Intrusion Detection Systems (IDS) still prevail as an important line of defense in modern computing environments. Cloud environment characteristics such resource sharing, extensive connectivity, and agility deploying new applications pose security risks that are increasingly exploited. New technologies like container platforms require IDS to evolve effectively detect intrusive activities these ...
This paper deals with a testing method suitable for SIP infrastructure. The performance testing is an issue of research and no standardized methodology has been adopted yet. We present the main ideas of the methodology that allows for testing the keystone of SIP based infrastructure – the SIP Server – in both SIP Proxy and B2BUA (Back to Back User Agent) configurations. Our methodology has its ...
Developers of SIP mostly concentrated on making SIP to do what no other protocol can do. In a way they failed to consider the weaknesses and dangers. From this realization we did a study on the weaknesses of SIP and SIP signaling in Wireless Networks and Services. From our study we identified Delay and Security as the most severe problems, which we discuss in this paper.
This specification defines a load-control event package for the Session Initiation Protocol (SIP). It allows SIP entities to distribute load-filtering policies to other SIP entities in the network. The load-filtering policies contain rules to throttle calls from a specific user or based on their source or destination domain, telephone number prefix. The mechanism helps to prevent signaling over...
The next generation communication system will provide high quality multimedia service in a more flexible and intelligent manner. In this paper, we propose a new SIP over MPLS network architecture to achieve this goal. To integrate SIP protocol with the traffic engineering function of MPLS network seamlessly and facilitate SIP call setup, the SIP-MPLS traffic aggregation server (TA server) is hi...
The Session Initiation Protocol (SIP) is a text-based protocol for initiating and managing communication sessions. The protocol is extended by the SIP-events notification framework to provide subscriptions and notifications of SIP events. One example of such event notification mechanism is presence, which is expressed in XML documents called presence documents. SIP can be compressed by using Si...

Session Initiation Protocol (SIP) high availability, reliability and redundancy are determined by the ability of the core SIP network components to offer high quality SIP services in the event(s) of high call transactions, link outages, device failures, misconfigurations and security attacks. In this context, load balancers can be used to achieve redundancy and active load balancing of SIP tran...
Many applications are transferred from C/S (Client/Server) mode to P2P (Peer-to-Peer) mode such as VoIP (Voice over IP). This paper presents a new security architecture, i.e. a trustworthy authentication algorithm of peers, for Session Initialize Protocol (SIP) based P2P computer networks. A mechanism for node authentication using a cryptographic primitive called one-way accumulator is proposed...
