Viewpoints
Viewpoint papers are intended to provide an overview of emerging technologies and other issues facing the IT sector. A Viewpoint will not necessarily offer mitigation advice; other CPNI products do this.
This viewpoint provides a summary of hardware keyloggers along with protective advice covering physical, personnel and information security.
This viewpoint describes the architecture and security considerations of the Domain Name System (DNS).
This viewpoint outlines the key 802.11 wireless architectures in use by industry today and considers the security of each.
WiMAX is a standards-based technology enabling the delivery of 'last mile' broadband wireless access. This Viewpoint discusses the key features of WiMAX, security considerations and typical architectures.
Voice over IP (VoIP) is the term used for a set of technologies that enable real time voice or video conversations to take place across IP networks.This Viewpoint discusses the special case of Hosted VoIP, in which the corporate VoIP telephony system is hosted and managed by a third party network operator or service provider.
Enterprise VoIP, the subject of this Viewpoint, encompasses systems deployed by large organisations that would traditionally run internal telephony services.
This Viewpoint focuses on internet VoIP which involves peer-to-peer telephony via the public internet.
Web services are based on XML. If web services become widely adopted, XML will also be widely adopted. Is this a good thing overall for security? This paper attempts to answer that question, looking at the advantages and disadvantages of XML from a security perspective.
This Viewpoint provides advice on how to protect your organisation from DDoS attacks. It includes background information on how a DDoS attack works and methods of defence and response.
Protocol tunnelling is anything that allows a protocol to cross a network other than by explicit transmission. This Viewpoint looks at some general properties of tunnelled protocols, and discusses the associated risks. The paper also considers the steps that can be taken to mitigate these risks.
Virtual Private Networks (VPNs) are now widely recognised as a cost-effective method for protecting communications for organisations large and small. In this Viewpoint, we define what is meant by a VPN, and describe the main benefits and advantages, including some novel and less well-known applications. We list the technologies that implement VPNs and mention the main security issues and other obstacles to consider when deploying one.
A firewall separates two regions of an IT system, restricting the traffic that can pass between them. This Viewpoint describes the different types of firewall and provides a brief overview of the scope and limitations of a firewall.
Voice over IP (VoIP) is the name given to a set of technologies that enable real-time voice or video conversations to take place across IP networks. VoIP devices may interface with the Public Switched Telephone Network (PSTN). This NISCC Viewpoint gives an overview of
