Cybersecurity Professionals

Both terms refer to newly discovered vulnerabilities without patches; insiders use the term '0-day exploit' emphasizing the active attack exploiting the vulnerability.

Outside the community, any attack may be called a cyber attack, while insiders reserve 'APT' to describe sophisticated, sustained attacks by capable adversaries.

Outsiders may vaguely understand red teaming as penetration testing, but insiders view it as a full adversary simulation including tactics and strategies.

Casual observers mention passwords, but professionals use 'credential' to include not only passwords but other forms like tokens or biometric data for authentication.

The general public often uses 'encryption' to mean data protection, but professionals include 'cryptography' as the full field encompassing encryption, hashing, and related algorithms.

Non-experts say data leak casually, but professionals use 'data exfiltration' to describe the intentional unauthorized removal of data by attackers.

Laypeople use 'virus scanner' to describe basic antivirus software, while insiders prefer 'EDR' systems that provide real-time monitoring and advanced threat detection on endpoints.

Casual users see password resetting as a simple action, but for professionals it is part of IAM protocols to control and audit user access.

Non-experts often call all harmful software 'viruses,' whereas cybersecurity professionals use 'malware' to refer to all types of malicious software including viruses, worms, ransomware, etc.

Casual users think of a firewall as a single device blocking unauthorized access, but professionals understand it as part of a multilayered network perimeter defense strategy.

Casual users say 'hacking' broadly, but professionals use 'penetration testing' to describe authorized controlled attacks to find vulnerabilities.

Casual observers think antivirus software is the main defense, but professionals emphasize SOCs as centralized units monitoring and responding to threats.

'Phishing' is a common term, yet insiders categorize it within the broader 'social engineering attacks' that manipulate human behavior to gain unauthorized access.

Casual use 'hacker group' for any organized attackers, while insiders use 'threat actor group' for classified entities involved in cyber operations.

Outside observers may call all malicious intruders 'hackers,' while insiders use 'threat actors' to include various types of adversaries with different motives and capabilities.

Laypeople use 'bug' generally for software defects, whereas cybersecurity experts specify 'vulnerability' for flaws that enable security breaches.

Laypersons call it bug bounty programs, while experts use 'vulnerability disclosure program' to cover coordinated reporting and rewards.

Casual participants refer to 'white hats,' but professionals prefer 'ethical hacker' to emphasize legal and authorized security testing.

Outsiders say 'black hat' for any criminal hacker, professionals use 'malicious hacker' to describe unauthorized actors focused on harm.

Outside the community, any software fault is called a bug; insiders use 'CVE' to designate officially catalogued vulnerabilities with standardized identifiers.
