Keep On Top Of Security Updates At All Times

Perhaps one of the most difficult methods of security is getting your users to remember those dreaded updates. Often seen as a hassle, a lot of us just don’t see the importance of regularly updating our operating systems.

Then, in came WannaCry…

The hugely damaging ransomware attack shook the NHS and all started due to a delayed Windows update that went on to affect hundreds of thousands of computers. If Wanna-cry taught us one thing, it’s that staying on top of software updates is the most prudent way to protect yourself against hackers and cyber criminals.

Turn Off File-sharing And Close Shared Files On Your computer

Sharing folders can be a great way of working collaboratively with your team, as well as sharing photos with friends and family. But one thing that many of us don’t realise, is that once your computer connects to a public Wi-Fi, those folders can be viewed by anyone else on your network.

Make sure to close them and turn off file-sharing before logging onto a public network with your laptop or mobile device. Also, adjusting your privacy settings to ensure they are different for public and private networks is important to remember.

When you use file-sharing networks you can potentially open up your PC to a host of malware threats such as worms, Trojans, key loggers, spyware, adware and more, if you do not understand how to protect your PC when using file-sharing networks.

Identity theft

Sharing files over a public WiFi networks increases the chances of anyone having access to them, even by accident. If someone has the skills to intercept the network they could potentially send all of the files to them or even make a copy of them without the sender even knowing.

Once the cyber criminal has access to this data they can commit identity theft and gain access to your personal accounts and steal any money or data they want.

Avoid signing into accounts that contain personal information, including social media and online banking.

Assuming that you’ve taken precautions beforehand, the next step is to be cautious after logging onto a public network. One of the best ways to play it safe is to avoid logging into any accounts that contain personal information, such as social media, work email and especially, online banking.

The best way to remember this is that even though a website itself might be reputable, personal information still isn’t secure as long as the network is insecure.
