What is User Behavioural analytics?
User Behavioural Analytics refers to the tracking, collection, and assessment of user data and its monitoring using monitoring systems. UBA technology uses the analysis of historical data logs, network and authentication logs in order to determine traffic patterns that are a result of user behaviour; both suspicious and normal.
Meant to provide insights into the cyber security teams, the configuration of the systems can allow them to be modified to make user authentication difficult.
Uses of UEBA
Initially developed in the 2000's to help marketing teams focus on their customers and their patterns, today with the advancement in technology, the use of behavioural analytics have expanded to include two main functions:
Using the technology for a single user may no help much in finding any malicious activity, running it for multiple users for organisation-wide solutions may help detect any malware or cybersecurity threats, compromised endpoints and insider user threats to the organisations.
How does behavioural analysis help cybersecurity
Within an organisation’s network, which parties are having access to the network? What is the purpose they are using it for? And are their actions permissible? All of these are critical questions that a behavioural analysis can respond to.
Using advanced techniques such as log analysis, signature detection, advanced analytics, along with Artificial Intelligence techniques in order to block any malicious entries into the organisation’s protected network.
In the presence of benchmarks for usual or normal user actions, it becomes possible to identify any irregular patterns that arise outside of the regular trends and to take necessary action before the advent of any adverse effects.
Behavioural analysis is an ideal way to detect any anomalies in the following features:
Employees usually work certain predictable hours of the day. In case an employee appears to "log in" at unusual hours there is a possibility that it may be a threat. Further investigation may be initiated by the system, which might ask for verification.
The use of a public computer or logging from a device that is not recognisable by the system may be a threat, and unauthorised personnel may be using the system to access the network.
An employee logging in from another location with a different IP address may raise a red flag. Similarly, a user with a changing IP address denotes a user using a VPN to mask the actual location of the user. IT may be due to any reason however it raises a red flag within the system.
Unauthorised or unusual applications that do not go with employees’ usual tasks may pique the interest of the cybersecurity. The usual applications may include applications that are used to send and receive data to or from other devices.
Behavioural analytics may have some intriguing aspects. It can also use the typing speed and patterns, movement of the mouse and the use of other endpoint devices to detect any anomalies. This could go on to generate any alerts.
The simple understanding of how data flows in your organisation may also help to highlight any anomalous behaviour. Behavioural analytics that focuses on network behaviour work by specifying how the network for your organisation should look like. With the standard set, any anomalies are highlighted instantaneously.
Elimination of suspicious behaviour using analytics
Although the approach to use behavioural analysis for organisations does not include a one size fits all model. The organisation using behavioural analytics to enhance their cybersecurity should understand how and where security analytics can be used in an attempt to strengthen the cybersecurity of their organisation.
Most businesses can create a model of a normal network behaviour which can be used to determine any anomalies, in order to proactively work against any arising threats.

What security regime to adopt in managing the privacy of the customer data? There are different options but the European Union has outlined strict proposal that address the importance of safeguarding the customer data. The assessment of the security parameters is now determined through a roadmap. The execution is best applicable with the help of experts.
Implement strategy must be justifiable:
The design of the platforms that launch the procedure must be immaculate. The ability to proffer maximum leverage will validate the investment. For instance the access to data from different locations open up new avenues of breach. How could this be mitigated? Familiarity with the tools that deliver an all-encompassing solution will be a big talking point in future.
The insecurities in the corridors of security can be dealt with the holistic approach strategized by GDPR risk assessment.
You already know how much the business can cost in the wake of security breach. Alas! The outcome is far worse than initially anticipated. The management of risk at each level requisite determination and all-inclusive planning. A thoroughly functional security framework is context based. The environment in which the business operates and the perspective can help perceive better anticipation of the potential threats.
The security deception in the online medium:
IoT has already given sleepless nights to enterprises. The magnanimity of the big data and its prevalence has actually developed an ecosystem of hopelessness. It is argued that the security issues has gone beyond the frontiers of privacy. Designing an irresistible landscape of data protection with security consulting is invaluable in limiting the threats posed by IoT. An important feature is the growing affordability that connectivity has offered. Tight security budgets must expand. There is no way out. The identification of different variants of cyber-attacks and their prevention will involve considerable spending on security as found out in a study.
IoT will comprise to approximately 27% of the security breaches still the lack of effective positioning of resources will spur up lackluster outcomes. Therefore, the acceptable threat level will never be envisioned due to lack of focus. Don’t say what to do? Security issues are not about whim. It is an obligation of the highest order. The realities of network security and the actual gaps needs tangible measures. Experts can profoundly reflect on the means and the reasons of breach that may be experienced in future.
How can you liberate yourself from vulnerabilities? You need to have a dedicated and transparent system that can exercise effective procedure in a systematic manner.
Any inconsistency must be eliminated in its entirety. When designing a framework for preventing accidents you have to ascertain the relationship between regular and irregular activities.
Experts recommend that the comprehensive competency of a system is only realizable when you regularly check out for inconsistencies.
The challenges for network security are mounting. What you need to proactive approach in the sea of network security where intruders are waiting for your mistake.
The satisfaction is a qualitative construct, but the approval of the different aspects must be in congruence. The procedures, people and the system must be regularly inspected to inspect the health of the system.
This checkup can instill new ideas that can prove vital for future security considerations. In order to deliver an immaculate service experience across the network it is important to bridge the gaps hindering in securing the perimeters of the network.
The ownership of actions is the platform from where an honest evaluation of the system integrity can be launched in its entirety. No less than absolute dedication is necessitated in raising the bar for system security.
Network security assessment can set up formidable criteria in outlining the system integrity and how the missing link can be treated.
Before engaging the expert the management must get totally involved with the concept. Industry experts highlight the need to design benchmarks and maintenance procedures in objectively inspecting the vivacity of the system.
The mindset of change is important in understanding the vitality of the issue. If the activity is taken as a routine procedure, then the floodgates might open for the hackers to disrupt the system.
Document what is being inspected and why. The checklist must undertake previous evaluation reports to highlight the risk exposures.
The threat perception can only be designed when the management is aware of the potential loopholes.
The development of various scenarios is also important in fulfilling the rationality of the activity. The evaluation process can analyze the impact of each variable on the security.
The efficient functioning of the system entails undertaking the realities in a comprehensive way.
The optimization of resources is also quite significant as it can impact on the incurred cost for the evaluation procedure. Network security assessment can mastermind the effective evaluation procedure.
