1. Firewall

   • A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.
     • A firewall typically establishes a barrier between a trusted internal network and untrusted outside network, such as the Internet.
     • Firewalls are often categorized as either network firewalls or host-based firewalls
     • Network firewalls filter traffic between two or more networks

2. Anti-virus

   • Antivirus or anti-virus software (often abbreviated as AV), sometimes known as anti-malware software, is computer software used to prevent, detect and remove malicious software.
     • Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats.
       • In particular, modern antivirus software can protect from: malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraudtools, adware and spyware
       • Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity (privacy), online banking attacks, social engineering techniques, advanced persistent threat (APT) and botnet DDoS attacks
         • DDos - Denial-of-service attack

3. Encryption

   • encryption is the process of encoding a message or information in such a way that only authorized parties can access it.
   • Encryption does not itself prevent interference, but denies the intelligible content to a would-be interceptor.
   • An encryption scheme, the intended information or message, referred to as plaintext, is encrypted using an encryption algorithm – a cipher – generating cipher text that can only be read if decrypted.

4. Password

   • A string of letters/numbers to secure a peice of information
     • MUST BE KEPT A SECERET
     • The terms passcode and passkey are sometimes used when the secret information is purely numeric, such as the personal identification number (PIN) commonly used for ATM acces
   • The use of passwords is known to be ancient.
