Firewall
A firewall is a security system that monitors and controls
incoming and outgoing network traffic. It acts as a barrier
between a trusted internal network and untrusted external
networks, like the Internet. By filtering traffic and preventing
unauthorised access to a system, a firewall helps to ensure
that malicious entities cannot enter your network and steal or
corrupt your data.
NETIQUETTES
Netiquette refers to the accepted social behaviours and guidelines for interacting with others on
the Internet. Just as in face-to-face communication, it is important to be respectful, polite, and
considerate when communicating online. This includes not posting offensive content, respecting
others' privacy, and avoiding harmful behaviours like cyber bullying and trolling.
Some basic netiquettes are:
Treat others online with respect, just like in person.
Don’t share personal information and introduce yourself before chatting.
Use correct spelling and grammar, and avoid all caps.
Respect privacy, credit original creators, and follow community rules.
Be open-minded, and report abusive behaviour to protect yourself and others.
CYBER LAW
Cyber law refers to the legal regulations and laws that govern activities on the Internet. It covers
a wide range of issues, including privacy, data protection, cybercrime, intellectual property, and
online contracts. With the rise of Internet usage, cyber laws are becoming increasingly important
for protecting both individuals and businesses from online threats.
In conclusion, the Internet is a powerful tool that connects people and devices across the world,
but it also comes with risks. Understanding the various types of networks, being aware of online
threats like malware and phishing, and using protective measures like firewalls, antivirus software,
and strong passwords can help ensure a safer online experience. Respecting others through
netiquette and understanding cyber laws are also key elements of responsible Internet use.
Cyber law: Indian IT Act 2000
The Indian IT Act 2000 (Information Technology Act, 2000) is the primary law governing cyber
activities in India. It was enacted to facilitate electronic commerce, ensure the legal recognition
of electronic transactions, and address cybercrimes. The Act covers a broad range of issues,
including the legal validity of electronic records, digital signatures, and electronic contracts,
helping to promote the growth of online businesses and secure transactions.
