(001, 002, 003, 004, etc.) Tokens, session IDs, and Passwords are kept in plaintext. Pseudo random session IDs would be a broken authentication counter measure.

Why would an organization offer to use a source code escrow to their customers? Because we want them to see the source code whenever they want to. To ensure the code is tested completely. To make our source code publicly available. So the customer has access to the source code if we go bankrupt.

So the customer has access to the source code if we go bankrupt. Explanation Source code escrow: The deposit of the source code of software with a third party escrow agent. Escrow is typically requested by a party licensing software (the licensee), to ensure maintenance of the software instead of abandonment or orphaning. The software source code is released to the licensee if the licensor files for bankruptcy or otherwise fails to maintain and update the software as promised in the software license agreement.

We have asked a vendor to use a source code escrow What could be a reason we would do that? So we can get the source code if they fail to maintain and update the code. So we can view the source code when we want to. So we can get the source code if we want to break the contract we have with them, because we have found a cheaper alternative. So we can get the source code if we have software errors.

So we can get the source code if they fail to maintain and update the code. Explanation Source code escrow: The deposit of the source code of software with a third party escrow agent.

Which software project management methodology is based on 4 phases we go through over and over? Waterfall Agile. Sashimi.

Spiral. Explanation The spiral model: A risk-driven process model generator for software projects. The spiral model has four phases: Planning, Risk Analysis, Engineering and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model). The baseline spiral, starting in the planning phase, requirements are gathered and risk is assessed. Each subsequent spirals builds on the baseline spiral.

At a meeting with project stakeholders and sponsors, Bob gets asked how a relational database is structured. From these choices, what should Bob answer? Star schema model. A hierarchy model. An object model.. Tables with rows and columns.

Tables with rows and columns. Explanation Relational model: Organizes data into one or more tables (or relations) of columns and rows, with a unique key identifying each row. Rows are also called records or tuples. Generally, each table/relation represents one entity type. The rows represent instances of that type of entity and the columns representing values attributed to that instance.

What is happening when we experience buffer overflows? The buffer overruns its boundaries and overwrites adjacent memory locations. We are not using SSL/TLS. The buffer overruns its boundaries and overwrites adjacent hard disk locations. User session IDs or tokens are stolen.

The buffer overruns its boundaries and overwrites adjacent memory locations. Explanation Buffer overflow (buffer overrun): An anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory locations, happen from improper coding when a programmer fails to perform bounds checking. Buffers are areas of memory set aside to hold data, often while moving it from one section of a program to another, or between programs. Buffer overflows can often be triggered by malformed inputs, if one assumes all inputs will be smaller than a certain size and the buffer is created to be that size, if an anomalous transaction produces more data it could cause it to write past the end of the buffer. If this overwrites adjacent data or executable code, this may result in erratic program behavior, including memory access errors, incorrect results, and crashes. By sending in data designed to cause a buffer overflow, it is possible to write into areas known to hold executable code, and replace it with malicious code.
