Got SIEM? Now what? Getting SIEM Work For YouAnton Chuvakin
Got SIEM? Now what? Making SIEM work for you!
Dr Anton Chuvakin
SANS 2010
Security Information and Event Management (SIEM) as well as log management tools have become more common across large organizations in recent years. SIEM and log management have also been a topic of hot debates. In fact, you organization might have purchased these tools already. However, many who acquired SIEM tools have realized that they are not ready to use many of the advanced correlation features, despite promises that "they are easy to use." So, what should you do to achieve success with SIEM? What logs should you collect? Correlate? Review? How do you use log management as a step before SIEM? What process absolutely must be built before SIEM purchase becomes successful. Attend this session to learn from the experience of those who did not have the benefit of learning from other's mistakes. Also, learn a few tips on how to "operationalize" that SIEM purchase you've made.

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.

Computer Networks
Communication Model
Transmission Modes
Communication Types
Classification Of Computer Networks
By Scale
By Structure
By Topology
Network Media
Internetworking
3. Computer Network
A computer network is a group of interconnected
computers.
It allows computers to communicate with each other and
to share resources and information.
First Network : The Advanced Research Projects Agency
(ARPA) funded the design of the "Advanced Research
Projects Agency Network" (ARPANET) for the United
States Department of Defense
10. Local Area Network (LAN)
Contains printers, servers and computers
Systems are close to each other
Contained in one office or building
Organizations often have several LANS
11. Wide Area Networks (WAN)
Two or more LANs connected
Over a large geographic area
Typically use public or leased lines
Phone lines
Satellite
The Internet is a WAN
12. Metropolitan Area Network (MAN)
Large network that connects different
organizations
Shares regional resources
A network provider sells time
13. Campus Area Networks (CAN)
A LAN in one large geographic area
Resources related to the same
organization
Each department shares the LAN
14. Personal Area Network (PAN)
Very small scale network
Range is less than 2 meters
Cell phones, PDAs, MP3 players
16. Client/Server network
Nodes and servers share data roles
Nodes are called clients
Servers are used to control access
Database software
Access to data controlled by server
Server is the most important computer
17. Peer to peer networks (P2PN)
All nodes are equal
Nodes access resources on other nodes
Each node controls its own resources
Most modern OS allow P2PN
Distributed computing is a form
Kazaa
20. BUS
Also called linear bus
One wire connects all nodes
Terminator ends the wires
Advantages
Easy to setup
Small amount of wire
Disadvantages
Slow
Easy to crash
21. STAR
All nodes connect to a hub
Packets sent to hub
Hub sends packet to destination
Advantages
Easy to setup
One cable can not crash network
Disadvantages
One hub crashing downs entire network
Uses lots of cable
Most common topology
22. RING
Nodes connected in a circle
Tokens used to transmit data
Nodes must wait for token to send
Advantages
Time to send data is known
No data collisions
Disadvantages
Slow
Lots of cable
23. MESH
All computers connected together
Internet is a mesh network
Advantage
Data will always be delivered
Disadvantages
Lots of cable
Hard to setup
26. Twisted-pair cabling
Most common LAN cable
Called Cat5 or 100BaseT
Four pairs of copper cable twisted
May be shielded from interference
Speeds range from
1 Mbps to 1,000 Mbps
27. Coaxial cable
Similar to cable TV wire
One wire runs through cable
Shielded from interference
Speeds up to 10 Mbps
Nearly obsolete
28. Fiber-optic cable
Data is transmitted with light pulses
Glass strand instead of cable
Immune to interference
Very secure
Hard to work with
Speeds up to
100 Gbps
29. Wireless Media
Data transmitted through the air
LANs use radio waves
WANs use microwave signals
Easy to setup
Difficult to secure
30. Internetwork
An Internetwork is the connection of two or more
distinct computer networks or network segments
via a common routing technology.
Any interconnection among or between public,
private, commercial, industrial, or governmental
networks may also be defined as an
internetwork.
31. Internetwork
Intranet
Extranet
An intranet is a set of networks, using the Internet Protocol and IP-based tools
such as web browsers and file transfer applications, that is under the control of a
single administrative entity.
Most commonly, an intranet is the internal network of an organization
An extranet is a network or internetwork that is limited in scope to a single
organization or entity but which also has limited connections to the networks of
one or more other usually, but not necessarily, trusted organizations or entities
by definition, an extranet cannot consist of a single LAN; it must have at least
one connection with an external network.
Internet
The Internet consists of a worldwide interconnection of governmental, academic,
public, and private networks based upon the networking technologies of the
Internet Protocol Suite.
It is the successor of the Advanced Research Projects Agency Network
(ARPANET) developed by DARPA of the U.S. Department of Defense.
The Internet is also the communications backbone underlying the World Wide
Web (WWW).
