What Is ACON?
It’s a command-line tool built to monitor and manage network connections, giving a no-fuss way to protect systems. What’s so great about it is how easy it is to use—you don’t need to be a cybersecurity guru to get the hang of it, which is perfect for folks who aren’t pros but still want to keep their networks secure.
The real magic of ACON is how it hands over the reins to control network traffic. Whether you’re trying to block a sketchy IP, lock down a port you’re not using, or just keep an eye on what’s going in and out, ACON has you covered. Running it on a home network showed just how strong and simple it is to work with, making it a top pick for anyone who wants to stay ahead of cyber threats.
The Growing Importance of Network Security
Network security has never been more critical. A few years ago, a coworker’s laptop was compromised due to an unsecured network. Hackers gained access, stole personal files, and locked the system with ransomware—a devastating experience. Stories like this highlight how real cyber threats are, and they’re not just targeting big corporations. Everyday users are at risk too, with attackers constantly searching for vulnerabilities to exploit.
Many attacks begin with something as simple as an open port or a connection to a malicious server. That’s where a security tool like ACON becomes invaluable. By allowing users to manage network traffic and block potential threats, ACON helps prevent issues before they escalate. Staying proactive is key, and ACON offers the tools needed to do just that.
How to Install ACON
Setting up ACON is a straightforward process, which is a big plus for anyone eager to get started. Here’s how to do it:
1. Clone the Repository: ACON is available through a repository. Open a terminal and type:
git clone https://github.com/IHA089/ACON.git

2. Navigate to the ACON Directory: After cloning, move into the ACON folder by typing:
cd ACON

3. Run the Install Script: A script simplifies the installation process. Just type:
chmod +x install
sudo ./install
Sudo might be required since ACON adjusts network settings, but the script takes care of everything else.

4. Begin Using ACON: Once installed, ACON can be accessed from anywhere in the terminal by typing acon. It’s ready to use!
A quick note: ACON works only in Linux systems, such as Ubuntu, kali linux, parrot os etc.
Exploring ACON’s Features: A Powerful Security Tool
ACON is packed with features that make managing network connections a breeze. After experimenting with it, the capabilities really shine through. Here’s a look at what this tool offers, based on the help menu accessible by typing acon -h
in the terminal.
1. Managing Incoming Connections with Ease
ACON provides several options for handling incoming connections, which is essential for keeping unwanted access at bay:
- To allow all incoming connections temporarily—perhaps while testing a new application—simply type
acon -a in
. This has proven helpful during troubleshooting. - Spot a suspicious IP trying to connect? Block it with
acon -b in 192.168.1.100
(replace with the actual IP). This came in handy when unusual activity appeared in network logs, and blocking the IP stopped it immediately. - Check blocked IPs using
acon -a viewin
to ensure everything is under control. - If an IP needs to be unblocked,
acon -a removein
does the trick quickly.
2. Controlling Outgoing Connections
Outgoing connections deserve just as much attention, and ACON makes it simple to manage them:
- Allow all outgoing connections with
acon -a out
. - Prevent the system from connecting to a specific IP using
acon -b out 203.0.113.5
. This was useful when an app tried reaching an untrusted server. - View blocked outgoing IPs with
acon -b viewout
. - Unblock an IP when necessary by typing
acon -a removeout
.
3. Securing Ports Effectively
Ports act as gateways to a system, and ACON offers tools to lock them down:
- Block a port with
acon -b 23
. For example, port 23 (Telnet) was blocked since it wasn’t in use, reducing potential vulnerabilities. - See which ports are blocked with
acon -q view
. - Unblock a port if needed using
acon -p remove
.
Real-World Examples of ACON in Action
ACON has proven its worth in several scenarios, showcasing its ability to secure networks effectively. Here are a few examples:
1. Blocking a Suspicious IP
While reviewing router logs, an IP—192.168.1.100—was found attempting to connect repeatedly. It seemed off, so the decision was made to block it. The command used was:
acon -b in 192.168.1.100
A quick check with acon -b viewin confirmed the IP was blocked, and the connection attempts ceased, providing peace of mind.

2. Securing an Unused Port
An article mentioned that port 23 (Telnet) is often targeted by attackers. Since Telnet wasn’t needed, blocking the port seemed like a smart move. The command was:
acon -b 23
Using acon -q view verified that port 23 was blocked, closing off a potential vulnerability.
3. Halting an Outgoing Connection
An application was found attempting to connect to an unrecognized server at 203.0.113.5. To be safe, the connection was blocked with:
acon -b out 203.0.113.5
A check with acon -b viewout confirmed the block, allowing further investigation into the app without concern.
Why ACON Stands Out as a Security Tool
After trying various network security tools, ACON has quickly become a favorite for several reasons:
- Lightweight Design: ACON doesn’t slow down systems, running efficiently in the background.
- Empowering Control: It allows precise management of what can connect to a system, offering a sense of authority over network traffic.
- User-Friendly: Despite being a command-line tool, ACON is approachable, thanks to its help menu and simple commands.
- Cost-Free: Being free makes ACON accessible to everyone, which is a huge plus for such an effective tool.
Why ACON Deserves a Spot in Your Security Toolkit
ACON has proven to be an invaluable asset for network security, offering a simple yet powerful way to protect systems. From blocking suspicious IPs to securing unused ports, it provides the tools needed to stay ahead of potential threats. Anyone looking for a reliable security tool should definitely give ACON a try—it’s a fantastic addition to any cybersecurity strategy.
