Prober

可重现地检查网络假设 该项目使用 Ansible 生成 BATS 测试文件，以验证关于网络基础设施的安全假设。测试从探测机器（"探测节点 "）运行，Prober 部署在这些节点上。 此工具旨在对自有网络进行可重现的自动化测试。它支持多个探测节点同时运行测试，每个节点对被测网络有不同的视角——例如，来自 外部 区域的视角、来自 内部 区域的视角，以及来自 DMZ 内部的视角。 使用 Prober 探测未经授权的网络可能是违法的。 要求 在用于将测试部署到探测节点的 Ansible 主控节点上： ansible（当然！） python-netaddr（在 GNU/Linux 上）/...

Explainable PQC: A Layered Interpretive Framework for Post-Quantum Cryptographic Security Assumptions

This paper studies how post-quantum cryptographic PQC security assumptions can be represented and communicated through a structured, layered framework that is useful for technical interpretation but does not replace formal cryptographic proofs. We propose "Explainable PQC,'' an interdisciplinary...

Issue Overview: Applications and libraries which misuse the ServerConfig.PublicKeyCallback callback may be susceptible to an authorization bypass. The documentation for ServerConfig.PublicKeyCallback says that "A call to this function does not guarantee that the key offered is in fact used to...

Zero Trust and the Case for Application Microsegmentation

Data breaches have become incessant. Recently, a very popular airline sevices company revealed a suspected breach involving customer credit card information. Even more recently, a hospital in Indiana reported that a virus had infected some of its systems that caused the hospital to be placed on...

Drawing Outside the Box: Precision Issues in Graphic Libraries

By Mark Brand and Ivan Fratric, Google Project Zero In this blog post, we are going to write about a seldom seen vulnerability class that typically affects graphic libraries though it can also occur in other types of software. The root cause of such issues is using limited precision arithmetic in...

CVE-2018-1113

setup before version 2.11.4-1.fc28 in Fedora and Red Hat Enterprise Linux added /sbin/nologin and /usr/sbin/nologin to /etc/shells. This violates security assumptions made by pamshells and some daemons which allow access based on a user's shell being listed in /etc/shells. Under some circumstance...
