Social engineering

Social engineering attacks exploit human psychology to manipulate individuals into divulging confidential information or performing actions compromising security. Attackers commonly use techniques such as pretexting, baiting, and tailgating to deceive victims.

Organizations must train employees to recognize social engineering tactics and implement security products and controls to mitigate the risk.

Some common types of social engineering include:

1. Pretexting: Attackers create a false pretext or scenario to deceive individuals into disclosing confidential information or performing actions they wouldn't typically do.
2. Baiting: Baiting involves enticing individuals with promises of rewards or benefits to trick them into downloading malware or disclosing sensitive information.
   

Top cybersecurity myths: Debunking misconceptions

Despite knowing what cybersecurity risk is, several myths persist in the public consciousness. Let's debunk ten common misconceptions:

1. Only large organizations are targeted by cyberattacks. In reality, cybercriminals target organizations of all sizes, including small businesses and individuals.
2. Antivirus software provides complete protection. While antivirus software is essential, it is not a silver bullet against all cyber threats. Additional layers of security are necessary for comprehensive protection.
3. Cybersecurity is solely the responsibility of IT departments. Cybersecurity is a collective responsibility that involves everyone in an organization, from employees to executives.
4. Cyberattacks are always technologically sophisticated. While some cyberattacks involve advanced techniques, many are relatively simple, exploiting human error or known vulnerabilities.
5. Cybersecurity is too expensive for small businesses. Implementing basic cybersecurity measures does not have to be prohibitively expensive. Many affordable solutions are available for small businesses.
