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.
