Event Log Monitoring System: Implementation, Challenges & Standards Compliance. Enhance Your Cybersecurity Posture

eventlog analyzerAn event log monitoring system, often referred to as an event log management, is a critical component to IT security & Management, that helps organizations strengthen their cybersecurity posture. It’s a sophisticated software solution designed to capture, analyze, and interpret a vast array of event logs generated by various components within an organization's IT infrastructure such as firewalls (Cisco ASA, Palo Alto etc), routers, switches, wireless controllers, Windows servers, Exchange server and more.

These event logs can include data on user activities, system events, network traffic, and security incidents and more. By centralizing and scrutinizing these logs in real-time, event log monitoring systems play a pivotal role in enhancing an organization's security posture, enabling proactive threat detection, and facilitating compliance with regulatory requirements.

Ensuring Compliance and Business Continuity in a Hybrid Work Environment

compliance in a hybrid environmentIn the wake of digital transformation, the work landscape as we know it has undergone a dynamic shift. People can now work from home, from the office, or anywhere with a stable internet connection. Labeled as hybrid work, organizations have gradually started to adopt this seamless blend between remote work and on-site engagement.

According to the digital readiness survey by ManageEngine, remote work will have a lasting impact with 96% of organizations stating that they will be supporting remote workers for at the least the next two years. While the remote working model offers significant advantages to employees, such as a better work-life balance, it presents significant challenges for organizations in extending office-like network security.

To ensure the success of hybrid work, every organization should address challenges related to security, compliance, and data protection. This article delves into the risks and issues associated with ensuring compliance in a hybrid work environment. Let's dive in.

Key Topics:

Network Compliance in a Hybrid Work Environment

Compliance refers to the adherence of an organization's infrastructure, configuration, and policies to industry standards. In a hybrid work environment where employees are working away from the office, it becomes difficult to ensure compliance. To overcome this, companies are employing a deluge of smart monitoring systems to make sure they stay compliant with industry norms.

Besides legal obligation, compliance also helps in safeguarding networks from security incidents such as breach attempts, overlooked vulnerabilities, and other operational inefficiencies.

Consequences of Compliance Violations

Non-compliance, which refers to the failure to adhere to laws, regulations, or established guidelines, can have a wide range of repercussions that vary depending on several factors. The severity of these consequences is often determined by the nature and extent of the violation, the specific mandate or regulation that has been breached, and the subsequent impact on various stakeholders involved. Here, we delve into the potential consequences of non-compliance in more detail:
