Utilising the Attack Surface: A New Method for Understanding the Threat Landscape

Enterprise Security Magazine | Wednesday, December 21, 2022

The threat landscape is constantly evolving as cybercriminals are getting more sophisticated and it seems new cyber threats are arising daily.

FREMONT, CA:Due to the increasing sophistication of cybercriminals and what appears to be a daily emergence of new cyber threats, the security landscape is continuously changing. Businesses can't change the threat landscape as cyber defenders. What management can do is speculate on how that environment might neutralise a threat, how it might gain entry, how it would navigate the infrastructure, and what damage it might cause. To create strategies to defend it, businesses must have a precise map of our attack surface.

Attack surface management (ASM), which includes the continuing process of asset discovery and risk classification, has received a lot of attention lately. A comprehensive map of attack points is provided by ASM solutions, which provide a constantly updated image of the entire technology infrastructure and the level of protection. This is especially crucial in light of how intricate modern IT stacks are.

Forrester estimates that 37 per cent of the world's cloud data centres are located in the Asia Pacific, with major corporations making inroads in countries including New Zealand, Malaysia, Thailand, and Indonesia. IDC estimates that 57 per cent of small and medium-sized enterprises (SMBs) in the Asia Pacific excluding Japan (APEJ) will increase their spending on cloud apps and services by 31 per cent from the previous year and that this trend will continue through the year 2025. This widespread use of cloud computing in the area inevitably attracts cybercriminals who use it as a springboard for their nefarious schemes.

Organisations evaluate themselves using ASM, which simulates the perspective of an adversary. This method pushes decision-makers to think about where attackers will strike first, which is useful for prioritising maintenance, upgrades, patching, tool acquisition, and policy implementation. They must concentrate on external attack surface management (EASM) in the multi-cloud and hybrid environments where regional organisations currently find themselves since this is where the conflict is currently taking place. Every application, port, server, website, cloud, and container must be examined, evaluated, and given a treatment priority ranking.

EASM which is natively connected enables cybersecurity teams to quickly and easily view the environment, including on-premises assets and remote cloud regions. Even if companies operate in a flexible business environment with shadow IT and a continuously shifting roster of technology partners, service providers, and other third parties–who come and go–analysts will be able to identify assets and their weaknesses before attackers do. Businesses need to move past the era of segregated asset management. Before, everything might have been departmentalized, from endpoints to development projects. But now they must acknowledge that this empowers dangerous actors. Security teams have a thorough, contextual awareness of what each asset does, how it is configured, and which department or person is in charge of it to formally manage configuration management databases (CMDBs).

Unfortunately, many EASM solutions do not provide a proper picture of assets, making assessment, prioritisation, and remediation difficult. Instead of enabling competent resources to innovate and contribute value, this gap results in manual processes that are prone to error and imprison them in boring workflows. This may result in decreased job satisfaction and worse rates of cybersecurity talent retention. This decline in security employees is a problem for the company given the geographical shortage of such skills.

Organisations must take into account the employee experience while creating a successful cybersecurity team, just as they must do in all other jobs. The complete external attack surface must be visible to analysts and threat researchers. New assets must automatically notify them. They must be able to monitor changes to the assets. Additionally, workloads must be able to be monitored anywhere they are used, including on public clouds. Nothing should evade the vigilant eye of the security team, including shadow IT, IoT sensors, devices, inactive IP addresses, and more.

When externally facing assets are no longer necessary for business operations, security and IT can collaborate to decommission or reconfigure them using the appropriate EASM solution. Regardless of location or ownership, the finest EASM platforms instantly link assets with business functions. These data points assist analysts in connecting the dots between an asset with an external facing and sensitive data or crucial systems (as an attacker would).

EASM is essential to the management of digital assets. It facilitates discovery by doing away with the need for extensive, time-consuming surveys of assets stored on-site, in the cloud, at the residences of employees, and in the buildings of partners, subsidiaries, and suppliers. Through the presentation of an attack path by attackers on the open Internet and how this might result in the loss of crucial data, proper EASM even enables organisations to gain control over asset attribution.

EASM makes it possible to conduct an ongoing risk analysis. Security teams are equipped with useful information by learning the when and how of each asset's production. Monitoring arrangements enhance this information (for example, unsanctioned open ports, unapproved services or expired or expiring SSL certificates). Additionally, EASM systems can help security professionals discover potential vulnerabilities through automated light scans and take appropriate action before malicious actors can do so by integrating with sources like the linked device search engine Shodan.

The combination of EASM and CMDB provides real-time visibility of the complete stack, which is what today's cybersecurity experts need most. A previously hidden or uncontrolled asset becomes apparent, and risk mitigation advances significantly. Automated processes identify vulnerabilities at a large scale, simplifying the once-complex task of thorough research and asset-by-asset patching.

Buying more cameras rarely fixes the problem. The old ones give grainy footage, nobody can pull up a feed from off site and the access control system sits in a corner with no connection to video at all. Add devices to that and you own more hardware and the same headaches. Start with the building instead. Where do people actually walk? Which rooms would hurt most if someone got into them? What cabling is already in the walls, and what is supposed to happen when an alarm goes off? Those answers decide what goes in and who runs it. A good design can account for every piece in it. Ask why a camera sits where it does, how much detail that camera needs to catch, who issues a credential and who takes it away, how the network carries all of it. Every answer should trace back to something seen on a walkthrough, not to a product the vendor likes selling. Power and the cabling already in the building shape the design as much as anything on a datasheet. Get that right and a security team knows what it is paying for, and stops paying for features that solve nothing. Long feature lists make the choice harder, not easier. IP cameras, video analytics, mobile credentials and biometric readers all do different jobs, and trading one for another is not an upgrade. A server room might genuinely need a fingerprint reader. A warehouse three states away probably cares more about whether anyone can see the feed at all, or how fast a credential dies when someone quits. What matters is not how much a provider stocks. It is whether they can shape the system around the way the place runs. “CTS walks the site first, assesses the risk, engineers a design around what it finds, then stays for integration, commissioning, training and everything after.” Retrofits test all of this. Some cameras and switches already up there still earn their keep. Others do not, and a provider should say in writing which are which and where compatibility gives out. The changeover needs planning too, because a building cannot go dark halfway through and nothing important should end up stranded on a platform the manufacturer has abandoned. New builds flip the problem. Power, conduit, door hardware and life-safety coordination all have to be settled while changing your mind still costs a phone call rather than a wall. Several sites complicate things further. A cloud-managed platform spares an administrator from logging into a dozen separate systems, though standardizing everything can iron out differences that ought to stay. One site opens at five in the morning. Another never closes. One has a guard on the door and another has nobody after six. Growth counts as well, because adding the eleventh building should not mean rebuilding how the first ten are run. Ask how far a provider’s architecture stretches before local control starts to disappear. Commissioning deserves as much attention as design and almost never gets it. Installed is not the same as working the way the drawings promised. Before anyone signs, test the devices, open the doors with real credentials, set the alarms off and confirm the integrations hold up. After that, the questions worth asking are simple. Can the provider spot a failing camera before anyone in the building notices? Does maintenance happen on a schedule or when something breaks? How quickly does somebody actually turn up? CTS walks the site first, assesses the risk, engineers a design around what it finds, then stays for integration, commissioning, training and everything after. New builds and retrofits both, including the thankless job of getting old infrastructure and third-party platforms to cooperate. CTS also supports cloud-managed video surveillance and access control across multiple locations while allowing site-specific permissions and procedures. Nothing changes hands until the devices and integrations have been checked against the approved design, and the customer’s own people have been trained to run the system. For anyone who values a rigorous design and a clean migration over a long datasheet, CTS is worth a look. ...Read more
Identity projects rarely collapse at the authentication screen. They drift earlier, when business owners answer different versions of the same access question, HR data leaves contractor status unresolved, application owners treat role definitions as local knowledge, and reviewers lack a common evidence trail.   For executives funding identity and access management (IAM) services, the purchase decision is no longer only about platform selection. The harder judgment is whether the service partner can convert scattered authority into usable specifications before the program enters configuration. A strong provider should reduce ambiguity at that point, not merely document it.  Large enterprises carry identity debt in places that rarely appear in a software demo. A directory may hold the login record while an HR system holds employment status, and privileged access often sits outside normal review habits. Customer identity programs add separate risk logic from employee access. Every exception forces coordination between security, compliance, HR and application teams, yet the people involved often speak from their own workflow rather than a shared control model.   This is where service quality becomes visible. The work must trace each identity to a source of truth and map roles against actual job behavior. Evidence also has to remain clean enough for audit review. Broad security coverage helps, but IAM buyers should press for the method behind role design and exception handling within access governance.  The early discovery phase deserves more scrutiny than it usually receives. Requirements gathering can become a slow relay of interviews and spreadsheet rework, especially when different stakeholders interpret plain questions in different ways. A delayed requirements phase does not simply move a project date. It widens the period in which access risk remains unresolved and pushes skilled analysts into chase-work that adds little judgment.   Better service models treat requirements as a controlled workflow. They give respondents context, track completion while the work is still live, and convert answers into documents that implementation teams can use without rebuilding the logic by hand. The point is not speed alone. Faster documentation only matters when it preserves the nuance needed for provisioning rules and review cycles.  Vendor selection should also test independence from a single technology path. Many IAM engagements need alignment across established platforms rather than loyalty to one stack, particularly when enterprises already run Microsoft, Okta, CyberArk, SailPoint or related identity tools. Managed service coverage can support teams that lack enough internal bandwidth, but it should not blur accountability for design decisions. A stronger partner understands where configuration ends, and governance begins. It can support an enterprise from source-of-truth analysis through access policy design while producing artifacts that survive scrutiny after go-live.  For buyers who need this discipline before implementation begins,  CTI  is the premier choice. It combines identity consulting experience with work across major IAM and IGA platforms and has built Identity CoAnalyst to address the requirements gap directly. The platform uses practitioner-built questionnaires, stakeholder tracking, guided response collection and automated document generation to shorten discovery while improving the quality of inputs. This fit matters for executives who need identity programs to start from accurate roles, traceable requirements, cleaner handoffs and fewer late-cycle corrections rather than another extended spreadsheet exercise.  ...Read more
Security investments no longer fail due to a lack of technology or funding. It fails when systems evolve in isolation, decision-making fragments across locations and execution drifts from long-term intent. Large organizations operate across distributed environments where inconsistent standards, limited visibility and misalignment between tools and workflows erode performance. The impact builds gradually, with rising costs and declining effectiveness. A more disciplined approach treats security as a continuous program rather than a sequence of deployments. Systems must be designed across their full lifecycle, from architecture through service, upgrades and compliance alignment. Without continuity, even well-funded environments accumulate inefficiencies as technologies age, integrations weaken and oversight turns reactive. Long-term planning aligned with business priorities keeps security predictable, measurable and tied to capital strategy. Consistency across locations is equally critical. Enterprises at scale cannot operate with fragmented standards across sites, vendors or teams. A unified framework governing technology, implementation and performance creates a stable foundation. It enables leadership to maintain visibility across the full security footprint while ensuring regulatory and operational alignment. Standardization does not limit flexibility. It enables confident, informed decisions across the organization. Centralized governance must coexist with local responsiveness. Security conditions vary by site, risk profile and operational rhythm. Local teams need authority to act in real time, yet within clearly defined parameters that preserve enterprise alignment. This balance determines whether a program can adapt without losing control. Organizations that achieve it maintain both agility and discipline. "Security is Not a Collection of Systems. It is a Lifecycle Strategy That Aligns Technology, Operations and Governance To Deliver Consistent Performance Across The Enterprise." Another common gap lies in the belief that more technology or personnel reduces risk. Effectiveness depends on integration. Disconnected systems, poorly aligned tools and workflows that do not reflect real operations create friction instead of clarity. Security must be intuitive for operators, connected across systems and supported by processes that sustain performance over time. When these elements align, organizations gain actionable intelligence and consistent outcomes. High-demand environments make this alignment essential. Transportation hubs, utilities and large venues must sustain operational flow while managing complex threat exposure. Security cannot disrupt throughput or user experience. Layered design, coordinated visibility and precise execution allow protection to operate in the background while supporting core operations. Within this landscape, Allied Universal Technology Services (AUTS) operates with a lifecycle-driven model built on integration and operational discipline. It aligns technology, personnel and intelligence from initial design through long-term optimization, ensuring systems evolve with business needs. Its structured approach enables consistent standards across locations while empowering local teams to respond within defined frameworks. By unifying fragmented systems into connected environments and supporting them through continuous service, AUTS reduces operational silos and strengthens visibility across the enterprise. This approach delivers security programs that remain stable, scalable and aligned with business priorities over time. For organizations managing complex, distributed environments, it represents a dependable model for sustained performance and control. ...Read more
Cyber risk advisory purchasing often begins after an urgent trigger, such as a cyber-insurance renewal, a board inquiry, an acquisition review, or a regulatory deadline. The danger is paying for a technical assessment that produces findings but leaves management without a workable path. Executives need advice that can translate between exposure, cost, staffing limits and control work without flattening the problem into a tool recommendation. That is where many advisory selections break down. The proposal looks technically sound, but the engagement never proves how the work will fit the buyer’s deadlines, authority lines, staffing limits and decision habits. A useful advisory partner begins before any scan or framework mapping. It must identify who owns the decision, what risk event is driving action, how mature the environment is, and where existing staff can realistically carry out the work. That early discipline matters because many engagements are misframed at intake. Insurance questionnaires can point to control gaps that are really staffing gaps. A narrow policy update can hide weak governance. A penetration test can expose executive communication issues before it exposes systems. M&A diligence can turn a cyber-review into a timetable problem. Buyers should be wary of advice that moves too quickly from symptoms to controls without testing the business context behind the request. Technical depth still matters, but it has to show up as judgment under constraints. Advisory work should define scope across business units, set testing windows that do not disrupt critical work, protect sensitive findings and decide how findings should move between executives and project teams with different authority levels. Reports should separate fix-now exposure from longer program work and tie recommendations to named owners and realistic timing. Good findings are not enough. Leadership needs to know which risks can be accepted for a limited period, which weaknesses block a transaction, which issues can wait for a budget cycle, and which work requires outside depth. "Cibernetica Group Focuses on Helping Leadership Teams Make Informed Cybersecurity Decisions that Support Broader Business Goals." Stronger advisory engagements also avoid the false handoff between strategy and execution. Some buyers have an internal security office that can take a design and run with it. Others need help moving from board discussion to architecture choices, policy cleanup, remediation oversight and day-two support. The same advisor does not have to perform every task, but it should know where strategy becomes project risk and where project work starts to change risk posture. Capacity is part of the buying decision. Advice that assumes a fully staffed security team can leave smaller companies with a polished plan and no practical way to carry it out. For buyers seeking a premier choice, Cibernetica Group's advisory model begins by understanding business drivers, organizational maturity, risk exposure, and stakeholder priorities before recommending a solution. The company works with clients across the cybersecurity lifecycle, helping them assess risks, develop strategies, align security initiatives with business objectives, and, when needed, support implementation and ongoing operational requirements. Its approach is designed to avoid one-size-fits-all recommendations, instead tailoring guidance to each organization's specific needs and circumstances. Whether organizations are responding to compliance requirements, insurance considerations, growth initiatives, or M&A activity, Cibernetica Group focuses on helping leadership teams make informed cybersecurity decisions that support broader business goals. ...Read more
