FIREWALL
A firewall can be hardware or software that controls network
traffic in a private network. It decides what traffic to allow or
block based on set rules. Each data packet is checked before
being allowed in or out.
Think of it as a gatekeeper letting trusted sources into your
network. Firewalls protect against harmful traffic but not
against malicious code. They don't provide complete security
on their own. Using antivirus software with a firewall enhances
protection against harmful code.
CYBER SECURITY
Cybersecurity is essential for protecting people, organisations, and governments from cyberattacks
and online crime. As technology evolves, it becomes increasingly important to safeguard digital
data. It ensures the privacy, accuracy, and availability of information. Cybersecurity is key to
protecting data in the digital world.
Some of the basic needs of Cybersecurity are:
Cybersecurity keeps personal and sensitive information private.
It shields us from malware, phishing, ransomware, and other threats.
Protects power, transport, healthcare, and finance systems for public safety and stability.
Helps organisations maintain customer confidence by securing digital operations and
transactions.
WHAT IS CYBERCRIME?
Cybercrime is defined as the crime committed using a computer and the Internet. It can be
committed against an individual or a group like the government, private companies, small or large
scale industries, organisations, etc. This may cause direct harm or indirect harm to someone’s
reputation, physical, social, or mental health.
There are majorly two categories of cybercrime:
Crimes that aim at hacking private networks of an organisation or devices and threatening
them with viruses, worms or Denial-of-Service (DoS).
Crimes that use computer networks to commit other criminal activities like Cyber stalking,
financial fraud, identity theft, etc.
Let us discuss about different types of cybercrimes.
Cyber Trolling
Cyber trolling is the act of deliberately upsetting people online by sparking arguments and
controversy. Trolls are found on platforms like X, Facebook, and Instagram, often targeting
popular figures or influencers. Anyone can troll, sometimes even those with good intentions.
