Half-open TCP ports are also symptoms of a SYN flood or SYN-ACK attack SYN floods are classified as DoS attacks because their objective is to stop the server from responding to legitimate client requests During a SYN flood, the attacker attempts to send TCP connection request packets to a specific TCP port or ports faster than the target server can expire them A SYN flood consumes all of the server's available TCP connection resources so that it is unable to service new client requests One way to reduce the effects of such an attack is to reduce the time that a TCP port waits for an ACK response For more information on SYN attacks, review CERT Advisory CA-1996-21, "TCP SYN Flooding and IP Spoofing Attacks," available at http://wwwcertorg/advisories/CA-1996-21html FIN When a basic firewall or router blocks other TCP scans, the TCP FIN scan might succeed.

The FIN scan, like other TCP scans, is used to identify listening TCP ports based on a response, or lack of a response, to a finish (FIN) packet Attackers send the TCP FIN packet to the target host, even though they haven't previously made any connections to the target If the target responds with an RST packet, the TCP port solicited is closed If the target has an open TCP port, it discards the packet and doesn't respond No response is an indication of an open port (or at least a potentially open port), so an attacker can then follow up with other scans, connection attempts, or attempts to exploit services on the target system XMAS Another derivative TCP scan designed to bypass basic firewalls or routers with filtering capabilities is the XMAS scan (also called a Xmas tree scans).

When using Remote Desktop For Administration, you are creating a connection to a session running on the server. There are several potential causes of failed connections or problematic sessions:

This scan uses a series of varied TCP packets to identify listening TCP ports on target devices Some characteristics of XMAS scan packets include TCP sequence numbers of zero, and FIN, urgent (URG), or push (PSH) flags set Target devices send a TCP RST packet if their ports are closed Target devices discard XMAS packets and provide no.

1. You are creating an ASP.NET Web page that displays a list of customers gener ated by a database query. The user can filter the list so that only customers within a specific state are displayed. You want to maximize the performance of your Web application by using page output caching. You want to ensure users can filter by state, but you are not concerned about displaying updates to the list of customers because the customer list doesn t change very frequently. Which declarative @ OutputCache attribute should you configure A. VaryByParam B. VaryByHeader C. SqlDependency D. VaryByCustom 2. You need to programmatically configure page output caching. Which object would you use A. Request B. Response C. Application D. Server 3. You want to cache an object but have it automatically expire in 10 minutes. How can you do this (Choose all that apply.) A. Directly define the Cache item. B. Call Cache.Get. C. Call Cache.Insert. D. Call Cache.Add.
