Privacy and the Internet of Things

It is almost impossible to attend any event that has an IT edge without hearing about the Internet of Things. Until recently, we only really used the Internet as a way of connecting people via computers and servicer. But we are hurtling forward into a world where all sorts of devices have sensors and controls that can be connected, controlled and read over the Internet. That's the Internet of Things.

Security is “a massively complex topic” - CA World

Security is “a massively complex topic,” according to Mike Gregoire, CEO of CA Technologies, who cited considerations including transparency (telling people how you will use the data you collect), protection (sadly, the bad guys seem to be smarter than the good guys, so organisations need to work together and share information about compromises) and identity (so data can be protected without frustrating bona fide users).

Self-encrypting drives

As data becomes ever more mobile there's an increased risk that it can fall into the wrong hands. And, while there are many technologies to try and prevent this from happening, or tracking a device down if it's lost or stolen, the ultimate solution to data security is preventing it leaving the storage device in the first place.

Cisco impresses with first crack at next-gen firewall

When we tested next-generation firewalls last May, at least one important security vendor wasn't there: Cisco, because they weren't ready to be tested. Now that the ASA CX next-generation firewall has had a year to mature, we put the product through its paces, using the same methodology as our last NGFW test.

Review: WatchGuard XTM2050

What is big, flexible, red and costs more than your average mid-range family sedan? Not a HSV—not quite that much—but this top of the range unified threat management (UTM) device (or in this case, XTM– the X presumably being a variable) is definitely in a high performance category. The XTM2050 from WatchGuard is one of a new breed of security devices that packs punch.

The encryption quiz

The complexity of encryption schemes has been increased dramatically in an attempt to outpace the development of computational tools designed to crack them. Now it's important to devise algorithms that can't be brute forced for trillions of years in the hopes that they will remain secure long enough to be useful before they, too, are broken. Here's a quiz about encryption to see how well you are versed in one of security's most important components. Keep track of your score and check at the end to see how well you stack up.

2011's biggest security snafus

Perhaps it was an omen of what was to come when the city of San Francisco on New Year's Eve 2010 couldn't get a backup system running in its Emergency Operations Center because no one knew the password.

Security breach

No company wants to be associated with a data breach, but if your systems are compromised the fallout can sometimes be more damaging than the act itself.

Penetration Testing

This is a real issue, and not just one for the well publicised attacks on major corporations such as Sony, Lockheed, Google, and Citi. It affects every business and organisation, large and small. More worrying still, it is now widely suggested that hackers and espionage organisations are moving away from directly attacking their target company, choosing instead to route their attack through suppliers to their target. Thus, even small and seemingly innocuous “third party” businesses who would not consider themselves as potential targets are now on the front line of this cyber war.

How Can Organisations Deal Intelligently with Information Security Breaches?

Data breaches are happening more frequently, compromising larger volumes of data than ever before. We seem to hear about new data breaches every day. The number of compromised records grows, while organisations are subjected to larger financial penalties, stronger legislative and regulatory scrutiny, and tangible reputational damage. For organisations that suffer a breach, responding in an intelligent and confident manner is critical.

Smart Cities deliver Innovation & Security

Smart city projects are among the most exciting technological initiatives around today and will play a major role in the world’s future growth and security. Modern technology lets us track and monitor many elements in a major urban environment – noise, light, traffic, weather, accidents and incidents, and use this data to improve people’s living and working conditions.

Incident Response Plan

Do you take a fatalistic approach to cyber attack? ‘Whatever will be, will be’ is an attitude in life (and movies) that is well suited to events that evoke a spontaneous response—like who will you marry? These are the questions posed in Doris Day’s song from the Hitchcock movie ‘The Man Who Knew Too Much’. They’re not appropriate for incidents which inspire fear, which Doris learns when her son is kidnapped.

The cost of a security breach; it’s not just about the purse strings

Security breaches are rarely out of the news and with these reports come the significant costs resulting from each attack. However, the immediate thought is often associated with a dollar amount; for example how much money are we forfeiting through lost sales? Consequently, many think that private enterprises are the only ones that are prone to be at risk of attacks on their networks. The fact is public sector, educational institutions and non-profit organisations are just as much at risk and the potential costs are both great and varied.
