You can tunnel through the floor. There is the service entrance, the employee entrance, and access on the roof. Criminals who want to rob a bank will probably use an open route – such as a side door. It’s easier than breaking down a wall. Criminals who want to break into your network face a similar challenge. They need to enter. They can look for a weakness in your -

Today, compromised systems, database thefts, and technology breaches remain common fixtures in news feeds around the world. As a natural response, the technology industry is rabidly focused on improving the security and encryption of communications across all platforms. Since those early days of enlightenment, industry experts have discussed and attempted a variety of new strategies to combat “pervasive monitoring” of email channels.

In early 2021, for example, the state received more than 153 million robocalls (about 57 per second) in the span of just one month. That ranked Illinois eighth in the country for these calls, according to the robocall-blocking fi rm YouMail. While there are helpful robocalls (alerting you to school closings or when a prescription is ready), YouMail estimates about 42 percent of the calls in Illinois were scams and another 22 percent were simply marketing pitches.

The History of Spam Timeline of Events and Notable Occurrences in the Advance of Spam
The History of Spam Timeline of events and notable occurrences in the advance of spam July 2014 The History of Spam The growth of unsolicited e-mail imposes increasing costs on networks and causes considerable aggravation on the part of e-mail recipients. The history of spam is one that is closely tied to the history and evolution of the Internet itself. 1971 RFC 733: Mail Specifications 1978 First email spam was sent out to users of ARPANET – it was an ad for a presentation by Digital Equipment Corporation (DEC) 1984 Domain Name System (DNS) introduced 1986 Eric Thomas develops first commercial mailing list program called LISTSERV 1988 First know email Chain letter sent 1988 “Spamming” starts as prank by participants in multi-user dungeon games by MUDers (Multi User Dungeon) to fill rivals accounts with unwanted electronic junk mail. 1990 ARPANET terminates 1993 First use of the term spam was for a post from USENET by Richard Depew to news.admin.policy, which was the result of a bug in a software program that caused 200 messages to go out to the news group. The term “spam” itself was thought to have come from the spam skit by Monty Python's Flying Circus. In the sketch, a restaurant serves all its food with lots of spam, and the waitress repeats the word several times in describing how much spam is in the items. When she does this, a group of Vikings in the corner start a song: "Spam, spam, spam, spam, spam, spam, spam, spam, lovely spam! Wonderful spam!" Until told to shut up. -
