New technologies in everyfield prove that users need security features integrated into theircommunication applications, parallel systems for mobile devices,internet, and identity management. This review presents the keyconcepts of the main areas in computer security and how it hasevolved in the last years. This work focuses on cryptography,user authentication, denial of service attacks, intrusion detectionand firewalls.

This Paper includes a brief theoretical analysis of the reasons for their use from the cryptography viewpoint, the evolution of the system in its presentation for the users, focusing on the strongest CAPTCHA in the market. Additionally, a review of the technology that has allowed to break the system at certain level and the evolution of Artificial Intelligence systems in the medium term could defeat CAPTCHA; to finally make recommendations on how to design and maintain a strong CAPTCHA at short and medium term against the evolution of technology and what kind of features should hav...

Along the time, most of electronic mails have been sent between users in a way that any user, intended or not, could read the message or impersonate a sender. To resolve all these issues and maintain the privacy of e-mails was the reason for the creation of PGP and its complements. However, over the years, PGP revealed unexpected security issues when faced to mistrusted environments where we do not know if someone is who claims to be. To overcome this problem, we propose a trust solution for OpenPGP that improves trust relationships between users and the public key distribution network. Our proposal could be implemented in a system using cryptographic technology efficiently in OpenPGP over an all-new trust approach.
