Instant messaging (IM) has become a popular communication method in many organizations. However, using a public instant messaging solution can introduce risks, including the risk of data leakage. To mitigate this risk, several measures should be in place.
An access control list (ACL) is a security mechanism that controls access to network resources based on a set of rules. An ACL can be used to restrict access to the instant messaging service, such as allowing only authorized users to access the service. An ACL can also be used to restrict access to certain features of the instant messaging service, such as file transfers or screen sharing. This helps to prevent unauthorized access and data leakage.
An acceptable usage policy (AUP) is a set of rules and guidelines that specify how an organization's computing resources can be used. An AUP should include guidelines for the appropriate use of instant messaging and the type of data that can be shared through instant messaging. An AUP can also define the consequences of violating the policy, such as disciplinary action or termination. By setting clear guidelines, an AUP helps to prevent data leakage and other security incidents.
An intrusion detection system (IDS) is a security mechanism that monitors network traffic for suspicious activity. An IDS can be used to detect attempts to access the instant messaging service from unauthorized devices or locations. An IDS can also be used to detect attempts to exfiltrate data through instant messaging. By detecting and alerting on suspicious activity, an IDS can help prevent data leakage.
A data extraction tool is a software tool that can be used to extract data from the instant messaging service. A data extraction tool can be used to monitor instant messaging conversations and extract data that violates the organization's policies. By monitoring and extracting data, a data extraction tool helps to prevent data leakage.
Out of the given options, the most appropriate measure to mitigate data leakage risk is an acceptable usage policy (B). An AUP sets clear guidelines for the appropriate use of instant messaging and the type of data that can be shared through instant messaging. However, all the other measures - ACL (A), IDS (C), and data extraction tool (D) - can also be useful in mitigating data leakage risk when implemented properly.
