What is Cyber forensics ? Part (21)
Memory forensics
Ram ဆုိတာ ဘာျဖစ္တယ္ ဘာလုပ္တယ္ဆုိတာေတာ့ အခု post မွာ
မေျပာေတာ့ပါဘူး ...
ကြန္ပ်ဴတာ Power Off တာနဲ႕ Ram ထဲမွာ သိမ္းဆည္းထားတဲ့ Information ေတြပ်က္စီးသြားပါတယ္ ..
Ram ကေနဘာေတြရႏုိင္မလဲ
End point Security (antivirus) အခ်ဳိ႕က Ram ကုိတုိက္ရုိက္ထိခုိက္ေစတဲ့ Virus မ်ဳိးကုိ မစစ္ေဆးႏုိင္ၾကပါဘူး ဒါေၾကာင့္ malware Forensics လုပ္တဲ့အခ်ိန္မွာ အသုံး၀င္ပါတယ္
Computer စဖြင့္တဲ့အခ်ိန္မွာ ရုိက္လုိက္တဲ့ username password , Browser History , Internet Connection LAN,Wireless (IP address DNS) ,Open Port, Some chat message အစရွိသည္ျဖင့္ ရရွိႏုိင္ပါသည္။
Memory Forensics ျပဳလုပ္ရမည့္အခ်ိန္ကေတာ့ computer On ေနတဲ့အေနအထားမွာျပဳလုပ္ရမွာ ျဖစ္ပါတယ္.. Computer ရဲ႕ ram ပမာဏအေပၚမူတည္ၿပီး Memory Dump File Size ရရွိမွာျဖစ္ပါတယ္ ။အခု ကြ်န္ေတာ္စက္ဆုိ 16 GB ရွိတဲ့အတြက္ dunp file က 16 GB ရရွိပါတယ္။
အခုအသုံးျပဳထားတာေတာ့ Magnet Memory Forensic နဲ႕ Magnet IEF တုိ႔ ျဖစ္ပါတယ္။
ပုံေတြမွာ evidence ေတြကေတာ့ နမူနာပဲျပထားျခင္းျဖစ္ပါသည္။ ကုိယ့္ PC ကုိပဲစမ္းစပ္ထားျခင္းျဖစ္ပါသည္။ Result ထုတ္ေနတုန္းေရးထားတာေၾကာင့္ပါ။

B-Trees (NTFS)

Image
  B-Trees An NTFS index sort attributes into a tree, specifically a B-tree. A tree is a group of data structures called nodes that are linked together such that there is a head node and its branches out to the other nodes. Consider Figure 11.13(A), where we see node A on top and it links to nodes B and C. Node B links to nodes D and E. A parent node is one that links to other nodes, and a child node is one that is linked to. For example, A is a parent node to B and C, which are children of A. A leaf node is one that has no links from it. Nodes C, D, and E are leaves. The example shown is a binary tree because there are a maximum of two children per node. Figure 11.13. Examples of A) a tree with 5 nodes and B) the same tree that is sorted by the node values FIG- 11.3 Trees are useful because they can be used to easily sort and find data. Figure 11.13(B) shows the same tree as we saw on the left side, but now with values that are assigned to each node. If we are trying to look up a valu

NTFS Index Attributes

  NTFS Index Attributes Now that we have described the general concept of B-trees, we need to describe how they are implemented in NTFS to create indexes. Each entry in the tree uses a data structure called an index entry to store the values in each node. There are many types of index entries, but they all have the same standard header fields, which are given in Chapter 13. For example, a directory index entry contains a few header values and a $FILE_NAME attribute. The index entries are organized into nodes of the tree and stored in a list. An empty entry is used to signal the end of the list. Figure 11.18 shows an example of a node in a directory index with four $FILE_NAME index entries. Figure 11.18. A node in an NTFS directory index tree with four index entries. Figure 11.18 The index nodes can be stored in two types of MFT entry attributes. The $INDEX_ROOT attribute is always resident and can store only one node that contains a small number of index entries. The $INDEX_ROOT attrib
