2024年12月4日 · Disable Secure Shell (SSH) version 1. Ensure only SSH version 2.0 is used with the following cryptographic considerations [2]. For more information on acceptable algorithms, see NSA’s Network Infrastructure Security Guide. Configure with minimally a 3072-bit RSA key. Configure with minimally a 4096 Diffie-Hellman key size (group 16).
bypass network monitoring and security controls and may result in data loss or provide an unsecured network entry point for an attacker. • Unauthorized Association – an AP-to-AP association that can violate the security perimeter of the network. • Ad hoc Connections – a peer-to-peer network connection that can violate the security
Demilitarized Zone (DMZ): In networking, a DMZ is a physical or logical subnet that separates a local area network from other untrusted networks. Since 2015, the Cybersecurity and Infrastructure Security Agency identified boundary protection as the most prevalent discovery in network security architecture assessments across multiple industries.

Securing Network Infrastructure Devices - CISA
4 天之前 · Proper network segmentation is an effective security mechanism to prevent an intruder from propagating exploits or laterally moving around an internal network. On a poorly segmented network, intruders are able to extend their impact to control critical devices or gain access to sensitive data and intellectual property.
