Introduction
As our dependence on the internet grows, so does the vulnerability to cybersecurity risks. According to a cyber security provider in Singapore, approximately every thirty-nine seconds, an attack occurs globally, indicating an escalating threat.
Cybercriminals continually refine their methods, becoming more sophisticated in targeting individuals. Being aware of the circumstances that heighten your vulnerability to a cyber breach and recognizing signs of fraud can reduce the risk of falling victim to cybercrime.
1: Update Your System and Software
Viruses have evolved a lot to exploit the weaknesses in software, making regular updates and security patches crucial for device safety.
Therefore, it’s vital to allow consistent system updates and trusted software/app updates. If a device or program is no longer supported by its manufacturer, it’s advisable to upgrade to newer options.
Also try to replace devices when they’re unable to receive the latest operating system updates, typically after 5-8 years, to ensure security capabilities remain up to date.
2: Use an Antivirus or a Firewall
Many computers tend to include built-in antivirus protection within their operating systems, emphasising the importance of regular updates for security software and operating systems.
Yet, for business computers often targeted by hackers, opting for an additional free or paid antivirus system is advisable.
Security.org suggests that having backup antivirus software adds an extra layer of security, highlighting the benefit of redundancy in digital security.
3: Be Cautious with Emails and Links
Phishing attacks often occur through deceptive emails and malicious links.
So, exercise caution before clicking on links or downloading attachments, especially if they’re from unknown or suspicious sources.
Also, check for spelling errors, unexpected requests for personal information, and verify the sender’s legitimacy before taking any action.
4: Secure Your Wi-Fi Network
Your home Wi-Fi network is a gateway to your devices. Replace the default username and password that you had before to unique and robust credentials.
Use WPA3 encryption, and consider hiding your network’s SSID to prevent unauthorized access. And, be sure to update your router’s firmware daily to patch potential vulnerabilities.
5: Have a Proper Backup of Your Data
Backing up your data is crucial for cybersecurity for two primary reasons.
Firstly, in the event of a virus or malware rendering your computer unusable, having backups ensures swift retrieval of important files, even if antivirus measures fail and a complete hard drive wipe is necessary.
It guarantees a seamless continuation, especially with critical financial records.
Secondly, protection against ransomware is vital.
If your system falls victim to ransomware and your data isn’t backed up, you might be forced to pay a ransom for access. However, there’s a high probability of not recovering files even after payment, potentially leading to file corruption or irreversible damage to your computer.
With proper backups in place, you can circumvent engaging with cybercriminals and restore your data without compromise.
6: Use Passwords (Strong Ones)
A robust password should be lengthy and include a mix of upper and lower case letters, numbers, and symbols.
If a password can be easily guessed using personal information or interests, it’s not secure enough, especially for business accounts.
For added security, consider using a password manager.
These tools not only aid in remembering passwords but also generate highly complex ones that are nearly impossible to guess.
They securely store passwords and often employ multi-factor authentication, ensuring only authorized access. PC Magazine recommends several trustworthy password managers.
7: Activate Multi-Factor Authentication
As previously mentioned, multi-factor or two-factor authentication (MFA/2FA) offers an extra security level beyond just passwords. It mandates an additional verification—often via another trusted device—to grant access to an account.
For instance, logging into a Google Account might prompt you to confirm the login through a linked smartphone. How impactful is MFA? It can thwart 80-90% of cyber-attacks.
While its activation might be mandatory in some cases, it’s occasionally presented as an optional feature. When given the choice, it’s highly advisable to enable MFA.
