Secure by Default

We believe that technology should be Secure by Default. This means embedding security from inception, so that it is intrinsic and as transparent as possible.

Good technical design is security design

Secure by Default takes a holistic approach to solving security problems. Security is treated as a core fundamental rather than a followup activity.

Embedding security within a design is directly comparable to good modern technical designs and fundamentally ensuring the ‘thing’ actually works.

Secure by Default

The National Cyber Security Centre (NCSC) describe the Secure by Default principles as:

  • security should be built into products from the beginning, it can’t be added in later;

  • security should be added to treat the root cause of a problem, not its symptoms;

  • security is never a goal in and of itself, it is a process - and it must continue throughout the lifetime of the product;

  • security should never compromise usability - products need to be secure enough, then maximise usability;

  • security should not require extensive configuration to work, and should just work reliably where implemented;

  • security should constantly evolve to meet and defeat the latest threats - new security features should take longer to defeat than they take to build;

  • security through obscurity should be avoided;

  • security should not require specific technical understanding or non-obvious behaviour from the user.

Context is important

The previous principles can generally be applied in most scenarios however interpretation and applicability in context can vary - the Ministry of Justice (MoJ) Cyber Security team are here to help and advise.

NCSC also have a set of whitepapers which help explain some approaches to building products which align with these principles (and they add to them over time):
