Final answer:
The unknown technician inquiring about the network may be engaging in social engineering, a common tactic among hackers to manipulate individuals into divulging confidential information. These attacks can lead to data breaches and compromise sensitive information. Mitigating such threats involves strong security measures and employee education on cybersecurity.
Step-by-step explanation:
The employees at the financial department who reported an unknown technician asking questions about the network might be observing a type of security threat known as social engineering.
Social engineering is a tactic used by hackers to gain access to systems or information by exploiting human psychology, rather than using technical hacking techniques.
In the situation described, it appears the attacker is attempting to gather sensitive information that could lead to unauthorized access or a data breach.
Hackers use various methods in their attacks, including but not limited to phishing, installing malware, exploiting software vulnerabilities, and conducting Denial of Service (DoS) attacks.
They might steal personal data, financial information, intellectual property, or national security details. Such information can be used for financial gain, identity theft, espionage, or to weaken security systems further.
To combat these threats, organizations should employ a robust security protocol, educate employees on cybersecurity awareness, and use technology such as firewalls, anti-virus software, and intrusion detection systems.
