It focuses on teaching employees and stakeholders how to recognize potential threats, respond appropriately, and implement security measures to protect sensitive information and systems. By enhancing awareness, organizations aim to cultivate a security-conscious culture that reduces the likelihood of security breaches and data loss.
Social Engineering: Social engineering is the psychological manipulation of people into performing actions or divulging confidential information, often for malicious purposes. This practice exploits human emotions such as trust, fear, or curiosity to gain unauthorized access to systems or sensitive data. It plays a significant role in cybersecurity and privacy concerns as it can lead to significant breaches in security and compromised personal information.
Surveillance: Surveillance refers to the monitoring and observation of individuals, groups, or systems, often with the intent to gather information, ensure security, or control behavior. In today's digital age, surveillance has expanded significantly due to advancements in technology, leading to various implications for privacy and cybersecurity. This heightened level of monitoring raises concerns about individual rights and the balance between security needs and personal freedoms.
Symmetric encryption: Symmetric encryption is a method of cryptography where the same key is used for both the encryption and decryption of data. This means that both the sender and the receiver must possess the secret key to communicate securely, making it a foundational technology in cybersecurity. Its efficiency and speed make it ideal for encrypting large amounts of data, but it also raises challenges around key management and distribution, especially in protecting privacy.
Trojan: A Trojan, or Trojan horse, is a type of malicious software that disguises itself as a legitimate program to trick users into downloading and executing it. Once installed, it can create backdoors for attackers, steal personal information, or take control of the infected system. Trojans highlight significant vulnerabilities in cybersecurity and raise privacy concerns regarding unauthorized access to sensitive data.
Two-Factor Authentication: Two-factor authentication (2FA) is a security process that requires two different forms of identification to access an account or system, enhancing protection against unauthorized access. This method combines something you know, like a password, with something you have, such as a mobile device or hardware token. By requiring multiple verification steps, two-factor authentication significantly increases the difficulty for attackers to compromise accounts.
Viruses: Viruses are microscopic infectious agents that can only replicate inside the living cells of an organism. They consist of genetic material (DNA or RNA) surrounded by a protein coat and, in some cases, a lipid envelope. In the context of cybersecurity, viruses are a significant threat as they can infect computer systems, leading to data breaches, system damage, and loss of privacy.
Vulnerability assessment: A vulnerability assessment is a systematic process used to identify, evaluate, and prioritize vulnerabilities in a system, network, or organization.
