Tag: endpoint detection and response

Trust in the Banking, Financial Services, and Insurance (BFSI) industry is critical – and this amplifies the value of stolen data and fuels the motivation of malicious actors. Ransomware attacks continue to escalate, underscoring the need for fortified backup, encryption, and intrusion prevention systems. Similarly, phishing schemes have become increasingly sophisticated, placing a burden on BFSI cyber teams to educate employees, inform customers, deploy multifactor authentication, and implement fraud detection systems. While BFSI organisations work to fortify their defences, intruders continually find new avenues for profit – cyber protection is a high-stakes game of technological cat and mouse!

Some of these challenges inherent to the industry include the rise of cryptojacking – the unauthorised use of a BFSI company’s extensive computational resources for cryptocurrency mining.

Building Trust Amidst Expanding Threat Landscape

BFSI organisations face increasing complexity in their IT landscapes. Amidst initiatives like robo-advisory, point-of-sale lending, and personalised engagements – often facilitated by cloud-based fintech providers – they encounter new intricacies. As guest access extends to bank branches and IoT devices proliferate in public settings, vulnerabilities can emerge unexpectedly. Threats may arise from diverse origins, including misconfigured ATMs, unattended security cameras, or even asset trackers. Ensuring security and maintaining customer trust requires BFSI organisations to deploy automated and intelligent security systems to respond to emerging new threats. 

Ecosystm research finds that nearly 70% of BFSI organisations have the intention of adopting AI and automation for security operations, over the next two years. But the reality is that adoption is still fairly nascent. Their top cyber focus areas remain data security, risk and compliance management, and application security.

Addressing Alert Fatigue and Control Challenges

According to Ecosystm research, 50% of BFSI organisations use more than 50 security tools to secure their infrastructure – and these are only the known tools. Cyber leaders are not only challenged with finding, assessing, and deploying the right tools, they are also challenged with managing them. Management challenges include a lack of centralised control across assets and applications and handling a high volume of security events and false positives.

Software updates and patches within the IT environment are crucial for security operations to identify and address potential vulnerabilities. Management of the IT environment should be paired with greater automation – event correlation, patching, and access management can all be improved through reduced manual processes.

Security operations teams must contend with the thousands of alerts that they receive each day. As a result, security analysts suffer from alert fatigue and struggle to recognise critical issues and novel threats. There is an urgency to deploy solutions that can help to reduce noise. For many organisations, an AI-augmented security team could de-prioritise 90% of alerts and focus on genuine risks. 

Taken a step further, tools like AIOps can not only prioritise alerts but also respond to them. Directing issues to the appropriate people, recommending actions that can be taken by operators directly in a collaboration tool, and rules-based workflows performed automatically are already possible. Additionally, by evaluating past failures and successes, AIOps can learn over time which events are likely to become critical and how to respond to them. This brings us closer to the dream of NoOps, where security operations are completely automated. 

Threat Intelligence and Visibility for a Proactive Cyber Approach

New forms of ransomware, phishing schemes, and unidentified vulnerabilities in cloud are emerging to exploit the growing attack surface of financial services organisations. Security operations teams in the BFSI sector spend most of their resources dealing with incoming alerts, leaving them with little time to proactively investigate new threats. It is evident that organisations require a partner that has the scale to maintain a data lake of threats identified by a broad range of customers even within the same industry. For greater predictive capabilities, threat intelligence should be based on research carried out on the dark web to improve situational awareness. These insights can help security operations teams to prepare for future attacks. Regular reporting to keep CIOs and CISOs informed of the changing threat landscape can also ease the mind of executives.

To ensure services can be delivered securely, BFSI organisations require additional visibility of traffic on their networks. The ability to not only inspect traffic as it passes through the firewall but to see activity within the network is critical in these increasingly complex environments. Network traffic anomaly detection uses machine learning to recognise typical traffic patterns and generates alerts for abnormal activity, such as privilege escalation or container escape. The growing acceptance of BYOD has also made device visibility more complex. By employing AI and adopting a zero-trust approach, devices can be profiled and granted appropriate access automatically. Network operators gain visibility of unknown devices and can easily enforce policies on a segmented network.

Intelligent Cyber Strategies

Here is what BFSI CISOs should prioritise to build a cyber resilient organisation.

Automation. The volume of incoming threats has grown beyond the capability of human operators to investigate manually. Increase the level of automation in your SOC to minimise the routine burden on the security operations team and allow them to focus on high-risk threats. 

Cyberattack simulation exercises. Many security teams are too busy dealing with day-to-day operations to perform simulation exercises. However, they are a vital component of response planning. Organisation-wide exercises – that include security, IT operations, and communications teams – should be conducted regularly. 

An AIOps topology map. Identify where you have reliable data sources that could be analysed by AIOps. Then select a domain by assessing the present level of observability and automation, IT skills gap, frequency of threats, and business criticality. As you add additional domains and the system learns, the value you realise from AIOps will grow. 

A trusted intelligence partner. Extend your security operations team by working with a partner that can provide threat intelligence unattainable to most individual organisations. Threat intelligence providers can pool insights gathered from a diversity of client engagements and dedicated researchers. By leveraging the experience of a partner, BFSI organisations can better plan for how they will respond to inevitable breaches. 

Conclusion

5/5 (2) Organisations across the globe, are facing disruption on a scale never seen before, and are urgently seeking ways of remaining viable. Predictably, cybersecurity is a secondary concern and is often handled reactively. To make matters worse, a chronic cybersecurity skills shortage is being made much more severe by the crisis.

Remote working has reached unprecedented levels as organisations try hard to keep going. This is massively expanding the attack surface for cyber criminals, weakening security and leading to a cybercrime pandemic. Hacking activity and phishing, inspired by the COVID-19 crisis, are growing rapidly. Containing and suppressing this cybercrime pandemic is proving to be almost impossible.

Remote working intensifies known threats posed by phishing and ransomware. More alarming are the distinctive cybersecurity vulnerabilities associated with home working including reliance on home Wi-Fi, increased use of unpatched VPNs and devices, and the exponential growth of network access points. These vulnerabilities increase the likelihood of a breach enormously.

Corporate IT is in a very challenging position. It needs to ensure that organisations can operate in a way that they have never operated before, while ensuring that their assets are secure – a very difficult, if not an impossible task for which there is no precedent.

Some important cybersecurity considerations, during and after the COVID-19 pandemic include:

Re-enforce Basic Cyber Hygiene

As massive numbers of people work from home, basic cyber hygiene becomes more critical than ever before. Organisations must maintain awareness of security threats among employees, ensure security policies are being followed and be certain that corporate software is being updated and patched on time. With a dispersed workforce, these basic practices are more challenging, and training becomes more critical. Phishing attacks are often the primary attack vector for malicious actors, so employees must be able to identify these attacks. They increasingly exploit shortages of goods such as protective equipment and sometimes claim to offer official information relating to COVID-19.

Remote employees often access sensitive business data through home Wi-Fi networks that will not have the same security controls – such as firewalls – that are used in offices. There is more connectivity from remote locations, which requires greater focus on data privacy, and hunting for intrusions from a much larger number of entry points.

Place More Focus on Endpoint Security

The unprecedented switch to remote working is radically increasing the number of vulnerable endpoints. Given that endpoints are located at a distance from corporate premises, it is frequently difficult for IT departments to configure endpoint systems and install necessary security software.

It is vital to assess the security posture of all endpoints connecting to the corporate network. This practice enables an organisation to determine whether or not an endpoint requesting to access internal resources meets security policy requirements. It requires the ability to monitor and enforce policy across all devices, while making onboarding and offboarding seamless.

It is essential that endpoint solutions can be rapidly deployed for remote workers, as needed on both personal and corporate devices. Devices used for remote work need much more than the basic antivirus and antispyware protection. Multi-factor authentication (MFA) and on-board endpoint detection and response (EDR) capabilities are crucial.
