Anti-virus software and ad blockers are common tools to increase your data security on your device. To mark today’s Computer Security Day, here are five more tips on how to improve your computer security.

1. Check before click

Most people get them every day; so-called phishing mails. Mostly disguised as sinfully cheap offers from well-known companies, they want to entice the user to click on a link given in the mail. Via this link, the scammers are able to grab sensitive data such as passwords or install malware.

In the meantime, some mail providers are already filtering out most of these messages. However, if you are not sure whether an email is legitimate, it is better not to click on it in the first place.

2. Don’t recycle your passwords

Remembering one or two passwords is not a problem for most people. Having one for every account is far too many to remember.

In such cases, the “solution” seems quite obvious: simply use the same password several times so that you don’t have to click on “Forgot your password?”. However, this may become really dangerous if the universal password is stolen. Especially if sensitive data, such as the PayPal account, is protected with them.

A password manager can provide a remedy, as it generates and saves all passwords for you.

3. Attention with Wi-Fi

They can be extremely practical. We’re talking about public Wi-Fi networks: quickly answer an email on the train or do your work from the café around the corner.

However, these public networks are usually not encrypted. This means that anyone could theoretically read the data stream between their own device and the network and, in the worst case, even damage the device.

It is therefore advisable to have a VPN set up when using public networks.

4. Protect your browser

Browsers are the gateway to the Internet, so it is all the more important to protect them properly. A first step towards more security while surfing is to always keep the application up to date. This way, security gaps can be constantly closed.

In addition, plug-ins to protect against phishing and malware can increase the security of your browser. These can be activated relatively easy with most providers.

5. Secure on the go in the cloud

Uploading your own data to the cloud can be very handy, for example, if you want to quickly share pictures or expand your own storage space. But when the data is uploaded to the cloud “just like that”, it is not safe from strangers’ eyes. The reason is quite simple; the data is unprotected in the cloud; once someone has gained access, they can simply access all the data without any obstacles. This can be easily avoided; Cryptomator puts your data in the cloud in a secure safe and thus protects it from foreign eyes.
