Security+ Network Security Fundamentals Chapter 7 – Flashcards

The OSI model breaks networking steps down into a series of six layers.

Behavior-based monitoring attempts to overcome the limitations of both anomaly-based monitoring and signature-based monitoring by being more adaptive and proactive instead of reactive.

Security is enhanced by subnetting a single network into multiple smaller subnets in order to isolate groups of hosts.

Workgroup switches must work faster than core switches.

Defense in depth, or layered security, involves the use of multiple types of network hardware within a network.​

What layer of the OSI model is responsible for permitting two parties on a network to hold ongoing communications across the network?

Select below the layer of the OSI model at which the route a packet is to take is determined, and the addressing of the packet is performed.

An early networking device that functioned at layer 1 of the OSI model and added devices to a single segment is known as which of the following choices?

What kind of networking device forwards packets across different computer networks by reading destination addresses?

An administrator has two servers that host the same web content, but only one server is utilized at a given time. What can be configured to make use of both servers in a manner that is transparent to the end users?

A firewall that keeps a record of the state of a connection between an internal computer and an external device is using what technology below?

What is the name for a computer or application program that intercepts user requests from the internal secure network and then processes that request on behalf of the user?

A server that routes incoming requests to a specific destination server, and acts as the final destination IP for all client access, is known as a:

What technology enables authorized users to use an unsecured public network, such as the Internet, as if were a secure private network?

Select below the technology that can be used to examine content through application-level filtering:

What type of monitoring compares network traffic, activities, transactions, or behavior against a database of known attack patterns?

What is the name for an instruction that interrupts a program being executed and requests a service from the operating system?

When a private network uses a single public IP address, and each outgoing TCP packet uses a different port to allow for proper translation, what networking technology is in use?

Which network address below is not a private IP address network?

A web server must be accessible to untrusted outside users. What can be done to isolate this host and any additional hosts with similar requirements from more secured hosts on a network?

The standard TCP/IP protocol uses IP addresses which are how many bytes in length?

What vendor neutral protocol implements support for VLAN tagging?

The management in your corporate office want to group users on the network together logically even though they are attached to separate network switches. How can this be done?

​Which of the following is not a component of an IP packet that a firewall rule can use for filtering purposes?

A load balancer that works with the File Transfer Protocol is operating at what layer of the OSI model?

Internet ____________________ filters monitor Internet traffic and block access to pre-selected Web sites and files.

_________________ is a technique that allows a private IP addresses to be used on the Internet with a single public IP address.

A network _________________ isolates connected devices by learning MAC addresses and only sending frames intended for specific MAC addresses to the ports they're connected to, unless the MAC address is unknown.

A ______________ is a worker who work occasionally or regularly from a home office.

The traffic sent by devices connected to a hub can be captured and decoded by a _________________.
