Study Notes
Data Protection
- Data in processing is data that is actively in use by a computer system and is stored in memory while processing takes place.
- An attacker with control of the system may be able to read the contents of memory and steal sensitive information.
Encryption
- Uses mathematical algorithms to protect information from prying eyes, both while in transit over a network and while residing on systems.
- Encrypted data is unintelligible to anyone who does not have access to the appropriate decryption key.
Data Loss Prevention (DLP)
- Helps organizations enforce information handling policies and procedures to prevent data loss and theft.
- Searches systems for stores of sensitive information that might be unsecured and monitors network traffic for potential attempts to remove sensitive information.
- Can act quickly to block the transmission before damage is done and alerts administrators to the attempted breach.
- Works in two different environments: Host-based DLP and Network DLP.
- Host-based DLP uses software agents installed on systems to search for the presence of sensitive information.
Risk Assessment
- The DAD triad (Confidentiality, Integrity, and Availability) can be used to inform a risk assessment.
- The CIA and DAD models can be used in almost any situation to serve as a helpful starting point for a more detailed risk analysis.
Impact of Security Incident
- The impacts of a security incident may be wide-ranging, depending upon the nature of the incident and the type of organization affected.
- The potential impact of a security incident can be categorized into: financial, reputational, strategic, operational, and compliance risks.
Financial Risk
- The risk of monetary damage to the organization as a result of a data breach.
- Direct financial risks include the costs of rebuilding a datacenter or contracting experts for incident response.
- Indirect financial risks include the costs of losing a laptop containing sensitive information.
Reputational Risk
- Occurs when negative publicity surrounding a security breach causes the loss of goodwill among stakeholders.
Identity Theft
- When a security breach affects customers, employees, and other individual stakeholders.
Compensating Controls
- Find alternative means to achieve an objective when the organization cannot meet the original control requirement.
- Balance the fact that it isn't possible to implement every required security control with the desire to manage risk to the greatest feasible degree.
- Adopted to address a temporary exception to a security requirement, with remediation plans to bring the organization back into compliance.
