Did you know that in 2018, Singapore suffered its largest-ever data breach in history when 1.5 million patients of SingHealth's specialist outpatient clinics had their personal information stolen? This included names, NRIC numbers, dates of birth, and even addresses. However, a couple of years after this event, cyber attacks have not gone away. In fact, not long since its occurrence, the Cyber Security Agency of Singapore (CSA) reported a 51.7% increase in cyber attacks.
With more frequent data breaches expected in the near future, CSA has underscored the need for consumers to exercise constant vigilance and improve data security to keep increasingly sophisticated threats at bay. Here are five ways you can enhance data security at home.
1. Encrypt Your Data
The safest way to secure your private data is to utilise encryption to make it indecipherable for people other than those that are authorised to access it. Encryption takes your data and then converts it into an unreadable form, thus maintaining the privacy of your records.
You can begin by activating an encryption tool and enabling it across all your connected devices. This way, your data will be secure even in the event that the devices are stolen or lost. In addition, ensure that you only visit websites that have SSL encryption. SSL encrypted websites are visibly distinguished as their URL starts with "https://" and has a padlock icon that precedes the name of the domain in the address bar of your web browser.
2. Update Your Software
In today's environment of hyperconnected and multi-platform devices, manufacturers go to great lengths to ensure connected devices are as user-friendly as possible. One adverse result of this is that software changes sometimes take place in the background, making it easy to lose track of their status.
An overwhelming bulk of hardware-related cyber attacks take place due to unpatched software vulnerabilities that cybercriminals use to obtain backdoor access to your system. If you ignore software updates, you are practically opening doors to hackers to infiltrate your system.
For this purpose, you should keep all software on your device as updated as possible. Alternatively, you can allow automatic updates to ensure your devices are protected at all times. These updates include fixes for newly found security vulnerabilities that could be exploited by malicious actors.
3. Backup Your Data Regularly
In light of persistent risks to your private information, it is likely that no protection will be 100% safe. This is particularly true in the face of the recent exponential increase in ransomware attacks in Singapore. They provide evidence that cybercriminals can pose just as much a challenge by refusing you access to your private data as they can by hacking and stealing it for themselves.
This is why it's important to back up all your critical data regularly so that you can easily recover from data breaches should they happen. You can do this by backing up your local data to cloud-based backup services. In addition, you can also run an antivirus software on your PC to keep it infection-free. This will decrease the probability of experiencing a ransomware attack and also alert you to issues before they can be replicated in your backup data.
4. Create Strong Passwords and Change Them Often
Singaporeans are lax when it comes to password security, as reported in a study conducted by the CSA. The report stated that 33% of respondents store their passwords in their computer and use the same password for multiple accounts. Moreover, between 50-70% of respondents don't change their passwords until prompted by their online service providers.
With cybercriminals getting smarter, it's best to not leave internet security to chance and create strong passwords while ensuring you change them frequently. This allows you to sidestep brute-force attacks, where malicious actors use a number of password variations in the hope of guessing a combination correctly. If you feel password management is a hassle, you can use a password manager to store your passwords and access them with one master password whenever you want.
5. Invest in Antivirus Software
An antivirus software solution is a crucial component of your broader system security plan and is the best way to enhance data protection. It discovers hidden viruses, points you to possible risks in your system, and then deletes them before they can corrupt your data. This ensures that almost all threats are stopped before they can deal any damage to your systems.
A powerful antivirus software solution like ESET NOD32 Antivirus also protects you against malicious websites and ads, which are the most popular gateways through which viruses infect your systems. This eliminates the risk of a data breach due to a ransomware attack by restricting its immediate access to your computer network.
