What is Digital Security?
Digital security is a wide-ranging field that protects computers, software, data and information systems against computer viruses, malware, cyber attacks and other threats. It includes cyber defences such as firewalls and other network architecture, encryption and verification tools, and more.
It also includes physical security, which encompasses a range of measures to protect electronic and other information assets from environmental hazards as well as intentional encroachment or terrorism. Fire safety, surveillance systems, armed guards and other physical security measures are commonly employed for this purpose.
The goal of many cyber attacks is to steal sensitive information for financial gain. This can include trade secrets or other valuable intellectual property. Such information may be used to extort money from victims, hurt the business of a competitor or simply disrupt the daily operations of an organisation.
In order to mitigate such attacks, the use of strong passwords and other basic digital security techniques is essential. However, for more advanced protection, encryption is an important tool. This involves encrypting data packets to prevent unauthorized users at either end from deciphering them. For this reason, we recommend using tools such as VPNs (Virtual Private Networks) and Tor – both of which provide multi-layer encryption, delete cookies and trackers, and offer anonymous internet browsing.
In addition, the use of two factor authentication is also recommended – this involves something you know (such as your password or PIN), and something you have (a card, dongle or cellphone) in order to log in. Similarly, training employees on password hygiene and the importance of recognizing social engineering attacks can help to turn them into a human firewall.
