Description:The development of a prototype of computer audits has become more
important for the administration and auditors of public companies. In
this study, crucial control elements were explored to meet the safety
conditions that a public company must have; In addition to the
development of a computer audit prototype based on recognized control
elements and validate the applicability of the prototype through the use
of a model to meet the needs of a public organization in Ecuador. The
general objective of this research was to develop a computer audit
protocol, for this a method was used in a Cryptographic Algorithm,
giving as a better option for its understanding a flow chart with the
encryption processes that resulted in vulnerability mitigation. within
the access to information. In the experimental aspect, studies were
conducted based on the evaluation criteria of ISO / IEC 9126 software,
the result of which showed that the prototype can provide the internal
audit staff of the public institution and its external auditors with a
simple, continuous, timely and appropriate analysis. analytical, which
can help quickly and effectively detect organizational control problems.
This study can contribute to the development of a sufficient and
manageable computer audit system, and provide future researchers and
companies with guidance in this thematic area. Given the diversity of IT
(Information Technology), within such a document it is not possible to
be specific about computer auditing in particular sectors or in relation
to specific hardware or software.
