Antivirus, anti-spyware, and firewall software can very easily detect these type of attacks

When a normal TCP connection starts, a destination host receives a SYN (synchronize/start) packet from a source host and sends back a SYN/ACK (synchronize acknowledge). The destination host must then hear an ACK (acknowledge) of the SYN/ACK before the connection is established. This is referred to as the "TCP three-way handshake." While waiting for the ACK to the SYN ACK, a connection queue of finite size on the destination host keeps track of connections waiting to be completed. This queue typically empties quickly since the ACK is expected to arrive a few milliseconds after the SYN ACK. How would an attacker exploit this design by launching TCP SYN attack? A. Attacker generates TCP SYN packets with random destination addresses towards a victim host B. Attacker floods TCP SYN packets with random source addresses towards a victim host C. Attacker generates TCP ACK packets with random source addresses towards a victim host D. Attacker generates TCP RST packets with random source addresses towards a victim host

Bob, a system administrator at TPNQM SA, concluded one day that a DMZ is not needed if he properly configures the firewall to allow access just to servers/ports, which can have direct internet access, and block the access to workstations. Bob also concluded that DMZ makes sense just when a stateful firewall is available, which is not the case of TPNQM SA. In this context, what can you say? A. Bob can be right since DMZ does not make sense when combined with stateless firewalls B. Bob is partially righ C. He does not need to separate networks if he can create rules by destination IPs, one by one D. Bob is totally wron E. DMZ is always relevant when the company has internet servers and workstations F. Bob is partially righ G. DMZ does not make sense when a stateless firewall is available

He does not need to separate networks if he can create rules by destination IPs, one by one

An attacker with access to the inside network of a small company launches a successful STP manipulation attack. What will he do next? A. He will create a SPAN entry on the spoofed root bridge and redirect traffic to his computer. B. He will activate OSPF on the spoofed root bridge. C. He will repeat this action so that it escalates to a DoS attack. D. He will repeat the same attack against all L2 switches of the network.

He will create a SPAN entry on the spoofed root bridge and redirect traffic to his computer.

To reach a bank web site, the traffic from workstations must pass through a firewall. You have been asked to review the firewall configuration to ensure that workstations in network 10.10.10.0/24 can only reach the bank web site 10.20.20.1 using https. Which of the following firewall rules meets this requirement? A. If (source matches 10.10.10.0/24 and destination matches 10.20.20.1 and port matches 443) then permit B. If (source matches 10.10.10.0/24 and destination matches 10.20.20.1 and port matches 80 or 443) then permit C. If (source matches 10.20.20.1 and destination matches 10.10.10.0/24 and port matches 443) then permit D. If (source matches 10.10.10.0 and destination matches 10.20.20.1 and port matches 443) then permit

If (source matches 10.10.10.0/24 and destination matches 10.20.20.1 and port matches 443) then permit

What does the -oX flag do in an Nmap scan? A. Perform an eXpress scan B. Output the results in truncated format to the screen C. Output the results in XML format to a file D. Perform an Xmas scan

Output the results in XML format to a file

Which of the following is the structure designed to verify and authenticate the identity of individuals within the enterprise taking part in a data exchange? A. SOA B. biometrics C. single sign on D. PKI

PKI

What is not a PCI compliance recommendation? A. Use a firewall between the public network and the payment card data. B. Use encryption to protect all transmission of card holder data over any public network. C. Rotate employees handling credit card transactions on a yearly basis to different departments. D. Limit access to card holder data to as few individuals as possible.

Rotate employees handling credit card transactions on a yearly basis to different departments.

You are trying to break into a highly classified top-secret mainframe computer with highest security system in place at Merclyn Barley Bank located in Los Angeles. You know that conventional hacking doesn't work in this case, because organizations such as banks are generally tight and secure when it comes to protecting their systems. In other words, you are trying to penetrate an otherwise impenetrable system. How would you proceed? A. Look for "zero-day" exploits at various underground hacker websites in Russia and China and buy the necessary exploits from these hackers and target the bank's network B. Try to hang around the local pubs or restaurants near the bank, get talking to a poorly-paid or disgruntled employee, and offer them money if they'll abuse their access privileges by providing you with sensitive information C. Launch DDOS attacks against Merclyn Barley Bank's routers and firewall systems using 100, 000 or more "zombies" and "bots" D. Try to conduct Man-in-the-Middle (MiTM) attack and divert the network traffic going to the Merclyn Barley Bank's Webserver to that of your machine using DNS Cache Poisoning techniques

You went to great lengths to install all the necessary technologies to prevent hacking attacks, such as expensive firewalls, antivirus software, anti-spam systems and intrusion detection/prevention tools in your company's network. You have configured the most secure policies and tightened every device on your network. You are confident that hackers will never be able to gain access to your network with complex security system in place. Your peer, Peter Smith who works at the same department disagrees with you. He says even the best network security technologies cannot prevent hackers gaining access to the network because of presence of "weakest link" in the security chain. What is Peter Smith talking about? A. Untrained staff or ignorant computer users who inadvertently become the weakest link in your securitychain B. "zero-day" exploits are the weakest link in the security chain since the IDS will not be able to detect these attacks C. "Polymorphic viruses" are the weakest link in the security chain since the Anti-Virus scanners will not be able to detect these attacks D. Continuous Spam e-mails cannot be blocked by your security system since spammers use different techniques to bypass
