Intrusion prevention system (IPS) is software that has all the capabilities of an intrusion detection system and can also attempt to stop possible incidents.
What is IDS?
Software or hardware device
Monitors network or hosts for:
Malware (viruses, trojans, worms)
Network attacks via vulnerable ports
Host based attacks, e.g. privilege escalation
What is in an IDS?
An IDS normally consists of:
Various sensors based within the network or on hosts
These are responsible for generating the security events
A central engine
This correlates the events and uses heuristic techniques and rules to create alerts
A console
To enable an administrator to monitor the alerts and configure/tune the sensors
Different types of IDS
Network IDS (NIDS)
Examines all network traffic that passes the NIC that the sensor is running on
Host based IDS (HIDS)
An agent on the host that monitors host activities and log files
Stack-Based IDS
An agent on the host that monitors all of the packets that leave or enter the host
Can monitor a specific protocol(s) (e.g. HTTP for webserver)

Network Based Intrusion Detection and Prevention Systems: Attack Classificati...researchinventy
Complex and common security attackshave become a common issue nowadays. Success rate of detecting these attacks through existing tools seems to be decreasing due to simple rule-bases Some attacks are too complex to identify for today’s firewall systems.This paper highlights various security attacks classification techniques pertaining to TCP/IP protocol stack, it also covers an existingintrusion detection techniques used for intrusion detection , and features of various open source and commercial Network Intrusion Detection and Prevention (IDPS) tools. Finally paper concludes with comparison and evaluation of an open source and commercial IDPS tools and techniques which are used to detect and prevent the security attacks.
Module 19 (evading ids, firewalls and honeypots)Wail Hassan
An Intrusion Detection System (IDS) is a device or software application that monitors network and/or system activities for malicious activities or policy violations and produces reports to a Management Station. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.
Multi-cluster Kubernetes Networking- Patterns, Projects and GuidelinesSanjeev Rampal
Talk presented at Kubernetes Community Day, New York, May 2024.
Technical summary of Multi-Cluster Kubernetes Networking architectures with focus on 4 key topics.
1) Key patterns for Multi-cluster architectures
2) Architectural comparison of several OSS/ CNCF projects to address these patterns
3) Evolution trends for the APIs of these projects
4) Some design recommendations & guidelines for adopting/ deploying these solutions.
2. An IDS or Intrusion Detection System is a system which is designed to detect unauthorized
access to secure system, like by various hacking method like Cross Site Request Forgery
(CSRF), network sniffing, scripting, SQL injection etc.
As name implies intrusion detection system basically detects possible intrusions or misuse
and alerts the authorized person who monitors the system.
It’s basic motto is to detect if there is nay kind of unwanted interference in the system and
issue some type of alert or warning.
3. To know IDS we should know what is the use of IDS, why use IDS you say? Main purpose of
using IDS is to protect three things which are:
i) Data
ii) Availability
iii) Privacy
None of the system are really protected they may have security loopholes, flaws or it may be
even misused by the authorized insider so main purpose of IDS or Intrusion Detection
System is to identify those intruders and limit the possible damage that could happen.
6. Anomaly based IDS states that intrusions can be detected by monitoring a system for abnormal
patterns of system usage.
Examples for Anomaly Intrusion
• Abnormally high rate of password failures,
• Different login time, location or connection type,
• Login at unusual time,
• Trying to get access of restricted resources,
• Execution of unwanted programs,
7. Merits
• Can detect an attack without previous knowledge about it,
• Can avoid previous unseen attacks
• It can detect abuse of privileges types of attacks which generally do not involve
exploiting any security vulnerabilities,
• It can recognize unusual network traffic based on network packed characteristics.
Demerits
• These generates many false alarms and hence compromise the effectiveness of the IDS,
• Affects Privacy of users,
8. It is also known as signature based detection because it this system It is equipped with a
number of attacks description or we can say signatures and when intrusion occurs it is
matched against the audit data to detect attacks.
These signatures must be updated over time to time because everyday new methods of hacks,
malware and viruses are deployed by intruders in order to compromise system.
9. Merits
• It can be deployed very quickly because there is no need for IDS to learn behavior before
it can be use,
• Its gives freedom to administrator to write their own signature for benefits of
organizational rules and policy,
• Fewer False alarms will be generated in comparisons to other IDS methods
Demerits
• Hackers of Intruders develops new methods frequently to exploit system so they must be
frequently updated with attack signatures,
• Sometimes in order to make system more secure we make tightly defined signatures
which will result in failure of tackling variants of common attacks.
10. Its is based on monitoring activity on the local host computer.
This monitoring can include network traffic to the host or local object like file processes,
services on the host.
It can be used to analyze all the networks traffic transmitted to the computer and pass
only the packets that is safe onto the computer.
It periodically examines the system security logs for suspicious activity.
11. Merits
• Since it exist in host system it can direct access local system resources for intrusion.
• It can also provide detailed information of the state of the system during attack.
• Low resource utilization since it deals with inspection of traffic on local host.
Demerits
• It can get very complex in large networking systems,
• The host may cease to function resulting in a stop on all logging activity
• If the IDS system is compromised and logging still continues to function the trust on
such log data is severely diminished.
12. Network based IDS includes following process
• Deploying sensors at strategic locations,
• Watch for violation of network protocols and unusual connecting patterns,
• Check into data portions of the packets for malicious command sequences,
• Encryption of data portions and header information.
A filter is usually applied to determine which traffic will be discarded or passed on to an
attack recognition module.
13. Merits
• Easy Deployments
• It can be configured to be invisible to attackers,
• Can view intrusive activity that is targeting several hosts,
• Provides greater details into the nature of traffic,
• It can interact with firewall technology to dynamically block recognized intrusion
behaviors.
Demerits
• High speed and large volume monitoring is needed.
14. Therefor an IDS alerts us to the sophisticated attacks described last time.
It helps to detect malicious packets or intrusion action by comparing it with signatures and
rules that was made by observing the intrusive activities form past logs.
