Cyber and terrorist attacks

Cyber-attacks

A cyber-attack is an attempt to steal, expose, alter, or destroy information through unauthorised access to computer systems. 

Cyber criminals are motivated by financial gain through money theft, data theft or business disruption.

Be ready for a cyber-attack

  • install internet security on your laptop, tablet or PC. Find out how to do this on the National Cyber Security Centre website
  • do not reuse the same password on different online accounts
  • review your social media privacy settings to reduce what other internet users can find out about you
  • do not give out your personal information unless you are sure it is a legitimate source
  • destroy receipts with your card details on and post with your name and address on
  • keep a back-up of any important documents 

Businesses - stay safe during a cyber-attack

Terrorist attacks

The possibility of a terrorist attack in York and North Yorkshire is low. It is however important to be alert to any individual who might want to put the public in danger.

Be ready for a terrorist attack

If you come across anything you suspect might be linked to terrorist activity, tell the police:

Threat levels

There are five threat levels:

  1. Low - an attack is highly unlikely.
  2. Moderate - an attack is possible but not likely.
  3. Substantial - an attack is likely.
  4. Severe - an attack is highly likely.
  5. Critical - an attack is highly likely in the near future.

The level is set by the Joint Terrorism Analysis Centre and the Security Service, MI5.

Threat levels do not have an expiry date. They can change at any time as different information becomes available. 

Stay safe during a terrorist attack

Follow the government's Run, Hide, Tell advice - for details visit the Protect UK website.

Run

  • consider the safest options and escape if you can
  • if there is not a safe route, you need to hide

Hide

  • find cover from gunfire
  • if you can see the attacker, they may be able to see you. Being hidden from view does not mean you are safe. Bullets go through glass, brick, wood, and metal. You must still hide, even if you are behind a locked door
  • be aware of your exits and try not to get trapped
  • make sure you stay quiet and silence your phone

Tell

  • call 999 - what do the police need to know about what is happening? 
  • if you cannot speak or make a noise, listen to the instructions given to you by the call responder 

Communities - be ready for a terrorist attack

  • encourage people to be alert
  • share emergency plans
  • include details of Run-Hide-Tell in local safety talks 

Businesses - be ready for a terroristist attack
