As the IT industry has grown, many terms have been used to describe the methods used by hackers, governments, and others to destroy or steal data. Some systems are attacked almost continuously. While many of these thieves and saboteurs are technically brilliant, others simply take advantage of their victims’ poor security practices.
In light of the high threat level, anyone responsible for data security needs to be vigilant and proactive. A thorough IT Assessment Omaha NE could reveal security defects that should be fixed immediately.
The Classes of Malware
Often, terms such as “virus” are used to represent all malware or malicious software. A brief explanation of some of the terms will illustrate the varying methods used by businesses, governments, organizations and individuals.
Virus:
A virus inserts copies of itself into another program, rapidly spreading from one computer to another. The effects of a computer virus can range from annoying to damaged data to causing a denial-of-service (DoS). Viruses are usually attached to an executable file, such as an email attachment. When the user runs or opens the malicious host file, the virus activates.
Worms:
Worms replicate in a similar manner to viruses but differ in that they are standalone software. No host program or help from humans is needed. Worms exploit a known vulnerability on the target system to enter and spread.
Trojans:
A trojan is a malicious software that appears legitimate; it does not self-replicate, like viruses and worms, but depends on human action, such as running an internet file or opening an email attachment. The damage caused by a trojan can range from irritating to very serious, including stealing data, deleting files or spreading the virus or other malware. A trojan can also be used is to create a back door, allowing the trojan’s sender to have access to the system.
Bots:
A bot is an automated process, such as the web crawlers used by search engines, and can be used for good or evil. A malicious bot can create a “botnet” or network of compromised devices that is used to generate broad-based attacks on the target. Bots can be used in numerous ways to compromise a system.
Can Malware Damage the Physical Hardware?
No. Malware can only damage data and software.
