C.block malicious software that is too new to be found in virus definitions. D.stops infected files from being downloaded via websites.

C atrax 1 month, 2 weeks ago Zero trust is based on the idea that perimeter security is unlikely to be completely robust. On a modern network, there are just too many opportunities for traffic to escape monitoring/filtering by perimeter devices. Zero trust uses systems such as continuous authentication and conditional access to mitigate privilege escalation and account compromise by threat actors. Another zero-trust technique is to apply microsegmentation. Microsegmentation is a security process that is capable of applying policies to a single node, as though it was in a zone of its own. upvoted 2 times f0rsaken 1 month, 2 weeks ago isn't that supposed to be "Zero Day"? upvoted 1 times Squinton 3 weeks, 6 days ago That's what I'm thinking.

#32 Topic 1 Which of the following is the physical topology for an Ethernet LAN? A.Bus B.Ring C.Mesh D.Star

D atrax 1 month, 2 weeks ago In a star topology, each endpoint node is connected to a central forwarding node, such as a hub, switch, or router. The central node mediates communications between the endpoints. The star topology is the most widely used physical topology. For example, a typical SOHO network is based around a single Internet router appliance that clients can connect to with a cable or wirelessly. The star topology is easy to reconfigure and easy to troubleshoot because all data goes through a central point, which can be used to monitor and manage the network. Faults are automatically isolated to the media, node (network card), or the hub, switch, or router at the center of the star. upvoted 1 times f0rsaken 1 month, 2 weeks ago What is this??
