched vulnerabilities, misconfigured databases.

The Six Phases of the Incident Response Lifecycle

This involves creating and maintaining an incident response policy, assembling a dedicated incident response team, defining roles and responsibilities, and establishing communication channels both within the team and with external stakeholders.

The incident response team works to identify potential security incidents or breaches. This includes gathering data from various sources such as intrusion detection systems, logs, network traffic analysis, and reports from users. The team analyses this data to determine if there are any anomalies or indicators of compromise. The goal is to detect incidents as early as possible to minimise potential damage.

Once an incident is confirmed, the focus shifts to containing the impact and preventing further damage. Containment involves isolating affected systems, restricting access, and implementing temporary solutions to prevent the incident from spreading.

In this phase, the team works to eliminate the root cause of the incident. This often involves a thorough investigation to identify how the attacker gained access, what vulnerabilities were exploited, and what malware or malicious activities were involved. The team then develops a strategy to remove the attacker’s presence from the affected systems and implements necessary security patches or configuration changes to prevent similar incidents in the future.

After the threat is neutralised, the focus shifts to recovering affected systems and returning them to normal operation. This may involve restoring data from backups, verifying the integrity of systems, and ensuring that the systems are functioning as intended. The recovery process aims to minimise downtime and restore normal business operations as quickly as possible while ensuring that the systems are secure.

The incident response team conducts a thorough post-incident analysis to understand what worked well and what could be done better. This includes evaluating the effectiveness of the response, communication, and coordination, as well as assessing the overall impact of the incident on the organisation. The insights gained from this phase are used to update incident response plans, refine security measures, and enhance the organisation’s overall cybersecurity posture.
