Study Notes
Lecture 7: Unix Command Utilities
-
Overview:
- Revision
- Pathname
- Copy, Move and Replace
- Permission Modification
-
Creating a file:
- Two methods:
catutility andtouchcommand.
- Two methods:
-
Displaying a text file:
- The
catutility displays the contents of a text file.
- The
-
Deleting a file:
- The
rm(remove) command is used to delete a file.
- The
-
Deleting a directory/folder:
rmdir(remove directory) is used to delete an empty directory.- Cannot delete a directory containing files. First delete the files.
- The
-roption withrmis used for recursive deletion of directories and their contents.
-
Relative Pathname:
- Traces a path from the working directory to a file.
- Any pathname not starting with the root directory (/) is relative.
- Useful for navigating through multiple directories.
-
Absolute Pathname:
- Starts with the root directory (/).
- Used to specify the precise location of a file or directory from the root.
-
Copy, Move and Rename:
cpcommand copies files/directories:cp file1 [Directory Path]cp -r folder1 [Directory Path]
mvcommand moves/renames files/directories:mv file1 [Directory Path]mv file1 [Directory Path]/file2(renames)mv file1 file2(renames)
-
Access Permission:
- Three types of users: owner, group, other.
- Each user can access a file in three ways: read(r), write(w), execute(x)
- Three types of users * three ways = nine possible ways to access files.
-
lsutility with -l and -g options:ls -ldisplays detailed information about files.ls -lglists files including info on the file group permissions.
-
chmodCommand:- Modifies file permissions.
- Symbolic notation and octal numbers are common ways to represent permissions.
chmod u=rwx,g=rx,o=r file1(gives read,write,execute to user; read & execute to group; read to others)chmod 754 file1(same permissions as above expressed numerically)
Lecture 8: GREP and Aliasing
-
Regular Expressions:
- The ability to match a string of text with flexibility and conciseness. (single char, word, sentence, or patterns)
-
GREP Command:
- Prints lines matching a regular expression.
grep "text" filenamesearches for "text" within the file.- Using
-wfor whole word matches avoids partial matches. - Using
-ifor case insensitive searching. - Using
-ndisplays the line numbers of matching lines.
-
The
-Aoption:- Displays lines that come after the matched lines (N lines)
-
The
-Boption:- Displays lines before the matched lines (N lines)
-
The
-Coption:- Displays lines surrounding the matched lines (N lines before and after)
-
The
-ooption:- Prints only matching strings, not the entire matching lines.
-
Aliasing:
- Shortnames for a command (or series of commands)
Lecture 9: Active Directory Domain Services (AD DS)
-
Identity and Access (IDA):
- Stores info on users, groups, computers, etc.
- Identifies entities performing actions on a server using unique IDs.
-
AD data store:
- A centralized, globally accessible repository for identities.
- Managed on domain controllers performing the AD DS role.
-
IDA Responsibilities:
- Authentication (Kerberos).
- Access Control (ACLs—security policies).
-
IDA Technologies Supported by AD:
- Identity management,
- Application Integration and configuration,
- Trust and Access control, -Integrity and secure access,
- Partnership with other systems enabling Single sign-on (SSO) .
-
Active Directory Domain Services (AD DS):
- A centralized repository for identity management.
- Uses Group Policy to provide authentication and authorization services.
- Enables users to find any component in the directory by searching.
-
Application Directory Lightweight Directory Services (AD LDS):
- A standalone version of AD storing and replicating only application related information.
-
Active Directory Certificate Services (AD CS):
- Set up a Certificate Authority for issuing digital certificates.
-
Active Directory Rights Management Services (AD RMS):
- Information-protection technology enabling policy templates for allowed and disallowed access.
-
Active Directory Federation Services (AD FS):
- Enables organizations to extend identity and access controls across multiple platforms and trusted partners, enabling single sign-on (SSO).
-
Beyond IDA:
- AD provides comprehensive features like schema management, policy-based administration, and replication services for distributed network environments.
-
Schema:
- A set of rules defining allowed object classes and attributes. (e.g. User objects with name and password attributes.)
-
Policy-based administration:
- Provides a central configuration point for settings deployed across multiple systems. (e.g. group policies.)
-
Replication Services:
- Copies data (including the directory itself) across disparate network segments to ensure consistency and availability.
-
Global Catalog:
- Enables querying AD and locating objects within the data store.
-
Components of AD Infrastructure:
- Active Directory data store
- Domain controller
- Domain
- Forest
- Functional levels
- Organizational units (OUs)
- Sites
-
Active Directory Data Store:
- Centralized directory stored on domain controllers.
- Contains schema, configuration, global catalog, and domain naming context.
-
Domain Controller (DC):
- Servers that provide AD services.
- Run the Kerberos Key Distribution Center (KDC).
-
Domain:
- A group of computers and users.
- The scope of administrative policies, such as password complexity and account lockout policies.
-
Forest:
- A collection of one or more domains that share the same configuration and schema.
- Defines a security boundary within an organization.
- A collection of one or more domains that share the same configuration and schema.
-
Tree:
- A hierarchical grouping of domains based on their DNS names within a forest.
-
Functional Level:
- Defines the AD functionality and compatibility in a forest. (Windows 2000 native, Windows 2003 or Windows 2008).
-
Organizational Unit (OU):- Container for objects, scope for object management; groups policies (GPOs) can be linked to OUs.
-
Sites:
- Represent a portion of the enterprise where network connectivity is optimal, defining replication scope.
