Pass the IIBA Cybersecurity Analysis IIBA-CCA Questions and answers with CertsForce

Security categorization (commonly based on confidentiality, integrity, and availability impact levels) is meant to reflect the level of harm that would occur if an information type or system is compromised. A business impact analysis, on the other hand, examines the operational and organizational consequences of disruptions or failures—such as loss of revenue, inability to deliver critical services, legal or regulatory exposure, reputational harm, and impacts to customers or individuals. Because these two activities look at impact from different but related perspectives, categorization information should be used during the BIA to confirm that the stated security categorization truly matches real business consequences.

Using categorization as an input helps analysts validate assumptions about criticality, sensitivity, and tolerance for downtime. If the BIA shows that outages or data compromise would produce greater harm than the existing categorization implies, that discrepancy signals under-classification and insufficient controls. Conversely, if the BIA demonstrates limited impact, it may indicate over-classification, potentially driving unnecessary cost and operational burden. Identifying these mismatches early supports better risk decisions, prioritization of recovery objectives, and selection of controls proportionate to actual impact.

The other options describe activities that may occur in architecture, governance, or project planning, but they are not the primary purpose of using categorization information in a BIA. The key value is reconciliation: aligning security impact levels with verified business impact.

Data at restrefers to information that isstoredrather than actively moving across networks or being actively processed. This includes data saved on laptops and mobile devices, servers, databases, file shares, removable media, backup tapes, storage arrays, and cloud storage services. Because it sits in storage, the main risks involveunauthorized access(improper permissions, stolen credentials, insider misuse),theft or loss of devices/media, andmisconfiguration(publicly exposed storage buckets, overly broad shared drives). Data at rest is also at risk when systems are decommissioned or storage is reused without secure wiping.

Cybersecurity documents emphasize protecting data at rest using layered controls.Encryption at restensures stored files or database records remain unreadable without the proper key, reducing impact if storage is stolen or accessed improperly. Strongaccess controlandleast privilegelimit who can read or modify stored data, whilesegmentationand secure configuration reduce exposure pathways. Properkey management(separating keys from encrypted data, rotating keys, restricting key access) is critical so encryption meaningfully reduces risk. Additional controls includedata classification and handling rules, secure backups (including immutable or protected backups), monitoring and audit logging for sensitive repositories, and secure disposal practices such as cryptographic erase or verified wiping.

Options A and B describedata in transit, not at rest. Option D is incorrect because stored data is not automatically less vulnerable; it is often highly attractive to attackers, so it requires deliberate protection.

Privileged account management refers to the governance and operational controls used to administer accounts that haveelevated permissionsbeyond standard user access. Privileged accounts can change system configurations, create or modify users, access sensitive datasets, disable security tools, and administer core infrastructure such as servers, databases, directories, network devices, and cloud consoles. Because misuse of privileged access can quickly lead to large-scale compromise, cybersecurity frameworks treat privileged access as a high-risk area requiring stronger safeguards than normal accounts.

The definition in option A is correct because it captures the core purpose of privileged account management:establishing and maintaining access rights and controlsspecifically for roles that must perform administrative or support functions. In practice, this includes ensuring privileges are granted only when justified, scoped to the minimum necessary, and reviewed regularly. It also includes controls such as separation of duties, approval workflows, time-bound elevation, credential vaulting, rotation of privileged passwords and keys, multifactor authentication, and detailed logging of privileged sessions for monitoring and audit.

Option B is too broad because privileged account management is a specialized subset of identity and access management focused on elevated access. Option C is incorrect because privilege is defined by permissions, not job title. Option D describes an authentication concept, not the full management lifecycle of privileged access.

Ongoing, remote maintenance is one of the most effective ways to improve the security posture of embedded systems over time because it enables timely remediation of newly discovered weaknesses. Embedded devices frequently run firmware that includes operating logic, network stacks, and third-party libraries. As vulnerabilities are discovered in these components, organizations must be able to deploy fixes quickly to reduce exposure. Remote maintenance supports this by enabling over-the-air firmware and software updates, configuration changes, certificate and key rotation, and the rollout of compensating controls such as updated security policies or hardened settings.

Option B is correct because remote maintenance directly addresses the challenge ofdeploying updated firmwareas issues are identified. Cybersecurity guidance for embedded and IoT environments emphasizes secure update mechanisms: authenticated update packages, integrity verification (such as digital signatures), secure distribution channels, rollback protection, staged deployment, and audit logging of update actions. These practices reduce the risk of attackers installing malicious firmware and help ensure devices remain supported throughout their operational life.

The other options are not primarily solved by remote maintenance. Limited CPU and memory are inherent design constraints that may require hardware redesign. Battery and component limitations are also physical constraints. Physical security attacks exploit device access and hardware weaknesses, which require tamper resistance, secure boot, and physical protections rather than remote maintenance alone.

Designing an audit log report requires clarity onwho is allowed to do what, which actions are considered security-relevant, and what evidence must be captured to demonstrate accountability.Access Control Requirementsare the essential business analysis deliverable because they define roles, permissions, segregation of duties, privileged functions, approval workflows, and the conditions under which access is granted or denied. From these requirements, the logging design can specify exactly which events must be recorded, such as authentication attempts, authorization decisions, privilege elevation, administrative changes, access to sensitive records, data exports, configuration changes, and failed access attempts. They also help determine how logs should attribute actions to unique identities, including service accounts and delegated administration, which is critical for auditability and non-repudiation.

Access control requirements also drive necessary log fields and report structure: user or role, timestamp, source, target object, action, outcome, and reason codes for denials or policy exceptions. Without these requirements, an audit log report can become either too sparse to support investigations and compliance, or too noisy to be operationally useful.

A risk log can influence priorities, but it does not define the authoritative set of access events and entitlements that must be auditable. A future state process can provide context, yet it is not as precise as access rules for determining what to log. An internal audit report may highlight gaps, but it is not the primary design input compared to formal access control requirements.

Creating a fake website to trick individuals into entering usernames and passwords is a classic example of phishing. Phishing is a social engineering technique where an attacker impersonates a trusted entity to deceive a victim into disclosing sensitive information (credentials, personal data, payment details) or taking an action that benefits the attacker (downloading malware, approving an MFA prompt, wiring funds). A counterfeit login page is commonly used in credential-harvesting campaigns: the victim believes they are authenticating to a legitimate service, but the credentials are captured by the attacker and later used for account takeover. This is not necessarily a breach yet because the question describes an attempt to acquire credentials; a breach would be confirmed unauthorized access or disclosure. While phishing is a kind of threat, “threat” is too broad compared to the specific described behavior. It is also not ransomware, which focuses on encrypting or locking data and demanding payment. Cybersecurity documentation emphasizes layered defenses against phishing: user awareness training, email and web filtering, domain and certificate validation, anti-spoofing controls, strong authentication (especially MFA resistant to prompt fatigue), password managers that reduce credential entry on lookalike domains, and monitoring for suspicious logins. Because the attack relies on deception through a fake website to steal credentials, the best match is phishing.

Information classification is the practice of assigning data a sensitivity level so the organization can apply protections that match thebusiness impactif the information is exposed, altered, or becomes unavailable. The core driver for classification is therisk of harm—especially harm caused by unauthorized disclosure. If disclosure would result in regulatory penalties, reputational damage, competitive disadvantage, contractual breach, or harm to customers and employees, the data is classified at a higher level and requires stronger controls. These controls commonly include tighter access restrictions (least privilege and role-based access), stronger authentication, encryption at rest and in transit, stricter handling and sharing rules, audit logging, monitoring, and secure disposal requirements.

While retention can be influenced by compliance obligations, it is not what determines the classification level; retention policies typically reference classification but do not define it. “Need for access” is managed through access control decisions, which are appliedafterthe data’s sensitivity is understood; classification informs who should have access, not the other way around. “Timing of availability” relates to availability requirements and service resilience, which are important, but classification schemes primarily focus on sensitivity and potential damage from inappropriate exposure, with integrity and availability considerations often handled as additional impact dimensions.

Therefore, the best verified basis for information classification is the organization’s assessment ofrisk of loss or harm from disclosure.

Apatchis a vendor- or developer-provided update intended to correct defects in software, includingprogramming errorsandsecurity vulnerabilities. Cybersecurity and IT operations documents describe patching as a primary method of vulnerability remediation because many attacks succeed by exploiting known weaknesses for which fixes already exist. When a vulnerability is disclosed, the vendor may publish a patch that changes code, updates components, adjusts configuration defaults, or replaces vulnerable libraries. Applying the patch reduces the likelihood that an attacker can use that weakness to gain unauthorized access, execute malicious code, elevate privileges, or disrupt availability.

A patch is different from acontrol, which is a broader safeguard (technical, administrative, or physical) used to reduce risk; patching itself can be part of a control, such as a patch management program. It is also different from arelease, which is a broader software distribution that may include new features, improvements, and multiple fixes; a patch is usually more targeted and may be issued between major releases. Alogis an audit record of events and is used for monitoring, troubleshooting, and incident investigation—not for fixing code defects.

Cybersecurity guidance emphasizes disciplined patch management: maintaining asset inventories, prioritizing patches by risk and exposure, testing changes, deploying promptly, verifying installation, and documenting exceptions to manage residual risk.

Cybersecurity regulations most commonly focus on the protection ofpersonal data, because misuse or exposure can directly harm individuals through identity theft, fraud, discrimination, or loss of privacy. Privacy and data-protection laws typically require organizations to implement appropriate safeguards to protect personal information across its lifecycle, including collection, storage, processing, sharing, and disposal. In cybersecurity governance documentation, this obligation is often expressed through requirements to maintain confidentiality and integrity of personal data, limit access based on business need, and ensure accountability through logging, monitoring, and audits.

Demonstrating protection of personal data generally includes having a documented data classification scheme, clearly defined lawful purposes for processing, retention limits, and secure handling procedures. Technical controls commonly expected include strong authentication, least privilege and role-based access control, encryption for data at rest and in transit, secure key management, endpoint and server hardening, vulnerability management, and continuous monitoring for suspicious activity. Operational capabilities such as incident response, breach detection, and timely notification processes are also emphasized because regulators expect organizations to manage and report material data exposures appropriately.

While protecting applications, intellectual property, and ensuring continuity are important security objectives, they are not the primary focus of many cybersecurity regulations in the same consistent way aspersonal data protection. Therefore, the best answer is personal data of customers and employees.

A risk score is commonly calculated by combining two core factors: how likely a risk scenario is to occur and how severe the consequences would be if it did occur. This is often described in cybersecurity risk documentation as likelihood times impact, or as a structured mapping using a risk matrix.Probability or likelihoodreflects the chance that a threat event will exploit a vulnerability under current conditions. It may consider elements such as threat activity, exposure, ease of exploitation, control strength, and historical incident patterns.Impactreflects the magnitude of harm to the organization, usually measured across business disruption, financial loss, legal or regulatory exposure, reputational damage, and harm to confidentiality, integrity, or availability.

While confidentiality, integrity, and availability are essential for understanding what matters and can influence impact ratings, they are typically inputs into impact determination rather than the full scoring method by themselves. Past experience and expert threat assessment can inform likelihood estimates, but they are not the standard calculation model on their own. The key concept is that risk must reflect both chance and consequence; a highly impactful event with very low likelihood may be scored similarly to a moderate impact event with high likelihood depending on the organization’s methodology.

Therefore, the most accurate description of how a risk score is calculated is the combination of probability and impact, enabling prioritization and consistent risk treatment decisions.
