Cybersecurity - An Integral Aspect of a Successful Enterprise

Enterprise Security Magazine | Monday, January 28, 2019

IT security is an approach to harden the perimeter of the data center to prevent the invasion of external factors; while providing access to users to fulfill the intended purpose of the software.

Cybersecurity has become an integral part of application building because protecting privacy is preserving human rights and freedom, especially to the application that connect to the internet or to each other. Cybersecurity should be implemented from the early stages of the software life cycle development process. The whole topic of security actually encompasses and embraces aspects like privacy, safety, protection, and defense. Some key aspects designers concentrate to ensure security in every level are

Security framework:

Designers will typically try to protect their customer assets against threats by implementing security measures. The main assets in a system that are vulnerable to attacks are data, code, device identities and keys. Developers identify their “customer assets” and categorize them into these categories at the semiconductor level. The key customer assets are physical or logical objects that have to be protected and also firmware that a user loads onto a device, data transmitted over a network or material stored on a device.

Risk assessment and security discovery:

Two steps for risk assessment and security are

•Qualitative risk assessment to identify vulnerabilities, potential threats, the probability of threat and measures required in case of a threat.

•Quantitative risk assessment to identify loss in case a threat is realized, such as mapping a dollar amount to a specific risk.

Attack surfaces:

The attacker poses three main types of threats

• The network: An attacker present at the location or in close proximity may use communication channel either wired or wireless to access devices to attack.

•The Board: The board threats target a printed circuit board (PCB) access and use any wired interface on the chip to gain access to sensitive data.

•The chip: The chip threat is a physical attack that infiltrates device access to perform integrated circuit decapsulation and deprocessing to gain access to the internal layers and elements of the chip

Network attacks

With a massive acceptance of IoT connected devices, network attacks are becoming more common. Networks topology provides numerous attack paths and a growing potential to identify an exposure point through which an attacker can reach the target asset. An attack from the network is less obvious, so the attacker has some level of anonymity over a physical attack. This is attributed to a number of aspects related to the fundamental nature of communication networks.

The most common types include:

• Tapping: Tapping is an act of checking the network at various points with tools that can eavesdrop, intercept, replay and impersonate anything transmitted over the network. In general, measures that can achieve confidentiality, integrity, and authenticity of the transmitted assets or commands need to be implemented.

 • Man-in-the-middle (MITM): There is an attack in which the attacker’s gains access of assets without being detected to relay and possibly alter the communication between two entities who think they are communicating directly with each other. An attacker can insert himself as a MITM into a network using unencrypted Wi-Fi access point within range.

• Distributed Denial of service (DDoS): This attack blocks the availability and accessibility of a resource by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. A distributed DoS attack is a synchronized attack originating from multiple sources, thus making it harder to detect and block the origin or source of the attack.

• Malware: Malware is malicious software intentionally designed to cause damage to a computer, server, client, or computer network successfully delivered to a point with network access. On reaching the targeted point, the software may potentially attack that point either passively to monitor activity or actively to alter its behavior.

Exposure points: Points in a system where there could be a risk of attack or a way of entry for the attackers to gain access is called Exposure points. The three possibilities of exposure points are:

 • Storage:  The attackers can target keys, data or code potentially exposed at rest in external or internal chip memory.

• Run time: The attackers can target Keys, data or codes which are potentially exposed during run-time operations of the application.

• Transfer: The attackers can target data or code potentially exposed during transfer from/to a remote location. The transfer could be eavesdropped, intercepted or impersonated by the attacker.

Consequences of poor security

Poor security at a business place can lead to disastrous results like electronic theft, corporate espionage, loss of access, and legal liability for the business and its suppliers also. Addressing safety and security issues throughout the communications and electronic transactions will help to avoid problems that can affect a company and its stakeholders.

Outdoor properties can change faster than a surveillance plan. Fences shift, gates get left open, materials move and work schedules change. A system built around static rules or queued alerts can become less useful precisely as a site changes. For executives buying remote video monitoring, the central question is not whether video exists. It is whether someone can interpret what is happening while there is still time to intervene. The cost of delayed judgment is greatest where equipment is exposed and boundaries are temporary. Response speed is inseparable from how video is reviewed. An alert delivered after playback sits in a queue may document an event but miss the chance to interrupt it. Outdoor sites also produce ambiguous activity. Legitimate crews may arrive outside normal hours, pedestrians may pass nearby, animals may enter view or an intruder may test a fence. Live monitoring earns its cost when reviewers can distinguish routine movement from a developing incident without forcing every anomaly into the same escalation path. Recorded evidence has value, but it cannot substitute for intervention during the event. Staffing ratios deserve scrutiny because human monitoring can fail when attention is divided across too many feeds. A lower camera-to-agent ratio can shorten the distance between observation and decision, especially when multiple events surface at once. Managers should look past camera count and ask how many feeds each specialist handles, what happens when uncertainty rises, how incident context is preserved and how work is elevated to a supervisor. Those mechanics say more about response quality than the number of cameras deployed. Workload design therefore belongs in the buying discussion, not merely in vendor staffing detail. False-alarm control is tied to context, not detection alone. A useful service should verify activity before calling police and remain involved after dispatch if conditions change. Two-way voice communication matters here because it allows monitoring staff to challenge a person and request identification. Visible strobes or warnings can create a second intervention before police response. That graduated approach can reduce unnecessary calls while preserving escalation when a person refuses to leave or cannot be verified. Escalation should stay proportional to what the operator can actually verify in the moment. Site design and service terms also shape performance. Camera placement should reflect perimeter exposure and activity patterns, while installation crews need to adapt as construction or property use changes. Buyers should expect a clear proposal that shows where equipment will sit and what it will cover. Contract structure deserves equal attention. Month-to-month options or reasonable cancellation terms make performance easier to judge on continued service rather than sunk commitment. LiveGuardTech fits this buying logic through a service model centered on live human review and direct intervention. Its monitoring specialists watch live feeds with a low camera-to-agent ratio, then use two-way communication and activated strobe lights to challenge suspicious activity before police escalation. Site assessments inform camera placement, while LiveGuardTech's field technicians handle installation and service. Its proprietary monitoring software supports movement of video between agents and supervisors, and its teams can provide police with secure access to a live feed during an active response. The company also offers standard night-and-weekend monitoring or 24/7 coverage, with remote camera access through its CamView platform. For buyers that prioritize fast human judgment over alert-only monitoring, LiveGuardTech warrants close consideration. ...Read more
Cybersecurity has become a business concern that extends beyond IT departments. A security breach can interrupt services, expose customer information and damage trust. Managed security services give organizations access to external security specialists who monitor systems, investigate suspicious activity and respond to potential threats. For businesses across APAC, these services offer a practical way to strengthen cyber defense without building every capability in-house. The role of managed security services is also changing. Businesses once relied heavily on external teams to monitor alerts and maintain security tools. Today, they expect providers to investigate threats, explain risks and work closely with internal teams when incidents occur. The focus is shifting from monitoring systems to helping organizations make better security decisions. A Changing Cybersecurity Landscape Managed security services cover a range of functions, including network monitoring, endpoint protection, cloud security, vulnerability management and incident response. Some providers also offer managed detection and response, which combines continuous monitoring with threat investigation and action to contain suspicious activity. Demand is growing as organizations adopt cloud applications, support remote work and connect more business systems. Each new connection can create another point of entry for attackers. Internal security teams must keep track of these environments while managing everyday IT responsibilities, making specialist external support an attractive option. The APAC market presents its own challenges. Businesses operate in countries with different levels of digital maturity, infrastructure and cybersecurity expertise. Large enterprises may have dedicated security departments but still need outside specialists for advanced threat detection or incident investigation. Mid-sized organizations may depend more heavily on external providers because maintaining a full security team can be difficult. The business case extends beyond preventing attacks. Effective security monitoring can help limit disruption, protect sensitive information and give leadership teams a clearer picture of potential risks. For organizations that rely on digital services to serve customers or manage supply chains, a delayed response to suspicious activity can have consequences well beyond the IT department. AI And Cloud Security Change The Market Artificial intelligence is changing how security teams review alerts and investigate unusual activity. AI-assisted tools can identify patterns in large volumes of security data, highlight suspicious behavior and provide analysts with useful context. Automation can also handle repetitive tasks, giving security professionals more time to investigate incidents that require closer attention. However, these tools are not a substitute for human judgment. Attackers can use AI to create convincing phishing messages, automate malicious activity and adapt their methods. Security teams must also account for risks associated with AI applications used within their own organizations. Managed security services need to address these developments without treating automation as a complete solution. Cloud adoption is creating another area of demand. Many businesses now operate across private infrastructure, public cloud environments and applications managed by external providers. Security teams need visibility into these different systems to identify suspicious activity and understand whether an incident in one environment could affect another. Managed detection and response is gaining importance because businesses want more than alerts. They need specialists who can investigate potential threats, determine their significance and take agreed-upon action. The exact scope varies by provider, making it important for buyers to understand whether a service includes active threat hunting, incident containment and recovery coordination. “Managed Security Services Cannot Remove Every Cybersecurity Risk. Their Value Lies In Giving Organizations Access To Specialist Knowledge, Continuous Monitoring And A Defined Response Process.” What Buyers Should Look For Choosing a managed security services provider requires a clear understanding of responsibilities. Buyers should establish which systems the provider will monitor, how incidents will be classified and who has the authority to act when a threat is detected. Unclear responsibilities can delay decisions at the moment when a quick response matters most. Response procedures deserve particular attention. Organizations should understand how quickly the provider escalates serious incidents, whether analysts are available outside normal business hours and how evidence is preserved for investigation. Reporting should explain what happened, why it matters and what action is needed rather than simply presenting a long list of alerts. Data handling also requires careful consideration. Businesses operating in APAC may have different requirements for where information is stored, who can access it and how it is transferred between locations. Buyers should examine the provider's data practices and confirm that its service arrangements fit the organization's local obligations. The difference between a basic service and a mature provider often lies in the quality of its investigations and communication. Experienced teams can connect security events, distinguish routine activity from genuine threats and explain their findings in business terms. They should also share lessons from incidents and identify weaknesses that require attention. Implementation can still be difficult. Older systems, incomplete asset records and disconnected security tools may prevent providers from seeing the full picture. Organizations also need to prepare internal teams for new escalation procedures and agree on how external specialists will coordinate with IT, legal and business leaders when necessary. The Future Of Managed Security Services Managed security services are likely to become more closely connected with identity protection, cloud security and broader risk management. AI will play a larger role in analyzing activity and prioritizing alerts, but human expertise will remain important for complex investigations and decisions involving business risk. Buyers are also likely to place greater emphasis on clear reporting and evidence of service quality. The number of alerts handled offers limited insight on its own. Organizations need to understand whether threats are being investigated effectively, whether response procedures work and whether recurring weaknesses are being addressed. Managed security services cannot remove every cybersecurity risk. Their value lies in giving organizations access to specialist knowledge, continuous monitoring and a defined response process. For APAC businesses, choosing the right service will depend on how well the provider understands their systems, communicates risk and works with internal teams to protect essential business activities. ...Read more
Cybersecurity and regulatory compliance have been interwoven business disciplines as organizations rely increasingly on digital systems. Organizations have to take care of their customer information, finances, intellectual property, operations, and technology infrastructures in ever-more distributed environments. Cyber protection of these assets goes beyond individual security controls. There should be an effective solution to the coordination between the operations of cybersecurity and compliance that integrates all aspects, such as risk management, monitoring, governance, and regulations, within a real-world framework. An effectively structured process will assist organizations in ensuring secure processes. Strengthening Security through Integrated Operations The traditional areas of cybersecurity operations have been to detect malicious activity, investigate security incidents, manage vulnerabilities, and safeguard important systems. The areas of compliance operations include adherence to laws, regulations, contracts, and policies. Operating these two areas of operations separately will lead to inefficiencies where duplication may occur, or the link between the two may be overlooked. The first step in achieving a unified operating model is to assess the information resources of the organization, business processes, technology infrastructure, and the corresponding requirements. The security team will then be able to create controls that take into consideration both the operational risk and the compliance needs. Controls such as access control, endpoint protection, network monitoring, encryption, vulnerability management, and security awareness can all be in line with policies and governance goals. Continual monitoring is yet another important aspect. Threats and technologies are always changing, and compliance obligations might have additional expectations in terms of the evidence to be provided, reporting obligations, and control effectiveness. Through continual monitoring, businesses are able to detect any discrepancies and investigate them before they turn into major business issues. Automated notifications, central dashboards, and workflows can help prioritize activities based on business impact. Improving Governance, Risk and Compliance Coordination An effective process of cybersecurity and compliance relies on good governance. The organizations require well-defined roles of security leaders, the IT department, compliance officials, risk managers, and business representatives. Governance processes ensure that everyone knows whose responsibility it is to evaluate the controls, escalate incidents, or provide the regulatory evidence. Moreover, the governance framework helps to define the processes of policy approval and risk assessment. Risk assessments offer the basis for these practices. Instead of using the same control measures in all systems, companies have the ability to assess their risks based on asset importance, data sensitivity, exposure, dependence, and business impact. This method assists in focusing efforts in places where implementing security measures is more beneficial. It is necessary to revisit risk assessments from time to time due to the fact that risks may change in light of new developments. Centralized documentation and evidence will further enhance the compliance management process. It is common for organizations to have to provide evidence of policy approval, control functioning, monitoring of employee activities, and resolution of problems. Documenting the evidence in a systematic way will lessen the work needed during internal audits, customer audits, and regulatory inspections. It will also increase visibility on the part of management as far as controls and corrective actions are concerned. Building Sustainable Cybersecurity Operations Sustainability in cybersecurity demands that an organization integrate its technology, people, and processes. The security tools may be able to detect possible threats, but achieving successful results requires individuals who are well-trained and comprehend the business objectives and procedures in place. Training can allow workers to see their security roles, and exercises can assess whether these teams react effectively. A final topic worth noting is that of third-party risk. Third parties such as suppliers, technology partners, and even service providers could have access to organizational systems or even confidential data, and therefore become dependent upon the organization for security and compliance. Diligence, assessments, monitoring, and contract stipulations can all assist organizations in recognizing and managing their third-party relationships and any associated risks. Additionally, an organized third-party program can ensure that third parties meet certain security expectations. Incident response must be built within the larger compliance program. There must be established procedures for detecting, containing, investigating, resolving, and reporting any security incident. Established communication methods and assigned roles will help in reducing any delay during the incident response process. It will also make it easier to find out weak controls in the process. As the regulatory standards keep changing, firms would have to ensure that they have cybersecurity strategies that can be adjusted without creating any operational overhead. Compliance operations solutions that are scalable could help organizations create control standards, measure performance, organize evidence, and find gaps. The aim is not only to meet different regulatory standards but also to create security and compliance standards for effective trade operations. This integrative approach will also allow leaders to assess security investments based on concrete results of operation, finance, and regulation. Cybersecurity and compliance should be seen as integral elements of business management. Companies that incorporate monitoring, governance, risk management, documentation, and responses gain increased visibility of their technological environment and greater accountability. Through the integration of their security processes with their management objectives, companies can address their digital risks in a more systematic way, make decisions based on facts, and establish a solid foundation for future growth. ...Read more
When the threat of a security incident occurs, businesses usually identify their response in the short term, but they have to rely on digital forensic services to help them understand what happened and take appropriate action. The growing role of digital forensic services in incident response is directly related to the organization’s need to document and analyze data to find out the nature of the security violation, which requires time. The role of digital forensics in incident response management covers a wide range of activities, from analyzing compromised digital media to examining all relevant factors and circumstances related to the incident in order to reconstruct the sequence of events leading up to it. The organization’s internal security team and external digital forensic experts collaborate during this process, with each party focusing on tasks in accordance with their responsibilities.  However, the involvement of digital forensic experts goes further, as the analysis includes collecting and recording evidence, which helps to determine the consequences of the incident for the business. At the same time, the timing of the intervention is also relevant since the digital evidence is often dynamic and therefore requires a timely analysis. During the incident response, forensic experts are often involved in investigations at the earliest stages, which demonstrates the relevance of turning to them as soon as possible after the incident. Companies often rely on digital forensics to preserve the integrity of the evidentiary data set, which is critical to the investigation. Internally, the security team handles the response while external experts handle the evidence collection and analysis. The two sides are in constant communication, and the experts are responsible for providing the security team with specific evidence, which allows them to perform their tasks efficiently. Documentation is a key part of digital forensics. Organizations pay close attention to how accurately and completely evidence is recorded. Proper documentation allows businesses to review specific cases later if needed. Because of this, companies often select incident response experts who can record evidence in a clear and structured way.  During an investigation, businesses also have to think about how preserving evidence might affect business continuity. This means finding a balance. Experts help companies choose the best way to preserve evidence so that operations can keep running with as little disruption as possible. As a result, it is necessary to understand that the role of digital forensics in incident response covers various aspects of the security breach investigation. Companies are increasingly relying on external experts to support internal teams and help document and analyze evidence, leading to the identification of the causes of the security incident. ...Read more
