Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

- How to streamline operations with automated policy checks on container images
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

2. Database Definition
A database can be defined as collection
of information organized in such a way
that it can be accessed easily.
Examples are
Tracking customer orders
Maintaining Employees Records.
Maintaining Students Information
3. Terminologies
In studying Databases the following Terminologies
must be clear
Data
This is the fact or facts about specific entity (person, place or thing).
Information
This is the processed facts perceived to be useful by the user.
Field
This is a single item of information or data in entity. E.g. employee
Name
Record
This can be defined as data or group of fields about an
entity. E.g. employee particulars
Subject (relation or table)
This can be defined as a collection of records that are related
to a particular entity. For example, Records for all employees
will make up one subject.
5. Manual systems
Structure
Information can be stored in dedicated room or in separate offices.
Room or office will be furnished with shelves;
Different shelves will hold Records for different subjects.
Records will be stored in hard flat files, each file will carry one record
Each file will have a specific number to identify it.
A person will use the file number to retrieve the specific file (record).
7. File Processing Systems (FPS)
Information stored as groups of records in separate
files
File processing systems consisted of a few data files
and many application programs
Each file called a soft flat file
Flat file contain processed information for one specific
function
Use of programming languages to write applications
Little flexibility
High maintenance
Many limitations
8.
9. Limitations of File Processing Systems
Separate and isolated data
Data redundancy
Program - data interdependence
involving file formats and access
techniques
Difficulty in representing data from the
user’s view
Data inflexibility
10. Database Management systems (DBMS)
A program that allows users to define, create, manipulate,
store, maintain, retrieve, and process the data in a
database in order to produce meaningful information.
Focus on information representation
Data stored as records in various database files that can
be combined to produce meaningful information for users
DBMS controls all functions of capturing, processing,
storing, retrieving data and generates various forms of
data output
Manages access by multiple users and multiple programs
to a common store of data
11.
12. DBMS overcomes all Limitations of FPS.
Eliminates separation and isolation of data
Reduces data redundancy
Eliminates dependence between programs
and data
Allows for representation of data from user’s
view
Increases data flexibility
Superior flexibility and security over
spreadsheet applications
13. Characteristics of a DBMS
Computerized record-keeping system
Contains facilities that allow the user to:
o Add, delete files
o Insert, retrieve, update, delete data
Collection of databases; each can be
used for separate purposes or
combined
14. Functions and Uses of a DBMS
To store data
To organize data
To control access to data
To protect data
To provide decision support
To provide transaction processing
15. Advantages and Disadvantages of a DBMS
• Advantages:
Centralized data reduces management problems
Data redundancy and consistency are controllable
Program - data interdependency is diminished
Flexibility of data is increased
• Disadvantages:
Reduction in speed of data access time
Requires special knowledge
Possible dependency of application programs to specific
DBMS versions
16. Database Administrator
A database administrator (DBA) controls and
manages the database.
Function of a DBA
Make decisions concerning the content of the
database
Plan storage structures and access strategies.
Provides support to users
Defines security and integrity checks
Interprets backup and recovery strategies.
18. Flat databases
A single kind of record with a fixed number
of fields.
a way of organizing all information in a
single table.
suitable for extremely simple
databases.
inherit data redundancy
20. Hierarchical Database
Fields or records structured in nodes
Viewed as branches of an upside-down tree
Each item is subordinate to its parent node
Only one parent per node
The subordinate item is the child node to the parent
If parent node is deleted, all the child nodes are as well
deleted
New parent node must be created before adding a new child
node
Limited by rigid structure
No direct relationships between child nodes
22. Network Database
Also has hierarchical node arrangement
But here child nodes may have more than
one parent node, or a many-to-many
relationship
The interconnected design allows for access
via multiple pathways
24. Relational Database
No pre-determined access paths
Data stored in a collection of columns and
rows called a table, or a relation
Tables may be electronically linked via a
key field containing common data
Easy to add, delete and modify the data and
the table structures
27. Table or Relation
Table will store information for a
particular entity
Table name must be unique
The Table name should be descriptive
Column Name must be unique within
the Table
Rows must be unique
28. Null values
missing or unknown value in a column
of a table
Nulls are not the same as zeros
Most arithmetic operations can be
performed on zero values
nulls must be excluded from
mathematical manipulations
29. Duplicate values
A duplicate value is a value in a column
of a table that exactly matches some
other values within the same column.
30. Changeable values
value in a table that may vary over time.
Most values in most tables are
Changeable
You can prevent changes when it is
desirable to prevent changes in a given
column of a table
32. Rules for Primary key
Must always have a value (null values
are not allowed)
Value should be unique (duplicate
values are not allowed)
Value should not change over time
33. Foreign keys
key which relates the rows of the Table
to other Tables
value can be null,
value can change
value can be duplicated
34. Rule for Foreign keys
Value must refer to the existing primary
key.
