The internet itself is considered an unsecured network—a scary truth when we realize it’s essentially the backbone for how we give and receive information. That’s where internet security (or cyber security) comes in, and it’s a term that can get pretty broad, as well. This branch of security is technically a part of computer security that deals specifically with the way information is sent and received in browsers. It’s also related to network security and how networks interact with web-based applications.
To protect us against unwittingly sharing our private information all over the web, there are different standards and protocols for how information is sent over the internet. There are ways to block intrusions with firewalls, anti-malware, and anti-spyware—anything designed to monitor incoming internet traffic for unwanted traffic or malware like spyware, adware, or Trojans. If these measures don’t stop hackers from getting through, encryption can make it harder for them to do much with your data by encoding it in a way that only authorized users can decrypt, whether that data is in transit between computers, browsers, and websites, or at rest on servers and databases.
To create secure communication channels, internet security pros can implement TCP/IP protocols (with cryptography measures woven in), and encryption protocols like a Secure Sockets Layer (SSL), or a Transport Layer Security (TLS).
