Cybersecurity for remote workers
Taking the stress out of security
Security isn’t for the faint of heart. The volume and sophistication of attacks are intensifying relentlessly — and it’s clear that conventional defenses were not built for today’s mobile workers, branch offices, and ever-expanding perimeter. Relying on on antivirus products, firewalls, and closed systems that don’t share data or intelligence is a dead-end strategy. With less budget, fewer resources, and more employees working from home than ever, it’s time to look for new ways to enhance your digital security without spending excessively or overburdening your staff.

In this ebook we’ll look at the challenges facing today’s security professionals and explore some simple actions you can take to reduce malware, simplify security and secure a growing population of remote and roaming workers.
New defences for new threat
As the network changes, so does attack methodology. The speed and adaptability with which attackers spin up attack infrastructure creates new challenges for identifying and blocking malicious traffic for all businesses across all industries, including:
- Deceptive email spearphishing techniques that enable attackers to bypass conventional defenses and install ransomware and malicious code
- One-off malware packages that can’t be readily detected using signature-based solutions – regardless of how quickly those signature and profiles are updated
- Low and slow attacks that evade network-based defenses and allow attackers to infiltrate infrastructure and take data undetected over extended periods of time
- Malware kits and malware-as-a-service resources that increase threat volume by empowering bad actors and criminal organizations to engage in cyberattacks like malicious cryptomining, despite their lack of technical skills
DNS-layer security — secure employees working from home, easily
It’s time to use the internet to your security advantage. 91% of malware uses DNS to gain command and control, exfiltrate data, or redirect web traffic. But when internet requests are resolved by a recursive DNS service, they become the perfect place to check for and block malicious or inappropriate domains and IPs. Security teams that are not monitoring DNS for indications of compromise are missing an important opportunity.
DNS is one of the most valuable sources of data within an organization. It should be mined regularly and cross-referenced against threat intelligence to help security teams gain better accuracy and detection of compromised systems and improve visibility and network protection. IT security leaders should make proactive DNS-layer security a core component of their security strategies. It’s a great first line of defence against threats for employees working from home.
A better way to stop threats, faster
Increase visibility, decrease risk (and work!)
Most companies leave their DNS resolution up to their ISP. But as more organizations adopt direct internet connections and users bypass the VPN, this leads to a DNS blind spot. DNS requests precede the IP connection, which enables DNS resolvers to log requested domains regardless of the connection’s protocol or port. Monitoring DNS requests (as well as subsequent IP connections) is an easy way to provide better accuracy and detection of compromised systems, which improves security visibility and network protection.
The bottom line: IT security leaders are looking for more effective security strategies that don’t add complexity to their security operations.
