    SafeLine

    SafeLine

    Serve as a reverse proxy to protect your web services from attacks

    SafeLine is a self-hosted WAF(Web Application Firewall) to protect your web apps from attacks and exploits. A web application firewall helps protect web apps by filtering and monitoring HTTP traffic between a web application and the Internet. It typically protects web apps from attacks such as SQL injection, XSS, code injection, os command injection, CRLF injection, LDAP injection, XPath injection, RCE, XXE, SSRF, path traversal, backdoor, brute force, HTTP-flood, bot abuse, among others. By deploying a WAF in front of a web application, a shield is placed between the web application and the Internet. While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server. A WAF protects your web apps by filtering, monitoring, and blocking any malicious HTTP/S traffic traveling to the web application.

    Naeon

    Naeon

    The safest way to store private data in untrusted (cloud) environments

    Naeon is a data encryption and sharding method designed to secure data in potentially untrusted off-site storage locations. It uses AES-256 encryption with a randomly generated passphrase, followed by obfuscation techniques to make the encrypted file unidentifiable. The data is then sharded into one private chunk containing the encryption key and part of the data, and multiple public chunks. Each chunk is renamed using its SHA-512 hash, and all chunks are timestamped equally. A filename conversion table is created to restore the concatenation order during a restore. The method aims to guarantee confidentiality, integrity, and availability of data, regardless of the trustworthiness of the chosen storage environment, while protecting against data breaches and unauthorized access. Threshold Key Sharing further enhances security and resilience by splitting the private key into parts requiring cooperation from multiple parties for reconstruction, thereby minimizing single points of failure.
