A human firewall is the answer to prevent phishing

When it comes to phishing attacks, businesses often can’t deploy security technology fast enough to keep cybercriminals at bay – which is why the ultimate protection comes in the form of a combination of security technology and a human firewall.

A human firewall is created when individuals within an organisation are educated about how to interrogate their emails: when to click on a link or open an attachment, and when to delete it.

IT security technology can reduce spam and block most malicious emails, but cyber-criminals are using social engineering to prey on unsuspecting email recipients.

This can be done by sending spoofed emails that use existing company or people’s names with malicious links designed to extract sensitive information like computer login details or personal information.

These emails are often difficult to block because they are designed to surpass the usual firewalls.

They don’t use the usual set of spam words (for example, Viagra) which are flagged and blocked, and they are so targeted that the content or ‘sender’ is usually unknowingly welcomed by the recipient.

This is where the human firewall comes in. Mimecast’s enhanced Targeted Threat Protection teaches people why links are malicious when they click on them, by alerting them to the URL which may look legitimate, but isn’t.

Mimecast is helping businesses build a human firewall while encouraging decision makers to do their part by educating their staff about the dangers of sharing personal information via malicious links.

According to Wolfpack Risk’s Cyber Threat Barometer report, the estimated price tag of cybercrime is estimated as high as R662.5 million per year in South Africa.

Mimecast offers strong security technologies, using an adaptive approach to essentially shut down email as a vector of attack.

It only takes one wrong click to compromise an entire network, and the human is the often the weakest link when it comes to maintaining a good security framework – so empowering the user to make safe choices is key.

A two-pronged strategy of education and automation is critical to creating a safe, effective ‘human firewall’.
