Data breaches and security threats are a top concern for any organization; the resulting physical damages, financial ramifications and loss of business can range from disruptive to catastrophic depending on the severity of the incident. That makes a strong security posture critical.
However, the traditional practice of maintaining separate physical and cybersecurity operations leaves a gap that represents a significant risk. Criminals may either aim to enter restricted areas to cause physical damage, or access internal systems via cyber-attacks to disable systems or steal data. In a worst-case scenario, they may exploit vulnerabilities in both physical systems and networks to attack on multiple fronts.
As The Cybersecurity and Infrastructure Security Agency (CISA) points out, a growing network of interconnected systems and devices via the Internet of Things (IoT) and Industrial Internet of Things (IIoT) has created an overlap in physical systems and cybersecurity strategies. What this means is that where there were once clear distinctions between the roles of physical security vs. cybersecurity, that line is now blurred.
The attack surface has also become even more complex with the increasing adoption of remote working, which can turn an organization’s physical perimeter into a virtual perimeter, leaving potential gaps in the network that hackers can exploit.
According to CISA, when security personnel operate in silos, the organization lacks a holistic view of security threats across the organization, which can create larger vulnerability gaps, increased redundancies across teams and drain security budgets over time.
This is where security convergence comes in. A converged security strategy is based on shared threat information and collaboration between both teams to improve security posturing.
In this article, we will look at the importance and benefits of security convergence, and outline best practices for building and operating a converged security strategy. You will also learn what Security as a Service is, and how this plays an important role in simplifying security operations in today’s vulnerability landscape.
Physical security and cybersecurity have traditionally been treated as different roles; however, the rise of interconnected systems is driving the need for these previously siloed teams and systems to work together.
Security convergence (or converged security) is the approach of integrating cybersecurity and information technology strategies with physical security measures to increase awareness and strengthen protection of facilities, people and data in a holistic way.
In other words, converged security combines the efforts of safeguarding physical assets, such as by limiting access, installing video surveillance and using intrusion detection, and protecting digital assets like computers, networks and applications.
As more physical systems now rely on Internet connectivity and local networks to operate, with IoT integrations and cloud-based systems among the top 2023 security trends, security convergence is more important than ever. The changes in the way businesses work, together with greater use of public cloud, highly connected supply chains and use of cyber-physical systems have exposed new and challenging attack surfaces, which leaves organizations more vulnerable to attack. Going a step beyond traditional approaches to security monitoring, detection and response can help manage this wider set of risks.
One of the key pillars of security convergence is that both the physical security and cyber security teams within organizations share an objective — to secure critical assets. Although the two teams approach this goal from different perspectives, organizations can achieve the maximum level of protection by converging teams and systems.
However, it’s important to note that the goal of security convergence is not to combine two security departments into one. Instead, converged security should create a policy that combines the efforts of both departments to ensure they are prepared to work in a unified way to prevent and manage threats and provide the organization with a consistently comprehensive view of its overall security.
Successfully implementing security convergence in an organization starts with a detailed plan that takes into account all the systems, teams and threat responses already in place, and defining new goals that combine all those efforts. CISA recommends three integrated phases to security convergence that can overcome those barriers:
Despite the strong case for convergence, a recent study found that not all organizations are prepared to make this organizational adjustment. The greatest difficulties in rolling out converged security strategies typically center around:
However, the benefits of rolling out converged security can far outweigh the initial challenges, especially with the proper planning and execution.
It’s important to set strategic goals for security convergence so that all stakeholders, including senior executives, buy into change. Key goals include:
Information sharing is also critical to a successful convergence strategy. As proactivity and efficiency are core goals of security convergence, many organizations leverage the immense amount of data produced by their IoT and cloud-based solutions for actionable intelligence.
Smart access control systems, for example, provide security teams with comprehensive data on access to campuses, buildings, restricted areas and infrastructure, plus insights into movements within an area that can help security teams detect unauthorized entry so they can respond to physical threats. The data from access control systems also enables teams to identify unusual patterns of behavior, which may represent potential threats that require a proactive response.
Cybersecurity teams also receive regular threat updates as well as recording data on attacks or hacking attempts. Bringing the two sets of data together gives the converged teams a 360-degree view of threats to the business, eliminates gaps in situational awareness and provides a holistic picture of security threats at every level.
To successfully implement a physical and IT security convergence strategy, it’s essential to follow recommended best practices:
There’s a reason cloud-based solution adoption and security convergence are both rising trends across industries. Convergence can progress more smoothly if security teams use the cloud for managing both cyber and physical systems.
Cloud enablement can also support Security as a Service (SECaaS), which can help to accelerate security convergence by managing both physical and cybersecurity through third-party Security as a Service providers.
Security as a Service in cloud computing is an outsourced service that enables internal teams to use advanced security tools through a single dashboard while the service provider manages the systems.
Security as a Service or SECaaS is an umbrella term that incorporates other more specific services, including Physical Security as a Service (PSaaS) and Endpoint Security as a Service.
PSaaS providers take responsibility for day-to-day management and updating of security hardware such as video cameras, sensors, electronic door locks and access control systems, while internal teams can manage security functions such as user access levels, issuing guest passes or accessing security data and video footage.
Security as a Service providers can offer many different categories of service, including network security, vulnerability testing, data loss prevention, continuous monitoring and identity management, among others.
Adopting SECaaS provides internal teams with a wide range of benefits. They gain access to the services of highly skilled security professionals using the latest security tools. The services are available on demand so that internal teams can add services or scale up resources without delay or disruption. Using SECaaS for day-to-day security management frees internal resources, allowing teams to focus on strategic tasks.
Because SECaaS covers both physical and digital security functions, the service can help support a security convergence strategy by providing continuous monitoring and complete visibility of any security events in a building or on the network.
Most Security as a Service providers operate on a subscription model, with varying tiers of service depending on the size or security needs of a business. The benefit here is that when needs change, it’s fairly simple to add or remove services to a SECaaS or PSaaS subscription, so you only pay for what you use.
When selecting a Security as a Service provider, It’s important to ask questions and make sure they provide the services your business needs. Some things to compare include:
It’s no longer a case of physical security vs. cybersecurity, but converging the two to form a future-proof security strategy. A converged security strategy can provide your business with a number of important benefits by strengthening security posture and eliminating any gaps in security coverage that attackers could exploit. Converged security is particularly important if your organizational systems feature a number of vulnerable areas where cyber and physical systems are interdependent.
While there may be initial organizational or resource barriers to convergence, it’s important to remember that professional services are available that can work with internal teams to provide essential services and support so that teams can focus on convergence.
