SELinux is a method for mandatory access control (MAC) on Linux systems. MAC provides an additional layer of security beyond traditional discretionary access control (DAC) by labeling both subjects like users and objects like files. SELinux policies define which labeled subjects can access which labeled objects. In practice, both DAC and MAC are used together, so even if a SELinux policy allows access, the user still needs the correct file permissions via DAC. When running SELinux, commands like ps -Z and ls -Z can show the security labels on processes and files.

A cookie is information stored on a user's machine by a web server that is returned to the server on subsequent visits. Common uses include storing a user ID to identify users without requiring them to log in again. For example, Amazon assigns users an ID when they make a purchase and stores their information against that ID, sending the ID back as a cookie so their information can be retrieved on future visits using just the ID.
Social Media Forensics for Investigators
With 1.2 billion monthly active users on Facebook alone, it’s not surprising that social media networks can be a rich source of information for investigators. And because Americans spend more time on social media than any other major Internet activity, including email, social media information and evidence is plentiful. You just need to know how to get it.
Finding, preserving and collecting social media evidence often requires some forensic skills, as well as an understanding of the laws that govern its collection and use. It’s important for investigators to be aware of both the possibilities and limitations of social media forensics.

Access control regulates operations on protected data and resources. It aims to control what subjects can do to prevent damage. Access control is provided by operating systems and database management systems. It uses reference monitors to grant or deny access requests from subjects for objects based on access control policies and permissions. Access control mechanisms implement the access control function using permissions or subject/object attributes to make access decisions.

Week No 13 Access Control Part 1.pptx
This document discusses various access control models and concepts. It begins by defining access control as the prevention of unauthorized use of resources, controlling who can access a resource, under what conditions, and what they are allowed to do. It then covers different access control models and concepts in detail including access control matrices, access control lists, capabilities, role-based access control (RBAC), mandatory access control (MAC), and separation of duty constraints. RBAC is described as defining roles and associated permissions rather than assigning permissions directly to users. Hierarchical and static/dynamic separation of duty extensions to the core RBAC model are also summarized.
Protection
This document discusses various concepts related to protection in operating systems. It covers the goals of protection which include preventing unauthorized access and enforcing access policies. The principle of least privilege is introduced which dictates that users and programs be given only necessary privileges. Access control and its basic terminology like objects, access rights and access control policies are defined. Implementation techniques for access control like access matrix, access control lists, capability lists and language-based approaches are described at a high level. The document provides an overview of key protection concepts in operating systems.

This chapter discusses protection in computer systems. It covers the goals of ensuring only authorized access to resources, the principle of least privilege, using access matrices to define access rights across protection domains, and different methods of implementing and revoking access controls, such as capability-based systems and language-based protections. Protection domains group objects and access rights, while access matrices specify the operations each domain can perform on different objects. Various operating systems implement domains and matrices in different ways to enforce access restrictions.

Document level security is important in search based applications to restrict access to confidential documents. There are two main access control models - discretionary access control (DAC) and non-discretionary access control (role based access control). For DAC, the document owner controls access and late binding with an externalized access control list (ACL) stored as a bit array is efficient for dynamic ACLs. For role based access control, early binding with ACLs stored with document objects works well for static roles and ACLs. Caching and optimized ACL representations are important to minimize security filtering delays during search.

Document level security is important in search based applications to restrict access to confidential documents. There are two main access control models - discretionary access control (DAC) and non-discretionary access control. For DAC, the document owner can specify access for each user, while role-based access control uses pre-defined roles. Multiple solutions exist depending on the access control model and how frequently access control lists (ACLs) change. These include early or late binding of ACLs to documents and storing ACLs internally or externally. The optimal solution balances security and search performance.
Ch13 protection
This document discusses protection in operating systems. It covers the goals of protection which include ensuring objects are only accessed by allowed processes. Principles of protection include least privilege and need-to-know. Protection domains and access matrices are used to specify allowed access. Implementation options for access matrices include access lists, capability lists, and lock-key systems. Role-based access control and revocation of access rights are also covered. Capability-based systems like Hydra and Cambridge CAP are described. Finally, language-based protection specifies policies through programming languages.
Performance analysis and troubleshooting using DTrace
The document provides an overview of performance analysis tools like tracing and profiling. It discusses different tracing approaches like print statements, logging frameworks, and debuggers. It introduces DTrace as a dynamic instrumentation tool that allows tracing production systems with zero probe effect. A case study demonstrates using DTrace to analyze NFS latency issues. The document also discusses tracing tools for Linux like ftrace, perf, SystemTap, and eBPF.
Topic 7 access control
The document discusses access control, including definitions, principles, policies, requirements, and basic elements. It covers discretionary access control models, protection domains, UNIX file access control using inodes, traditional UNIX controls like setuid and sticky bits, and newer access control lists in UNIX.
Oerating system project
The document discusses file system protection and access control. It describes how multi-user systems require mechanisms beyond physical security, like access control lists, to protect files. Access control lists associate users with permitted access levels (read, write, etc.) for each file. While detailed, access lists can become lengthy. Most systems simplify this using the owner, group, and universe classifications with permission bits for each. For example, in Unix systems files have separate permission bits for the owner, group and others which control read, write and execute access. The document also provides examples of access control list usage and management in different operating systems.
Services and system calls
The open system call opens a file and returns a file descriptor. It takes a file path, access flags, and optional mode as arguments. The library function open() wraps the system call. It returns the file descriptor on success or -1 on error and sets errno. The program then uses the descriptor for read, write, or other file operations.
Licão 04 permissions
User, group, and file permission information in Linux is stored in three key files: /etc/passwd, /etc/shadow, and /etc/group. These files can be managed using commands like useradd, usermod, userdel, groupadd, and groupmod to create, modify, and delete users and groups. File permissions in Linux include read, write, and execute for both files and directories and are controlled using commands like chown, chgrp, and chmod to set ownership, group membership, and access levels for users.
Se linux course1
This document provides an overview of SELinux including its history and development. It was originally created by the NSA as a way to implement mandatory access controls on Linux systems. Key points discussed include how SELinux implements the Flask architecture and uses security contexts, domains, and a policy language to enforce access controls at a more granular level than traditional Linux permissions. The document also covers SELinux file system labeling and different object classes.
Protection Domain and Access Matrix Model -Operating System
This document discusses protection and security in operating systems. It covers authorization, authentication, encryption, and how operating systems control user access to system resources by deciding which users can access which resources. Protection deals with access to system resources and determines which files can be accessed by special users. Protection domains specify the resources a process can access and the operations it can perform on those resources. The access matrix model represents the protection state of a system using a matrix with rows for domains and columns for objects to define the access rights for each domain-object pair.
Ppt linux
The document discusses Linux security concepts including user accounts, file permissions, groups, auditing, and PAM authentication. It covers the three layers of the Linux OS - the kernel layer, system layer, and user layer. The kernel layer houses core OS resources while the system and user layers provide interfaces and services to users and applications. Access is controlled through permissions assigned to files and directories for different user categories. Security features like auditing and PAM help enforce access controls and authenticate users.
Least privilege, access control, operating system security
The document discusses principles of least privilege and access control concepts in operating system security. It defines security goals of confidentiality, integrity and availability known as the CIA triad. The principle of least privilege aims to limit a process's privileges to only those necessary for its execution. Access control concepts include discretionary access control where owners control access, and mandatory access control defined by security labels. A reference monitor provides complete mediation, is tamperproof, and verifiable to securely enforce access policies.

Introduction of System Call
In computing, a system call is the programmatic way in which a computer program requests a service from the kernel of the operating system it is executed on. A system call is a way for programs to interact with the operating system. A computer program makes a system call when it makes a request to the operating system’s kernel. System call provides the services of the operating system to the user programs via Application Program Interface(API). It provides an interface between a process and operating system to allow user-level processes to request services of the operating system. System calls are the only entry points into the kernel system. All programs needing resources must use system calls.
Services Provided by System Calls :
Process creation and management
Main memory management
File Access, Directory and File system management
Device handling(I/O)
Protection
Networking, etc.
Unix system protection and history features
The document discusses the history and design of the UNIX operating system and its approach to system protection and security. Key points include:
- UNIX was developed in the 1960s and used a small kernel design with user processes and a standard API for portability. It aimed to enable sharing of systems between multiple users.
- Security in UNIX focused on access control and protection between the kernel and user processes via mechanisms like passwords, protection rings, and access control lists associated with files.
- The UNIX protection system specified access permissions for users, groups and others on files and directories via owner, group and other mode bits to control read, write and execute permissions.
04-1-Linux.ppt
The document provides an introduction to the Linux operating system, explaining that it allows multiple users to be logged in simultaneously and runs processes separately using the kernel. It describes the directory and file system structure, including inodes that contain metadata for each file, and how permissions are assigned to users, groups, and others for access to files based on read, write and execute permissions. Finally, it covers how to view and set file permissions using symbolic modes like chmod and absolute octal modes.
Software Development Life Cycle
The document outlines the program development cycle, which involves designing the program, writing methods to implement the design, testing the methods, and debugging any errors found. It describes each step in more detail: in the design step, the problem is broken down into a series of steps using pseudocode or a flowchart; methods are then written to reflect these steps; testing ensures the program meets its intended purpose without errors or inefficiencies; and debugging identifies and corrects any logical errors in the program's instructions or implementation.
Variable Scope
Variable scope refers to the visibility and lifetime of variables. Local variables defined inside a function are only visible and accessible within that function. They are destroyed when the function exits. Global variables defined outside of functions can be accessed by any function, but it is generally better practice to pass variables between functions rather than using global variables. When updating a global variable within a function, the global keyword must be used to specify that the variable refers to the global one rather than creating a local one of the same name.

When updating a global variable within a function, the global keyword must be used to specify that the variable refers to the global one rather than creating a local one of the same name.
Returning Data
This document discusses function returns in programming. It explains that the return statement is used to end a function's execution and return a value to the calling statement. A function can return a value or expression, and any statements after a return will not be executed. The document also demonstrates how to declare a basic return function and call a function to invoke it and use the returned value.
Intro to Functions
Functions allow code to be broken into reusable segments that perform well-defined single tasks. A function definition includes the function name, body, return value if any, and parameter list. Functions are declared using the def keyword followed by the function name and parameters in parentheses. To call a function, the function name and any parameters are written in parentheses. Functions must be defined before they are called.
Introduction to GUIs with guizero
Here are the answers to your checkpoint questions:
1. An event loop constantly checks for any interactions from the user, like button clicks, text input, etc. It listens for these "events" and allows the program to respond to user actions.
2. The 3 minimum lines of code to create a GUI App are:
- Import App class from guizero
- Create App object
- Call display() on the App object
3. Widgets are the individual components or elements that make up a GUI, like labels, buttons, text boxes, etc. They are used to display information and get input from the user.
Function Parameters
This document discusses function parameters in Python. It explains that parameters hold the values passed into a function as arguments. Parameters act as variables that accept the values passed during a function call. Functions can have multiple parameters, and the number and order of arguments passed must match the function definition. Arguments are passed by value, so changes to a parameter do not affect the original argument. A function can return multiple values using return, and functions themselves can be passed as parameters to other functions.
Nested Loops
A nested loop is a loop inside the body of another loop. The document provides an example of a nested for loop that prints the product of the row and column indexes. It explains that the inner loop completes all its repetitions for each repetition of the outer loop. Nested loops are necessary when a task must be repeated that itself performs a repetitive operation. The document then provides an example of using nested loops to simulate a digital clock, with one loop to track hours, one for minutes, and one for seconds.
Conditional Loops
The while loop causes statements to repeat as long as a boolean condition is true. It executes 0 or more times before terminating. It is called a conditional loop because the loop is controlled by a condition. The while loop checks the condition before entering the loop body. It is well suited for situations where the number of iterations is unknown or depends on logical inputs. Key aspects of a while loop include the condition statement, initializing and updating counters to control loop execution, and using print statements to debug the loop.
Introduction to Repetition Structures
This document introduces looping structures in programming. There are several types of loops that allow code to be repeated, including for, while, and do-while loops. For loops are well-suited for problems that require iterating a specific number of times using a counter variable. The key components of a for loop are an initialization expression, a test expression, and an update expression. For loops iterate through code while the test expression is true, allowing efficient repetition of tasks like summing values or prompting a user multiple times.
Input Validation
Input validation is important to prevent incorrect or invalid values from being entered into an application which could lead to user frustration or security issues. Exceptions handle errors and unexpected conditions during program execution. Common exceptions include ImportError, ValueError, and IOError. The try-except block allows code to be executed within the try statement and exceptions raised to be handled in the except block through predefined or custom exceptions.
Windows File Systems
The document discusses Microsoft file structures. It explains that sectors are grouped into clusters to store files, and that clusters are numbered sequentially starting at 0 in NTFS and 2 in FAT. The Master Boot Record stores partition information, and files deleted in FAT have their directory entry marked with a sigma while files deleted in NTFS are removed from the Master File Table listing. The Master File Table in NTFS tracks file metadata in records containing attribute IDs.
Nesting Conditionals
We can nest conditional statements inside one another to have multiple decision structures test different situations that lead to a single outcome. This involves placing one if/else statement inside another. The inner conditional will only execute if the outer one is false. Nested conditionals allow evaluating multiple options in sequence until a condition is true, at which point the nested structure stops. Logical errors can occur if more than one else statement is included.
Conditionals
Boolean values represent true and false concepts used in computations, named after George Boole. Programs sometimes need to conditionally execute instructions based on decisions. A conditional or decision structure uses an if statement to check a Boolean condition and execute code if true. Operators like ==, <, > are used to form conditional expressions. Conditionals can be nested to check multiple situations. An else statement complements an if statement, executing code if the if statement is false.

It discusses why Python is a useful language, how Python code is interpreted, the basic parts of a Python program including modules and main code, using comments and whitespace for readability, importing common modules like time and GPIOZero for working with times and LEDs, and basic expressions. Key terms defined include objects, modules, functions, and manipulating GPIO pins to control LEDs.
Variables and Statements
Variables allow storing and reusing data in memory. They come in different types like strings, integers, and floats. Variables are declared, initialized by assigning a starting value, and can be reassigned new values. Programming statements are complete actions made up of expressions like initializing or assigning variables, mathematical equations, or conditionals.
Variables and User Input
This document discusses different types of variables used by shells including environmental variables, positional parameters, and user-defined variables. It also covers getting input from users. There are three main types of variables: environmental variables which provide system information to shells, positional parameters which store command line arguments, and user-defined variables which are created and assigned values by users. The read command is used to get input from users and store it in variables.
Intro to Python
This document provides an introduction to the Python programming language. It discusses that Python is an object-oriented and general purpose language used for tasks like web search, gaming, finance, and data analytics. It can be run through a command prompt, text file, or integrated development environment. The document reviews key Python concepts like its interpreted nature, program structure, modules, expressions, printing, and manipulating time and LEDs through importing modules.
Raspberry Pi
The Raspberry Pi is an inexpensive credit card-sized computer originally designed for education to allow schools to incorporate more computer programming. It was also quickly adopted by hobbyists for projects due to its small size and low cost. The document then provides information on why Raspberry Pis are useful, what types of projects can be built including game systems, assistants, weather stations and robots, and how components like breadboards, LEDs, resistors, jumper wires, and GPIO pins can be used in Raspberry Pi projects.
Hardware vs. Software Presentations
Hardware refers to the physical components of a computer like the monitor, keyboard, and storage devices. Software refers to programs and instructions that are not physical objects. A computer needs both hardware and software to function, with the hardware providing the basic components and structure and software providing instructions to operate the hardware and perform tasks. Common types of software include operating systems, which facilitate communication between the user and hardware, and applications, which allow users to perform specific tasks.
Block chain security
Blockchain security works by having each transaction verified as a digital "block" before entering the system. Computers on the network compete to solve cryptographic puzzles to validate blocks and add them to the blockchain in a verifiable order. This process cuts down on fraud while allowing transactions to occur safely and quickly in a decentralized way. Blockchain has many uses including cryptocurrency, supply chains, financial services, and more.

Community Skills Building Workshop | PMI Silver Spring Chapter | June 12, 2024
Community Skills Building Workshop | PMI Silver Spring Chapter | June 12, 2024Hector Del Castillo, CPM, CPMM
We recently hosted the much-anticipated Community Skill Builders Workshop during our June online meeting. This event was a culmination of six months of listening to your feedback and crafting solutions to better support your PMI journey. Here’s a look back at what happened and the exciting developments that emerged from our collaborative efforts.
A Gathering of Minds
We were thrilled to see a diverse group of attendees, including local certified PMI trainers and both new and experienced members eager to contribute their perspectives. The workshop was structured into three dynamic discussion sessions, each led by our dedicated membership advocates.
Key Takeaways and Future Directions
The insights and feedback gathered from these discussions were invaluable. Here are some of the key takeaways and the steps we are taking to address them:
• Enhanced Resource Accessibility: We are working on a new, user-friendly resource page that will make it easier for members to access training materials and real-world application guides.
• Structured Mentorship Program: Plans are underway to launch a mentorship program that will connect members with experienced professionals for guidance and support.
• Increased Networking Opportunities: Expect to see more frequent and varied networking events, both virtual and in-person, to help you build connections and foster a sense of community.
Moving Forward
We are committed to turning your feedback into actionable solutions that enhance your PMI journey. This workshop was just the beginning. By actively participating and sharing your experiences, you have helped shape the future of our Chapter’s offerings.
Thank you to everyone who attended and contributed to the success of the Community Skill Builders Workshop. Your engagement and enthusiasm are what make our Chapter strong and vibrant. Stay tuned for updates on the new initiatives and opportunities to get involved. Together, we are building a community that supports and empowers each other on our PMI journeys.
Stay connected, stay engaged, and let’s continue to grow together!

DAC vs. MAC • In DAC, a user’s access to a file is controlled by what discrete permissions are set on the file. • In MAC, a user’s access to a file is controlled by evaluating the user’s label and the file’s label and looking at the rules which define the access • In practice, DAC and MAC are used together. • If a file is r—r—r--, the user can’t write to it even if a policy in SELinux grants access
- 6. How does this work in practice? • Consider the process httpd • ls –Z on /usr/sbin/httpd returns system_u:object_r:httpd_exec_t:s0 • Four fields – User – Role – Type – Level
- 7. User:Role:Type:Level • User field groups types of users or roles • Likely values in this field are user_u, system_u, or root
- 8. User:Role:Type:Level • Role field on a file is always object_r • Relevant when labeling processes • Possible to design policies to specify which roles have access to which types – this would be Roles Based Access Control (RBAC) • Examples roles are sysadm_r, staff_r, secadm_r
- 9. User:Role:Type:Level • Type field is which most policy rules are based around • Think “what subjects have access to which types”
- 10. User:Role:Type:Level • MultiLevelSecurity (MLS) field • Normally displaying s0,s1,s2, etc • Might be configured to display PatientRecord, CompanyConfidential,Public
- 11. What to remember • SELinux has three forms of access control – Type Enforcement(TE) – Role-Based Access Control (RBAC) – Multi-Level Security (MLS) • By default access is Denied
- 12. In use… • $ps –Z to see info for processes • $ls –Z to see info for files • $chcon to change ( chcon –v –type=user_t filename)
