On Friday, 12th May 2017 a global cyber-attack hit 150 countries including the UK. 47 NHS organisations were affected in England and 13 in Scotland, creating widespread chaos and confusion.
This recent event has made people question their own cyber security measures and whether they are able to prevent such attacks. It is useful to take precautions when storing important data on your systems, no matter how small or big.
Below are some simple and easy tips you can do to protect your machines from any future viruses.
Every piece of software you use will have some security issues, it’s inevitable. Windows, Chrome, Firefox, Adobe, Internet Explorer and so on. A lot of these operating systems and programs have automatic updates which is recommended you leave these on. From a security perspective, keeping your computer up-to-date will keep it safe from online threats. I understand that updates can be very annoying, however, for the sake of protecting your data I think it is a worthy compromise.
Antivirus and Anti-Malware
It doesn’t matter which one you have, you must use it regardless. Windows Defender, which is a built in firewall for Windows is a perfect, free and simple program to use. Anti-Malware programs can help to assist with the antivirus and are also recommended. When set up properly, these firewalls protect your computer files from being scanned.
You need to make sure you are using strong passwords. This is vital, people nowadays use the same passwords for everything, which makes it very easy for anyone to hack into your systems and get a hold of your data. You need to have a separate password for everything, you also need to make sure your password isn’t obvious. A good password will have a combination of letters, numbers and special characters. This doesn’t just go for accounts etc. this means passwords to your laptop, computer and phone. Last but not least, always change your passwords on a regular basis.
Be well aware of phishing emails, even from people you know. They may have a virus themselves. Never click on a link in an email, if you want to investigate further, copy and paste the link into notepad and examine the address. If the email states that it is “google.com” however the actual link address says “google.clickme.com”. This is suspicious, and you should not open it.
Downloads and Pop-Ups
Any programs or software you download must be done from a well-known, trustworthy site. For example, if you need to download Adobe Flash, go to the official Adobe website and download it from there. Do not click on any other advertisements or banners saying that they can be downloaded. Always stick to those that are secure. The same goes for pop-ups; do not click on any that request you to download any programs you think you may already have. You might get a pop-up from a website asking you to update google chrome, do not click on this. Double check on your google chrome browser settings for updates, and update it from there.
You should be backing up your data on a regular basis. Monthly back-ups are a good idea, even if it means doing this on an external hard drive or USB. It is easier to retrieve the data if lost or stolen. Keep this back-up of data separate from your computer or laptop, just in case anything is taken. You may already know this, but you must never leave your laptop/phone/tablet unattended in public. It is so easy for someone to get a hold of it. At most, they have your expensive laptop (if you have followed all the protocols above they shouldn’t be able to hack your password). Although, if you leave it logged on, you have literally given the public access to your private, personal data. Please BE AWARE.
