"Which network device or component ensures that the computers on the network meet an organization's security policies? Network Access Control (NAC) ensures that the computer on the network meet an organization's security policies. 24. TACACS+ supports separation of authentication and authorization processes, while RADIUS combines authentication and authorization as one process. It copies traffic that passes through a switch interface and sends the data directly to a syslog or SNMP server for analysis. NOTE: If you have the new question on this test, please comment Question and Multiple-Choice list in form below this article.

Explanation: Reaper is considered as the world's first antivirus program or software as it can detect the copies of a Creeper (the world's first man-made computer virus) and could delete it as well. The level of access of employees when connecting to the corporate network must be defined. The Subscriber Rule Set also provides the fastest access to updated signatures in response to a security incident or the proactive discovery of a new threat. A. The Cybersecurity and Infrastructure Security Agency (CISA) encourages users and network administrators to implement the following recommendations to better secure their network infrastructure: Segment and segregate networks and functions. B. It is a type of network security-enhancing tool that can be either a software program or a hardware device. Refer to the exhibit.
