Action to strengthen IS security in order to prevent further intrusion by an attacker.
Here are a few examples of cyber security measures:
- Updating software and operating systems Install the latest security updates to correct known vulnerabilities.
- Secure configuration Modify the default settings of systems and software to make them less vulnerable to attack.
- Access control Restricting access to sensitive systems and data to authorised personnel only.
- Use of strong passwords Create complex and unique passwords for each account.
- Regular back-ups Backup: Make regular backups of important data so that it can be restored in the event of an attack.
- Staff training Raising staff awareness of good safety practices and potential risks.
- Surveillance and intrusion detection Implement surveillance systems to detect suspicious activities and ongoing attacks.
Hardening tools
- Firewalls To filter network traffic.
- Antivirus To detect and remove malware.
