Web server security: infrastructure components

introduction

Cybercriminals understand that your website is not only the face of your organization, but often its weakest link as well. With a single misconfigured port, a malicious spearphishing email, or an unpatched vulnerability, an attacker can deploy a range of techniques and tools to enter and then roam undetected across a network to find a valuable target. Once found, data can be exfiltrated, modified, deleted, or all of the above, depending on their motive, while still merging in their movement with legitimate network traffic.

All of this is enabled through web servers, making these devices not only vital for communication but also for the security of your organization. However, since web servers by their very nature are located near the edge of your network, they are designed to be accessed and pinged, at least sharing basic information about your organization with anyone in the outside world. .

Continuing the Infosec Skills series on web server protection, this article focuses on infrastructure components that can be deployed to keep attackers at bay, monitor malicious activity, log session activity, or even shut down cybercriminals. in their footsteps. While our review is by no means exhaustive, we’ll take a look at some of the most commonly used tools that help harden web servers.

The infrastructure components of web server protection

Firewall

A firewall is a device configured to protect and isolate an organization’s internal network from external traffic, allowing only specific connections to go through well-monitored ports and predefined rules. Firewalls can be implemented in software or hardware and can control the flow of inbound and outbound traffic based on specified criteria, such as IP addresses, time ranges, or the type or destination of a request. network.

In a sense, a firewall is often seen as an organization’s first line of cyber defenses. (Read more…)
