Fill in the blanks:In the context of cyber security, social engineering (SE) is a deceptive practice that exploits human _______

lord [1]

Answer:

In the context of cyber security, social engineering (SE) is a deceptive practice that exploits human weaknesses by inducing victims to interact with a digital device in a way that is not in their best interest. Many of these attacks begin with spam , which is defined as unsolicited messages that are usually sent in massive numbers using electronic mail systems. A spam filter uses a set of rules to examine email messages and determine which are spam. There are four common types of spam filters. Content filters examine the content within a message for certain words or phrases commonly used in spam emails. Header filters review the email header for falsified information, such as spoofed IP addresses. Blacklist filters block mail that originates from IP addresses of known spammers. Permission  filters block or allow mail based on the sender's address. Phishing is an email scam that masquerades as a message from a(n) legitimate company or agency of authority, such as the IRS. Pharming redirects Web site traffic to fraudulent Web sites that distribute malware, collect personal data, sell counterfeit products, and perpetrate other scams. A rogue antivirus exploit usually begins with a virus warning and an offer to disinfect the infected device. Some software is not exactly malware, but it is a nuisance. A PUA takes up residence on a digital device and seems impossible to disable or remove.
