What are the best access control practices for IT infrastructure security?

To ensure robust IT infrastructure security, it's essential to implement comprehensive access control practices. This includes adhering to the principle of least privilege, where user access is restricted to the minimum necessary for their role. Role-based access control (RBAC) further enhances security by assigning permissions based on predefined roles. Multi-factor authentication (MFA) adds an extra layer of protection, while regular access reviews help identify and revoke unnecessary permissions. Encrypting sensitive data, maintaining detailed logs, implementing network segmentation, and continuous monitoring round out the approach, ensuring a robust defense against security threats.

Implement the principle of least privilege. ? Use Role-Based Access Control (RBAC). ? Conduct regular access reviews. ? Enforce strong authentication (MFA). ? Use centralized access management. ? Implement segregation of duties (SoD). ? Maintain audit trails and logging. ? Encrypt sensitive data. ? Provide regular security training. ? Establish emergency access procedures.

Acho interessante o gerenciamento de quem pode acessar, o que cada usuário tem permiss?o para fazer e a checagem/rastreabilidade das a??es realizadas pelos usuários no sistema.

ISO 27001 should be the first resource to check out what ACMs are available to you, as most contracts require this standard or better.

The 'need-to-know' policy is a fundamental rule in information security, limiting access to sensitive information to only those who need it, and reducing the risk of issues such as data breaches. While it may appear to conflict with an open culture that prioritises transparency and teamwork, both can work together effectively. This balance is achieved by specifying which information is public and which is restricted, defining data owners clearly, educating employees about the importance of security, implementing strong access controls, and promoting a culture where everyone takes part in ensuring security.

While it is important to secure data in transit, it has become more important to secure data at rest. Secure your end points, enable encryption at computing layer, storage and put controls like DLP.

Very critical to monitor and regular audits of access controls. Identification of unauthorized access is critical to know in advance or at least on real time basis. With high attrition in IT sector, it becomes more important to have controlled on-boarding and de-boarding process.

Awareness across organisation is very important. knowing data security is not only important to tech staff, however every user in the organisation including senior leadership team.

Oh yes , security is a partnership approach . It need both hands to clap !!! Normally people think that security group or IT group is responsible for the security but that not true. Security is everyone's business, it's more like protecting yourself from infections , if you get infected then whole family is at risk.

Threat defense knowledge is more necessary and important for end users. Only a tech guy is not sufficient to prevent any unwanted attack. Threat defense knowledge is mandatory for both parties. Users are the first layer to threats, so along with tech guys, users have to be more aware and knowledgeable about threats.
