COVID-19 CYBER AND FRAUD PROTECT MESSAGES


Monday 18 May 2020

This advice has been collated by EMSOU and is intended for wider distribution within the East Midlands Region to raise awareness among businesses and the public.

Advice and information is changing daily as we navigate our way through the COVID- 19 pandemic, so please ensure you only take information from reputable sources.

If you require any further information, assistance or guidance please contact the EMSOU Protect Team or your local Force protect team. As society has become more complicated, humans have had to develop new ways to authenticate people they don’t directly know. When you know someone, it’s easy to identify them by simply looking at them. Over time, authentication has become more complex. In today’s blog, we’re discussing Multi-Factor Authentication (MFA) as a way to increase your company’s cyber security.

For up-to-the-minute information about cybersecurity throughout the COVID-19 crisis, remember to subscribe to our email newsletter. What is Multi-Factor Authentication?

Multi-factor or, more commonly, two factor authentication (2FA) is an extra layer of security for online activity. We have been using 2FA for years; when you put a debit card (something you have) into an ATM, it needs a PIN (something you know), but there are additional authentication levels that can be used for additional security.


Location is one layer and organisations may limit access to data to those within a secure network or by a specific device. A GPS-derived location from a smartphone or IP address may also be used to limit access. Some media sites use this to limit programmes broadcast by geographic region.

Other layers of authentication may be time based - only allowing access to users at certain designated times. Banks may use time and location for checking withdrawals - it’s impossible to withdraw from an ATM in London and 45 minutes later from an ATM in Glasgow, for example.

Biometric authentication is another layer – facial recognition, fingerprint, voice recognition and retinal scan. By applying multiple variations of these factors, it is possible to greatly increase the security of systems and data accessed.

The most common MFA is 2FA; a text message is sent to a mobile phone while using a bank/credit card online and a code is entered to authorise the transaction. This also imposes a time limit for using the code, to prevent fraudsters using the same code later.

MFA provides a way of 'double checking' who you really are when using online services, such as banking, email or social media.

When setting up 2FA, the service will ask for a 'second factor', which is something that you (and only you) can access - a code sent by text message or created by an app.


• Text messages. During setup, provide the phone number, and the service will send a code to use. Some services also offer sending a code using a voice message.


• Authenticator Apps on a smart phone (or tablet) are the main alternative to text messages. Google Authenticator and Microsoft Authenticator are examples. Apps offer advantages, such as not needing a mobile signal, or waiting for a text message to arrive.


The option to switch on MFA is usually found in security settings, it may be called 'two-step verification'.

Top tips


• Use MFA when online, as it significantly reduces the risk of fraud.

• The website www.telesign.com/turnon2fa/tutorials contains up-to-date instructions on how to set up 2FA across popular online services such as Gmail, Facebook, Twitter, LinkedIn, Outlook and iTunes.

• Do not to publicise your mobile phone number on social networking sites and if your phone line goes down, contact your service provided immediately.
