In our previous discussion on the importance of cybersecurity in remote working environments, we highlighted that 61% of organisations have yet to establish a Bring-Your-Own-Device (BYOD) security policy, even as devices such as tablets, smartphones, and personal laptops become common tools for professional tasks.
The Challenge of Unsecured Applications
When applications operate on your network, can you be confident in their activities? Cyber criminals are increasingly leveraging fileless malware to infiltrate built-in operating system tools—like PowerShell—without the knowledge of your end users. This stealthy strategy allows them to execute malicious scripts and manipulate your systems from the inside, potentially leading to significant data theft or disruption.
The Solution: Application Containment and Isolation
To combat these threats, it’s vital to contain and isolate your applications. This involves controlling how each application interacts with every file, software component, registry entry, and network resource.
We recommend using Ringfencing™, a solution offered exclusively by our partner, ThreatLocker. This tool allows you to supervise how your whitelisted applications function within your network. Once an application is approved, Ringfencing™ ensures it operates securely, barring any malicious scripts or codes from executing on your devices.
How Ringfencing™ Enhances Security
Ringfencing™ effectively prevents applications from interacting in ways that could introduce fileless malware, safeguarding your data from theft:
- Preventing Cross-Application Interference: By stopping applications from interacting with each other in unauthorised ways, Ringfencing™ eliminates the pathways through which fileless malware typically spreads.
- Blocking Malicious Scripts: If cyber criminals attempt to run harmful scripts within your applications, Ringfencing™ thwarts these efforts, ensuring that your applications perform only their intended functions without compromise.
The Outcome: Trust in Your Network’s Integrity
With Ringfencing™, you gain the assurance that your applications will operate exactly as expected, devoid of any malicious interference. This level of control is crucial for maintaining the integrity and security of your network, especially in a remote working context where traditional perimeter-based defences are less effective.
Embracing Ringfencing™ not only strengthens your cybersecurity posture but also aligns with best practices for remote working environments, helping to protect your critical assets from sophisticated cyber threats.
