- Intrusion Detection and Prevention Systems (IDS/IPS): These systems monitor network traffic for suspicious activity and automatically block or alert security personnel to potential threats.
- Virtual Private Networks (VPNs): VPNs encrypt network traffic, providing secure remote access to bank systems.
- Network Segmentation: Dividing the network into smaller segments limits the impact of a security breach.
- Endpoint Security:
- Antivirus and Anti-Malware Software: This software protects computers and devices from malware infections.
- Endpoint Detection and Response (EDR): EDR solutions provide advanced threat detection and response capabilities, including threat hunting and incident response.
- Device Management: Banks manage and secure devices used by employees, including laptops, smartphones, and tablets.
- Data Security:
- Data Encryption: Data encryption protects sensitive data from unauthorized access, both at rest and in transit.
- Data Loss Prevention (DLP): DLP systems monitor and prevent the unauthorized disclosure of sensitive data.
- Data Backup and Recovery: Regular data backups ensure that data can be restored in the event of a system failure or data breach.
- Identity and Access Management (IAM):
- Multi-Factor Authentication (MFA): MFA requires users to provide multiple forms of identification, making it more difficult for attackers to gain unauthorized access to accounts.
- Role-Based Access Control (RBAC): RBAC restricts access to systems and data based on an employee’s job role.
- Privileged Access Management (PAM): PAM solutions manage and secure privileged accounts, which have elevated access to bank systems.
- Security Awareness Training:
- Employee Training: Banks provide regular security awareness training to employees to educate them about cyber threats and best practices for protecting sensitive information.
- Phishing Simulations: Banks conduct phishing simulations to test employees’ ability to identify and avoid phishing attacks.
- Incident Response:
