Legacy network security proves costly: Palo Alto

Legacy network security proves costly: Palo Alto

Advanced threats can’t be effectively addressed using a ‘set it and forget it’ approach

Outdated IT network security systems and a lack of collaboration are contributing to unnecessary and costly manual incident responses to advanced threats.

Palo Alto Networks systems engineering manager A/NZ Gavin Coulthard said one of the most consistently neglected costs of any security product is neither the price nor maintenance, but the time and talent required from security experts.

“Cybersecurity architects and managers need to recognise the dramatically diminished effectiveness of legacy network security solutions that continue to rely on methods and technologies designed for the threats of yesterday,” he said.

“Advanced cyber threats simply can’t be effectively addressed using a ‘set it and forget it’ approach to security.

“Worse still, the vast majority of security products focused on advanced threats stop at detecting a threat, which kicks off an incident response phase.

Coulthard said modern IT incident response required a set of highly technical skills including advanced traffic analysis, memory forensics and reverse engineering of malware - highly technical disciplines.

“An enterprise would be lucky to have just one of these experts on staff,” he said.

“The fundamental problem is that advanced threats are not sufficiently rare.”

He said the IT security industry and organisations needed to grow to a place where incident response is reserved for the truly exceptional threats, not those that simply slide through outdated security models invented a generation ago.

In order for this to happen the industry needs better and faster sharing of threat intelligence to create a shared level of protection.

It also need a more automated approach to investigate threat events, avoiding deep-dive technical analysis.

However, Coulthard said, understandably, many organisations were reluctant to share what they found about advanced cyber threats on their networks.

“Some may see knowing how to combat an advanced threat as a competitive advantage while others may see sharing the information as drawing unwanted attention to their network’s vulnerabilities,” he said.

“The important thing to remember is this: until there is a more collaborative approach to threat identification and mitigation, combined with an automated approach to investigating threat events, Australian organisations will continue to suffer from the adverse effects of advanced cyber threats.

“It’s only when these two elements come together in a more mature approach that we will be able to minimise the amount of human intervention required and thereby reduce costs.”

OKI recently hosted its ChannelOne dealer forum for its executive series channel partners to get together and learn about the company's new high-performance ES8400 A3 multifunction series printers. After a welcome and business overview from OKI Data Australia managing director, Dennie Kawahara, delegates were given a comprehensive overview of the new product, as well as an update on the latest marketing initiatives and software solutions, before being treated to live demos and a product showcase. Partners were also given a preview of OKI’s upcoming A3 digital LED white toner printer. With more than 60 delegates attending from all over the country, the day concluded with dinner at Casa Ristorante Italiano in Sydney and several delegates also participated in a friendly game of golf the following morning.
