Types of Security Incidents in Financial Services Industry

Understanding the various types of security incidents is crucial for effective reporting. Common incidents in the financial sector include:

Data Breaches  

Unauthorized access to sensitive customer information, such as account details or personal data. These can result from external hacking attempts or internal vulnerabilities. The impact of data breaches can be severe, often leading to financial losses, reputational damage, and regulatory penalties.

Malware Infections  

Malicious software that compromises system integrity or steals data. This can include viruses, trojans, ransomware, and other forms of harmful code. Malware can spread rapidly through networks, potentially affecting multiple systems and compromising large amounts of data.

Phishing Attacks  

Fraudulent attempts to obtain sensitive information by posing as a trustworthy entity. These attacks often target both employees and customers, using sophisticated social engineering techniques. Phishing can lead to credential theft, financial fraud, and serve as an entry point for more complex attacks.

Insider Threats  

Security risks originating from within the organization, either malicious or unintentional. This could involve employees misusing access privileges, falling for social engineering tactics, or intentionally stealing data. Insider threats are particularly challenging to detect and can cause significant damage due to the perpetrator's internal access and knowledge.

Denial of Service (DoS) Attacks

Attempts to disrupt normal traffic to a service, often targeting online banking platforms. These attacks can overwhelm systems, making services unavailable to legitimate users. DoS attacks can result in significant operational disruptions and customer dissatisfaction, potentially leading to financial losses and reputational damage.

Unauthorized Access  

Any instance where an individual gains access to systems or data without proper authorization. This could result from weak access controls, stolen credentials, or exploitation of system vulnerabilities. Unauthorized access can lead to data theft, system manipulation, or serve as a stepping stone for more severe breaches.

The Federal Financial Institutions Examination Council (FFIEC) Cybersecurity Resource Guide provides detailed information on various types of cyber incidents relevant to financial institutions.

Regulatory Framework for IT Security Incident Reporting

Financial institutions must navigate a complex regulatory landscape when it comes to incident reporting. Key regulations include:

Gramm-Leach-Bliley Act (GLBA)  

Requires financial institutions to implement safeguards to protect customer information and notify customers of breaches. The GLBA also mandates that financial institutions develop a written information security plan that describes their program to protect customer information.

Sarbanes-Oxley Act (SOX)  

Mandates strict internal controls and reporting requirements for financial institutions. While primarily focused on financial reporting, SOX has significant implications for IT security and data integrity, requiring companies to establish and maintain effective internal controls over financial reporting.

State-Specific Regulations  

Many states have their own data breach notification laws. For example, the New York Department of Financial Services Cybersecurity Regulation imposes strict reporting requirements on financial institutions operating in the state. These state-level regulations often have specific timelines and procedures for reporting incidents, which can vary significantly from state to state.

Federal Reporting Requirements

FFIEC Guidelines  

The FFIEC Cybersecurity Assessment Tool provides a framework for evaluating cybersecurity preparedness, including incident response and reporting. This tool helps financial institutions identify their risks and determine their cybersecurity maturity, guiding them in establishing appropriate incident reporting processes. In 2024, FFIEC announced it will be sunsetting the CAT tool in 2025. For more information read our full Cybersecurity Assessment Guide.

SEC Requirements  

Publicly traded financial institutions must comply with Securities and Exchange Commission (SEC) reporting requirements for material cybersecurity incidents. These requirements include timely disclosure of significant cybersecurity incidents that could impact investor decisions, emphasizing the need for robust incident detection and reporting mechanisms.  

SANS Institute Incident Report Structure

The SANS Institute, a respected authority in information security, recommends a comprehensive structure for incident reports.

This structure can be adapted for use by financial institutions:

• Executive Summary - A high-level overview of the incident, its impact, and key findings.
• Incident Description - Detailed account of the incident, including affected systems and data.
• Response Actions - Steps taken to contain and mitigate the incident.
• Timeline of Events - Chronological breakdown of the incident and response activities.
• Findings and Analysis - In-depth examination of the incident's cause and impact.
• Recommendations - Actionable steps to prevent similar incidents and improve security posture.
• Lessons Learned - Insights gained from the incident and response process.
• Appendices - Technical details, evidence, and supporting documentation.
