"Data at rest"

"Data at rest" is a state describing data in storage. This is used to describe encrypted data on a hard disk drive.

"Data in use"

"Data in use" is a state describing data present in volatile memory, such as system RAM or CPU registers and cache. Data is usually decrypted as it moves from disk to memory.

A company determined that their data center is worth about $500,000 in assets and data from its customers. Every so often, they are hit with a security incident where the single loss expectancy (SLE) totals about $25,000. If management determines that these instances may occur once a month next year, what will be the calculated annual rate of occurrence when calculating the annual loss expectancy (ALE)?

A data loss prevention (DLP) endpoint agent enforces policies on the client computers, even when they are not connected on the network. A DLP network agent scans communications at the network borders and interface with web servers to monitor file access and use. A DLP network agent scans communications at the network borders and interface with messaging servers to monitor file sharing in messages.

non-disclosure agreement (NDA)

A non-disclosure agreement (NDA) is non-technical security control representing the legal basis for protecting information assets. NDAs are used between companies and employees, between companies and contractors, and between two companies.

Continuous security monitoring (CSM) is a process of continual risk reassessment. Rather than an ad hoc process driven by incident response, CSM is an ongoing effort to obtain information vital in managing risk within the organization.

Watermarking

DLP solutions do not encode watermarks into files. Watermarking is a digital and most times visible marking encoded into the file or video to defeat attempts of removal from official channels, or so the file can be located if released on a file sharing site.

Purpose limitation

Purpose limitation is a non-technical control used in privacy regulations. It restricts an organization's ability to transfer data to third parties. Consent statements must be tracked to keep data usage in compliance.

Recovery point objective (RPO)

Recovery point objective (RPO) is the amount of data loss that a system can sustain, measured in time.

Recovery time objective (RTO)

Recovery time objective (RTO) is the period following a disaster that an individual IT system may remain offline. This is the amount of time it takes to identify that there is a problem and then perform recovery.

Return on security investment

Return on security investment (ROSI)

Return on security investment (ROSI) includes multiple factors such as the cost of the solution, and the reduction of the annual loss expectancy (ALE). ALE can depend a little on operational costs due to an incident happening or not, or even how quickly it is resolved.

Secret

Secret documentation is too valuable to allow any risk of its capture. This is strictly for persons within the military.

The National Institute of Standards and Technology (NIST) Cybersecurity Framework is risk-based and includes the framework core, implementation tiers, and framework profiles. The framework core identifies five cybersecurity functions (Identify, Protect, Detect, Respond, and Recover).

Sarbanes-Oxley Act (SOX)

The Sarbanes-Oxley Act (SOX) dictates requirements for the storage and retention of documents relating to an organization's financial and business operations. This includes storage of specific documents types, and their retention periods.

Windows security logs

The Windows security logs will provide the date and times a local account, or domain, was successful or unsuccessful in accessing the logs. Any attempts of using the account per the logs should be reported.

The audit process

The audit process is more rigid than evaluation and assessment strategies. An auditor uses a pre-defined baseline that they compare the organization's current state to, which helps the auditor find any specific violations that require remediation.

A company has been using a prescriptive framework to implement security controls. They have matured to a tier 3 organization and have learned many lessons along the way. Review the following descriptions and select the most applicable statement to this company's situation.

The company has defined policies and procedures.

Data Custodian

The data custodian handles managing the system that stores data assets. This includes responsibility for enforcing access control, encryption, and backup/recovery measures.

Data Owner

The data owner is a senior (executive) role with ultimate responsibility for maintaining the confidentiality, integrity, and availability of the information asset.

Data steward

The data steward is responsible for data quality. This involves tasks like labeling and identifying data with appropriate metadata. The data is collected and stored in a format, and with values, that comply with applicable laws and regulations.

The evaluation process

The evaluation process is aimed at examining outcomes or literally "proving usefulness." It will answer questions like, "Were there security breaches?" and "What was the response to an incident?"

The formula for annual loss expectancy (ALE)

The formula for annual loss expectancy (ALE) = SLE (Single Loss Expectancy) x ARO (Annual Rate of Occurrence).

frame (Risk Management)

The frame component establishes a strategic risk management framework, supported by decision-makers at the top tier of the organization. The risk frame sets an overall goal for the degree of risk tolerated and demarcates responsibilities.

The framework core

The framework core identifies five cybersecurity functions (Identify, Protect, Detect, Respond, and Recover). Each function can be divided into categories and subcategories.

Privacy Officer

The privacy officer is responsible for oversight of Personally Identifiable Information (PII), including company managed Person Health Information (PHI) assets. This ensures compliance in matters like data sovereignty and data retention.

Risk Frame

The risk frame sets an overall goal for the degree of risk that can be tolerated and demarcates responsibilities. The risk frame directs and receives inputs from all other processes.

The validation process

The validation process, during software development for example, determines whether the security system is fit-for-purpose (its design goals meet the requirements for a secure system).

The verification process

The verification process, during software development for example, is a compliance-testing process to ensure that the security system meets the requirements of a framework or regulatory environment.

Tier 1 in the prescriptive framework

Tier 1 in the prescriptive framework represents an organization that has a reactive approach to security. This means something bad happens and they scramble to fix it.

Tier 2 in the prescriptive framework

Tier 2 in the prescriptive framework represents an organization that prepares to mitigate cybersecurity risks by performing risk assessments.

Tier 3 in the prescriptive framework

Tier 3 in the prescriptive framework represents an organization with defined policies and procedures driven by the IT department.

Tier 4 in the prescriptive framework

Tier 4 in the prescriptive framework represents an organization that demonstrates management oversight of risks. They have risk-driven business policies and processes, and procedures for optimizing and continuously monitoring controls.

Unclassified or public documents have no restrictions. No NDA is required for this type of information.

Verification

Verification is a compliance-testing process to ensure that the security system meets the requirements of a framework or regulatory environment, or more generally, that a product or system meets its design goals.

Version Control

Version control helps when files and records change frequently, such as software code. This would apply to short term data retention policies created by an organization.

Which of the following might a company include in an acceptable user policy (AUP) for general users?
