Packet sniffing as a legal activity is usually defined by the corporate or company policy. Most institutions will ban the activity unless your job role requires it. Outside of a company network there is usually no restriction on packet capturing/sniffing.
Packet sniffing is also done by certain types of programs, such as IDS or IPS devices/systems.
Do the right thing because its right.
In a LAN, the use of a networking switch can minimize problems with packet sniffing by implementing IPsec at layer 3which encrypts transmissions across the network link. (These damn ITT tech questions can be a pain sometimes, eh?)
Packet sniffing is usually sniffs wireless transmissions. Sniffing is the interception of data or packets. The person who is suppose to receive the information still does but a third party has the ability to eavesdrop read the data. Packets can range from harmless info like your latest homework assignment or other more sensitive information like your Bank statement. The method to avoid a person sniffing your data sent wirelessly is to encrypt the data with modern day encryption algorithms.
Ethics and legality are two different things. If it is not forbidden by law or the Ba Association's Canon of Ethics they can speak to whomever they wish.
Passive wiretapping, usually on a local area network, to gain knowledge of passwords. Attempt by an unauthorized entity to gain access to a system by posing as an authorized user is spoofing
If you think the NSA is not fully capable of sniffing every single internet packet for interesting words like "drugs", then you're delusional.
For a message to send out, it has to address which Mac address to send. If the message I received doesn't not match with my MAC address then my network interface will drop the packet completely. If your network is on promiscuous mode, then your network interface will not drop the message. It is good for packet sniffing. I hope this helps.
no sniffing tissue is harmless
no but sniffing gasoline is harmful to your health.
Legality Movement was created in 1941.
It is possible to "sniff" packets off any network - this could potentially allow a hacker to read communications over the network. Generally, using a secure connection (HTTPS) will prevent packet-sniffing, however.
