Security – Chapter 6

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

False

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.

True

All modern operating systems include a hardware firewall, usually called a host-based firewall

False

Workgroup switches must work faster than core switches.

False

An intranet is a separate open network that anyone can access without prior authorization.

False

NAT is not a specific device, technology, or protocol. It is a technique for substituting IP addresses.

True

A security advantage of VLANs is that they can be used to prevent direct communication between servers.

True

An agent may be a permanent NAC agent and reside on end devices until uninstalled, but it cannot be a dissolvable NAC agent

False

One use of data loss prevention (DLP) is blocking the copying of files to a USB flash drive.

True

Anomaly monitoring is designed for detecting statistical anomalies

True

What data unit is associated with the Open Systems Interconnection layer two?

C. Frame

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

B. Router

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 that can help to evenly distribute work across the network, and make use of both servers in a manner that is transparent to the end users?

B. Load Balancing

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?

C. Stateful Packet filtering

What is the name of 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. Forward Proxy server

Which of the following is a server that routes incoming requests coming from an external network to the correct internal server?

D. reverse proxy

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

B. VPN

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

C. Web security gateway

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

D. Signature-based

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

A. System call

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?

A. PAT

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

B. 172.63.255.0

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?

C. Create a DMZ, add necessary hosts.

What vendor neutral protocol implements support for VLAN tagging?

C. 802.1Q

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

D. Create a VLAN and add the users’ computers / ports to the correct VLAN

What technology will examine the current state of a network device before allowing it can to connect to the network and force any device that does not meet a specified set of criteria to connect only to a quarantine network?

A. Network access control

What type of dedicated cryptographic processor that provides protection for cryptographic keys?

D. Hardware security module

Which of the following is a software-based application that runs on a local host computer that can detect an attack as it occurs?

B. host-based intrusion detection system

When VPN network traffic is routing only some traffic over the secure VPN while other traffic directly accesses the Internet, what technology is being used?

B. Split tunneling

What dedicated hardware device aggregates hundreds or thousands of VPN connections?

D. VPN concentrator

What specific type of hardware card inserts into a web server that contains one or more co-processors to handle SSL/TLS processing?

A. SSL/TLS accelerator

What type of network is a private network that belongs to an organization that can only be accessed by approved internal users?

B. Intranet

What type of network is a private network that can also be accessed by authorized external customers, vendors, and partners?

A. Extranet

If a network is completely isolated by an air gap from all other outside networks it is using what type of configuration?

physical network segregation

What term is used to describe the software agents that are used by NAC and installed on devices to gather information?

C. Host agent health checks

What type of network access control uses Active Directory to scan a device to verify that it is in compliance?

A. agentless NAC

Which of the following is defined as a security analysis of the transaction within its approved context?

B. Content inspection

Which of the following is a system of security tools that are used to recognize and identify data that is critical to the organization and ensure that it is protected?

D. data loss prevention
