Explanation: The example given in the above question refers to the least privileges principle of cyber security. Explanation: The reason to configure OSPF authentication is to mitigate against routing protocol attacks like redirection of data traffic to an insecure link, and redirection of data traffic to discard it. For example, users working from home would typically connect to the organization's network over a VPN. if you allow him access to the resource, this is known as implementing what? It is a type of device that helps to ensure that communication between a device and a network is secure. What is the function of a hub-and-spoke WAN topology? 115. You have been asked to determine what services are accessible on your network so you can close those that are not necessary. 114. The code is authentic and is actually sourced by the publisher. Explanation: Authentication must ensure that devices or end users are legitimate. It requires using a VPN client on the host PC. What service provides this type of guarantee? ), Explanation: There are many differences between a stateless and stateful firewall.Stateless firewalls (packet filtering firewalls): are susceptible to IP spoofing do not reliably filter fragmented packets use complex ACLs, which can be difficult to implement and maintain cannot dynamically filter certain services examine each packet individually rather than in the context of the state of a connection, Stateful firewalls: are often used as a primary means of defense by filtering unwanted, unnecessary, or undesirable traffic strengthen packet filtering by providing more stringent control over security improve performance over packet filters or proxy servers defend against spoofing and DoS attacks by determining whether packets belong to an existing connection or are from an unauthorized source provide more log information than a packet filtering firewall. Which of the following is NOT a guideline of a security policy? A DoS attack ties up network bandwidth or services, rendering resources useless to legitimate users. The code has not been modified since it left the software publisher. (Choose two. Commands cannot be added directly to a superview but rather must be added to a CLI view and the CLI view added to the superview. So the correct answer will be 1970.
