Banking, engineered to be defended.
Biira Bank is a fictional institution, built from the network up as a working demonstration of how a modern bank secures identity, infrastructure and every transaction in between.
Security is not a feature here. It is the foundation.
Every layer of the bank is designed around a single assumption: that an attacker is already inside. What follows is how the damage is contained.
Segmented by zone
Customer systems, back-office, monitoring and administration each live on their own isolated network. A breach in one cannot walk into the next.
Identity you can prove
Every person and every service authenticates against a central directory, with least-privilege access and multi-factor sign-in for anything sensitive.
Watched in real time
A security operations pipeline collects and correlates events across the whole estate, so unusual behaviour is seen while it happens, not weeks later.
Encrypted end to end
Traffic to and from the bank is protected in transit, with strong TLS, strict transport security and headers hardened against common web attacks.
Measured against a standard
Systems are hardened to recognised benchmarks and re-checked over time, so security is a number that improves, not a claim that goes stale.
An edge that thinks
A web application firewall sits in front of everything, filtering malicious requests, throttling abuse and absorbing attacks before they reach the bank.
Biira Bank is not real. The engineering is.
There is no vault, no money and no customers. Biira Bank is a fictional institution invented as a realistic target to build, break and defend, the visible front of a full enterprise security lab.
- No real accounts, balances or personal data are ever collected
- Every control shown here is genuinely built and documented
- The lab spans identity, network, monitoring and cloud security
