Given how lucrative and vital finance companies are to the UK economy, it’s no surprise that cyber criminals are trying their luck at infiltrating these organisations, stealing sensitive information, and causing havoc. In fact, the Financial Conduct Authority has revealed that the number of declared cyber-incidents in the UK finance sector has risen by more than 1000% since last year.
The evidence is rife too – earlier this year, Metro Bank became another victim that was added to the list of cyber-attacks, after hackers were able to intercept a telecommunications vulnerability, affecting on a few customers however. Not as lucky was Tesco Bank, which was subjected to a £16.4 million fine when a staggering £2.26 million was stolen from customers’ personal current accounts.
Despite such high-profile attacks being reported within the financial sector, businesses are still failing to implement robust cybersecurity policies. And, amid today’s advanced threat landscape, it is usually a case of ‘when’ and not ‘if’ a firm is breached. Many financial firms are still just trying to get the basics right, have old IT systems in place and do not carry out regular cyber-assessments.
What’s the problem?
It’s evident the industry needs to boost and improve its defence against malicious attackers, but first, it’s important to pinpoint where the issues are coming from. From the BeyondTrust 2019 Privileged Access Threat Report, 58% of organisations believe it is likely they have suffered a breach due to vendor access, and 64% say employees were a cause of the breaches – of which financial organisations are included. Indeed, most organisations in and out of the financial industry are having a difficult time managing privileged insiders and third-party vendors, in fact, almost half still use manual processes to control privileged identities, which simply isn’t scalable.
What’s the solution?
In light of these findings, employee error needs to be minimised, and should it happen, the ramifications need to be promptly dealt with effectively.
The weakest link in an organisation, often starts with employees. Usually ranging from their poor password hygiene, to being targeted by phishing emails. And, unfortunately, by giving employees administrator rights, this puts systems and data in the firing line for hackers. So, it’s paramount to tackle this issue at its root.
Indeed, productivity issues arise when limiting user rights–IT help desks can often be inundated with requests to grant access to basic systems or files. As such, the balance between security and productivity, specifically within a fast-paced, high growth environment like the finance sector, always seems to be a trade-off.
So, how can this be remedied? By removing unnecessary admin rights and giving users just enough access to do their jobs productively, organisations can significantly reduce the attack surface. To achieve this, Privileged Access Management (PAM) can be implemented. Three features of an effective PAM solution include:
- Lock down and control credentials: Find, manage, and monitor privileged accounts/assets, and automate privileged password and session management.
- Remove excessive end-user privileges: Control and monitor privileged activity on Windows, Mac, Unix, Linux, and network devices, remove excessive privileges without impacting productivity, and enforce granular application control.
- Protect internal and vendor remote access: Secure, manage, and audit remote access from third-party vendors and internal employees with privileges, such as the service desk.
When organisations have fully integrated PAM tools, they are more confident to identify threats from employees with privileged access. With control and visibility over their entire environment, organisations can significantly reduce the likelihood that they become a victim of a breach, while allowing their employees to remain fulfilled and productive at work.
