Initially, we create a new ModSecurity custom rules file: nano /etc/modsecurity/modsecurity_custom_nf Let’s now check on how our Support Engineers write the custom ModSecurity Rules for our customers to mitigate the attack. Till now we saw how we find more details about the attack. Thus if the website has only visitors from a specific region, it’s worth limiting access to a smaller region.ĭifferent ways to Block Country using ModSecurity Rule As a result, the country based block may not be effective in all scenarios. Moreover, advanced hackers can easily spoof or mask the location of the IP address. That is where the blocking of IP addresses based on country works. However, some amateur attackers use cherry-picked methods to launch attacks from specific regions of the planet. In the majority of the attacks, the access will be from a wide range of IP addresses.
Find the IP location detailsįurthermore, we make use of scripts based on ipAPI service that will help us to find IP location and organization. The below netstat result is a proper indication of the attack on the server.ĥ124 ESTABLISHED 3. Our Security Engineers check the IP address having a maximum number of connections to port 80 or 443. The very next step is to check the stat of the IP address connection. Here, the HTTP server had 56 connections from the IP 74.xx.169.xx.Ģ. Here, netstat command comes to the rescue.Ī sample set of results when the server is under attack appear as: 56 74.xx.169.xx We begin by checking the count of the IP address which is having a concurrent connection to the webserver. Grab details of IP address connections on port 80 Let’s now see how our Security Engineers isolate cases of attack from a particular country.ġ. When your website is under attack, the first step is to identify whether it is a country-based attack or not. Additionally, i t protects against web attacks and enables HTTP traffic monitoring. ModSecurity is a web-based firewall (or WAF) application supported by popular Web servers like Apache, Nginx, LiteSpeed, etc.įrom our experience in managing servers, we see that ModSecurity installed servers easily defends 80% of web application-level attacks. So, let’s discuss different ways that our Support Engineers use to Block Country using the ModSecurity Rules.Īs the first step, let’s check some information on ModSecurity as such. The ModSecurity application firewall uses s pecial security rules to prevent unauthorized website access.Īt Bobcares, we often receive requests to block the country/domain with the ModSecurity rule as a part of our Server Management Services. One of the best methods to prevent such attacks is to block a country using ModSecurity Rule. Is your web server facing a recent country-based attack?
