“ ……. is an attack type for a rogue Wi-Fi access point that appears to be a legitimate one offered on the premises, but actually has been set up to eavesdrop on wireless communications. It is the wireless version of the phishing scam. An attacker fools wireless users into connecting a laptop or mobile phone to a tainted hot-spot by posing as a legitimate provider. This type of attack may be used to steal the passwords of unsuspecting users by either snooping the communication link or by phishing, which involves setting up a fraudulent web site and luring people there.”

What is one of the advantages of using both symmetric and asymmetric cryptography in SSL/TLS? Supporting both types of algorithms allows less-powerful devices such as mobile phones to use symmetric encryption instead. Symmetric algorithms such as AES provide a failsafe when asymmetric methods fail. Symmetric encryption allows the server to security transmit the session keys out-of-band. Asymmetric cryptography is computationally expensive in comparison. However, it is well-suited to securely negotiate keys for use with symmetric cryptography.

Supporting both types of algorithms allows less-powerful devices such as mobile phones to use symmetric encryption instead.

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? Bob can be right since DMZ does not make sense when combined with stateless firewalls Bob is partially right. He does not need to separate networks if he can create rules by destination IPs, one by one Bob is totally wrong. DMZ is always relevant when the company has internet servers and workstations Bob is partially right. DMZ does not make sense when a stateless firewall is available

Joseph was the Web site administrator for the Mason Insurance in New York, who's main Web site was located at www.masonins.com. Joseph uses his laptop computer regularly to administer the Web site. One night, Joseph received an urgent phone call from his friend, Smith. According to Smith, the main Mason Insurance web site had been vandalized! All of its normal content was removed and replaced with an attacker's message ''Hacker Message: You are dead! Freaks!” From his office, which was directly connected to Mason Insurance's internal network, Joseph surfed to the Web site using his laptop. In his browser, the Web site looked completely intact. No changes were apparent. Joseph called a friend of his at his home to help troubleshoot the problem. The Web site appeared defaced when his friend visited using his DSL connection. So, while Smith and his friend could see the defaced page, Joseph saw the intact Mason Insurance web site. To help make sense of this problem, Joseph decided to access the Web site using hisdial-up ISP. He disconnected his laptop from the corporate internal network and used his modem to dial up the same ISP used by Smith. After his modem connected, he quickly typed www.masonins.com in his browser to reveal the following web page: After seeing the defaced Web site, he disconnected his dial-up line, reconnected to the internal network, and used Secure Shell (SSH) to log in directly to the Web server. He ran Tripwire against the entire Web site, and determined that every system file and all the Web content on the server were intact. How did the attacker accomplish this hack?

A channel that transfers information within a computer system or network in a way that violates the security policy

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? Attacker generates TCP SYN packets with random destination addresses towards a victim host Attacker floods TCP SYN packets with random source addresses towards a victim host Attacker generates TCP ACK packets with random source addresses towards a victim host Attacker generates TCP RST packets with random source addresses towards a victim host

Attacker floods TCP SYN packets with random source addresses towards a victim host

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? Untrained staff or ignorant computer users who inadvertently become the weakest link in your security chain "Zero-day" exploits are the weakest link in the security chain since the IDS will not be able to detect these attacks "Polymorphic viruses" are the weakest link in the security chain since the Anti-Virus scanners will not be able to detect these attacks Continuous Spam e-mails cannot be blocked by your security system since spammers use different techniques to bypass the filters in your gateway

When configuring wireless on his home router, Javik disables SSID broadcast. He leaves authentication “open” but sets the SSID to a 32-character string of random letters and numbers. What is an accurate assessment of this scenario from a security perspective? Since the SSID is required in order to connect, the 32-character string is sufficient to prevent brute- force attacks. Disabling SSID broadcast prevents 802.11 beacons from being transmitted from the access point, resulting in a valid setup leveraging “security through obscurity”. It is still possible for a hacker to connect to the network after sniffing the SSID from a successful wireless association. Javik’s router is still vulnerable to wireless hacking attempts because the SSID broadcast setting can be enabled using a specially crafted packet sent to the hardware address of the access point.
