Computer security threats & prevention,Its a proper introduction about computer security and threats and prevention with reference. Have info about threats and their prevention.
Network Security consists of the provisions and policies adopted by a network
administrator to prevent and monitor unauthorized access, misuse, modification,
or denial of a computer network and network-accessible resources. Network
security involves the authorization of access to data in a network, which is
controlled by the network administrator. Users choose or are assigned an ID and
password or other authenticating information that allows them access to
information and programs within their authority.
Being aware of online and malware threats is the first step to computer security. In this presentation, we help you understand:
a. Importance of computer security
b. Consequences of ignoring computer security
c. Types of threats that can harm your computer
d. Measures to take to keep your computer safe

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

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.

16. Outline
• Attacks, services and mechanisms
• Security attacks
• Security services
• Methods of Defense
• A model for Internetwork Security
• Internet standards and RFCs
17. Background
• Information Security requirements have
changed in recent times
• Traditionally provided by physical and
administrative mechanisms
• Computer use requires automated tools to
protect files and other stored information
• Use of networks and communications links
requires measures to protect data during
transmission
18. Definitions
• Computer Security - generic name for the
collection of tools designed to protect data
and to thwart hackers
• Network Security - measures to protect
data during their transmission
• Internet Security - measures to protect
data during their transmission over a
collection of interconnected networks
19. Aim of this Course
• Our focus is on internet security
• Consists of measures to deter,
prevent, detect, and correct security
violations that involve the transmission of
information
• Requirements seem straightforward,
but the mechanisms used to meet
them can be quite complex …
20. Services, Mechanisms, Attacks
• Need systematic way to define
requirements
• Consider three aspects of
information security:
– security attack
– security mechanism
– security service
• Consider in reverse order
21. Security Service
• Is something that enhances the security of the
data processing systems and the information
transfers of an organization
• Intended to counter security attacks
• Make use of one or more security mechanisms to
provide the service
• Replicate functions normally associated with
physical documents e.g.
– have signatures or dates
– need protection from disclosure, tampering, or
destruction
– be notarized or witnessed
– be recorded or licensed
22. Security Mechanism
• A mechanism that is designed to detect,
prevent, or recover from a security attack
• No single mechanism that will support all
functions required
• However one particular element underlies
many of the security mechanisms in use:
cryptographic techniques
• Hence our focus is on this area
23. Security Attack
• Any action that compromises the security
of information owned by an organization
• Information security is about how to
prevent attacks, or failing that, to detect
attacks on information-based systems
• Have a wide range of attacks
• Can focus on generic types of attacks
– Note: often threat & attack mean same
25. Security Attacks
• Interruption: This is an attack on
availability
• Interception: This is an attack on
confidentiality
• Modification: This is an attack on
integrity
• Fabrication: This is an attack on
authenticity
27. Summary: Attacks, Services
and Mechanisms
• Security Attack: Any action that
compromises the security of information.
• Security Mechanism: A mechanism that is
designed to detect, prevent, or recover from a
security attack.
• Security Service: A service that enhances
the security of data processing systems and
information transfers. A security service
makes use of one or more security mechanisms
28. OSI Security Architecture
• ITU-T X.800 Security Architecture
for OSI
• Defines a systematic way of defining
and providing security requirements
• For us it provides a useful, if
abstract, overview of concepts we will
study
29. Security Services
• X.800 defines it as: a service provided by a
protocol layer of communicating open
systems, which ensures adequate security
of the systems or of data transfers
• RFC 2828 defines it as: a processing or
communication service provided by a
system to give a specific kind of protection
to system resources
30. Security Services (X.800)
• X.800 defines security services in 5 major
categories
– Authentication - assurance that the communicating
entity is the one claimed
– Access Control - prevention of the unauthorized use of
a resource
– Data Confidentiality –protection of data from
unauthorized disclosure
– Data Integrity - assurance that data received is as sent
by an authorized entity
– Non-Repudiation - protection against denial by one of
the parties in a communication
31. Security Services
• Confidentiality (privacy)
• Authentication (who created or sent the data)
• Integrity (has not been altered)
• Non-repudiation (the order is final)
• Access control (prevent misuse of resources)
• Availability (permanence, non-erasure)
– Denial of Service Attacks
– Virus that deletes files
32. Security Mechanisms
(X.800)
• Specific security mechanisms:
– Encipherment: Converting data into form that is
not readable
– Digital signatures: To check authenticity and
integrity of data
– Access controls: Enforcing access rights to
resources
– Data integrity
– Authentication exchange
– Traffic padding: Insertion of bits to frustrate
traffic analysis
– Routing control: Selection of secure routes
– Notarization: Use of trusted third party for
data exchange
33. Security Mechanisms (X.800)
• Pervasive security mechanisms:
– trusted functionality: percieved to be
correct with respect to some criteria
– security labels:
– event detection: detection of security
relevant events
– security audit trails:
– security recovery:
34. Classify Security Attacks as
• Passive attacks - eavesdropping on, or
monitoring of, transmissions to:
– obtain message contents, or
– monitor traffic flows
• Active attacks – modification of data
stream to:
– masquerade of one entity as some other
– replay previous messages
– modify messages in transit
– denial of service
43. Model for Network Security
• Using this model requires us to:
– design a suitable algorithm for the security
transformation
– generate the secret information (keys) used by
the algorithm
– develop methods to distribute and share the
secret information
– specify a protocol enabling the principals to use
the transformation and secret information for
a security service
45. Model for Network Access
Security
• Using this model requires us to:
– select appropriate gatekeeper functions
to identify users
– implement security controls to ensure
only authorised users access designated
information or resources
• Trusted computer systems can be
used to implement this model
46. Methods of Defense
• Encryption
• Software Controls (access limitations
in a data base, in operating system
protect each user from other users)
• Hardware Controls (smartcard)
• Policies (frequent changes of
passwords)
• Physical Controls
47. Internet standards and
RFCs
• The Internet society
– Internet Architecture Board (IAB)
– Internet Engineering Task Force (IETF)
– Internet Engineering Steering Group
(IESG)
48. Summary
• Have considered:
– computer, network, internet security
def’s
– security services, mechanisms, attacks
– X.800 standard
– models for network (access) security
