Data Loss Prevention Concepts

The video tutorial covers file integrity monitoring, emphasizing its role in security by detecting unauthorized changes to critical files. It introduces tools like SFC for Windows and Tripwire for Linux. The tutorial also explains host-based intrusion prevention systems and their ability to monitor file integrity. Data Loss Prevention (DLP) systems are discussed, highlighting their use in preventing unauthorized data transfers across networks, USB devices, and cloud applications. The video concludes with a focus on email-based DLP solutions, illustrating their importance in blocking sensitive data leaks, as exemplified by a Boeing incident.

What is the primary purpose of file integrity monitoring?

• To ensure files are backed up regularly

• To detect unauthorized changes to files

• To improve file access speed

• To compress files for storage

Which tool is used in Windows for file integrity monitoring?

• Windows Defender

• System File Checker (SFC)

• Tripwire

• Norton Antivirus

How does a host-based intrusion prevention system differ from a network-based one?

• It monitors network traffic only

• It operates on the operating system itself

• It requires no software installation

• It is used only for cloud applications

What is a key feature of Data Loss Prevention (DLP) systems?

• They encrypt all network traffic

• They enhance system performance

• They provide free cloud storage

• They block sensitive data transfers

What is the term for DLP monitoring of data in active memory?

• Data in motion

• Data in use

• Data in transit

• Data at rest

What incident led to the US Department of Defense banning USB drives?

• A phishing attack on employees

• A data breach in cloud storage

• A worm virus spread through USB drives

• A malware attack via email

How do cloud-based DLP solutions function?

• They store data in encrypted form

• They monitor and block sensitive data transfers to the cloud

• They provide free antivirus protection

• They enhance cloud application performance

What is a common threat vector for sensitive information in organizations?

• Mobile applications

• Email systems

• Public Wi-Fi networks

• Social media platforms

What can email-based DLP solutions detect in outgoing emails?

• Unsubscribed users

• Large attachments

• Sensitive information

• Spam content

What was the consequence of a Boeing employee sending a spreadsheet via email?

• The spreadsheet was encrypted

• Sensitive employee data was exposed

• The spreadsheet was deleted

• The email was blocked by DLP
