Keeping your IT systems safe and secure can be a complex task and does require time, resource and specialist knowledge. If you have personal data within your IT system you need to recognise that it may be at risk and take appropriate technical measures to secure it. The measures you put in place should fit the needs of your particular business. They don’t necessarily have to be expensive or onerous.
Keep you and your systems up-to-date
Computer equipment and software needs regular maintenance to keep it running smoothly and to fix any security vulnerabilities. Security software such as antivirus and anti-malware needs regular updates in order to continue to provide adequate protection.“
Cyber criminals or malware can attack your systems and go unnoticed for a long time. Many people only find out they have been attacked when it is too late even though the warning signs were there.
