Adopting a layered approach to phishing

Phishing remains one of the primary methods attackers use to target organisations. Findings contained in the Department for Digital, Culture, media & Sport’s Cyber Security Breaches Survey 2019 indicate that, a third (32%) of businesses and two in ten charities (22%) report having cyber security breaches or attacks in the last 12 months. And despite the technical advancements made, 80% of these businesses fell victim to a phishing attack. 

The IT Insider caught up with Celerity who told us that adopting a layered approach can help. 


Adopting a multi-layered approach to stop phishing attacks

Traditionally, defending against a phishing attack often relied on an individual spotting a malicious email. Yet training alone can’t and won’t protect you from phishing. Stopping phishing attacks requires a layered approach which combines both employee education and technical controls. As such, widening your defences will improve your resilience against phishing attacks without disrupting the productivity of your users and will help you plan for incidents, and minimise the damage caused.

Guidance from the NCSC suggests a four-point-multi-layered approach.

Layer 1: make it difficult for attackers to reach your users

You can reduce the likelihood of false emails landing in your inbox by implementing security solutions as your first line of defence. Filtering services usually send email to spam/junk folders, while blocking services ensures that they never reach your user. The rules determining blocking or filtering need to be fine-tuned for your organisation's needs. Further to this, employing anti-spoofing controls will make it harder for your email to be spoofed.

Layer 2: Help users identify and report suspected phishing emails

Educating your employees is vital to ensuring that phishing emails don’t dupe any unsuspecting stakeholders. Informing your users about the nature of the threat posed by phishing and explaining the common features of phishing mails are all important statements to get across. This can be further reinforced by undergoing phishing simulations.

Layer 3: protect your organisation from the effects of undetected phishing emails

Malware is often hidden in phishing emails, or in websites that they link to. To counter-act this, ensuring that your business uses supported software and devices is vital; as is making sure your software and devices are kept up-to-date regularly with the latest patches.

Layer 4: respond quickly to incidents

When it comes to cyber security attacks, it’s a case of when not if your company is targeted. Knowing about an incident sooner rather than later allows you to limit the harm it can cause. By having a structure in place whereby users know how to report incidents along with logging all attempted attacks, will provide visibility and will inform key stakeholders about the threats posted. Further to this, having an incident response plan will let prevent any further harm.
