## 10. Security Considerations

### 10.1 RDMA Security
```java
public class RdmaSecurityManager {
    public void validateMemoryAccess(RdmaMemoryRegion region, RdmaAccess requestedAccess) {
        if (!region.hasAccess(requestedAccess)) {

Aber in realen Fällen würden Sie bei der Implementierung von Sicherheit mehr Vorteile durch die Verwendung der integrierten [Sicherheits-Werkzeuge (siehe nächstes Kapitel)](../security/index.md){.internal-link target=_blank} erzielen.
