Incident response in the field of cybersecurity is a set of measures aimed at detecting, analyzing, and stopping unwanted or malicious actions that may threaten the information security of organizations, companies, or individual users.
This service covers a wide range of activities that our team is ready to perform to detect and handle incidents in networks, systems, and applications. Key aspects of incident response include:
-
Incident Detection: Continuous monitoring and analysis of network activity and events to identify suspicious or abnormal actions that may indicate a cyber attack.
-
Incident Response: This is the process of responding to detected incidents. Cybersecurity analysts and specialists begin investigating the incident to understand its nature, scope, and impact on systems.
-
Threat and Vulnerability Analysis: Upon detecting an incident, a thorough analysis of the threat, used malware, and identified vulnerabilities is conducted. This helps develop an effective plan to eliminate the incident and prevent its recurrence.
-
Incident Containment: Cybersecurity specialists take measures to stop the attack, isolate infected systems, and clean them from malicious code. This may also involve ensuring uninterrupted system operation during the incident response.
-
Incident Recovery: After eliminating the threat and restoring normal system operation, an analysis of the incident's root causes is performed, and measures are taken to prevent its recurrence.
-
Forensics and Analysis: Conducting digital forensics to identify the source of the attack, the methods used, and the exploitation of vulnerabilities. This helps strengthen defense for the future.
-
Continuous Improvement: After the incident is resolved, the cybersecurity team analyzes the event and identifies weaknesses in security systems for subsequent improvement and protection enhancement.
EXAMPLE:
Let's consider a scenario where a small business seeks incident response services:
Scenario: Cyber Attack on a Small Business
Imagine a small company engaged in online retail, selling furniture and home accessories. They have an e-commerce website, a customer database, and an online payment system. The company traditionally had some security measures in place but lacked a robust cybersecurity infrastructure.
Incident Response Steps:
Step 1: Incident Detection
- The internal monitoring system detects unusual requests to the database.
- The company notices abnormal system behavior manifested in unexplained performance degradation.
Step 2: Incident Notification
- The company manager contacts external cybersecurity specialists and informs them about the suspicious activity.
Step 3: Investigation and Analysis
- Cybersecurity experts begin analyzing the activity, examining event logs, and gathering information about the incident's scope.
- Malicious code on the web server is quickly discovered, utilizing a vulnerability in the online store platform.
Step 4: Incident Containment
- Cybersecurity specialists promptly take action to remove the malicious code and address the vulnerability.
- Temporary access restrictions are imposed to minimize downtime while fully resolving the incident.
Step 5: Recovery
- After mitigating the vulnerability and removing the malicious code, the online store is restored and made available to customers.
- The company implements additional security measures to prevent similar incidents in the future.
Step 6: Forensics and Analysis
- Cybersecurity experts conduct forensic analysis to determine how the attack occurred and potential perpetrators.
- Recommendations are provided to enhance security to prevent similar incidents in the future.
Step 7: Training and Improvement
- The company conducts training for its employees on methods to prevent cyber attacks and improve overall cybersecurity.
As a result of professional incident response, the small business can quickly recover from the attack and take measures to strengthen its cybersecurity, preventing future threats and ensuring the security of its customers and data.
