+ EDITOR’S QUESTION JURGEN SORTON, SENIOR PRODUCT MANAGER FOR SECURITY AT VOX /////////////////// P hishing attacks are on the rise and show no signs of slowing down. According to the latest Mimecast State of Email Security 2019 report, we have witnessed an increase in phishing attacks globally, with 94% of organisations having experienced attacks in the last 12 months. There are various forms of phishing attacks but essentially all attacks attempt to gain sensitive, confidential information such as usernames, passwords, credit card information, network credentials and more, by posing as a legitimate individual or institution. These attacks are becoming more sophisticated in order to get around security solutions that are being put in place across most organisations. The most common form of phishing is not typically targeting specific individuals, but rather popular sites such as PayPal, which are cloned. Emails are then sent to many individuals instructing them to click on the malicious link to resolve account discrepancies in the hope of obtaining their credentials. With spear phishing, the fraudsters apply a more targeted approach to their craft. While this requires a little more effort as fraudsters need to acquire information about the targeted individuals, their task is made easier by using social media websites, such as LinkedIn, which has a wealth of information about the targeted individual. Whaling is a form of spear phishing where executives such as CEOs are targeted. Gaining access to a CEO’s email account allows criminals to target individuals in the organisation’s accounts department instructing them to release payments to the criminal’s account. www.intelligentcio.com Criminals are not only using email as an attack for phishing. Vishing is a form of phishing where criminals use the telephone to obtain personal information through social engineering. So what can organisations do to prevent these attacks? A holistic approach is required, one that includes security specific solutions, awareness training as well as changes to internal accounting controls. The first step is to implement security solutions that protect the company’s email environment. Managed service providers, such as Vox, offer a range of best of breed security solutions which are specifically designed to mitigate the risk of phishing attacks. While these solutions will significantly reduce the risk of such attacks, it is important to remember that implementing a security solution is not enough. Security solution providers are constantly innovating new features to meet the increasing sophistication of these attacks. This means that the solution requires constant management by certified security specialists who understand the relationship between product and skills and offer fully managed security services to ensure that the business remains protected. In addition to the security solution and managed services, organisations need to institute security awareness training for their staff. This educates employees to the dangers of phishing or other online scams. In the case of Vishing, security awareness training provides the only line of defence. Lastly, companies need to improve internal controls to mitigate the risk of whaling attacks as previously mentioned. In the event of a successful whaling attack, improved internal accounting controls ensure that payments are not made to the criminal’s account. INTELLIGENTCIO 25
