5 Email Security Threats That Are a Cause For Concern

Katrina Thompson

In the wake of sophisticated and expensive network security measures, protecting the lowly email server often gets missed. However, attackers count on this and have made even greater inroads into an already lucrative route for malware. Verizon’s 2022 Data Breach Investigations Report notes that email is still one of the two top delivery methods for malicious payloads, and the median organization receives three out of four malware payloads in this way.

Why a Picture Is Worth a Thousand Files

Alyn Hockey

The world is a visual place. Communication with photos and short videos has now become commonplace thanks to applications like Instagram and TikTok. Photos are easily taken from accessible devices and used to share information such as events, news, and even emotions at a rate and speed unlike anything before. But what many may not realise is that photos can also be used to inconspicuously share data or carry out a cyber-attack.
The practice of concealing messages, images, or files within other messages, images, or files is called steganography. It comes from the Greek word steganos (covered) and the Latin word graphia (graphy). With the popularity of photos and images, this hacking method will likely increase and continue to see success.

Applying UX Design To Cybersecurity

Luke Smith

If there’s one thing businesses should always focus on, it’s user experience (UX).

Increasingly, cybersecurity is becoming a big part of the user’s experience. Keep reading to find out more about how the two intersect, and how you can apply UX design to cybersecurity.

Why Mid-Market Enterprises are Becoming Top Targets for Cyber Criminals (and What They Can Do to Prevent It)

Robert Sugrue

In the last few years, many large businesses have overhauled their approach to cyber security. The rise of remote working forced them to bring forward long-planned upgrades to both security technology and processes, resulting in far better data security across the board.
On paper it seems like very good news, but it isn’t necessarily for everyone. Why? Because the majority of cyber criminals are opportunists looking for the quickest and easiest way to make the maximum amount of money possible from victims. Consequently, they tend to target larger businesses that have more assets for exploitation. However, as these large businesses continue to shore up their cyber defences, cyber criminals have started looking elsewhere for easier targets, and many of them are turning their attention to lesser protected mid-market enterprises instead.

The Power of eBPF for Cloud Native Systems

David Soldani

By 2025, Gartner estimates that over 95% of new digital workloads will be deployed on cloud-native platforms, up from 30% in 2021. At the same time, Kubernetes is becoming the de facto standard for cross-cloud orchestration and a pillar of cloud native architectures.
A contributing technology that will play a big role in this transition is the extended version of the Berkeley Packet Filter (eBPF). eBPF enables programs to run in kernel of the host operating system (Linux, first, and now also Windows), and to instrument the kernel without changing kernel source code. eBPF programs are portable between kernel versions and atomically updateable, which avoids workload disruption and node reboot. eBPF programs can be verified at load time to prevent kernel crashing or other instabilities.
