56
Q

Hash digest or hash function

A

A hash digest, also known as a hash value or hash code, is the output generated by a hash function when it processes input data. A hash function is a mathematical algorithm that takes an input (such as a file, message, or data) and produces a fixed-size alphanumeric string, which represents a unique “digest” of the input. The hash function processes the input in a way that any slight change in the input will result in a significantly different hash value. Hash functions are commonly used in cryptography, data integrity verification, password storage, and digital signatures.

57
Q

Hashing

A

Hashing is the process of applying a hash function to input data in order to generate a fixed-size output, known as a hash value or hash code.

A

RPO represents the maximum tolerable amount of data loss that an organization can afford during a disruption or disaster. It defines the point in time to which data must be recovered in order to resume operations with an acceptable level of data integrity. RPO is often measured in terms of time, indicating the maximum acceptable time gap between the last data backup and the occurrence of the disruption.

70
Q

A

SQL (Structured Query Language) injection is a web security vulnerability that allows an attacker to insert malicious SQL code into a web application’s database query, potentially gaining unauthorized access, manipulating data, or executing arbitrary commands.

78
Q

Stored XSS (Stored Cross-Site Scripting)

A

The malicious script or code is permanently stored on the target website or web application. Whenever a user accesses the affected page, the script is executed.

For example, let’s say there is a vulnerability in the platform’s comment system that does not properly sanitize user input. The attacker takes advantage of this vulnerability by posting a comment containing a malicious script. The script is stored on the platform’s server and becomes part of the comment’s content.

When other users view the affected comment, their web browsers execute the malicious script unknowingly. The script can perform various actions, such as stealing sensitive information (like login credentials or personal data), redirecting users to malicious websites, or even initiating unauthorized actions on behalf of the user.

A

Qualitative refers to a type of analysis or assessment that focuses on non-numerical data and subjective factors to understand and evaluate a subject or situation. It involves gathering and interpreting qualitative data such as observations, opinions, interviews, and descriptions to gain insights, identify patterns, and make subjective judgments. Qualitative analysis often involves a more subjective and interpretive approach compared to quantitative analysis.

102
