This IDS defeating technique works by splitting a datagram (or packet) into multiple fragments and the IDS will not spot the true nature of the fully assembled datagram.

IP Routing or Packet Dropping

Anonymizer sites access the Internet on your behalf, protecting your personal information from disclosure. An anonymizer protects all of your computer's identifying information while it surfs for you, enabling you to remain at least one step removed from the sites you visit. You can visit Web sites without allowing anyone to gather information on sites visited by you. Services that provide anonymity disable pop-up windows and cookies, and conceal visitor's IP address. These services typically use a proxy server to process each HTTP request. When the user requests a Web page by clicking a hyperlink or typing a URL into their browser, the service retrieves and displays the information using its own server. The remote server (where the requested Web page resides) receives information on the anonymous Web surfing service in place of your information. In which situations would you want to use anonymizer? (Select 3 answers)
- A.
Increase your Web browsing bandwidth speed by using Anonymizer
- B.
To protect your privacy and Identity on the Internet

TCP SYN Flood attack uses the three-way handshake mechanism. 1. An attacker at system A sends a SYN packet to victim at system B. 2. System B sends a SYN/ACK packet to victim A. 3. As a normal three-way handshake mechanism system A should send an ACK packet to system B, however, system A does not send an ACK packet to system B. In this case client B is waiting for an ACK packet from client A. This status of client B is called _________________

You are the security administrator of Jaco Banking Systems located in Boston. You are setting up e-banking website (http://www.ejacobank.com) authentication system. Instead of issuing banking customer with a single password, you give them a printed list of 100 unique passwords. Each time the customer needs to log into the e-banking system website, the customer enters the next password on the list. If someone sees them type the password using shoulder surfing, MiTM or keyloggers, then no damage is done because the password will not be accepted a second time. Once the list of 100 passwords is almost finished, the system automatically sends out a new password list by encrypted e-mail to the ustomer. You are confident that this security implementation will protect the customer from password abuse. Two months later, a group of hackers called "HackJihad" found a way to access the one-time password list issued to customers of Jaco Banking Systems. The hackers set up a fake website (http://www.e-jacobank.com) and used phishing attacks to direct ignorant customers to it. The fake website asked users for their e-banking username and password, and the next unused entry from their one-time password sheet. The hackers collected 200 customer's username/passwords this way. They transferred money from the customer's bank account to various offshore accounts. Your decision of password policy implementation has cost the bank with USD 925,000 to hackers. You immediately shut down the e-banking website while figuring out the next best security solution. What effective security solution will you recommend in this case?
- A.
Implement Biometrics based passwordauthentication system. Record the customers face image to the authentication database
- B.
Configure your firewall to block logon attempts of more than three wrong tries
- C.
Enable a complex password policy of 20 characters and ask the user to change the password immediately after they logon and do not store password histories

The SYN flood attack sends TCP connections requests faster than a machine can process them. - Attacker creates a random source address for each packet - SYN flag set in each packet isa request to open a new connection to the server from the spoofed IP address - Victim responds to spoofed IP address, then waits for confirmation that never arrives (timeout wait is about 3 minutes) - Victim's connection table fills up waiting for replies andignores new connections - Legitimate users are ignored and will not be able to access the server How do you protect your network against SYN Flood attacks? (Choose all that apply)
- A.
SYN cookies. Instead of allocating a record, send a SYN-ACK with a carefully constructed sequencenumber generated as a hash of the clients IP address, port number, and other information. When the client responds with a normal ACK, that special sequence number will be included, which the server then verifies. Thus, the server first allocates memory onthe third packet of the handshake, not the first.
- B.
RST cookies - The server sends a wrong SYN/ACK back to the client. The client should then generate a RST packet telling the server that something is wrong. At this point, the server knows the client is valid and will now accept incoming connections from that client normally
- C.
Check the incoming packet's IP address with the SPAM database on the Internet and enable the filter using ACLs at the Firewall
- D.
Stack Tweaking. TCP stacks can be tweaked in orderto reduce the effect of SYN floods. Reduce the timeout before a stack frees up the memory allocated for a connection
- E.
Micro Blocks. Instead of allocating a complete connection, simply allocate a micro record of 16- bytes for the incoming SYN object
Correct Answer(s)
