What technology allows a user to access the Internet through the wiring of a home?

Cable Internet access

Cable Internet provides access using a cable modem on hybrid fiber coaxial wiring originally developed to carry television signals. Either fiber-optic or coaxial copper cable may connect a node to a customer’s location at a connection known as a cable drop.

Which secured tunneling protocol might be able to cross firewalls where IPsec is blocked?

Which secured tunneling protocol might be able to cross firewalls where IPsec is blocked? – OpenVPN, is an open-source VPN protocol that uses a custom security protocol called OpenSSL for encryption. OpenVPN has the ability to cross many firewalls where IPsec might be blocked.

What is the purpose of network-attached storage devices?

Network-attached storage (NAS) is dedicated file storage that enables multiple users and heterogeneous client devices to retrieve data from centralized disk capacity. Users on a local area network (LAN) access the shared storage via a standard Ethernet connection.

What functions does a network-attached storage PC provide?

Network-attached storage removes the responsibility of file serving from other servers on the network. They typically provide access to files using network file sharing protocols. In CCTV, NAS devices have gained popularity, as a convenient method of sharing files among multiple computers.

👉 Discover more in this in-depth guide.

What protocols are used by network-attached storage?

NAS uses file-based protocols such as NFS (popular on UNIX systems), SMB (Server Message Block) (used with MS Windows systems), AFP (used with Apple Macintosh computers), or NCP (used with OES and Novell NetWare). NAS units rarely limit clients to a single protocol.

What are the two primary encryption techniques used by VPNS today?

SSL and TLS are both methods of encrypting TCP/IP transmissions en route between the client and server using public key encryption technology. The two protocols work together and are widely known as SSL/TLS.

Which of the following suggestions can help prevent VLAN hopping attacks on a network?

aaaaaaaaaa borger

Question	Answer
Which of the following suggestions can help prevent VLAN hopping attacks on a network?	Disable auto trunking and move native VLANs to unused VLANs.
With VTP, where is the VLAN database stored?	On the switch that is known as the stack master.

What are the two primary encryption techniques used by VPN?

Types of VPN encryption

Symmetric-key. This is where the key for encryption and decryption is the same, and both communicating parties must possess the same key in order to communicate. …
Public-key. …
Handshake encryption (RSA) …
Secure Hash Algorithm (SHA) …
SSL and TLS. …
OpenVPN. …
IKEv2/IPsec. …
L2TP/IPsec.

When should IPsec be used?

IPsec is used for protecting sensitive data, such as financial transactions, medical records and corporate communications, as it’s transmitted across the network. It’s also used to secure virtual private networks (VPNs), where IPsec tunneling encrypts all data sent between two endpoints.

Does IPsec require network applications to be IPsec aware?

IPsec requires network applications to be IPsec aware. IPsec encrypts data. IPsec adds overhead for all network communications for which it is used. … A honey pot is an appliance or piece of software that allows or denies network access based on a preconfigured set of rules.

How is IPsec used?

IPsec is a group of protocols that are used together to set up encrypted connections between devices. It helps keep data sent over public networks secure. IPsec is often used to set up VPNs, and it works by encrypting IP packets, along with authenticating the source where the packets come from.

At what layer of the OSI model does a network switch normally operate?

Data Link layer

A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach.

When Windows Server controls network access to a group of computers this logical group is called which of the following?

Terms in this set (60) When Windows Server controls network access to a group of computers, this is a domain. The centralized directory database that contains user account information and security for the entire group of computers in a network.

At which layer of the OSI model does a standard network switch operate group of answer choices?

Network switches can operate at either OSI layer 2 (the data link layer) or layer 3 (the network layer). Layer 2 switches forward data based on the destination MAC address (see below for definition), while layer 3 switches forward data based on the destination IP address. Some switches can do both.

At which layer of the OSI network model does IPsec work?

network layer

The IPsec protocol suite operates at the network layer of the OSI model. It runs directly on top of IP (the Internet Protocol), which is responsible for routing data packets. Meanwhile, SSL operates at the application layer of the OSI model.

At what layer of the OSI model does the IPsec and TLS encryption protocol operate?

As a part of the IPv4 enhancement, IPsec is a layer 3 OSI model or internet layer end-to-end security scheme.

At which layer of the OSI model does VPN Virtual Private Network operate?

VPNs can be designed based on communication taking place on Layer 3, the net- work layer, in the Open Systems Interconnection model (OSI model), or on Layer 4, the transport layer. OSI is a conceptual model that shows how various computer systems can commu- nicate with one another.

Why is Nmap useful?

Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.

Why should you use Nmap?

At its core, Nmap is a network scanning tool that uses IP packets to identify all the devices connected to a network and to provide information on the services and operating systems they are running. … Nmap was developed for enterprise-scale networks and can scan through thousands of connected devices.

What is the purpose of Nmap?

Using Nmap

Nmap allows you to scan your network and discover not only everything connected to it, but also a wide variety of information about what’s connected, what services each host is operating, and so on. It allows a large number of scanning techniques, such as UDP, TCP connect (), TCP SYN (half-open), and FTP.
