What is Digital Forensics ? Part (2)

Hypothesis လုိ႕ေခၚတဲ့ ထင္ျမင္ ယူဆခ်က္အေၾကာင္းလာပါျပီး .....
Case တစ္ခုအတြက္ဖမ္းဆီးျပီး သက္ေသခံ Device (Laptop ပဲဆုိၾကပါစုိ႕) ကုိသိမ္းထားလုုိက္ျပီး
ဥပမာ ... ကေလးသူငယ္ပုံေတြကုိတင္ျပီး အြန္လုိင္းကေန လိင္အၾကမ္းဖက္လုပ္ေဆာင္တဲ့အမႈေပါ့ ....
(သိမ္းဆည္းနည္း စစ္ေဆးနည္း အက်ဥ္းကုိ PART 1 မွာေရးျပီးပါျပီး)
လုပ္ေဆာင္တဲ့သူကဒီလူပဲဆုိတာလဲ ေသခ်ာသေလာက္ရွိေနျပီး .... 
laptop ကုိအသုံးျပဳျပီး ပစ္မႈက်ဴးလြန္တယ္လုိ႕လဲယူဆတယ္ ....
ခက္တာက သိမ္းဆည္းမိတဲ့ Laptop က တံခါးျပန္တပ္ ... Sorry ... :)
Window ျပန္တင္ထားတာမၾကာေသးဘူး ..... .... ကဲ ယူဆခ်က္ေတာ့ရွိျပီး သက္ေသခံအခ်က္အလက္ကမရေသးဘူး ...
ကဲ.. ဘာလုပ္မလဲ .... laptop အသုံးျပဳထားတဲ့ Time ... Window ျပန္တင္ထားတဲ့အခ်ိန္ကုိ ၾကည့္မယ္ .... ျပီးရင္ .... Storage Device ျဖစ္တဲ့ Hard Disk ဒါမွမဟုတ္ SSD ေပါ ့ .... အဲဒါေတြရဲ့ Power On Time စစ္မယ္ ... 
HD or SSD ၇ဲ့ Health ကုိစစ္မယ္ .... စစ္ေဆးေနတုန္း... HD ၾကြသြားရင္ လုံး၀အဆင္မေျပႏုိင္ဘူးေလ....
အေရးအၾကီးဆုံးအခ်က္ကေတာ့ ... မူရင္း HD or SSD ကေန Clone ယူျပီး စစ္ေဆးတာ အေကာင္းဆုံး နည္းလမ္းျဖစ္ပါတယ္ ...ဒါမွ သက္ေသခံလဲ မပ်က္စီးပဲ တရားရုံးမွာျပႏုိင္မယ္ ....
အေျခအေနအရ clone ပဲယူယူ .. မူရင္းကုိပဲစစ္စစ္ .... Recovery ေတြ Undelete နည္းလမ္းေတြနဲ႕အဆင္မေျပဘူး ....
ကဲ ... ဘာလုပ္မလဲ ထင္ျမင္ယူဆတာနဲ႕လြဲေနျပီး .... ဒါဆုိရင္ ကုိယ္က ဘယ္လုိနည္းလမ္းေတြအသုံးျပဳျပီးျပီးလဲ ....ေနာက္ထပ္ သိပၸံနည္းက် ဘယ္လုိနည္းလမ္းေတြကုိ အသုံးခ်ျပီး သက္ေသခံရေအာင္ယူမလဲ .... မိမိကြ်မ္းက်င္မႈ အလုိက္အသုံးခ်ရမွာျဖစ္ပါတယ္ .......

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
