James Todd, SecOps director at KPMG, describes his position as a merging of SecOps, safety structure, and cloud safety. It is a very attention-grabbing crossing level with regard to automation.
“It’s at that intersection of the cloud environment, being very much aligned to deploying everything as code,” says Todd. “A lot of automation is a big part of that. Being able to take dynamic action within a cloud environment is much easier and well-versed than within a traditional data centre or on-premises environment. The controls available to us are much more dynamic.
“That doesn’t preclude us from being able to do things within security controls on the endpoint or within on-premises data centres, but it’s a different approach.”
Research from the Enterprise Strategy Group in October discovered that just about half (46%) of SOC groups are automating safety operations processes ‘extensively.’ Alongside this, greater than half (52%) of respondents agreed with the assertion that safety operations had been harder now than two years in the past.
It is no surprise, due to this fact, that getting automation to work inside the safety operations centre (SOC) is a significant level of emphasis for KPMG. One be aware from the skilled companies agency final yr insists that automation can have a ‘significant and positive impact on the effectiveness of CISOs and their teams.’ Another, a month later, put automation, alongside upskilling and variety, as one of many three key approaches to bridging the cybersecurity abilities hole.
Todd’s unit offers SecOps consultancy and operations for monetary companies organisations. There are two major forms of consumer. One is an organization that has little in the best way of safety operations inside their organisation; they’re both an organisation which has grown in measurement and desires a extra formal course of. Alternately, they’re extra established and wish to tread the road between ‘dynamic change within their environment plus continuous change in the threat landscape,’ as Todd places it. The second are organisations that must go to the subsequent degree – and that is the place automation can are available in.
“Once that established playbook or workbook has been created in relation to a particular threat, or a particular way that incidents are handled, we look then to introduce automated processes that reduce the repetitive task element within security operations initially, and then move to the higher end of automation and introduce some level of autonomy,” says Todd. “So the SOC can react to threats in as near real-time as possible.”
Getting the steadiness proper between automated tooling and human sources is a longstanding head-scratcher for executives. Writing in Security Week in November, Marc Solomon sums the issue up succinctly: ‘using automation to make your people more efficient, and using your people to make automation more effective.’
The easiest a part of automation, Todd explains, is the robotic course of automation (RPA) component, which frees time for the SOC analyst to work on incident dealing with, menace looking, and different very important duties. The subsequent step is to maneuver in the direction of applied sciences resembling machine studying to result in extra clever decision-making – or machine-led decision-making. “The platform builds trust in those actions and understands the impact of a particular action playing out,” says Todd.
“If I see a particular indicator file within my environment that is correlated with threat intelligence, and I know the asset that has been targeted, that asset’s security posture and also its susceptibility to the attack that’s being aimed at it, I can then use machine learning to inform a number of decisions that I can take,” he provides. “All the way through from quarantining that particular asset, limiting its movement, playing out particular activities that allow us to gain some further intelligence.”
Todd references the influential MITRE ATT&CK matrix first launched in 2015, which catalogues a whole lot of techniques adversaries use throughout enterprise working programs. While ATT&CK is not specified by a specific linear order, the primary class, ‘initial access’, is the purpose the place an attacker will get a foothold in an organisation’s atmosphere. This is the place Todd desires his group to be.
“The optimal goal for us is to get to a point where we’re taking action or intervening at the point that the attack is first observed within the cyber kill chain,” says Todd. “Really being slick around being able to observe and take action around the first point that an attacker tries to enter an environment.”
Todd, who’s talking on the Cyber Security & Cloud Expo Global, in London on December 1-2 round cloud safety, provides that probably the most generally used type of machine studying inside cyber defences is anomaly detection. Right now, that’s the place automation is more likely to keep.
“I think [where] the human element comes into it is that machine learning is good at spotting outliers and anomalies,” says Todd. “The decision making, certainly for the moment, will reside within the analyst, within the SOC.
“Those analysts [will] be codifying and transferring their well-proven, well-exercised playbooks, or converting those playbooks into an automated approach,” provides Todd. “But I don’t think that we’re quite yet at the time where we’ve got full autonomy on decision-making.”
