BAE Systems has been awarded official approval under the Bank of England's CBEST security testing framework for helping banks to boost cyber defences.
The CBEST approval means that BAE has been through a testing process designed and administered by the Bank and England and the UK financial authorities.
It will see the firm use its intelligence-led penetration testing, based on data gathered from its network on the tools and techniques used by hackers to attack firms, to help banks discover if and where weaknesses within their networks lie.
This intelligence can be used to simulate attacks and gain insight into how networks can be hacked and understand the consequences to the business should an attack be successful.
There is a list of companies that, like BAE, have the official seal of approval.
BAE already works closely with the UK banking industry, and said that the accreditation is an acknowledgement of the firm's strong threat intelligence and penetration services, two areas which are key to protecting the modern enterprise regardless of its vertical industry.
Scott McVicar, EMEA managing director for commercial solutions at BAE Systems Applied Intelligence said it was a vital the banking sector adequately tested its defences to be prepared for any major cyber attacks.
"Intelligence-led penetration testing has to be based on rich contextualised intelligence which informs and guides how the test should be conducted, what attack methods should be simulated and where testers should focus their resources," he said.
"This method of testing provides a more structured and effective approach for companies to mitigate their cyber risk and understand the real effectiveness of the key technical security controls they have in place."
The Bank of England explained that CBEST throws a combination of attacks and attack methods at the financial services sector to create an impression of their ability to withstand potential and live attacks.
The security of the banking sector is a key concern for the industry, with numerous tests taking place over the past few years to assess the preparedness of organisations to defend and respond to high-profile cyber attacks.
