Security begins with planning
Before development starts, teams should understand what information the system will handle, who needs access, which services it depends on, and what could happen if those resources are exposed or unavailable.
Use the principle of least privilege
Users, applications, and administrators should receive only the access required for their responsibilities. Limiting unnecessary permissions reduces the impact of mistakes and compromised accounts.
Protect data in transit and at rest
HTTPS and appropriate encryption help protect information as it moves between systems and when sensitive data is stored. The exact controls should reflect the type of information being handled and the risks involved.
Validate what enters the application
Forms, APIs, uploads, and other inputs should not automatically be trusted. Validation and careful error handling help reduce malformed requests and common application security problems.
Maintenance is part of security
A secure launch is not the end of the process. Dependencies, platforms, permissions, logs, and configurations should be reviewed and updated as technology and threats change.
Combine prevention with visibility
Preventative controls are stronger when organizations can also identify unusual activity. Logging, monitoring, backups, and response procedures support business continuity when something does go wrong.
