We regularly cover internet security and high profile hacks on our blog, but how can you stay safe from hackers? Here are some internet security tips to stay safe online.
Use a firewall
A firewall is a hardware or software barrier that sits between computer networks. They are used between areas that are trusted – such as your own corporate network – and untrusted – such as the internet. A firewall offers protection by controlling traffic that enters and leaves the network using a series of rules (or filters) set by the user. By blocking certain types of traffic, a firewall can protect against hackers accessing your systems.
Keep software updated
Any software – especially your operating system and web browser – on all your devices: computers, tablets and mobile devices – must be kept up to date. Publishers release regular patches to correct faults in the software that can be exploited by criminals. Older software must be replaced if it is no longer supported with security updates. For example, the devastating global WannaCry attack targeted an older version of Windows that had been patched but many users had not yet downloaded and installed the update.
Use a strong password
Some hackers access systems by using software. Such a “brute force” attack tries every combination of letters and numbers until they find a password that matches. They begin by using words from the dictionary so never use a single word as your password. Every extra character and number you add to your password exponentially improves its security. Often, breaches of security happen because passwords are not changed from the default one that ships with a device or piece of software. That is why you should always change passwords on new routers etc. as soon as they are installed on your network.
