Information security management systems and risk mitigation

ISO 27001 and information security management

ISO 27001 is an international standard that outlines the requirements for an information security management system (ISMS). It helps organizations ensure the confidentiality, integrity, and availability of their information assets by establishing and maintaining appropriate safeguards.

One of the key aspects of ISO 27001 is its focus on risk management. The standard provides guidance on how to identify, assess, and treat risks to the security of information assets. This includes risks related to international operations, such as cross-border data transfers and the potential for different legal and regulatory frameworks to apply in different countries.

To use ISO 27001 effectively in international operations, organizations need to take into account the specific risks and challenges that they face in these contexts. This may involve adapting their ISMS to address the specific requirements of different countries or regions, or implementing additional safeguards to protect against the unique risks associated with international operations.

In addition, organizations operating internationally may need to consider the requirements of other relevant standards and regulations, such as the EU’s General Data Protection Regulation (GDPR).

How to manage international risks when outsourcing IT services

In order to mitigate risk, there are several key considerations that a company outsourcing IT services needs to take into account with regard to information security management systems (ISMS):

  1. Service level agreements: It is important to ensure that the IT service provider has clear and appropriate service level agreements in place that outline the security measures they will put in place to protect the company’s information assets. These agreements should cover areas such as access controls, data backup and recovery, and incident response.
  2. Data protection: The IT service provider should have robust data protection measures in place to ensure the confidentiality, integrity, and availability of the company’s data. This may include measures such as encryption, secure data storage, and data backup and recovery.
  3. Compliance: The IT service provider should be able to demonstrate compliance with relevant information security standards and regulations, such as ISO 27001 or the EU’s General Data Protection Regulation (GDPR).
  4. Risk assessment: The IT service provider should conduct regular risk assessments to identify and address potential vulnerabilities and threats to the company’s information assets.
  5. Communication: The company outsourcing IT services should establish clear lines of communication with the IT service provider to ensure that any concerns or issues related to information security are promptly addressed.

Access controls and risk management

Access controls is an effective risk management tool that should be a significant pillar in all information security management systems. Access controls as a risk mitigation include:

  1. User access controls: These controls are designed to ensure that only authorized individuals are able to access the company’s information systems and data. This may involve using measures such as passwords, biometric authentication, or security tokens.
  2. Network access controls: These controls are designed to protect the company’s network from unauthorized access, such as by using firewalls and intrusion detection systems.
  3. Data access controls: These controls are designed to ensure that only authorized individuals are able to access specific data sets or resources. This may involve using measures such as data encryption, access control lists, or role-based access controls.
  4. Physical access controls: These controls are designed to protect the company’s physical assets, such as servers and data centers, from unauthorized access. This may involve using measures such as security cameras, access cards, or security guards.

In addition to these controls, companies should also ensure that the IT service provider has robust policies and procedures in place to manage access to the company’s information systems and data. This may involve regular reviews of access permissions and the implementation of strict processes for granting and revoking access as needed.

Requesting robust access controls is not the same as ensuring they are in place, and like all risk management activities, auditing and compliance is important.

There are several steps you can take to audit the data access controls of a subcontractor:

  1. Review the subcontractor’s data access policies and procedures: Make sure the subcontractor has appropriate policies and procedures in place to control access to sensitive data.
  2. Conduct an on-site audit: Visit the subcontractor’s facility and assess the physical security measures in place to protect data. This may include reviewing access control systems, security cameras, and other measures.
  3. Review the subcontractor’s technical controls: Check to see whether the subcontractor has implemented appropriate technical controls to prevent unauthorized access to data. This may include access controls, data encryption, and other security measures.
  4. Test the subcontractor’s data access controls: Conduct testing to ensure that the subcontractor’s data access controls are effective. This may include attempting to access data without proper authorization or attempting to bypass security measures.
  5. Review the subcontractor’s training and awareness program: Make sure the subcontractor has a robust training and awareness program in place to educate employees on data security and access controls.

It’s important to remember that auditing data access controls is just one aspect of ensuring data security. It’s also important to regularly review and update policies and procedures, conduct ongoing training, and monitor for potential security breaches.
