WannaCry Cyber-Attack – What to do Next
Simple precautions to protect your information
Last week’s cyber-attacks saw hospitals and GP surgeries across Britain hit by a ransomware attack which crippled their systems. Malware known as WannaCry (also known as Wana Decrypt0r 2.0) scrambled data on computers around the world and demanded payments of $300-$600 to restore access.
So what should you and your business do now? Here are some simple tips for protecting your data through pre-infection protection and post-infection recovery readiness:
- System and Application Updates – implement an effective patching strategy for all devices and applications throughout your organisation
- Access control and User Privileges – restrict access and apply appropriate user permission levels on a least access and need to know basis
- Antivirus and Firewalls – set up correctly, enable and keep up to date
- Backups – perform regular backups, check all important data is included, check that these are successful, store offline and periodically test restoration of data
- Policies and Procedures – ensure these are up to date, that they are effective and that users are familiar with them
- Password Security – ensure an effective policy is in place and that it is enforced
- Phishing Prevention – ensure users know only open emails from known senders and if unsure, speak to the sender to check
- Incident Response Planning – a simple plan is better than none at all. Ensure staff know who to contact for advice and support.
