Netquette
typically refers to emails and, less frequently, texting and Twitter.
But all online communication has a need for Netiquette. the following
article is the best I have seen.
As the pandemic keeps millions around the world at home, video conferencing is taking on a more important role in the workplace. (Zoom, for example, saw daily meeting participants jump from 10 million pre-pandemic, to a peak of over 300 million.) But a few months in, barking dogs and background spouses aren’t cute anymore, etiquette experts warn. Here are some simple rules they suggest to maintain your professional credibility:

remote access
|
|
Remote access is the
ability for an authorized person to access a computer or a network from a geographical
distance through a network connection.
Remote access enables users
to connect to the systems they need even though they are physically far away.
This is especially important for employees who work at branch offices, are
traveling or are
telecommuting to work.
Technical support professionals also use remote access to
connect to users' computers from remote locations to help them resolve issues
with their systems or software.One common method of providing remote access is through a virtual private network (VPN) connection. A VPN creates a safe and encrypted connection over a less secure network, such as the internet. Enterprises can also provide remote access by using remote desktops. Remote desktop software allows apps that run on a network server to be displayed locally on network clients at the same time. Continue reading... |

air
gapping

| Air
gapping is a security measure that involves physically isolating a
computer or network to prevent it from connecting directly or wirelessly to
other systems that can connect to the Internet. Air gapping is used to
protect many types of critical systems, including those that support the
stock market, the military, the government and industrial power industries.
To prevent unauthorized data extrusion
through electromagnetic or electronic exploits, there must be a specified
amount of space between the air-gapped system and outside walls and between
its wires and the wires for other technical equipment. In the United States,
the U.S. National Security Agency TEMPEST project provides best practices for
using air gaps as a security measure.
For a system with extremely sensitive data,
a Faraday cage can be used to prevent electromagnetic radiation (EMR) escaping
from the air-gapped equipment. Although such measures may seem extreme, van
Eck phreaking can be used to intercept data such as key strokes or screen
images from demodulated EMR waves, using special equipment from some distance
away. Other proof-of-concept (POC) attacks for air- gapped systems have shown
that electromagnetic emanations from infected sound cards on isolated
computers can be exploited and continuous wave irradiation can be used to
reflect and gather information from isolated screens, keyboards and other
computer components.
As of this writing, the Defense Advanced
Research Projects Agency (DARPA) is awarding grants for prototype hardware
and software designs that will keep sensitive data physically isolated. The
grants are made possible under the Guaranteed Architecture for Physical
Security (GAPS) program.
Enhancing air-gapped security
measures
The problem with physical separation as a
security technique is that, as complexity increases in some system or network
to be isolated, so does the likelihood that some unknown or unauthorized
external connection will arise.
Perhaps the most important way to protect a
computing device or network from an air gap attack is through end user
security awareness training. The infamous Stuxnet worm, which was designed to
attack air-gapped industrial control systems, is thought to have been
introduced by infected thumb drives found by employees or obtained as free
giveaways.
The software-defined
perimeter (SDP) framework is another tool network engineers can use to create
a type of "virtual air gapping" through policy enforcement. SDP
requires external endpoints that want to access internal infrastructure to
comply with authentication policies and ensures that only authenticated
systems can see internal IP addresses. |
