1. For Linux/Unix systems that support SSH, what is the best practice recommendation for credentialed scan authentication?

OAuth authentication

SSH public key authentication with a passphrase

SecurID

Username / password

2. What is the difference between a host discovery scan and a basic network scan?

The network scan discovers hosts, services, and vulnerabilities, whereas the host discovery scan only discovers hosts and services running on open ports

The basic network scan requires credentials

The basic network scan will identify cloud services in use

The host discovery scan requires SecurityCenter to see all network traffic

3. The ‘List OS’ analysis tool shows:

A list of operating systems which SecurityCenter can detect

A list of the top 10 operating systems detected on the network

A list of operating systems and the number of vulnerabilities found

Only operating systems with at least 1 critical vulnerability

4. Using an SNMP community string for login is an example of:

Privilege escalation

SNMP community strings are not supported

Two-factor authentication

Keypair authentication

Compliance auditing is:

Only required by organizations in the government, financial, and industrial sectors

For organizations subject to PCI requirements

Comparing scan results with an established standard and reporting the deviations

Comparing scan results to trending vulnerabilities

Before a user adds a scan, which of the following would have been created (usually by another user, e.g., admin):

Scan Zones

Repositories

All of these

None of these

Which of the following is a valid post scan option?

Email the user who created the scan for each critical or high vulnerability that is found

Run a report

If the scan times out and does not complete, discard all results and restart the scan

Remove vulnerabilities from scanned hosts that do not reply

Which are the two types of Assurance Report Card?

Compliance or Executive

Vulnerability or Event

Executive or CIO

None of the these

The definitions of individual scan, cumulative, and mitigated vulnerability analysis do NOT include:

A single scan’s results, useful to show point-in time data

Alerting based on vulnerability results

Allows the user to filter results based on when the vulnerability was mitigated

Current vulnerabilities, including those recast, accepted or mitigated

On Windows hosts, the following is NOT a requirement for credentialed scans:

The authentication method must be set to classic

WMI service must be running and either set to a static port, or all ports must be opened between the Nessus scanner and the target host

All of these are required

The remote registry service must be disabled

File and print sharing must be enabled

hich of the following can be used for credentialed scans in SecurityCenter?

Encrypted username and password

All of these

Clear text username and password

RSA/DSA key pairs

Before performing scan analysis, the following is required:

Credentialed scans of all target systems

Active scan data and access to the repository containing the data

Passive AND Active scan data, as well as access to the repository containing the data

Queries created based upon the data you wish to analyze

After configuring vulnerability or event filters as desired, you can save your result as a:

Filtered Results List

Query

None of these

Saved Vulnerability List

Analyzing cumulative data is useful:

To view vulnerabilities that have been remediated

To extract point-in-time information with a narrow focus

To view trending information

To understand the full exposure of the network

ARCs can assist in checking for compliance with which of the following?

Internal policies

Business objectives

All of these

Industry/Government compliance requirements

Configuration recommendations that are typical for a secure baseline configuration from which to gauge compliance include all of the following except:

Listening service configuration

Sensitive data

Age of system hardware

Password complexity

System logging

The components required for each scan within SecurityCenter are:

Name, scan zone, repository, credentials, and targets

Schedule, asset, targets, and a post-scan report

Name, scan policy, scan zone, repository, and targets

Credentials, audit checks, repository, scan zone, and targets

Which of these is a valid scan target definition?

10.0.0.1-10.0.10.100

10.0.0.0/16

10.0.0.1,10.0.0.3

All of these

Why would you NOT want to store credentialed and non-credentialed data in the same repository?

Exporting the data will take too long

Mitigation information may be inaccurate

You can’t report on the data

If exported, you can’t import the data

When scanning a database, Tenable recommends that you:

Scan any other applications running on the database server

All of these

Scan the database software

Scan the operating system of the database server

When evaluating compliance scan results, you should want to focus on:

Compliant systems

Deviant systems

All of these

Offline systems

Vulnerabilities can be analyzed either as:

Mitigated or Resolved

Cumulative or Mitigated

Active or Transient

Active or Completed

Regarding ARCs in SecurityCenter, what does “CCC” stand for?

Cyber Common Controls

Common Cyber Controls

Critical Cyber Controls

Cyber Critical Controls

The types of repositories are:

Local, Remote, and Custom

IPv4, IPv6, Mobile, External, and Offline

Local, Cloud, and Offline

Compliance, Vulnerability, and Network

Scan policies can be created from:

Pre-configured template

Customized new template based on internal policies

All of these

Existing template

Compliance results use Info, High, and Medium severities to indicate:

Warning, Fail, and Contact Support

Fail, Pass, and Unable to complete the check

Pass, Fail, and Unable to complete the check

Which of the following is true about a scan in SecurityCenter?

It must contain a scan policy

All of these

It can be restricted to specific targets

It can be scheduled to run

Why is it advisable to assign scanners to scan zones based on network topology?

It is not advisable since SecurityCenter will assign scanners on the fly

To avoid scanning offline systems

To avoid issues created by scanning through firewalls

To allow SecurityCenter to accurately update plugins on remote scanners

When on the ‘Add Active Scan’ page, if “Automatic Distribution Only” is set for the Organization’s scanning distribution method by the admin, the scanner used will be:

SecurityCenter picks the first available scanner, regardless where it is located in relation to the targets

None of these

SecurityCenter uses all available scanners and distributes the load

SecurityCenter picks the best available scanner in the target's scan zone

SecurityCenter uses the scanner set as “default” during the initial configuration

If you are performing network and credentialed scans against the same targets, you should ___________ to ensure accurate mitigation data.

Create separate repositories to store each type of scan data

Configure SecurityCenter to discard all network scan data

Scan them using different user accounts

Create a separate organization
