Think of a stock exchange or a big payment system. These are financial market infrastructures (FMIs). They move money around the world every second.
A cyber attack here is not just about stolen data. It can freeze the whole financial system. That is why resilience testing is a big deal.
We need to test these systems in a smart way. Not just checking boxes, but simulating real attacks. The goal is to see if they can survive and keep running.
| Framework | Region | Main Focus | Who Runs It |
|---|---|---|---|
| TIBER-EU | European Union | Threat-led penetration testing | National central banks |
| CBEST | United Kingdom | Intelligence-led testing | Bank of England |
| AASE | Singapore | Adversarial attack simulation | Monetary Authority of Singapore |
| CORIE | Australia | Cyber operational resilience | Council of Financial Regulators |
Different countries use different frameworks. But they all share one idea: test like a real attacker would.
You cannot just use a generic checklist. The test must match the specific threats your country faces.
These frameworks sound complex. But the core idea is simple. You hire a team to act like bad guys.
They try to break in, using the same tricks real hackers use. The company being tested does not know the full plan ahead of time.
A big bank in Europe used TIBER-EU. The testers pretended to be a criminal group. They sent fake emails to employees, trying to get passwords. It worked on the first few people. The bank learned it needed better training, fast.
The testers look for weak spots. They find them in technology, but also in people.
Maybe an employee clicks a bad link. Or maybe a server is missing a security patch. The test finds it all.
| Scenario Type | What the Attacker Does | Target Example | Goal of the Test |
|---|---|---|---|
| Phishing Campaign | Sends fake emails to steal logins | Employee workstations | Check staff awareness and email filters |
| Ransomware Deployment | Locks critical files and demands payment | Database servers | Test backup and restore speed |
| DDoS Attack | Floods network with traffic to cause crash | Public-facing website | See if network defenses hold up |
| Supply Chain Compromise | Hides malware in a software update | Third-party vendor software | Check third-party risk controls |
After the test, you get a report. It shows what went wrong and what was okay.
But the report is not the finish line. It is just the start of the real work. You need to fix the problems found.
A payment processor in Asia did a test. The testers found an old server that everyone forgot about. It had no security updates. It was like a wide-open back door to the main network. They fixed it in one day after the test.
Finding holes is good. Fixing them is essential. A test without a remediation plan is just a scary story.
Companies must plan time and money to fix the critical issues first, right after the test ends.
The regulators are watching closely now. They expect these tests to happen regularly.
It is not a one-time event. You must do it again and again. Threats change, and new weak spots appear all the time.
| Step Name | Key Activities | Who is Involved | Duration |
|---|---|---|---|
| 1. Scoping | Define what systems to test, and what is off-limits | Firm and regulators | 1-2 months |
| 2. Threat Intelligence | Gather info on likely real-world attackers | Test providers and intel teams | 1-3 months |
| 3. Testing Phase | Conduct the actual simulated attacks | Red team (attackers) | 2-4 months |
| 4. Remediation | Fix the weaknesses that were found | Firm's IT and security teams | 3-6 months (or longer) |
The whole process can take a year. It needs a lot of trust between the bank and the testers.
You are giving a team permission to attack you. That is a scary but necessary thought.
One core idea is to protect the "crown jewels." These are the most important systems. If they stop, the whole business stops.
For a stock exchange, the crown jewel is the matching engine. It pairs buyers and sellers. The test focused 80% of its effort on protecting just that one system. Everything else was secondary.
You cannot protect everything equally. Find the 2 or 3 critical systems that would cause a crisis if they failed.
Put your best people and money on keeping those crown jewels safe and quick to recover.
Getting the board of directors to care is a big challenge. They often see this as just a tech cost.
But they need to see it as a business survival cost. A bad cyber day can end a company.
| Role | Main Responsibility | Required During | Mindset |
|---|---|---|---|
| Board Members | Approve budget and understand top risks | Start and closure | Strategic oversight |
| CISO (Chief InfoSec Officer) | Oversee the entire test safely | All phases | Guardian and coordinator |
| Blue Team (Defenders) | Detect and respond to attacks in real time | Testing phase | Not panicking, learning |
| Red Team (Attackers) | Simulate real criminal tactics | Testing phase | Creative and persistent |
The blue team should not feel punished if they fail to stop an attack during a test. The test environment is meant to be hard.
It is a learning game. The score does not matter. The lessons learned are what count.
One IT manager was stressed before a CBEST test. The red team broke in quickly. At first he was upset. Then he realized they used a new trick that no one on his team had seen before. He was grateful to learn it in a test, not a real attack.
If teams are scared of failing a test, they will hide problems instead of fixing them.
Frame the test as a free lesson from top experts, not a pass-or-fail exam. This gets the best results.
In the end, cyber resilience is about bouncing back. You must assume you will be hit one day.
Can you still process payments? Can you still settle trades? That is the real test of strength.
Key Takeaways
| Key Point | What It Means | Action Item |
|---|---|---|
| Go beyond basic checks | Threat-led testing is the new global standard | Start planning a TIBER-EU or CBEST test now |
| Fix what you find | A test report is useless without a solid fix plan | Create a dedicated remediation team post-test |
| Protect crown jewels | Focus limited resources on the most critical FMIs | Identify your top 3 systems that must never fail |
| Test people, not just tech | Many breaches start with a simple human error | Run phishing simulations and training every month |
| It's a cycle, not a project | Cyber threats evolve fast; tests must be regular | Schedule a new test every 1-2 years at minimum |
