Today’s IT systems are under increasing pressure from complex and constantly evolving cybersecurity threats. A single minor vulnerability can become the root cause of operational disruption, financial loss, and serious damage to a company’s reputation. Therefore, System Security Maintenance is no longer merely a technical maintenance activity—it has become a critical strategy in IT governance and system protection. This article explores common security risks, effective defense strategies, and the O&M Services Security solutions provided by BAP Software.
1. Why Is System Security Maintenance Essential?
As digitalization accelerates, IT systems have become the backbone of modern enterprises. Alongside growth opportunities, however, cybersecurity threats are increasing rapidly in both frequency and sophistication. Implementing System Security Maintenance—the continuous maintenance and protection of system security—is no longer optional; it is a fundamental requirement.
Increasingly Sophisticated Threats
Ransomware attacks: Hackers encrypt system data and demand ransom, causing severe operational disruption.
Phishing & Social Engineering: Employees are deceived into granting access, enabling attackers to exploit sensitive data.
Advanced Persistent Threats (APT): Targeted attacks that stealthily infiltrate and remain in systems for months.
Zero-day exploits: Exploitation of unpatched vulnerabilities in software or operating systems.
Common factor: A single weak link—whether a server, application, human factor, or internal network—can expose the entire system to risk.
Impact of Inadequate System Security Maintenance
Operational disruption: Production or business activities may halt for hours or days, leading to revenue loss.
Data loss: Customer information, financial data, and intellectual property may be leaked or stolen.
Reputational damage: Loss of trust from customers and partners, with long-term brand impact.
Regulatory violations: Standards such as GDPR (EU), NIST (US), and ISO/IEC 27001 require strong data protection. Non-compliance can result in multi-million-dollar fines.
Benefits of Implementing System Security Maintenance
Early detection & rapid response through continuous monitoring.
Reduced incident recovery costs: Preventive maintenance costs far less than post-breach remediation (IBM estimates the average cost of a data breach at ~USD 4.5 million).
Business Continuity Assurance: Systems remain available with minimal downtime.
Regulatory compliance: Meeting international security standards enhances credibility with global partners.
Increased trust: Customers gain confidence when their data and transactions are well protected.
Looking toward 2025 and beyond, System Security Maintenance is not only a risk-prevention measure but also a foundation for sustaining competitive advantage and ensuring secure, continuous, and resilient system operations.

2. Common Risks in System Security
Even with significant investment in IT infrastructure, enterprises still face common security risks. Understanding these risks is the first step toward building an effective System Security Maintenance strategy.
Risks from Software & Operating Systems
Security vulnerabilities: Applications and operating systems frequently reveal new vulnerabilities. Without timely patching, attackers can exploit them to gain access.
Example: The Log4j vulnerability (2021) impacted millions of systems worldwide.Outdated software: Many organizations continue to use legacy systems (e.g., Windows Server 2008, SQL Server 2012) that no longer receive security updates.
Cyber Attacks
DDoS (Distributed Denial of Service): Attackers flood servers with requests, causing service disruption.
Ransomware: Data is encrypted and ransom is demanded—this threat has surged significantly between 2022 and 2025.
Man-in-the-Middle (MitM): Attackers intercept data transmission between users and servers to steal sensitive information.
Brute-force / Credential stuffing: Automated attempts to guess passwords until access is gained.
Human Factor Risks
Lack of security awareness: Employees fall victim to phishing emails or malicious links, enabling system compromise.
Insider threats: Employees may intentionally or unintentionally leak data (e.g., copying to USB devices or mis-sending emails).
Poor access management: Dormant accounts and improper privilege assignments create exploitable entry points.
Infrastructure & Device Risks
Insecure IoT devices: Cameras, sensors, and other IoT devices are easily compromised if not properly secured.
Endpoints: Laptops and smartphones used for remote work without patches or antivirus software become attack vectors.
Public Wi-Fi networks: Employees working over unsecured networks risk data interception.
Data & Compliance Risks
Customer data leakage: Caused by insecure backups or cloud misconfigurations.
Lack of encryption: Plain-text data transmission is highly vulnerable to interception.
Regulatory non-compliance: Failure to meet standards such as GDPR (EU), PDPA (Singapore), ISO/IEC 27001 can result in severe penalties.
Real-World Examples
Colonial Pipeline (US, 2021): A ransomware attack shut down fuel supply systems, triggering an energy crisis and causing losses of hundreds of millions of USD.
Honda (Japan, 2020): Ransomware disrupted global production lines.
Vietnamese logistics companies (2023): Customer data leaks caused by cloud misconfiguration.
Security risks can originate from technology, people, data, and infrastructure. Without continuous System Security Maintenance—including assessment, patching, monitoring, and security training—organizations remain highly vulnerable to cyber attacks.

3. Effective System Security Maintenance Strategies
To protect systems against cyber attacks, enterprises can no longer rely solely on traditional firewalls or antivirus solutions. A comprehensive System Security Maintenance strategy must adopt a multi-layered security approach that integrates people, processes, and technology.
Establishing a Strong Security Baseline
Develop enterprise-wide security policies: Covering password management, access control, and Bring Your Own Device (BYOD) regulations.
Adopt Zero Trust Architecture: Every access request must be verified—no connection is trusted by default, including internal ones.
Regular patch management: Continuously update operating systems, applications, and IoT devices to eliminate known vulnerabilities.
Monitoring & Early Threat Detection
SIEM (Security Information and Event Management): Collects logs from multiple sources and analyzes anomalies.
EDR/XDR (Endpoint / Extended Detection & Response): Provides real-time detection of attacks targeting endpoints, servers, and IoT devices.
AIOps & Machine Learning: Leverages AI to predict and detect abnormal behaviors faster and more accurately than manual monitoring.
Identity & Access Management (IAM)
MFA (Multi-Factor Authentication): Multi-layer login using passwords, OTPs, and biometrics.
RBAC (Role-Based Access Control): Grants permissions based on roles, preventing unnecessary “super-user” privileges.
User lifecycle management: Promptly revoke or remove accounts of departing employees.
Backup & Data Recovery Strategy
3-2-1 backup rule: Three copies of data, stored on two different media types, with one copy kept offline.
Disaster Recovery Plan (DRP): Defines recovery scenarios for incidents such as ransomware attacks, power outages, or natural disasters.
Regular testing: Conduct recovery drills to ensure backup and restoration procedures function as intended.
