.Vmdk ကေတာ့ VMware Forensics မွာ အေရးၾကီးတဲ့ အပုိင္းမွာ ပါ၀င္ပါတယ္။ VMware မွာပါ၀င္တဲ့ အခ်က္အလက္ေတြ အကုန္ပါ၀င္ပါတယ္။VMware Hard disk နဲ႕လဲ ခ်ိတ္ဆက္ေပးပါတယ္။
.vmem
.vmem ကေတာ့ ကြန္ပ်ဴတာမွာ အသုံးၿပဳေနတဲ့ Ram ေတြလုိပါပဲ
VMware ရဲ႕ memory ပါ။ ဒါဆုိရင္ အရင္ကေရးခဲ့တဲ့ Memory Forensics
အတုိင္း Forensics လုပ္လုိ႕ရႏုိင္ပါတယ္။ vmem ကေနဘာေတြရႏုိင္မလဲ
User account, Password, Chat history, Web browsing history စတာေတြရရွိႏုိင္ပါတယ္။
.log
Log file မွာေတာ့ Vmware ေပၚမွာ User ၿပဳလုပ္သမွ် action ေတြကုိ ရရွိႏုိင္ပါတယ္။ VM information ေတြလဲရရွိႏုိင္ပါတယ္။ ဒီေလာက္ဆုိဘာေတြ ရႏုိင္မလဲ ဆုိတာသိေလာက္ပါၿပီ။
VMware မွာပါတဲ့ File Type ေတြသာမက က်န္တဲ့ Virtual System ေတြက File Type ေတြကုိလဲ သိထားသင့္ပါတယ္။
How to Forensics ?
Online Forensic Extraction
Offline Forensic Extraction
Simulation နည္းေတြနဲ႕ စစ္ေဆးပါတယ္။
(စစ္ေဆးဖုိ႕အတြက္ စစ္ေဆးသူရဲ႕ ကြ်မ္းက်င္မႈ အၿပင္ ဆက္စပ္အသုံးၿပဳရမဲ့အရာေတြလဲ လုိအပ္ပါတယ္) တစ္ခုေၿပာခ်င္တာကေတာ့ ဘာေတြပဲသုံးသုံး စစ္ေဆးသူရဲ႕ Knowledge က အေရးၾကီးဆုံးေသာေနရာမွာပါ၀င္ပါတယ္ ။
Thanks

NTFS Index Attributes

Image
  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 at...

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 ...
