Financial communication systems—VoIP,video conferencing,and messaging—are frequent targets for cyberattacks.Regular security audits are critical to identifying vulnerabilities before they’re exploited.Here’s how to conduct an effective audit.
Step 1:Define Scope and Objectives
Clarify what you’re auditing:
-Systems:VoIP servers,gateways,UC platforms(e.g.,Redstone NewLync 2.0),and endpoints(phones,softclients).
-Risks:Focus on high-impact threats(call interception,data breaches,regulatory non-compliance).
-Regulations:Align with standards like PCI DSS(payment calls),ISO 27001,and region-specific rules(e.g.,GDPR).
Step 2:Assess Network and Access Controls
-Port Security:Check for open default ports(e.g.,SIP 5060),which are easy targets.Redstone lets you customize ports to avoid this.
-IP Whitelisting:Verify that only authorized IPs can access admin interfaces.Audit logs to spot unauthorized access attempts.
-Authentication:Ensure multi-factor authentication(MFA)is enabled for admin accounts and that passwords meet complexity requirements.
Step 3:Evaluate Encryption and Data Protection
-In-Transit Encryption:Confirm TLS 1.3(signaling)and SRTP(voice)are active—no unencrypted calls should occur.
-Storage Encryption:Check that recordings are encrypted(AES-256)and that only authorized users can access them.
-Data Sovereignty:Ensure data isn’t stored in regions violating regulations(e.g.,EU data in the U.S.without GDPR safeguards).
Step 4:Test for Vulnerabilities
-Penetration Testing:Simulate attacks(SIP floods,call interception)to identify weak points.Redstone’s SBCs(session border controllers)are designed to block such attacks—verify they’re configured correctly.
-Software Updates:Check that all systems(servers,gateways,endpoints)have the latest patches.Outdated firmware was responsible for 60%of financial breaches in 2023(IBM report).
Step 5:Review Compliance and Audit Trails
-Recording Compliance:Confirm retention periods match regulations(e.g.,7 years for MiFID II)and that recordings are unaltered.
-Audit Logs:Ensure logs track all actions(calls,admin changes)and are stored securely for 1+years.Redstone’s UMS automates log management.
Step 6:Remediate and Monitor
-Fix Critical Issues First:Prioritize vulnerabilities like unencrypted calls or open ports.
-Update Policies:Revise access controls,encryption standards,and update procedures based on findings.
-Continuous Monitoring:Use tools like Redstone’s intrusion detection system to spot threats in real time.
By conducting regular audits,financial institutions turn security from a one-time project into an ongoing process—protecting sensitive data,maintaining compliance,and preserving customer trust.
