FEATURE : NETWORK SECURITY
Adam Gordon , Country Manager
ANZ at Varonis , explains the most common causes of insider data breaches , the impact of remote working and key ways organisations can mitigate these risks .
In movies , nefarious corporate insiders are the hoodie-wearing outcasts that avoid conversation and keep to themselves . The reality is different . Chances are , you wouldn ’ t be able to pick out an insider bent on harming your organization .
Many organizations don ’ t consider the risk that these parties present , but there ’ s strong reason to – Verizon ’ s 2020 Data Breach Investigations Report revealed that 30 % of all breaches last year involved internal actors .
Data represents their most important and valuable asset for many organizations , but too few organizations keep their data tightly controlled . Instead , data is often open and accessible to all employees within the organization , where it can not only be accessed but copied , moved , altered , deleted – or simply emailed from person to person – and even outside the company .
Ideally , access to data in any organization should be restricted to only those who need it . This approach reduces the chances of that data being exfiltrated , corrupted or encrypted if users ’ access protections are compromised , typically through a successful phishing exercise .
