The direction in which the traffic is examined (in or out) is also required. Which two types of attacks are examples of reconnaissance attacks? A packet filtering firewall will prevent spoofing by determining whether packets belong to an existing connection while a stateful firewall follows pre-configured rule sets. Which method is used to identify interesting traffic needed to create an IKE phase 1 tunnel? Administrators can configure Cisco IOS NetFlow on Cisco IOS routers and switches to aid in the identification of traffic flows that may be attempts to exploit these DNS implementation flaws. UDP Flood Attacks. Traffic originating from the inside network going to the DMZ network is selectively permitted. Privilege levels cannot specify access control to interfaces, ports, or slots. ! (Choose two. Which network monitoring technology uses VLANs to monitor traffic on remote switches? The Domain Name Service (DNS) protocol defines an automated service that matches resource names, such as www.cisco.com, with the required numeric network address, such as the IPv4 or IPv6 address. Both are fully supported by Cisco and include Cisco customer support. The firewall will automatically drop all HTTP, HTTPS, and FTP traffic. Also, an IDS often requires assistance from other networking devices, such as routers and firewalls, to respond to an attack. Explanation: A site-to-site VPN is created between the network devices of two separate networks. Cisco Secure Firewall ASA Series Syslog Messages . 140. An IDS can negatively impact the packet flow, whereas an IPS can not. When the Cisco NAC appliance evaluates an incoming connection from a remote device against the defined network policies, what feature is being used? The idea is that passwords will have been changed before an attacker exhausts the keyspace. verified attack traffic is generating an alarmTrue positive, normal user traffic is not generating an alarmTrue negative, attack traffic is not generating an alarmFalse negative, normal user traffic is generating an alarmFalse positive. 102.

Several configuration examples are available in the Prevent DNS Open Resolver Configurations above to prevent or restrict your server from responding to recursive DNS queries. Overview What is DNS? Multiple vendors have products that implement the DNS protocol and that can be configured as a DNS open resolver intentionally or unintentionally. 26. 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. (Choose two.). MIB files repository. Which type of firewall is the most common and allows or blocks traffic based on Layer 3, Layer 4, and Layer 5 information? 115. Tracking the connection allows only return traffic to be permitted through the firewall in the opposite direction. Fix the ACE statements so that it works as desired inbound on the interface. Password requirements: 6 to 30 characters long; ASCII characters only (characters found on a standard US keyboard); must contain at least 4 different symbols; Enable DHCP snooping on VLAN 100 It mitigates MAC address overflow attacks. ICMP 109260 0.0 3 125 0.0 23.7 52.5 In general, the following traffic profiles will be associated with these types of attacks; however it is important to note, that depending on NetFlow monitoring location, Network or Port address translation (NAT or PAT) and other variables that these are not absolutes. Both keys are capable of the encryption process, but the complementary matched key is required for decryption. HIPS installations are vulnerable to fragmentation attacks or variable TTL attacks. To defend against the brute-force attacks, modern cryptographers have as an objective to have a keyspace (a set of all possible keys) large enough so that it takes too much money and too much time to accomplish a brute-force attack. Devices within that network, such as terminal servers, have direct console access for management purposes. Authorization is concerned with allowing and disallowing authenticated users access to certain areas and programs on the network. What would be the primary reason an attacker would launch a MAC address overflow attack? 16. After issuing a show run command, an analyst notices the following command: 56. These example configurations show how to prevent a DNS server from acting as an open resolver. Another potentially malicious use of a short TTL is using a value of 0.

Although it can easily be used in business environments (hospitality, office, education, retail shops etc), because of its low price, compact design and 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. Inactive flows timeout in 60 seconds This message resulted from an unusual error requiring reconfiguration of the interface. They provide confidentiality, integrity, and availability. (Choose two.). This code is changed every day. Firewall syslog message106007will be generated when the firewall detects that a DNS response message has already been received for a DNS query message and the connection entry has been torn down by the DNS guard function. represents the root zone. ), In an attempt to prevent network attacks, cyber analysts share unique identifiable attributes of known attacks with colleagues. This document is part of the Cisco Security portal. These controls are described in the following sections. 110. Verify Snort IPS. ), Match each SNMP operation to the corresponding description. This is also known as codebreaking. Refer to the exhibit. What will be the result of failed login attempts if the following command is entered into a router? Secure Copy Protocol (SCP) conducts the authentication and file transfer under SSH, thus the communication is encrypted. This tool can also be used for stateful benchmark and stress testing load balancers, ISPs, DPI, NAT, and firewall protection as well as stateless traffic stream generation. There can only be one statement in the network object. A corresponding policy must be applied to allow return traffic to be permitted through the firewall in the opposite direction. Match the IPS alarm type to the description. BIND also allows operators to define views that can use the following configuration methods for disabling recursion. If a private key is used to encrypt the data, a private key must be used to decrypt the data. The standard defines the format of a digital certificate. However, because it requires DHCP to remain manageable, it is not possible to deploy IP source guard on internal-to-external network boundaries. Frames from PC1 will be forwarded to its destination, but a log entry will not be created. installing the maximum amount of memory possible. 54. OSPF authentication does not provide faster network convergence, more efficient routing, or encryption of data traffic. 90. 85. (Choose three.). Explanation: To deploy Snort IPS on supported devices, perform the following steps: Step 1. A company has a file server that shares a folder named Public. ACLs provide network traffic filtering but not encryption. ), Explanation: Digital signatures use a mathematical technique to provide three basic security services:Integrity; Authenticity; Nonrepudiation. An example is a 'DNS Referral Response Message', in which the Answer section is empty, but the Authority and Additional sections are present and contain RR information. Authoritative and recursive resolvers have different primary functions. (Choose two.). 63. Place extended ACLs close to the destination IP address of the traffic.

What statement describes the risk of access to cloud storage devices? If the resolver is a recursive or open resolver, then it can distribute the RRs for the malicious host to many resolver clients, thus allowing use for malicious activities. The IOS do command is not required or recognized. Explanation: Manual configuration of the single allowed MAC address has been entered for port fa0/12. A network administrator configures AAA authentication on R1. Operators can use the 'allow-recursion-on' configuration option to select which addresses on the DNS server will accept recursive DNS queries. (Not all options are used.). Explanation: The message is a level 5 notification message as shown in the %LINEPROTO-5 section of the output. deny ip 10.0.0.0 0.255.255.255 any Place extended ACLs close to the source IP address of the traffic. If the next UDP source port value used in the DNS query along with the transaction ID can be predicted, an attacker can construct and send spoofed DNS messages with the correct UDP source port. All other traffic is allowed. IP Flow Switching Cache, 4456704 bytes All devices must be insured against liability if used to compromise the corporate network. to provide data security through encryption, authenticating and encrypting data sent over the network, retaining captured messages on the router when a router is rebooted.

The date and time displayed at the beginning of the message indicates that service timestamps have been configured on the router. What are two security measures used to protect endpoints in the borderless network? Refer to the exhibit. The following example provides information on how to disable recursion for the DNS Server service using the Windows Command-Line) CLI. The configuration of this feature, when configurable, will be detailed later in the feature configuration section. 46. Which parameter can be used in extended ACLs to meet this requirement? This informs the DNS resolver where to send queries in order to obtain authoritative information for the question in the DNS query. Loose mode Unicast RPF can be enabled on Cisco IOS devices using theip verify source reachable-via anyinterface configuration command; loose mode Unicast RPF is not available on Cisco PIX, ASA or FWSM firewalls. Which security measure is best used to limit the success of a reconnaissance attack from within a campus area network? Our global writing staff includes experienced ENL & ESL academic writers in a variety of disciplines. Theshow asp drop framecommand can identify the number of DNS packets that the DNS guard function (with the counter nameinspect-dns-id-not-matched) has dropped because the transaction ID in the DNS response message does not match any transaction IDs for DNS queries that have passed across the firewall earlier on the same connection. The examples that follow are configurations for some vendor products that are broadly deployed throughout the Internet. 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. 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? PKI certificates are public information and are used to provide authenticity, confidentiality, integrity, and nonrepudiation services that can scale to large requirements. The implementation of a firewall on the network edge may prevent reconnaissance attacks from the Internet, but attacks within the local network are not prevented. (Choose two.). These RFCs were made obsolete byRFC 1034andRFC 1035and have been updated by multiple RFCs over the years. 123. Explanation: According to the show crypto map command output, all required SAs are in place, but no interface is currently using the crypto map. The DHS Acronyms, Abbreviations, and Terms (DAAT) list contains homeland security related acronyms, abbreviations, and terms. DNS amplification and reflection attacks use DNS open resolvers to increase the volume of attacks and to hide the true source of an attack, actions that typically result in a DoS or DDoS attack.

A researcher is comparing the differences between a stateless firewall and a proxy firewall. IPINIP 12 0.0 2 20 0.0 1.1 60.8 The code has not been modified since it left the software publisher. All devices must have open authentication with the corporate network. To use these configurations, apply them to the options section in the 'named.conf' configuration file. A security service company is conducting an audit in several risk areas within a major corporation. In addition to these application specific signatures, anomaly-based signatures can provide coverage for vulnerabilities such as amplification attacks or cache poisoning, where the rate of DNS transactions are likely to vary significantly. 53 What is the next step in the establishment of an IPsec VPN after IKE Phase 1 is complete? What ports can receive forwarded traffic from an isolated port that is part of a PVLAN? parameters Hence you can not start it again. OOB management requires the creation of VPNs. These messages provide additional information about denied packets. Explanation: The IPsec framework consists of five building blocks. You must sign in or sign up to start the quiz. Andr LAGUERRE. A single superview can be shared among multiple CLI views. DNS application inspection utilizes the Modular Policy Framework (MPF) for configuration. 73. The Subscriber Rule Set also provides the fastest access to updated signatures in response to a security incident or the proactive discovery of a new threat. Like FTP, TFTP transfers files unencrypted. The tunnel configuration was established and can be tested with extended pings. 65. A technician is to document the current configurations of all network devices in a college, including those in off-site buildings. This message indicates that the interface should be replaced. /dev/randomis recommended because it creates an entropy pool (a group of random bits stored in one place) for generating unpredictable random numbers. Thanks so much, how many question in this exam? Caution:Application layer protocol inspection will decrease firewall performance. 39. The username and password would be easily captured if the data transmission is intercepted. Additional information about this syslog message is available inCisco Security Appliance System Log Message - 106007. Which protocol would be best to use to securely access the network devices? (Choose two.). What service provides this type of guarantee? A tool that will monitor and display DNS messages seen on the network. and have been updated by multiple RFCs over the years. DNSSEC adds data origin authentication and data integrity to the DNS protocol. Explanation: Digitally signing code provides several assurances about the code:The code is authentic and is actually sourced by the publisher.The code has not been modified since it left the software publisher.The publisher undeniably published the code. The IPv6 access list LIMITED_ACCESS is applied on the S0/0/0 interface of R1 in the inbound direction. 77. For every inbound ACL placed on an interface, there should be a matching outbound ACL. 79.

DNS Application Inspection Application layer protocol inspection is available beginning in software release 7.0 for the Cisco ASA 5500 and Cisco PIX 500 Series Firewalls and in software release 3.1 for the FWSM Firewall. Which command is used to activate an IPv6 ACL named ENG_ACL on an interface so that the router filters traffic prior to accessing the routing table? If the network traffic stream is encrypted, HIPS is unable to access unencrypted forms of the traffic. Flaws in the implementation of the DNS protocol allow it to be exploited and used for malicious activities. Each attack has unique identifiable attributes. Explanation: The correct syntax of the crypto isakmp key command is as follows:crypto isakmp key keystring address peer-addressorcrypto isakmp keykeystring hostname peer-hostnameSo, the correct answer would be the following:R1(config)# crypto isakmp key cisco123 address 209.165.200.227R2(config)# crypto isakmp key cisco123 address 209.165.200.226, 143. To exploit this flaw in the DNS resolver implementation so it will store the falsified information, an attacker must be able to correctly predict the DNS transaction identifier (TXID) and the UDP source port for the DNS query (request) message. Explanation: Confidentiality ensures that data is accessed only by authorized individuals. A web server administrator is configuring access settings to require users to authenticate first before accessing certain web pages. 124. 27. RADIUS provides encryption of the complete packet during transfer. This method differs from the Fast-Flux technique that uses a short TTL value and operators are able to use traceback techniques to more easily identify malicious hosts distributing this information. HMAC can be used for ensuring origin authentication. 6. Deleting a superview does not delete the associated CLI views. Which three statements are generally considered to be best practices in the placement of ACLs? Data center visibility is designed to simplify operations and compliance reporting by providing consistent security policy enforcement. Note:The source addresses of the DNS servers used in this attack scenario are typically DNS open resolvers. The public zone would include the interfaces that connect to an external (outside the business) interface. If a CSRF attack is detected, a user is notified by warning messages. Which three types of traffic are allowed when the authentication port-control auto command has been issued and the client has not yet been authenticated? Information about configuring syslog on the FWSM for Cisco Catalyst 6500 Series switches and Cisco 7600 Series routers is available inConfiguring Monitoring and Logging on the Cisco FWSM. Require remote access connections through IPsec VPN. Decisions on placing ACLs inbound or outbound are dependent on the requirements to be met. Explanation: Symmetric encryption algorithms use the same key (also called shared secret) to encrypt and decrypt the data. NOTE: If you have the new question on this test, please comment Question and Multiple-Choice list in form below this article. Table 2. What two assurances does digital signing provide about code that is downloaded from the Internet? This makes these implementations prone to cache poisoning and spoofing attacks. Which three statements are generally considered to be best practices in the placement of ACLs? DNS uses both the source port value and transaction ID for tracking queries and the responses to queries. Multiple inspection actions are used with ZPF. Match each SNMP operation to the corresponding description. Explanation: VLAN hopping attacks rely on the attacker being able to create a trunk link with a switch. What is the purpose of mobile device management (MDM) software? The VPN is static and stays established. If a private key is used to encrypt the data, a public key must be used to decrypt the data. Which command raises the privilege level of the ping command to 7? Buy an IPS. Queries from known sources (clients inside your administrative domain) may be allowed for information we do not know (for example, for domain name space outside our administrative domain). Chapter Title. ASA uses the ? Indicators of compromise are the evidence that an attack has occurred. This technique can be used for storing malicious RR information in the cache of a resolver for an extended period of time. Third, create the user IDs and passwords of the users who will be connecting. By default, they allow traffic from more secure interfaces (higher security level) to access less secure interfaces (lower security level). so that the switch stops forwarding traffic, so that legitimate hosts cannot obtain a MAC address, so that the attacker can execute arbitrary code on the switch. The logging service stores messages in a logging buffer that is time-limited, and cannot retain the information when a router is rebooted. What action should the administrator take first in terms of the security policy? 17. This white paper provides information on general best practices, network protections, and attack identification techniques that operators and administrators can use for implementations of the Domain Name System (DNS) protocol. Explanation: Snort IPS mode can perform all the IDS actions plus the following: Drop Block and log the packet. Reject Block the packet, log it, and then send a TCP reset if the protocol is TCP or an ICMP port unreachable message if the protocol is UDP. Sdrop Block the packet but do not log it. Explanation: Asymmetric algorithms use two keys: a public key and a private key. Nmap and Zenmap are low-level network scanners available to the public. Cisco IOS ACLs are processed sequentially from the top down and Cisco ASA ACLs are not processed sequentially. What are two security features that are commonly found in such a network configuration? SrcIf SrcIPaddress DstIf DstIPaddress Pr SrcP DstP Pkts 70. To understand DNS and the DNS-specific recommendations in this document, it is important that operators and administrators are familiar with the following terms: DNS primarily translates hostnames to IP addresses or IP addresses to hostnames. Which type of firewall is supported by most routers and is the easiest to implement? Traffic from the Internet and LAN can access the DMZ. The code is authentic and is actually sourced by the publisher. Once this information has been gathered and stored in the DHCP snooping bindings table, IP source guard is able to leverage it to filter IP packets received by a network device. The analyst has just downloaded and installed the Snort OVA file. Cisco Secure network security products include firewalls, intrusion prevention systems, secure access systems, security analytics, and malware defense. Disabling the Spanning Tree Protocol (STP) will not eliminate VLAN hopping attacks. The impact of these attacks may require the device to be rebooted or a service to be stopped and restarted. Explanation: The IPsec framework uses various protocols and algorithms to provide data confidentiality, data integrity, authentication, and secure key exchange. ! This syslog message indicates that the DNS response message received has been denied. Match each IPS signature trigger category with the description.Other case: 38. The function of providing confidentiality is provided by protocols such as DES, 3DES, and AES. The Cisco IPS provides several signatures to detect application specific vulnerabilities such as buffer overflow vulnerabilities as well as informational DNS signatures that may be indicative of reconnaissance or probing. This lets us find the most appropriate writer for any type of assignment. 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. Enable IPS globally or on desired interfaces. The last four bits of a supplied IP address will be matched.

Only a root view user can configure a new view and add or remove commands from the existing views.. Safeguards must be put in place for any personal device being compromised. Which threat protection capability is provided by Cisco ESA? Note:The example configurations for BIND will use version 9.5. MD5 and SHA-1 can be used to ensure data integrity. Traffic that is originating from the public network is usually permitted with little or no restriction when traveling to the DMZ network. IKE Phase 1 can be implemented in three different modes: main, aggressive, or quick. Example output for show service-policy inspect dns follows. Refer to the exhibit. With ZPF, the router will allow packets unless they are explicitly blocked. Those who have a checking or savings account, but also use financial alternatives like check cashing services are considered underbanked. *0035 interface Ethernet 0/0 Microsoft Windows also provides a feature calledDNS Server Secure Cache Against Pollutionthat ignores the RRs in DNS response messages received from a non-authoritative server. What function is performed by the class maps configuration object in the Cisco modular policy framework? Use ISL encapsulation on all trunk links. !

Which pair of crypto isakmp key commands would correctly configure PSK on the two routers? A tool that collections all available information for a sub-domain. Upon completion of a network security course, a student decides to pursue a career in cryptanalysis. Operators may also configure BIND to only listen on specific interfaces using the 'listen-on' or 'listen-on-v6' options configuration. One approach for controlling what DNS queries are permitted to exit the network under an operators control is to only allow DNS queries sourced from the internal recursive DNS resolvers. (Choose two.). An IDS needs to be deployed together with a firewall device, whereas an IPS can replace a firewall. router#show ip cache flow What algorithm will be used for providing confidentiality? The following guidelines assume no Port Address Translation (PAT). Cisco Secure network security products include firewalls, intrusion prevention systems, secure access systems, security analytics, and malware defense. Activate the virtual services. Step 5. Recent Comments. 118. Placing a standard ACL close to the source may have the effect of filtering all traffic, and limiting services to other hosts. Buy an ASA. Cisco ESA includes many threat protection capabilities for email such as spam protection, forged email detection, and Cisco advanced phishing protection. The underbanked represented 14% of U.S. households, or 18. 82. A tool that attempts to collect all possible information available for a domain. Which Cisco solution helps prevent ARP spoofing and ARP poisoning attacks? The ACEs that make up this ACL are not comprehensive. What are two security features commonly found in a WAN design? If a private key encrypts the data, the corresponding public key decrypts the data. PolicyDefines business intent including creation of virtual DNS cache poisoning occurs when an attacker sends falsified and usually spoofed RR information to a DNS resolver. 97. After authentication succeeds, normal traffic can pass through the port. The firewall also monitors the message exchange to ensure that the transaction ID of the DNS reply matches the transaction ID of the initial DNS query. Explanation: Packet Filtering (Stateless) Firewall uses a simple policy table look-up that filters traffic based on specific criteria and is considered the easiest firewall to implement. Messages reporting the link status are common and do not require replacing the interface or reconfiguring the interface. Views are not discussed in this document.
