An endpoint is a remote computing device that communicates back and forth with a network to which is it connected. Examples of endpoints include:
- Desktops
- Laptops
- Smartphones
- Tablets
- Servers
- Workstations
With the advance of technologies like mobile, IoT, virtual and cloud, organizations are relying more and more on different types of endpoints. Each one is a possible opening that bad actors can use for breaching a system. Depending on the complexity of the environment, it can be difficult to identify all of them much less protect them.
Since each endpoint is unique and subject to different types of attacks, it is important to deploy a layered security approach to make it as difficult as possible for the bad guys to break in. Much like a home security system that uses alarms, cameras, deadbolt locks and barred windows, a layered cyber security approach uses various defenses throughout the enterprise that all work together to discourage someone from expending the effort to break into a system.
The first cybersecurity layer is composed of firewalls, web filters, and an antivirus solution. Firewalls monitor and control incoming and outgoing network traffic based on predetermined security rules. Web filters control access to inappropriate web sites that could be delivery vectors for malware. An antivirus solution prevents, detects and removes malware once it’s exposed to the system.
Keeping hardware, operating systems and software patched is the second layer. A software patch is a set of changes to a computer program that is designed to update, fix or improve it. Patching also includes fixing security vulnerabilities and other bugs to improve performance and usability.
The third layer is an endpoint security solution that expands and strengthens the defense by providing a platform to centrally manage a layered defense. An endpoint security solution delivers continuous monitoring, early detection, and the ability to roll out software updates and new security rules efficiently.
As long as there is a world-wide ‘black industry’ of cyber criminals dedicating untold effort and capital into ‘breach research’ our systems are not safe. This is why endpoint security is critical to a layered security strategy.
