태터캠프(TatterCamp)에 여러분을 초대합니다~
무더위가 찾아오는 7월, 네번째 태터캠프가 열립니다.
프로젝트 태터툴즈나 텍스트큐브에 대해 함께 이야기를 나누고 싶으신 분들, 프로젝트 태터툴즈와 텍스트큐브에 대해서 궁금했던 점들과 바라는 생각들을 한자리에서 같이 펼쳐놓는 자리를 만들고자 합니다. 누구라도 상관없습니다. 태터툴즈/텍스트큐브를 사랑하는 당신이 바로 이 자리의 주인공이니까요~ ^^

태터캠프(TatterCamp)란 어떤건가요?
태터캠프가 어떤건지 궁금하시죠? 캠프라고 하니 뭔가 모닥불이 연상되면서 밤을 새워야 할 것 같은 느낌이 들지도 모르겠네요. :) 태터캠프라는 이름이 왠지 익숙한 분들은 아마도 바캠프(http://barcamp.org/)를 아시는 분들이 아닐까 합니다.

맞습니다. 태터캠프는 프로젝트 태터툴즈와 텍스트큐브에 관해서 자유롭게 이야기를 나눌 수 있는 자리로 마련이 되었고 형식은 바캠프와 비슷합니다. 다만 바캠프가 발표하는 분들을 위주로 프로그램이 짜여졌다면 태터캠프는 발표자만이 아닌 프로젝트 태터툴즈와 텍스트큐브를 아끼는 모든 분들에게 문을 열어놨다는 점이 다르겠죠? 태터캠프는 그 자리에 참여하는 모든 분들이 함께 행사를 만들어가는 재미있는 모임이 될 것입니다.

태터캠프(TatterCamp)는 이렇게 열립니다
태터캠프는 발표자 한사람의 이야기를 들으러 오는 자리가 아닙니다. 태터캠프에 참석하는 여러분들이 그 자리에서 여러분의 이야기를 꺼내놓고 그 주제에 대해 함께 토론하고 공감하는 자리입니다. 이제 함께 그 고민과 생각들을 나눠보세요! 프로젝트 태터툴즈와 텍스트큐브에 대한 이야기라면 무엇이든 상관없습니다. :)

   6. 그럼 발표를 안하시는 분들은 참석못하나요? - 전혀 그런 염려는 없으셔도 되고요~ 발표에 대한 부담감을 전혀 가지지 않고 편하게 오셔서 이야기에 참여하시면 됩니다. 이야기를 듣는 것을 좋아하시는 분들은 그냥 태터캠프에서 재미있게 이야기를 들으시면 됩니다. ^^ 함께 이야기에 참여하면서 다른 분들의 생각도 접해보고 본인이 갖고 있는 생각도 같이 전해보세요.

태터캠프 발표 구성

   1. 세션은 총 3개의 세션으로 나뉩니다. 각 세션마다 두개의 트랙이 있고요 각 트랙마다 두명씩 발표를 하시게 됩니다.
   2. 태터캠프에 발표자로 참석하시는 분들이 당일 포스트잇에 발표할 주제를 적고 스케줄표에 붙입니다. 이 때 발표순서는 발표자들끼리 편하게 정하시면 됩니다. 발표하시는 분들은 태터캠프 행사가 시작되기 전에 조금씩만 일찍 와주시면 좋겠구요. 만약 늦게 도착하시면 TNF에서 뒷시간대에서 임의의 시간대로 배정하게 됩니다. 만약 피치못할 사정으로 인해 참석을 못하시게 되면 행사전에 꼭 연락주세요.
   3. 발표 스케줄이 정해지면 각 세션의 발표자들이 협의하여 세션의 전체 프로그램을 진행할 매니저를 선정합니다. 선정된 매니저는 각 세션의 진행을 이끄는 일을 하게 됩니다.(어려운게 아니고요 "다음 발표는 누구입니다~" 이거 말하는 사람 뽑는겁니다~)
   4. 참석한 모든 분들이 자신이 관심있는 주제를 찾아 작은 규모로 그룹을 만들고 자리를 조정합니다.
   5. 관심있는 주제에 따라 그룹이 만들어지면 발표자가 주도하여 해당 주제에 대한 이야기를 함께 나눕니다. 진행에 대해서는 발표자에게 모든 권한을 드릴거구요. 발표자는 어떤 형식으로 발표하셔도 상관없습니다.발표를 하시면서 그룹의 구성원들과 자유롭게 이야기를 나누시면 됩니다.

FAQ

Q1: 꼭 발표를 해야하나요?
A1: 아닙니다. 하지만, 발표를 하면서 캠프에 참여하는 것이 그냥 듣기만 하는 것 보다 훨씬 재미있으며, 이번 행사가 일종의 실험이기에 자기가 나누고 싶던 주제에 대해서 이렇게 편하게 발표할 기회가 다시는 오지 않을수 있다는 점을 고려한다면 발표하는 것을 강력히 추천드립니다.

Q2: 발표를 하고는 싶지만 어떠한 주제를 어떻게 발표해야 할지 감이 잡히지 않습니다.
A2: 프로젝트 태터툴즈나 텍스트큐브와 관련되어 있다면, 어떠한 주제라도 상관 없습니다. 중요한 것은 주제보다 주제를 통해 나누는 것이죠. 이번 태터캠프의 기본 발표시간은 30분이며, 20분 발표 10분 토론/질의응답의 구조를 기초로 합니다. 하지만 주어진 시간의 사용은 발표자의 자유입니다. 울렁증이 심해서 5분이상 발표는 힘들지만(^^;), 꼭 나눠보고 싶은 주제가 있으신 분은 주제에 대해서 5분 정도의 짧은 설명과 나머지 시간을 다양한 이야기를 듣는데 사용하시면 됩니다.

Q3: 일정이 너무 빠듯한 것 같습니다.
A3: 그게 6월로 의논되었다가 다들 바빠져서... 8월에는 다들 휴가가야 한다고 해서 일정이 7월로 잡혔는데, 대학생들 계절학기 중간고사 피하고 그러다 보니...

Q4: 뒷풀이는 있나요?
A4: 공식적으로 준비된 뒷풀이는 없습니다. 비공식적인 뒷풀이 조직은 얼마든지 환영합니다.

ECO-350
1.Samuel is the network administrator of DataX Communications, Inc. He is trying to configure his firewall to block password brute force attempts on his network. He enables blocking the intruder's IP address for a period of 24 hours time after more than three unsuccessful attempts. He is confident that this rule will secure his network from hackers on the Internet. But he still receives hundreds of thousands brute-force attempts generated from various IP addresses around the world. After some investigation he realizes that the intruders are using a proxy somewhere else on the Internet which has been scripted to enable the random usage of various proxies on each request so as not to get caught by the firewall rule. Later he adds another rule to his firewall and enables small sleep on the password attempt so that if the password is incorrect, it would take 45 seconds to return to the user to begin another attempt. Since an intruder may use multiple machines to brute force the password, he also throttles the number of connections that will be prepared to accept from a particular IP address. This action will slow the intruder's attempts. Samuel wants to completely block hackers brute force attempts on his network. What are the alternatives to defending against possible brute-force password attacks on his site?
A.Enforce a password policy and use account lockouts after three wrong logon attempts even though this might lock out legit users
B.Enable the IDS to monitor the intrusion attempts and alert you by e-mail about the IP address of the intruder so that you can block them at the Firewall manually
C.Enforce complex password policy on your network so that passwords are more difficult to brute force
D.You cannot completely block the intruders attempt if they constantly switch proxies
Correct:D
2.Which programming language is NOT vulnerable to buffer overflow attacks?
A.Java
B.ActiveX
C.C++
D.Assembly Language
Correct:A
3.A client has approached you with a penetration test requirement. They are concerned with the possibility of external threat, and have invested considerable resources in protecting their Internet exposure. However, their main concern is the possibility of an employee elevating his/her privileges and gaining access to information outside of their department. What kind of penetration test would you recommend that would best address the client's concern?
A.A Grey Hat test
B.A Grey Box test
C.A Black Hat test
D.A White Hat test
E.A Black Box test
F.A White Box test
Correct:B
4.What type of port scan is shown below? Scan directed at open port: ClientServer 192.5.2.92:4079 ---------FIN--------->192.5.2.110:23 192.5.2.92:4079 <----NO RESPONSE------192.5.2.110:23 Scan directed at closed port: ClientServer 192.5.2.92:4079 ---------FIN--------->192.5.2.110:23 192.5.2.92:4079<-----RST/ACK----------192.5.2.110:23

D.strsock()
Correct:A B C
6.Bob is acknowledged as a hacker of repute and is popular among visitors of 'underground' sites. Bob is willing to share his knowledge to those who are willing to learn, and many have expressed their interest in learning from him. However, this knowledge has risks associated with it, as the same knowledge can be used for malevolent attacks as well. In this context, what would be the most effective method to bridge the knowledge gap between the "black" hats or crackers and the "white" hats or computer security professionals?
A.Hire more computer security monitoring personnel to monitor computer systems and networks
B.Educate everyone with books, articles and training on risk analysis, vulnerabilities and safeguards
C.Train more national guard and reservist in the art of computer security to help out in times of emergency or crises
D.Make obtaining either a computer security certification or accreditation easier to achieve so more individuals feel that they are a part of something larger than life
Correct:B
7.After a client sends a connection request (SYN) packet to the server, the server will respond (SYN-ACK) with a sequence number of its choosing, which then must be acknowledged (ACK) by the client. This sequence number is predictable; the attack connects to a service first with its own IP address, records the sequence number chosen, and then opens a second connection from a forged IP address. The attack doesn't see the SYN-ACK (or any other packet) from the server, but can guess the correct responses. If the source IP address is used for authentication, then the attacker can use the one-sided communication to break into the server. What attacks can you successfully launch against a server using the above technique?
A.Session Hijacking attacks
B.Denial of Service attacks
C.Web page defacement attacks
D.IP spoofing attacks
Correct:A
8.Eric notices repeated probes to port 1080. He learns that the protocol being used is designed to allow a host outside of a firewall to connect transparently and securely through the firewall. He wonders if his firewall has been breached. What would be your inference?
A.Eric's network has been penetrated by a firewall breach
B.The attacker is using the ICMP protocol to have a covert channel
C.Eric has a Wingate package providing FTP redirection on his network
D.Somebody is using SOCKS on the network to communicate through the firewall
Correct:D
9.Mark works as a contractor for the Department of Defense and is in charge of network security. He has spent the last month securing access to his network from all possible entry points. He has segmented his network into several subnets and has installed firewalls all over the network. He has placed very stringent rules on all the firewalls, blocking everything in and out except ports that must be used. He does need to have port 80 open since his company hosts a website that must be accessed from the Internet. Mark is fairly confident of his perimeter defenses, but is still worried about programs like Hping2 that can get into a network through covert channels. How should mark protect his network from an attacker using Hping2 to scan his internal network?
A.Block ICMP type 13 messages
B.Block all incoming traffic on port 53
C.Block all outgoing traffic on port 53
D.Use stateful inspection on the firewalls
Correct:A
10.Bill has started to notice some slowness on his network when trying to update his company's website and while trying to access the website from the Internet. Bill asks the help desk manager if he has received any calls about slowness from the end users, but the help desk manager says that he has not. Bill receives a number of calls from customers that cannot access the company website and cannot purchase anything online. Bill logs on to a couple of his routers and notices that the logs show network traffic is at an all time high.?He also notices that almost all the traffic is originating from a specific address. Bill decides to use Geotrace to find out where the suspect IP is originates from. The Geotrace utility runs a traceroute and finds that the IP is coming from Panama.?Bill knows that none of his customers are in Panama so he immediately thinks that his company is under a Denial of Service attack. Now Bill needs to find out more about the originating IP address. What Internet registry should Bill look in to find the IP address?
A.LACNIC
B.ARIN
C.RIPE LACNIC
D.APNIC
Correct:A
11.Bill has successfully executed a buffer overflow against a Windows IIS web server. He has been able to spawn an interactive shell and plans to deface the main web page. He first attempts to use the "Echo" command to simply overwrite index.html and remains unsuccessful. He then attempts to delete the page and achieves no progress. Finally, he tries to overwrite it with another page in which also he remains unsuccessful. What is the probable cause of Bill's problem?
A.The system is a honeypot
B.The HTML file has permissions of read only
C.You cannot use a buffer overflow to deface a web page
D.There is a problem with the shell and he needs to run the attack again
Correct:B
12.Clive is conducting a pen-test and has just port scanned a system on the network. He has identified the operating system as Linux and been able to elicit responses from ports 23, 25 and 53. He infers port 23 as running Telnet service, port 25 as running SMTP service and port 53 as running DNS service. The client confirms these findings and attests to the current availability of the services. When he tries to telnet to port 23 or 25, he gets a blank screen in response. On typing other commands, he sees only blank spaces or underscores symbols on the screen. What are you most likely to infer from this?
A.The services are protected by TCP wrappers
B.There is a honeypot running on the scanned machine
C.An attacker has replaced the services with trojaned ones
D.This indicates that the telnet and SMTP server have crashed
Correct:A
13.Maurine is working as a security consultant for Hinklemeir Associates.She has asked the Systems Administrator to create a group policy that would not allow null sessions on the network. The Systems Administrator is fresh out of college and has never heard of null sessions and does not know what they are used for. Maurine is trying to explain to the Systems Administrator that hackers will try to create a null session when footprinting the network. Why would an attacker try to create a null session with a computer on a network?
A.Enumerate users and shares
B.Install a backdoor for later attacks
C.Escalate his/her privileges on the target server
D.To create a user with administrative privileges for later use
Correct:A

B.It's a technique used to discover Wireless network on foot
C.It's a technique used to discover interface in promiscuous mode
D.It's a technique used to discover what rules are configured on a gateway
Correct:D
16.Travis works primarily from home as a medical transcriptionist. He just bought a brand new Dual Core Pentium computer with over 3 GB of RAM. He uses voice recognition software to help him transfer what he dictates to electronic documents. The voice recognition software is processor intensive, which is why he bought the new computer. Travis frequently has to get on the Internet to do research on what he is working on. After about two months of working on his new computer, he notices that it is not running nearly as fast as it used to. Travis uses antivirus software, anti-spyware software, and always keeps the computer up-to-date with Microsoft patches. After another month of working on the computer, Travis' computer is even more noticeably slow. Every once in awhile, Travis also notices a window or two pop-up on his screen, but they quickly disappear.He has seen these windows show up, even when he has not been on the Internet. Travis is really worried about his computer because he spent a lot of money on it, and he depends on it to work. Travis scans his computer with all kinds of software, and cannot find anything out of the ordinary. Travis decides to go through Windows Explorer and check out the file system, folder by folder, to see if there is anything he can find. He spends over four hours pouring over the files and folders and cannot find anything.But, before he gives up, he notices that his computer only has about 10 GB of free space available.Since his hard drive is a 200 GB hard drive, Travis thinks this is very odd. Travis downloads Space Monger and adds up the sizes for all the folders and files on his computer. According to his calculations, he should have around 150 GB of free space. What is mostly likely the cause of Travis' problems?
A.Travis's computer is infected with stealth kernel level rootkit
B.Travis's computer is infected with Stealth Trojan Virus
C.Travis's computer is infected with Self-Replication Worm that fills the hard disk space
D.Logic Bomb is triggered at random times creating hidden data consuming junk files
