This is a pattern matching technique that uses a structured database of string values to detect matches. For example, a company might have a list of actual social security numbers of its customers.

- Exact data match

This is a further refinement of partial document matching that uses machine learning to analyze various data sources using artificial intelligence or machine learning.

- Statistical matching

These techniques use a rule based on a confidentiality classification tag or label attached to the data. For example, the military might use a classification based DLP to search for any files labeled as secret or top secret.

- Classification

This attempts to match a whole document or a partial document against a signature in the DLP.

- Document matching

This refers to the attack method that takes many usernames and loops them with a single password.

- Password spraying

This is exploiting a valid computer session to gain unauthorized access to information or services in a computer system.

- Session hijacking

This is the automated injection of breached username/password pairs to gain user accounts access fraudulently. This is a subset of the brute force attack category: large numbers of spilled credentials are automatically entered into websites until they are potentially matched to an existing account. The attacker can then hijack for their own purposes.

- Credential stuffing

This is the act of pretending to be another person for fraud.

- Impersonation

What are the Seven phases of the Software Development Life Cycle (SDLC):

- Planning (or Requirements Planning), - Requirements and Analysis, - Design, - Development (or Coding/Implementation), - Testing, - Deployment, - Maintenance (or Operations and Monitoring)

During the 2017 WannaCry ransomware attack, cybersecurity professionals across organizations globally rushed to contain the spread and impact of the ransomware. In this effort, they used a variety of software solutions designed to detect, analyze, and respond to security incidents.

- Tokenization

This can mean that all or part of a field's contents are redacted, by substituting all character strings with x, for example.

- Data masking

This combines several programs into one, including writing to a temporary file, netcat usage, and FTP usage. This integrates more than one form of attack to accomplish their goal.

- Chained exploit

This attack occurs when legitimate users cannot access information systems, devices, or other network resources due to the actions of a malicious cyber threat actor.

- Denial of Service exploit

- SQL injection exploit

This is an anomaly where a program that occurs while writing data to a buffer overruns the buffer's boundary and overwrites adjacent memory locations.

- Buffer overflow exploit

After a successful spear-phishing attack, an adversary has gained access to your organization's network. The adversary then performs a Pass-the-Hash attack to gain administrative privileges, moves horizontally in the network, and finally exfiltrates sensitive data. Which stage of the MITRE ATT&CK framework does this movement represent?

- Lateral Movement

This refers to the final stage where the adversary exports the data they're after.

- Exfiltration

This involves stealing credentials, like the Pass-the-Hash attack mentioned. However, it doesn't refer to moving through the network.
