With the start of the pandemic, the world went online. Going digital has presented many growth opportunities for businesses, but has also put them in jeopardy due to the rising number of cyber threats. According to Verizon’s 2021 Data Breach Investigations Report, 95 per cent of losses from breaches fall between $826 and $653,587.
Poor security can lead to losses or signal bankruptcy in the near future. Breached companies lost an average of 3.5 per cent on the NASDAQ in six months after the breach. There are many cyber threats that companies across various industries may face. Taking action to improve their understanding of security threats can help companies to equip themselves with the necessary tools to minimise risks. Most security breaches can be divided into the following three categories:
Even though most companies have already enforced security measures such as VPNs, antivirus software, and firewalls, this is not enough to protect against all types of malware. One of the best ways to deal with cyber-attacks is partnering with trusted providers of cybersecurity services. An experienced vendor can help you implement SIEM cybersecurity systems to monitor and immediately react to security alerts within the system.
SIEM is a process that encompasses gathering logs from applications and devices inside the network, monitoring and detecting attacks and indicators of potential attacks, analysing detected events and anomalies, and notifying security personnel or automated reactions to events. In general, SEIM aggregates all logs in the system and provides real-time analysis of security alerts generated by applications and network hardware.
A SIEM cybersecurity solution collects event data from different sources within a company’s network and uses different rules to correlate those events and detect threats. These rules are called correlation rules. There are several types of these rules, including:
SIEM systems offer several benefits for enterprises. Logs collector sends selected audit logs from the system's devices/applications to ingest components for further storage. The search engine within SIEM system is used for visualisation, reporting, alerting and ad hoc querying. Other advantages of SIEM implementation include:
There are many use cases for SIEM solutions, from assisting security teams with identifying and alerting security breaches to compiling regulatory reports. Let's look at some applications based on the classification provided by computer security researcher Chris Kubecka at the hacking conference 28C3:
Over the years, ELEKS has successfully launched dozens of security-related projects. The experts in our Information Security Department have hands-on experience and have obtained many internationally recognised security certifications, including C|CISO, ISO 27001 Lead Auditor, CCSP, CCSK, CySA+ and CEH.
ELEKS’ security team performed information security risk assessment and business continuity testing for ESET, a leading global cybersecurity provider. Afterwards, we consolidated the report with the potential threats and vulnerabilities based on the results. With the help of this report, ESET were able to define weaknesses and execute necessary security measures. Learn more about the case study.
For Sayenko Kharenko, another of our customers, ELEKS executed an audit of business processes, namely risks, objectives and other significant aspects of the law firm’s data management. We helped our customer to create an effective basis for demonstrating their GDPR compliance and eliminating issues related to storage, processing and transmission of personal data within the company. You can read more about this project here.
The modern technological world provides lots of opportunities online. And while most businesses have already applied some security measures, it is still not enough to stand against the rising number and complexity of cyber-attacks.
One of the first steps in the battle against cyber threats is the implementation of SIEM cybersecurity systems, which offer real-time monitoring, correlation and attack mitigation capabilities. They also enable the storage of historical data for further analysis and even offer replay functionality to enable companies to simulate attacks for training purposes. SIEM options include off-the-shelf solutions or tailored solutions that cater for specific business needs.

The breadth of knowledge and understanding that ELEKS has within its walls allows us to leverage that expertise to make superior deliverables for our customers. When you work with ELEKS, you are working with the top 1% of the aptitude and engineering excellence of the whole country.
Right from the start, we really liked ELEKS’ commitment and engagement. They came to us with their best people to try to understand our context, our business idea, and developed the first prototype with us. They were very professional and very customer oriented. I think, without ELEKS it probably would not have been possible to have such a successful product in such a short period of time.
ELEKS has been involved in the development of a number of our consumer-facing websites and mobile applications that allow our customers to easily track their shipments, get the information they need as well as stay in touch with us. We’ve appreciated the level of ELEKS’ expertise, responsiveness and attention to details.
