We provide an A to Z of cyber security terms or meanings you should know (a set of straightforward definitions).

App
Some of the most common Apps

 

app

Short for Application, typically refers to a software program for a smartphone or tablet.

B 

Botnet_Attack
Example Botnet Attack

 

botnet

A network of infected devices, connected to the Internet, used to commit coordinated cyber-attacks without their owner’s knowledge.

 

breach

An incident in which data, computer systems or networks are accessed or affected in a non-authorised way.

 

browser

A software application which presents information and services from the web. See this article on the best browsers for 2020.

 

brute force attack

Using a computational power to automatically enter a huge number of combination of values, usually in order to discover passwords and gain access.

 

bring your own device (BYOD)

An organisation’s strategy or policy that allows employees to use their own personal devices for work purposes.

 

C 

certificate

A form of digital identity for a computer, user or organisation to allow the authentication and secure exchange of information.

 

 

cloud

Where shared compute and storage resources are accessed as a service (usually online), instead of hosted locally on physical services. Resources can include infrastructure, platform or software services. Best cloud storgage free, paid and business.

 

credentials

A user’s authentication information used to verify identity – typically one, or more, of password, token, certificate.

Authentication is the process of determining whether someone or something is, in fact, who or what it declares itself to be. Authentication technology provides access control for systems by checking to see if a user’s credentials match the credentials in a database of authorized users or in a data authentication server.

 

cyber attack

Malicious attempts to damage, disrupt or gain unauthorised access to computer systems, networks or devices, via cyber means.

Follow these 10 Steps to Cyber Security, common cyber attacks.

 

cyber incident

A breach of the security rules for a system or service – most commonly;

  • Attempts to gain unauthorised access to a system and/or to data.
  • Unauthorised use of systems for the processing or storing of data.
  • Changes to a systems firmware, software or hardware without the system owners consent.
  • Malicious disruption and/or denial of service.

cyber security

The protection of devices, services and networks — and the information on them — from theft or damage. Need to know who’s best, what they offer?

 

D

data at rest

Describes data in persistent storage such as hard disks, removable media or backups.

 

dictionary attack

A type of brute force attack in which the attacker uses known dictionary words, phrases or common passwords as their guesses.

 

digital footprint

 

digital footprint

A ‘footprint’ of digital information that a user’s online activity leaves behind.

 

denial of service (DoS)

When legitimate users are denied access to computer services (or resources), usually by overloading the service with requests.

 

download attack

The unintentional installation of malicious software or virus onto a device without the users knowledge or consent. May also be known as a drive-by download.

 

E

encryption

A mathematical function that protects information by making it unreadable by everyone except those with the key to decode it.

 

end user device (EUD)

Collective term to describe modern smartphones, laptops and tablets that connect to an organisation’s network.

 

exploit

May refer to software or data that takes advantage of a vulnerability in a system to cause unintended consequences.

 

F

Hardware or software which uses a defined rule set to constrain network traffic to prevent unauthorised access to or from a network.

 

G

H 

hacker

In mainstream use as being someone with some computer skills who uses them to break into computers, systems and networks.

 

honeypot (honeynet)

Decoy system or network to attract potential attackers that helps limit access to actual systems by detecting and deflecting or learning from an attack. Multiple honeypots form a honeynet.

 

I

incident

A breach of the security rules for a system or service, such as:

  • attempts to gain unauthorised access to a system and/or data
  • unauthorised use of systems for the processing or storing of data
  • changes to a systems firmware, software or hardware without the system owners consent
  • malicious disruption and/or denial of service

Blackpool Grand Theatre

Take a look at what’s on at Blackpool Grand Theatre this Autumn / Winter 20/21

 

Blackpool Grand set out a COVID-Community Communication Programme (CCCP) during the Coronavirus pandemic. Our aims were simple, to CONNECT, COMFORT and UPLIFT. We would Connect people by offering tutorials on communication tools like Zoom and conduct community face-to-face meetings (book readings, youth groups and more). Comfort through stories of heritage, memories and storytelling, and to Uplift visitors spirits through laughter and exercise. Please do enjoy and if you can afford to donate please do.

 

The information in this story is accurate as of the publication date. While we are attempting to keep our content as up-to-date as possible, the situation surrounding the coronavirus pandemic continues to develop rapidly, so it’s possible that some information and recommendations may have changed since publishing. For any concerns and latest advice around COVID-19, visit the World Health Organisation. If you’re in the UK, the National Health Service can also provide useful information and support, while US users can contact the Center for Disease Control and Prevention.
