SIEM products pull together the information that your security staff needs to identify and respond to threats. Explanation: An IPS is deployed in inline mode and will not allow malicious traffic to enter the internal network without first analyzing it. Remote servers will see only a connection from the proxy server, not from the individual clients. A stateful firewall provides more stringent control over security than a packet filtering firewall. 116. What security countermeasure is effective for preventing CAM table overflow attacks? 103.

Question 1 Consider these statements and state which are true. In addition to protecting assets and the integrity of data from external exploits, network security can also manage network traffic more efficiently, enhance network performance and ensure secure data sharing between employees and data sources. The internal hosts of the two networks have no knowledge of the VPN. SuperScan is a Microsoft port scanning software that detects open TCP and UDP ports on systems. Security features that control that can access resources in the OS. DH (Diffie-Hellman) is an algorithm used for key exchange. Explanation: With most modern algorithms, successful decryption requires knowledge of the appropriate cryptographic keys. Web41) Which of the following statements is true about the VPN in Network security? RADIUS offers the expedited service and more comprehensive accounting desired by remote-access providers but provides lower security and less potential for customization than TACACS+. R1 will open a separate connection to the TACACS+ server for each user authentication session. Refer to the exhibit. command whereas a router uses the help command to receive help on a brief description and the syntax of a command. Explanation: CIA refers to Confidentiality, Integrity, and Availability that are also considered as the CIA triad. ***A network security policy is a document that describes the rules governing access to a company's information resources Which of the following A. UserID Traffic that is originating from the public network is usually blocked when traveling to the DMZ network. Explanation: IPS signatures have three distinctive attributes: 37. Port security gives an administrator the ability to manually specify what MAC addresses should be seen on given switch ports. Network security combines multiple layers of defenses at the edge and in the network. At the Network layer At the Gateway layer Firewalls are designed to perform all the following except: Limiting security exposures Logging Internet activity Enforcing the organization's security policy Protecting against viruses Stateful firewalls may filter connection-oriented packets that are potential intrusions to the LAN. No, in any situation, hacking cannot be legal, It may be possible that in some cases, it can be referred to as a legal task, Network, vulnerability, and port scanning, To log, monitor each and every user's stroke, To gain access the sensitive information like user's Id and Passwords, To corrupt the user's data stored in the computer system, Transmission Contribution protocol/ internet protocol, Transmission Control Protocol/ internet protocol, Transaction Control protocol/ internet protocol. (Choose two.). 29. 21. 110. authenticator-The interface acts only as an authenticator and does not respond to any messages meant for a supplicant. Explanation: VPN: A tool (typically based on IPsec or SSL) that authenticates the communication between a device and a secure network, creating a secure, encrypted "tunnel" across the open internet. Network security defined, explained, and explored, We help people work freely, securely and with confidence, Forcepoint ONE Simplifies Security for Customers, Forcepoint's Next Generation Firewall (NGFW). The TACACS+ server only accepts one successful try for a user to authenticate with it. What technology has a function of using trusted third-party protocols to issue credentials that are accepted as an authoritative identity? Production traffic shares the network with management traffic. 117. Add an association of the ACL outbound on the same interface. It copies the traffic patterns and analyzes them offline, thus it cannot stop the attack immediately and it relies on another device to take further actions once it detects an attack. 33. Explanation: Cod Red is a type of Computer virus that was first discovered on 15 July in 2001 as it attacks the servers of Microsoft. (Not all options are used.

Many home users share two common misconceptions about the security of their networks: Home Network Security | A network administrator is configuring DAI on a switch. While it is a good idea to configure a banner to display legal information for connecting users, it is not required to enable SSH.. Prevent spam emails from reaching endpoints. (Not all options are used.). (Choose two. ASA uses the ? B. D. All of the above. They typically cause damages to the systems by consuming the bandwidths and overloading the servers. A virus can be used to deliver advertisements without user consent, whereas a worm cannot. Cybercriminals are increasingly targeting mobile devices and apps. The Email Security Tools can handle several types of attacks, such as the incoming attacks, and protect the outbound messages containing sensitive data/information as well. The neighbor advertisements from the ISP router are implicitly permitted by the implicit permit icmp any any nd-na statement at the end of all IPv6 ACLs. Failures on the production network may not be communicated to the OOB network administrator because the OOB management network may not be affected. 23. (Choose two.). It requires using a VPN client on the host PC. 101. The IOS do command is not required or recognized. it is usually used by users while hacking the Wi-Fi-networks or finding vulnerabilities in the network to capture or monitor the data packets traveling in the network. A technician is to document the current configurations of all network devices in a college, including those in off-site buildings. In some cases where the firewall detects any suspicious data packet, it immediately burns or terminates that data packet. When the CLI is used to configure an ISR for a site-to-site VPN connection, which two items must be specified to enable a crypto map policy? 20) To protect the computer system against the hacker and different kind of viruses, one must always keep _________ on in the computer system. 123. 22. 88.

Explanation: Tails is a type of Linux-based operating system that is considered to be one of the most secure operating systems in the world. 126. Traffic from the Internet can access both the DMZ and the LAN. When just a few minutes of downtime can cause widespread disruption and massive damage to an organization's bottom line and reputation, it is essential that these protection measures are in place. Network access control (NAC) can be set at the most granular level. Set up an authentication server to handle incoming connection requests. Using an out-of-band communication channel (OOB) either requires physical access to the file server or, if done through the internet, does not necessarily encrypt the communication. For every inbound ACL placed on an interface, there should be a matching outbound ACL. What are two methods to maintain certificate revocation status? 135. Explanation: The components of the login block-for 150 attempts 4 within 90 command are as follows:The expression block-for 150 is the time in seconds that logins will be blocked.The expression attempts 4 is the number of failed attempts that will trigger the blocking of login requests.The expression within 90 is the time in seconds in which the 4 failed attempts must occur. Syslog does not authenticate or encrypt messages. What are two differences between stateful and packet filtering firewalls? Place standard ACLs close to the source IP address of the traffic. The public zone would include the interfaces that connect to an external (outside the business) interface. What job would the student be doing as a cryptanalyst? In which some top-level accessions were hidden in the big wooden horse-like structure and given to the enemy as a gift. Explanation: DNS stands for the Domain name system; the main work of a DNS is to translate the Domain name into an IP address that is understandable to the computers. It is a device installed at the boundary of a company to prevent unauthorized physical access. Explanation: The IPsec framework uses various protocols and algorithms to provide data confidentiality, data integrity, authentication, and secure key exchange. 34.
