ARP-poisoning on wireless network – no packets

Summary

+ ARP-poisoning on wireless network can be prevented by implementing proper security measures and monitoring tools to detect unauthorized access.
+ Steps to prevent ARP-poisoning on wireless networks include updating firmware, enabling WPA2 encryption, using a firewall, and disabling DHCP.

Introduction

+ ARP-poisoning is a type of cyber attack that can be carried out on a network to redirect traffic from one device to another. This attack is also known as DHCP starvation or DHCP spoofing and can lead to unauthorized access, data theft, and other malicious activities.
+ ARP-poisoning attacks are commonly used to intercept traffic on wireless networks, which are more vulnerable to such attacks due to their open nature and limited security measures.

– Prevention measures for ARP-poisoning on wireless networks
1. Update firmware
+ Keeping the firmware of the wireless network up-to-date can prevent vulnerabilities that can be exploited by attackers to carry out ARP-poisoning attacks.
2. Enable WPA2 encryption
+ Encryption is a critical measure to ensure that data transmitted over the wireless network is protected from unauthorized access. WPA2 encryption provides strong security and should be enabled on all devices connected to the network.
3. Use a firewall
+ A firewall can help prevent ARP-poisoning attacks by filtering traffic and blocking unauthorized access attempts. It is recommended to use both hardware and software firewalls for added protection.
4. Disable DHCP
+ DHCP can be used by attackers to carry out ARP-poisoning attacks, so it is recommended to disable it on the wireless network. Instead, assign static IP addresses to each device connected to the network.

– Monitoring tools for detecting ARP-poisoning attacks
+ Network administrators can use monitoring tools such as Wireshark and tcpdump to detect ARP-poisoning attacks and prevent them before they cause any damage.
+ These tools can capture network traffic and analyze it for signs of ARP-poisoning, such as unexpected changes in MAC addresses or IP addresses.

Conclusion

+ ARP-poisoning on wireless networks is a serious threat that can lead to unauthorized access and data theft. By implementing proper security measures and monitoring tools, network administrators can prevent these attacks and protect their networks from malicious activities.
