Incident Handling Process 6 steps (Preparation, Identification, Containment, Eradication,Recovery, Lessons Leaned) B. What is incident handling? An action plan for dealing with the misuse of a computer systemsand network. C. What is an event? Any observable occurrence in a system and / or network. D. What is an incident? Is an adverse event in an information system / and or network.1. Preparation Page 152. Identification Page 46- Cheat sheets: Page 583. Containment Page 924. Eradication Page 1115. Recovery Page 1176.

Linux Page 223 SANS GCIH CERTIFICATION GUIDE:BOOK 504.2Trends : 1. Hacktivism: Page 11 3. Software Distro Site Attacks Page 13-14 2. Attack for fun and profit: Page 12 4. The Golden Age Page 15 Reconnaissance :1. Domain Name Registration (Address, Phone, Contacts, Authoritative DNS) Page 19a. Useful for SE, War Dialing and scanning2. Whois : Allows you get information on domains and IP. Including nameservers Page 20-21a. Defense is to just deal with it.b. Identification impossible3. DNS interrogation : Uses information from a whois to pull additional info. Page 26-30a. Defense : Use split DNS (internal and external), limit zone transfers, harden serversb. Identification : look for zone transfers4. Web Site Searches : Search targets site, search job sites, search partner sites, search social mediasites, blogs and newspapers. Press releases, contacts, design docs and so on Page 32-35a. Defense: limit what is posted, generalize job openings, and protect directories fromcrawlers.b. Identification: Search for crawler traffic and mass site downloads5. Google : Johnny Long and GHDB. Use to find vulnerabilities Page 37-48i. Defense : robots.txt (NOINDEX, NOFOLLOW, NOSNIPPET, NOARCHIVE) removalof content and re-crawl site google.com/addurl.html . Conduct self searches.b. Phonebook searches (phonebook: and REVERSE:). Removal /help/pbremoval.htmlc. Google Maps (View physical security of a building, roads, doors & so on.d. Search directives:i. site, link, intitle, inurl, info, cache, filetype and ext (the same, better to just usedoc, pdf & so on), (-) and word (+) and word (.) wild card for a single charactere. Automated Google w/ Key : Site digger and Wikto / Without Goolag, Wikto w/ AURA &SecApp GHDB6. Maltego : intelligence gathering tool by, maps relationships using transforms Page 50-52a. Defense : make sure your data is accurate and scan yourself. Ask that inaccurate /damaging data be removed.7. War Dialers : dials number looking for modems and secondary dial tone. Page 56-64a. THC Scan (newest version can be sued on botnet)b. Warvox: Uses voip accounts can do 1,000 numbers an hour, spoof caller ID and call asself.c. Use the results to try to access systems 8. War Driving / wireless: Page 66-81a. Netstumbler : limited driver support, relies on SSID, Active, GPS tie in.b. Wellenreiter : Passive scanning, packet capture, IP gathering, Linuxc. Cracking & Sniffing: Kismet, ominpeek, aircrak-ng, wepCrack, ASLEAP, CowPatty d. Karma: pretends to be everything, responds to all probe requests, allows you to act asrequested resource can be tied into metasploit. e. Defense: WPA or better, mac address filtering, Non attractive SSID or no SSID, use a vpntunnel, better placement of AP, look for rouge devices, wireless IPS / IDS (ARUBA,Motorola) 9. Network Mapping / Nmap: Tracert, traceroute and nmap, zenmap gui Page 85-94 a. IP Headet: TTL, SRC IP and DST IP b. Traceroute: Uses low TTL and ICMP time exceed message to map. Increases each by 1after a time exceed till it hits host. c. Nmap: Now uses PN (NO PING), Sends 4 packets to check if host is up ICMP ECHORequest, ICMP Timestamp request, TCP SYN to port 443 and TCP ACK to 80 if running asUID 0 or if not then syn. i. More efficient mapping of larger networks using. Starts with large TTL and willadjust till it find the correct TTL and then starts counting backwards. d. Zenmap: Visual Graphing of the network map based on the results from nmap. e. Defense: Disable incoming ICMP echo requests and outbound time exceeded. 10. Port Scanning/ Active OS : Nmap, Xprob2 Page 95-120a. Nmap scan type Page 101b. Namp IP Spoofing and Idle Scan: IP Identification field, predictable Page 105-108c. Active OS Finger printing Page 111-113d. Tools: netstat, fport, wmic, sc, netstat and checkconfig Page 115-119e. Defense: turn off service not needed, stateful firewall and proxy, IPS/ IDS, Change OSidentification info.11. Passive OS : P0F2: Uses a sniffer and database for matching, defense above Page 126-12812. Firewalk allows you to determine what ports are open on a firewall Page 130-13613. Fragmentation Attacks : breaking up a packet to bypass IDS Page 137-145a. Tiny fragmentationb. Overlapping fragmentation14. Fragrouter & Fragroute: tools too fragment packets and bypass IDS/IPS Page 146-148a. Defense: reassemble packets before IPS ?IDS, host based IPS/ IDS, Keep up to date,make sure your IPS/IDS properly speced.15. Vulnerability Scanning: Nessus, SATAN and so on, mostly NESSUS info Page 151-16416. Web: CGI, PHP, JSP, ASP: Nikto scanner, Whisker, IDS Invasion Page 165-178a. GET Request: passing parameters values on the urlb. POST Request: passing parameters in the bodyc. Defense: Run server with least privilege, Remove default scripts and directories, Patchand harden, Good code (scrub bad parameters) 17. Null Sessions: Enum, net use, net view, winfingerprint, smbclient Page 179-210
