The secret to having a well-rounded cyber defence strategy

Every IT admin has succumbed to at least one sleepless night from worrying about data security and fearing the outcome of a security breach. Overthinking is second nature to humans, but there would be one less problem to worry about if we found a permanent fix for cyberattacks.

But is there a cyber defence strategy out there that’s completely foolproof? One that keeps all cyberattacks at bay? No, a perfect strategy does not currently exist, but that doesn’t have to stop us from striving for a well-rounded one. Understanding the nature of attacks and employing different security solutions to cover all bases will help us approach the ideal security strategy.

So, where do we start? Well, if you’re not using many – or any – security solutions, you should opt for a combination of network security solutions and endpoint management solutions. This combination will provide robust protection against most known cyberattack variants.

Let’s break down these solutions’ components to get a better understanding of how they keep cyberattacks at bay:

1. Firewall: Setting up a firewall for your organisation forms the first line of defence against malicious network connections. A firewall controls incoming and outgoing traffic, and protects your network based on a defined set of security rules. You can adjust your security rules to allow outgoing traffic from particular applications while preventing incoming traffic for certain applications. Combine a firewall with an intrusion prevention system that selectively prevents threats or controls applications based on the type of firewall.

2. Proxy: Configuring a proxy server forms the next line of defence in cybersecurity. Whereas a firewall detects and blocks certain network traffic, a proxy server acts as a gateway between your network and the internet. Configuring your proxy to block known malicious websites helps protect your network from malware, phishing, and other cyberattacks.

3. Inventory: Taking inventory of all the devices that are present in your organisation helps you identify devices that shouldn’t be present. You should also identify the applications and software that these devices use.

4. Application control: Blacklisting unwanted or possibly malicious applications reduces the opportunities for data to be lost or stolen.

5. Patches: Consistently patching the software used in your infrastructure is crucial for eliminating potential attacks that occur through vulnerabilities present in outdated versions of software.

6. Antivirus: Using antivirus software stops known malware from being installed on your endpoints. Antivirus software also typically scans downloads for malware and blocks malicious executable files from being downloaded.

These six levels of protection serve as a wall of defence against malware and cyberattacks. While these methods will defend against known cyberattack variants, you need to ensure that you’re defending against new and evolving malware variants as well.

With the complexity of cyberattacks steadily increasing, the most common attack vector into an organisation is shifting towards browsers and since browsers are an integral part of today’s mobility-first, cloud-based world, this trend will only continue to increase.

Unfortunately, many organisations haven’t caught wind of this new element of IT security. What’s more, traditional endpoint management solutions don’t extend their protection to browsers.

So, here’s the final step to realising your ideal security strategy: implement a dedicated solution that scans for and secures all the loopholes present in your browsers, monitors and controls the add-ons used by your browsers, and controls the traffic accessed through your browsers. With a browser security solution, you’ll round out your security strategy, ensuring that you have fortified your enterprise’s defences against cyberattacks.
