Unit 3 system models
The document discusses system modeling as part of the requirements engineering process. It describes different types of models used to represent systems, including context models, behavioral models, data models, and object models. Specific modeling notations are introduced, such as data flow diagrams, state machines, and entity-relationship diagrams. Examples are provided to illustrate modeling concepts for systems like an ATM, order processing, and a microwave oven. The goal of system modeling is to help analysts understand system functionality from different perspectives to communicate requirements.
System modeling
System modeling involves developing abstract models of a system from different perspectives using graphical notations like UML. Models are used during requirements, design, and documentation of a system. There are four main types of system modeling: context modeling defines system boundaries; interaction modeling captures user and component interactions through use cases and sequence diagrams; structural modeling shows system design and architecture using class and generalization diagrams; and behavioral modeling depicts system behavior over time.

SYSTEM MODELLING
System modeling helps analysts understand a system's functionality and communicate with customers. Models abstractly describe systems and create visual representations of proposed databases to ensure all requirements are gathered accurately. Different diagrams like entity relationship diagrams and process flow diagrams illustrate identified business processes, rules, entities, and units. Logical modeling involves gathering information to produce diagrams and reports. Physical modeling designs an actual database according to logical model requirements. Data flow modeling is a mature technique used to provide detailed models of all system processes.
UML DIAGRAMS
A class diagram shows the structure of a system by displaying classes, interfaces, and their relationships. It models the static design view of a system. To create a class diagram, one identifies the relevant elements and responsibilities of each class with a minimum number of attributes. Relationships between classes are also specified. A class diagram can be used to describe system functionality and for object-oriented development. An object diagram represents a snapshot of the system by showing specific object instances and their relationships at a point in time, modeling the static process view. It is used for forward/reverse engineering, understanding object behavior and relationships from a practical perspective.

Structural modeling shows how different entities ("things") are related to each other. It involves identifying objects and classes, defining their attributes and operations, and specifying relationships like generalization, aggregation, and associations between classes. UML notation is commonly used to diagram class structures and relationships. The domain modeling process aims to develop class models that describe real-world entities and their interactions within a problem domain.

System modeling involves creating abstract models of a system from different perspectives, such as context, interactions, structure, and behavior. These models help analysts understand system functionality and communicate with customers. Context models show a system's external environment and relationships. Interaction models, such as use case and sequence diagrams, depict how users and systems interact. Structural models, like class diagrams, represent a system's internal organization. Behavioral models, including activity and state diagrams, illustrate a system's dynamic response to events or data. Model-driven engineering aims to generate implementation from system models.

UML is a modeling language used to visualize, specify, construct, and document software systems. It provides standard graphical notations for modeling structural and behavioral aspects of a system using diagrams. The key UML diagram types are structural diagrams (e.g. class, component), behavioral diagrams (e.g. use case, activity), and interaction diagrams (e.g. sequence, communication). UML was created through the unification of several popular modeling languages in the 1990s and is now managed by the Object Management Group.

System Modelling
This document provides an overview of system modeling. It discusses that system modeling involves developing abstract models of a system from different perspectives, and is commonly done using the Unified Modeling Language (UML). It also describes various UML diagram types used in system modeling like use case diagrams, class diagrams, and state diagrams. Finally, it gives examples of modeling different views of a mental health case management system, including contextual models, interaction models, structural models, and behavioral models.
Ch5 - System Modeling
This document discusses system modeling and different types of models used in system modeling. It covers context models, interaction models, structural models, behavioral models, and model-driven engineering. Some key points include:
- System modeling involves developing abstract models of a system from different perspectives or views. Models are often developed using the Unified Modeling Language (UML).
- Common model types include use case diagrams, sequence diagrams, class diagrams, state diagrams, and activity diagrams.
- Structural models show the organization and structure of a system. Behavioral models show the system's dynamic behavior and responses to events.
- Model-driven engineering is an approach where models rather than code are the primary outputs and code is generated

Firewall - Network Defense in Depth Firewalls
This document discusses key concepts related to network defense in depth. It defines common terms like firewalls, DMZs, IDS, and VPNs. It also covers techniques for packet filtering, application inspection, network address translation, and virtual private networks. The goal of defense in depth is to implement multiple layers of security and not rely on any single mechanism.
Mobile Security - Wireless hacking
This document discusses wireless security and protocols such as WEP, WPA, and 802.11i. It describes weaknesses in WEP such as vulnerabilities in the RC4 encryption algorithm that allow attacks like dictionary attacks. It introduces WPA as an improvement over WEP that uses stronger encryption keys, protocols like TKIP that change keys dynamically, and AES encryption in 802.11i as stronger alternatives. It also discusses authentication methods like 802.1X that distribute unique keys to each user to address issues with shared keys in WEP.
Authentication in wireless - Security in Wireless Protocols
The document discusses authentication protocols for wireless devices. It begins by describing the authentication problem and some basic client-server protocols. It then introduces the challenge-response protocol which aims to prevent replay attacks by including a random number in the response. However, this protocol is still vulnerable to man-in-the-middle and reflection attacks. The document proposes improvements like including an identifier in the hashed response to prevent message manipulation attacks. Overall, the document provides an overview of authentication challenges for wireless devices and the development of challenge-response protocols to address these issues.

Lecture 1 - Getting to know XML
XML FOR DUMMIES
The document is a chapter from the book "XML for Dummies" that introduces XML. It discusses what XML is, including that it is a markup language and is flexible for exchanging data. It also examines common uses of XML such as classifying information, enforcing rules on data, and outputting information in different ways. Additionally, it clarifies what XML is not, namely that it is not just for web pages, not a database, and not a programming language. The chapter concludes by discussing how to build an XML document using editors that facilitate markup and enforce document rules.
Lecture 4 - Adding XTHML for the Web
This document discusses the differences between HTML, XML, and XHTML. It covers how XHTML combines the structure of XML with the familiar tags of HTML. Key points include:
- HTML was designed for displaying web pages, XML for data exchange, and XHTML uses HTML tags with XML syntax.
- XML allows custom tags, separates content from presentation, and is self-describing, while HTML focuses on display.
- Converting to XHTML requires following XML syntax rules like closing all tags, using empty element syntax, proper nesting, and lowercase tags and attribute quotes.
