CISSP Chapter 6 Ted
An application has been written where two processes are running at the same time. For process A to calculate properly, it needs data from process B. If process A calculates before process B completes, this is an example of which condition? A. Race condition B. Buffer overflow C. Process exhaustion D. Application development
Answer: A A buffer overflow attacks memory due to poor coding and allows the attacker to control the process. Process exhaustion occurs when a process hangs because it has run out of resources. Application development is basic computer coding and is not a negative condition.
Which of the following is NOT a software tool that analyzes source code for bugs and security vulnerabilities? A. Compiler B. SonarQube C. WhiteSource D. Veracode
Answer: A A compiler converts source code into machine language and can find coding syntax errors. SonarQube, WhiteSource, and Veracode search for security vulnerabilities, poorly written libraries, and licensing-related issues to keep the source code accurate and consistent.
You can monitor a website's storage, users, and system loads for effectiveness with which of the following utilities? A. Alerts and logs B. Events and logs C. Metrics and logs D. Thresholds and logs
Answer: A Alerts use thresholds and metrics to immediately inform administrators that a system requires attention. Events are entries that go into log files.
What is a key problem with getting too many false positives and false negatives on a system? A. Alerts eventually get ignored. B. Such systems will not pass NIST standards for compliance. C. The system is functional but requires extra attention. D. The system is about to fail.
Answer: A All alerts, including true alerts, can eventually be ignored. The other options are not true because getting false alerts is common across common systems.
Tobin is a security manager and has learned that a new software management application has been introduced to the company. Staff are excited to use it because it will double production at half the cost of past methods. What is her BEST recommendation? A. Test the software for vulnerabilities before rolling into production. B. Because of past user testimonials, roll the application into production immediately. C. Because of user demand, roll the application into production immediately. D. Because of financial pressures, roll the application into production immediately.
Answer: A Applications must be tested and baselined before they are rolled into production; otherwise, the results may be a lot worse than a few unhappy users; for example, a financial shortfall.
Level one merchants are required to conduct network scans how often to comply with PCI-DSS? A. Quarterly scans by an Approved Scanning Vendor (ASV) B. Bi-annual scans by internal auditors C. Annual scans by internal auditors D. Annual scans by an ASV
Answer: A Approved scanning vendors (ASVs) are required to run penetration and internal scans, and then report the results to their acquiring financial institution. Level 1 merchants process more than 6 million credit card transactions annually, so they are desirable targets for hackers.

Ewa, a chief security officer (CSO), has just discovered that unreleased designs of their next-generation vehicle are in the Car 'n' Driver magazine. What can she do to mitigate future design leaks to the public? A. Implement DLP. B. Implement MAC. C. Implement a forward proxy server. D. Install and program a firewall.
Answer: A Data loss prevention (DLP) is the best solution for stopping insider attacks like this. Mandatory access control (MAC) can help, but the insider leaking the designs may have top-secret clearance. A proxy server enforces security policies, such as which websites can be viewed. A firewall blocks unwanted traffic from entering the corporate network.
Which of the following is NOT a risk of creating an application with open source components? A. When developing under the LGPL license, the application must also be open sourced. B. The developer may stop supporting the component. C. The license may require fees if the primary application uses a for-profit model. D. The open source code may contain some proprietary content.
Answer: A Free software, although usually free of charge, allows users specific freedoms in terms of liberties; for example, the right to view the source code. The Lesser General Public License (LGPL) allows the developer to keep their source code closed, if desired, whereas the General Public License (GPL) requires that applications using GPL code must also open source their applications. The other risks can harm the developer financially. You can learn more here: https://www.gnu.org/licenses/lgpl-3.0.html.
Internal audit teams have what advantage over third-party auditing? A. Internal auditors have the best understanding of the technology, people, and processes. B. Internal auditors have exposure to other security methods that are used by other organizations. C. Internal auditors are not concerned with the impact of submitting a negative audit. D. Internal audits are looked at more favorably by regulators over third-party audits.
Answer: A In general, options B, C, and D are advantages of third-party audits.
Gregg is a security manager crafting a preparedness audit for the company. To run the audit, he gets help from his staff and members of the human resources and legal departments. Which type of audit is this? A. Internal B. External C. Third party D. Combination
Answer: A Internal audits are conducted by the organization's staff. External audits occur via a business supplier to ensure their security meets the policy. Since all the testers work for the organization, this is not a third-party audit because this requires hiring an outside organization to conduct the audit. A combination audit would be run by company resources and third-party resources. You can learn more here: https://quality-one.com/auditing/.
Yuki uses measurements based on all possible security alerts and monitors them weekly against her baseline and metrics to ensure she can reasonably protect the organization. These measurement indicators are known as what? A. KCI B. KGI C. KRI D. KPI
Answer: A KCIs are used to evaluate security controls and whether they stay within a given threshold. KRIs measure whether risks fall within tolerances. KPIs are a leading indicator to evaluate whether the organization is on target to achieve the desired goals or objectives. KGIs are lagging indicators that are evaluated once a goal has been reached, and they measure how well the goal was achieved.

Restoring systems back to standard operations after a disaster is known as disaster recovery. What is the process called where vital functions operate immediately after a disaster? A. Business continuity B. MTBF C. MTTR D. Disaster recovery
Answer: A Mean time between failure (MTBF) is a prediction as to when hardware will fail. Mean time to repair (MTTR) is the average time it takes to repair an item after a failure. MTBF and MTTR are related to events or incidents, not business-wide disasters.
Sari just opened her new SocCo soccer warehouse business and is ready to take orders on her brand-new multi-function fax machine. A few months later, she receives several complaints that someone representing SocCo is demanding payments for fees already paid, and desires repayment by gift cards. What is the MOST LIKELY problem here? A. Attackers collected customer information by hacking her fax machine. B. Her bill collection company mistakenly called clients because they never reconciled payments with SocCo. C. The clients never paid their bills, and the bill collection is in order. D. One of her staff mistakenly called the clients, thinking their accounts were past due.
Answer: A Multi-function printers attached to company networks are vulnerable to attacks and can grant a hacker access to the entire network, where they can exploit customer records. Bill collection companies and staff would not request payment via gift cards.
Before auditing work begins, each organization must understand the Terms of Engagement (ToE). Which of the following is NOT part of the ToE? A. Pricing B. Scope C. Responsibilities D. Requirements
Answer: A Pricing is part of the offer letter, after the terms of engagement (often called the rules of engagement) are completed. Scope, objective, definitions, responsibilities, how to handle changes, and requirements are all part of the written terms of engagement.
Paul is a security administrator reviewing audit logs from a security information and event management (SIEM) device. This activity would fall under which category? A. Detective B. Corrective C. Preventative D. Recovery
Answer: A SIEM devices are Intrusion Detection Devices (IDS), not intrusion prevention devices (IPS) such as firewalls. A corrective device corrects the asset state after an exploit; for example, a water sprinkler is a corrective device in case of a fire. Backup tapes are examples of recovery devices that return the asset to its normal state.
Oguchi is a hacker who has crafted an email to collect bank account numbers from victims when they click the link inside it. He sends this email to the COOs and CFOs of Standard Federal. What type of attack is this? A. Whaling B. Spear phishing C. Vishing D. Phishing
Answer: A Spear phishing is close, but since he is targeting Chief Operating Officers (COOs) and Chief Financial Officers (CFOs), this is whaling because they are high-level executives that have more knowledge about the organization. Phishing is similar, but phishing attacks are sent to a broad community, and vishing is done by phone, not email.
What is the next step of the audit process after conducting the audit? A. Document the results. B. Inform management. C. Determine the goals. D. Select audit team members.
Answer: A The eight-step process is 1) Determine goals, 2) Choose business unit(s), 3) Determine scope, 4) Select the audit team, 5) Audit planning, 6) Conduct the audit, 7) Document results, and 8) Communicate the results.
Jozy is a security analyst reviewing log files as part of a standard audit. He has noticed that apparent threats have attempted access at 2 A.M. on system A, but at 4 P.M. on system B. He checks the date on both systems and sees that it's incorrect on one of them. Which utility needs to be set up or tuned properly? A. NTP B. BIND C. DNS D. NAMED
Answer: A The network time protocol (NTP) ensures that all the systems are time-synchronized from a standard server. Domain name service (DNS), NAMED, and BIND are all domain name search utilities.
What is the process called where one set of systems runs in a test environment, but gets switched to a production environment when testing completes? The systems that were running in production are now in the test environment. A. Blue-green deployment B. Purple deployment C. Test-prod deployment D. Red-blue deployment
Answer: A The production systems may be on the green servers and being tested on the blue servers. Once testing is complete, blue gets switched to production, and green becomes the test environment. The other options are false options. Red-blue teams are used in ethical hacking exercises, where red is the threat and blue is the defender. Purple members maximize the effectiveness of the hacking exercise. You can learn more here: https://blog.christianposta.com/deploy/blue-green-deployments-a-b-testing-and-canary-releases/.
Which function assists administrators in determining how many shoppers did NOT complete a sale on the website? A. User activity telemetry B. Transaction telemetry C. Application telemetry D. Dependency telemetry
Answer: A User activity telemetry informs administrators of click streams that have been started and abandoned. Transaction telemetry is a false option; there is a feature called transaction traceability that monitors workloads. Application telemetry monitors error messages and the response times of web apps. Dependency telemetry monitors varied response times, such as networks or databases.
What are two aspects of compliance audits? (Choose two) A. They prove that the auditee is following regulatory requirements. B. They must be exclusively performed by third-party auditors. C. They must be exclusively performed by internal auditors. D. They prove that the auditee is following their policies.
Answer: A and B Compliance audits are performed because an organization such as a power plant or brokerage firm needs to show they are following the regulations for their industry.
Two programs that contain lists of known cybersecurity vulnerabilities, displaying an identification number of each vulnerability and description, would be which of the following? (Choose two) A. CVD B. NVD C. MITRE D. NIST
Answer: A and B MITRE is a community-driven effort that tracks and provides the common vulnerabilities and exposures (CVE) list. The national vulnerability database (NVD), provided by NIST, syncs the CVE list of vulnerabilities to their list.
Which two of the following Service Organization Controls (SOC) reports are Type I and Type II reports? (Choose two) A. SOC 1 B. SOC 2 C. SOC 3 D. SOC 4
Answer: A and B The SOC 3 report, which is provided by suppliers, contains general information that's usually posted on a website to prove that an organization practices good security protocols. SOC 4 reports do not exist.
The practice of conducting timely network vulnerability scans helps to discover which two exposures? (Choose two) A. Open ports B. Poor passwords C. Unauthorized services D. File modifications
Answer: A and C Poor password testing is done with tools such as Cain & Abel or John the Ripper. File modifications are checked with integrity checkers such as Nessus. Open ports are checked with tools such as Nmap.
Carli is a security auditor providing results of her audit to the firm. A good audit report contains what types of data? (Choose two) A. Likely threats and vulnerabilities B. A list of known attackers and locations C. An estimate of repair fees that an auditor can provide D. Probability and impact of the exploitation
Answer: A and D A good technical audit also lists the recommended actions to take to reduce the impact of exploitation. A list of attackers and locations is too numerous, and changes by the minute. The auditor must not be the repair person because this is poor separation of duties, and therefore insecure.
Hedvig is a developer who just completed unit testing for her product. Once this test has passed, which test should she run to ensure the entire product is valid before releasing it to production? (Choose two) A. End-to-end testing B. Performance testing C. More unit testing D. Integration testing
Answer: A and D End-to-end testing checks the entire system, while integration testing validates that the different units work together. More unit testing is not necessary, and performance testing tests the product under varied loads, but not in terms of functionality.
Timely log reviews are conducted because they help security professionals uncover which kinds of issues? (Choose two) A. Detect attackers attempting to break into the network. B. Zero days. C. Whether users are using strong passwords. D. Whether files are being modified via integrity checks.
Answer: A and D Zero days are undiscovered vulnerabilities, so log reviews cannot detect these. Authentication tools force users to use strong passwords.
Dzsenifer is an ethical hacker who has been hired by RCG Credit Union to find security vulnerabilities as if she were a high-level executive at the bank. What type of testing is this? A. Gray box testing B. White box testing C. Black box testing D. Red box testing
Answer: B A high-level executive has complete knowledge of the environment and demonstrates the biggest risk as an internal threat to an organization. A black box test simulates an external attacker having no knowledge of the environment. A gray box test simulates some knowledge of the organization, such as an administrator or engineer. Red box is a false option.
Users have been split into two groups to test whether a single difference in a social media website keeps users more interested in the website and on it for longer. What is this testing called? A. Negative testing B. A/B testing C. Red/blue teams D. Penetration testing
Answer: B A/B testing is a basic controlled experiment where a single difference is tested. Red and blue teams are used as part of penetration testing. The red team acts as the hacker, while the blue team acts as the defender. Negative testing hardens applications, checking to see how they will respond to unwanted input.
Arnie is a software developer and suggests to his supervisor to delay the project 1 week so that he can update the application with security mitigations. Why should his supervisor take this advice? A. Because delays are normal in software development projects. B. It costs significantly less to resolve security issues earlier in the process than later. C. Customers are trained to expect projects to always be delayed. D. You should always strive for perfect security.
Answer: B According to NIST and the Poleman Institute, repairs that might cost $80 to fix during development end up costing $240 to fix at build time. If you were to repair during the quality assurance (QA) process, it would cost $960, and after production, it would cost $7,600. You can learn more about defect costs here: https://owasp.org/www-pdf-archive/APAC13_Keynote_HyojinChoi.pdf.
Nikita is a systems administrator who is in charge of recovering data on a server because the hard drive has crashed. She starts the recovery process and learns that the backup tapes are blank. What did the team neglect to do? A. Test the RAID 0 (zero) system. B. Perform backup verification. C. Use the correct backup tape size. D. Enable encrypted and compressed backups.
Answer: B After encrypted and compressed backups are made, they must be tested. RAID 0 systems don't data mirroring like RAID 1 systems do. If the backup tapes did not physically fit, they would have discovered that much earlier.
What is one of the BEST ways of ensuring the business continuity plan stays up to date? A. Updating BCPs is not required if desk checks are done properly. B. Keep the BCP updated as part of change management. C. Conduct quarterly reviews of the BCP. D. Conduct annual reviews of the BCP.
Answer: B As new systems and software are added to the environment, always ask what effect this change will have on business continuity. This is normally done within the change management process. Most teams run change management weekly, so updates are frequent.
Kosovare runs a security training class for her team, teaching them to ask people "Did you forget your badge?" if they see someone wandering around the building without their badge. What can she do to be certain that staff are following their training? A. Run example scenarios in class, pretending someone does not have a badge. B. Hire an ethical hacker to wander around the building without a badge. C. Leave a badge lying in the parking lot and see if someone tries to use it. D. Ask security not to check for badges and allow anyone into the building.
Answer: B Asking security not to check for badges leaves the entire building insecure; this should never be done. Leaving a badge in the parking lot to see if it will be abused is testing a different scenario; we are concerned with people not wearing a badge. Example scenarios in the class are good, but an ethical hacker runs a live case scenario and can provide a report on the experience.
Buffer overflow attacks occur because of poorly written applications. Attackers can exploit this vulnerability and can potentially gain access to the entire computer. They are called buffer overflow attacks because these attacks occur where? A. Spaces on hard drives where files have been marked for removal B. The main memory of the computer C. Unused space in applications D. Unused space within files
Answer: B Data that's written within unused space is called a SNOW attack, a type of steganography attack that hides attacks in plain sight.
An open sourced utility that runs vulnerability scans and penetration tests on a website is called what? A. OWASP APPSEC B. OWASP ZAP C. OWASP API D. OWASP WEBGOAT
Answer: B Features include an intercepting proxy server, automation tools, fuzz testing, and script support. OWASP Webgoat is an intentionally vulnerable website you can practice on with OWASP ZAP. OWASP AppSec Pipeline applies DevOps and Lean principles for designing secure applications. OWASP API Security Project focuses on mitigating vulnerabilities in application programming interfaces (APIs).
Which of the following is NOT a requirement of the payment card industry data security standard (PCI DSS)? A. Protect stored cardholder data. B. Collect the logins and passwords of each online customer. C. Restrict physical access to cardholder data. D. Regularly test security systems and processes.
Answer: B Maintaining account information for online customers is not a requirement of PCI-DSS.
Virgil is a certified ethical hacker hired to find vulnerabilities in the GRC Bank website as if he were a malicious attacker. What type of testing is he conducting? A. Purple box testing B. Black box testing C. Gray box testing D. White box testing
Answer: B Malicious hackers have no internal knowledge of the environment. White box testing simulates an internal attacker because they have full knowledge of the environment. Gray box means the hacker has some knowledge of the internal environment. Purple box is a false option.
Cloud vendors maintain data and applications using which life cycle steps? A. Migrate --> secure --> monitor --> protect --> configure --> govern B. Migrate --> secure --> protect --> monitor --> configure --> govern C. Migrate --> secure --> protect --> monitor --> govern --> configure D. Migrate --> protect --> secure --> monitor --> configure --> govern
Answer: B Migration refers to moving data to the cloud vendor. Securing data is ensuring that the software can defend known threats. Protection ensures the data is always available; part of this is making backups. Monitoring tracks the health and availability of data. Configuring ensures that the application is set up to run efficiently. Governance ensures that applications correspond to the policy that has been set up.
Good vulnerability reduction practices include all the following, Except for what? A. Patch updates B. New software C. Closing unused ports D. Firmware updates
Answer: B New software generally contains bugs and needs to be updated and patched immediately. The others are good vulnerability reduction practices.
Debinha is an application developer who has completed a program that accepts credit cards. She simulates being a hacker, attempting to steal credit card information. This is an example of what kind of testing? A. Normal case testing B. Misuse case testing C. Static code analysis D. Code review
Answer: B Normal case testing assumes that you are attempting to use the software in a normal manner, not as an attacker. Code review and static analysis involves other members of the team reviewing each other's source code for the application.
A feature that's available in cloud systems monitors specific metrics to determine if more memory, CPU, or disk space is needed for an application to run efficiently. Once the loads return to normal, the system requirements return to normal. What is this feature called? A. On-demand self-service B. Autoscaling C. Measured service D. Resource pooling
Answer: B On-demand self-service does not operate automatically but requires manual intervention when it comes to adding resources. Measured services can provide more services manually, but not automatically. Resource pooling allows multiple tenants to share resources; if one user overloads the system, it will affect all the users.
When an architect, designer, or developer reuses parts, components, or code instead of validating new replacements, the individual is engaged in which activity? A. Band-aiding B. Technical debt C. Refactoring D. Poor testing
Answer: B Poor testing, band-aiding, and code refactoring, such as reusing code and making small changes so that it works in the new software, are all components of technical debt. These quick fixes are left unvalidated and can end up costing much more to fix as the project moves closer to production.
Diego is an IT manager getting reports that three smaller departments have suffered from ransomware attacks. Because of the company having proper backups, no payments were made. What is his next BEST step? A. Pay the attackers. B. Run phishing exercises. C. Respond with ransomware attacks against the hackers. D. Have staff sign an agreement on not clicking on ransomware links.
Answer: B Ransomware against hackers is considered a hack-back and is against the law. An employee agreement will not help. Most users are fooled into clicking ransomware links since they appear to be normal.
Bug number 535 was fixed with patch number 1. Bug number 435 was fixed with patch number 2. After customers installed patch number 2, several calls to support stated bug number 535 was returned. What type of testing was NOT done in this scenario? A. Acceptance testing B. Regression testing C. Performance testing D. Unit testing
Answer: B Regression testing ensures no functionality is lost or that past fixed problems are not reintroduced into the system. Acceptance testing focuses on meeting requirements. Performance testing checks how the system responds to different loads. Unit testing checks an individual module; this usually results in regression problems because examiners do not continue with a full functional or integration test.
Which of the following SOC reports not only affirms that security controls are in place, but also lists the effectiveness of the security controls? A. SOC 2 - Type I B. SOC 2 - Type II C. SOC 3 - Type I D. SOC 3 - Type II
Answer: B SOC 3 reports do not have differing types, and SOC 2 - Type I shows that security controls are in place.
Davici is an auditor. As part of their inspection, they must review a room where no cameras are allowed due to the risk of a fire occurring. What is his next BEST step? A. Conduct the audit within the room and shoot fewer pictures because the risk of a fire occurring is low. B. Conduct the audit within the room and sketch drawings where required. C. Skip the room; if the rest of the audit passes, provide a positive complete certification. D. Cancel the audit and delay the final certification.
Answer: B Safety first, even when conducting an audit.
A hacker dials multiple phone numbers, attempting to find modems and fax machines. What is this attack called? A. Sandstorm B. War dialing C. War driving D. WarVOX

One key advantage of virtual machines related to security is which of the following? A. The ability to run applications B. The ability to take snapshots C. The ability to run the Windows operating system D. The ability to run the Linux operating system
Answer: B Snapshots are instant backups. Virtual machines can make snapshots daily, or even more frequently. When data needs to be recovered, it is as simple as reverting to a snapshot, which is much faster than recovering from a backup tape.
Frankie is taking 3 months of leave from AMCO Inc. to stay with his family because they just had a child. How should his accounts be managed while he is gone? A. Make no changes to his account access. B. Suspend his login credentials. C. Make no changes to his account access but enforce a password change upon his return. D. Delete his account.
Answer: B Temporarily suspending access protects Frankie's data. At the same time, the account is not vulnerable to hackers since it has been temporarily closed. Timely password changes are important, but if the account is left open while he is gone, it is still vulnerable to attack.
Which of the following is NOT a requirement of the payment card industry data security standard (PCI DSS)? A. Maintain a firewall to protect cardholder data. B. Securely store credit card numbers and CVC codes. C. Do not use default settings or default passwords. D. Use and regularly update antivirus software.
Answer: B The card verification code (CVC) that is on the back of most credit cards should not be saved by the merchant.
QWRK Inc.'s software product has just released an update for their application. Soon, the hotline is overwhelmed with calls about a defect. What is the MOST LIKELY thing to have occurred? A. Users have not upgraded to the latest release of the application. B. A developer did not test the code before pushing it to the Git master branch. C. QWRK's hotline is the victim of a Telephony Denial of Service (TDoS) attack. D. Several hundred customers had their caps lock key on when they tried to enter their new passwords.
Answer: B The hotline was not overwhelmed until the new software was released, so customers performed the update. The attacker behind a TDoS attack would not hang on the phone line long enough to open a service call about a defect. Most systems warn users that their Caps Lock key is on when entering their passwords.
Griedge is a network administrator who keeps router and switch firmware updated. She scans each update for malware and verifies the hash values. Users have noticed anomalies in the network and have discovered that hackers have gained entry. What caused this? A. A hacker was able to infect the routers and switches with malware after the firmware updates. B. A hacker was able to get malware installed in the firmware source code. C. An inside attacker infected the routers and switches with malware after the firmware updates. D. Untrained users unintentionally installed malware on their routers and switches after the firmware updates.
Answer: B The update developer created a hash value in the code they believed was credible; therefore, the resulting hash gets marked as trusted, even though the code should be marked as untrusted. Malware protection scanners would have picked up issues in options A, C, and D.
A computer job is running multiple threads. The value from thread A is passed to thread B a few seconds after the value is defined. If the value is altered within the few seconds before it reaches thread B, and thread B uses this new value, what kind of error occurs? A. Bug B. TOCTOU C. Docker D. Race condition
Answer: B This is a bug, but there is a more specific answer. Time-of-check to time-of-use (TOCTOU) is the result of a race condition where the value is not verified immediately before it's used by the next computational thread. Docker is a utility that's used to clone a virtual machine image.
Antoine is an auditor who needs to conduct an audit remotely from home because of a worldwide pandemic. An issue is discovered during the planning phase. What must be resolved? A. There is no such thing as a remote audit. All audits must be conducted onsite. B. Antoine currently uses dial-up internet at his home. C. Wireless internet at the company site is secure. D. The equipment operator does not like appearing on camera.
Answer: B This question is intentionally vague because the real exam contains some questions like this where certain likely assumptions must be made; that is, to conduct a remote audit, there will need to be a live video feed. Dial-up internet is too slow for viewing the video stream from the audit site. Remote audits are allowed, if necessary, for example, during a worldwide pandemic. Corporate policies should cover whether an employee can be on camera. You can learn more about audits at https://iaf.nu/articles/FAQ/288.
Hugo runs the business continuity planning board. After completing other testing, he is ready to run a full test in the production environment. Which test should he choose to run? A. Structured walkthrough test B. Full interruption test C. Desk check test D. Checklist test
Answer: B Walkthroughs are what they sound like, where the team walks through a scenario without touching the production systems. Desk checks and checklist tests allow the team to discuss scenarios and make educated guesses as to how to best recover from disaster. Full interruption tests use live systems to evaluate responses to a disaster.
Earnie is developing a website and has concerns that the website will look different on a smartphone, a computer, and a tablet. What kind of testing can he do to ensure the website will look good on all devices? A. Website testing B. Interface testing C. Code review D. Misuse case testing
Answer: B Website testing is too general an answer. Interface testing is specifically what needs to be done: testing the website with each device. A code review is where the source code is inspected by a team, while misuse testing is intentionally trying to break the software's security.

Two free, open source utilities that security administrators use to verify whether users are prone to phishing attacks are called what? (Choose two) A. Hak5 B. Gophish C. Kali D. King Phisher
Answer: B and D Hak5 and Kali provide security toolkits that contain phishing simulators, but these are general-purpose ethical hacking utilities. Gophish and King Phisher provide phishing simulators with GUI environments showing users that fell victim to the email.
Pernille just ran a scan on her website and discovered that a hacker dropped files into her web server. The result of this test is considered which of the following? A. False positive B. False negative C. True positive D. True negative
Answer: C A true negative rarely gives an alert because no problem has been detected. An example of a false positive is when a user attempts to download a file but is denied because the system incorrectly sees them as a threat. A false negative would not have reported a website breach. To learn more about true and false positives and how they work, visit https://bit.ly/3cTBFIU.
Vivianne is a security tester working with management to determine which systems and departments to examine for an assessment. They also need to explain which processes need to be monitored. This is an example of which phase of the penetration test? A. Executing exploits B. Conducting documentation C. Defining the scope D. Running reconnaissance
Answer: C After defining the scope of an audit, penetration testing includes reconnaissance, enumeration, vulnerability analysis, launching the exploit, and documenting the final report for management.
The main difference between a business continuity plan (BCP) and a disaster recovery plan (DRP) is which of the following? A. The BCP requires testing, but the DRP does not because it is not as critical as business continuity. B. The DRP ensures the core business functions operate during a disaster; the BCP details steps to restore to normal operations after a disaster. C. The BCP ensures the core business functions operate during a disaster; the DRP details steps to restore to normal operations after a disaster. D.

Which BEST represents the five-step penetration testing process? A. Reconnaissance --> Assess vulnerabilities --> Scan --> Exploit --> Reporting B. Reconnaissance --> Scan --> Exploit --> Assess vulnerabilities --> Reporting C. Reconnaissance --> Scan --> Assess vulnerabilities --> Exploit --> Reporting D. Reconnaissance --> Exploit --> Assess vulnerabilities --> Scan --> Reporting
Answer: C Reconnaissance allows the attacker to collect information about a target, such as their IP address and location. The scanning phase is where the attacker enumerates the devices that have been found. Next, they need to see which devices are vulnerable. Finally, an ethical hacker will launch exploits without causing harm and report the findings to management.
