How can you detect and respond to unauthorized access attempts in Information Security?

Reviewing access policies at regular intervals or on occurrence of material events is absolutely vital to curb the risks arising from inappropriate and/or unauthorised access.

1. Access review begins at the initial stage i.e when a user submits a request and it's Role approver responsibility to check and approve/Reject if the user is authorised to have requested access based on team/Position/Org unit etc.. 2. Monthly UAR such as a IT HPA access check for Business Users, Business Sensitive Access check for IT users will help to identify and remediate before an Audit team marks it as deficiency. 3. Annual/BI Annual UAR and remediations. 4. Business Process documentation of exceptional cases with wider access and quarterly review of such user access. 5. Avoid manual role assignments and in case of exceptional cases, make sure SOD conflicts check before assignment. Assign mitigation control in case of SODconflicts

In Information Security, detecting and responding to unauthorized access attempts is crucial for maintaining the integrity of systems. Employing robust intrusion detection systems (IDS) and intrusion prevention systems (IPS) helps in identifying suspicious activities such as unusual login attempts or unauthorized access to sensitive data. Additionally, implementing multi-factor authentication and regular security audits can further fortify defences, enabling swift response mechanisms like automated alerts and manual intervention to mitigate potential breaches before they escalate.

Implemente sistemas de monitoramento de segurança robustos, como sistemas de detecção de intrusão (IDS) e sistemas de prevenção de intrusão (IPS). Além disso, é importante estabelecer políticas claras de acesso e autenticação, incluindo a utilização de autenticação multifatorial e a revisão regular de permissões de usuário. Ao detectar uma tentativa de acesso não autorizado, é crucial agir rapidamente, bloqueando o acesso, investigando a origem da tentativa e aplicando medidas corretivas para mitigar o impacto e evitar futuras violações de segurança.

In the area of information security, having access policies and correct monitoring is essential for successful threat mitigation. In this context, protecting systems using the principles of least privilege will result in greater control over threats and access releases. Therefore, from the moment any employee enters, it is important to provide visibility of the security guidelines necessary for that environment.

Based on an understanding of the environment, monitoring and alerting solutions are essential to generate visibility of access threats. In this context, the creation of playbooks and use cases can be a key point in adapting a standard alert to a specific action that may occur in your environment.

Tools available in the market today would offer multiple features. It is important for an organisation to understand which tool will work best for them. Once obtained, appropriate SMEs must be engaged to ensure the features of access event monitoring are rightly configured to ensure the access event monitoring objectives are met.

Monitoring logs is very important and it should be ongoing process and you may create alert like when certain condition happen send you special alert like if they have been multiple failure attempts.

To detect and respond to unauthorized access attempts in Information Security, implement robust access controls such as monitoring logs, using intrusion detection systems, implementing strong user authentication methods, applying access control lists, and utilizing security information and event management tools. Additionally, having an incident response plan in place will help you respond quickly and effectively to any unauthorized access attempts.

To detect and respond to unauthorized access attempts in Information Security, it's essential to have robust incident response procedures in place. Regularly monitor access logs and use intrusion detection systems to identify suspicious activity. Implement strong authentication methods and access controls to prevent unauthorized access. When unauthorized access is detected, follow your incident response plan, which should include isolating affected systems, containing the breach, investigating the incident, and implementing corrective actions to prevent future unauthorized access attempts. Regularly review and update your incident response plan to address new threats and vulnerabilities.

In addition to performing an internal audit, an organization should also consider getting an external audit done by an independent external authority to evaluate the maturity of the controls implemented by them in reference to the current trends in the cyber security space. This can definitely help an organization think outside the box to understand the key controls that they can enable to improve their security posture.  Implementing controls with reference to the SOC 2 (System and Organization Controls) framework can definitely be challenging and beneficial for a service provider, as it can even build trust from a customer standpoint for protecting their information assets.

Auditing is a fundamental part of the safe process of any environment, organization or product. Identifying strengths and weaknesses through a macro and micro view is important to create action plans and activity records to always improve the security environment, as well as review access and failures in movements between sectors or in the execution process.

Remain proactive and vigilant; complacency is not an option. Implement multiple layers of detection mechanisms to increase the likelihood of identifying intrusions. A swift response is crucial as it minimizes attacker activity and mitigates the impact of security breaches.

é essencial realizar uma análise forense detalhada para entender a extensão do acesso não autorizado e identificar possíveis danos ou comprometimentos adicionais. Isso pode envolver o isolamento de sistemas afetados, a coleta de evidências digitais e a colaboração com equipes de resposta a incidentes para uma investigação completa. Além disso, é importante implementar medidas de prevenção proativas, como a atualização regular de sistemas e aplicativos, o treinamento de conscientização em segurança para funcionários e a implementação de controles de acesso baseados em função para limitar o acesso privilegiado apenas a usuários autorizados.
