A USB port is a physical door into every endpoint in your organization. Unlike network-based attack vectors that can be monitored, filtered, and logged at scale, USB access happens at the device level, directly on the endpoint, often in seconds, and is invisible to network controls entirely.
Email authentication is the set of technical controls that verify whether an email message actually originated from the domain it claims to represent.
The browser is the most exposed application on every endpoint in a modern organization. It is the primary interface through which users access email, SaaS applications, collaboration tools, external web content, and cloud resources.
An Intrusion Detection System (IDS) monitors network traffic or host activity for signs of malicious behavior and generates alerts when suspicious patterns are detected.
Windows security configuration is the discipline of applying specific operating system settings, policy controls, and security features to Windows endpoints and servers to reduce their attack surface, limit adversary capability, and maintain a documented, auditable security baseline.
Network Access Control (NAC) is a security framework that enforces policy-based decisions about which devices are permitted to connect to a network and what those devices can access once connected.
Linux security hardening is the systematic application of configuration changes, access controls, kernel parameters, and monitoring capabilities to a Linux system to reduce its attack surface and constrain what an adversary can do after gaining initial access.
A Distributed Denial of Service (DDoS) attack is an attempt to make a target system, service, or network unavailable by overwhelming it with traffic or resource requests from multiple sources simultaneously.
CIS Benchmarks are configuration guides published by the Center for Internet Security (CIS), a nonprofit organization that convenes security professionals across government, industry, and academia to establish consensus-based standards for secure system configuration.
