Challenges and Best Practices Explore our curated learning milestones for you! Financial services cybersecurity protects customer information, payments, and access to financial services. Phishing, ransomware, vulnerable applications, and compromised providers can put all three at risk.

How it works

  • The requirements you must meet depend on where you operate, what you do, and the data you handle.
  • Learn 21+ in-demand cybersecurity skills, including ethical hacking, system penetration testing, AI-powered threat detection, network packet analysis, and much more with Masters in Cyber Security.
  • Identify Critical Services and Assign Risk Owners Identify the systems, people, data, and external providers that help the service operate for payments, account access, trades, lending, or claims processing.
  • Organize work on Govern, Identify, Protect, Detect, Respond, and Recover using NIST CSF 2.0.
  • Identity and access management helps you limit employees to the records and functions their work requires.

What to take from it

Financial services cybersecurity means understanding where those risks sit and what you can do about them. You need to test its connections, schedule downtime, and assign someone to manage the risk until the fix is complete. Review these problems alongside attacks that slipped through so you know where to adjust your controls.

Example or evidence

  • Consider what test datasets, backups, and copies owned by suppliers might expose.
  • Don't put unnecessary sensitive information in logs or development datasets, and remove it securely once legal and business requirements allow.
  • You need strong access controls, secure systems, and recovery plans your team has tested.
  • Your customers expect to access their accounts, make payments, and trust that their information is safe.
