What can you do to prove that the evidence is the same as it was when it first entered the lab?

make an MD5 hash of the evidence and compare it with the original MD5 hash that was taken when the evidence first entered the lab
make an MD5 hash of the evidence and compare it to the standard database developed by NIST
there is no reason to worry about this possible claim because state labs are certified

Precautionary measures to prevent this attack would include writing firewall rules. Of these firewall rules, which among the following would be appropriate?

Disallow UDP53 in from outside to DNS server
Allow UDP53 in from DNS server to outside
Disallow TCP53 in from secondaries or ISP server to DNS server
Block all UDP traffic

Correct answer: A

When monitoring for both intrusion and security events between multiple computers, it is essential that the computers' clocks are synchronized. Synchronized time allows an administrator to reconstruct what took place during an attack against multiple computers. Without synchronized time, it is very difficult to determine exactly when specific events took place, and how events interlace. What is the name of the service used to synchronize time among multiple computers?

Universal Time Set
Network Time Protocol
SyncTime Service
Time-Sync Protocol

Correct answer: B
