Eight Factors to build more secure and performance software

Introduction

Moderation factors can be seen as “one that actively contributes to the production of a result.” This post presents eight moderation factors regarding security and performance verification of software systems. In other words, they are Eight attention points a software development organizations should take into account aiming to perform the activities of security and performance verification successfully.

You can contribute to the evolution of these moderation factors providing your opinion about them.

Software Verification

Software development is an activity fundamentally developed by humans. So, of course, mistakes will be made. These mistakes result in the insertion of defects in the software. When the users use the software such defects can be instantiated in the form of failures.

In the software development world, there is a family of activities named Software Verification that aims to identify software defects before the software release. Software verification encompasses testing and reviews.

The activities of software verification may target functional requirements or non-functional requirements, such as usability, portability, reliability, security, performance, etc.

Besides, the way such activities are conducted can influence their effectiveness (number of identified defects) and efficiency (number of identified defectsconcerning the used resources).

In this way, it is crucial to identify some influence points of verification activities aiming to improve the effectiveness of them and mitigate the resources waste (e.g., work hours). Such influence points can be seen as Moderation Factors. For instance, configuring an Adequate Verification Environment to perform the activities of software verification is an important point. Therefore, an Adequate Verification Environment is a Moderation Factor.

It is important to note that the lack of an adequate verification environment does not prevent verification. The moderation factor is not a deterrent, but it amplifies or decreases the success of verification activities. For example, if there isn’t a testing environment, then testing activities can be performed in the production environment. Thus, the moderation factor Adequate Verification Environment did not prevent the testing activity to be performed. However, performing the testing in the production environment will decrease the rate of detected defects, and it can still hurt the data of real users.

Therefore, if you want to successfully implement activities of security and performance verification in your organization, you should consider the eight moderation factors presented here.

It is important to note that the moderation factors presented here are specifically related to security and performance verification.

Moderation Factors of Security and Performance Verification

The general idea is that acting to promote the Moderation Factors in your organization makes the activities of security and performance verification more successful.

1 Promote organizational awareness of the importance of security and performance 

Security and performance verification should not be the responsibility of a separate organization department. The global organizational perception of the importance of the security and performance of software systems affects verification activities. Thus, security and performance verification activities require the support of every stakeholder.

2 Plan security and performance verification activities

Security and performance verification should not be performed in insolation by only one team. They require interaction between different teams as well as various skills.

3 Encourage reuse practices

The requirements are the oracle for security and performance verification. Therefore, the lack of requirements prevents the team from a judge if the verification results are correct. Moreover, inaccurate requirements overload other groups (e.g., analysts, architects, and developers) because the verification team must continuously contact them. There are a set of issues brought by the lack of suitable requirements.

4 Use a systematic verification methodology 

The use of suitable support tools is essential in security and performance verification activities because it can decrease the effort of manual activities. Free tools are advisable because the acquisition process is faster, as it involves the technical team only. In the case of adopting proprietary tools, it is necessary to ask the managers for permission, and the price may hinder or impede the buying process.

5 Configure an adequate verification environment 

A suitable environment is essential for security and performance verification. It should encompass both the configurations of the infrastructure responsible for system operation (e.g., application server and database parameters) and the configuration of the system itself (e.g., the data stored on the database while verification activities start).

6 Select suitable support tools 

A methodology supports the verification team knows what should be done at each phase of the verification process. If an adequate methodology is available, the security and performance verification practices can be systematically performed; therefore, they become more efficient. Furthermore, there are some attributes for a proper methodology and elements a methodology should include.

7 Produce clear requirements 

Planning is vital to define what should be done, to know the available resources (e.g., human resources, time, tools) and then establish the way the activities should be performed. However, usually, the security and performance verification is not well planned, leading to the need to reprioritize the verification activities, and consequently to the reduction of their coverage.

8 Keep a cross-functional team

The reuse of knowledge and artifacts, such as functional test cases, brings a set of benefits to security and performance verification. Besides, it also brings benefits to functional verification activities.

Conclusion

The moderation factors of security and performance verification presented here are the findings of a researching encompassing a set of software development organizations. For more details, you can access our technical report or contact me by email vidigal@cos.ufrj.br

8 Fatores para o desenvolvimento de software seguro e com desempenho

Introdução

Fatores de moderação podem ser considerados algo que contribui para um resultado. Este post apresenta 8 fatores de moderação relacionados à verificação de segurança e desempenho de software. Ou seja, são oito pontos que uma organização de desenvolvimento de software deve se atentar para desempenhar as atividades de verificação de desempenho e segurança com sucesso. Com isso, desenvolver software seguro e com melhor desempenho.

Você pode contribuir para a evolução desses fatores fornecendo sua opinião sobre eles aqui!

Verificação de software

O desenvolvimento de software é uma atividade essencialmente desenvolvida por pessoas. Dessa forma, uma das certezas que temos é que, naturalmente, erros serão cometidos. Esses erros acabam inserindo defeitos no software desenvolvido que, ao serem executados, aparecem para os usuários em forma de falhas.

Ao desenvolver um software, existe um conjunto de atividade denominadas Verificação de Software. A verificação de software, que engloba testes e revisões, tem o objetivo de identificar falhas antes que o software seja colocado em produção.

As atividades de verificação podem ser direcionadas para a avaliação dos requisitos funcionais, mas também podem avaliar os requisitos não-funcionais como usabilidade, portabilidade, confiabilidade, segurança, desempenho, etc.

Além disso, a forma como as atividades de verificação são conduzidas podem influenciar sua eficácia (quantidade de defeitos identificados) e eficiência (quantidade de defeitos identificados em relação aos recursos utilizados).

Dessa forma, é preciso identificar alguns pontos que influenciam as atividades de verificação para melhorar a eficácia dessas atividades e prevenir o desperdício de recursos (ex.: mão de obra). Esses pontos de influência, podem ser vistos como Fatores de Moderação. Por exemplo, Configurar um Ambiente Adequado para realizar as atividades de verificação de software é um ponto importante a se considerar. Portanto, um Ambiente Adequado é Fator de Moderação.

Isso não quer dizer que sem um ambiente adequado é impossível realizar a verificação do software. O fator de moderação não é impeditivo, mas amplifica ou diminui o sucesso das atividades de verificação. Por exemplo, na falta de um ambiente de teste adequado, atividades de teste de software podem utilizar o ambiente de produção. Assim, o moderador Ambiente Adequado, não impediu que a atividade de teste fosse executada. Entretanto, a execução dos testes no ambiente de produção vai prejudicar a detecção de falhas e ainda pode danificar dados reais dos usuários.

Portanto, caso queira implementar atividades de verificação de segurança e desempenho em sua organização com sucesso, você deve considerar os 8 fatores de moderação apresentados aqui.

Os fatores de moderação aqui apresentados são relacionados especificamente à verificação de segurança e desempenho.

Fatores de moderação de segurança e desempenho de software

A ideia geral é que agir de forma a promover os Fatores de Moderação em sua organização faz com que atividades de Verificação de Segurança e Desempenham tenham mais sucesso.

1 Promover a consciência organizacional sobre a importância de segurança e desempenho

A verificação de segurança e desempenho não deve ser responsabilidade de um único departamento. A percepção global da importância de segurança e desempenho dos sistemas de softwares desenvolvidos pela organização afeta as atividades de verificação. Assim, as atividades de segurança e desempenho dependem do apoio de todos os stakeholders.

2 Manter uma equipe multidisciplinar

A verificação de segurança e desempenho não deve ser desempenhada de forma isolada por uma única equipe. As atividades de verificação requerem interação entre equipes diferentes bem como diferentes habilidades.

3 Produzir requisitos claros e não ambíguos

Os requisitos são o oráculo para a verificação de segurança e desempenho. Portanto, a falta de requisitos impede a equipe de avaliar se os resultados da verificação estão corretos. Além disso, requisitos imprecisos sobrecarregam outras equipes (ex.: analistas, arquitetos e desenvolvedores), pois a equipe de verificação precisa contatá-los frequentemente. Há um conjunto de questões trazidas pela falta de requisitos inadequados.

4 Possuir ferramentas de apoio adequadas

A utilização de ferramentas adequadas é essencial para as atividades de verificação de segurança e desempenho, pois tendem a diminuir o esforço de atividades manuais. Ferramentas livre são aconselháveis, pois o processo de aquisição é mais rápido por envolver apenas a equipe técnica. No caso da adoção de ferramenta proprietária, é necessário a permissão dos gerentes e o preço pode ser um fator de impedimento.

5 Configurar um ambiente adequado

Um ambiente adequado é essencial para a verificação de segurança e desempenho. Este ambiente deve englobar tanto a configuração da infraestrutura responsável pela operação (parâmetros dos servidores de aplicação e banco de dados) quanto a configuração do próprio sistema (dados armazenados no início da verificação).

6 Utilizar uma metodologia sistemática

Uma metodologia apoia a equipe de verificação a saber o que deve ser feito em cada fase do processo de verificação. Caso uma metodologia adequada esteja disponível, as práticas de verificação de segurança e desempenho podem ser desempenhadas de forma sistemática; portanto, tornando-se mais eficientes. Além disso, existem alguns atributos e elementos que uma boa metodologia deve contemplar.

7 Planejar as atividades de verificação de segurança e desempenho

Planejamento é essencial para definir o que deve ser realizado, conhecer os recursos disponíveis (ex.: recursos humanos, tempo, ferramentas) e então estabelecer a forma como as atividades devem ser desempenhadas. Entretanto, geralmente a verificação de segurança e desempenho não é adequadamente planejada, levando à necessidade de redefinição na prioridade das atividades de verificação e, consequentemente, a redução de sua cobertura.

8 Estimular práticas de reutilização

A reutilização de conhecimento e artefatos, como os casos de teste funcionais, traz benefícios à verificação de segurança e desempenho. Além disso, a verificação funcional também se beneficia da prática de reutilização.

Conclusão

Os fatores de moderação de verificação de segurança e desempenho aqui apresentados são resultado de uma pesquisa que envolveu diversas organizações de desenvolvimento de software. Caso tenha interesse em saber mais informações sobre a pesquisa, veja nosso relatório técnico ou entre em contato através do e-mail vidigal@cos.ufrj.br.
