Explanation: The permit 192.168.10.0 0.0.0.127 command ignores bit positions 1 through 7, which means that addresses 192.168.10.0 through 192.168.10.127 are allowed through. We will update answers for you in the shortest time. 135. Virtual private networks (VPNs) create a connection to the network from another endpoint or site. Explanation: The example given in the above question refers to the least privileges principle of cyber security. Network security is the practice of preventing and protecting against unauthorized intrusion into corporate networks. ), * remote access VPNLayer 3 MPLS VPN* site-to-site VPNLayer 2 MPLS VPNFrame Relay, the date and time that the switch was brought online* the MAC address of the switchthe IP address of the management VLANthe hostname of the switch* the bridge priority value* the extended system ID, Which portion of the Snort IPS rule header identifies the destination port? For example, Forcepoint's Next Generation Firewall (NGFW) offers seamless and centrally managed control of network traffic, whether it is physical, virtual or in the cloud. It can also be considered as a device installed at the boundary of an incorporate to protect form unauthorized access. B. CLI views have passwords, but superviews do not have passwords. The code has not been modified since it left the software publisher. What type of NAT is used? Describe the purpose of a protocol analyzer and how an attacker could use one to compromise your network. Which facet of securing access to network data makes data unusable to anyone except authorized users? In short, we can also say that it is the first line of defense of the system to avoid several kinds of viruses. 26. Authorization is concerned with allowing and disallowing authenticated users access to certain areas and programs on the network. Explanation: Application security, operational security, network security all are the main and unforgettable elements of Cyber Security. Therefore the correct answer is D. 23) Which of the following are famous and common cyber-attacks used by hackers to infiltrate the user's system? (Choose two.). Frames from PC1 will be forwarded to its destination, and a log entry will be created.
