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.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

6. Network classification by their component role
7. Types of servers
3. DEFINITION & APPLICATION
A computer network is defined as the interconnection of
two or more computers. It is done to enable the computers to
communicate and share available resources.
Applications:
Sharing of resources such as printers
Sharing of expensive software’s and database
Communication from one computer to another computer
Exchange of data and information among users via
network
Sharing of information over geographically wide areas.
4. COMPONENTS OF COMPUTER NETWORK
Two or more computers
Cables as links between the
computers
A network interfacing card (NIC)
on each computer
Switches
Software called operating system
(OS)
5. The network provided to the users can be divided into two categories:
• Sharing
• Connectivity
NETWORK BENEFITS
6. Types of resources are:
Hardware: A network allows users to share many
hardware devices such as printers, modems, fax
machines, CD ROM, players, etc.
Software: Sharing software resources reduces the cost
of software installation, saves space on hard disk.
SHARING RESOURCES
7. OTHER BENEFITS OF COMPUTER NETWORK
Increased speed
Reduced cost
Improved security
Centralized software managements
Electronic mail
Flexible access
8. DISADVANTAGES OF NETWORK
High cost of installation
Requires time for administration
Failure of server
Cable faults
10. LOCAL AREA NETWORK (LAN)
LAN is a network which is designed to operate over a small physical area such an office,
factory or a group of buildings.
LAN’s are easy to design and troubleshoot.
Exchange of information and sharing of resources becomes easy because of LAN.
In LAN all machines connected to a single cable.
Different types of topologies such as star, tree, bus, ring etc. can be used.
It is usually a privately owned network.
11. WIDE AREA NETWORK (WAN)
When networks span over a large distance of when the computers to be connected
to each other are at widely separated locations a local network cannot be used. A
wide are network (WAN) is installed.
The communication between different users of WAN is established using
leased telephone lines, satellite links and similar channels.
It is cheaper and more efficient to use the phone network for the link.
Most WAN networks are used to transfer large blocks of data between its users.
12. PERSONAL AREA NETWORK (PAN)
A personal area network is a computer network organized around an
individual person.
It generally consists of a mobile computer, a cell phone or personal a
digital assistant. PAN enables the communication among these devices.
It can also be used for communication among personal devices
themselves for connecting to a digital level network and internet.
The PAN’s can be constructed using wireless or cables.
13. CAMPUS AREA NETWORK (CAN)
The campus area network is made up of an
interconnection of LAN with limited geographical
area.
Network equipment such as switches, routers
and the transmission media i.e. optical fibre etc.
are almost entirely owned by the campus owner.
14. METROPOLITAN AREA NETWORK (MAN)
It is in between LAN & WAN technology that covers the entire city.
It is uses similar technology as LAN.
It can be a single network such as cable TV network, or a measure
of connecting a number of LAN’s or a large networks so that
resources can be shared LAN to LAN as well as device to device.
18. PEER TO PEER NETWORK
In peer to peer network each computer is responsible for making its own
resources available to other computers on the network.
Each computer is responsible for setting up and maintaining its own security for
these resources.
Also each computer is responsible for accessing the required network resources
from peer to peer relationships.
Peer to peer network is useful for a small network containing less than 10
computers on a single LAN.
In peer to peer network each computer can function as both client and server.
Peer to peer networks do not have a central control system. There are no servers
in peer networks.
Peer networks are amplified into home group.
19. ADVENTAGES AND DISADVANTAGES OF PEER TO
PEER NETWORK
Advantages
• Use less expensive
computer hardware
• Easy to administer
• No NOS required
• More built in
redundancy
• Easy setup & low cost
Disadvantages
• Not very secure
• No central point of
storage or file archiving
• Additional load on
computer of resource
sharing
• Hard to maintain
version control
20.
21. CLIENT/SERVER NETWORK
In client-server network relationships, certain computers act as server and other
act as client. A server is simply a computer, that available the network resources
and provides service to other computers when they request it. A client is the
computer running a program that requests the service from a server.
Local are network (LAN) is based on client server network relationship.
A client-server network is one on which all available network resources such as
files, directories, applications and shared devices, are centrally managed and
hosted and then are accessed by client.
Client serve network are defined by the presence of servers on a network that
provide security and administration of the network.
22. ADVENTAGES AND DISADVANTAGES OF CLIENT-
SERVER NETWORK
Advantages
• Very secure
• Better performance
• Centralized backup
• Very reliable
Disadvantages
• Requires professional
administration
• More hardware
intensive
• More software
intensive
• Expensive dedicated
24. TYPES OF SERVERS
File server: These servers provide the services for storing, retrieving and moving
the data. A user can read, write, exchange and manage the files with the help of
file servers.
Printer server: The printer server is used for controlling and managing printing on
the network. It also offers the fax service to the network users.
Application server: The expensive software and additional computing power can
be shared by the computers in a network with the help of application servers.
Message server: It is used to co-ordinate the interaction between users,
documents and application. The data can be used for audio, video, binary, text or
graphic.
Database server: It is a type of application server. It allows the users to access
the centralized strong database.
