    This study aims to measure the classification accuracy of XSS attacks by using a combination of two methods of determining feature characteristics, namely using linguistic computation and feature selection. XSS attacks have a certain pattern in their character arrangement, this can be studied by learners using n-gram modeling, but in certain cases XSS characteristics can contain a certain meta and synthetic this can be learned using feature selection modeling. From the results of this research, hybrid feature modeling gives good accuracy with an accuracy value of 99.87%, it is better than previous studies which the average is still below 99%, this study also tries to analyze the false positive rate considering that the false positive rate in attack detection is very influential for the convenience of the information security team, with the modeling proposed, the false positive rate is very small, namely 0.039%This study aims to measure the classification accuracy of XSS attacks by using a combination of two methods of determining feature characteristics, namely using linguistic computation and feature selection.

    Gradualmente, tem-se vindo a verificar que a informação pertencente aos diversos utilizadores da Internet está cada vez mais exposta a ataques. Estas invasões comprometem os seus dados, e, para isso, têm surgido algumas respostas, tais como a segurança da informação. Um dos fatores que se destaca e que está relacionado com esta é a autenticidade. Técnicas de biometria e chaves eletrónicas são exemplos usados para a assegurar, na informação. Porém, o mecanismo que mais sobressai é a utilização de um par constituído por nome de utilizador e palavra-chave. Contudo, este tem revelado alguns problemas associados. Ora, se é usado um único segredo para salvaguardar todos os recursos privados, e este é descoberto, a informação do utilizador estará inteiramente comprometida. Já no caso de serem empregues múltiplas passwords, corre-se o risco de haver o esquecimento das credenciais de acesso. Por outro lado, existem inconvenientes se estas são curtas (facilmente encontradas) ou longas (difíceis de memorizar). Dadas as situações relatadas, têm vindo a ser aplicados gestores de palavras-chave. Tais métodos permitem o armazenamento dos segredos, bem como a sua criação, podendo estes ter vários tipos de resoluções, variando entre técnicas locais, móveis, ou até mesmo baseadas na web. Todas elas possuem vantagens (dependendo do cenário), assim como desvantagens comuns. De forma a verificar se estas ferramentas disponibilizam a segurança prometida, foi executada uma análise intensiva a alguns programas, escolhidos pelo seu desempenho e notoriedade, que já se encontram no mercado. Caso não se mostrassem eficazes, seria proposta uma aplicação, com vista a resolver os problemas descobertos. Porém, concluiu-se que já existe um mecanismo que oferece a salvaguarda pretendida. Assim, foi feito unicamente um estudo sobre as abordagens que podem ser adotadas, destacando a que se apresentou como mais adequada.It has been verified, gradually, that information belonging to different Internet users, is increasingly exposed to attacks. These invasions compromise their data, and so, some answers have arisen, such as information security. One of the most important factors, related to this concept, is authenticity. Biometrics and security tokens are examples used to ensure it. However, the mechanism that stands out more, is the pair composed by a username and password. Nevertheless, this has revealed some problems. If a single secret is used to protect all the websites, and it’s discovered, users’ information will be fully compromised. If there are used multiple passwords, there may be a risk of forgetting access credentials. On the other hand, there are drawbacks if they are short (easily found) or long (hard to remember). Considering the reported statements, password managers have been applied. Such methods allow to store and generate passwords, and can have different types of solutions, ranging between local, mobile or even web-based. All of these have advantages (depending on the scenario), as well as common disadvantages. In order to check if these tools offer the promised security, it was performed an intensive analysis to some programs, chosen by their performance and reputation, that are already on the market. If they proved to be ineffective, an application to solve the discovered problems would be proposed. However, it was concluded that a mechanism providing the desired protection, already exists. Thereby, it was only conducted a study about the approaches that can be adopted, pointing out the one that was presented as more appropriate
