Packet Sniffing Prevention

Question 1

Juniper Firewalls can support encryption protocols and Virtual Private Networks (VPNs) to secure data in transit. These technologies encrypt network traffic, making it unreadable to unauthorized packet sniffers.

Answer 1

Encryption and VPNs

Question 2

Juniper Firewalls can implement port security measures to restrict the number and type of devices that can connect to specific network ports. Unauthorized devices attempting to connect for sniffing purposes are blocked.

Answer 2

Port Security

Question 3

Some Juniper Firewalls offer content inspection capabilities. They can inspect network packets for malicious payloads and patterns associated with packet sniffing tools. If detected, the firewall can take action to block or alert on suspicious activity.

Answer 3

Content Inspection

Question 4

IDS/IPS capabilities in Juniper Firewalls can detect and alert on unusual or suspicious network activities, including the presence of packet sniffers. They can identify unauthorized sniffing attempts and trigger alerts for further investigation.

Answer 4

Intrusion Detection/Prevention System (IDS/IPS)

Question 5

Juniper Firewalls equipped with WIDS capabilities can monitor wireless networks for unauthorized sniffing devices. They can detect and mitigate the risks associated with packet sniffing over Wi-Fi.

Answer 5

Wireless Intrusion Detection System (WIDS)
