Data breaches and data leaks differ in their intent and occurrence. A data breach involves intentional attacks by malicious actors, while a data leak occurs unintentionally due to technical failures or human errors.

Data Breach:

Definition: The unauthorized access and retrieval of sensitive information by an individual or group with malicious intent.

Characteristics: Deliberate and targeted attacks aiming to steal or compromise data.

Examples: Hacking, phishing, and malware attacks.

Data Leak:

Definition: The unintentional exposure of sensitive information due to negligence, technical failures, or human errors.

Characteristics: Accidental and usually not intended to harm the organization.

Examples: Misconfigured servers, accidental sharing of files, and lost or stolen devices.

ISO/IEC 27001: Emphasizes the importance of protecting information against both intentional and unintentional disclosures.

NIST SP 800-53: Recommends controls to prevent both data breaches and data leaks, highlighting the different nature of these threats.

Detailed Explanation:Cybersecurity References:Understanding the differences between data breaches and data leaks helps organizations implement appropriate measures to prevent both types of incidents.

Reporting IDS alerts of malicious transactions to interested parties does not ensure the ongoing security of an Intrusion Detection System (IDS). While it is important for situational awareness and incident response, it does not directly contribute to the security and maintenance of the IDS itself. Ensuring ongoing security of an IDS involves activities such as encrypting IDS management communications and creating unique user and administrator accounts for every IDS system, which help protect the IDS from being compromised. References include NIST SP 800-94, which provides guidelines for securing IDS systems.

In the scenario provided, the organization operating in the food industry has warehouses storing large amounts of valuable products that are unprotected and lack proper surveillance. This presents a clear vulnerability that can be exploited. The most likely threat associated with this vulnerability is theft.

Theft involves the unauthorized taking of physical goods, and in the context of unprotected warehouses, it becomes a significant risk. Proper surveillance and physical security measures are critical controls to prevent such incidents. Without these, the organization’s assets are at risk of being stolen, leading to significant financial losses and operational disruptions.

ISO/IEC 27002:2013- Provides guidelines for organizational information security standards and information security management practices, including the selection, implementation, and management of controls. It addresses physical and environmental security, which includes securing areas that house critical or valuable assets.

NIST SP 800-53- Recommends security controls for federal information systems and organizations. It includes controls for physical and environmental protection (PE), which cover measures to safeguard physical locations and prevent unauthorized physical access.

A computer security incident is best described as an event where an attacker exploits a vulnerability to command a botnet and launch a distributed denial-of-service (DDoS) attack on a web server. This type of incident involves unauthorized access and malicious activity aimed at disrupting the availability of a web service. Such incidents are typically included in the scope of security incidents because they involve breaches of security policy and pose significant risks to the affected systems. References include NIST SP 800-61, which defines and categorizes computer security incidents.
