Which of the following can be used to mitigate attacks from high-risk regions?

IP geolocation allows organizations to identify the geographical location of an IP address. By knowing the origin of network traffic, an organization can implement security policies to block or restrict access from high-risk regions, thereby mitigating potential attacks. Obfuscation aims to make code or data harder to understand but doesn't prevent access based on location. Data sovereignty refers to laws governing data within a country's borders and isn't a direct mitigation technique for attacks from specific regions. Encryption protects data confidentiality and integrity but doesn't prevent traffic from reaching the network based on its origin.
