5 Ways to Protect Your IoT Devices

5 Ways to Protect Your IoT Devices

The internet of things (IoT) is undoubtedly growing rapidly. According to Gartner the typical CIO will be looking after triple the number of IoT devices in 2023, compared to the number of IoT devices under their security remit in 2018.

This influx is caused by a mix of repurposed consumer devices, IoT devices that support infrastructure and business-specific IoT devices. Dodging the explosion of IoT devices is impossible, and yes, IoT does deliver a lot of advantages – but the security implications can be serious.

What Goes on In the Dark Web?

Dark Web

The World Wide Web has always been a valuable source of information and a reliable means of communication to masses of users across the globe. With more than 5 billion Google searches made every day and a projected $3.5 trillion online retail sales for 2019, you’d think that the internet as we know it is already as vast as it can be.

Unknown to most people, however, is that the surface or visible web—the part of the internet which the average user can access through search engines—comprises only about 4% of the entire web. The rest is composed of the deep web, a small part of which is the oh-so-mysterious (for the curious) but essentially shady, dark web.

8 Ways to Secure Your Employees’ Mobile Devices

8 Ways to Secure Your Employees Mobile Devices

In this blog, we’ve covered many of the ins and outs of BYOD (bring your own device), including the pros and cons. In reality, much of the discussion is no longer about whether employees should be allowed to connect to company networks with their own devices, BYOD is simply becoming the standard way of operating.

A study published in 2016 suggested that 59% of businesses allow BYOD, and things have certainly moved along in the intervening years. The only remaining point of discussion is BYOD cybersecurity. In this post, we give you eight top tips to help ensure BYOD does not pose a threat to your business.

Beware the Growing Cryptocurrency Mining Malware Threat

Beware the Growing Cryptocurrency Mining Malware Threat

A new IT security threat is infecting computers across the globe, and it could be wreaking havoc on your organisation’s devices as you read this post. This malware threat uses a computer’s processing power to mine cryptocurrency, without the knowledge or consent of the owner.

Unauthorised cryptocurrency mining–or cryptojacking, as it is commonly called, is spreading like wildfire. This is not surprising, given how simple it is for cryptojacking scripts to infiltrate a computer. Hackers can initiate it using one of two methods:

Is Ransomware Still a Threat?

Is ransomware still a threat

The year 2017 was a dismal year for IT security, particularly in the arena of ransomware.

Less than 12 months ago, the ransomware worm WannaCry wreaked havoc across the globe, placing large organisations – including NHS trusts in England and Scotland, at the forefront of one of the most prolific cyber attacks in history. Then followed NotPetya (initially believed to be the Petya malware of 2016) in June, which also spread quickly and, even without the aid of human intervention, managed to harm multinational companies.

Yet more ransomware attacks compromised the data of individuals and organisations, but they were not nearly as high profile as the aforementioned attacks, and this prompted many people to believe that ransomware is no longer the threat that it was twelve months ago. But is this really the case?

4 Tips to Make Your Cloud More Resilient to A DDoS Attack

 4 Tips to Make Your Cloud More Resilient to A DDoS Attack

DDoS attacks are typically designed to inundate servers and entire networks by consuming computing resources through large volumes of traffic, connections, or requests. And so, because cloud infrastructures are assumed to be backed by a large assemblage of such resources, many people believe their servers are less susceptible to these types of attacks if they’re hosted in the cloud. But that’s not entirely true.

If your servers are hosted in a multitenant environment along with a bunch of other servers belonging to other organisations (which is usually the case in a public cloud), your servers could be at risk of collateral damage. If those other servers (note: not yours) are bombarded by a DDoS attack and your cloud service provider (CSP) attempts to absorb the attack, your own servers, which share the same underlying infrastructure with those other servers, could also suffer.

Help! I’ve been hacked: 5 next immediate actions

Data centre optimisation and consequential benefits for businesses

With so much focus on hacking and internet security, many firms of 10 - 100 people will feel that they have put a lot of effort into making their data as secure as possible. Unfortunately, internet security is a moving target, where the threat may be characterised as agile and continually evolving. Consequently, it is impossible for networks to remain impenetrable.

Standard IT best practice, such as upgrading and patching operating systems and applications, and maintaining a reliable backup and Disaster Recovery capability, are all layers that help to ensure that a firm is in a position to resume normal operations within an acceptable timeframe, should it be the victim of an attack.
