# Security Considerations The Ethernity NODE runs tasks that are requested through the blockchain smart contract. This allows anybody to run their own software freely as long as it can be bundled inside a docker container. In order to prevent abuse, the node restricts by default all outgoing connectivity of the full virtualization layer. Only to the required services are permitted: blockchain RPC, ipfs node, docker registry. Further restrictions can be applied by the node operator by updating the source code which is licensed AGLP v3. Additional restrictions can include: running tasks requested only by a set of wallet addresses or running tasks containing only desired docker images. Node operators are responsible for maintaining and enforcing their own set of rules. Running a node requires generating two keypairs that represent the identity of your node and you are fully responsible to keep it safe. Do not share this information, or store it unencrypted outside the node configuration. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ethernity.cloud/ethernity-node-quickstart/security.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
