Cybersecurity is the technology that protects your personal and professional data from hackers, ransomware, phishing scams, identity theft and other threats. It involves safeguarding your digital assets, which include computers, smart devices, routers and networks, from unauthorised access or damage. It also covers defending against the theft of sensitive information, including proprietary, financial and client data.

For businesses, it helps in improving operational efficiency by eliminating downtime from malicious attacks that could otherwise halt production. It can reduce the risk of loss of business data by securing systems with antivirus software, firewalls and other security measures. Cybersecurity can help prevent internal fraud by employees, such as stealing company data or accessing customer information and passwords. It can help prevent data breaches and build an organisation’s cyber resilience against DDOS attacks.

Keeping up with software updates can help keep malware and other threats at bay. Using two-factor authentication and backing up your data can add another layer of protection against cyberattacks. It’s also important to be cautious when opening attachments or clicking on links in emails. Educating employees about email phishing, scams and suspect links can cut down on productivity-halting incidents.

The need for cybersecurity experts is increasing as hackers become more sophisticated and attacks occur at a higher rate. It’s crucial to protect modern-day essentials like power grids and water treatment plants from attackers, who can take down the very systems we rely on for survival.
