Secure Software Implementation questions often show small code snippets or scenario choices asking which practice prevents a specific vulnerability, and I found buffer overflow and crypto misuse scenarios especially tricky, I passed the exam and thanks Pass4Success for providing good collection of exam questions for preparation in short time. Focus your study on secure coding standards, language-specific pitfalls, and how SAST tools flag real issues so you can recognize secure vs insecure fixes.

When I took the CSSLP the scenario-based threat modeling questions that asked me to pick the single best mitigation were the most confusing. Practicing a few threat models under time pressure and sketching attack paths helped me answer faster.

Free ISC2 CSSLP Exam Actual Questions

Note: Premium Questions for CSSLP were last updated On Jun. 05, 2026 (see below)

Question #1

Frank is the project manager of the NHH Project. He is working with the project team to create a plan to document the procedures to manage risks throughout the project. This document will define how risks will be identified and quantified. It will also define how contingency plans will be implemented by the project team. What document is Frank and the NHH Project team creating in this scenario?

Reveal Solution Hide Solution
Correct Answer: A

The risk management plan, part of the comprehensive management plan, defines how risks will be identified, analyzed, monitored and

controlled, and even responded to.

A Risk management plan is a document arranged by a project manager to estimate the effectiveness, predict risks, and build response plans

to mitigate them. It also consists of the risk assessment matrix.

Risks are built in with any project, and project managers evaluate risks repeatedly and build plans to address them. The risk management

plan consists of analysis of possible risks with both high and low impacts, and the mitigation strategies to facilitate the project and avoid

being derailed through which the common problems arise. Risk management plans should be timely reviewed by the project team in order to

avoid having the analysis become stale and not reflective of actual potential project risks. Most critically, risk management plans include a risk

strategy for project execution.

Answer C is incorrect. The project management plan is a comprehensive plan that communicates the intent of the project for all project

management knowledge areas.

Answer B is incorrect. The project plan is not an official PMBOK project management plan.

Answer D is incorrect. The resource management plan defines the management of project resources, such as project team members,

facilities, equipment, and contractors.


Question #2

Mark is the project manager of the NHQ project in StarTech Inc. The project has an asset valued at $195,000 and is subjected to an exposure factor of 35 percent. What will be the Single Loss Expectancy of the project?

Reveal Solution Hide Solution
Correct Answer: A

The Single Loss Expectancy (SLE) of this project will be $68,250.

Single Loss Expectancy is a term related to Risk Management and Risk Assessment. It can be defined as the monetary value expected from

the occurrence of a risk on an asset. It is mathematically expressed as follows:

Single Loss Expectancy (SLE) = Asset Value (AV) * Exposure Factor (EF)

where the Exposure Factor is represented in the impact of the risk over the asset, or percentage of asset lost. As an example, if the Asset

Value is reduced two thirds, the exposure factor value is .66. If the asset is completely lost, the Exposure Factor is 1.0. The result is a

monetary value in the same unit as the Single Loss Expectancy is expressed.

Here, it is as follows:

SLE = Asset Value * Exposure Factor

= 195,000 * 0.35

= $68,250

Answer B, C, and D are incorrect. These are not valid SLE's for this project.


Question #3

Which of the following is used by attackers to record everything a person types, including usernames, passwords, and account information?

Reveal Solution Hide Solution
Correct Answer: B

Keystroke logging is used by attackers to record everything a person types, including usernames, passwords, and account information.

Keystroke logging is a method of logging and recording user keystrokes. It can be performed with software or hardware devices. Keystroke

logging devices can record everything a person types using his keyboard, such as to measure employee's productivity on certain clerical tasks.

These types of devices can also be used to get usernames, passwords, etc.

Answer D is incorrect. Wiretapping is used to eavesdrop on voice calls. Eavesdropping is the process of listening in on private

conversations. It also includes attackers listening in on network traffic.

Answer C is incorrect. Spoofing is a technique that makes a transmission appear to have come from an authentic source by forging the

IP address, email address, caller ID, etc. In IP spoofing, a hacker modifies packet headers by using someone else's IP address to hide his

identity. However, spoofing cannot be used while surfing the Internet, chatting on-line, etc. because forging the source IP address causes the

responses to be misdirected.

Answer A is incorrect. Packet sniffing is a process of monitoring data packets that travel across a network. The software used for

packet sniffing is known as sniffers. There are many packet-sniffing programs that are available on the Internet. Some of these are

unauthorized, which can be harmful for a network's security.


Question #4

The service-oriented modeling framework (SOMF) introduces five major life cycle modeling activities that drive a service evolution during design-time and run-time. Which of the following activities integrates SOA software assets and establishes SOA logical environment dependencies?

Reveal Solution Hide Solution
Correct Answer: C

The service-oriented logical architecture modeling integrates SOA software assets and establishes SOA logical environment dependencies. It

also offers foster service reuse, loose coupling and consolidation.

Answer A is incorrect. The service-oriented discovery and analysis modeling discovers and analyzes services for granularity, reusability,

interoperability, loose-coupling, and identifies consolidation opportunities.

Answer B is incorrect. The service-oriented business integration modeling identifies service integration and alignment opportunities

with business domains' processes.

Answer D is incorrect. The service-oriented logical design modeling establishes service relationships and message exchange paths.


Question #5

The Web resource collection is a security constraint element summarized in the Java Servlet Specification v2.4. Which of the following elements does it include?

Each correct answer represents a complete solution. Choose two.

Reveal Solution Hide Solution
Correct Answer: A, D

Web resource collection is a set of URL patterns and HTTP operations that define all resources required to be protected. It is a security

constraint element summarized in the Java Servlet Specification v2.4. The Web resource collection includes the following elements:

URL patterns

HTTP methods

Answer B is incorrect. An authorization constraint includes role names.

Answer C is incorrect. A user data constraint includes transport guarantees.
