Once you've identified your goals, compare the features and functions of different network security audit tools. Look for tools that offer comprehensive capabilities to address your specific needs. Consider factors such as the ability to conduct scans for known vulnerabilities, perform network mapping, analyze traffic patterns, and detect intrusions. Assess whether the tools support automation, integration with other security solutions, and reporting functionalities to streamline the audit process.

Avaliar a usabilidade e confiabilidade de um modelo de avaliação multicritério para tomar decisões sobre riscos envolve entender seu funcionamento, validar critérios, garantir transparência, realizar testes e validações, avaliar respostas a mudanças nos dados, solicitar feedback dos usuários, comparar com outros métodos e realizar atualizações contínuas. Essas etapas permitem determinar a eficácia e utilidade do modelo, possibilitando ajustes para melhorias para em seguida tomar uma decisão.

Choose tools that integrate well with your existing network and security infrastructure. Look for tools that can seamlessly integrate with your SIEM (Security Information and Event Management) system, firewalls, intrusion detection/prevention systems, and other security technologies.

Verifique a usabilidade da ferramenta, considerando fatores como facilidade de instalação, configuração e uso. Além disso, avalie a confiabilidade da ferramenta em termos de precisão na detecção de ameaças e na geração de relatórios. Avaliações de usuários e revisões independentes podem ser úteis nesse aspecto.

Usability and reliability are critical factors to consider when choosing network security audit tools. Opt for tools that are user-friendly and intuitive, allowing your team to efficiently perform audits without extensive training or technical expertise. Additionally, assess the reliability of the tools by researching user reviews, evaluating vendor reputation, and testing the tools in a controlled environment. Choose tools that are known for their stability, accuracy, and effectiveness in identifying security vulnerabilities and threats.

Analise os custos associados à aquisição, implementação e manutenção da ferramenta em relação aos benefícios que ela oferece. Considere não apenas o custo inicial, mas também os custos contínuos, como taxas de licenciamento, suporte técnico e custos de treinamento da equipe. Pondere esses custos em relação aos benefícios em termos de segurança e eficácia da auditoria.

Finally, consider the costs and benefits associated with each network security audit tool. Evaluate the pricing structure, licensing model, and any additional fees or hidden costs. Determine whether the benefits offered by the tools justify the investment, taking into account factors such as improved security posture, reduced risk of breaches, and compliance with regulatory requirements. It's essential to strike a balance between cost-effectiveness and the value delivered by the tools to ensure you're making the best decision for your organization.

There are different types of network security audit tools available both open source and commercial. - Open source tools to monitor your IT infrastructure such as NMAP, OpenVAS, Wireshark, Snort IDS etc,. - Commercial tools will be more effective than the open source tools. - Continuous monitor of network traffic to identify the suspicious activity. - Regularly Scan and test the vulnerability. - Have a NOC team to maintain the continuous IT infrastructure operations. - Schedule a report on different threshold.

Audit is based on a boundary or perimeter of your organizations network, sub-networks or segments. You get to see and count or control the assets based on this. And always make sure that, an active probe or query based network audit is not recommended over an organization's factory or production network as it may badly affect Industrial Control Systems. Certain specific tools are required for Industrial Control Systems. As explained in others comments. Also affordability to use on a continuous basis or only once during the initial infra installation is another choice for the organizations stakeholders.

How to select the best tool for a network security audit: 1. You need to ask the question: what’s the goal? What are your expectations 2. Find a tool that can easily integrate and is compatible with your existing infrastructure 3. Evaluate the cost and implementation of the tool you intend to use 4. Does the tool require a specialized person to use it? 5. Can you easily get updated and newer versions of the tool ? 6. How easy is it to document and assess findings with the tool? All these are questions to be asked to filter and select the most compatible security tool for your business or infrastructure

1. Some tools may require specialized training or certifications, so choose tools that align with team's capabilities or provide training resources. 2. Choose tools that are compatible with network infrastructure and can effectively assess the relevant systems and technologies. 3. Look for tools that are regularly updated, well-documented, and have active support communities. 4.
