Firewall vendors revisit core technologies to win market. Firewalls should still be an integral part of any enterprise's cyber security strategy, and vendors of the hardware variety are redoubling their R&D to win more market share.

Firewall vendors revisit core technologies to win market

Firewall hardware is now evolving in line with two trends: one towards greater distribution of security across the enterprise with incorporation of intrusion protection, and the other tied to the growth of server virtualisation. This is blurring the traditional line between firewall hardware and software; and yet at the same time preserving some distinct niches for each. Firewalls are the network security systems that control incoming and outgoing data traffic by analysing the packets and determining whether they should be let 'through' or blocked, based on rules set by IT security policies, for instance. Quantum cryptography: using photons to create secure keys. It is essential that cryptography remains well ahead of the hackers, and that's precisely the motivation for a project that uses the quantum mechanical properties of photons to create tamper-proof keys.

Quantum cryptography: using photons to create secure keys

The future for the protection of sensitive data could be bright. Researchers have uncovered evidence that the quantum mechanical properties of photons (light particles) may be used to generate tamper-proof keys, and this represents a big leap forward in the fight against computer hackers and other cyber-security threats. Four and a half years ago, the EU-funded Secure Communication based on Quantum Cryptography (SECOQC) consortium successfully demonstrated long-distance, practical quantum-key distribution (QKD) in a fibre-optic network around the Austrian capital Vienna.

Battelle says that it is already in talks with organisations interested in using the technology. Mailvelope. GPGTools - It's worth protecting what you love. Gpg4win - Secure email and file encryption with GnuPG for Windows. Hacking the Internet - bringing down infrastructure.

Why should hackers try to disable computers when they might be able to set their sights higher?

Hacking the Internet - bringing down infrastructure

Routers can be just as vulnerable as servers, so why not bring down the entire Internet? The US Department for Homeland Security (DHS) was set up in November 2002 with the primary responsibility of protecting the USA and its territories from terrorist attacks, accidents, and natural disasters. However, its remit has slowly spread in recent years to cover the nation's Critical National Infrastructure, which includes the structure of the Internet itself. Surprisingly perhaps, the DHS has never really got to grips with raising the security of the Internet's own architecture – the integral global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve several billion users worldwide.

VoIP: voicing security concerns. Channelling voice calls over IP networks has brought many advantages to enterprise communications, but it also creates some security risks.

VoIP: voicing security concerns

Though Voice over Internet Protocol (VoIP) services are available for both consumer and business markets, it is from the latter that most enthusiasm for it has come; for this reason, it is also where most of VoIP's security issues occur. While the commercial sector has, of course, invested heavily in protecting their data networks from other cyber threats, IP-based voice has been somewhat overlooked. Online Visual Traceroute.

Infrastructure cyber attack threat grows. Despite high-profile attacks, there is still a lack of IT security in key public infrastructure.

Infrastructure cyber attack threat grows

We ask if it will take a major meltdown to prompt governments to take action. It is almost a year now since the attack on the control system of an Iranian nuclear reactor by the Stuxnet virus. However, despite this ominous development and recent reports that the threat of attacks has increased, a worrying amount of vital public infrastructure is still vulnerable. National Cyber Security Alliance. ID access management's cloud challenge. With users accessing systems from ever more obscure points of entry, how do you keep control of access privileges?

ID access management's cloud challenge

We look at the software that may have the answer. The problem of offsetting data security against accessibility has proved a ubiquitous problem of the last decade. As the range of software that users have to work with has broadened and security's remit has become enlarged, IT administrators have struggled to keep control of system and application access without complicating the login process. Identity access management (IAM) software has emerged as an important tool for administrators trying to regain control. Research firm Gartner has estimated that companies are spending roughly 8 per cent of their data security budget on IAM tools.

Cyber security - small firms now in the firing line

Media Reports about IT security breaches resulting in data loss and other compromises to corporate data integrity usually only make headline news when big name brands are hit. Resultant concerns about reputational damage have spurred many medium-to-large enterprises (MLEs) into reviewing their cyber-security strategies and redoubling their efforts to ensure that their ICT is properly protected - or at least as protected as possible within the context of their risk assessments and IT budgets. Because of their size a lot of the damage can over time be 'managed'. Disproportionate riches. Introduction to Cyber Security: More free resources from The Open University. Troy Hunt.
