Basic Terminologies in Cybersecurity Source: Canva Pro
Cyber security is a broad field with many terminologies, each significant in understanding how to protect computer systems and networks from cyber threats.
These are some basic terms that are essential to know:
Malware : Short for “malicious software,” it refers to any software intentionally designed to cause damage to a computer, server, client, or computer network. Examples include viruses, worms, Trojan horses, and ransomware.Virus : A type of malware that, when executed, replicates by inserting copies of itself into other computer programs, data files, or the boot sector of the hard drive.Phishing : A cybercrime in which targets are contacted by email, telephone, or text message by someone posing as a legitimate institution to lure individuals into providing sensitive data such as personally identifiable information, banking, and credit card details, and passwords.Firewall : A network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet.Encryption : The process of encoding information. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Ideally, only authorized parties can decipher a ciphertext back to plaintext and access the original information.Ransomware : A type of malicious software designed to block access to a computer system until a sum of money is paid.Spyware : Software that enables a user to obtain covert information about another’s computer activities by transmitting data covertly from their hard drive.Cybersecurity : The practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks.VPN (Virtual Private Network) : A technology that creates a safe and encrypted connection over a less secure network, such as the Internet.DDoS (Distributed Denial of Service) : An attack that aims to disrupt the normal traffic of a targeted server, service, or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. Understanding these terms can help you better grasp the basics of cyber security and the measures needed to protect digital assets.
What is The CIA Triad? The CIA Triad is a widely recognized model for cyber security that outlines three fundamental principles to guide information security policies and measures.
These principles are:
Confidentiality : Ensures that data and information are protected from unauthorized access or exposure. This is often implemented through methods such as encryption, access controls, and secure communication protocols to ensure that only authorized individuals can access sensitive information.Integrity : Ensures that data is accurate and unaltered during storage, transfer, and processing. Techniques such as checksums, hashes, and digital signatures are used to detect any unauthorized changes to the data. Maintaining data integrity helps to ensure that information remains correct and trustworthy.Availability : Ensures that data and resources are accessible to authorized users when needed. This involves protecting against attacks that may render information systems unusable, such as denial-of-service attacks, and also implementing backup and disaster recovery plans to ensure that critical systems can continue operating during and after an incident. Together, these principles form the foundation of most cyber security programs and strategies, emphasizing the importance of protecting information from unauthorized access, ensuring the accuracy and reliability of data, and maintaining the usability of systems.
