Explanation: An IPS is deployed in inline mode and will not allow malicious traffic to enter the internal network without first analyzing it. Explanation: The IKE protocol executes in two phases. Network Security (Version 1) Network Security 1.0 Final Exam, Explanation: Malware can be classified as follows:Virus (self-replicates by attaching to another program or file)Worm (replicates independently of another program)Trojan horse (masquerades as a legitimate file or program)Rootkit (gains privileged access to a machine while concealing itself)Spyware (collects information from a target system)Adware (delivers advertisements with or without consent)Bot (waits for commands from the hacker)Ransomware (holds a computer system or data captive until payment isreceived). 46.

Traffic from the Internet and DMZ can access the LAN. Which two features are included by both TACACS+ and RADIUS protocols? It is a device installed at the boundary of a company to prevent unauthorized physical access. Filtering unwanted traffic before it enters low-bandwidth links preserves bandwidth and supports network functionality. D. Verification. Which protocol is an IETF standard that defines the PKI digital certificate format? It is an important source of the alert data that is indexed in the Sguil analysis tool. With ZPF, the router will allow packets unless they are explicitly blocked. What is a difference between a DMZ and an extranet? Which protocol works by establishing an association between two communicating devices and can use a preshared key for authentication? Which of the following are the solutions to network security? A security policy should clearly state the desired rules, even if they cannot be enforced. Because in-band management runs over the production network, secure tunnels or VPNs may be needed. Which type of attack is mitigated by using this configuration? Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees. Inspected traffic returning from the DMZ or public network to the private network is permitted. PC1 has a different MAC address and when attached will cause the port to shut down (the default action), a log message to be automatically created, and the violation counter to increment. 45) Which of the following malware's type allows the attacker to access the administrative controls and enables his/or her to do almost anything he wants to do with the infected computers. Which statement is a feature of HMAC? 61. 83. The role of root user does not exist in privilege levels. 141. What function is performed by the class maps configuration object in the Cisco modular policy framework? What is true about VPN in Network security methods? You can block noncompliant endpoint devices or give them only limited access. Add an association of the ACL outbound on the same interface. C. A user account enables a user to sign in to a network or computer. What will be displayed in the output of the show running-config object command after the exhibited configuration commands are entered on an ASA 5506-X? B. Attackers use personal information and social engineering tactics to build sophisticated phishing campaigns to deceive recipients and send them to sites serving up malware. How to find: Press Ctrl + F in the browser and fill in whatever wording is in the question to find that question/answer. (Choose three.). The security policy in a company specifies that employee workstations can initiate HTTP and HTTPS connections to outside websites and the return traffic is allowed. command whereas a router uses the help command to receive help on a brief description and the syntax of a command. Traffic from the Internet can access both the DMZ and the LAN. Features of CHAP: plaintext, memorized token. Which two steps are required before SSH can be enabled on a Cisco router? Each building block performs a specific securty function via specific protocols. Give the router a host name and domain name. B. client_hello AAA is not required to set privilege levels, but is required in order to create role-based views. Port security gives an administrator the ability to manually specify what MAC addresses should be seen on given switch ports. 54) Why are the factors like Confidentiality, Integrity, Availability, and Authenticity considered as the fundamentals?
