Steganography can use image files, audio files, or even video files to contain hidden information. A) True B) False
Steganography is the art of hiding secret information within another non-secret digital media such as image, audio, or video files.
The goal of steganography is to conceal the existence of the hidden message, in such a way that it is difficult to detect or decipher by unintended recipients. Steganography can be a useful tool in situations where confidentiality is required, but encryption may not be enough to protect the data from unauthorized access.
True. Steganography can use different types of files to conceal the secret message, including image files such as JPEG or PNG, audio files such as MP3 or WAV, or even video files such as AVI or MPEG. The process of embedding secret data within these files involves using techniques such as LSB (Least Significant Bit) insertion, where the secret message is embedded within the least significant bits of the data, or spread spectrum modulation, where the secret data is spread across the frequency spectrum of the host data.
The use of steganography is not limited to digital files; it has been used in the past to hide messages in tattoo designs, invisible ink, and even inside hollowed-out books. While steganography can be a powerful tool for hiding information, it can also be used for malicious purposes, such as hiding malware or transmitting illegal or sensitive information.

Which two best practices can mitigate Layer 2 attacks on the network? (Choose two.)A. Disabling STP on all Layer 2 network switches to mitigate ARP attacks.B. Configuring dynamic ARP inspection to mitigate ARP attacks.C. Configuring IP source guard to mitigate CAM and DHCP starvation attacks.D. Disabling DTP on all user access ports to mitigate VLAN hopping.E. Configuring port security on the trunk port to mitigate CAM and DHCP starvation attacks.
The two best practices that can mitigate Layer 2 attacks on the network are: B. Configuring dynamic ARP inspection to mitigate ARP attacks.
Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network to prevent ARP spoofing attacks. DAI intercepts ARP packets on untrusted ports and verifies the MAC address, IP address, and VLAN information against a DHCP snooping database or static configuration. If a packet fails the validation process, it is dropped.
D. Disabling DTP on all user access ports to mitigate VLAN hopping.
Dynamic Trunking Protocol (DTP) is a protocol used to negotiate trunking on a link between two switches. Attackers can exploit DTP to perform VLAN hopping attacks and gain unauthorized access to different VLANs. Disabling DTP on all user access ports can prevent these types of attacks.
The other options are incorrect because:
A. Disabling STP on all Layer 2 network switches to mitigate ARP attacks: Disabling Spanning Tree Protocol (STP) on switches can cause network loops and disrupt network operations. It is not a recommended practice to mitigate ARP attacks.
C. Configuring IP source guard to mitigate CAM and DHCP starvation attacks: IP Source Guard is a feature that validates the source IP address of packets to prevent IP spoofing attacks. It is not directly related to mitigating CAM and DHCP starvation attacks.
E. Configuring port security on the trunk port to mitigate CAM and DHCP starvation attacks: Port security is a feature that limits the number of MAC addresses that can be learned on a port. It is not directly related to mitigating CAM and DHCP starvation attacks.

Which of the following best describes the function of the TTL/Hop limit for IP packages? a. To specify the destination IP address b. To indicate the type of service requested c. To specify the number of routers that the package can pass through before being discarded d. To ensure that the package is delivered in the correct order
The function of the TTL/Hop limit for IP packages is c. to specify the number of routers that the package can pass through before being discarded. TTL stands for Time To Live and it is a value set in the header of the IP packet.
It is decremented by one at each router hop, and when it reaches zero, the packet is discarded and an error message is sent back to the sender. This mechanism helps prevent packets from circulating endlessly in the network and taking up resources. The TTL/Hop limit is not used to specify the destination IP address, which is already included in the packet header. It is also not used to indicate the type of service requested or to ensure that the package is delivered in the correct order. These functions are performed by other fields in the IP packet header. In summary, the TTL/Hop limit for IP packages is a crucial parameter that helps manage network traffic and prevent congestion. It ensures that packets do not travel too far and that they are delivered in a timely and efficient manner. As such, it is an important concept for network administrators and anyone working with network protocols to understand.

B. It performs an arp broadcast only on the destination network to learn the MAC address of the destination computer
C. It sends the packet
D. It queries all other routers for the MAC address of the destination computer
Once a router determines the interface to which it should send a packet, the next step is to send the packet to the next hop or destination. The router uses the routing table to determine the next hop based on the destination IP address of the packet.
Option A is partially correct as ARP broadcast is used to learn the MAC address of the destination device, but it is not performed on all networks. ARP broadcast is sent only on the local network to which the router is connected.
Option B is incorrect because the router does not perform ARP broadcast on the destination network. The router only sends the packet to the next hop based on the information in the routing table.
Option C is correct as sending the packet is the next step after determining the next hop.
Option D is incorrect as the router does not query other routers for the MAC address of the destination computer. ARP broadcast is used to learn the MAC address of the destination device on the local network.
In conclusion, the correct answer is C - the router sends the packet. It is essential to understand the process of packet forwarding in computer networks and how routers play a crucial role in it.

Configuring a Central Store of ADMX files help solve the problem of ________ A) excessive REQ_QWORD registry entries on every workstation B) replication time for copying policies C )Windows 7 workstations not able to receive policies D)"SYSVOL bloat"
Configuring a Central Store of ADMX files can help solve the problem of "SYSVOL bloat" which is the excessive growth of the SYSVOL folder that occurs when Group Policy settings are stored on domain controllers. This issue can lead to replication problems and slow logon times for users.
By creating a Central Store, you can store all your ADMX files in a single location and make them available to all domain controllers. This eliminates the need to store multiple copies of the same files on each domain controller, which can contribute to the growth of the SYSVOL folder.
Furthermore, configuring a Central Store can also help reduce replication time for copying policies. When you make changes to Group Policy settings, those changes must be replicated across all domain controllers. If each domain controller has its own copy of the ADMX files, it can take longer for the changes to propagate. By storing the ADMX files in a Central Store, the changes only need to be replicated to that single location, which can save time and reduce network traffic.
Finally, having a Central Store can also help ensure that Windows 7 workstations are able to receive policies. ADMX files were introduced in Windows Vista and later versions of Windows, but Windows 7 workstations may not be able to read the files if they are stored in their default location. By creating a Central Store and storing the ADMX files there, you can ensure that all workstations can access the latest policies and settings.

(T/F) if port 20 is available, then an attacker can assume that ftp is being used.
True. Port 20 is commonly used by FTP (File Transfer Protocol) for data transfer, while port 21 is used for control information.
if port 20 is open and available for use, it can be assumed that FTP is being used for data transfer. However, it is important to note that the use of port 20 is not exclusive to FTP, and other protocols or applications may use this port for different purposes. Additionally, some FTP servers may be configured to use a different data transfer port, so it is not always a reliable indicator of FTP usage.
