Regular System Updates and Patches: Tech At You can ensure that your systems are regularly updated and patched, helping to protect against any vulnerabilities that could be exploited by malicious actors.
Implementing Access Controls: Tech At You can help your business implement strict access controls, ensuring that only authorized individuals have access to sensitive data. This can help prevent data exfiltration by limiting who can access your data.
Regular Security Assessments: Tech At You can perform regular security assessments to identify any potential weaknesses in your security measures and recommend improvements.
Data Loss Prevention (DLP) Tools: Tech At You can implement DLP tools that can detect potential data breaches/transfers and prevent them by monitoring, detecting and blocking sensitive data while in-use, in-motion, and at-rest.
Employee Monitoring: Tech At You can provide solutions for monitoring employee activity to prevent insider threats. This includes monitoring for unusual data access or transfer activities.
Step 1: Access WHM and Navigate to Exim Configuration
Log in to WHM: Use your administrator credentials to log in to your WHM panel.
Navigate to Exim Configuration Editor: Once logged in, search for “Exim Configuration Editor” in the search box or find it under the “Service Configuration” section.
Step 2: Access the Exim Advanced Editor
In the Exim Configuration Editor:
Click on the “Advanced Editor” tab. This is where you can make detailed changes to your Exim configuration.
Step 3: Find the “Section: AUTH”
Using Browser’s Find Feature:
Once in the Advanced Editor, you can quickly navigate through the dense configuration by using your browser’s find feature. Press Ctrl + F on Windows or Cmd + F on Mac and type “Section: AUTH” to jump directly to the relevant section.
Step 4: Configure Authentication
Configure AUTH Section:
Under “Section: AUTH,” add the following details (ensure you replaced the “client_send” data with your own username and password or Secret Key/API info):
Navigate to the “Section: ROUTERSTART” and add the following configuration (Make sure to replace “smtp.example.com” in the route_list with your host.):
Proceed to “Section: TRANSPORTSTART” and input the detials below (ensure you replaced the “Port = , hosts = “ data with your own, leave port as is if you do not know).
Go to main WHM page > List Accounts > Click cPanel Logo to bring up account cPanel > Email Accounts > Create Email Account > Check Webmail > Compose and send a email to an outside email address e.g. gmail.com.

A UDP flood is a type of denial-of-service attack in which a large number of User Datagram Protocol (UDP) packets are sent to a targeted server with the aim of overwhelming that device’s ability to process and respond. The firewall protecting the targeted server can also become exhausted as a result of UDP flooding, resulting in a denial-of-service to legitimate traffic.
How does a UDP flood attack work?
A UDP flood leverages the procedural response of a server to incoming UDP packets at its ports. Ordinarily, upon receiving a UDP packet, the server undergoes a two-step verification process:
It first identifies whether there are any active programs poised to accept requests on the targeted port.
Should it find the port devoid of listening programs, the server issues an ICMP (ping) packet back to the originator, signaling the unreachability of the destination.
This process can be analogized to a hotel receptionist managing incoming calls. Upon receiving a call, the receptionist checks whether the requested guest is present and accepting calls. Discovering the guest’s unavailability, the receptionist must inform the caller of their inability to connect the call. The scenario becomes overwhelming when multiple calls flood in simultaneously, each requiring the receptionist to verify availability and respond accordingly—this is the crux of a UDP flood attack, aimed at inundating the server with futile packet checks and responses.
Whenever the server receives a new UDP packet, it processes the request, using server resources along the way. Each UDP packet sent includes the sender’s IP address. In a DDoS attack of this kind, attackers typically hide their actual IP address by falsifying (or “spoofing”) the source IP address in the UDP packets. This tactic prevents the attacker’s true location from being revealed and avoids the possibility of their location being overwhelmed by response packets from the server they’re targeting.
As the server expends resources to verify and respond to each UDP packet, its resources can be quickly depleted if a massive volume of UDP packets is sent its way. This can lead to a denial-of-service for legitimate traffic, as the server becomes overwhelmed.
