The CIA triad offers a comprehensive framework for information security, encompassing the fundamental goals of safeguarding data confidentiality, integrity, and availability. Incorporating these principles into security protocols enables organizations to mitigate vulnerabilities, meet regulatory standards, and foster confidence among stakeholders. Nevertheless, striking a harmonious equilibrium among these principles poses a formidable task, given that imposing rigorous security protocols to fortify confidentiality and integrity may hinder resource availability. Hence, organizations must meticulously assess their security needs and customize strategies to adeptly counteract the distinct risks and vulnerabilities encountered.

Para melhorar a segurança da informação, aplicar a tríade da CIA envolve iniciativas como criptografar senhas para garantir a confidencialidade, implementar autenticação de dois fatores (2FA) para reforçar tanto a confidencialidade quanto a integridade, e utilizar CAPTCHAs para proteger contra ataques de força bruta, assegurando a disponibilidade dos sistemas. Essas medidas práticas ajudam a proteger dados e sistemas contra acessos não autorizados e garantem que estejam disponíveis para usuários legítimos.

The CIA triad is an important model to follow when it comes to confidentiality, integrity, and availability. Additionally, each one of these factors, has its own security model. To strengthen confidentiality, you can implement the Bell-LaPadula Security Model. To achieve integrity, you can implement the Biba Security Model. The Clark-Wilson Security Model is also used to achieve integrity.

The most important principles of information security include confidentiality, integrity, and availability (CIA). Confidentiality ensures that sensitive information is only accessible to authorized individuals or systems, protecting it from unauthorized access or disclosure. Integrity ensures that data remains accurate, complete, and trustworthy by preventing unauthorized alterations, deletions, or modifications. Availability ensures that information and resources are consistently accessible to authorized users when needed, minimizing downtime and disruptions to operations. Additionally, other essential principles include authentication, authorization, accountability, and resilience.

The most important principles of information security include confidentiality, ensuring that sensitive data is accessible only to authorized users; integrity, maintaining the accuracy and completeness of data by preventing unauthorized modification or deletion; availability, ensuring that information and resources are accessible when needed by authorized users; authentication, verifying the identity of users and systems to prevent unauthorized access; and accountability, holding individuals and entities responsible for their actions within the information system, promoting transparency and traceability.

Além das medidas de segurança mencionadas, integrar proteção contra ataques DDoS, como a oferecida pelo Cloudflare, é uma prática que reforça a estratégia de defesa em profundidade nos projetos. Isso ajuda a salvaguardar a disponibilidade dos sistemas contra tentativas de sobrecarregar a infraestrutura de rede, garantindo que os serviços permaneçam acessíveis mesmo sob ataque.

Para garantir a segurança e a funcionalidade nos meus projetos, implemento o princípio do privilégio mínimo atribuindo diferentes permissões a cada usuário no banco de dados. O sistema, então, controla e exibe apenas as informações relevantes para cada usuário, conforme suas permissões específicas, reduzindo a exposição a potenciais riscos de segurança sem limitar o acesso necessário para realizar suas tarefas.

Na implementação do princípio "Necessidade de Saber", informações sensíveis são restritas a administradores do sistema, enquanto que para funções como o suporte, o acesso é limitado a informações básicas relevantes às suas tarefas, como o status de pedidos.

I would put Security Awareness at the top of this list. Educating your staff on Information Security best practices and how to avoid social engineering scams is by far the best defense against hackers as a large portion of hacks originate from social engineering based scams. Educate your staff on how to avoid these scams and why certain best practices (ie password security, MFA, etc) are necessary and you've put your business on a solid footing. Then, incorporate that same education into your onboarding so new hires receive the same training. Also, implement a program for annual refreshers to keep everyone up to date on the latest prevention techniques. Then, you can also add in technological safeguards, but education should be first.

Learn how to say yes. Just saying no is not security. People ask to do things because they need to do them, to do their job. So you need to find a way to allow them to do their job and to do what they need to do securely. You need to find a way to explain to them why doing exactly what they want to do is insecure. Just saying no because you want to deal with it later, or it's easier to say no than it is to find a way to enable them to be able to accomplish their goal. Leads to Shadow ops. If you think your organization doesn't have Shadow ops or Shadow IT I got a bridge to sell you. Learn how to say, no not that way, let me show you how to do it right, and why you need to do it right.
