Layered Approach for Preprocessing of Data in Intrusion Prevention SystemsEditor IJCATR
Due to extensive growth of the Internet and increasing availability of tools and methods for intruding and attacking
networks, intrusion detection has become a critical component of network security parameters. TCP/IP protocol suite is the defacto
standard for communication on the Internet. The underlying vulnerabilities in the protocols is the root cause of intrusions. Therefor
Intrusion detection system becomes an important element in network security that controls real time data and leads to huge
dimensional problem. Processing large number of packets and data in real time is very difficult and costly. Therefor data preprocessing
is necessary to remove redundant and unwanted information from packets and clean network data. Here, we are focusing on
two important aspects of intrusion detection; one is accuracy and other is performance. The layered approach of TCP/IP model can be
applied to packet pre-processing to achieve early and faster intrusion detection. Motivation for the paper comes from the large impact
data preprocessing has on the accuracy and capability of anomaly-based NIPS. In this paper it is demonstrated that high attack
detection accuracy can be achieved by using layered approach for data preprocessing in Internet. To reduce false positive rate and to
increase efficiency of detection, the paper proposed framework for preprocessing in intrusion prevention system. We experimented
with real time network traffic as well as he KDDcup99 dataset for our research.
It measures lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is helpful in assessing breathing patterns that identify conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD. I createdasas
Net neutrality is the principle that Internet service providers treat all data on the Internet equally, and not discriminate or charge differently by user, content, website, platform, application, type of attached equipment, or method of communication.[4] For instance, under these principles, internet service providers are unable to intentionally block, slow down or charge money for specific websites and online content. This is sometimes enforced through government mandate.

Have you ever wanted a Ruby client API to communicate with your web service? Smithy is a protocol-agnostic language for defining services and SDKs. Smithy Ruby is an implementation of Smithy that generates a Ruby SDK using a Smithy model. In this talk, we will explore Smithy and Smithy Ruby to learn how to generate custom feature-rich SDKs that can communicate with any web service, such as a Rails JSON API.

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
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

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.

9. Common Types of attacks
Reconnaissance-ping sweeps and port scans
Sniffing –capture packet as they travel through the network
Man-in–the-middle-attack: intercepts messages that are intended for
a valid device.
Spoofing –sets up a fake device and trick others to send messages
to it.
Hijacking- taking control of session
Denial of service (DoS) Dynamic DoS (DDoS)attack
10. Trusted Network
Standard defensive-oriented technologies
Firewall-first line of defense
Intrusion Detection
Build TRUST on top of the TCP/IP Infrastructure
Strong authentication
Two factor authentication
Something you have + something you know
Public key infrastructure (PKI)
11. Access control
Access control –
ability to permit or deny the use of an object by a subject
It provide 3 essential services (known as
AAA)-
Authentication-(who can login)
Authorization - (what authorized users can do )
Accountability –(identifies what a user did )
12. Important Steps to Security
• Password Protection
• Protecting the network by filtering Network Access and Traffic (i.e. Firewall)
• Running Security Audits
• Examine and monitor log files
• Use commonense: avoid dumpster divers and social engineers
13. Firewalls
A firewall is a computer, hardware, or even a piece of software that sits between
your network and the Internet, the firewall attempts to regulate and control the flow
of information preventing an array of potential attacks.
A router utilizing Network Address Translation(NAT)
Software firewalls such as Zone Alarm, Kerio Firewall,
Outpost, etc.
Hardware firewalls such as Sonic’s SOHO firewall.
Operating system firewalls Ex.Window XP’s built in filtering .
14. Virtual Private Network
Creates a secure tunnel over a public network
Client-to-firewall , router-to-router , firewall-to-
firewall
VPN protocol standards:
PPTP-(Point-to-Point Tunneling protocol)
L2F -(Layer to Forwarding Protocol)
L2TP-(Layer to tunneling Protocol)
IPSec(Internet Protocol Security)

16. Significance of this project
It makes your computer a router !
And a Gateway router too!!
Benefits:
Test new configurations
New routing policies
New protocols
Don’t disturb the production network
Use cheap PCs instead of expensive routers.
29. conclusion
The Simulator takes the configurations of
the subnet as Input and gives the different
statistics of the routers and links. By
changing the routing algorithms and the
different network configurations and
recording the results we obtain the optimal
algorithm. The optimal algorithm for a
particular network is obtained by analyzing
the results obtained. Simulation helps to
achieve an optimal path that reduces the
cost of routing and helps to maintain
network efficiency very easily.
30. Conclusion And Future Scope
The smaller networks can be analyzed and the
results can be employed in larger networks to
make routing efficient and economic. As the
Simulator has provision for the crashing of
routers, it gives an idea of which path is followed
when a crash occurs. It can be employed in real
networks to increase the performance of routers
and links. As it not feasible in real networks to
test algorithms and then implement a best one,
Routing Simulation System can be helpful in
maintaining Network Security. Hence it is
useful for people who provide networking
services and those who design networks.
