The WPS push button (center, blue) on a wireless router showing the symbol defined by the Wi-Fi Alliance for this function. Wi-Fi Protected Setup (WPS), originally Wi-Fi Simple Config, is a network security standard to create a secure wireless home network.
A more serious security flaw was revealed in December 2011 by Stefan Viehböck that affects wireless routers with the Wi-Fi Protected Setup (WPS) feature, regardless of which encryption method they use. Most recent models have this feature and enable it by default.
2) Rename your network (SSID): The default network name, or SSID, often includes the router’s brand or model, making it easier for hackers to identify vulnerabilities. Rename your network to ...
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
Network access control (NAC) is an approach to computer security that attempts to unify endpoint security technology (such as antivirus, host intrusion prevention, and vulnerability assessment), user or system authentication and network security enforcement.
It is then encapsulated into a new IP packet with a new IP header. Tunnel mode is used to create virtual private networks for network-to-network communications (e.g. between routers to link sites), host-to-network communications (e.g. remote user access) and host-to-host communications (e.g. private chat). [32] Tunnel mode supports NAT traversal.
In a network injection attack, a hacker can make use of access points that are exposed to non-filtered network traffic, specifically broadcasting network traffic such as “Spanning Tree” (802.1D), OSPF, RIP, and HSRP. The hacker injects bogus networking re-configuration commands that affect routers, switches, and intelligent hubs.
US officials are investigating potential national security risks tied to a telecom company founded in China whose internet routers are used by millions, multiple sources familiar with the matter ...
