What tool is available through the Cisco IOS CLI to initiate security audits and to make recommended configuration changes with or without administrator input? Explanation: PVLANs are used to provide Layer 2 isolation between ports within the same broadcast domain. Explanation: DEFCON is one of the most popular and largest Hacker's as well as the security consultant's conference. SIEM is used to provide real-time reporting of security events on the network. WebWhat is a network security policy? Firewalls. For this reason, there are many network security management tools and applications in use today that address individual threats and exploits and also regulatory non-compliance. Cisco IOS routers utilize both named and numbered ACLs and Cisco ASA devices utilize only numbered ACLs. 44. 96. Detection 101. 4 or more drinks on an occasion, 3 or more times during a two-week period for females Explanation: In terms of Email Security, phishing is one of the standard methods that are used by Hackers to gain access to a network. What algorithm is being used to provide public key exchange? In computer networks, it can be defined as an authentication scheme that avoids the transfer of unencrypted passwords over the network. Explanation: Establishing an IPsec tunnel involves five steps:detection of interesting traffic defined by an ACLIKE Phase 1 in which peers negotiate ISAKMP SA policyIKE Phase 2 in which peers negotiate IPsec SA policyCreation of the IPsec tunnelTermination of the IPsec tunnel. Generate a set of secret keys to be used for encryption and decryption. Tracking the connection allows only return traffic to be permitted through the firewall in the opposite direction. a. Use statistical analysis to eliminate the most common encryption keys. 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. Which of the following is NOT a guideline of a security policy? This process is network access control (NAC). AAA is not required to set privilege levels, but is required in order to create role-based views. What are two benefits of using a ZPF rather than a Classic Firewall? Explanation: While trying to hack a system, the most important thing is cracking the passwords. R1(config)# crypto isakmp key 5tayout! Administrators typically configure a set of defined rules that blocks or permits traffic onto the network. Forcepoint offers a suite of network security solutions that centralize and simplify what are often complex processes and ensure robust network security is in place across your enterprise. What type of policy defines the methods involved when a user sign in to the network? What is the best way to prevent a VLAN hopping attack? Cisco IOS ACLs utilize an implicit deny all and Cisco ASA ACLs end with an implicit permit all. Explanation: There are several benefits of a ZPF: It is not dependent on ACLs. The router security posture is to block unless explicitly allowed. Policies are easy to read and troubleshoot with C3PL. One policy affects any given traffic, instead of needing multiple ACLs and inspection actions. 153. It is commonly implemented over dialup and cable modem networks. It copies traffic that passes through a switch interface and sends the data directly to a syslog or SNMP server for analysis. R1(config)# crypto isakmp key cisco123 address 209.165.200.226, R1(config)# crypto isakmp key cisco123 hostname R1. 2) Which one of the following can be considered as the class of computer threats?

A honeypot is configured to entice attackers and allows administrators to get information about the attack techniques being used. 7. (Choose three.). The public zone would include the interfaces that connect to an external (outside the business) interface. So the correct option is A. You don't need to physically secure your servers as long as you use a good strong password for your accounts. 35) Which of the following principle of cyber security restricts how privileges are initiated whenever any object or subject is created? Both have a 30-day delayed access to updated signatures. The firewall will automatically allow HTTP, HTTPS, and FTP traffic from s0/0/0 to g0/0 and will track the connections. Explanation: Symmetric encryption algorithms use the same key (also called shared secret) to encrypt and decrypt the data. What is true about all security components and devices? Explanation: Deploy a Cisco SSL Appliance to decrypt SSL traffic and send it to intrusion prevention system (IPS) appliances to identify risks normally hidden by SSL. 139. According to the command output, which three statements are true about the DHCP options entered on the ASA? Explanation: Stateful firewalls cannot prevent application layer attacks because they do not examine the actual contents of the HTTP connection.

SuperScan is a Microsoft port scanning software that detects open TCP and UDP ports on systems. HMAC uses protocols such as SSL or TLS to provide session layer confidentiality. Traffic from the Internet and LAN can access the DMZ. To complete a partially typed command, ASA uses the Ctrl+Tab key combination whereas a router uses the Tab key. Place standard ACLs close to the source IP address of the traffic. 3. Ability to maneuver and succeed in larger, political environments. In short, we can also say that it is the first line of defense of the system to avoid several kinds of viruses. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network. The private or internal zone is commonly used for internal LANs. Virtual private networks (VPNs) create a connection to the network from another endpoint or site. Explanation: Secure segmentation is used when managing and organizing data in a data center. Which data loss mitigation technique could help with this situation? If the network traffic stream is encrypted, HIPS is unable to access unencrypted forms of the traffic. ii) Encoding is a reversible process, while encryption is not. In short, we can say that its primary work is to restrict or control the assignment of rights to the employees. B. client_hello Both keys are capable of the encryption process, but the complementary matched key is required for decryption. What network testing tool can be used to identify network layer protocols running on a host? Entering a second IP address/mask pair will replace the existing configuration. Which method is used to identify interesting traffic needed to create an IKE phase 1 tunnel? The ip verify source command is applied on untrusted interfaces. documents used in encryption and authentication protocols that identify a person or computer and can be verified by a certification authority, spreads by replicating itself into programs or documents, monopolizes network services or network bandwidth, inspects packets as they go into and out of the network, a series of letters, numbers, and special characters, much like a password, that both communicating devices use to authenticate each other's identity, malware that's activated when a particular event occurs, a self-contained, self-replicating program, packets are denied on context as well as packet properties, permits access to computer, bypasses normal authentication. Password Explanation: The advanced threat control and containment services of an ASA firewall are provided by integrating special hardware modules with the ASA architecture. The best software not only scans files upon entry to the network but continuously scans and tracks files.

The first 28 bits of a supplied IP address will be matched. (Choose two.). As a philosophy, it complements Which command raises the privilege level of the ping command to 7? Which of the following is not a feature of proxy server? Explanation: An application gateway firewall, also called a proxy firewall, filters information at Layers 3, 4, 5, and 7 of the OSI model. Network scanning is used to discover available resources on the network. 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. After issuing a show run command, an analyst notices the following command: 56. The "CHAP" is one of the many authentication schemes used by the Point To Point Protocol (PPP), which is a serial transmission protocol for wide networks Connections (WAN). Which two algorithms can be used to achieve this task? What tool should you use? It is a type of device that helps to ensure that communication between a This mode is referred to as a bump in the wire. NAT can be implemented between connected networks. List the four characteristics. RSA is an algorithm used for authentication. In which some top-level accessions were hidden in the big wooden horse-like structure and given to the enemy as a gift. If a public key encrypts the data, the matching private key decrypts the data. Explanation: Until the workstation is authenticated, 802.1X access control enables only Extensible Authentication Protocol over LAN (EAPOL), Cisco Discovery Protocol (CDP), and Spanning Tree Protocol (STP) traffic through the port to which the workstation is connected. The dhcpd auto-config outside command was issued to enable the DHCP server. ), Explanation: Digital signatures use a mathematical technique to provide three basic security services:Integrity; Authenticity; Nonrepudiation. 29. Network security combines multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls. Authorized users gain access to network resources, but malicious actors are blocked from carrying out exploits and threats. How do I benefit from network security? However, the CIA triad does not involve Authenticity. 54. Authentication, encryption, and passwords provide no protection from loss of information from port scanning. 82. A standalone system is vulnerable to the same risks as networked computers. (Choose three.). 84. The purpose of IKE Phase 2 is to negotiate a security association between two IKE peers. ), What are two differences between stateful and packet filtering firewalls? 53) In an any organization, company or firm the policies of information security come under__________. 47. Threat defense includes a firewall and intrusion prevention system (IPS). Explanation: Availability refers to the violation of principle, if the system is no more accessible. Devices within that network, such as terminal servers, have direct console access for management purposes. Which three statements are generally considered to be best practices in the placement of ACLs? The IPv6 access list LIMITED_ACCESS is applied on the S0/0/0 interface of R1 in the inbound direction. Match the security management function with the description. It can be possible that in some cases, hacking a computer or network can be legal. Security features that control that can access resources in the OS. HMAC can be used for ensuring origin authentication. Refer to the exhibit. Traffic originating from the inside network going to the DMZ network is not permitted. This is also known as codebreaking. Explanation: In general, Stalking refers to continuous surveillance on the target (or person) done by a group of people or by the individual person. Explanation: According to the show crypto map command output, all required SAs are in place, but no interface is currently using the crypto map. 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. Also, the dynamic keyword in the nat command indicates that it is a dynamic mapping. It is a kind of cyber attack in which one tries to make a machine (or targeted application, website etc.) Explanation: To protect against MAC and IP address spoofing, apply the IP Source Guard security feature, using the ip verify source command, on untrusted ports. (Choose two.). 22. Protection is twofold; it needs to protect data and systems from unauthorized personnel, and it also needs to protect against malicious activities from employees. Explanation: The RAT is an abbreviation of Remote Access Trojans or Remote Administration Tools, which gives the total control of a Device, which means it, can control anything or do anything in the target device remotely. It includes coverage of advance exploits by using the research work of the Cisco Talos security experts. It involves creating a secure infrastructure for devices, applications, users, and applications to work in a secure manner. What action will occur when PC1 is attached to switch S1 with the applied configuration? 39) The web application like banking websites should ask its users to log-in again after some specific period of time, let say 30 min. After authentication succeeds, normal traffic can pass through the port. 2. The main reason why the tails operating system is famous among the user is that it is almost untraceable, which keep your privacy secure. Now let's take a look at some of the different ways you can secure your network. 60) Name of the Hacker who breaks the SIPRNET system? Protecting vulnerabilities before they are compromised.
