opportunities in achieving security goals such as confidentiality, integrity and non repudiation. Key
management is a central component in MANAET security, the purpose of key management is to provide
secure procedures for handling cryptography key materials. Distributed key management is proposed
and deduces the condition under which the key sets distributed to the network nodes to provide MANET

communication. Peer Intermediaries for Key Establishment (PIKE), a class of key establishment
protocols that involves using one or more sensor nodes as a trusted intermediary to facilitate key
establishment. Pike protocols scale sub linearity with the number of nodes in the network and achieving
higher security against node compromise than other protocols. Authenticated Routing for Ad-hoc
Networks (ARAN) is proposed to detect and protect against malicious actions by third parties. ARAN

Wireless sensor networks are made up of number of tiny mobile nodes, which
have the capability of computation, sensing and wireless network communication. The
energy efficiency of each node in such kind of networks is one of the important issues under
consideration. Thus for these networks, sensor nodes life time is basically depends on use of
routing protocols for routing operations in WSN. There are various routing protocols
proposed by different researchers, which are considered as efficient on the basis of
performance of network lifetime and energy scavenging. There are different routing
protocols introduced for WSN such as flat routing protocols, clustering routing protocols,
hierarchical routing protocols etc. On the other hand, there are basically two types of
WSNs, homogeneous and heterogeneous sensor networks. As WSN is vulnerable to different
types of security threats, there are many security methods presented with their own
advantages and disadvantages. Most of security methods are applied only on homogeneous
WSN, but recently some methods were presented to provide the routing security in
heterogeneous WSNs as well. In this paper, the different security threats and Intrusions in
WSNs are presented, with review of different security methods.

This presentation is about the intrusion detection techniques in a mobile ad hoc network. A MANET is an infrastructure-less network and has no central authority to govern the security check if the new node added to the network is trust worthy or not. There are number of security attacks in a MANET and there are number of advantages of a MANET. Most of its applications prove to be a boon when there is a need of a network for communication in a hostile environment and in remote areas. So it must be made secure. Work is still in progress regarding the security of MANET. The migration to wireless network from wired network
has been a global trend in the past few decades. The mobility
and scalability brought by wireless network made it possible in
many applications. Among all the contemporary wireless networks,
Mobile Ad hoc NETwork (MANET) is one of the most
important and unique applications. On the contrary to traditional
network architecture, MANET does not require a fixed network
infrastructure; every single node works as both a transmitter and
a receiver. Nodes communicate directly with each other when they
are both within the same communication range. Otherwise, they
rely on their neighbors to relay messages. The self-configuring
ability of nodes inMANETmade it popular among criticalmission
applications like military use or emergency recovery. However,
the open medium and wide distribution of nodes make MANET
vulnerable to malicious attackers. In this case, it is crucial to
develop efficient intrusion-detection mechanisms to protect
MANET from attacks. With the improvements of the technology
and cut in hardware costs, we are witnessing a current trend of
expanding MANETs into industrial applications. To adjust to such
trend, we strongly believe that it is vital to address its potential
security issues. In this paper, we propose and implement a new
intrusion-detection system named Enhanced Adaptive ACKnowledgment
(EAACK) specially designed for MANETs. Compared
to contemporary approaches, EAACK demonstrates higher malicious-
behavior-detection rates in certain circumstances while does
not greatly affect the network performances.By definition, Mobile Ad hoc NETwork (MANET) is a
collection of mobile nodes equipped with both a wireless
transmitter and a receiver that communicate with each other
via bidirectional wireless links either directly or indirectly.
Industrial remote access and control via wireless networks are
becoming more and more popular these days. One of the
major advantages of wireless networks is its ability to allow
data communication between different parties and still maintain
their mobility. However, this communication is limited to
the range of transmitters. This means that two nodes cannot
communicate with each other when the distance between the
two nodes is beyond the communication range of their own.
MANET solves this problem by allowing intermediate parties
to relay data transmissions. T

Security Key Management Model for Low Rate Wireless Personal Area NetworksCSCJournals
IEEE 802.15.4-based devices networks known by the name of LR-WPAN (Low Rate Wireless Personal Area Network) are characterized by low computation, memory and storage space, and they do not possess an infrastructure. This makes them dynamic and easy to deploy, but in the other hand, this makes them very vulnerable to security issues, as they are low energy so they cant implement current security solutions, and they are deployed in non-secure environments that makes them susceptible to eavesdropping attacks. Most proposed solutions draw out the security of the bootstrapping and commissioning phases as the percentage of existing of an intruder in this time is very low. In this paper, we propose a security model for LR-WPANs based on symmetric cryptography, which takes into account securing the bootstrapping phase, with an analysis of the effectiveness of this proposal and the measures of its implementation.
this ppt is useful for both b.e/b.tech students as well as for mca students. in this ppt u will find different types of security issues in manet and their countermeasures.

Black hole Attack Avoidance Protocol for wireless Ad-Hoc networksijsrd.com
A Mobile Ad-Hoc Network is a collection of mobile nodes or a temporary network set up by wireless mobile nodes moving arbitrary in the places that have no network infrastructure in such a manner that the interconnections between nodes are capable of changing on continual basis. Thus the nodes find a path to the destination node using routing protocols. However, due to security vulnerabilities of the routing protocols, wireless ad-hoc networks are unprotected to attacks of the malicious nodes. Various attacks and one of those attacks is the Black Hole Attack against network integrity absorbing all data packets in the network. Since the data packets do not reach the destination node on account of this attack, data loss will occur. Therefore, it is a severe attack that can be easily employed against routing in mobile ad hoc networks. There are lots of detection and defense mechanisms to eliminate the intruder that carry out the black hole attack. . Virtual Infrastructure achieves reliable transmission in Mobile Ad Hoc Network. Black Hole Attack is the major problem to affect the Virtual Infrastructure. In this paper, approach on analyzing and improving the security of AODV, which is one of the popular routing protocols for MANET. Our aim is to ensuring the avoidance against Black hole attack.
1- Mobile ad hoc networks are formed dynamically by an
autonomous system of mobile nodes that are connected
via wireless links.
2- Multihop communication- node communicate with the
help of two or more node from source to destination.
3- No existing fixed infrastructure or centralized administration –No base station.
4- Mobile nodes are free to move randomly-Network topology changes frequently
5- May Operate as standalone fashion or also can be connected to the larger internet.
6- Each node work as router
Primary Goals of Security in MANET
To assure a reliable data transfer over the communication networks and to protect the system resources a number of security services are classified in five categories:-
1-Authentication:- The process of identifying an individual , usually based on a username and password.
2- Confidentially:- Confidentiality aims at protecting the data from disclosure to unauthorized person.
Network attacks against confidentiality
* Packet capturing
Password attack
Port scanning
Dumpster Diving
Wiretapping
Phishing and Pharming
2-Non repudiation:- Integrity guarantees that a message being transferred is never corrupted.
3- Integrity:- Integrity guarantees that a message being transferred is never corrupted.
network attack against integrity
Salami attack
trust relationship attacks
Man in the middle attack
Session hijacking attacks
4- Availability:- Its ensure that data ,network resources or network services are available to legitimate user when required.
network attack against availability
Denial of services attacks
Distributed denial of services attack
SYN flood attacks and ICMP flood attacks
Electrical power attacks
Server Room environment attacks
Key management
The security in networking is in many cases dependent on proper key management.
Key management consists of various services, of which each is vital for the security
of the networking systems
* Trust model:-Its must determine how much different element in the network can trust each other.
* Cryptosystem:- Public and symmetric key mechanism can be applied .
* Key creation:- It must determine which parties are allowed to generate key to themselves.
* Key storage :- In adhoc network any network element may have to store its own key and possibly key of other element as well.
* Key distribution:- The key management service must ensure that the generated keys are securely distributed to their owners.
A comparative study on different trust based routing schemes in manetijwmn
A mobile ad hoc network is a wireless network in which no infrastructure is available. MANET is a selfconfiguring
network. Due to dynamic nature of MANET it is very challenging work to employ a secure
route. The intermediate nodes cooperate with each other as there is no such base station or access point.
The routing protocols play important role in transferring data. Cryptographic mechanisms are used in
routing protocols to secure data packets while transmitted in the network. But cryptographic techniques
incur a high computational cost and can’t identify the nodes with malicious intention. So, employing
cryptographic techniques in MANET are quite impractical as MANETs have limited resource and
vulnerable to several security attacks. Trust mechanism is used as an alternative to cryptographic
technique. Trust mechanism secures data forwarding by isolating nodes with malicious intention using trust
value on the nodes. In this paper we survey different trust based protocols of MANET and compare their
performances.
IMPACT ANALYSIS OF BLACK HOLE ATTACKS ON MOBILE AD HOC NETWORKS PERFORMANCEijgca
A Mobile Ad hoc Network (MANET) is a collection of mobile stations with wireless interfaces which form a temporary network without using any central administration. MANETs are more vulnerable to attacks because
they have some specific characteristics as complexity of wireless communication and lack of infrastructure. Hence security is an important requirement in mobile ad hoc networks. One of the attacks against network integrity
in MANETs is the Black Hole Attack. In this type of attack all data packets are absorbed by malicious node, hence data loss occurs. In this paper we investigated the impacts of Black Hole attacks on the network
performance. We have simulated black hole attacks using Network Simulator 2 (NS-2) and have measured the packet loss in the network without and with a black hole attacks. Also, we measured the packet loss when the
number of black hole attacks increases.

The peer-reviewed International Journal of Engineering Inventions (IJEI) is started with a mission to encourage contribution to research in Science and Technology. Encourage and motivate researchers in challenging areas of Sciences and Technology.
International Journal of Computational Engineering Research(IJCER) is an intentional online Journal in English monthly publishing journal. This Journal publish original research work that contributes significantly to further the scientific knowledge in engineering and Technology.
Mobile Adhoc Network (MANET) is a self-configuring and infrastructure-less network which consists of mobile devices such as mobiles, laptops, PDA's etc. Because of its lack of infrastructure, wireless mobile communication, dynamic topology, MANET is vulnerable to various security attacks. This survey paper presents an overview of developments of voting and non-voting based certificate revocation mechanisms in past few years. Certificate revocation is an important method used to secure the MANET. Certificate revocation isolates the attacker nodes from participating in network activities by revoking its certificate. Over last few years different schemes are explored for certificate revocation. In concluding section we present the limitations of the current cluster based certificate revocation scheme.
Centralized System in MANET with GRP Protocolijceronline
A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. The network is decentralized, where all network activity including discovering the topology and delivering messages must be executed by the nodes themselves, i.e., routing functionality will be incorporated into mobile nodes.. In this paper routing protocols GRP for mobile ad hoc network with centralized system is checked to know the performance of the network. We will see that, is their any change in the performance of the network if will deploy centralized system in MANET.

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).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.

2. MANET
A Mobile Ad-hoc
network is a wireless
ad-hoc network which
is used to exchange
information.
Each node is willing
to forward data to
other nodes.
Does not rely on fixed
infrastructure.
3. FEATURES
Autonomous terminal: A node may function as both
host and a router.
Distributed Operations: since there is no fixed network
the control and management operations are distributed
among the terminals.
Multi-hop routing: packets should be delivered via one
or more nodes.
.
4. Contd..
Dynamic network topology: As the network
change rapidly, the mobile nodes dynamically
establish routing among themselves i.e. they
form their own network
Fluctuating link capacity: One end-to-end path
can be shared by several sessions.
Light-weight terminal: The MANET nodes are
mobile devices with less CPU processing
capability, small memory size, and low power
storage.
5. PROBLEMS IN MANET:
Routing
Security and Reliability
Quality of Service
Internetworking
Power Consumption
6. SECURITY
A major issue in Mobile ad-hoc network is
“SECURITY”.
Two approaches in protecting mobile ad-
hoc networks
Reactive approach: Seeks to detect security threats
and react accordingly.
Proactive approach: Attempts to prevent an attacker
from launching attacks through various cryptographic
techniques
8. Contd..
Secure multicasting: Is a communication
method where a single data packet can be
transmitted from a sender and replicated
to a set of receivers.
Secure routing: Most MANET routing
protocols are vulnerable to attacks that
can freeze the whole network. Need some
solutions that work even if some nodes
compromised.
9. Contd..
Privacy-aware Routing: Building routing
protocols that prevent intermediate nodes
from performing traffic analysis.
Schemes for minimizing size of crypto-
tags( digital signatures) are needed.
Key Management
security goals in MANET are mainly achieved
through trusted Certificate Authority (CA)
compromised CA can easily damage the
entire network.
10. Contd..
Intrusion detection and response
schemes: Anomaly detection is difficult in
MANETs (ex: types of attacks and their
source). collaborative IDS schemes are
needed.
12. Authentication: A node must know the identity
of the peer node it is communicating with.
Without authentication, an attacker could gain
sensitive information and interfere with other
nodes
Confidentiality: Ensures certain information is
never disclosed to unauthorized entities.
Integrity: Message being transmitted is never
corrupted.
13. Contd..
Non-Repudiation: The sender cannot later deny sending the
information and the receiver cannot deny the reception.
Availability: Nodes should be available for communication at all
times. A node need continue to provide services despite attacks.
E.g.: Key management service.
Detection and Isolation: Require the protocol can identify
misbehaving nodes and render them unable to interfere with
routing.
14. IDS-MANET
IDS: Intrusion detection System which is used to
detect and report the malicious activity in ad hoc
networks.
Ex: Detecting critical nodes using IDS
Intrusion Detection System (IDS) can collect and
analyze audit data for the entire network.
Critical node is a node whose failure or
malicious behavior disconnects or significantly
degrades the performance of the network.
15. Contd..
Packets may be dropped due to network
congestion or because a malicious node is
not faithfully executing a routing algorithm.
Researchers have proposed a number of
collaborative IDS systems.
Some of the schemes are neighbor-
monitoring, trust-building, and cluster-
based voting schemes which are used to
detect and report the malicious activity in
ad hoc networks.
16. CONCLUSION
The research on MANET security is still in
its early stage.
MANET is easily vulnerable to security
attacks than wired networks.
