This document discusses basic concepts in computer security. It defines computer security as techniques for ensuring data cannot be read or compromised without authorization, usually through encryption and passwords. The three main goals of computer security are confidentiality, integrity, and availability. Vulnerabilities are weaknesses that can be exploited, and threats are circumstances with potential to cause harm. Common threats include interception, interruption, modification, and fabrication. Controls are protective measures used to reduce vulnerabilities, and physical security and security methods like antivirus software and firewalls can help secure computers.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message

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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

2. WHAT IS COMPUTER SECURITY?
•Computer security is refers to techniques for
ensuring that data stored in a computer cannot
be read or compromised by any individuals
without authorization.
•Most computer security measures involve data
encryption and passwords.
•The purpose of computer security is to device
ways to prevent the weaknesses from being
3. WHAT IS COMPUTER SECURITY?
•We are addressing three important aspects of
any computer-related system such as
confidentiality, integrity, and availability.
4. WHAT IS COMPUTER SECURITY?
•These are the three goals in
computing Security.
1.Confidentiality
2.Integrity
3.Availability
5. THREE GOALS IN COMPUTING SECURITY
•Confidentiality: ensures that computer-related
assets are accessed only by authorized parties.
Confidentiality is sometimes
called secrecy or privacy.
•Integrity: it means that assets can be modified
only by authorized parties or only in authorized
ways.
•Availability: it means that assets are accessible
6. THREE GOALS IN COMPUTING SECURITY
•One of the challenges in building
a secure system is finding the right balance
among the goals, which often conflict.
7. VULNERABILITY
•Vulnerability is a weakness in the security
system.
•Weaknesses can appear in any element of a
computer, both in the hardware, operating
system, and the software.
The types of vulnerabilities we might find as
they apply to the assets of hardware, software,
and data.
•These three assets and the connections among
8. HARDWARE VULNERABILITY
•Hardware is more visible than software, largely
because it is composed of physical objects.
•it is rather simple to attack by adding devices,
changing them, removing them, intercepting the
traffic to them, or flooding them with traffic
until they can no longer function.
9. HARDWARE VULNERABILITY
•other ways that computer hardware can be
attacked physically.
•Computers have been drenched with water,
burned, frozen, gassed, and electrocuted with
power surges.
10. SOFTWARE VULNERABILITIES
•Software can be replaced, changed, or
destroyed maliciously, or it can be modified,
deleted, or misplaced accidentally. Whether
intentional or not, these attacks exploit the
software’s vulnerabilities.
11. SOFTWARE VULNERABILITIES
•Sometimes, the attacks are obvious, as when
the software no longer runs. More subtle are
attacks in which the software has been altered
but seems to run normally.
12. DATA VULNERABILITY
•a data attack is a more widespread and serious
problem than either a hardware or software
attack.
•data items have greater public value than
hardware and software because more people
know how to use or interpret data.
13. THREATS
•A threat to a computing system is a set of
circumstances that has the potential to cause
loss or harm.
•There are many threats to a computer system,
including human-initiated and computer-
initiated ones.
•A threat is blocked by control of a vulnerability.
•We can view any threat as being one of four
14. THREATS
•An interception means that
some unauthorized party has
gained access to an asset.
The outside party can be a
person, a program, or a
computing system.
17. THREATS
•An unauthorized party might create
a fabrication of counterfeit objects on a
computing system.
•The intruder may insert spurious transactions
to a network communication system or add
records to an existing database.
18. ATTACKS
•A human who exploits a vulnerability
perpetrates an attack on the system. An attack
can also be launched by another system, as
when one
•system sends an overwhelming set of messages
to another, virtually shutting down the second
system's ability to function.
19. ATTACKS
•Unfortunately, we have seen this type of attack
frequently, as denial-of-service attacks flood
servers with more messages than they can
handle.
20. CONTROL
•The control is an action, device, procedure or
technique that removes or reduces a
vulnerability.
•We use a control as a protective measure.
•There are so many ways to controle.
21. HOW TO SECURE THE COMPUTER
•There are two ways
1.Physical secure
2.Other secure methods
28. SECURE THE COMPUTER
•Choose a web browser
based on its security and
vulnerabilities because
most malware will come
through via your web
browser
29. SECURE THE COMPUTER
•When setting up, use
strong passwords in your
user account, router
account etc. Hackers may
use dictionary attacks and
brute force attacks.
30. SECURE THE COMPUTER
•When downloading
software (including
antivirus software), get it
from a trusted source
31. SECURE THE COMPUTER
•Install good antivirus
software because Antivirus
software is designed to
deal with modern malware
including viruses, Trojans,
key loggers, rootkits, and
worms.
