Understanding CybersecurityCybersecurity is the method of protecting programs, networks, and systems fromdigital attacks. Cybersecurity includes technologies, processes, and controls.Generally, cyberattacks are intended at damaging, modifying, or accessingsensitive information; disrupting normal business processes; or extracting moneyfrom users.Office of Personnel Management in the US was hacked in April 2015, resulting inthe theft of approximately 21.5 million personnel records. It is believed to beone of the most important historic violation.The data breach compromised on Personally Identifiable Information (PII) likeSocial Security Numbers, name, and address.Malicious programs or Malware are specifically designed to delete, block,modify, or disrupt the performance of computers and computer networks.Malwares include Viruses, Worms, Trojans, Spyware, Adware, Ransomware, andScareware. Out of these, Viruses and Worms are two of the most familiarmalicious programs.VirusVirus is a type of malicious software that can self-replicate and spread toother systems or hosts, eventually corrupting the systems.Requires an active operating system/active host program or an already-infectedsystem to run and cause damage.Virus spreads easily to other hosts through some means, one of the frequentmeans being email attachment.WormUnlike virus, worm is a standalone software that does not need human help/hostprogram to spread.Worms can advance and self-replicate within a system using up resources such asprocessing and memory.Enters the system through a vulnerability and attacks information-transportfeatures/file-transport of the system.SpywareSpyware is designed to extract data from its host computer for marketingpurposes. It then transmits that data to a remote system without the user'sknowledge.AdwareAdware is similar to spyware, but it has been designed for advertising. Such asin a pop-up screen.Adware and Spyware are commonly known as Potentially Unwanted Program - PUP.A potentially unwanted program (PUP) is a software that can be considered asnonessential, whose implementation can compromise privacy or weaken thecomputer's security.RansomwareRansomware holds a system captive and demands a ransom to regain access.Ransomware restricts access to the computer either by encrypting files on thehard drive or by displaying messages that are meant to force the user to pay themalware creator to eliminate the restrictions and retrieve access to theirsystem.ScarewareScareware tricks users by making them believe that their computer has beeninfected with a virus and then suggests to download and pay for fake antivirussoftware.

• Worms typically do not require human intervention to spread across networks.
• Robert Morris, a computer science student at Cornell University, unleashed the first worm into the Internet from the Massachusetts Institute of Technology on November 2, 1988.
• Viruses and worms are a type of malicious software.
• Worms frequently take advantage of network configuration mistakes or security flaws in the operating system (OS) or applications.
