To rectify the issue, Jason has to restore the registry. Which of the following utilities can Jason use to accomplish the task? Each correct answer represents a complete solution. Choose all that apply.

Resplendent registrar
Regedit.exe
Reg.exe
EventCombMT

Answer(s): A,B,C

Explanation:

The resplendent registrar is a tool that offers a complete and safe solution to administrators and power users for maintaining the registry. It can be used for maintaining the registry of desktops and remote computers on the network. It offers a solution for backing up and restoring registries, fast background search and replace, adding descriptions to the registry keys, etc. This program is very attractive and easy to use, as it comes in an explorer-style interface. It can be used for Windows 2003/XP/2K/NT/ME/9x.
Reg.exe is a command-line utility that is used to edit the Windows registry. It has the ability to import, export, back up, and restore keys, as well as to compare, modify, and delete keys. It can perform almost all tasks that can be done using the Windows-based Regedit.exe tool.
Registry Editor (REGEDIT) is a registry editing utility that can be used to look at information in the registry. REGEDIT.EXE enables users to search for strings, values, keys, and subkeys and is useful to find a specific value or string. Users can also use REGEDIT.EXE to add, delete, or modify registry entries.
Answer option D is incorrect. EventCombMT is a multithreaded tool that is used to search the event logs of several different computers for specific events, all from one central location. It is a little-known Microsoft tool to run searches for event IDs or text strings against Windows event logs for systems, applications, and security, as well as File Replication Service (FRS), domain name system (DNS), and Active Directory (AD) logs where applicable. The MT stands for multi-threaded. The program is part of the Account Lockout and Management Tools program package for Windows 2000, 2003, and XP.

Which of the following are the valid steps for securing routers? Each correct answer represents a complete solution. Choose all that apply.

Use a password that is easy to remember for a router's administrative console.
Use a complex password for a router's administrative console.
Configure access list entries to prevent unauthorized connections and traffic routing.
Keep routers updated with the latest security patches.

Answer(s): B,C,D

Explanation:

The following are the valid steps for securing routers and devices:
Configure access list entries to prevent unauthorized connections and traffic routing. Use a complex password for a router's administrative console.
Keep routers in locked rooms.
Keep routers updated with the latest security patches.
Use monitoring an equipment to protect routers and devices.
Router is a device that routes data packets between computers in different networks. It is used to connect multiple networks, and it determines the path to be taken by each data packet to its destination computer. Router maintains a routing table of the available routes and their conditions. By using this information, along with distance and cost algorithms, the router determines the best path to be taken by the data packets to the destination computer. A router can connect dissimilar networks, such as Ethernet, FDDI, and Token Ring, and route data packets among them. Routers operate at the network layer (layer 3) of the Open Systems Interconnection (OSI) model.
A security patch is a program that eliminates a vulnerability exploited by hackers.

QUESTION: 172

In which of the following attacks does an attacker successfully insert an intermediary software or program between two communicating hosts?

Session hijacking
Denial-of-Service
Man-in-the-middle
Buffer overflow

Answer(s): C

Explanation:

Man-in-the-middle attacks occur when an attacker successfully inserts an intermediary software or program between two communicating hosts. The intermediary software or program allows attackers to listen to and modify the communication packets passing between the two hosts. The software intercepts the communication packets and then sends the information to the receiving host. The receiving host responds to the software, presuming it to be the legitimate client.
Answer option B is incorrect. A Denial-of-Service (DoS) attack is mounted with the objective of causing a negative impact on the performance of a computer or network. It is also known as a network saturation attack or bandwidth consumption attack. Attackers perform DoS attacks by sending a large number of protocol packets to the network. The effects of a DoS attack are as follows:
Saturates network resources
Disrupts connections between two computers, thereby preventing communications between services Disrupts services to a specific computer
Causes failure to access a Web site
Results in an increase in the amount of spam
A Denial-of-Service attack is very common on the Internet because it is much easier to accomplish. Most of the DoS attacks rely on the weaknesses in the TCP/IP protocol.
Answer option D is incorrect. A buffer-overflow attack is performed when a hacker fills a field, typically an address bar, with more characters than it can accommodate. The excess characters can be run as executable code, effectively giving the hacker control of the computer and overriding any security measures set. There are two main types of buffer overflow attacks:
stack-based buffer overflow attack:
Stack-based buffer overflow attack uses a memory object known as a stack. The hacker develops the code which reserves a specific amount of space for the stack. If the input of user is longer than the amount of space reserved for it within the stack, then the stack will overflow.
heap-based buffer overflow attack:
Heap-based overflow attack floods the memory space reserved for the programs.
Answer option A is incorrect. Session hijacking refers to the exploitation of a valid computer session to gain unauthorized access to information or services in a computer system. In particular, it is used to refer to the theft of a magic cookie used to authenticate a user to a remote server. It has particular relevance to Web developers, as the HTTP cookies used to maintain a session on many Web sites can be easily stolen by an attacker using an intermediary computer or with access to the saved cookies on the victim's computer (see HTTP cookie theft).
TCP session hijacking is when a hacker takes over a TCP session between two machines. Since most uthentication only occurs at the start of a TCP session, this allows the hacker to gain access to a machine.
