SIEM As a Robust Solution for Detecting Threats in Time

Security Information and Event Management, or SIEM for short, has a long tradition in IT security. Nevertheless, it is highly topical and can be seen as the basis of „next generation security“. At current trade fairs and events, we hear a lot about security analytics or security intelligence. Both terms are associated with the detection of advanced attacks. The acronym SIEM, on the other hand, is associated with classic security information and event management. SIEM is and remains the central approach for collecting and analysing security-relevant information and data on security events, making it available in compliance reports and providing the basis for prompt responses to security incidents with alerts. A robust SIEM solution also offers management of security-relevant data and analyses and thus enables the search for events in the past to support IT forensic investigations. How do SIEM tools work? A modern SIEM requires three core competences – data collection, analysis and response – to ensure the security required in today’s hybrid and multi-cloud environments. The job of a SIEM refers to: If compliance reporting is an important factor for the organisation, a SIEM should also be able to create dashboards and ensure that security policies are being enforced. What SIEM is used for? A Security Information and Event Management tool is used for comprehensive security management in information technology environments. SIEM tools are designed to collect, aggregate, analyze, and report on security data from various sources within an organization’s IT infrastructure, so the primary functions of a SIEM tool include: SIEM as a part of the mandatory security program Without appropriate SIEM solutions, companies are unable to analyse the large number and the variety of logs provided by the IT systems they use. That is why Security Information and Event Management is an integral component of a comprehensive security program. SIEM solutions empower organizations to proactively detect, investigate, and respond to security incidents by aggregating and analyzing vast amounts of data from disparate sources across their IT infrastructure. The range of logs extends from the log files of individual applications to the operating systems of (mobile) endpoints and servers, hardware firmware, IT security solutions, networks and clouds. If the security-relevant information from the various data sources is not analysed promptly enough, potential attacks and incidents could not be properly detected or could be detected too late. Without a central location that collects, analyses and consolidates the logs for reports, it is also virtually impossible to provide the necessary compliance evidence for IT security. IT forensics also needs SIEM-based support in order to better uncover the traces of attackers and possible vulnerabilities that have been abused. The decision as to which SIEM system is the right one, must be made without any fail. The market is rich in solutions that offer different capabilities, features and advantages. Companies should pay particular attention to whether their individual requirements are met, i.e. the IT systems to be supported, whose log data must be able to be read out, the available interfaces and data formats, but also the available reports, which must match the compliance requirements that the company faces. Furthermore, the cloud plays an important role here. On one hand, the solution of choice should also be able to take into account the cloud solutions used, i.e. support cloud logging. It should also be possible to integrate security-relevant information that is available via the cloud. The so-called „threat intelligence feeds“ from security providers deliver via the cloud an important additional information that a company’s SIEM cannot have, based on its own data. The early detection of attacks depends heavily on the information base of the SIEM, so additional data on possible threats and attacks from security intelligence services is very valuable. Concusion As cyber threats continue to evolve in complexity and sophistication, the importance of SIEM within a comprehensive security program cannot be overstated. Organizations that leverage SIEM effectively are better equipped to stay ahead of adversaries, safeguard critical assets, and uphold trust with stakeholders in an increasingly interconnected digital landscape. Embracing SIEM as a cornerstone of cybersecurity strategies is essential for organizations committed to maintaining resilience and staying abreast of emerging threats in today’s dynamic threat landscape.

Five Еffective Approaches for Security in Multi-Cloud Environments

Uncategorized / Von Ina Nikolova

Multi-cloud can bring great benefits to a company. For example, more and more companies are utilising the high degree of flexibility to develop and host applications natively in the cloud. These applications consist of so-called micro-services – services that only take on individual or a few tasks, exist independently of each other and are loosely coupled. This modular software architecture enables companies to implement changes to cloud-native applications quickly and easily. To get the best out of their multi-cloud environment without playing into the hands of criminals, organisations need a security approach that enables a consistently high level of security and seamless compliance management across all clouds. What is Multi-Cloud security? To understand multi-cloud security, you need to know the difference between multi-cloud and hybrid cloud services. The term „multi-cloud“ is used when cloud services from multiple cloud service providers are used. With this concept, your company can oversee separate projects in the different cloud environments of multiple cloud service providers. Like „multi-cloud“, „hybrid cloud“ also includes several cloud environments. However, in a hybrid cloud environment, work is distributed across a common workload system consisting of public cloud, local resources and a private cloud. A common advantage of hybrid cloud and multi-cloud is their adaptability and cost efficiency. Both support the highly flexible management of resources and data migrations that take place between local resources and the cloud. In addition, companies benefit from more control and security when operating a private cloud in a hybrid cloud environment. More and more industries are switching to multi-cloud and hybrid cloud infrastructures, exposing them to the typical risks of an unprotected cloud environment. These include an increased risk of data loss, unauthorised access, lack of transparency in multi-cloud environments and increased non-compliance with regulations. A single cyberattack can have negative consequences for the company and lead to a lack of customer confidence and loss of revenue and reputation. In this article PATECCO will share five useful tips that will sharpen your focus on the security aspects of multi-cloud environments. 1. Build up expertise for multi-cloud As a first step, companies need to build up the necessary expertise for multi-cloud environments. This involves topics such as containers, container orchestration, runtime environments or cloud-native development and provision. In many cases, this requires investment in employee training and development. 2. Establish visibility of your cloud workload It’s almost a mantra, but nevertheless the basis of any security strategy: I can only protect assets that I know. In the context of cloud and multi-cloud environments, this applies in particular to applications and the corresponding information stores. The first step is therefore always to determine what type of information and applications are used in the cloud and by whom. In many complex organisations, however, this is one of the first hurdles because the use of different cloud services has often developed historically. 3. Focus on centralised services and tools for scanning and monitoring In particular, tools, that can not only be used in different cloud environments, but can also transmit their results to a central console, are ideal for keeping the dashboards and processes required for monitoring up to date. As a rule, this allows all cloud systems used by a company to be monitored. In recent years, a new category of cloud monitoring tools has been developed, which is summarised under the term Cloud Workload Protection Platforms (CWPPs). A CWPP protects the workloads housed in the cloud from attacks by using techniques from the areas of network segmentation, system integrity protection and application control, behaviour monitoring, host-based intrusion prevention and, optionally, anti-malware solutions. In many cases, manufacturers also offer functions for zero trust, micro-segmentation and endpoint detection and response in this area. By focusing on logging and centralised services and tools for scanning and monitoring a multi-cloud environment, security teams can develop a coherent and sustainable strategy for their protection. This means that any problems and security incidents that arise can be recognised and rectified more quickly. In addition, integration into an overarching IT security strategy will sooner or later also make it easier to manage cloud solutions. 4. Recognise vulnerabilities It is a common misconception that moving to the cloud also means getting rid of vulnerabilities, or that these are now primarily a problem for the cloud provider. This is only partially true. Although reputable CSPs (cloud service providers) usually protect the vulnerabilities in their own infrastructure very reliably, the number of data breaches at third-party providers, such as cloud service providers, is rising sharply. The reason for the increased number of attacks on cloud service providers is generally not their lax security precautions (although this does happen). Rather, the cause is often due to incorrect or careless security settings by cloud users. One example of how this can occur is the temporary use of services, as often happens for marketing campaigns in which customer data, among other things, is used. If the services are not carefully cleaned up after use, such orphaned databases can quickly become a ticking time bomb that can cost a company dearly later on. 5. Trust is good, control is better All preventive measures, such as access restrictions, authentication procedures and data flow controls, however sophisticated they may be, can be circumvented or cancelled out sooner or later given enough time and the right methods. Security monitoring, which continuously observes the security-relevant processes and alerts the IT security managers in the event of deviations, helps to prevent this. This is easy to do within your own four walls because all the necessary information such as network, system and application logs is directly accessible. However, this traditional approach fails when this information is stored in the environment of one or more cloud providers. It is therefore important to ensure that the CSP has the appropriate functions for security monitoring when selecting the appropriate CSP.

Role-Based Access Control as a Cybersecurity Imperative for the Business

Uncategorized / Von Ina Nikolova

Defining and granting access rights is a constant challenge for IT departments. Managing access rights based on a role-based approach makes controlling system authorisations for users in complex IT environments clear and simple. On one hand, as many regular users – whether employees, external contractors or others – require the same or similar access rights to perform their work, the assignment of access rights can be greatly simplified by grouping employees based on their tasks and associated competences within the organisation. On the other hand, a lack of access control or automatic provisioning of rights and access can be costly and risky for the enterprise in a number of ways. It means that new employees and contractors may not be up and running as quickly as necessary, they may gain access to systems they shouldn’t have access to, they may retain their access rights when they change roles or leave the organisation, and they may inadvertently compromise the organisation’s security profile. The power of RBAC Role-based access control is a procedure for managing and controlling access to files or services. Instead of giving users in the network direct access rights to various systems or making spontaneous decisions about who can access what and for how long, access is granted according to a role previously assigned to the user. When used systematically, RBAC reduces the risk of a user being granted too much access and thus promotes the implementation of a least privilege strategy. With clearly defined roles, protocols are created that specify exactly which role is suitable for which type of user, which prevents inappropriate inheritance of authorisations. In the event of a compromise, authorisations can also be blocked extremely quickly and on a large scale, effectively preventing the spread of cyberattacks. This is the reason why the RBAC concept is often used, particularly in companies with more than 500 employees. This ensures that employees always have the rights they need and that there are no interruptions to operations. RBAC allows organizations to define roles and permissions based on their specific business requirements and security policies. Roles can be tailored to reflect different job functions, departments, or projects, and permissions can be fine-tuned to accommodate variations in access needs across different user groups. With RBAC, companies can react more flexibly to employee changes according to the Joiner, Mover Leaver (JML) process. Especially when employees join, change departments or leave the company, RBAC makes work much easier and safer. At the same time rights can be granted and withdrawn at any time via role memberships, which makes RBAC very adaptable and dynamic. Role-Based Access Control also makes the time-consuming assignment of individual authorisations obsolete by predefined authorisations to roles once and can be rolled out to several people in one go or withdrawn again. If the roles are named in a way that is easy to understand, this also increases Transparency and traceability on the user side. The allocation of individual authorisations without RBAC is not only time-consuming. It also means less control and overview of who has access to what. It also leaves room for errors and over-authorisation. Thus, security gaps can arise if the individual authorisations are no longer withdrawn or are retained for longer than necessary. If users are given too many authorisations, this can lead to errors. With a well thought-out and predefined authorisation concept, the company not only saves work but is also on the safe side: access rights are defined exclusively via the role concept. Over-authorisation of individual employees is thus avoided in accordance with the Principle of Least Privilege (PoLP) in order to fulfil compliance requirements. In this way, RBAC helps to significantly increase efficiency and security in IT and throughout the entire company. Changes are made automatically, rights no longer have to be applied for and assigned individually and the waiting time for approval is also eliminated. This not only makes managing access rights easier, but more error-resistant, as well. Role-based access control includes role authorisations and user roles and can be used to meet a variety of company requirements, from security and compliance to efficiency and cost control. With role-based access control, organisations reduce both the complexity of assigning access rights and the associated costs. It provides the ability to review access rights to ensure compliance with various regulations and streamline processes so that new employees are up and running from day one by pre-defining which systems the new employee should have access to based on their role in the organisation. RBAC facilitates auditing and reporting by providing a structured framework for access control. Audit logs can track user activities and access attempts based on role assignments and permissions, enabling organizations to monitor compliance with regulatory requirements and internal policies. RBAC helps demonstrate accountability and transparency by documenting who has access to sensitive resources and how access is being used, which is essential for compliance audits and investigations. RBAC supports segregation of duties by defining roles with mutually exclusive sets of permissions. This prevents conflicts of interest and reduces the risk of fraud and errors by ensuring that no single user has excessive privileges that could be abused. SoD controls help prevent unauthorized activities such as unauthorized transactions, data tampering, and fraud, thereby enhancing security. Having in mind the above listed advantages, we can conclude that RBAC is important for businesses in terms of enhanced security, facilitated compliance with regulatory requirements, mitigated risks, and improved operational efficiency. By implementing RBAC, businesses can strengthen their security posture, protect sensitive information, and maintain trust with customers, partners, and regulatory authorities.

Best Practice Tips for Successful Customer Identity and Access Management

Uncategorized / Von Ina Nikolova

Identity and Access Management is now considered a secure alternative to passwords as an authentication method. However, in addition to security, the user experience also plays an important role. With these six tips, providers can ensure an optimal customer experience and therefore satisfied customers. Securing critical data is an essential part of digital transformation. Many companies still use passwords as their main authentication method. However, as a relic of the pre-digital age, it has long been declared a major insecurity factor and obsolete. Identity and Access Management (IAM) offers an effective and less costly alternative. The key to a successful IAM approach is the correct identification and profiling of customers based on data. This is the only way for companies to correctly understand the needs and interests of users and offer appropriate services and products that guarantee a personalized customer experience. Both sides benefit from this relationship, as companies can increase customer loyalty and business profits and users receive the information and services they really want. While IAM is being used more and more, the demands on its functionality are also growing and it now has to do more than just provide security. A successful solution must also guarantee customer satisfaction and serve multiple stages and platforms of customer contact without overburdening or scaring off the end user. Nevertheless, companies should consider the implementation of a suitable customer IAM solution (CIAM) as a top priority, as it can have a direct impact on the company’s success as the link between IT, marketing and sales. With the following six tips from PATECCO, companies can successfully optimize their customer IAM for security and customer satisfaction: The right balance between usability and security While ease of use is a critical factor, it should not be built at the expense of privacy or lax practices for accessing company data. Just as front doors are not opened to just anyone, companies should be welcoming but not allow access to cyber thieves. Evaluate IAM solutions according to scalability and availability The scope of customer IAM programs is often much larger than that of employee IAM programs. Customer populations can number in the millions and fluctuate at any given time, so organizations should evaluate IAM vendors on their ability to scale, branding, customization, availability and performance. Vendors should be selected based on their ability to adapt to current and future business needs. Customers should have immediate access to applications Consumers have no patience for long waiting times when logging in and registering. With poor performance and slow responsiveness, users quickly abandon apps and switch to the competition. Therefore, customer IAM solutions should offer response times of just a few milliseconds. Existing technologies should be integrated Let’s be honest, it’s never easy to start from scratch. Especially when companies have been working successfully with legacy technology for years. Therefore, it can sometimes make sense to build on existing IAM investments. Leveraging existing identity tools, even if they are separate instances, can potentially reduce the cost of technical support, training and licensing. In these cases, organizations need to ensure that their customer IAM solution is designed to integrate seamlessly with existing technologies. Multi-platform is a must Even a single customer uses multiple platforms to engage with the brand: desktop and mobile web, phone and in-person interactions. This leads to an explosion of new use cases for customer identity – not to mention unique technology requirements. Organizations should ensure that their customer IAM solution can not only address current browser and software-based applications across these platforms, but has the vision and capabilities to serve future needs such as the Internet of Things, Big Data, product development and risk management. Implementation of various authentication methods Every customer is unique and has their own preferences. Just as online stores offer a variety of payment methods such as credit card, PayPal, etc., CIAM solutions should provide a variety of authentication options to suit every taste. Social logins, SMS texts and biometric authentication methods offer different customers the convenience they need. Companies can thus combine data protection with a positive customer experience. At the heart of successful customer IAM is always the positive customer experience, which ultimately has an impact on overall business success. Companies must find suitable solutions to keep customer satisfaction high and personalize services better. This is the only way for companies to stand up to the competition and retain customers in the long term.

Five Recommendations From PATECCO For Security in Multi-Cloud Environments

Uncategorized / Von Ina Nikolova

Traditional security concepts are not enough for multi-cloud environments. What is needed is an approach that enables a consistently high level of security and seamless compliance management across all clouds. These five recommendations will sharpen your focus on the security aspects of multi-cloud environments. The digitalization of companies is progressing and with it the shift away from traditional infrastructure to the cloud. Hardly any company today completely dispenses with the advantages of the cloud. However, this change often does not take place in one step, but rather an ecosystem of applications and cloud storage from various cloud providers is gradually emerging. This is why most companies also have multi-cloud environments. There is nothing wrong with this in principle. However, it should not be forgotten that a company is also responsible for the security of its data and the fulfillment of its regulatory requirements in the cloud. Though, the implementation of these security requirements sometimes differs considerably from the security concepts that we have previously applied in traditional data centers. The following five tips should help to raise awareness of the security aspects in multi-cloud environments. Establish visibility of your cloud workload It’s almost a mantra, but nevertheless the basis of any security strategy: I can only protect assets that I know. In the context of cloud and multi-cloud environments, this applies in particular to applications and the corresponding information stores. The first step is therefore always to determine what type of information and applications are used in the cloud and by whom. In many complex organizations, however, this is one of the first hurdles because the use of different cloud services has often developed historically. Identity is the new perimeter We are used to thinking in a traditional perimeter security environment. What is outside our perimeter is bad. What’s inside is good. As soon as cloud services come into play, this concept no longer works. Our data no longer lies within a clearly defined perimeter but is theoretically accessible from anywhere. In native, hybrid and multi-cloud environments, identity is therefore the new perimeter that needs to be protected. On one hand, this can be ensured through the use of zero-trust architectures. On the other hand, this can be achieved through the technical implementation of secure authentication methods, such as multi-factor authentication (MFA). Applicability and user-friendliness are important when designing these methods. PATECCO also offers corresponding solutions for various scenarios with its Identity & Access Management Services. Recognize vulnerabilities It is a common misconception that moving to the cloud also gets rid of vulnerabilities, or that these are now primarily a problem for the cloud provider. This is only partially true. Although reputable cloud service providers usually protect the vulnerabilities in their own infrastructure very reliably, the number of data breaches at third-party providers, such as cloud service providers, is rising sharply. The reason for the increased number of attacks on cloud service providers is generally not their lax security precautions. Rather, the cause is often due to incorrect or careless security settings by cloud users. One example of how this can occur is the temporary use of services, as often happens for marketing campaigns in which customer data, among other things, is used. If the services are not carefully cleaned up after use, such orphaned databases can quickly become a ticking time bomb that can cost a company dearly later on. Encryption creates trust If I store sensitive data on a data carrier, then I will choose a data carrier that is able to encrypt my information securely. The same principle also applies to cloud storage. This does not necessarily have something in common with mistrust of a cloud provider. But, we have to assume that a cloud provider is fundamentally exposed to the same risks as any other organization. There are people who make mistakes, sometimes even people who deliberately want to harm an organization. It is therefore sensible to prevent these risks in principle by encrypting your workload in the cloud. Trust is good, control is better All preventive measures, such as access restrictions, authentication procedures and data flow controls, however sophisticated they may be, can sooner or later be circumvented or undermined given enough time and the right methods. Security monitoring, which continuously observes the security-relevant processes and alerts the IT security managers in the event of deviations, helps to prevent this. This is easy to do within your own four walls because all the necessary information such as network, system and application logs is directly accessible. However, this traditional approach fails when this information is stored in the environment of one or more cloud providers. It is therefore important to ensure that the CSP provides the appropriate functions for security monitoring when selecting a provider. How can PATECCO support the planning and implementation of your cloud strategy? PATECCO’s cloud security services support our customers to plan their native or hybrid cloud strategy. The Cloud security risk assessment identifies the relevant technical and regulatory risks based on your business/IT strategy and takes them into account in the planning. Our Cloud Access Control and Identity and Access Management solutions help with implementation and operation, regardless of whether your company is pursuing a public or private cloud strategy.

Security Information and Event Management as an Early Warning System for IT security

Uncategorized / Von Ina Nikolova

Security Information and Event Management, or SIEM for short, is of great value for IT security. With a good SIEM strategy, IT risks can be detected more quickly, defensive measures can be focused more precisely and compliance reports can be generated automatically. Today, cyber attacks are often so sophisticated and complex that they are only detected very late or not at all. The longer it takes for an attack to be detected, however, the greater the potential damage. However, there is no lack of indications of new IT threats or traces of attacks. Signs of security incidents can be found in log data, for example. Security Information and Event Management (SIEM)systems collect data from a wide variety of sources such as networks, systems and applications. By analysing this data, security incidents can be detected and remediated at an early stage. In this article you will learn more about SIEM and how it can help you protect your business from security risks. What is a SIEM system? The definition of a SIEM system is a combination of software and hardware that allows organisations to monitor their network security. SIEM systems are able to analyse logs from various systems and generate alerts when suspicious activity is detected. SIEM systems are usually part of a company’s larger security programme and can help detect and combat threats more quickly. SIEM systems can also help monitor compliance with security regulations. SIEM systems are an important tool for network security, but it is important to note that SIEM systems are only as good as the data they process. SIEM systems can only generate alerts if they are properly configured and process the right data (keyword: use case tuning). SIEM systems alone cannot eliminate threats, but they can be an important part of a larger security programme. SIEM systems are most effective when combined with other security tools and measures. A SIEM is a key component of an enterprise IT security management system. It serves as a central event management tool in the Security Operation Centre (SOC). We are happy to support you in the selection and implementation of a suitable SIEM solution for your company. What are SIEM systems used for? SIEM systems are primarily used to monitor and analyse security data. This includes data from firewalls, intrusion detection systems (IDS) and other security systems. SIEM systems can also be used to correlate data from different sources. This gives security analysts a better overview of the security situation in their network. SIEM systems are also used to detect security threats and incidents. How does a SIEM work? A SIEM is an approach to centrally collect and analyse data from various sources in real time. SIEM enables security officers to detect and respond to threats faster by correctly analysing critical information from multiple sources. SIEM typically involves a combination of software and hardware that can collect and analyse security data from networks, endpoints, applications and users. SIEM solutions typically provide a dashboard-based view of the organisation’s security posture and enable security officers to respond quickly to threats. SIEM is an essential component of a comprehensive security strategy. However, SIEM solutions can also be complex and expensive, making them prohibitively expensive for many companies. SIEM is an essential part of a comprehensive security strategy, but it is important to remember that SIEM is only as good as the data it analyses. SIEM solutions need to be carefully selected and configured to ensure that they work properly. Choosing the right SIEM solution If companies decide to use SIEM solutions, they should consider organising workshops either internally or with SIEM partners. This will allow them to coordinate their project scope and timeframe. To determine the size of your organisation and the time it will take to achieve it, you must first determine the use case and prioritise to determine the log sources required. SIEM solutions should be evaluated based on four main factors: Functionality, Cost, Integration and Maintenance. SIEM functionalities must meet the needs of security analysts. SIEM solutions should be able to be integrated into the existing security infrastructure and the SIEM system must be regularly kept up to date. SIEM partners should be regularly audited to ensure that they are providing the required SIEM functionality and services. By reviewing these four SIEM assessment factors, companies can ensure they find the SIEM solution that best suits them. SIEM solutions should be evaluated for features, cost, integration and maintenance to ensure they find the SIEM solution that best suits them. Why do you need a SIEM? As said above, SIEM can help detect and remediate threats faster. SIEM provides real-time monitoring and analysis of security data from multiple sources. SIEM can also help ensure compliance with security regulations. A SIEM can be a valuable tool for companies to improve their IT security. However, SIEM can also be very complex and expensive. SIEM solutions are usually only affordable for large companies. SIEM is also a relatively new concept, so it can be difficult for many companies to implement SIEM. SIEM also usually requires a high level of IT expertise. SIEM is therefore not always the best solution for all companies. SIEM should be carefully considered before a company decides to deploy SIEM. The advantages of Security Information and Event Management at a glance It is impossible to completely avoid security-critical incidents in the modern IT environment – but early detection and recording of dangers increases the chance of keeping any damage as low as possible. If you play to its strengths, a SIEM system provides you with the perfect basis for this. In particular, the real-time reaction to detected security events is one of the decisive strengths of such a solution: the automated algorithms and AI tools detect dangers at a point in time when normal security precautions are often not yet or not at all effective. Another advantage of a good SIEM solution is that all security events are automatically documented and archived in a tamper-proof manner. This makes
