This Is What Happens When You Don’t Take DNS Security Seriously

This Is What Happens When You Don’t Take DNS Security Seriously

When businesses embark on cyber security initiatives, one of the things that’s often overlooked is DNS security. Many people forget or simply aren’t aware that a compromised DNS infrastructure (or any critical component of that infrastructure) could potentially lead to considerable downtimes, malware outbreaks, data breaches, and several other forms of cyber incidents.

These things can happen because DNS or the Domain Name System plays a crucial role in almost any user-initiated activity that takes place on the Internet. DNS is in charge of resolving the easily-recognisable names like www.somesite.com or ftp.companyx.com that users enter into their web browsers, email clients, or file transfer clients into the IP addresses (e.g. 200.100.10.10) that computers use to communicate with one another.

Protecting Your Staff and Business from E-Mail Spoofing

Protecting Your Staff and Business from E-Mail Spoofing

The prevalence of firewalls and anti-virus software has closed many of the common attack vectors that cyber criminals use to gain unauthorised access to networks and to bypass online security. For this reason, attacks increasingly rely on fooling users into allowing access to systems: legitimate-looking emails that easily clear the common-sense hurdle can hide malware and well-planned hacking attacks.

Even with the necessary protections in place it is surprisingly easy to “spoof” an address, with a from field that looks correct in every way; except for the fact that the sender is not who it appears to be. Most users will think twice about opening an attachment sent by an unknown sender, but if the attachment appears to be from a colleague the usual caution is sometimes left by the wayside.

This Is How A Drive By Download Sneaks Malware Into Your System

This Is How A Drive By Download Sneaks Malware Into Your System

There used to be a time when it was relatively easier to prevent malware from infecting our systems. We’d install an antivirus, keep its database updated, and equip end users with a laundry list of things to avoid - like suspicious email attachments and unfamiliar websites. Today, drive by downloads are making malware avoidance a more challenging task.

A drive-by download is a malware infection procedure that doesn’t require the user to download anything or even click a link. For his/her system to get infected, the user only has to visit a site that’s been compromised. The infection process then takes place behind the scenes, without the user ever noticing anything unusual.

Britain Shaping Up to Confront Cyber Risks

Britain shaping up to confront cyber risks

In the wake of Brexit, it seems like there has never been a more important time to attract businesses to the UK. There are still plenty of reasons for multinationals to set up shop here. While it has experienced setbacks in recent times, London has retained its status as one of the world's financial hubs. We also have the fifth largest economy in the world according to GDP (Nominal), and despite the current uncertainty, there are still solid strategic reasons for companies basing themselves in the UK.

Yet it is the less obvious risks which can trip up even carefully run IT functions – and which can cause progressive or indeed sudden harm to your business.

Can Your Network Withstand The Onslaught Of IoT Botnets?

DDoS attacks that force websites to go offline and cripple servers are nothing new, but many of the massive DDoS attacks last year, which also happened to be the biggest in history, had a common characteristic we’ve never seen before. They all originated from hordes of zombified IoT devices, also known as IoT botnets.
