This research presents an analysis over the most common cyber-attacks, the vulnerabilities that they depend on and the possible mitigation solutions together with the complementary implementation of one or multiple proposed solutions in the INTELLIT platform. This platform will contribute for preserving and highlighting the Romanian literary heritage. The analysis presents applied solutions for the software level and own application code. We present some general security practices, as well as measures taken in each particular case of vulnerability and adding also a few generic tips to increase the protection against malicious attacks.
