Step by step
Solved in 2 steps
- Which of the following statements about firewalls is true? A firewall with a packet filter may block harmful files. Firewalls with packet filters simply accept or reject data packets; they never provide feedback to the source. Each packet that travels through the firewall will be examined by the packet filter firewall. Firewalls using packet filters may examine the application layerLFirewalls: which is true? A packet filter firewall filters dangerous data. Packet filter firewalls just accept or deny packets without sending feedback to the sender. A packet filter firewall checks every network packet. Packet filtering firewalls check the application layer?
- Which of the following attacks leverage spoofed IP addresses? DNS cache poisoning attacks. RST reset attacks launched by a censor. DNS injection attacks launched by a censor. TCP session hijacking.Which of the following statements is NOT true? Question 46 options: IP Address Spoofing attacks can be prevented by using Stateful Firewalls Static Packet Filter Firewalls are Stateless (no session information recorded) Static Packet Filter Firewalls can deal with port-switching applications A Spoofed TCP SYN/ACK Segment can be dropped by a stateful inspection firewallWhat information is used by a typical packet-filtering firewall to filter traffic? (Select all that apply) a. Transport protocol header source port Ob. IP header source IP address O c. Application type Od. IP header destination IP address Oe. Transport protocol header destination port Of. Heuristic traffic signatures
- attack that exploits the TCP three-way handshake to consume resources on the targeted server and disable the server to respond to legitimate connection requests a. UPD Flood b. SYN SPOOFING c. ICMP Flood d. Ping to deathWhen it comes to firewalls, which of the following is TRUE? Using a packet filter firewall, harmful data may be filtered out. No feedback is ever sent to the sender when using a packet filter firewall; they just allow or disallow packets. Each data packet entering and leaving the network is inspected by a packet filter firewall. The application layer may be inspected by a packet filtering firewall.SNMP is a protocol used to manage network equipment and is supported by most network equipment manufacturers. Which of the following is not true about SNMP? Question 7 options: It allows administrators to remotely monitor, manage, and configure network devices. It can be used on networks of any size Security vulnerabilities were present in SMNP versions 3. SNMP allows exchanging management information between network devices.
- Hi Just need answer, no need explanation What kind of firewall only checks packet header information in individual packets to make decisions? Circuit-level gateway Application proxy Guard Screening router What kind of IDS builds a model of acceptable behavior so it can flag exceptions? Signature based Misuse based Host based Anomaly based What kind of firewall operates at OSI Layer 5 and can be used to implement a VPN? Circuit-level gateway Application proxy Guard Screening router What kind of firewall can correlate data across packets? Circuit-level gateway Application proxy Stateful inspection Screening router Software that aggregates security event data from multiple sources across a network is called a(n) ___________. IDS SIEM Honeypot IPSSelect the security policy that corresponds to the following set of filtering rules: Direction Source Destination IP IP Protocol Source port Destination port Syn Ack Type Code Action Out any any UDP Any 53 Deny Out Any any ICMP 8 0 Deny In Any any ICMP 8 0 Allow =================== Out any any ICMP 0 0 Allow O All internal hosts are allowed to communicate with the external UDP server (IP1). O All internal hosts are not allowed to access any internal UDP server (running on port 53) and to ping any external host, but external hosts are allowed to ping any internal host. O All internal hosts are not allowed to access any external UDP server (running on port 53) and to ping any external host, but external hosts are allowed to ping any internal host. O All interanl hosts are not allowed to send emails and to ping any internal host, but internal hosts are allowed to ping any internal host. All internal hosts are not allowed to receive emails, but are allowed to ping any external host.This Chain applies for all packets that are addressed to the firewall INPUT OUTPUT FORWARD This chain applies for all packets originating from firewall and going out of the server O INPUT ⒸOUTPUT FORWARD This chain applies for all packets passing through the firewall from other hosts on the network. The host with iptables is neither the source nor destination of the packet: mainly used to route packets through the machines on the network. INPUT OUTPUT Ⓒ FORWARD This jump target does not respond to a packet at all and does nothing with the packet. It an attack sends a packet. they would not get any response. ODROP ⒸREJECT This jump target responds with an ICMP Destination Unreachable back to the source. This indicates that a server exists, which is beneficial for troubleshooting and for attackers. DROP O REJECT
