DNS Cache Poisoning

One way to misdirect a host, is DNS cache poisoning. The DNS cache stores IP addresses of websites recently resolved. It is possible for a hacker to insert fake mappings into DNS server by using buffer overflow or other means. The SOA record tells how long the DNS cache poisoning will last. In order to make the DNS server secure from the DNS cache poisoning attack, enable DNS socket pool on the DNS server. The socket pool makes cache poisoning attacks more difficult because an attacker must correctly guess the source port of a DNS query in addition to a random transaction ID to successfully execute the attack. The DNS socket pool enables a DNS server to use source port randomization when issuing DNS queries. This provides enhanced security against cache poisoning attacks.

Which file system runs on NTFS?

Windows

Which statements are true regarding EFS? - EFS can encrypt files stored on Windows 2000, Windows XP Pro, and Windows Server 2003 - EFT protects data in transit - EFS uses symmetric and asymmetric cryptography

YES! EFS encyrpts files stored on Windows 2000, XP Pro and Server 2003. It is NOT designed to protect data in transit from one system to another. EFS uses symmetric and asymmetric cryptography. EFS encyryption occurs at the file system level not the application level. It is transparent to the user and to the application. If a folder marked for encryption, then every file created in or moved to said folder will be encrypted. There is no back door. File encryption uses a symmetric key. This symmetric key is then encrypted with an asymmetric public key. EFS keys are protected by the user's password EFS-encrypted files do not remain encrypted during transport if saved to or opened from a folder on a remote server. The file is decrypted, traverses the network in plaintext and if saved to a folder with encryption, re-encrypted.

While swap space can help machines with a small amount of RAM, it should not be considered a replacement for more RAM. The name of this file is the pagefile.sys (Swap file where evidence from RAM can be located) and is located in the root of the C:\."

Frye Standard

"The net use command is used to display information about shared resources on the network that you're currently connected to, as well as open sessions on other systems."

Lost Cluster

"The operating system assigns a unique number to each cluster and then keeps track of files according to which clusters they use. Occasionally, the operating system marks a cluster as being used even though it is not assigned to any file. This is called a lost cluster."

Slack Space

"The unused space in a disk cluster. The DOS and Windows file systems use fixed-size clusters. Even if the actual data being stored requires less storage than the cluster size, an entire cluster is reserved for the file. The unused space is called the slack space"

Logical block addressing (LBA):

"is a common scheme used for specifying the location of blocks of data stored on computer storage devices, generally secondary storage systems such as hard disks. LBA is a particularly simple linear addressing scheme; blocks are located by an integer index, with the first block being LBA 0, the second LBA 1, and so on in a sequential matter."

DNS Poisoning: DNS spoofing (or DNS cache poisoning)

"is a computer hacking attack, whereby data is introduced into a Domain Name System (DNS) resolver's cache, causing the name server to return an incorrect IP address, diverting traffic to the attacker's computer (or any other computer)."

Address Resolution Protocol (ARP) Spoofing

ARP spoofing is also known as ARP cache poisoning or ARP poison routing. It is a technique used to attack a local-area network. ARP spoofing can allow an attacker to intercept data and modify or halt network traffic. ARP spoofing can be used to attack an Ethernet wired or wireless network. During normal functioning, ARP sends a broadcast with the IP address asking for the associated MAC address. A host having said IP address replies with its MAC address. Thus the ARP cache gains an entry matching IP address with MAC address. During ARP spoofing or ARP poisoning, ARP sends the same broadcast but an attacker replies with fake MAC address. Now the ARP cache has a false entry and all communication from the host will go to the fake MAC address One defense against ARP spoofing is placing static ARP entries on servers, workstations, and routers using the ARPWALL system.
