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.

When Should You Choose Online Backup Over Offline Backup?

When Should You Choose Online Backup Over Offline Backup

Data backups are among the top cyber security countermeasures against ransomware, flood, fire, and other threats to data availability. As long as you have backup copies of your data, your business will have a pretty good chance of recovering from almost any major disaster. But what kind of data backup solution is the best?

It depends on your specific requirements. These days, backup solutions can be grouped into two - online backups and offline backups. Each has its own advantages and disadvantages. Knowing when to select one over the other can help you maximise your financial resources when spending on a backup solution.

Since a comprehensive comparison of these two sets of solutions can be quite long, we’ve decided to focus first on online backups. In this post, we’ll help identify situations when an online backup would be a better fit. But before we do that, let me make sure our definitions of these terms are the same.

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.

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.

5 Hidden IT Risks that are Slowly Threatening your Business

5 Hidden IT Risks that are Slowly Threatening your Business

Information technology risks range from the very apparent to the silent and hidden. The majority of businesses mitigate the most obvious risks: only an irresponsible IT operation will do without network firewalls in place or skip on regularly updating operating systems and software.
