The Challenge
A privileged account at a financial institution triggered an alert within their SIEM (Security Information and Event Management) provider. The suspicious activity involved several unsuccessful login attempts followed by a successful login from an unfamiliar IP address, occurring outside of usual business hours. This indicated a possible brute-force attack or unauthorized access attempt on crucial servers.
For financial institutions, the compromise of a privileged account is an extreme risk, often leading to catastrophic data breaches, major financial losses, and non-compliance with stringent regulatory requirements. Rapid detection and response are paramount to protecting customer funds and maintaining trust.
Failure to promptly detect and respond to this unauthorized access would have resulted in a severe security breach, exposing critical assets and sensitive customer data, and likely incurring heavy regulatory fines.
The Solution
The Cybervergent SIEM solution supported the security team to execute immediate, targeted, and comprehensive remediation steps, including:
Containment: The affected servers were immediately isolated from the network to prevent the unauthorized access from spreading to other assets.
Account Management: The compromised privileged account was promptly disabled, and its password was reset to prevent further abuse of credentials.
Root Cause Analysis: A thorough investigation, including log analysis and forensic work, was conducted to determine the root cause of the unauthorized access and identify all irregular activity.
Security Hardening: Cybervergent guided the implementation of security best practices, including enforcing the Principle of Least Privilege and conducting periodic reviews of access control lists to limit access to critical data.
Security Awareness: The incident reinforced the need to foster a culture of security awareness through regular training on safeguarding credentials.
The Results
By leveraging the capabilities of Cybervergent's SIEM solution, the financial institution achieved its objective of securing its organizational assets. The swift action ensured the integrity of critical data and systems by:
- Preventing Data Loss: The immediate isolation and account disablement successfully contained the attack and prevented a security breach from escalating.
- Maintaining Integrity: The organization mitigated the risk of unauthorized access attempts and maintained the security and integrity of its assets.
- Strengthening Defenses: The analysis helped implement additional security measures and enforce the principle of least privilege, proactively strengthening defenses against future brute-force attacks.
