Abstract
As applications increasingly handle sensitive and
personal information, ensuring the security of this data has
become a critical concern across industries such as finance,
healthcare, and e-commerce. Traditional security mechanisms
that rely on single-point protection models are no longer
sufficient to mitigate the growing complexity and frequency of
cyber threats. This paper presents a comprehensive Layered
App Security Architecture aimed at safeguarding sensitive
data through a multi-tiered defense approach. The proposed
framework incorporates security controls at every architectural
layer, from the user interface to the backend data storage
systems, aligning with the principles of defense-in-depth and
zero trust.
