Viruses
A type of malware that is self-propagating program code that is triggered by a specific
time/event.
Worm
a software program capable of reproducing itself that can spread from one computer to
the next over a network. It does not erase data.
Trojan Programmes
Contains code intended to disrupt a computer, network or website. They do not replicate
themselves.
A logic bomb
Type of Trojan program used to release a virus, worm, or other destructive code
Backdoors
programming routine built into a system by its designer or programmer. It enables the
designer to bypass system and sneak in later.
Blended threat
A security threat that combines characteristics of viruses,worms and other malicious
codes with vulnerabilities found on public and private networks.
Denial-of-service attacks
Flooding server with thousands of false requests to crash the network
Social engineering
hackers use their social skills to trick people into revealing access credentials or other
valuable information
Cryptojacking
where hackers secretly use the computing power of a user in order to mine
cryptocurrency.
Biometric security measures
use a physiological element that is unique to a person and cannot be stolen, lost,
copied, or passed on to others
Nonbiometric security measures
callback modems, firewalls, and intrusion detection systems
Physical security measures
primarily control access to computers and networks, and they include devices for
securing computers from theft
Access controls
designed to protect systems from unauthorized access in order to preserve data
integrity
Virtual private networks
A secure connection through the internet for transmitting messages and data via a
private network
Data encryption
