Encryption and Certificate Management

What is Encryption and Certificate Management? Encryption and Certificate Management is broadly about keeping secrets, secret. This is the say that many cryptographic systems exist to maintain the integrity of your information systems, more specifically from external actors who might do it harm.

The Conversation, on how we treat AI as a human

Evolution is making us treat AI like a human, and we need to kick the habit shutterstock. Neil Saunders, University of Greenwich The artificial intelligence (AI) pioneer Geoffrey Hinton recently resigned from Google, warning of the dangers of the technology “becoming more intelligent than us”. His fear is that AI will one day succeed in “manipulating people to do what it wants”. There are reasons we should be concerned about AI. But we frequently treat or talk about AIs as if

Automating Software Updates

Automating Software Updates – the why Automating Software updates is incredibly important, you may wonder why but the simplest way to express this is a figure from Gartner: the believe that 99% of security breaches are as a result of KNOWN vulnerabilities. This in turn means that 99% of your risk is already established and can typically be mitigated through a workaround or permanently. Patching, sometimes referred to as Patch Management, is ultimately about maintaining what you already have and is a critical

The Cost of Cloud Security

The Cost of Cloud Security There are a variety of reasons why investing in the security of your business is critical to you staying in-business, but many firms often believe they have certain capabilities such as backups or advanced antivirus when they in fact lack any of these capabilities. For a definition of ‘the Cloud’ please see here. One common example is when organisations move to Microsoft’s Office 365 platform or Google’s GSuite in the belief that this offers greater

IT Security in Conflict Zones

IT Security in Conflict Zones is complex When numerous small organisations or large private organisations face cyber-attacks from state-backed criminal hacking-groups a lot of harm can be done.

Ransomware and Phishing attacks can be done in high volumes and at scale, targeting particular industries or types of businesses. Key-stakeholders within a business are often

To protect your security, ask yourself these five questions Dragana Gordic/Shutterstock Iain Nash, Queen Mary University of London Houses are getting smarter: smart thermostats manage our heating, while smart fridges can monitor our food consumption and help us order groceries. Some houses even have smart doorbells that tell us who is on our doorstep. And of course, smart TVs allow us to stream the content we want to watch, when we want to watch it. If

Securing Mobile Devices

Securing Mobile Devices Mobile Devices can be Smartphones, OEM Tablets, standard Tablets and even Laptops depending on your definition. Some laptops now use the same ARM-chips which Smartphones use, resulting in them being treated as a Mobile Device by IT systems. You may wonder why organisations need to secure a Smartphone, but the real question is whether it is connected to your business IT systems – even if only email. In the event the answer is yes, then it is
